1. Cláudia: the person and the primatologist
Even before the first class I attended
lectured by Prof. Claudia Sousa in 2011, I was well
aware of her work and her scientific reputation.
Actually, both Professors Claudia and Susana
Carvalho, were the reasons for my master
application at University of Coimbra. During those
academics years, Prof. Claudia an inspiring figure.
She had an outstanding career, pioneering several
topics in primate behaviour research. She was
committed, as well as passionate about her work
and she had a unique approach to primate
conservation.
Her will to take risks took her to Japan
where, in the very first years of her career, she
developed brand new theories about the use of tokens as reward and as tools in
captivity. She described tokens as “symbolic tools” (pp. 413) with exchangeability
characteristic, aiming to infer cognitive skills and food preferences and preference for
non food items, demonstrating that chimpanzees “can evaluate the costs and benefits of
their actions, maximizing their choices” (pp 429) “and adjusting their behaviour
accordingly” (pp. 434) (Sousa and Matsuzawa, 2006). This token system method
allowed further analysis of social learning, in particular the social transmission of skills
from mother to infant and the intrinsic motivation to copy (Sousa et al., 2003). But Prof.
Claudia also studied tool use in wild chimpanzees of Bossou. She focused on the use of
leaves to drink water, assembling important knowledge about laterality and social
learning and, as a result, revalidating the idea of culture transmission across generations
and communities in chimpanzees (Sousa, 2011; Sousa et al., 2009; Biro et al., 2006).
She also wrote about the role of emotion and social cognition of emotion (Bard et al.,
2004) and later in her career, she focused on human impact over wild chimpanzees
populations, in particular in Guinea Bissau (e.g. Hockings and Sousa, 2012, 2013;
Sousa et al., 2014; Sousa and Frazão-Moreira, 2010), developing conflict-mitigation

strategies in support of both wildlife and local people, integrating sustainable managing
of protected areas and local socioeconomic development. For instance, some of her
latest work, focused on chimpanzee nesting behaviour and ecology, an effort to
underline deforestation as major concern to this species conservation.
Her reputation was even reflected in the several scientific associations and
societies she was part of (APP (president), CRIA (founding member), APA, SPE, IPS,
APE, ISE). In the meantime, she took the time to lecture at the Nova University of
Lisbon and at University of Coimbra. I meet her in the later, attended classes and I first
told her about my wish of becoming a primatologist. She was committed to help
Portuguese students pursuing international careers within the field. She knew of the
limitations that existed in Portugal but she had hope that a joint education and training
with the Kyoto University could help the Portuguese students to continue their studies
and, perhaps, make a bridge between the two countries.
However, in my case, I took some failed attempts to finally reach Japan. After
some difficulties with my first Master thesis proposal, Prof. Claudia immediately helped
me with a second research plan, with the same energy - no matter what personal
problems she had, she didn’t let those problems influence her work and consequently I
felt always secure and well guided. When I concluded my Master dissertation (in
Portugal), Prof. Claudia continued to push me further – she suggested and guided me
through the Monbukagakusho (MEXT) scholarship application for a PhD in Japan.
Unfortunately, I didn’t get the scholarship and my dream had to be delayed once more.
But Prof. Claudia did not give up on me and kept offering invaluable help. Sadly, our
projects were interrupted. Too soon.
This Fund in her memory, it is more than just to honour her career. This is the
continuation of her work and efforts. She lives through her students who admired her
and were inspired by her. And miss her very much.

2. Application process to the “Cláudia Sousa Memorial Fund”
This section aims to help the next students through the application process.
This fund intends to encourage and inspire Portuguese students to engage in
Primatology. It targets students and junior researchers in an early stage of their career,
looking for the opportunity to carry out an internship in one of the most important
Primate’s research laboratories in the world. One student, interested in pursuing a
scientific career in Primatology, will be given the chance to engage in the Primate
Research Institute’s activities (Inuyama, Japan) and at the same time, experience the
Japanese culture. Portuguese graduate and under-graduate students may apply to this
grant, with the permission from their course lead or supervisor.
A grant will cover one round-trip, travel expenses in Japan, accommodation and
a stipend. Students may chose to stay 1 and 3 months in Japan, and during the stay, are
expected to participate in the ongoing research activities, attend seminars and visit key
places for the study of primates in Japan.
Applicant should submit in one single file (English) with:
applicant’s name, affiliation, career stage, two names of referees
(with affiliation and e-mail) and proposed duration and schedule of the grant;
cover letter directed to the selection panel, describing Prof.
Cláudia career and how her work have inspired the applicant,
updated CV.

3. Primate Research Institute and Primatology in Japan
Primatology in Japan had an
early start by the hand of Dr. Kinji
Imanishi in the 1940s. Unlike other
industrialized countries, Japan has a
combination of two vital factors for
the study of primates: an important
part of its territory is evergreen and
its natural fauna includes an endemic
primate species, the Japanese monkey
(Macaca fuscata). Research in Japanese monkeys started in 1948 by command of Kyoto
University who is until today one of the most highly regard and dynamic institution for
Primatological research (Huffman et al. 2013). In these very first years of development
of Primatology in the country, a pioneering research team from Kyoto University, made
their first outstanding discovery in Koshima Island, one that would change the way that
humans see other primates and would be the centre of discussion until our days. This
team was leaded by Dr. Imanishi, composed by Dr. Masao Kawai, Dr. Shunzo
Kawamura, and Dr. Junichiro Itani (Huffman et al. 2013). Researchers were at that time
provisioning the macaques for a closer observation of their behaviour when, in 1953, a
young female started to wash the sand off the sweet potatoes given by the researchers
and later, washing it with seawater for a saltier taste (Kawai, 1965). This amazing
behaviour soon spread to the others group members and latter through generations, and
being now performed by all individuals of the group. For the first time, the term
‘culture’ was associated with other species beside the human species. In fact, the debate
over the phenomena of “pre-culture” (used by Kawai) or “sub-culture” (used by
Kawamura and Imanishi) in macaques were the starting point for the subsequent
international massive research on social learning and traditions in primates (Kawai,
1965).
Back in Inuyama, due to the effort and dedication of Dr. Imanishi and
colleagues, the Primate Research Institute of Kyoto University (KUPRI) was
established in 1967. This institute is one of the most prominent centres for
Primatological research in the world, covering several areas of the field, such as
Fig. 2. Dr. Imanishi and his students (Itani Junichiro
Archives).

biology, behaviour, cognitive and socio-ecological features of primates, aiming also to
uncover the human mind and its evolution. This institute played a vital role for the
development of comparative cognitive science. The main subject of this discipline is our
closest living relative, the chimpanzee. With this purpose, Dr. Kiyoko Murofushi, Dr.
Toshio Asano, Dr. Tetsuya Kojima and Dr. Tetsuro Matsuzawa founded in 1978 the Ai
Project. For the first time researchers focus was not simply on teaching symbols to
chimpanzees, but instead, they were trying to understand the actual learning process –
“the perceptual and cognitive basis of language-like skills” (Matsuzawa, 2003: 5). In
other words, understand how animals see the world.
But overseas, Japanese researchers were also pioneers regarding wild habitat
primate research. In the 1958, Dr. Imanishi and Dr. Itani went for the first time to
equatorial Africa to conduct a pilot survey of gorillas, funded by Japan Monkey Centre
Institute and Museum of Primatology (Itani Junichiro arquives web). Ever since,
Japanese research teams have conducted long-term research in several points of Africa.
In one of the first crusades, in 1960s, Dr. Toshisada Nishida succeeded in habituating
chimpanzees to close human presence in Kasogue, Mahale Mountains (Tanzania). Later
he came to report that different chimpanzee’ communities presented differences in tool-
use such as ant fishing (Nishida, 1973). More recently, major findings on tool use
behaviour were made in a habituated chimpanzee community in Bossou, where Dr.
Yukimaru Sugiyama arrived for the first time in 1976 (Matsuzawa, 2003).
In sum, several long term research sites in Africa territory are being run by
Japanese teams such as Bossou, Mahale, Wamba, Kalinzu and Kahuzi. Comparing
studies of both “indoor laboratory” and “outdoor laboratory” presents a unique and real
opportunity to test preconceived theories and to understand the processes underlying
behavioural processes. This may well be the best way to shed light on some current
scientific questions and launch the discussion of several others. In that line, KUPRI has
now two new centers aiming to break boundaries and bring together young and senior
researchers for all over the world. Both CICASP (International Course in Primatology
and Wildlife Research, 2009) and PWS (Leading Graduate Program in Primatology and
Wildlife Science, 2013) aim to boost international collaboration and to grew a new
generation of skilled experts in wildlife, conservation, welfare and education.

a. Seminars in PRI
In PRI, students and interns have the opportunity to attend several seminars,
both from senior researchers and students. Seminars aim to launch discussion and
debate over the ongoing research being conducted in PRI. These events are also a great
opportunity to students to have some feedback and comments on their research.
Seminars schedule is:

b. Research Project: The impact of the change of facilities on a
group of chimpanzees at the Primate Research Institute of
Kyoto University
Introduction
Captive environments impose limitations to the behavioural opportunities
available to their inhabitants (Hosey, 2005). Adequate conditions demand complex
environments which are related to the expression of natural behaviour repertoire
(Mallapur, 2008). Although historically the amount of space provided has been
emphasized, more recently the importance of the quality of space has been realized. In
fact, understanding how animals integrate their surroundings and how they use the
available space is critical to improve the existing captive management practices,
enclosure design and ultimately, animal welfare (Estevez and Christman, 2006; Ross et
al., 2011). However, few studies quantify captive animals’ space use (e.g. Jensvold et
al., 2001 for chimpanzees, Ross et al. 2011 for chimpanzees and gorillas; Stoinski et al.,
2001 for gorillas). In the case of the chimpanzee, this knowledge acquires even more
significance as chimpanzees are characterized by a fusion-fission social system,
meaning that opportunity to group division may play a role on social dynamic, health
and welfare of individuals. This study aims to document the behaviour of 8 captive
chimpanzees at Primate Research Institute to the new enclosure (Green cage) compared
to the old facilities (Grey cages). We wish to assess the changes on the space occupation
8
and activities of the different individuals of the chimpanzee group.
We are presenting the preliminary results of our ongoing research, focusing on
the green cage.
Study site and methods
The present study was conducted at Primate Research Institute. The captive
group of resident chimpanzees at PRI include, at the moment, 9 females and 3 males,
divided by two subgroups: Akira (8 individuals), Gon’s group (3 individuals) and one
individual isolated for rehabilitation purposes.
The old facilities include two Grey cages (an East Sunroom, W9.9m x D13.3m x
H10.0m, and a West Sunroom, W9.8m x D13.3m x H10.0m), an Open-air enclosure and
the new Green cage (W14.2m x D19.5m x H15.7m).
Each group has daily access to one of the grey cages. Akira’s group may also
occupy the green cage. However concerning the access to the open air enclosure, and
because the two groups cannot share that space simultaneously, a schedule for accessing
the open-air enclosure was designed as follows:
Akira’s group: Tuesday and Thursday,
Gon’s group: Monday, Wednesday and Friday.
The behavioural data was collected 1 to 3 times per day by three researchers
(Anne-Claire, Prof. Misato Hayashi and Raquel Costa) in the possession of a Certificate
of Husbandry and Experiments on Primates. Baseline was collected for both groups by
Anne-Claire during the summer of 2015. After the opening of the green cage (October,
8th, 2015), data was collected by Prof. Misato Hayashi and Raquel Costa focusing only
on Akira’s group until December the 9th. Data was coded, with the support of a cam-
corder, using instantaneous scan sampling every 15 seconds (10 minutes focal per
session) of all animals visible to the researcher, based on a behavioural catalogue of 20
behaviours and the facilities mapping. The focus period to collect data was 12-13h
because during this time chimpanzees were not occupied by the ongoing cognitive
experiments.
Statistical analysis
To verify or disconfirm significant differences between the two conditions and
individuals’ behaviours throughout the experiment, the software SPSS version 20 was
9
used for the statistical analysis.
We have calculated a general rate of recurrence per animal per behaviour. We
looked for significant changes in each behaviour. As data is non-normally distributed,
we used non-parametric methods of analysis. We first used a Kruskal-Wallis test
(comparing multiple independent samples) when comparing data collected in the
summer (before the green cage) and data collected during the fall (including the green
cage) concerning only the lunch time period. The same method was applied to explore
data collected during the fall, including the tree cages and including all daily sessions.
Because fall data base was collected by the author of this report, we will focus on this
last. The significant differences (P< 0,005) given by this test were then explored by
Mann-Whitney U test (comparing two enclosures at the time) in order to verify
enrichment influence over animals’ behaviour.
Preliminary results
A. Brief comparison between summer and fall observations during
lunch time period
When comparing behavioural data from last summer to data collected in the fall
focusing on lunch time period, statistical analysis revealed significant differences
(p<0.05): “interaction” (p=0.006) increased in the green cage as well as “move”
(p=0.036) and “non-visible” (p=0.000). Moreover, “lay” behaviour showed the
tendency to decrease in the green cage (p=0.005).
B. Analysis within the Green Cage Condition: Fall 2015
When we compare the behaviours occurred in the green and the grey cages
during the fall observation period and considering the three sessions per day (morning,
lunch time and afternoon), data showed that “chase” (p=0,01), “coprophagy” (p=0,011),
“interaction” (p=0,024), “lay” (p=0.014) and “stand” (p=0,035) had a significant
change. “Chase” (mean=0,004; SD=0,007) and “coprophagy” (mean=0,002; SD=0,003)
occurred only during the green cage period. “Interaction” (mean=0,005; SD=0,012), lay
(mean=0,196; SD=0,153) and “stand” (mean=0,003; SD=0,005) were higher in the
10
green cage and lower in the grey cage.
Figure 3. Comparison between enclosures of the behaviours which presented a significant change.
C. Individual differences in Activity, Inactivity, Interaction and
Abnormal behaviour
This section aims to document the individual changes in activity, inactivity,
interaction and abnormal behaviour in the green cage. Individual differences in the grey
cage and in the open air enclosure will not be presented as data collected per individual,
since they are not enough to establish a fair comparison. For example, there is almost no
data collected in the grey cage for Pendesa and very little data was collected for Pan in
the open air enclosure - the following table shows the number of sessions per individual
and per enclosure.

Instead, individual differences in the activity budget will be presented focusing
on the green cage enclosure. However, when interpreting our preliminary results,
caution should be taken due to the difference in the number of sessions between
individuals.
“Inactivity” was the predominant behaviour in almost all individuals, with
stronger effect in Ai and Akira. Ayumo was the individual presenting higher levels of
abnormal behaviours, followed by Pendesa, while Mary, Pan and Ai were never
observed doing such behaviours. “Interaction” levels were greater in Chloe, Cleo and
Mary. Cleo was also the most active individual in the group and she was actually more
active and interactive than inactive during her sessions in the green cage.

D. Space use preliminary analysis
Data collected about the environmental features used by the chimpanzees show
that all floors were used, inclusive ground floor and the tunnel to access others
enclosures. However, the 4th
floor is widely preferred. Note that the tunnel entrance is
located in the 4th
floor.

Discussion
This study aims to identify the patterns of chimpanzee’ behaviour and space use
in the new enclosure, designed to increase space availability and complexity, in an
attempt to improve animal’s welfare in PRI. Our preliminary results show that the new
facility did indeed have an effect on chimpanzees’ behaviour. When comparing Akira’s
group behaviour in the grey cage during summer, to data collected in green cage in the
fall - and focusing on lunch time period - statistical analysis revealed that moving
behaviour increased in the green cage while “lay” behaviour decreased. These
tendencies reveal that animals were more active in the green cage, maybe because they
were more prone to explore the new facility. On the other hand, “interaction” also
increased in the green cage which is an indicator of an increase in group social dynamic.
When we compare the behaviours occurred in the green and in the grey cages
during the fall observation period, and considering the three sessions per day – meaning
that the both enclosures are available simultaneously -, data show an increase in
“interaction” behaviour and “chasing” behaviour in the green cage, matching with the
previous comparison between summer and fall. However, data also show an increase in
“lay” and “stand” behaviour (inactivity) and the emergence of “coprophagy” (abnormal
behaviour). Caution should be taken when comparing these results as our data is biased
towards the green cage – when presented with the opportunity to choose between grey
and green cage, animals would normally prefer to stay in the green cage, unless it was
too cold or raining. Consequently, we have more data in the green cage as shown in
table 2.
Individual analysis in the green cage reveals that individuals have different
activity budgets. Particularly, Ai and Akira who were very inactive, Ayumo and Pendesa
who presented abnormal behaviours (such as hair pulling and regurgitation), and Cleo
and Chloe who interacted greatly by grooming (with each other and by providing
grooming towards others). The fact that Chloe and Cleo were more prone to interact
with others may be related with the hormonal changes (uninterrupted estrus cycle) that
both individuals were experiencing. However Pan, enduring the same hormonal
changes, did not present the same increase in interaction, which may be related to her
low ranking position.
Space analysis shows that chimpanzees used all floors but preferred the highest
floors, a similar result to that of Jensvold et al., 2001 study. This was an expected result
14
related to the chimpanzees’ natural motivation for climbing. On the other hand, the fact
that the 4th
floor was the preferred place to be, may also be related to: 1) being the same
floor connecting to the grey cage (and so, it’s closer to return to another space in case of
disturbance in the green cage) and 2) possibly presenting a better view of the outside
(the rhesus monkeys enclosure or the human passages and accesses). Another study, of
Ross and colleagues 2011, found that apes (chimpanzees and gorillas) used small
fractions of the available space in the enclosures, which is also in agreement with our
results. However, this outcome does not suggest that captive chimpanzees do not need
larger enclosures. In contrast, the freedom to chose where to stay and with whom,
granted by larger and more complex environments, may play an important role in
individual welfare. In the present case, the difference between the number of sessions of
each individual (and authors’ personal observation) relates to the division of Akira’s
group into sub-groups – in each observation period, some individuals were present in
the green cage and therefore observed while others were not. So, it’s clear that
individuals chose to be in the green cage depending on: 1) their preferred spot in the
green cage; 2) the individuals that are already inside the enclosure. In that sense, even
not fully used, the new space availability seems to have contributed greatly to the
performance of chimpanzee’s natural fission-fusion system. In fact, as mentioned
before, our data show an increase of “interaction” in the green cage compared to the
grey cage, which suggest a more peaceful social dynamic within the group. Further
research may clarify the details of these grouping patterns, correlating as well with
social rank and estrus cycle. More data should be collected in the grey cage and the
open air enclosure to complete our data base.
c. Genome Course (October, 26-30th
, 2015)
The main focus of this genome
course was to identify gender of Sika
deers via DNA analysis. More
specifically, we had to compare our
results from the molecular analysis to
our field observations of the animal’s
Fig. 13. Preparation of samples.

gender. During this genome course, we first extracted DNA from the samples we
collected in the field (Yakushima Field Course). Next we purified the sample and
quantified its DNA, using the Qlamp Fast DNA Stool Mini Kit. However, our
quantification showed a very low DNA concentration. Subsequently, we performed a
PCR (Polymerase Chain Reaction) using primers SRY (to determine the Y autosome)
and ZFXY (to determine X and Y autosomes) followed by an Electrophoresis. The
results showed that DNA ws in fact a good tool to determine gender. Nevertheless, some
points have to be considered in the
future: DNA preservation is difficult and
PCR is not stable. In order to address
these problems, we should improve
extraction methods and adapt the PCR
conditions to the samples.
The second part of this course was
sex identification by hormonal analysis.
Our aim in this part of the course was to
identify deer gender via hormonal
analysis, by comparing concentration
levels between sexes and also between
breeding season (our sample) and non-
breeding season (a previous sample
collected in August). In order to do that,
we used a spectrometer to measure the concentrations of hormones in our samples.
Results showed no difference between males and females in each season, but showed a
significant difference of Estradiol-17B between seasons (with higher level during the
non-breeding season). Our results may be explained by the high standard deviation,
from the inefficient data collection method and for contamination in the lab.
To summarize, we came to the conclusion that the three methods (direct
observation in the field, DNA and hormonal analysis) are together an effective tool to
determine the gender of deers. This knowledge is of the outmost importance for animal
management’s policies, and in this particular case, for the development of an
appropriate hunting policy, concerning the Yakushima panorama. I used this opportunity
to learn basic methods in of DNA and hormonal analysis.

5. Zoological Parks in Aichi and Kyoto Prefectures
a. Japan Monkey Centre (Inuyama)
Japan Monkey Centre
(JMC) was established in October,
17th
, 1956 by the same team of
primatologists who “invented”
Primatology in Japan. JMC has
proved to be more than a zoo. Since
the opening, JMC has been a
popular centre for public education
and awareness, promoting research,
conservation and welfare.
Thousands have visited JMC, from
a wide range of ages, including schools (from elementary to high schools) and academic
researchers. As previously mentioned, JMC funded the first expedition to Africa in
1958, taking Dr. Imanishi to see wild gorillas. In addition, JMC funded in 1960 Dr. Itani
expedition to Gombe and in 1971 the first Japanese expedition to Amazon by Dr. Izawa.
JMC is home to more than 1000 primates of 66 different species, from lemurs to
great apes. It is divided into several sectors, including a visitor centre, a Madagascar
house (open air enclosure with brown lemurs, black lemurs, and ruffed lemurs), a South
American House (Callitrichidae monkeys and nocturnal monkeys), an Asian House (e.g.
rhesus macaques), a Wao Land (an open air enclosure in which the visitor can enter to
observe closer the free-moving ring-tailed lemurs), an African Centre (with great apes
and nocturnal monkeys), an African House (e.g. hamandryas baboons and colobus
monkeys), a Castle of Baboons (Anubis baboons), a Monkey valley (Japanese
macaques), a Monkey scramble (siamangs, spider monkeys and squirrel monkeys), a
Gibbon’s House (agile gibbons, capped gibbons, white-handed gibbons, and muller's
gibbons) and a Petting zoo for kids with small mammals and reptiles.
It incorporates also a museum directed by Prof. Yamagiwa. The museum has a
database (Captive Primate Collection, CAPriCo) of more than 6,300 specimens’ remains
(skeletal, formalin-preserved brains, organs and parasites). The JMC museum published

“Primates” for the first time in 1957 –
it’s the oldest scientific journal focused
on Primatology written in English.
This journal is currently published by
Springer in collaboration with Primate
Society of Japan.
JMC became a “Public Interest
Incorporated Foundation” in April
2014. Prof. Matsuzawa is the General
Director and Prof. Oike is the
President.
b. Higashiyama Zoo and Botanical Gardens (Nagoya)
Higashiyama Zoo and Botanical Gardens first opened to public in 1937 and
survived the air raids of 1944. It is home for more than 500 species of animals and you
can find more than 7000 plant species in their Botanical Gardens and Green House. The
park includes an amusement park and the Higashiyama Sky tower. It was considered
one of Japan’s largest zoos and the second most popular Zoo after Ueno Zoo (Japan
visitor website) with more than 2 million visitors per year (Japan365days website).

c. Kyoto City Zoo
Kyoto City Zoo was the second zoo established in Japan. We were in April 1903,
no special ceremony was held but many people attended its opening. At that time, the
zoo sheltered 238 animals of 61 species. On February 1910, the Zoo succeded in
breeding lions for the first time in Japan. By its 10th
birthday, the zoo had doubled the
number of species. In the following years there were more species, more animals and

more space. But during the WWII, the number of species decreased to 72. The crisis in
Japan during the war took its toll on the Zoo and its animals. Several animals died of
malnutrition and from the cold. The most dangerous animals had to be killed under
military’s commands as a precausion regarding air raids. Part of the zoo land was even
occupied by the Japanese army from 1956 to 1950. After that crisis, the zoo recovered
and at 1953, three trigres were born as well as one ostrich by artificial incubation, both
events were the first of it’s kind in the country. In the following years, the zoo continued
to be the first to succed in several species’ breeding programs and received te first
“Koga Prize” in 1987. It has also began to held educative training and workshops for
young students and built a library. By the time of its 100th
aniversary, Kyoto City Zoo
had its record of animals: 721 animals of 175 species. After that, the zoo continued to be
award for breeding programs and in April 2008 concluded the agreement with Kyoto
University for a joint cooperation.

6. Travelling
a. Kumamoto Sanctuary
In April, 2007, the first Chimpanzee Sanctuary in Japan was created under the
name of Chimpanzee Sanctuary Uto. Its purpose was to rehabilitate almost 100
chimpanzees that had been subject to invasive biomedical research for several decades.
The pharmaceutical company responsible for the animals, agreed to relinquish their
work and yield the infrastructures and animals to Kyoto University. Later the sanctuary
changed its name to Kumamoto Sanctuary (KS). KS aims to rehabilitate the same
animals who participated in those same invasive experiments and several others
(including 6 bonobos) coming from other captive settings in Japan, who also joined the
safety of this sanctuary. Some animals have deceased and some others were sent to
zoological parks around Japan. For the time being, KS is home to 57 chimpanzees and 6
bonobos. Its building structure resembles that of a puzzle, setting an environment
allowing fission-fusion social dynamics. In addition, manipulative enrichment is given
to the animals, aiming to improve their welfare.
The large number of individuals, the proper captive settings (with individuals
booths and empty large rooms for behavioural experiences) and the close interaction
between human keepers and animals, provide researches the opportunity to conduct
unique and pioneer behavioural research in KS. Currently, ongoing research in KS
focuses on gazing, memory and social interactions.

b. Primate and Wildlife Science (PWS) Courses
Sasagamine (October, 1-4 th
, 2015)
The main focus of this training course was to learn survival techniques and
climb the Mount Hiuchi. In the first day we learnt some basic characteristics of local
vegetation (for example, distinguish some toxic plants) while collecting wild berries.
Afterwards Prof. Sugiyama held a lecture on local fauna. He showed us video montages
of wild foxes and badgers. Specifically, he showed us some individuals known to live
and forage near the lodge. Although in the following days we tried to observe them, we
missed that opportunity. On the other hand, we did observed wild Japanese macaques
closely, in the second day while walking near the lodge. We also caught a Japanese four-
lined rat snake, which we examined and photographed before release. But this encounter

also had me realize that we should always pay attention, not only to the floor, but also to
the tree branches as some species of snakes (like that one) can climb and move around
trees. Another great skill we learnt was how to read a map, a lecture given by Prof.
Yamamoto in the second night – this is very important and helpful and I’ll apply this
knowledge in my future field work. Prof. Yamamoto also gave us details about the
hiking trail in Mount Hiuchi, precise instructions and advices. In the next day, we set to
the Mount Hiuchi as scheduled, with a perfect weather. We started at around 1300
meters (from the lodge) at 6 am and reached the summit (2496 meters) at 1130 am. We
included regular rest stops throughout the duration of the climb and we walked in an
appropriate speed in order to maintain our strength and also to enjoy the beautiful view.
In the summit we could see the other mountains, including Mount Fuji. We returned at
the lodge at 1700 pm - exhausted but in high spirits and so, in that night, we had a
bonfire near the lodge. In the last day, Professor Yamamoto gave us a lecture on rope
work, exemplifying with several types of knots with different functions, which may be
used in numerous situations. On the other hand, Professor Koshima lectured us in the
uses and functions of bivouac, a very useful item for camping. Such equipment may
actually be life-saving in case of emergency as it may keep us dry and warm in harsh
conditions or it even may serve to carry an injured companion.
Through this experience, I acquired some survival and climbing skills which will
be of great help in my future field work. More than theoretical lecture, this course
provided students the real applications of several techniques. It had also demonstrated
the importance of team cooperation, adaptation and flexibility in the field. In the end, I
was left with the desire to return to the “hűtte” and to explore more its surroundings.

Yakushima Field Course (October, 18-24th
, 2015)
The main focus of this training course was to understand the relationship
between body size, age and faecal pellet in Sika deers (Cervus nippon yakushimae) in
Yakushima Island. Current populations of Sika deer are increasing continuously since
1950, leading to some researchers to believe that damage to the vegetation caused by
bark stripping, grazing and browsing by these animals, will soon raise to a serious
ecological problem in the island. In order to contribute to the control and management
to this species, our research aimed to prove the correlation between pellet size, age and
sex in Sika deer, using a non-invasive method of data collection. In fact, the last official
census of the Sika deers in Yakushima dates from 2011 and currently pellet counting
methods have became a vital tool for wildlife population census, granting additional
knowledge of sex and age structure, growth, mortality and reproductive status of the

population. Our data collection consisted in tracking the deers (from 745am to 1500pm,
day 19, 20 and 21) on the western shore of Yakushima Island, in Seibu Rindo, between
road and low-land (secondary and primary forests). After encountering one deer (or a
group), the researchers followed and wait for the animal to defecate. The faeces were
then swabbed for DNA analysis and collected in marked plastic bags. A camera was
used to record a video of the animal and a video of the researcher holding a measure, to
latter estimate the animal’s high. In the lab, pellets from each sample were counted and
measured (longer and shorter axis) as well as conducted the video analysis to calculate
the deer’s body size. Concerning the statistical analysis, we found no correlation
between the body size and the size of the pellet but we did find a significant relationship
between adults and juveniles for both long and short axis, suggesting that pellet size is
affected by age. However, our study faced some limitations: small sample size (biased
to females), inaccurate method of the animals’ body size estimation, possible
contamination. To overcome these limitations, we suggest that future research should
use more age classes, should compare several sites and between low-land and high-land
populations. In conclusion we suggest that the pellet method can indeed be used to
census Sika deers populations. Our results were presented to Professors and other team
in the day before leaving the site.
Personally, I used this opportunity to observe wildlife (Japanese macaques
(Macaca fuscata), deers and their inter-specific interaction). I’ve learned how to
integrate methods (observation data collection, physical data collection and their
consequent analysis), analyzing and discussing results critically. Through this
experience, I have developed the notion of team cooperation and how to overcome
problems and obstacles related to research. Finally, this course granted me the basic
information of some methods that I’ll use in the future.

b. Iriomote Islands Tour
Iriomote is the second largest island in Okinawa and it’s famous for its
biodiversity. The most celebrated endemic species is the Iriomote Cat, classified as
Critically Endangered (IUCN), with a population estimated in 100 individuals. Another
special feature of Iriomote is the mangroves. A mangrove is a self-sustaining system,
with salt tolerant trees presenting a complex root system. It’s also home to many aquatic
organisms, such as fish, crustaceous and molluscs. It plays an important ecological role
and is vital for the protection of coast areas. We could observe several species of
mangroves from very close distance by kayak at the same time we enjoyed the beautiful
landscape. In Hoshizuna-no-hama paradise beach, we walked on “little stars”- calcium-
carbonate foraminifera grinded from the coral reefs, which we had also the opportunity
to visit by snorkelling. We also visited several waterfalls (Mariyodo-no-taki, Kampire-
no-taki and Pinaisara-no-taki) and by night we walked surrounded by fireflies.
Before returning to Inuyama, we were presented the chance to visit the Ishigaki
Yaima Village, Japan Registered Cultural Heritage. In Yaima Village, we walked
through a Japanese traditional village with relocated private houses and replicas of
traditional fishermen and farmers’ homes. Yaima also included a Squirrel Monkey
Garden and a mangrove forest, protected under the Ramsar Convention.
This tour gave students the opportunity to survey and explore this subtropical
island, with special note for Iriomote-Ishigaki National Park which comprises both
mountain and mangrove forests. Personally, I used this opportunity to observe wildlife
in a subtropical habitat. I was mostly impressed by the flying foxes, the crested serpent

c. Uganda, the “Pearl of Africa”
Uganda is an east-central African country, known it’s natural treasures such as
Bwindi Impenetrable National Park (NP), Rwenzori Mountains NP (both UNESCO
World Heritage Sites), Kibale NP and Queen Elizabeth NP, between others. Impressed
by its landscapes, wildlife and cultural traditions, Winston Churchill, during a
diplomatic visit to the country in the beginning of the XX century, described Uganda as
the “Pearl of Africa”. In fact, Uganda is ranked in the top ten countries in the world for
biodiversity by the Convention of Biological Diversity. Uganda encloses a great variety
of habitats, including tropical, mountain, savannahs and wetlands.
My journey through Uganda started with the African Primatological Consortium
(APC) conference in the Makarere University, Kampala. The theme of this conference
was “Building African Primate Research and Conservation networks”. This meeting

brought together Japanese and African researchers in an attempt to coordinate a
collaborative research plan that will integrate academic and conservation efforts as well
as the support for young African primatologists.
The second step in my journey was visiting the Ngamba Island Chimpanzee
Sanctuary. Located in Lake Victoria, Ngamba is home to 48 chimpanzees, rescued from
illegal and tragic situations throughout the country. The animals find in Ngamba Island
an ideal setting for rehabilitation – 100 acres of secondary forest habitat of which, 98
are reserved for chimpanzees, in a wonderful landscape which mimics perfectly their
natural habitat. To help further their recovery, chimpanzees at Ngamba can count on the
care, devotion and affection of the very enthusiastic care keepers. People like Dr. Titus
Mukungu (sanctuary manager) Phillip Sekulya (assistant sanctuary manager in charge
of administration), Innocent Ampeire (assistant sanctuary manager in charge of
animals), Paul Nyenje, Amos Okello, Byron Ssemambo, Enos Sebina Kiwagalo, Joseph
Masereka, Kyama Stanly, Betty Angucia (keepers), Erina Kansiime, Richard Kaahwa,
Harriet Namuli (volunteers), Moses Bageya, Hategeka Stanly, Ronald Bataze, John
Mutambo, Samuel Wenwa (Chefs), Grace Namatovu (house keeper), Simon Nuwagira
(gardener), Ojok Borneface (maintainance), Silver Birungi James(education officer),
Hanifa Chandiru (Volunteer in administration), Dr. Joshua Rukundo (Conservation
Programs Director) and Lilly Arajova (Executive Director) to whom I wish to extend
my deepest gratitude and respect. In addition to animal welfare, public awareness is also
one mission of Chimpanzee Trust’s as local and foreigner communities play a vital role
in the species’ conservation and their natural habitats. During my stay in Ngamba, I was
told the chimpanzee’s backgrounds, I’ve learn the husbandry methods and more
importantly, I was told the future steps and the needs to sustain the current work.

Saying goodbye to Ngamba, I headed to Kampala, where I joined the team I’d
travel with to Bwindi and Queen Elizabeth NPs.
Bwindi, located in the south-western Uganda and border with Virunga National
Park, is most celebrated for the approximately 350 mountain gorillas (half of the
world’s population). Mountain gorilla (gorilla beringei beringei) is classified as
Critically Endangered (IUCN), with a population estimated in 650 individuals. The park
is owned by the Uganda Wildlife Authority and fully protected. In Bwindi, four groups
are habituated to human presence: three for eco-tourism and one for research. During
the two days I stayed in Bwindi, I visited Mubare’s group and Habinyanja’s group. Both
groups have one or more infants, meaning that population is recovering. However
poaching is still a threat and rangers continue to patrol the park. Neighbouring the park,
population density is very high and very poor. A well planed eco-tourism (with strict
rules to protect both animals and people) is therefore a vital source of income to local
communities. In fact, near the Buhoma entrance gate, several stores, lodges and markets
are placed to sustain tourism as the gorilla tracking is the park’s main source of revenue.
A good example of how tourism may help local populations is the Bwindi Community
Hospital (the best Hospital within 70 kms).

Next adventure was Queen Elizabeth Park. We had the opportunity to do a Safari
and a boat cruise. I was mostly impressed by the diversity of mammals and birds. We
waited 2 hours but we managed to observe and photograph a male lion and 3 females,
which is a rare event. In the end of the day, we visited a salt mine and learnt more about
the local community life in that area.

At last, my final experience in Uganda was Uganda Wildlife Education Centre in
Entebbe. In here, I watch some animals I was hoping to see in Queen Elizabeth NP, such
as the leopard and the shoebill crane.

This experience was both a dream and a preparation for my future research
project. I left Uganda with the certainty that I will return. It was the perfect motivation
and inspiration to the beginning of my own research.

7. Conference
SAGA 18 Kyoto
SAGA is the acronym for Support for African/Asian Great Apes, established in
1998, with the main objective to gather researchers, keepers, conservationists and
general public all over Japan, to discuss ongoing studies, conservation and welfare of
captive apes. SAGA three principles are: support of species conservation in-situ,
improvement of captives individual’s welfare and reduction of invasive research on
great apes. Last SAGA meeting was held in
Kyoto Zoo in November, 14-15th
, 2015.
Students were given the opportunity to learn
from wildlife experts talks (i.e. Prof.
Matsuzawa and Prof. Yamagiwa (Kyoto
University) and Dr. Ross (Lincon Zoo)) and to
present their own work in a poster presentation
open to general public. This year, 55 posters
were presented in SAGA 18. Next meeting,
SAGA 19, will be held on November, 19-20th
,
2016.
