plant community or phytocoenosis: set of populations various plant taxons it populates a certain habitat it makes up a substantial component of

biocoenosis and the whole ecosystem characteristic for communities: structure specific composition

PLANT COMMUNITIES

seed bank: it is composed of viable seeds in the

state of vegetation standstill = dormant stand

they are accumulated in the soil they can gradually germinate and

complete the vegetation

PLANT COMMUNITIES

vertical structure (layer type): organization of plant parts into more or less

distinct layers – storeys above the earth and under the earth

surface storeys: trees bushes herbs moss root storeys

PLANT COMMUNITIES

PLANT COMMUNITIES

horizontal structure: layout of plant populations on the earth

surfacethe structure of communities is usually not fully unchangeable

big changes in the time, caused by the weather

seasonal changes of the phytocoenosis spring aspect of the floodplain forest

PLANT COMMUNITIES

mutual relations in plant communities: competitive mutualistic parasitic relations herbivora (planteaters) - plants epiphytism

PLANT COMMUNITIES

competitive relations: competition based on negative influence between two or

more organisms they use common limited source of nutrition interspecies competition introspecies competition the consequence of the competition is the

growth reduction and retardation of development and retardation of development

PLANT COMMUNITIES

mutual relations: Set of relationsbased on mutual positive

influence between both of the populations a) looser relations > by the pollination and

spreading of seeds by animals b) close symbiotic relations > mycorhisis,

nodule bacteria + French bean plants

PLANT COMMUNITIES

epiphytism: relation when a plant (epiphyt) is attached to

another one, which it uses as a pad algae cyanophyta lichens in equatorial regions: ferns higher plants
