Forensic PalynologyStudy of pollen, spores, and other microscopic plant parts

Pollen and SporesNatures Fingerprints of Plants

Dinoflagellate Algae Fungal sporesPollen BackgroundPollen is the male cell of flowering/cone bearing plantsMicroscopicFound on nearly everything (unknowingly )Locards PrincipleComes in a vast array of shapes, sizes, aperture openings, & surface textures

Pollen BackgroundUsually pollen types of different species within a single genus look similar

Different species of daisiesPollen Diversity

Hay Fever Pollen

Forget-Me-Not

Persian Silk Tree

Willow Tree

Pine Tree

Pollen PrintsEach location produces a unique pollen print that is often so specific that it can be used to identify that precise location

Kansas Prairie

Texas

Louisiana

Georgia

Uses in forensicsIdentify the pollen/minerals and determine where they came from and when they occurDetermine if a body was in a particular place at a certain timeSeason in which crime was committedPollen Tells a StoryFor instance, a dead body may be found in the woods, and the clothes may contain pollen that are found in a place other than where the body was found. That indicates that the body was moved.

How to Analyze PollenUsing a microscopeLook for characteristics such as shape, size, surface texture, & apertureCompare specimens (from crime scene to suspect, from victim to suspect etc.)Provides a piece to the PuzzleWill probably not be the sole piece of evidence used to convict a person of a crimeSimply provides a link
