w9 palynology Flashcards
what can pollen tell us?
- honey production
- archaeological applications
- geological applications
what is pollen?
produced by seed-producing plants i.e. flowers or cones
carry male gametes of flowering plants
what are spores
asexual reproductive bodies
produced by non-reprodcutive plants
what are the four principles of pollen analysis
distinct morphology of pollen grains
extremely resistant to decay
produced in vast quantities
widely dispersed
pollen morphology
how long does pollen last
how is pollen recorded
grains per cubic meter
we inhale around 10m3 per day
how will pollen travel great distances
- wind (most common)
- insects or birds (travel shorter distance)
- water (wetland species)
what is a pollen prints
areas that have a unique pollen (almost like a fingerprint) for that specific area only
what are the four stages of sample analysis
collection
processing
identification
analysis
what is the significance of pollen evidence
linked to the pollen type observed and knowledge of the scenes
need to have a background of pollen assemblages and dispersal patterns
studies in t the transfer and persistence of pollen
evidence can be assessed using likelihood ratio
what is forensic entomology
study of insects associated with a human corpse in criminal investigations
