The extent of travel can depend on pzlynology variety of factors including the strength and direction of the wind, the weight and shape of the grain, and atmospheric conditions, though the pollen will typically fall within around 2km of the parent plant.

Palynology Forensic disciplines Forensic palynology. If a suspect was present at a particular crime scene at which pollen can be found for instance a field or gardenthey may have picked up pollen on their clothing or in their hair. His body could not be found.

All of these features make them especially ideal for use in a forensic investigation. Pollen and Spores Pollen refers to a powder containing the male gametophytes of seed-producing plants, produced and dispersed in order to pollinate and reproduce.

From Wikipedia, the free encyclopedia. Civil and criminal investigations.

The morphology of pollen and similar substances is fairly complex, meaning that with the appropriate equipment, expertise and reference materials, it is possible to distinguish between and identify pollen grains. In addition to this, scanning electron microscopy SEM may be utilised. The defendant was confronted with this new piece of information, at which point he finally cracked and confessed to the murder.

Pollen grains are dispersed in a variety of ways. Pollen and spores provide clues as to the source of the items and the characteristics of the environments from which the forfnsic on them is sourced. Pollen recovered from a suspect that happens to match that of a crime scene may simply suggest that the individual had visited that area at some point recently, not necessarily prove that they have committed a crime.

The use of spores and pollen. Of course despite the links palynology may establish, further evidence may be needed to support any conclusions reached.

Forensic palynology: why do it and how it works.

With so many publications and high-profile cases involving forensic palynology and environmental analysis now receiving publicity, the future of this branch of forensic science is assured. Why do it and how it works. Finally, autogamous plants are self-pollinating, so the pollen they produce does not need to travel.

For instance, it may be possible to link a suspect to an object, a vehicle to a crime scene, or even link two separate incident scenes.
