The breeding structure of a tropical keystone plant resource

Article Abstract:

The question of what constitutes effective breeding units of keystone plat resources in tropical wildlife parks and forested preserve, has not been addressed directly. Paternity analysis techniques were used to reconstruct the genotypes of pollen donor trees and estimate pollen dispersal distances and breeding population size in Panamanian populations of monoecious strangler figs. Pollen dispersal occurred routinely over estimated distances of 5.8-14.2km, thus breeding units consisted of many intermating individuals.

Long-distance transport of pollen into the Arctic

Article Abstract:

In the Canadian Arctic in June 1998, significant amounts of pine and spruce pollen were transported roughly 3,000 km, possibly the result of an unusually strong low-pressure system over Repulse Bay. The pollen may have been lifted into the air by high surface winds and the mass travelled northest over Labrador, north over the Labrador Sea and west over southern Baffin Island, arriving at Repulse Bay. Similar rare transport events may account for noise in ice-core records of pollen.

Pollen analysis reveals murder season

Article Abstract:

Pollen analysis is an underused resource in forensic science and has only once been used to investigate a reported case of murder. An experiment used pollen analysis to determine time of death, following examinations of a common grave containing 32 murder victims. It was established that the murders must have happened in the summer of an unknown year, and concluded that the victims were Soviet soldiers, using a method of pollen analysis developed by Erdtmann and Faegri.
