Jesse R. Lasky, Assistant Professor of Biology at Penn State, presented
“The Effects of the Geometry of Environment on Diversity.”
He found inspiration in the travels of Alexander von Humboldt in South
America, where Humboldt observed the greater biodiversity of tropics
and mapped elevation gradients.
This talk included highlights from three research projects. One study
researched the effect of pastureland on seed dispersal among
frugivorous birds in Para, Brazil. He found that trees with large
crowns standing in pastures were likely to attract birds from the
nearby forest fragments.
A second project was located in dry forest in Panama, the home of
highly threatened bird communities. The amount of forest cover and the
distance from forest edges did not seem to affect bird distribution,
possibly because the forest is already so fragmented that most of the
forest specialty birds have already vacated.
The third project revealed that the U.S.-Mexico border fence interferes
with animal dispersal, particularly impacting endemic species with
small ranges in mountain and coast areas.
