The sugar composition of fruits in the diet of spider monkeys (Ateles geoffroyi) in tropical humid forest in Costa Rica [PDF]

open access: yes, 2003
Spider monkeys (Ateles geoffroyi) detect sucrose at a threshold lower than any primate yet tested and prefer sucrose to glucose or fructose in laboratory tests.

Nickel hyperaccumulation in Orthion and Mayanaea (Violaceae) from Mesoamerica

open access: yesEcological Research, Volume 39, Issue 6, Page 879-893, November 2024.
This article reports the discovery that seven species of woody plants (pictured) in the genera Orthion and Mayanaea (Violaceae) are capable of hyperaccumulating nickel (Ni) in their leaves, and many individuals simultaneously hyperaccumulate cobalt as well.

Patterns in the genetic structure of 49 lowland rain forest tree species co‐distributed on opposite sides of the northern Andes

open access: yesBiotropica, Volume 56, Issue 2, March 2024.
The northern Andes are a major biogeographic dispersal barrier to lowland rain forest trees. We examine genetic diversity and divergence of paired populations of 49 rain forest tree species co‐distributed on opposite sides of the Andes and show that dispersal across or around this biogeographic barrier has left enduring genetic signatures.

Lidar-Based Models of Understory Bird Habitat in a Tropical Forest [PDF]

open access: yes, 2011
Where a poorly understood group of wildlife species seems to be declining quickly, a rapid assessment of the species’ habitat requirements may be needed in order to make the most optimal management decisions possible.

Seed‐to‐Seedling Transitions Exhibit Distance‐Dependent Mortality but No Strong Spacing Effects in a Neotropical Forest [PDF]

open access: yes, 2019
Patterns of seed dispersal and seed mortality influence the spatial structure of plant communities and the local coexistence of competing species. Most seeds are dispersed in proximity to the parent tree, where mortality is also expected to be the ...
