Taking nature's pulse
… to the often-forgotten sense of hearing. The Tropical Ecology Lab at University of Puerto Rico, San Piedras, blurs the lines between natural history and science. An array of remote microphones collects sounds from the forests and wetlands, and researchers use computers to analyze the …

Beyond the Biological: William Beebe, the Bronx Zoo, and U.S. Biological Field Stations in British Guiana
<p>The Department of Tropical Research (the DTR) was created in 1916 by William Beebe, an ornithologist working for the New York Zoological Society, in British Guiana as a branch of the newly opened Bronx Zoo in New York. It was the first biological laboratory set up in the tropics connected to a …

Seed predation along an elevational gradient in the Tropical Andes, Peru
… seed predation study of 24 species of tropical trees across a 2.5 km elevation gradient in the Peruvian Andes. The following questions were asked (1) does seed predation vary across the elevation gradient? (2) do predation rates vary among species and are those rates predictable from …

What’s in a Tooth? Signals of Ecogeography and Phylogeny in the Dentition of Macaques (Cercopithecidae: Macaca)
… To this end, the relationship between geography, ecology, phylogeny, and phenotypic variation among macaques was investigated. Constraints to phenotypic variation – and thus evolution – were also analysed in the form of observed amounts of phenotypic variation and patterns of phenotypic …

A camera trap assessment of factors influencing leopard (Panthera pardus) habitat use in the Nouabalé-Ndoki National Park, Republic of Congo
… camera trap array that forms part of the Tropical Ecology, Assessment and Monitoring (TEAM) project - Terrestrial Vertebrate (Camera Trapping) Monitoring Protocol, to estimate the species richness of mammals, the relative abundance of leopard prey species and leopard habitat use in the …

A snapshot of color: Exploring the ecological and genetic basis of color variation in the Neotropical tortoise beetle, Chelymorpha alternans (chrysomelidae:cassidinae)
… 1) What is the geographic distribution of the Neotropical tortoise beetle, Chelymorpha alternans, across the Isthmus of Panama? 2) What is the inheritance hierarchy of alleles for color polymorphisms in Chelymorpha alternans? 3) Do mating preferences for particular color morphs influence the …

Understanding tropical forest dynamics through remote sensing and deep learning
Protection of tropical forests is key to achieving global climate and biodiversity conservation goals. They play an essential role in carbon sequestration, water cycling, and nutrient exchanges, thereby regulating atmospheric composition and global climate patterns. However, they are under …

Understanding the role of plant hydraulic traits in ecological processes
Among all ecosystems tropical forests play a disproportionate role in Earth’s carbon cycle as they account for one third of total primary productivity. Global environmental change is causing novel precipitation patterns, shifts in the timing of rainfall events and an increase of the atmospheric …

Geological Control of Floristic Composition in Amazonian Forests
… the largest remaining tracts of undisturbed tropical forest on earth, and is thus critical to international nature conservation and carbon sequestration efforts. Amazonian forests are notoriously difficult to study, however, due to their species richness and inaccessibility. This has limited …
