Functional analysis of secondary tropical dry forests in a region of the Colombia, Caribbean
Secondary tropical forests are increasingly recognized for their role conserving biodiversity in agricultural landscapes and this role is especially important for seasonally dry tropical forests (SDTF), one of the most threatened tropical forested ecosystems. The conservation value of secondary …

Primate-Plant Interactions in the Tropical Dry Forests of Northwestern Madagascar: Seed Dispersal and Sensory Ecology of Eulemur fulvus.
… and the endemic fruits they disperse in the tropical dry forests of Ankarafantsika National Park, northwestern Madagascar. I analyze fruit traits across all fruits consumed by brown lemurs over the course of one year of behavioral study of three groups of habituated, individually identifiable …

Impact of human land-use and rainfall variability in tropical dry forests of southwest Madagascar during the late Holocene
… Madagascar is semi-arid and comprises fragmented tropical dry forests where human subsistence strategies are diverse. Therefore, it provides a perfect setting to generate new palaeoecological records and investigate vegetation response to changes in human land-use and rainfall variability. The aim …

Carbon cycling in secondary tropical dry forest from species to global scales.
Tropical forests are important in the global carbon cycle but questions remain about the distribution of carbon stocks and the controls over carbon cycle processes in these forests. This is especially true with tropical dry forests which comprise as much as 43% of global tropical forests, but have …

Elevational Gradients Shape Bee Network Structure and Community Composition Across Tropical Lowland to Montane Forests in Costa Rica
… in smallholder farms in three life zones: tropical dry forests, premontane forests, and montane forests in the mountains of Costa Rica. Results revealed a marginally significant decreasing relationship between elevation and network specialization. Connectance and modularity both …

Fantastic Birds and Where to Find Them
… United States to the riparian areas in tropical dry forests along the Pacific coast of Central America. The predictive model of potential habitat suitability will be corroborated on the ground by conservation collaborators and used to locate new long-term monitoring sites, and acquire …

Thermal and Behavioral Ecology of the Mexican Beaded Lizard (Heloderma horridum)
… that are not as strongly seasonal as the tropical dry forests found along the Pacific Coast of Jalisco, Mexico. Small organisms have little or no appreciable thermal inertia, and thus, reach thermal equilibrium with their immediate surroundings relatively rapidly. In this investigation, we …

Interactions among tree species and pathogen-suppressive bacteria in tropical forest soils
In tropical forests, soil-borne plant pathogens are thought to regulate diversity by driving negative plant-soil feedbacks and promoting density-dependent mortality of seedlings close to parent trees. Pathogens interact with a myriad of other organisms in soil that have the potential to moderate …

A 1000-year sedimentary record of hurricane, fire, and vegetation history from a coastal lagoon in southwestern Dominican Republic
… and the patterns and role of fire in Caribbean dry forests are lacking. This project combines paleoecological and paleotempestological methods to document the disturbance and environmental history of the last 1000 yrs at Laguna Alejandro, situated in the lowland dry forests of arid SW Dominican …

Evaluating dry woodlands degradation and on-farm tee management in kenyan drylands
Tropical dry forests and woodlands are comprised of trees that are specially adapted to the harsh climatic and edaphic conditions, providing important ecosystem services for communities in an environment where other types of tropical tree species would not survive. Due to cyclic droughts which …

Effects of fragmentation and invasion on ant communities
… characteristics are especially problematic in tropical ecosystems where nutrient-poor soils do not easily meet the agricultural demands of growing human populations. A consequence of replacing tropical forests with agriculture is the creation of landscapes consisting of fragments of natural …
