New Perspectives on TransOceanic Dispersal, Guided by a Critically Endangered Group of Tropical Plants: Hibiscus sect. Lilibiscus

Mashburn seeks to understand how Hibiscus sect. Lilibiscus achieved biogeographical distribution. Mashburn’s preliminary work suggests that Madagascar played an important role in the evolutionary history of the clade, and field work will allow sampling from the island. Species’ boundaries will be clarified and phylogenetic relationships among the six Madagascar species will be reconstructed. Data will solidify an understanding of the little-known biogeographic pattern and provide insight into mechanisms of extreme long-distance dispersal around the globe. The project will contribute to the first steps of conserving the six species in Madagascar.

Biodiversity Discovery and Monitoring of Fungi in Cusuco National Park, Honduras

Stallman’s incidental collection of Helotiales and plot-based sampling of all macroscopic fungi will take place in Cusuco National Park, Honduras. Field research will provide insight on how macrofungal populations change among different elevations, vegetation types, and other environmental correlates. By determining how fungal species richness relates to biotic and abiotic factors, priorities can be made for future conservation and biodiversity discovery studies.

Consequences of Disturbance on Plant-Lemur Networks in Madagascar

To better understand complex plant-lemur interaction networks critical for restoring a healthy ecosystem in Madagascar’s forest landscapes, DeSisto will conduct botanical research and outreach in COMATSA, a protected area connecting two hyperdiverse national parks. Botanical and lemur surveys, local ecological knowledge, and population and network modeling combined with robust community outreach will promote tropical conservation. Results from building multilayer ethnoecological networks will advance botanical conservation in a highly threatened rainforest landscape that provides critical resources for over 200 tree species, nine lemur species, and numerous human communities.

Patterns of Diversification and Gene Flow in Andean Prunus

Quinlan seeks to advance understanding of the origin, maintenance, and coexistence of neotropical tree biodiversity and inform conservation by characterizing patterns of diversification, genetic diversity, and gene flow among congeneric Andean trees. Studying Prunus in the Kosñipata Valley within Manu National Park, Peru, will allow Quinlan to characterize the phylogenetic relationships among Prunus species, assess genetic structure among altitudinal populations, and test for gene flow among co-occurring species.

Longitudinal Study to Test for the Acclimation of Individual Trees to Multiple Decades of Climate Change 

Fortier will leverage long-term plot data and associated herbarium specimens to investigate how individual tropical trees in the Peruvian Amazon have acclimated to climate change over the last 40-plus years. Changes in functional traits of individual plants over multiple years will be examined. Fortier’s research will help predict future changes in Amazon tree composition and may target species in greater need of conservation initiatives.

Can Branch Architecture from Laser Scans Predict Tree Growth Rates in Neotropical Dry Forests?

Using a collection of twigs from tropical dry-forest species, Chmurzynski will analyze models of tree growth and validate laser scanning methods. Chmurzynski will use remote-sensing data to test fundamental ecological theories at the interface of plant ecology and global change. In addition, Chmurzynski will apply 3D laser scanning technology to quantify the geometry of tree branches as well as wholeplant form and function. Findings will provide models of tree growth to better predict changes in forested landscapes over time.
