We study the patterns and predictors of biodiversity across environmental gradients. We work mostly with plants and pollinators in temperate and tropical forests. Our field sites span from temperate deciduous forests in the eastern United States to tropical forests of Central and South America.
Dr. Hulshof is a tropical ecologist. She studies patterns of diversity across space from tropical to temperate latitudes and through time as ecosystems respond to long-term disturbances like climate change.
Allyson is a Master’s student at Virginia Commonwealth University. She is studying plant and pollinator diversity in a serpentine savanna in the eastern United States and the effects of disturbance and recovery of plant and pollinator communities post deer-exclusion.
Ramon is an ecologist trained in Puerto Rico. His expertise of the flora and fauna of the island keeps our lab and field projects functioning smoothly.
Luis participated in the Luquillo LTER NSF-REU program Puerto Rico and investigated the diversity and distribution of butterflies. He is now continuing an independent research project in the lab relating species distribution models and phenotypic variation of butterflies.
Mariangeli has been working in the lab on an independent research project relating phenotypic variation of wing color and size in the non-migratory Puerto Rican monarch in montane and coastal regions. She also made important contributions to our large Puerto Rican Lepidoptera Digitization project.
Dayneris studied the effects of low oxygen levels on benthic macrofauna in the bay of Cienfuegos, Cuba before beginning her Master’s at UPR-Mayagüez. She is now studying the effects of Hurricane Maria on the recovery and resilience of butterfly populations in Puerto Rico.
Claudia previously worked in the páramo of Colombia before beginning her Master’s at the UPR-Mayagüez. She is studying plant functional diversity of serpentine soils across mountains in Puerto Rico to better understand how these unique systems may be affected by ongoing and future climate change.
Mountains are among the most biodiverse places on Earth, provide freshwater for half of all humans, and are priority regions for conservation.
Our understanding of the structure and functioning of unusual soil systems is based on small plot research primarily from temperate regions. We are working towards the first regional synthesis of tropical serpentine flora diversity.
Puerto Rico is a tiny but topographically complex island which provides a backdrop for determining how plant-herbivore interactions are shaped by soil and climate at small spatial scales.
Hispanics are the largest growing population group in the United States. The number of Hispanic (and more broadly, Minority) Serving Institutions is on the rise and, according to the Hispanic Association of Colleges & Universities, doesn’t appear to be slowing down.…
We know standardized test scores aren’t strong predictors of success. So why do we still require them? I have been a vocal advocate for eliminating the GRE requirement for our Master’s program. And here’s why.
Vanilla doesn’t come to mind when you think of Puerto Rico. Yet the history of vanilla is intricately tied to the history of the island.
