The Wilcove Team
(aka The Drongos)
David S. Wilcove (professor): Members of my research group use a combination of ecology, economics, and policy research to find innovative ways to protect biodiversity around the world. Recent or ongoing projects include: studies of the impact of logging and oil-palm agriculture on biodiversity in Southeast Asia; impact of the cage-bird trade on Indonesian birds; conservation of migratory animals; factors affecting the distribution of birds along elevational gradients in the Himalayas; reforestation and forest recovery in China, Costa Rica, and Peru; and the impacts of hunting on wildlife in China and Brazil. Prior to joining the Princeton faculty in 2001, I served as senior ecologist with the Environmental Defense Fund (1991-2001) and The Wilderness Society (1986-1991). I am an avid birdwatcher who cannot forgive himself for missing the Hawaiian Crow in 1996, but who did see the last wild Spix’s Macaw in Brazil in 1993.
Willandia Chaves (postdoc): I am a conservation biologist interested in working at the interface of wildlife ecology and the human dimensions of wildlife conservation, using tools and methods from different fields, including Conservation Psychology, Economics and Environmental Education among others. I am interested in assessing the impact of conservation actions on biodiversity and human well-being. For my postdoc, I am studying the illegal trade of freshwater turtles in the Brazilian Amazon. I am interested in assessing the impact of the trade on turtles and the social and economic factors influencing the trade. One of my goals is to identify priority actions and areas for turtle conservation in the region.
I completed my PhD and master's degrees in Interdisciplinary Ecology at the University of Florida and my bachelor's degree in Biological Sciences at the Federal University of Acre (Brazil). For my PhD, I assessed the factors influencing consumption of wild meat and implemented a social marketing campaign that successfully reduced wild meat consumption by urban residents in the central Amazon. For my master's, I assessed the effects of reduced impact logging on bird communities in the western Brazilian Amazon.
Dan Liang (postdoc): I am a field ecologist with broad interests in ecology, evolution, and conservation biology. My main research aims to understand how human-induced disturbances impact biodiversity. My PhD work looked at how urbanization affects stress responses and various levels of niche characteristics of passerine birds in subtropical environments in Southwest China. For my postdoc, I am working with Prof. David Wilcove to try to understand the effects of hunting or trapping on populations of birds, especially those birds migrate along the East Asian- Australasia Flyway.
Prior to Princeton, I received my PhD degree in Zoology from Sun Yat-sen University (2018), and received my master degree in Zoology (2015) and my bachelor degree in Wildlife and Nature Reserve Management (2012) from Southwest Forestry University in China.
Liang Ma (postdoc): Before I became a Drongo, I focused my research on understanding the relationship between thermal variation over space and time and the physiology and life history of ectotherms. I parameterized mechanistic models with reaction norms derived from empirical studies to generate new insights about the process of thermal adaptation at both local and global scales. Now, I am exploring how climate and land-use change will impact pikas in China. Specifically, I currently plan to answer this question from the perspectives of species distribution and physiological limitation, respectively.
From 2012 to 2019, I completed my PhD and did a postdoc with Wei-guo Du at the Institute of Zoology, Chinese Academy of Sciences. I received my BS from Beijing Forestry University in 2012. During 2015-2016, I did a one-year internship at the University of Washington (Seattle) with Lauren B. Buckley and Raymond B. Huey.
Rebecca Senior (postdoc): I am a conservation biologist interested in exploring ecological patterns across scales to inform pragmatic and adaptable conservation practices. I have a particular interest in using advances in technology and open data to tackle difficult questions, and am an avid R user. If you'd like to know more see my personal website: https://rebeccasenior.netlify.com/.
For my postdoctoral research I am assessing the effectiveness of different conservation strategies for recovering threatened species. Before arriving in Princeton I completed my PhD at the University of Sheffield (UK), where I studied how loss and degradation of tropical forest impacts species’ ability to cope with global climate change. Prior to that I worked at UNEP-WCMC, mainly on the PREDICTS project, and I completed my undergraduate studies at the University of Cambridge (UK).
Umesh Srinivasan (postdoc): My primary research interests lie in understanding how various forms of human-induced forest conversion impact biodiversity. My PhD looked at how selective logging affects the demography of understorey insectivorous birds in the Eastern Himalaya. My other research areas have been in trying to unravel how multiple species associate with each other on mixed-species bird flocks, and in biogeography, especially the biogeography of the Himalayan mountain range.
I received a PhD from the National Centre for Biological Sciences in India, before which I completed by Master's in Wildlife Biology and Conservation from the WCS-India, Centre for Wildlife Studies and NCBS programme in Bangalore. In a previous life, I was also trained as a medical doctor.
Christopher Crawford (graduate student): Some of my research interests include ecological restoration (particularly along rivers and streams), incentives for conservation and restoration on private lands, the effects of agricultural land use on biodiversity, and causes and consequences of land use change. Big questions include: how do we find more room for biodiversity in human-dominated landscapes, and how do we feed the world without destroying it? By exploring the biodiversity, ecosystem service, and economic trade-offs of different land use scenarios, and looking at policies and incentives to effectively guide land use, I hope to improve how we use land for conservation and for people.
Prior to graduate school, I spent 3.5 years working for Sustainable Conservation in San Francisco, on collaborative projects to 1) reduce the use of invasive plants in horticulture (PlantRight) and 2) facilitate riparian restoration in California’s Central Valley. I graduated from the University of Michigan in 2012, and I love riding my bicycle, taking pictures of clouds, and listening to Swedish music.
Tong Mu (graduate student): My research interests lie in the field of avian ecology and conservation, especially that of shorebirds migrating along the East Asian-Australasian Flyway. Combining field study, individual tracking and mathematical modeling, I plan to identify the factors affecting their selections of migration routes and stopover sites, and to see whether the understanding of shorebirds migration patterns can be extended to that of other migratory birds.
Prior to joining the Drongos, I received my B.S. from Peking University in 2014, and during my time there, I became an avid birdwatcher and also became aware of the conservation issues pertaining to birds and other organisms.
March 14, 2018: Another rare sighting of all of the Drongos in the same place at the same time.
On a cold day in March 2014, all of the Drongos were together in Princeton for the first time in over a year. Todd Reichart (Chemistry Department) took this historic photo to commemorate the event.
This photo from February 2013 represents a rare occasion when all of the Drongos were together at the same time on the Princeton Campus. Usually at least one of us is in Indonesia, Malaysia, Brunei, China, India, Korea, Peru, Ecuador, or even Tennessee.
