Human impacts on the environment are having an important effect on biodiversity. Climate change, population growth, urban expansion, food production, and changing land use are altering ecosystems in profound ways. Biodiversity is critical for Earth’s ecosystems and for human life.
Our faculty, postdocs, and students seek to study and understand the specific impacts that environmental changes, such as habitat loss and global warming, are having on species and ecosystems. Drawing on this information, they work alongside policymakers, NGOs, and other research collaborators to help identify the best strategies for protecting biodiversity, improving outcomes for endangered species, and sustaining the natural resources required for future generations.
More specifically, recent research in this area has covered such topics as forest conversion and logging, oil-palm production, the unsustainable trapping of wild animals, reforestation and other forms of ecological restoration, animal migration patterns, and agricultural land use. Their research methods and approaches encompass both ecology and the social sciences.

Climate change poses a tremendous challenge to biodiversity conservation. Species' vulnerability to climate change depends on many factors, such as their physiology, dispersal ability, and current ranges. Our researchers are studying how climate change is affecting particular species and making projections for potential future impacts as global average temperatures continue to rise.
Populations of migratory animals are in decline around the world. Four key, human-caused threats are widely recognized as the major drivers of past and current declines: habitat loss, overexploitation, interruption of migratory pathways, and climate change. Our researchers are mapping the detailed foraging patterns of different shorebird species at stopover sites, identifying the priority areas for conservation and more broadly tracking migration patterns and changes at the global scale.
The trapping of wild animals for use as either food, products, or pets is one way that wildlife may be exploited and put at risk of extinction through human actions. As more people are moving from rural to urban areas, our researchers are investigating how this pattern of mass migration may affect species, particularly looking at how rural-to-urban migration affects the consumption rates of wild meat.
The most comprehensive assessment of biodiversity to date recently estimated that roughly 1 million species may be threatened with extinction. This is unprecedented within human history, and such a loss of species could have seriously detrimental consequences for human well-being. Our researchers are rigorously examining the actions that actually improve the survival prospects of imperiled species to help better allocate limited resources and to maximize the benefits for biodiversity.
