In the study, computer models, fossil records and information from living mammals revealed that most of the surviving mammals did not rely on trees, though the few arboreal mammals that lived on – including human ancestors – may have been versatile enough to adapt to the loss of trees
Many lakes and ponds are changing colors – from pleasant blue or clear to murky brown or green, caused by runoff of nutrients and carbon, coupled with warmer temperatures. A new global study of lakes finds that these relationships are much more complex, interrelated and nonlinear.
Awards that recognize excellence represented within the graduate community and celebrate student accomplishments; they honor members of the community who have demonstrated leadership and commitment to advancing efforts around diversity, inclusion, outreach and student engagement.
In the Department of Ecology and Evolutionary Biology (EEB) we value science and education grounded in the natural history of organisms, and have a desire to understand the patterns and processes that structure communities and ecosystems, and drive evolutionary change over all geographical and time scales. As new methods allow us to gain insight into ecological and evolutionary mechanism and function, we seek to refine fundamental concepts, to integrate findings into novel theory, and to contribute to solutions for environmental challenges. As a place of work, EEB is dynamic and friendly, committed to antiracism, and to be a safe space without harassment or discrimination of any sort, and to be as inclusive as possible (see our Diversity and Inclusion web page).
EEB faculty, students and staff pursue topics across a broad set of interlinked foci, including biogeochemistry and ecosystem science, community ecology and population biology, sustainability, environment and conservation, organismal biology, intimate organismal interactions and chemical ecology, evolutionary patterns and processes, and biological educational research.

During summer 2020, Drew Harvell, postdoc Lillian Aoki and Ph.D. student Olivia Graham traveled to the San Juan Islands off the coast of Washington state to study the pathogenic causes of seagrass wasting disease. Similar to how COVID-19 has swept through society, marine disease agents — like viruses, bacteria and protists — can have massive impacts that ripple through ecosystems. The triggers for epidemics in nature are just as complex, involving a combination of variables such as host stress, environmental conditions and changes in biological communities. Read "Hunting eelgrass disease in the San Juan Islands" for the full story.
“As a result of identity prejudice, certain individuals are more vulnerable to conflict and violence when they are in the field. It is paramount that all fieldworkers be informed of the risks some colleagues may face, so that they can define best practice together.” Amelia-Juliette Demery and Monique Pipkin: Safe fieldwork strategies for at-risk individuals, their supervisors and institutions.
