NEVO SAGI
BARD Postdoctoral Fellow
Nevo is fascinated by the workings of ecosystems and devote my research to unraveling their complexities. His work integrates concepts and methods from both community and ecosystem ecology, with a particular focus on zoogeochemistry—the role of animals in biogeochemical cycles under varying environmental conditions. He is currently investigating how interactions between large herbivores and soil fauna influence carbon dynamics along a broad aridity gradient across Texas rangelands. This research aims to uncover the mechanisms driving these processes and to understand their implications for carbon cycling and ecosystem health in a changing climate.

JULIA BERLINER
PhD student
Julia earned her MS in Entomology at the University of Georgia, where she studied how insect
herbivores and predators respond to soil nutrient availability depending on their diet breadth.
She is fascinated by how biogeochemical cycles ubiquitously shape ecosystems by governing
community composition and trophic interactions. She is currently a third year PhD student,
where she is studying how human activities mediate the nutritional quality and community
composition of shorebird invertebrate prey, with the goal of helping to inform shorebird
conservation in the Arctic and the Texas Gulf Coast.

ANNIE CRESS
PhD student
Annie is a third year PhD student interested in untangling the ways both living organisms and
environmental conditions shape ecological processes. She is especially curious about the ways food
webs and community interactions drive ecosystem functioning. Currently, using wild, white-footed
deer mice and their helminth parasites as a model system, she is exploring how sublethal infections
shape the condition, diet, microbiome, and behavior of this widespread wild species. When she isn’t
linking small organisms to large ecosystem level processes, she enjoys playing pickleball, spending
time with friends, and introducing children to the fascinating world of ecology through outreach!
