Her research spans from freshwater ecosystems to complex microbial consortia such as gut microbiota and synthetic algae communities. Litchman has been recognized with prestigious accolades including the Presidential Early Career Award for Scientists and Engineers, affirming her influence in microbial ecology and biogeochemical cycling studies.
Ecosystem scientist Dennis S. Ojima of Colorado State University leads research on global change effects in drylands and other ecosystems, emphasizing social-ecological adaptation frameworks. His work contributes directly to international environmental assessments, including the Millennium Ecosystem Assessment and the Intergovernmental Panel on Climate Change, recognized globally with the 2007 Nobel Peace Prize. Ojima’s blend of ecosystem science and policy engagement exemplifies ecological research’s role in addressing planetary-scale environmental challenges.
Jason R. Rohr of the University of Notre Dame stands at the nexus of ecology and public health, exploring how environmental perturbations alter wildlife disease dynamics with implications for zoonotic disease emergence. His focus on pollutants, climate change, and biodiversity loss informs strategies for mitigating health risks and promoting ecosystem sustainability. Rohr’s integrative research underscores ecology’s vital contribution to understanding intertwined human and environmental health issues.
University of Nevada, Reno’s C. Richard Tracy is a biologist whose career spans physiology, ecology, and conservation biology. Beyond his diverse research portfolio, Tracy’s mentorship and educational leadership have shaped generations of ecologists. His recognition by institutions such as the Guggenheim Foundation and the American Association for the Advancement of Science speaks to his enduring scholarly influence and commitment to academic excellence.
The Early Career Fellows elected in 2025 represent the vanguard of ecological science, embracing multifaceted approaches to address critical environmental issues. Sarah M. Anderson’s landscape ecology work operationalizes ecosystem-based management within the U.S. Forest Service, utilizing complex assessments like the Terrestrial Condition Assessment to inform national reforestation strategies. Her mentorship and policy experience illustrate the translational potential of ecological expertise within governmental frameworks.
Daniel J. Becker at the University of Oklahoma interrogates the ecology of infectious diseases, focusing on zoonotic pathogen spillover via ecological immunology and predictive analytics. His research has direct implications for pandemic prevention, as highlighted by his leadership roles in commissions dedicated to viral spillover mitigation. Becker’s approach exemplifies the ecological lens on global health security challenges amplified by environmental change.
Joanna R. Bernhardt of the University of Guelph integrates theoretical and empirical research to unravel biodiversity dynamics and their consequences for human well-being. Through metabolic theory and ecological frameworks, she advances understanding of how energy and matter fluxes underpin living systems’ responses to environmental variability. Bernhardt’s synthesis of ecological processes informs conservation and sustainability efforts critical to addressing global biodiversity loss.
Joan C. Dudney, Assistant Professor at the University of California, Santa Barbara, employs big data synthesis and long-term ecological research to dissect interactions among disturbances like fire, drought, and disease that reshape forest ecosystems. Her quantitative innovations untangle complex climate-ecosystem feedbacks, directly influencing conservation policies that seek to enhance forest resilience in an era of escalating global change.
Benjamin G. Freeman’s Mountain Bird Network and lab at Georgia Tech investigate species distribution patterns and range shifts in response to climate variability. By compiling global systematic surveys, Freeman’s research elucidates fundamental ecological and evolutionary questions related to avian biology, enhancing predictive understanding of biodiversity responses to environmental stressors.
