Eminent Ecologist Award
Juan Carlos Castilla, Emeritus Professor, Department of Ecology, Pontifical Catholic University of Chile

The Eminent Ecologist Award honors a senior ecologist for an outstanding body of ecological work or sustained ecological contributions of extraordinary merit. This year’s Eminent Ecologist Award goes to renowned ecologist Juan Carlos Castilla.

A prominent figure in marine ecology and a pioneer of coastal resource management, Castilla has profoundly influenced both the scientific community and environmental policy in Chile. His research on human impacts on Chilean coastal ecosystems and his work promoting sustainable resource use have reshaped global approaches to coastal zone management and conservation.

Spanning decades, Castilla’s research demonstrates the critical role of keystone species in rocky intertidal and marine ecosystems, and how humans serve as super-keystones in these settings. A co-founder of the Pontifical Catholic University of Chile’s Coastal Marine Research Station at Las Cruces, one of the country’s first no-take marine research facilities, Castilla gained early recognition for his work showing how benthic shellfish harvesting by humans had fundamentally restructured the region’s coastal ecosystems. Since then, his work to understand the structure and dynamics of coastal communities continues, with a growing focus on conservation, resource management and outreach. His scientific insights underpin the development of marine protected areas, in Chile and elsewhere.

One of Castilla’s greatest achievements is working collaboratively with local fisher communities that serves as a model for science-informed, community-based management of marine resources. His meticulous study of the unique Chilean muricid mollusk known as the “loco” and its fishery’s collapse in the 1980s led to the establishment of Chile’s first Management and Exploitation Area for Benthic Resources. These preserves—co-managed by artisanal fishers and the Chilean government, with input from scientists—grant fishers exclusive access to benthic coastal resources, thereby empowering local communities to steward their resources effectively. Castilla’s innovative engagement with local knowledge-holders forged unprecedented alliances between scientists, policymakers and stakeholders. By fostering dialogue and collaboration, he has continued to spearhead legislative reforms that advance sustainable resource management practices.

Castilla’s contributions have earned him prestigious accolades, including the BBVA Foundation Award, the Mexico Prize for Science and Technology, the Ramon Margalef Prize, the Chile National Prize in Science and Technology and membership in institutions like the U.S. National Academy of Sciences and the Third World Academy of Sciences. Beyond his scientific accolades, Dr. Castilla’s enduring legacy is exemplified by his mentorship and advocacy, nurturing a generation of environmental leaders who continue to shape the trajectory of ecological research and policy worldwide.

George Mercer Award
Megan L. Vahsen, Michael J. Blum, J. Patrick Megonigal, Scott J. Emrich, James R. Holmquist, Brady Stiller, Kathe E. O. Todd-Brown and Jason S. McLachlan

ESA presents the 2024 George Mercer Award to the authors of “Rapid plant trait evolution can alter coastal wetland resilience to sea level rise,” published in Science Jan. 26, 2023.

The George Mercer Award was established in 1948 and is given annually for an outstanding ecological research paper published within the past two years with an early-career lead author.

This study calls attention to the significant, yet often overlooked, role of rapid evolution in shaping how ecosystems respond to global change. Examining a dominant coastal marsh sedge, the research reveals how genetically-based variation in a plant’s traits—specifically traits affecting root growth—can evolve rapidly and influence a marsh’s resilience to sea level rise.

The research team used a unique approach, growing “resurrected” plants from decades-old seeds recovered from marsh soils and employing an ecosystem modeling approach to demonstrate that genetic variation observed among the plants and rapid evolution can affect the ecosystem’s ability to store carbon and build soil elevation. In turn, these functions directly impact the wetland’s capacity to keep pace with rising sea levels, a key factor in its long-term persistence.

Bridging quantitative genetics and ecosystem modeling, this study highlights the need to consider evolutionary processes in ecological forecasting. The paper’s innovative use of historical seed samples, genetic methods and simulation models advance our understanding of the interplay between evolutionary and ecosystem-level responses to anthropogenic change.

 

W.S. Cooper Award
M. Brooke Rose, Santiago José Elías Velazco, Helen M. Regan and Janet Franklin

The Cooper Award honors the authors of an outstanding publication in the field of geobotany, physiographic ecology, plant succession or the distribution of plants along environmental gradients. William S. Cooper was a pioneer of physiographic ecology and geobotany, with a particular interest in the influence of historical factors—such as glaciations and climate history—on the pattern of contemporary plant communities.

This year’s Cooper Award goes to the authors of “Rarity, geography, and plant exposure to global change in the California Floristic Province,” published in Global Ecology and Biogeography Dec. 5, 2022.

Analyzing the ranges of over 100 species of plants, this study provides a crucial analysis of how a plant’s rarity and geography affect its vulnerability to climate and land use changes. Applying different climate and land use scenarios to species distribution models, the research examines plants’ exposure to recent (1980–2010) and future (2070–2099) anthropogenic changes.

The findings reveal that rare species, such as those with smaller ranges, are particularly susceptible to climate change impacts. However, for predicting a plant’s susceptibility to land use change, geography—not rarity—is a better predictor. The intertwined nature of rarity and geography underscores the importance of incorporating both of these factors into conservation strategies.

The work is a significant extension of William S. Cooper’s legacy, using advanced predictive models to further our understanding of plant distributions and their responses to environmental changes.

 

Sustainability Science Award
Jason Rohr, Alexandra E. Sack, Sidy Bakhoum, Christopher B. Barrett, David Lopez-Carr, Andrew J. Chamberlin, David J. Civitello, Cledor Diatta, Molly J. Doruska, Giulio De Leo, Christopher J. E. Haggerty, Isabel J. Jones, Nicolas Jouanard, Andrea J. Lund, Amadou T. Ly, Raphael A. Ndione, Justin V. Remais, Gilles Riveau, Anne-Marie Schacht, Momy Seck Ndao, Simon Senghor, Susanne Helene Sokolow and Caitlin Wolfe

An international team of biologists, social scientists and medical researchers from the United States and Senegal is the recipient of the 2024 Sustainability Science Award for a study that offers a win-win solution for addressing food and water access, poverty alleviation, disease control and environmental degradation in West Africa.

The Sustainability Science Award recognizes the authors of the scholarly work that makes the greatest contribution to the emerging science of ecosystem and regional sustainability through the integration of ecological and social sciences.

“A planetary health innovation for disease, food and water challenges in Africa,” by corresponding author Jason Rohr and 22 other researchers, was published in Nature July 12, 2023. The study presents a strategy for managing the parasitic disease schistosomiasis, which affects millions globally, by addressing the environmental conditions that foster its spread.

The team conducted a randomized controlled trial in Senegal, removing invasive freshwater plants that restricted water access for local villages and served as habitat for disease-transmitting snails. The experiment not only reduced disease rates but also generated large amounts of plant material that could be repurposed as cheap livestock feed and compost, enhancing agricultural productivity and economic outcomes for local communities.

By turning a public health hazard into a valuable resource, the research demonstrates a scalable solution that benefits both human health and the environment. Furthermore, it showcases the power of integrating scientific research with community engagement—local participation was pivotal to the project’s success. The work stands as a prime example of how sustainable practices can significantly improve wealth, health, food and water access simultaneously, embodying the principles of sustainability science and offering a model for global ecological and social challenges.

 

Forrest Shreve Research Award
Benjy Sedano-Herrera, M.S. student, School of Life Sciences, University of Nevada Las Vegas

Forrest Shreve was an internationally known American botanist devoted to the study of the distribution of vegetation as determined by soil and climate conditions, with a focus on desert vegetation. The Forrest Shreve Research Award supplies $1,000–2,000 to support ecological research by graduate or undergraduate student members of ESA in the hot deserts of North America (Sonora, Mohave, Chihuahua and Vizcaino).

Benjy Sedano-Herrera was selected to receive this year’s Forrest Shreve Student Research Award for his work investigating biological soil crusts in the Mojave and Chihuahuan Deserts.

Sedano-Herrera’s research focuses on cyanobacteria that colonize bare soils in arid regions, forming soil crusts. Through the production of exopolysaccharides (long, sugar-based molecules that clump together), cyanobacteria play a vital role in soil stabilization, fertility and water retention. These crucial functions boost survival of desert plants and the organisms that depend on them.

Examining two different soil types, Sedano-Herrera is testing how the availability of phosphorus, an essential nutrient that is scarce in desert soils, affects cyanobacterial growth and their production of exopolysaccharides. His work will deepen our understanding of desert soil ecology and contribute to potential strategies for improving dryland soil health.

 

2023 Annual Meeting Student Awards

Murray F. Buell Award for Excellence in Ecology
Jacob Levine, Ph.D. student, Department of Ecology and Evolutionary Biology, Princeton University

Murray F. Buell had a long and distinguished record of service and accomplishment in the Ecological Society of America, and he ascribed great importance to the participation of students in meetings and to excellence in the presentation of papers.

This year’s Murray F. Buell Award for Excellence in Ecology, which is awarded to a student each year for an outstanding oral paper presented at the ESA Annual Meeting, goes to Jacob Levine for his presentation at the 2023 Annual Meeting titled, “Competition for time: rethinking species interactions to understand the impacts of climate change on biodiversity.”

Levine’s research introduces the concept of “competition for time,” which suggests that competition between plants for scarce resources can reduce the amount of time the competitors have to grow. This novel perspective helps explain how changes in climate, such as altered rain patterns, could reshape biodiversity.

Elegant field experiments with annual plants support Levine’s hypothesis that competition for water manifests not just as a fight over resources but as a constraint on the time available for growth. He further expands this model to show how, under climate change scenarios where storms become larger but less frequent, perennial plants may also experience changes in competitive dynamics, potentially benefiting biodiversity in the long run.

Levine’s work adeptly combines theoretical and experimental ecology, offering insightful predictions relevant to biodiversity conservation in changing climates.

 

E. Lucy Braun Award for Excellence in Ecology
Alivia Nytko, Ph.D. student, Department of Ecology and Evolutionary Biology, University of Tennessee, Knoxville         

Lucy Braun, an eminent plant ecologist and one of the charter members of the Society, studied and mapped North American forests and described them in her classic book, The Deciduous Forests of Eastern North America.

To honor her, the E. Lucy Braun Award for Excellence in Ecology is given to a student for the outstanding poster presentation at the ESA Annual Meeting. Papers and posters are judged on the significance of ideas, creativity, quality of methodology, validity of conclusions drawn from results and clarity of presentation.

Alivia Nytko is the recipient of the 2024 E. Lucy Braun Award for her poster presentation at the 2023 ESA Annual Meeting titled, “Plant rarity related to phylogenetic divergence in biomass: Implications for ecosystem function.”

Nytko’s research challenges conventional views on plant rarity by suggesting that rarity might often be an evolutionary adaptation rather than a result of environmental constraints. Using data from 25 Eucalyptus species, her research examines how natural selection influences plant traits that in turn shape plants’ range sizes and habitat needs. Her findings reveal that rare species are consistently smaller than their more common counterparts and that this trait has evolved multiple times across different groups.

By linking rarity to plant size and showing how rarity can evolve, Nytko’s work highlights potential pathways for promoting conservation of rare plant populations. In particular, protecting rare species may require a re-assessment of why species are rare in the first place, and what can be done to maintain them into the future.
