Eighteen SBF recipients from Earth & Atmospheric Sciences, Ecology & Evolutionary Biology, Entomology, Lab of Ornithology, Natural Resources & the Environment, Neurobiology & Behavior, and Soil & Crop Sciences
Udita Bansal (Ecology & Evolutionary Biology)
Cryptic or Colorful: Does Body Coloration at Sleep Sites Confer Protection to Animals at Night?
Advisor: Swanne Gordon
Bansal studies how sleep ecology impacts body color evolution in animals. To date, no study has investigated whether animals use color to protect themselves while sleeping at night. For example, by having darker body colors, animals may be less visible under lunar light conditions. Further, since visibility can also be affected by contrast against their background, animals may choose where they sleep to minimize detection. In this study, Bansal aims to gather empirical evidence about how body color may affect predation risk for animals sleeping at night. She will use predation experiments with clay models of chameleons in their natural habitat. As anthropogenic effects constantly modify natural habitats and increase light pollution, prey may become more vulnerable to predation at night. It is therefore vital to understand how different traits can enable organisms to withstand increasing threats, including those at night.
Ethan Bass (Ecology & Evolutionary Biology)
Root Secondary Metabolites as Mediators of Plant-Soil Feedbacks
Advisor: Andre Kessler
Bass is a plant chemical ecologist and Ph.D. candidate working in André Kessler’s lab in the Department of Ecology and Evolutionary Biology. His research focuses on the evolution of root defenses and their cascading effects on plant interactions and community assembly. Support from this SBF award will be used to investigate how plant defensive metabolism contributes to functionally shaping rhizosphere microbial communities in tall goldenrod (Solidago altissima). While interactions with soil microbes are recognized as an important driver of plant community assembly, it is still poorly understood how variation in these microbial community feedbacks is shaped by selection. The proposed project aims to elucidate the mechanisms underlying intraspecific variation in these feedbacks, enhancing our understanding of broad patterns of plant diversity. Additionally, this knowledge could be applied to the development of new strategies to sustainably increase agricultural yields.
Yuqing Chen (Natural Resources & the Environment)
Can Aquaculture Farm Animals Provide an Ecosystem Service by Hybridizing With Native Stocks?
Advisor: Matthew P. Hare
Chen is broadly interested in population genetics, evolutionary genomics, and marine conservation. She is studying the dynamics and consequences of genetic introgression from aquaculture animals to native populations, which depend on the interplay between evolutionary processes and demographic factors. With the support of SBF funding, she will use genomics to measure the extent and geographic pattern of farm to native admixture of Eastern oysters in coastal Connecticut. The study aims to infer factors that affect admixture patterns and assess the fitness impacts of introgression. The findings will inform management agencies about the risks/benefits associated with admixture to support sustainable marine aquaculture.
Cameron Coles (Ecology & Evolutionary Biology)
Understanding the Factors Leading to Spongy Moth Defoliation Through the Lens of Remote Sensing
Advisor: Xiangtao Xu
Climate change is likely to amplify insect damages to forest ecosystems. Understanding the key environmental factors governing population dynamics, especially outbreaks, will be critical for predicting how forests will be impacted and properly planning forest management. The consequences of outbreaks can be seen in all parts of the ecosystem ranging from shifting tree species composition; food sources and habitat for organisms within the forest; disturbance regimes; carbon cycling; soil nutrient dynamics; and more. Coles studies the invasive European spongy moth (Lymantria dispar dispar), whose outbreaks can leave forests devoid of leaves. He uses state-of-the-art, high-resolution remote sensing data, supplemented by in situ measurements, to understand the spatiotemporal patterns of defoliation in relation to key environmental factors. Using this information, he plans to incorporate defoliation into computational models to predict long-term impacts to forest structure, function, and productivity.
Hannah Gurholt (Ecology & Evolutionary Biology)
Sex in the (Artificially Lit) City
Advisor: Swanne Gordon
Artificial light at night (ALAN) is a threat to biodiversity because it provides many organisms with false cues of the sun, altering how communities move, behave, and survive. Light pollution either comes directly from streetlights and buildings or indirectly from reflections off the atmosphere. One of the world’s most well-known butterflies, the monarch (Danaus plexippus), has altered its migratory patterns due to false cues from ALAN. Monarchs begin copulation at sunset and mate until sunrise, making their mating behavior vulnerable to ALAN. However, the effect ALAN has on reproduction and fitness of monarchs is unknown. Gurholt will investigate how ALAN shapes monarch development, reproduction, and fitness. Accordingly, she will expose lab-reared monarchs to ALAN conditions and record mating duration, spermatophore transfer, and larval survival. She will use the monarch’s endangered status as a platform to advocate for the reevaluation of multidimensional consequences of artificial light at night.
Juan Pablo Jordán (Ecology & Evolutionary Biology)
Maize Intercropping Systems: Impact of Seed Chemical Treatment on Plant-Rhizosphere Interactions and Their Effects on Resistance to Herbivores and Pathogens
Advisor: Andre Kessler
Jordán’s research is focused on understanding how plant-plant interactions through intercropping mediate resistance to herbivores and pathogens. With SBF funding he will investigate how seed chemical pesticides affect the rhizosphere soil microbiome, interactions with beneficial arbuscular mycorrhizae fungi, and their effect on the production of chemical defenses. The goal is to evaluate the impact of seed pesticides on the interaction network of intercropped maize plants.
Hannah Kirkland (Natural Resources & the Environment)
Assessing the Impacts of Deer and Other Stressors on Native Woodlands in Scotland Using the Sentinel Approach
Advisor: Bernd Blossey
Scotland is facing an ecological crisis that sees record high deer populations limiting woodland regeneration, threatening plants and animals and exacerbating climate change. Despite recognition of the damaging ecological impacts of deer, there remain crucial unanswered questions preventing sustainable deer management and the recovery of woodlands across Scotland. Kirkland will apply the sentinel approach, which uses planted saplings as indicators, to study the effect of deer and other stressors on woodlands and identify potential restoration measures that could ameliorate them. She will test whether the sentinel approach, recently developed at Cornell University, is a reliable tool for assessing deer impacts and gauging management outcomes in Scotland. Her research aims to improve outcomes for biodiversity in Scotland by collecting crucial evidence to guide the decisions of practitioners working on deer and woodland management and ministers and public officials responsible for environmental and climate policy.
Kimberly Navarro-Velez (Lab of Ornithology)
Disentangling the Interactions Between Resident and Migratory Birds on Wintering Grounds
Advisor: André Dhondt
Navarro-Velez’s research focuses on the interactions between migratory and resident birds on wintering grounds. In particular, she is interested in testing the hypothesis of migratory species having an impact on the residents. Surprisingly, this has only been explored in a handful of studies. She will incorporate different approaches including habitat occupancy modeling, fecal sampling for metabarcoding, behavioral observations, and morphometrics. By improving our knowledge of the natural history of these species, how and when they interact, and what are the limiting resources, we can guide conservation strategies to mitigate the impact that human activities have on them. Without thorough conservation plans that consider every aspect of the natural history of the species, we cannot assure biodiversity conservation in the long term. This is imperative in the context of climate change, which likely will increase intra and interspecific competition, and thus the likelihood of extinction for many species.
Jaime Ortiz (Natural Resources & the Environment)
Conservation Genomics of the Endangered Brown Sea Cucumber in the Galapagos Archipelago
Advisor: Nina Therkildsen
Ortiz is interested in conservation genomics. Currently, he is developing tools to improve meta-barcoding accuracy for species identification on eDNA and aquaculture feeds.

Investigating the Effects of Harvesting on Body Size of the Eastern Oyster, Crassostrea Virginica, Within the Guana River Marsh Aquatic Preserve: a Paleoecological Approach
Advisor: Greg Dietl
Pier is a Ph.D. student in Dr. Gregory Dietl’s lab in the Department of Earth and Atmospheric Sciences. She studies conservation paleobiology, a field that applies paleontological theory and methods toward modern conservation issues. Her research is applying new methods of coring oyster reefs from Guana River within the Guana Tolomato Matanzas National Estuarine Research Reserve (GTM) in northeast Florida. Current oyster monitoring only began in 2014, although the aquatic preserve was established in 1985, when oyster harvest was also prohibited. With funding from SBF, she will date oyster shells within the oyster reef cores to determine reef age and how oyster size has changed over time. This will address information gaps regarding oysters in GTM and help inform management decisions.
Shashank Poudel (Natural Resources & the Environment)
Estimating Leopard Density in Human-Dominated Landscapes in Nepal
Advisors: Angela Fuller & Richard Stedman
In Nepal, increasing attacks on livestock and humans by leopards threatens local livelihoods and results in retaliatory killings of leopards. Leopards account for more than 85% of the total wildlife attacks on humans in the study system. Thus, human-leopard conflict can contribute to leopard population declines and the unwillingness of locals to coexist with leopards. This proposal will supplement the parent research aimed at exploring key drivers and impacts of human-leopard interactions in the Chitwan Annapurna Landscape Nepal to generate adaptive policy interventions for sustainable biodiversity conservation. This proposal will aid in the collection and analysis of data related to leopard abundance and density. The data collected from the Sustainable Biodiversity Fund grant will be synthesized with the existing data on leopard distribution, diet, and social data on conflict collected in 2021/22 to produce a national-level policy document to foster sustainable human-leopard coexistence.
Sylvana Ross (Entomology)
It’s Getting Hot in Here: Thermal Tolerance Across the Urban Gradient of the Ant Species Tapinoma Sessile
Advisor: Corrie Moreau
Global urbanization is creating novel environments that limit genetic diversity and isolate populations that either adapt to or diminish from their new changed environment. To observe the pace of evolution in urban ecosystems, Ross will study how phenotypic plasticity and genetic adaptations allow populations to transition to urban environments. She will study the native North American ant species Tapinoma sessile, where urban colonies are more expansive than rural colonies. In the city, their ability to tolerate the higher temperatures through possible morphological and genetic adaptations may contribute to their urban success. Ross will compare urban and rural populations in cities across the U.S. to see if there are body size or color differences and then look at their DNA to compare molecular differences when they are exposed to urban temperatures. Studying the impact of warming urban temperatures can give insight into how the global climate crisis impacts vulnerable populations and ecosystems.
Peter Searle (Ecology & Evolutionary Biology)
The Evolution and Maintenance of Biodiversity in Rockfish (Sebastes): Depth Segregation and Coloration
Advisor: Swanne Gordon
Searle is interested in what ecological and evolutionary processes allowed rockfish (Sebastes) to diversify into more than 110 marine species. Using whole genome sequences, as well as a phylogenetic comparative approach, he will test if depth segregation and coloration are important mechanisms associated with the evolution of these fishes. Rockfish are an important food source that have been intensely fished both commercially and recreationally. Overfishing has resulted in significant range contractions, biomass declines, and population collapses. Understanding what drove the evolution of rockfish species in the past will inform how rockfish species will respond to future anthropogenic impacts.
Raunak Sen (Neurobiology & Behavior)
Understanding the Origins and Maintenance of Cryptic Biodiversity
Advisor: Kerry L. Shaw
Sen is broadly interested in how biodiversity is generated. Specifically, he is working on a clade of Hawaiian crickets of the genus Laupala to understand how new species form. This genus has the fastest speciation rate in invertebrates and is morphologically cryptic but differ in their sexual signals, making it a great model system for speciation studies. He is trying to understand the origins and maintenance of reproductive isolating barriers between species in this genus. Using a combination of behavioral ecology experiments, population genomic analysis of sequence data and ecological methods, he wants to understand the extent to which they are reproductively isolated, the genomic basis of these barriers and the role of ecological differentiation in this radiation.

Population Genetics and Local Adaptation in Alaskan Red King Crab to Inform Stock Enhancement
Advisor: Peter B. McIntyre
Fisheries are the largest mass harvested, wild food source on Earth. They help feed billions of people and support tens of millions of livelihoods. Marine species in general face threats to their persistence from a multitude of recent ecological changes, and for commercially harvested arctic species, those threats are compounded by fishery mortality and oceanic warming. Red king crab (Paralithodes camtschaticus) is a culturally and economically important invertebrate fishery in Alaska that has declined in abundance leading to localized fishery closures. Alaskan fishery managers are considering stocking red king crabs across Alaska but are concerned about the genetic risks of stocking into wild populations. Population genetic investigations in St. John’s proposed work will assess these risks and provide crucial information on how to sustainably stock red king crabs in Alaska, hopefully leading to a recovery of the fishery and preservation of the ecosystem and communities that depend on it.
Charles Arthur Tebbutt (Natural Resources & the Environment)
Assessing the Social-Ecological Value of Artisanal Rubber Agroforestry for Biodiversity and Peacebuilding in the Colombian Amazon
Advisor: Shorna Allred
Tebbutt’s research examines the social-ecological impacts of agroforestry systems in the post-conflict Colombian Amazon. This key ecological corridor between the Andes and the lowland forest faces land use pressures related to the transition from illicit crops, as well as the impacts of multidimensional poverty and violence. Agroforestry centered around native plant species such as the rubber tree (Hevea brasiliensis) and cacao (Theobroma cacao) offers a potential alternative to environmentally harmful cattle ranching practices that may benefit biodiversity as well as local livelihoods. By combining bioacoustics methods to study birdsong with survey data on peacebuilding indicators, Tebbutt works with the Cornell Lab of Ornithology and local partners to understand the effects of different land uses on people and nature in the world’s second most biologically diverse country.
Marisol Patricia Valverde Montellano (Ecology & Evolutionary Biology)
What Can Soundscapes Tell Us About Tropical Freshwater Community Dynamics?
Advisor: Alexander Flecker
The study of freshwater soundscapes, which comprise the biological (biophony), geophysical (geophony) and anthropogenic (anthrophony) sounds from a given area, is an emerging research area in aquatic ecology and provides a novel way of addressing ecological and biodiversity questions in freshwater habitats. These habitats are home to a variety of underwater sound-producing organisms, including fishes, which are the vertebrate group with the highest diversity of sound-producing mechanisms. In this project, based in the Brazilian Amazon, Montellano propose to use passive acoustic monitoring to investigate how the soundscape is structured and partitioned by species-rich tropical fish communities. This work will increase the understanding of fish population and community dynamics in the Amazon and set the stage for the development of a new tool for the monitoring and conservation of Amazonian freshwaters.
Sophie Westbrook (Soil & Crop Sciences)
Restoring Biodiversity and Ecosystem Services to Agricultural Landscapes: Are Annual Flower Strips the Answer?
Advisor: Antonio DiTommaso
Flower strips increase agroecosystem biodiversity at multiple trophic levels. This practice does not require major agroecosystem redesign or yield losses, so theoretically it is available to many growers. However, despite established literature on flower strips and subsidies available in the United States and Europe, this practice is not widely adopted. Westbrook’s research seeks to identify flower strip systems that are both effective and more accessible than standard systems. The work will focus on preserving growers’ management flexibility by requiring only a single year’s commitment and avoiding in-season field operations. It also will explore how delayed planting and landscape context modify the effects of flower strips. These findings will enable Northeastern growers to make accurate, site-specific predictions about the costs and benefits of flower strips.

She is interested in the microbial ecology and evolution of Acinteobacter spp. in floral and pollinator environments. She is currently studying the functional capabilities of Acinetobacter spp. and their role in solitary bee pollen provisions. Support from the SBF will fund next-generation sequencing efforts to determine the diversity and functional capacity of bacteria present in local solitary bee pollen provisions. Understanding the bacterial structure and genomic composition in pollen provisions will help elucidate the presence and role of Acinetobacter spp. in solitary bee-associated environments. Genomic insight from the microbial community present in larval food sources could also suggest possible ecological roles floral microbes have on foraging pollinators, namely solitary bees.

Maria Gannett (Horticulture)
Maria Gannett is a Ph.D. student in Horticulture, working with Dr. Jenny Kao-Kniffin and Dr. Toni DiTommaso. She is interested in how manipulating the soil chemical environment can alter plant competition and how the soil microbial community mediates this effect. With support from SBF she will explore the idea of improving competition of crops that form microbial symbiotic relationships by adding high carbon amendments to soil, which would immobilize nitrogen by stimulating soil microbial growth. Since many agricultural weeds are less competitive in soils with lower nitrogen availability, this idea has the potential to be used as a weed management tool. By beginning to tease apart the mechanisms of plant competition in low and high nitrogen environments she hopes to understand the situations where this technique is successful. Ultimately her goal is to expand and refine sustainable weed management techniques using ecological knowledge.

This project will contribute to a growing body of work examining soil microbiome manipulation as a tool for sustainably improving crop performance.
Aaron Iverson (Entomology)
Aaron Iverson is an agroecologist and postdoctoral associate in Scott McArt’s lab in the Department of Entomology. He is broadly interested in how agricultural systems and surrounding landscapes can conserve biodiversity, and how that biodiversity can have on-farm benefits, particularly through biological control and pollination. His SBF research, in collaboration with Heather Grab, will focus on determining the role of multiple stressors, including pesticides, pathogens, and habitat/resource loss, on bee communities on New York State farms. Although each of these stressors is known to negatively impact bees, determining their relative importance has been hampered by the difficulties of being able to rigorously assess multiple stressors simultaneously. This project will address this gap, providing new evidence for management practices or policy decisions that support pollinators and the farmers and consumers that depend on them.

Her research intends to better inform forest management practices to deal with climate change.
Celina Scott-Buechler (Atmospheric Science)
Growing up in India, Mexico, Germany, and the US, Celina observed from a young age the effects of human-driven change to ecosystems and the climate. As she matured intellectually, Celina began to realize the inequity of these impacts and, thus, turn her attention to the environmental justice implications of climate action: addressing environmental challenges, namely climate change, in ways that precipitate socially equitable societies. Until recently, Celina was pursuing the study and conservation of coral reefs. Her professional/academic direction changed, however, when she served on the Cornell delegation at Conference of Parties (COP23), the UN’s annual environmental summit. Immersed in the COP, she realized the great need for macro-scale, cooperative climate action that not only reduced but in fact removed carbon from the atmosphere. Since, her research has focused on the ocean’s role in negative emissions, attempting to identify climate solutions that are ecologically and socially viable. Celina is continuing this research as an MS/PhD candidate, investigating several methods of carbon dioxide removal (ocean and terrestrial), their tradeoffs, and how they can provide economic opportunity. She is especially interested in how these approaches and technologies can co-produce sustainable sources of nutrition and minimize land and water use. One such solution is Algal Bioenergy Carbon Capture and Storage (ABECCS), which relies on the mass-production of algae for biofuel production. ABECCS shows promise to meet fuel needs of heavy shipping and aviation, for which no viable sustainable alternative exists, while producing high-protein feed—all without competing for arable land or fresh water.
Steven Wilcox (Applied Economics and Management)
Steven Wilcox is a Ph.D. candidate in Applied Economics and Management. His primary interests are in agriculture and natural resources in developing and developed countries, and particularly in the relationship between land-use decisions, welfare, and conservation.

Kaitlin Deutsch (Entomology)
Kaitlin is a Ph.D. student in the Department of Entomology, working with Scott McArt. Her research is focused on pollinator disease ecology, particularly the role of non-bee insects in disease networks. With SBF funding, she will investigate the threat posed by honey bee viruses to hoverflies. While these diseases have been tied decisively to bee declines, little is known about their prevalence in, and effect on, non-bee insect pollinators. Determining whether these bee pathogens are able to infect non-bee floral visitors such as hoverflies is a vital first step in understanding the effects of pathogens on the broader pollinator community.
Katherine Eisen (Ecology and Evolutionary Biology)
Kate Eisen is a Ph.D. candidate in Monica Geber’s lab in the Department of Ecology and Evolutionary Biology. Her research explores how plants interact ecologically and evolutionarily where they share pollinators.

Results of her work will provide new insights into global plant virome diversity and the development of viral resistance as a quantitative trait.
Cinnamon Mittan (Ecology and Evolutionary Biology)
Cinnamon Mittan is a Ph.D. candidate in Kelly Zamudio’s lab in the Department of Ecology and Evolutionary Biology. She is interested in the dynamics of adaptation and evolution in invasive species, and uses Rhinella marina (the cane toad) as a model system. With a combination of fieldwork, experiments, and genomics, she studies how invasive toads in Florida have adapted to the “frigid” central Florida climate, the coldest place cane toads are found anywhere in their range. With funding from SBF, she will examine differences in gene expression between cold-tolerant and cold-intolerant toads during cold stress to further elucidate the genetic processes involved in this adaptation.
Nine SBF recipients from Ecology and Evolutionary Biology, Horticulture, Natural Resources, and Plant Biology
Lina Arcila (Ecology and Evolutionary Biology)
Lina Arcila Hernández is a PhD candidate in Anurag Agrawal’s lab in the department of Ecology and Evolutionary Biology. Overall, her research focuses on understanding how plants and insect herbivores interact and the effect of those interactions in species diversity. She is currently working with experimental and genetic approaches to determine which eco-evolutionary processes maintain the differentiation of feeding and oviposition behaviors among populations of insect herbivores. The SBF funding will allow her to test the relative importance of behavioral phenotypes, geographic isolation, and environmental clines to the population genetic structure in milkweed stem weevils (Rhyssomatus spp.). Determining the relative importance of these factors for the maintenance of population differentiation is an important step for understanding the origin of biodiversity.
Pepe Casis (Natural Resources)
Pepe Casis is a PhD student in the Department of Natural Resources and the Environment, studying environmental policy under Steven Wolf. Pepe has been an environmental economist for more than thirteen years; however, his somewhat recent disenchantment with neoclassical economics has allowed him to expand his horizons on how to design and implement environmental projects. Thus, his research is now based on environmental governance, deliberative valuation methods, and collaborative policy design; combined with neoclassical environmental economic instruments (old habits die hard). He hopes that this combination will allow him to contribute to a more realistic and humane design of economic instruments for conservation. His research focuses on the design of an environmental governance instrument based on collaboration for the Sierra Norte in the state of Oaxaca, Mexico.
David Chang van Oordt (Ecology and Evolutionary Biology)
David Chang van Oordt is a PhD student in David Winkler’s lab in the department of Ecology and Evolutionary Biology. His research focuses on the overlap of bird migration and disease ecology. He works on the effects of long distance movement on patterns of parasite diversity and evolution, and how do birds provide the means for parasite dispersal and population connectivity. He will use the SBF award to study the link between breeding and wintering site vector diversity on transmission of avian malaria in tree swallows. This will help understand the risk of infection across a bird’s migratory route based on parasite diversity, vector abundance, and migratory timing. This is especially important in the face of climate change where we expect insect phenologies and distribution ranges to shift, and it can help predict future spread and dispersal of different strains of avian malaria.
Olivia Graham (Ecology and Evolutionary Biology)
Olivia Graham is a PhD student in Dr. Drew Harvell’s lab in the Department of Ecology and Evolutionary Biology. A marine ecologist, she especially enjoys infectious disease research that has direct conservation and management applications.

Katie Sirianni (Shoals Marine Lab)
Katie Sirianni is a Ph.D. candidate studying community and metacommunity dynamics. In nature, communities rarely exist in isolation and are instead connected to other communities by dispersal, forming a network known as a metacommunity. Metacommunities are also formed when humans fragment habitats such as forests. Though ubiquitous, metacommunity dynamics are often difficult to study because they can occur at a large spatial scale. To avoid this problem, Katie carries out her research in a remarkable natural plankton metacommunity made up of over 4000 small rock pools at Shoals Marine Lab on Appledore Island, ME. Funding from the SBF will help her to determine whether the zooplankton in these pools compete, if they are able to coexist within each pool, and how their presence in a pool is mediated by dispersal. This research has implications for other less tractable metacommunities.
