The Hutchinson Environmental Program, named in honor of G. Evelyn Hutchinson, the father of modern ecology, supports the environmental priorities identified in Yale’s strategy to advance the sciences. The program aims to enable creative collaborative research in the environmental sciences at Yale by facilitating the development of diverse academic excellence at the postdoctoral level. This format develops the framework established by the first Hutchinson call (from Fall 2019) by segueing the program into an annual and continuing program. These are two-year postdoctoral fellowships (contingent on success in year one) with a starting salary of $68,000, plus up to $10,000 for research and travel. Funds will also be available to support cohort projects, symposia, workshops, and training in science communication.

Cluster V - Linking The Built Environment, Greenspace, Energy, Climate, and Health

In the context of unprecedented global urbanization, with urban populations projected to reach 68% by 2050, both urban infrastructure and vegetation are integrally related to the most pressing environmental crisis of our time—climate change. Current urban infrastructure is energy- and pollutant-intensive, representing an important opportunity for innovative green building solutions, while urban vegetation presents a critical opportunity to mitigate the urban heat island effect, improve air quality, and provide social, cognitive, and physical benefits to inhabitants. To date, green buildings and outdoor greenspace have been primarily researched separately. Our YIBS Hutchinson Cluster employs an interdisciplinary, collaborative effort to synergistically investigate how indoor and outdoor greenspace impact human health and well-being in the context of environmental quality, energy use, and climate.

Cluster VI - Predicting Ectotherm Responses to Climate Warming: Integrating Behavior, Physiology, Genomics, and Life History in Amphibians and Reptiles

Climate warming can increase body temperature of ectothermic animals, accelerate metabolism, affect reproduction, and induce mortality by overheating. Ectotherms may buffer rising environmental temperatures through thermoregulatory behavior or phenotypic adaptation. Yet, our ongoing work with lizards and frogs suggests that behavioral and physiological adjustments are unlikely to operate in tandem. Ectotherms with active thermoregulation limit thermal selection on their upper thermal limits. By contrast, ectotherms with thermal passivity have shifted their physiology over time, a product of strong thermal selection. These initial discoveries indicate that thermoregulation constrains physiological adjustment. This Hutchinson project aims to build an integrative framework to expand our predictive capacity under climate change. We are interested in (1) linking thermal behavior and physiological evolution of amphibians and reptiles using a macroevolutionary approach, (2) performing temporal comparisons of behavior, physiology, and life history in wild populations, and (3) identifying the genetic signatures of thermal adaptation.

Cluster III - The Genomic Basis of Climate Resiliency

Current climate models predict more extreme and variable temperature and precipitation regimes, and hotter, more extreme droughts are a leading cause of widespread forest mortality. Despite their central role in plant ecological adaptation, potential variation in complex physiological processes such as drought tolerance are rarely surveyed at a population level. Furthermore, we know very little about either the genetic basis or potential plasticity of plant drought tolerance. This is problematic, because if and how species will adapt to climate change depends in large part on the amount and distribution of genetic variation for ecologically relevant traits. This project seeks to bridge global ecology and evolutionary genetics by exploring the genetic architeture and within species variation of plant drought tolerance.

Craig Brodersen Professor of Physiological Plant Ecology, Yale School of the Environment Website My lab group is focused on structure-function relationships in the transport systems in plants; specifically, the vascular systems and their linkage to the evaporative and absorptive surfaces in leaves. We use a combination of methods, including high-resolution X-ray microCT imaging, to study these systems in three-dimensions and in-planta as a means of characterizing physiological thresholds during stressful events like drought. Another long-term goal of our research program is to understand how the natural diversity in photosynthetic and hydraulic systems of plants might be used for the design of novel materials and designs to mitigate rising atmospheric CO2.

Jennifer Coughlan Assistant Professor of Ecology & Evolutionary Biology Website The Coughlan lab seeks to understand the process of speciation and adaptation by integrating field work, common garden experiments, development, and quantitative and population genomics. We focus on a wild flower genus, Mimulus. Erika Edwards Professor of Ecology & Evolutionary Biology Curator-in-charge of Botany and Paleobotany, Yale Peabody Museum Director, Marsh Botanical Gardens Website My lab group studies the evolutionary origins of complex trait syndromes in plants. We are especially drawn to traits that result from convergent evolution: phenotypes that have arisen many times, in distantly related lineages and within different evolutionary contexts. Our approach is centered on the concept of developing “model lineages” for macroevolution. Our work is highly integrative, and we are typically engaging in some combination of phylogenetics, physiology, anatomy, genomics, and field ecology to answer our questions. We tend to focus on traits that have played especially prominent roles in the adaptation of plant lineages to novel environments. For example, we have worked for some time on the evolution of different photosynthetic systems in plants, and how their evolution is connected to the global carbon cycle. We are also interested in evolutionary transitions between tropical and temperate forests, and between desert and alpine environments.

Cluster IV - Mechanisms and Trajectories of Post-Disturbance Recovery in Tropical Forests

Tropical forests hold over half of the world’s biodiversity and play a critical role in regulating Earth’s climate, but also face some of the highest rates of land-use change. More than half of the world’s tropical forests are currently in a state of recovery following human disturbance. This includes secondary forests undergoing sucessions after deforestation for agriculture, as well as mature forests recovering from degradation from logging or recent shifts in fire regimes. While understanding the trajectories of recovery is critical for conservation and climate mitigation, two outstanding questions remain largely unanswered. First, how below and aboveground feedback influence forest recovery pathways and their biodiversity trajectories. Second, how environmental and biological filters shape forest vulnerability to compounding disturbance events associated with droughts, blowdowns, wildfires, and edge effects. Addressing these questions will advance our understanding of underlying biotic mechanisms driving successional dynamics and the potential consequences for forest functioning and biodiversity.

Cluster I - Deep Learning and Image Processing for Transformational Environmental Science

This cluster focuses on the application of Image Processing and Machine Learning to a range of problems in Environmental/Ecological Sciences. High-resolution imaging sensing has enabled the production of huge amounts of data that is informationally-dense and relatively easy to share. A number of promising opportunities exist to leverage these. Using traditional image processing techniques such as object detection and segmentation, for example, a wide range of modelling activities can be performed in order to quantify various aspects of plants and animals such as for phenotyping or other classification activities. Furthermore, with the increased proliferation of high quality and inexpensive sensors comes a proportional increase in the amount of data from them that must be analyzed. There are a number of directions at the intersection of machine learning and signal processing that are very promising, allowing functions such as automatically “filtering” datasets (such as to remove uninteresting clips), processing for automatic ID of animals, and many more.

Project I - Deep Learning for Automated Plant Phenotyping

Climate-related phenotypic changes in plants are perhaps most prevalent in leaves, where evapotranspiration, temperature regulation, and photosynthetic intensity are adjusted with changes in leaf appearance, such as size, shape, length to width ratio, and apex, base, lobing, and tooth form. This project would leverage Herbarium digitization efforts, which, over the past two decades have resulted in the availability of millions of images of herbarium specimens. Using these collections, we will apply modern computer vision and data-driven machine learning approaches to automatically extract leaf contours and quantify their phenotypic properties. By assembling large datasets of extracted phenotypes with their corresponding climate data, we will perform large-scale analysis of correlations between leaf phenotypes and climate conditions at massive and unprecedented taxonomic and geographic scales.

Cluster II - Trophic Ecology of African Savannas 

African savanna ecosystems are at the brink of an ecological transformation. Woody plants are encroaching due to changes in fire management, forcing by climate and [CO₂], and misguided afforestation schemes. Fire – an integral part of grassy systems, often conceptualized as another ‘consumer’ of productivity – is decreasing in extent. Wild megafauna faces increasing pressures from fragmentation, hunting, and infectious disease, threatening the last extant community of large herbivores on Earth. Meanwhile, proponents of natural climate solutions increasingly identify these diverse and ancient savanna ecosystems as ‘degraded’ and have targeted them for afforestation and transformation (billed as ‘restoration’), accelerating threats from global change and agricultural transformation. These proposals have gained traction, just as they have marginalized local communities and scientists. This cluster aims to create a community of African ecologists at Yale, bringing together three research groups interested in trophic interactions in African savanna ecosystems and recruiting postdocs to create a cluster for the study of African savanna ecology.

	Pincelli Hull Associate Professor of Earth and Planetary Sciences Associate Curator of Invertebrate Paleontology, Yale Peabody Museum Website My research focuses on understanding the causes and consequences of major environmental change in earth’s history and how these events relate to evolution of life and ecosystems. My work centers on reconstructing the history of the open oceans because of the relatively resolved environmental and biotic records provided by microfossils over the last ~150 million years. From these records, we reconstruct past climatic and oceanographic dynamics, the causes and consequences of mass extinctions, and the response of life to environmental change large and small.
	Martha Muñoz Assistant Professor of Ecology & Evolutionary Biology Assistant Curator of Vertebrate Zoology (Herpetology), Yale Peabody Museum Website The Muñoz lab studies how organisms behaviorally interact with their environments and how those interactions impact micro- and macroevolutionary patterns of diversity. We use our discoveries to make informed predictions of species’ vulnerability to ongoing global change. Some ongoing research themes in the lab are: (1) mechanisms of niche evolution; (2) ecological and evolutionary physiology; (3) spatial patterns of biodiversity; (4) form-function evolution; and (5) behavioral evolution. The Muñoz lab works primarily with terrestrial ectotherms (especially reptiles and amphibians), but is open to other study systems.
	David Skelly Frank R. Oastler Professor of Ecology, Yale School of the Environment Professor of Ecology & Evolutionary Biology Director, Yale Peabody Museum  Website Our lab studies the ecological and evolutionary influences of environmental change on animal populations.  We are particularly interested in the means by which species cope with human caused changes such as landscape conversion, the introduction of synthetic chemicals or changing climate.  To what extent are persisting species adapting to altered environments and how quickly and at what spatial scales can such adaptation occur?  We use long term observations as well as field and laboratory experiments to link pattern to mechanism and we seek understanding that can help us make better decisions about the environment.  A lot of the work is on frogs because they live in such a variety of contexts and because they are cool.
	David Vasseur Professor of Ecology & Evolutionary Biology Website Research in my lab incorporates theory and laboratory experiments to study the ecological and evolutionary responses to environmental variation and to the variation that exists amongst individuals.  Within this broader focus, two themes currently dominate my lab’s activities.  The first is aimed at understanding the consequences of thermal variation in space and time on the fitness of individuals and populations.  In addition to models of evolutionary rescue and behavioral microclimate use, we are carrying out experiments to better characterize the ecological effects of thermal acclimation in order to improve ecological forecasts.  The second theme aims to characterize how the incorporation of intraspecific variation impacts ecological paradigms such as coexistence and the stability of ecosystems.

Theme II - Climate and Greenhouse Gases

Atmospheric levels of CO₂, CH₄ and N₂O are increasing, leading to planetary warming. We are seeking candidates whose research can contribute to our general understanding of the generation and management of greenhouse gases (GHG). Because of growing interest in global methane among a group of Yale faculty, we are particularly interested in building a cohort of postdoctoral fellows who can advance knowledge of the production and control of CH₄ losses from natural and human-managed systems. Successful applicants will work in a highly collaborative environment around themes including, but not limited to: (1) GHG fluxes from ecosystems and the energy sector; (2) microbial ecology and evolution relevant to GHGs; (3) GHG pathways in plants; (4) GHG dynamics in deep time; and (5) natural climate solutions.
