Graduate Student Climate Adaptation Partners (GradCAP)

A graduate student from the University of Maine overlooks her research field in the setting sun

A project designed to build a virtual consortium of Masters and Doctoral students working on climate adaptation in agriculture and forestry. Nominated by a university partner within the USDA Northeast Climate Hub network, GradCAP scholars work with Climate Hub leadership, university representatives, and coordinating staff at the University of Maine to develop a digital library of information and a webinar series based on their research. This unique program offers participating students networking opportunities with project leadership across institutions and provides a means to spark new ideas in a collaborative setting. The current cohort of 15 GradCAP scholars represent six USDA Northeast Climate Hub partner institutions, that range geographically from West Virginia to Maine.

Expanding Aquaculture Opportunities through Ecologically-sound Diversification

Michael Acquafredda is a third year PhD candidate and is advised by Dr. Daphne Munroe. He is an advocate for sustainable aquaculture practices that are beneficial to farmers and aquatic ecosystems, alike. Specifically, Mike is studying husbandry techniques for the Atlantic surfclam (Spisula solidissima), which has the potential to become an alternate crop species grown on shellfish farms throughout the Northeast. Since the coastal waters of this region are warming due to global climate change, Mike is also investigating the heritability of heat-tolerance in surfclams. Additionally, Mike is studying interspecific competition among four ecologically and economically important bivalves in order to assess the viability of bivalve polyculture.

Conservation Policy for Grassland Birds in Agricultural Landscapes

Michael's research attempts to better understand the interconnections between climate, economics, hayfield management, and grassland bird population ecology. The goal is to identify effective conservation measures that are economically viable and minimally impact farmers and food production. Michael is generally interested in the conservation implications of how complex systems such as agriculture and natural ecosystems interact and respond to global change.

Temporal Dynamics of Songbirds along an Elevational Gradient in the Appalachian Mountains

Gordon is a graduate research assistant at West Virginia University studying birds in the Appalachian Mountains of West Virginia. In particular, he is using a long term dataset to assess songbird temporal dynamics on an elevational gradient to see if certain species may be moving up or down in elevation. Additionally, Gordon is evaluating which environmental factors predict Canada Warbler occupancy in the southern extent of their breeding distribution. When Gordon is not researching birds, he will often be found birding for fun, hiking, or fly fishing.

Mitigating Gaseous Carbon and Nitrogen Losses from Northeastern Agricultural Soils via Alternative Soil Management Practices

Kyle is a second year Masters student at the University of Vermont (UVM) researching the potential for best management practices (i.e., conservation tillage, alternative manure application methods/timing, and cover cropping) to mitigate nutrient losses via greenhouse gasses from agricultural soils without compromising soil fertility or crop yield. Additionally, Kyle will be studying the molecular mechanisms responsible for nitrous oxide emissions from agricultural soils and how these fluxes are impacted by management practices. His overall research goal is to provide farmers with sustainable soil management practices that will retain nutrients within soils, thereby providing farmers with ideal crop yields/revenue while also improving environmental quality.

Utilizing Native Endophytic Bacteria to Reduce Abiotic Stress in Crops

William is a second year PhD student at Rutgers University studying the potential benefits of native endophytic soil bacteria in alleviating abiotic stress and promoting growth in various commercial plant species. Abiotic stresses such as heat, drought, and salinity are all exacerbated by climate change, reducing the yield and quality of crops. William’s research explores the diverse beneficial compounds produced by native soil bacteria and how they can be used to reduce plant stress in field applications through the development of inoculants and biofertilizers.

Increasing Temperature on Flower Development of Northern Highbush Blueberry

Sarah is a graduate student at West Virginia University studying the effects of abiotic stresses on horticultural crop production. Her research utilizes controlled environments (greenhouse and growth chambers) to manipulate abiotic factors such as carbon dioxide, temperature and water to examine the effect of those combinatory factors on growth and development of horticultural crops, and ultimately to decipher the mechanisms of plants’ response to climate change. Sarah is particularly interested in the interaction of abiotic stresses on phenology at the phenotypic and genotypic level.

Integration of Hydrologic Modeling for Sustainable Water Reuse in Water-stressed Watersheds

Manashi is a second-year Ph.D. student in the University of Maryland (UMD) College Park Water Security and Sustainability Lab. She is a CONSERVE Scholar, working on sustainable water and food security. Manashi’s research focuses on sustainable water reuse in agricultural watersheds where high-quality water is not sufficient for irrigation due to ongoing climate variability and population growth. She uses hydrological modeling, GIS, and statistical analysis to solve problems that will help stakeholders involved in the implementation of water reuse programs.

Assessing Climate Perceptions and Developing Adaptation Resources for Small, Medium and Beginning Farms

Ruth is pursuing a Master's at the University of Maine after recently graduating with degrees in Biology and Global Studies from a small liberal arts school in Minnesota. This background, along with previous research and internship experiences, have peaked her interest in how agricultural research can be applied to sustainable community and farm development, and vice versa. Specifically, Ruth aims to ask questions about how smaller-scale growers can adapt and improve farming practices in the face of climate change while reducing detrimental impacts on the environment.

Climate Adaptation Strategies for Potato and Grain Systems

Brogan is a second year Masters student at the University of Maine, where she is using a crop simulation model to assess climate adaptation strategies for potato and grain systems. The project includes calibrating the crop simulation model for potato-barley production in Maine, using experimental field data. The model will then be used to assess the likely impacts of potential climate change and weather variability on crop yield, and evaluate risk-reduction strategies under various climate scenarios. Brogan is enthusiastic about the potential to explore long-term adaptive management with the use of process-based biophysical models.
