Decision Science and Quantitative Methods

The Disease Decision Analysis and Research group is a multi-disciplinary team based out of the Eastern Ecological Science Center whose strengths are in ecology, decision sciences and quantitative modeling.

Southeast Asia has long been the epicenter of AIV emergence. However, as demonstrated by H5NX, these viruses can quickly reach global spread and have significant impacts on poultry production and human health. We have two ongoing efforts funded by the National Science Foundation to help improve our understanding of AIV emergence, spread, and transmission in today’s rapidly changing landscape.

Eastern Ecological Science Center biologists are studying migration and population ecology of the rufa red knot, a bird species that is dependent on horseshoe crab eggs to complete its trans-hemispheric migration. The birds' spring migration is timed with spawning of horseshoe crabs because the eggs are the perfect food for a migrating red knot.

Collaboration between the world-class expertise of USGS scientists, the Atlantic States Marine Fisheries Commission’s Science Program, and state and federal fishery agencies demonstrates the power of partnerships to solve seemingly-insurmountable problems in sustainable and cooperative management of Atlantic coastal fisheries.

The USGS Amphibian Research and Monitoring Initiative (ARMI) is designed to determine where populations of amphibians are present, to monitor specific apex populations, and to investigate potential causes of amphibian declines, diseases, and malformations. The Northeast Region of ARMI encompasses thirteen states (Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New...

The Eastern Ecological Science Center is working closely with federal, state, and tribal partners to help inform decisions that reduce the risk of SARS-CoV-2 transmission from humans to North American wildlife, including bats.

Eastern Ecological Science Center adds the decision analytical skill set to the existing body of USGS expertise on Chronic Wasting Disease (CWD), in support of our sister DOI agencies.

The Quantitative Turtle Analysis Project (QTAP) was created in 2019 with the goal of investigating how machine learning can be used to study wildlife populations using capture-recapture methods. QTAP has specifically been researching how digital images of the eastern box turtle (Terrapene carolina carolina) can be used by automated programs to recognize unique individual turtles, in place of a...

US Fish and Wildlife Service completed a regional assessment of salt marsh integrity (SMI) on 15 National Wildlife Refuges/Refuge Complexes in the northeastern US. Developed within a structured decision making (SDM) framework, the SMI assessment provides essential baseline data on salt marsh condition relative to regional management objectives. These data now provide the basis for applying the SDM...

Wildlife forestry is management of forest resources, within sites and across landscapes, to provide sustainable, desirable habitat conditions for all forest-dependent (silvicolous) fauna while concurrently yielding economically viable, quality timber products. In practice, however, management decisions associated with wildlife forestry often reflect a desire to provide suitable habitat for rare...

The Black Rail (Laterallus jamaicensis) is the most secretive of the secretive marsh birds and few aspects of its life history and ecology are well understood. The Eastern Black Rail subspecies (L. j. jamaicensis) is listed as endangered in five states along the Atlantic Coast and has been proposed as Threatened under the Endangered Species Act and is under review for federal listing. Historical...

The purpose of this work is to advance our understanding of how coastal wetland responses to SLR within the conterminous United States are likely to vary as a function of local, regional, and macroscale drivers, including climate. Based on our interactions with managers and decision makers, as well as our knowledge of the current state of the science, we propose to (a) conduct a national synoptic...
