Red Knot Migration and Population Ecology

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.

Quantitative Turtle Analysis Project: Machine learning with turtles

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...

Asian Flyways Collaborative for Waterbirds (AFCoW)

The Asian Flyways Collaborative for Waterbirds (AFCoW) is a collaborative group effort that brings together research scientists engaged in understanding waterbird ecology in Eastern Asia. Due to the complexity of waterbird biology and unique threats to their populations in East Asia, we have established a voluntary international network of collaborators to promote advanced studies of large-scale...

Hazard and Risk of Anticoagulant Rodenticides to Predatory and Scavenging Wildlife

Invasive mammalian predators are the most damaging group of animals affecting global biodiversity. When introduced on remote islands, alien rodent species can devastate local biota and have been linked to approximately 30% of all extinctions. In addition, rodents can also consume and spoil crops, and serve as disease vectors that affect humans. Starting in the 20th century, rodenticides were...

Bird Habitat Needs in the Mississippi Alluvial Valley

Historically the Mississippi Alluvial Valley (MAV) was predominantly bottomland hardwood forest and most birds of conservation concern depend on bottomland hardwood forest. Past conservation planning has focused on habitat objectives with presumption that bird population goals would be met by habitat provision.

Monitoring Birds in National Parks of the Gulf Coast Network

The Challenge: Avian monitoring within the Gulf Coast Network of the National Park Service is challenged to provide valid quantitative data on bird populations within park boundaries with limited financial input. Thus, citizen science (volunteer) bird monitoring has been proposed to achieve reliable estimates of bird populations and to assess the effects of habitat change and temporal dynamics of...

Adaptive Management of Black Rails

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...

Rafinesque’s Mammals

The Challenge: Taxonomic nomenclature relies, in part, upon an accurate taxonomic history in order to establish the correct name for a taxon. Constantine S. Rafinesque (1783–1840), was a knowledgeable North American natural historian who was is responsible for describing and naming such iconic American mammals as the mule deer [Odocoileus hemionus (Rafinesque, 1817)] and the white-footed mouse...

Survival of the Least Fit: Incidence of Physical Trauma in a Wild Mammal Community

The Challenge: It has been generally considered that a severe injury to a wild mammal that seemingly limits its ability to forage for food or escape predators will almost certainly lead to that individual’s demise. Inspection of skeletons of wild caught small mammals, however, has revealed a surprising number of individuals with healed fractures of the skeletal bones―including the primary...

Diversity and Biogeography of Treeshrews

The Challenge: Treeshrews (order Scandentia) are small-bodied mammals endemic to South and Southeast Asia. Since it was first described in 1820, the Common Treeshrew (Tupaia glis) has had a complex taxonomic history that has led to widely variable estimates of diversity, misidentification of populations, and general confusion regarding it and closely related species. One result is that T. glis has...

Biodiversity of North American Mammals

The Challenge: Despite more than a century and a half of study, accurate understanding of the diversity North American mammalian species and the distribution of those species remains unrefined. Yet this understanding is essential for determining the conservation status of species, for mapping out potential disease reservoirs, and for understanding the response of species to habitat perturbation...

How Mammals Move: Locomotory Function in the Soricidae

The Challenge: The postcranial skeletons of mammals exhibit tremendous variation in form that partly relates to phylogeny (who a particular species is related to) and partly to locomotory function (how that species moves through its environment). Understanding the contributions of these two factors is important because phylogenetic characters assist in working out evolutionary relationships...
