American Black Duck and Threat of Avian Influenza

The Challenge: The genomic revolution is giving wildlife biologists new tools to assess the role of wildlife in spreading diseases that affect human populations.   Peptide arrays are a high throughput technology that gives unprecedented breadth and depth of information about the immune system.  We are using peptide arrays to assess the immune responses of Chesapeake Bay waterfowl to avian...

Disease Resistance of Wildlife Species: how the immune system evolves and adapts

The Challenge: In an era when emerging infectious diseases are steadily increasing, human populations are exposed to virulent new pathogens.  Insight into the human system can be gained from understanding the variety of immune adaptations of wildlife species.  The vertebrate immune system is not static.  Rather, it involves in response to the environment.

Sustainably Designed Trails: Recent Recreation Ecology Findings on Design Factors Affecting Soil Loss

The Challenge: Achieving conservation objectives in protected natural areas requires the ability to sustain visitation while avoiding or minimizing adverse environmental impacts. Trails are an essential infrastructure component that limits resource impacts by concentrating use on hardened treads designed and maintained to sustain traffic. This is particularly challenging when visitation is...

Shoreline Changes and Impacts to Natural Resources in Chesapeake Bay

The Challenge: Climate change and sea level rise are expected to affect many miles of shoreline in the Chesapeake Bay and elsewhere along the Atlantic Coast in the coming years. In this scenario, federal and state agencies need to make more detailed assessments of how different watersheds and shoreline types might influence an array of ecosystem functions and components. Recently, most states...

A Vaccination Program to Protect Endangered Whooping Cranes from Encephalitis Virus

The Challenge: In eastern North America there is a viral disease called Eastern Equine Encephalitis, or EEE. This virus is transmitted among native bird species by the mosquito, Culiseta melanura, but does not cause disease in these passerine species. However, the virus is capable of causing severe disease or death in horses, some game bird species, humans and whooping cranes. In the fall of...

Use of Structured Decision Making to Optimize Salt Marsh Management Decisions at Northeastern National Wildlife Refuges

The Challenge: The U.S. Fish and Wildlife Service (FWS) needs tools to inform decisions regarding the management and restoration of salt marsh ecosystems on northeastern National Wildlife Refuges. Previously, we developed a structured decision making (SDM) framework for optimizing refuge management decisions. This SDM framework served as the foundation for FWS to implement a consistent...

Avian Influenza Surveillance in Waterfowl in the Atlantic Flyway

The Challenge: In December of 2014, a novel strain of highly pathogenic avian influenza (HPAI) caused an outbreak in poultry on the West coast of the United States. From there, the virus progressed steadily eastward, causing $3.3 billion in economic losses in addition to 50 million chickens or turkeys dying or being depopulated. While the primary mode of spread appears to be via the poultry...

Research and Management of Informal (Visitor-Created) Trails in Protected Areas

The Challenge: The proliferation and degradation of visitor-created “informal” trails in protected areas can be a vexing management issue for land managers. Formal trail systems never provide access to all locations required by visitors seeking to engage in a variety of appropriate recreational activities. Traveling off-trail may be necessary to engage in activities such as nature study,...

Coastal Salt Marsh Management Along the Atlantic

The Challenge: A number of coastal states have been altering marshes for mosquito control since the early 1900s, but for the past four decades, changes have been made in the methods used to alter high-marsh environments. However, in most states, research and monitoring activities are still needed to inform the management methods employed. Although modern Open Marsh Water Management (OMWM)...

Pathogens in the Aquatic Environment – Waterfowl, Avian Influenza

The Challenge: Changes in aquatic ecosystems related to climate change phenomena or other anthropogenically based environmental stressors have significant impact on the dynamics of the host-pathogen-environment relationship, often with surprising results. Therefore, biosurveillance of the aquatic environment for pathogens of significance to aquatic and terrestrial wildlife, as well as to...

USGS Wild Bird Avian Influenza Program – Studies from Endemic Regions of Eurasia

The Challenge: Following outbreaks of highly pathogenic avian influenza (HPAI) in Eurasia, many researchers have attempted to determine how this virus spreads across the landscape. Unfortunately, prior to this work, most studies on HPAI movements were based on virology data alone, and no information on host ecology. Beginning in 2007, USGS Patuxent Wildlife Research Center (PWRC) and Western...

Tracking Domestic Ducks through the Market Chain in China via Telemetry

The Challenge: Highly pathogenic avian influenza viruses (HPAI) of certain subtypes primarily infect poultry, causing disease outbreaks and negative socio-economic impacts on poultry farming depending on the characteristics of biosecurity and the virus strain. HPAI viruses seem to be adapted to artificial ecosystems including poultry farming, free-ranging duck production, and live bird markets...
