Science and Products
The Challenge: Disease risk modeling can be an important tool for identifying areas of high transmission risk within and between animal populations, allowing for strategic allocation of limited resources for disease surveillance and prevention. Acquiring a spatial understanding of the distributions of high risk populations is a critical first step in developing predictive disease transmission...
The Challenge: The susceptibility and pathogenesis of highly pathogenic avian influenza virus (HPAI) has not been characterized in numerous duck species, especially diving ducks (genera Melanitta, Aythya, and Oxyura), some of which migrate across the continental US. The few studies available (on Tufted duck, Aythya fuligula) suggest that they may shed high amounts of virus, but it is unclear...
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...
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...
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)...
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...
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...
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...
The Challenge: For several decades, the US Army Corps of Engineers, along with numerous state and federal partners, have been creating and restoring islands with dredged materials from navigation channels in the Bay. Natural resources management goals have guided restoration plans for these islands since the mid 1990’s. The USGS Patuxent Wildlife Research Center has been the only USGS science...
The Challenge: Concern has been raised over productivity of two important tern species that have colonized Poplar Island Environmental Restoration Project (PIERP): the Maryland state-listed Least Tern (Sternula antillarum) and Common Tern (Sterna hirundo). Over the 14 year monitoring period at PIERP (beginning 2002), hatching and fledging success of these species has been variable, believed to...
Using Advanced Technology to Enhance Research at the Patuxent Wildlife Research Center (PWRC) - a Public-Private Partnership
The Challenge: Threats such as habitat loss, increased severity of storm events, and emerging diseases are affecting wildlife populations, with particular concern for threatened and migratory species. Surveys for measuring populations and breeding productivity for various species have been utilized for many years; however, they can be intrusive leading to aggressive behavior of adults or even...

The aerosphere as a network connector of organisms and their diseases
Aeroecological processes, especially powered flight of animals, can rapidly connect biological communities across the globe. This can have profound consequences for evolutionary diversification, energy and nutrient transfers, and the spread of infectious diseases. The latter is of particular consequence for human populations, since migratory birds...Ross, Jeremy D.; Bridge, Eli S.; Prosser, Diann J.; Takekawa, John Y.
Species distribution modeling in regions of high need and limited data: waterfowl of China
BackgroundA number of conservation and societal issues require understanding how species are distributed on the landscape, yet ecologists are often faced with a lack of data to develop models at the resolution and extent desired, resulting in inefficient use of conservation resources. Such a situation presented itself in our attempt to develop...Prosser, Diann J.; Ding, Changqing; Erwin, R. Michael; Mundkur, Taej; Sullivan, Jeffery D.; Ellis, Erle C.
High altitude flights by ruddy shelduck Tadorna ferruginea during trans-Himalayan migrations
Birds that migrate across high altitude mountain ranges are faced with the challenge of maintaining vigorous exercise in environments with limited oxygen. Ruddy shelducks are known to use wintering grounds south of the Tibetan Plateau at sea level and breeding grounds north of Himalayan mountain range. Therefore, it is likely these shelducks are...Parr, N.; Bearhop, S.; Douglas, David C.; Takekawa, J.Y.; Prosser, Diann J.; Newman, S.H.; Perry, W.M.; Balachandran, S.; Witt, M.J.; Hou, Y.; Luo, Z.; Hawkes, L.A.
Surveillance for highly pathogenic influenza A viruses in California during 2014–2015 provides insights into viral evolutionary pathways and the spatiotemporal extent of viruses in the Pacific Americas Flyway
We used surveillance data collected in California before, concurrent with, and subsequent to an outbreak of highly pathogenic (HP) clade 126.96.36.199 influenza A viruses (IAVs) in 2014–2015 to (i) evaluate IAV prevalence in waterfowl, (ii) assess the evidence for spill-over infections in marine mammals and (iii) genetically characterize low-pathogenic...Ramey, Andy M.; Hill, Nichola J.; Cline, Troy; Plancarte, Magdalena; De La Cruz, Susan; Casazza, Michael L.; Ackerman, Joshua T.; Fleskes, Joseph; Vickers, T.

Low pathogenic avian influenza viruses in wild migratory waterfowl in a region of high poultry production, Delmarva, Maryland
Migratory waterfowl are natural reservoirs for low pathogenic avian influenza viruses (AIVs) and may contribute to the long-distance dispersal of these pathogens as well as spillover into domestic bird populations. Surveillance for AIVs is critical to assessing risks for potential spread of these viruses among wild and domestic bird populations....Prosser, Diann J.; Densmore, Christine L.; Hindman, Larry J.; Iwanowicz, Deborah; Ottinger, Christopher A.; Iwanowicz, Luke R. ; Driscoll, Cindy P.; Nagel, Jessica L.
Chewing lice of swan geese (Anser cygnoides): New host-parasite associations
Chewing lice (Phthiraptera) that parasitize the globally threatened swan goose Anser cygnoides have been long recognized since the early 19th century, but those records were probably biased towards sampling of captive or domestic geese due to the small population size and limited distribution of its wild hosts. To better understand the...Choi, Chang-Yong; Takekawa, John Y.; Prosser, Diann J.; Smith, Lacy M.; Ely, Craig R.; Fox, Anthony D.; Cao, Lei; Wang, Xin; Batbayar, Nyambayar; Natsagdorj, Tseveenmayadag; Xiao, Xiangming
