Partly cloudy with a chance of mosquitoes: Developing a flexible approach to forecasting mosquito populations
Climate-induced shifts in mosquito phenology and population structure have important implications for the health of humans and wildlife. The timing and intensity of mosquito interactions with infected and susceptible hosts are a primary determinant of vector-borne disease dynamics. Like most ectotherms, rates of mosquito development and corresponding phenological patterns are expected to change un
Arsenic accumulation in Sonora Mud Turtles (Kinosternon sonoriense) in an unusual freshwater food web
Montezuma Well is an unusual fishless, spring-fed, desert wetland in central Arizona. Water in the wetland is naturally enriched with > 100 µg/l dissolved geogenic arsenic (As) and supports a simple aquatic food web dominated by a small number of endemic invertebrate species that achieve high abundances. Previous studies of As among various environmental compartments and organisms in Montezuma Wel
Genotypic clustering of H5N1 avian Influenza viruses in North America evaluated by ordination analysis
The introduction of HPAI H5N1 clade 2.3.4.4b viruses to North America in late 2021 resulted in avian influenza outbreaks in poultry, mortality events in many wild bird species, and spillover into many mammalian species. Reassortment events with North American low pathogenic virus were identified as early as February 2022 and over 100 genotypes have been characterized. Such diversity increases the

Expanding Distribution of Chronic Wasting Disease
Chronic wasting disease (CWD) has been detected in 35 US states and five Canadian provinces in free-ranging cervids and/or commercial captive cervid facilities. CWD has been detected in free-ranging cervids in 35 states and four provinces and in captive cervid facilities in 22 states and three provinces.
Diagnostic Case Submission Guidelines
Standard submission criteria for federal, state, and tribal natural resource agency partners The National Wildlife Health Center (NWHC) conducts laboratory diagnostics to determine causes of wildlife morbidity and mortality events. The following guidelines are used to determine which cases we accept for diagnostic evaluation. NWHC only accepts submissions from, or in coordination with, federal...
Interagency coordination on coral health
The USGS National Wildlife Health Center (NWHC) supports coral health through participation in two interagency coordination bodies, the Florida Disturbance Advisory Committee, which is focused on joint management of the Florida Coral Reef Tract, and the U.S. Coral Reef Task Force, which is focused on joint management of reef resources within U.S. Territories in both the Caribbean and Pacific.
