Intracoelomic implantation of electronic tags has become a common method in fishery research, but rarely are fish examined by scientists after release to understand the extent that surgical incisions have healed. Walleye (Sander vitreus) are a valuable, highly-exploited fishery resource in the Laurentian Great Lakes. Here, fishery capture of walleye with internal acoustic transmitters combined with a high reward program provided multiple opportunities to examine photographs and quantify the status of surgical incisions. Walleye (n=926) from reef and river spawning populations in Lake Erie and Lake Huron were implanted with acoustic transmitters during spring spawning events from 2011 to 2016. Incisions were closed...
The data set contains results for nine serum biochemistries in molting Pacific black brant (Branta bernicla nigricans). These data were used to calculate reference intervals (sometimes referred to as normal values) for the nine serum biochemistries. All brant were after-hatch year. All samples were collected in 2006 and 2007 in the Teshekpuk Lake Special Area, Alaska.

Macrhybopsis reproduction and propagule traits were studied in the laboratory using two temperature regimes and three hormone treatments and which methods produced the most spawns. Only sicklefin chub (M. meeki) spawned successfully although sturgeon chub (M. gelida) released unfertilized eggs. All temperature and hormone treatments produced M. meeki spawns, but two treatments had similar success rates at 44 and 43%, consisting of a constant daily temperature with no hormone added, or daily temperature fluctuations with hormone added to the water. Spawns consisted of multiple successful demersal circular swimming spawning embraces interspersed with circular swims without embraces. The most spawns observed for one...

The broadly shared information needs for grassland managers in the North Central region to meet conservation goals in a changing climate are presented and ranked as highly relevant, somewhat relevant, or not relevant for federal, state, tribal, and non-governmental grassland-managing entities.
Bats occupying hibernacula during summer months may play an important role in the epidemiology of white-nose syndrome (WNS). For example, bats exposed to viable Pseudogymnoascus destructans (Pd), the causative agent of WNS, in late summer could spread the fungus by transmitting it to other bats or to other locations suitable for establishment of new environmental reservoirs. To explore risks for transmission of Pd during the non-hibernal season, we screened bats using hibernacula between July 18 to August 22, 2012 and associated environmental samples for presence of Pd. Study sites within the eastern United States included six hibernacula known to harbor Pd and two hibernacula in which bats with WNS had not been...

This dataset includes microsomal EROD data from an assay done with liver samples from several fish species that are found in Arizona at sites that are being assessed for PBDE contamination. The data was created in September and October 2016.

This dataset is comprised of eight files related to salt marsh monitoring data or measures of of human disturbance (i.e. human impacts in terms of physical, chemical, and land-use stressors) collected at 33 marsh study units (MSUs) in five National Parks within the NPS Northeast Coastal and Barrier Network (NCBN) along the northeastern coast of the US. Two files contain data related to the species and coverage of salt marsh vegetation observed in MSUs (1 data file, 1 definitions file). Two files contain data related to the species and abundance of nekton collected from creeks, pools and ditches in MSUs (1 data file, 1 definitions file). Two files contain data related to the height of key salt marsh vegetation species...
To investigate the role of migratory birds in the dissemination of West Nile virus (WNV), we measured the prevalence of infectious WNV and specific WNV neutralizing antibodies in birds, principally Passeriformes, during spring and fall migrations in the Atlantic and Mississippi flyways from 2001-2003. Blood samples were obtained from 13,403 birds, representing 133 species. Specific WNV neutralizing antibody was detected in 254 resident and migratory birds, representing 39 species, and was most commonly detected in northern cardinals ( Cardinalis cardinalis ) (9.8%, N = 762) and gray catbirds ( Dumetella carolinensis ) (3.2%, N = 3188). West Nile virus viremias were detected in 19 birds, including 8 gray catbirds,...
During 2010 to 2013, waterbird mortality surveillance programs used a shared protocol for shoreline walking surveys performed June to November at three areas in northern Lake Michigan. In 2010 and 2012, 1244 total carcasses (0.8 dead bird/km walked) and 2399 total carcasses (1.2 dead birds/km walked), respectively, were detected. Fewer carcasses were detected in 2011 (353 total carcasses, 0.2 dead bird/km walked) and 2013 (451 total carcasses, 0.3 dead bird/km walked). During 3 years, peak detection of carcasses occurred in October and involved primarily migratory diving and fish-eating birds, including long-tailed ducks (Clangula hyemalis; 2010), common loons (Gavia immer; 2012), and red-breasted mergansers (Mergus...

Monkeypox virus (MPXV) is a zoonotic disease endemic in Central and West Africa and is the most virulent orthopoxvirus affecting humans since the eradication of variola virus (VARV). In order to assess their reservoir potential, wild-caught rope squirrels were experimentally infected via intranasal and intradermal exposure with a recombinant MPXV strain from Central Africa engineered to express the luciferase gene. After infection, we monitored viral replication via in vivo bioluminescent imaging and viral shedding via culture and PCR. MPXV infection in African rope squirrels caused mortality and moderate to severe morbidity, with clinical signs including pox lesions in the skin, eyes, mouth and nose, dyspnea, and...

In 2010, a mass mortality of pufferfish in Hawaii was dominated by Arothron hispidus showing aberrant neurological behaviors. Using pathology, toxinology, and field surveys, we implicated a series of novel, polar, marine toxins as a likely cause of this mass mortality. Our findings are striking in that 1) a marine toxin was associated with a kill of a fish species that is, itself, toxic; 2) we provide a plausible mechanism to explain clinical signs of affected fish, and 3) this epizootic likely depleted puffer populations. Whilst our data are compelling, we did not synthesize the toxin de-novo, we were unable to categorically prove that the polar toxins caused mortality or that they were metabolites of an undefined...
(i) Severe perkinsea data was based on the observation of characteristic gross and microscopic lesions and the morphological identification of Perkinsea organisms within the lesions. Necropsies and gross evaluation of carcasses were carried out under a dissecting microscope. Specimen were collected and submitted to the NWHC as part of mortality investigations and collection of specimen from apparently healthy populations as part of ongoing amphibian health monitoring. (ii) Epidemiological information was compiled from each anuran sample, including the detection type (mortality event or health monitoring study), location (state and county), anuran species reported in the event, life-stage of species reported in the...

In 2014, the USGS Lake Erie Biological Station participated in the Coordinated Science and Monitoring Initiative (CMSI) program, a program founded by the U.S. Environmental Protection Agency (EPA) and Environment Canada in the 1990s as a means to focus collaborative research attention on one of the five Great Lakes each year (on a rotating schedule) as a means to increase scientific knowledge for Great Lakes restoration. The Lake Erie survey examined the food web across a nearshore to offshore gradient, matching the sampling design the preceding USGS studies of the other four Great Lakes (2010-2013). We sampled all trophic levels in all three lake basins across multiple seasons in order to determine nutrient availability...

The Kittlitz’s Murrelet (Brachyramphus brevirostris) is a small, non-colonial seabird endemic to marine waters of Alaska and eastern Russia that may have experienced significant population decline in recent decades, in part because of low reproductive success and terrestrial threats. Although recent studies have shed new light on Kittlitz’s Murrelet nesting habitat in a few discrete areas, the location and extent of other possible nesting areas throughout most of its range remains unclear. This data release consists of (1) nest locations for the Kittlitz’s Murrelet (2) potential Kittlitz’s Murrelet nesting habitat. These data support the following publication (available online early): Jonathan J. Felis, Michelle...
