Data from 2018 Experiment on Effects of Temperature on Survival and Growth of Juvenile Lost River Suckers (Deltistes luxatus) naturally exposed to Ichthyobodo spp

Data included in this data set are for an experiment conducted in 2018. Data were collected on survival, growth, food consumption, and Ichthyobodo copy numbers of Lost River suckers exposed to five different temperature groups. There are five levels of data.

Cyanobacterial toxin effects on inflammatory response of human toll-like receptors (TLRs)

Various stressors including temperature, environmental chemicals and toxins can have profound impacts on immunity to pathogens. It is believed that increased eutrophication near rivers and lakes coupled with climate change are predicted to lead to increased algal blooms. Currently, the effects of cyanobacterial toxins on disease resistance in mammals is a largely unexplored area of research....

Fish and Climate Change Database (FiCli)

Inland fishes are important to communities worldwide and provide many ecosystem services, such as recreational opportunities, subsistence fishing, and commercial income. To support climate adaptation for fisheries management across the globe, the USGS Alaska, Missouri, and North Carolina Cooperative Research Units developed an interactive database, ...

Data on blood cells of the collector urchin, Tripneustes gratilla

Echinoderms such as urchins are important in marine ecosystems, particularly as grazers, and unhealthy urchins can have important ecological implications. For instance, unexplained mortalities of Diadema sp. in the Caribbean were followed by algal overgrowth and subsequent collapse of coral reef ecosystems. Unfortunately few tools exist to evaluate echinoderm health making management of mo...

Skin mycobiomes of eastern North American bats

North American bats have experienced catastrophic population declines from white-nose syndrome (WNS), a fungal disease caused by Pseudogymnoascus destructans (Pd). Although Pd can infect many hibernating bat species, population-level impacts of WNS vary by host species. Microbial skin assemblages, including the fungal component (mycobiome), can influence host resistance to inf

Effects of early life stage exposure of largemouth bass to atrazine or a model estrogen (17α-ethinylestradiol)

Largemouth base histological development and transcriptomic changes in gonad tissue after early life stage exposure to Atrazine (1-Chloro-3-ethylamino-5-isopropylamino-2,4,6-triazine) or the model estrogen 17α-ethinylestradiol.

Immunological histopathology of American kestrels (Falco sparverius) exposed in ovo to two persistent organic pollutants -- SCCPs and TBBPA-BDBPE

This work is part of a study of the immunological effects of exposure to alternative flame retardants in avian species. For the pathology portion of the study, spleens and bursas from American kestrels (Falco sparverius) exposed by egg injection to varying doses of short-chain chlorinated paraffins (SCCPs) and the flame retardant TBBPA-BDBPE were examined microscopically for architectur

Immunological histopathology of American kestrels (Falco sparverius) exposed to the flame retardant isopropyl triphenyl phosphate

This work is part of a study of the immunological effects of exposure to alternative flame retardants in avian species. For the pathology portion of the study, hatchling American kestrels (Falco sparverius) were exposed to the flame retardant isopropyl triphenyl phosphate (ITP) and then challenged with a synthetic analogue of viral double-stranded RNA, polyinosinic:polycytidylic aci

Necropsy reference number and summary collection information for Washington state population of northern sea otters examined during 1989-2010

Morbillivirus epidemics in marine mammals first gained prominence in 1988 when an outbreak of phocine distemper virus (PDV) occurred in European harbor seals (Phoca vitulina vitulina). Prior to 2001, all serosurveys for morbilliviruses in sea otters (Enhydra lutris) in California, Washington and Alaska documented a 0% seroprevalence. The first published serodetections of morbi

Fleas collected from black-tailed prairie dog burrows in 2016 and 2017

The data are a list of the number and species of fleas that were collected from black-tailed prairie dog burrows in Montana, North Dakota, South Dakota, Colorado, and New Mexico. Fleas were collected by swabbing ~100 burrows at 3 sites at each of 6 sites. Burrows were sampled twice each summer during 2016 and 2017.

Histopathology of bearded dragons (Pogona vitticeps) exposed to Nannizziopsis guarroi

This work is part of a study demonstrating that the fungus Nannizziopsis guarroi is the cause of the disease known as yellow fungus disease in bearded dragons (Pogona vitticeps) by fulfilling Koch’s postulates. In this study, bearded dragons were exposed to N. guarroi to assess gross and microscopic lesion development and the ability to re-culture the fungus from infected sites. At

Southwestern Willow Flycatcher Habitat Viewer

The Flycatcher Habitat Viewer was developed to meet the needs of organizations by providing maps of predicted flycatcher breeding habitat throughout its range. Maps are provided from 2013 to present and cover 57 satellite scenes. Maps identify predicted flycatcher habitat based upon the amount of green vegetation within a 120-m radius of each cell, and the size of floodplain within a 360-m...
