American pikas (Ochotona princeps) are small lagomorphs that live in mountainous talus areas of western North America. Studies on the histopathology of American pikas are limited. This report summarizes the clinical histories, and gross and histologic findings of 12 American pikas, including nine captive and three wild animals. Death was often attributed to stress (transport, handling, and anesthesia) with few to no premonitory clinical signs. Two cases died due to infection: one had bacterial pyogranulomatous dermatitis, cellulitis, and lymphadenitis with sepsis; the other case had fungal necrotizing colitis. Incidental parasite infections included sarcocystosis, nematodiasis (oxyurids), and ectoparasitism. Most...

This dataset contains Sr:Ca of water and fin ray samples of native fish to evaluate upstream fish passage through a navigation lock in the Des Plaines River (Brandon Roads Lock and Dam). Fin ray samples from several native fish taxa (catostomids, ictalurids, centrarchids, and lepisosteids) were collected in two river reaches downstream of Brandon Roads Lock and Dam, and in a river reach upstream of Brandon Roads Lock and Dam. Fin ray Sr:Ca derived from microchemistry analyses of fin ray materials from a laser ablation transect is included as both edge values and entire transect (including edge). Edge values of Sr:Ca were used to characterize chemical signatures of residency for each of the rivers and make comparisons...

The Yǻyaguak (Mariana Swiftlet; Aerodramus bartschi) is an endangered cave-roosting species native to Guam and southern Mariana Islands, Micronesia. On May 24-25, 2023, Guam was hit by the category-4 Typhoon Mawar, which brought wide-spread destruction to the island. Approximately 6 weeks prior to the typhoon in April 2023 we conducted surveys of the three known colonies of Yǻyaguak at Mahlac, Maemong, and Fachi caves. This April 2023 pre-Mawar survey provided a baseline population estimate prior to Typhoon Mawar’s landfall. In July 2023, we re-surveyed the caves to estimate colony size and assess whether the cave colonies experienced significant declines in the immediate aftermath of the storm. In November 2023,...

These data represent a case study on managing the invasive brown treesnake (Boiga irregularis) on Guam within a 5 ha snake enclosure located on Northern Guam. The site code (NWFN or North West Field North) reflects a location on Andersen Air Force Base, Northern Guam, which has been a study site for close to two decades. The experimental process followed an adaptive resource management process to develop an integrated pest management strategy for either eradication or validating whether extant species (rodents, lizards, and birds) would respond to population suppression over a 6 year removal effort. The program included an evaluation of the Aerial Delivery System, as well as a comparison of bait species (quail,...

Data includes grass carp position and sampling data from 2020 to 2022. We used grass carp that were implanted with acoustic transmitters. The position data was generated in Fathom Position from receivers that composed several VEMCO Positioning Systems (VPS). We also queried the Great Lakes Acoustic Telemetry Observation Network (GLATOS) to obtain non-VPS position detections from receivers made from multiple projects across Lake Erie and associated tributaries. Sampling data was downloaded from the grass carp capture database hosted on ArcGIS Online These data contain information such as location of event, time gears were deployed and retrieved, and number of grass carp caught.

Eggshells of 13 waterbird species were divided in half longitudinally and the outer eggshell membrane was removed from one of the halves. Eggshell thickness was measured for both eggshell halves, both with and without the outer eggshell membrane. The eggshell membrane thickness was calculated by taking the difference between the two thickness measurements. These data support the following publication: Santolo, G.M., Peterson, S.H., Cooney, B., Hartman, C.A., Herzog, M.P. and Ackerman, J.T., 2024. Eggshell membrane thickness and its contribution to total eggshell thickness for 13 waterbird species. The Wilson Journal of Ornithology. https://doi.org/10.1676/23-00017

Mid-sized mammals (i.e., mesomammals) fulfill important ecological roles, serving as essential scavengers, predators, pollinators, and seed dispersers in the ecosystems they inhabit. Consequently, declines in mesomammal populations have the potential to disrupt ecological processes and degrade ecosystems. However, ecosystems characterized by high functional redundancy, where multiple species can fulfill similar ecological roles, may be less impacted by the loss of mesomammals and other vertebrates. The Greater Everglades Ecosystem in southern Florida is a historically biodiverse region that has recently been impacted by multiple anthropogenic threats, most notably the introduction of the Burmese python (Python bivittatus)....

This layer represents fundamentally suitable and unsuitable habitat for freshwater mussels in the Meramec Basin as modeled by these authors on May 17, 2017 based on spatial data ranging from 1990 to 2014. Identification of habitat characteristics associated with the presence of freshwater mussels is challenging but crucial for the conservation of this declining fauna. Most mussel species are found in multi-species assemblages suggesting that physical factors influence presence similarly across species. In lotic environments, geomorphic and hydraulic characteristics appear to be important factors for predicting mussel presence. We used maximum entropy (MaxEnt) modeling to evaluate hydrogeomorphic variables associated...

These data contain the results from the North American Bat Monitoring Program's (NABat) species distribution model (SDM) for the northern long-eared bat (Myotis septentrionalis). The provided tabular data includes predictions (with upper and lower confidence intervals) for northern long-eared bat occupancy probabilities (which represent the probability of presence) based on data from the entire summer season (May 1-August 31), averaged from 2017-2022, in each NABat grid cell (5km x 5km scale) across the range of the species. Specifically, predictions represent occupancy probabilities in the pre-volancy season in the summer (May 1–July 15), i.e., the period of time before juveniles can fly and become detectable by...

Risk assessments describe the risk of a species’ invasion in a location, and many risk assessments have been produced by different institutions for various reasons. However, information is sporadically located online, increasing the difficulty of developing comprehensive lists of species with risk assessments or comparing assessment results across species in locations of interest. Therefore, we aggregated species risk assessments by searching information systems and conducting a literature review. The methods for data aggregation are explained in the larger work citation (Dean et al. 2024). The present dataset documents risk assessments available at different spatial scales (e.g., territory, state, region, nation)...
