These data were compiled for a manuscript in which 1) we develop a water temperature model for the major river segments and tributaries of the Colorado River basin, including the Colorado, Green, Yampa, White, and San Juan rivers; 2) we link modeled water temperature to fish population data to predict the probability native and nonnative species will be common in the future in a warming climate; and 3) assess the degree to which dams create thermal discontinuity in summer in river segments across the western US. Per goal #1, we developed a water temperature model using data spanning 1985-2015 that predicts water temperature every 1 mile (1.6-km) in rivers both now and in the future due to the potential influence...
This Benthic Invertebrate Community Analysis dataset, a conceptual subgroup of the Lake Erie Ecological Investigations (LEEI) dataset, focuses on the benthic invertebrates sampled at Areas of Concern (AOCs) on Lake Erie. Per the Quality Assurance Project Plan (QAPP), the invertebrate samples were taken from sediments remaining from the sediment analysis. Identification of the invertebrates was completed by the same invertebrate taxonomist for both the 1998-2000 evaluation and 1986-87 historical evaluation (Smith et al. 1994) for increased consistency. Oligochaetes were identified to species if possible, chironomids were identified to genus, as adult specimens are needed for specific identification, and other taxa...
This simple assessment raster is used to answer management questions (MQs) about where change agents (CAs) overlap with BLM high biodiversity sites (HBS) in the Central Great Basin and Range Ecoregion. This is a basic footprint assessment of anthropogenic features (urban development, roads, etc) intersect with the areas of HBS. The HBS were derived from source data characterizing locations with concentrated at-risk biodiversity or existing source data of a prioritization exercise that identified areas of high conservation significance. It does not model actual response or condition of the HBS to the CAs. The data intersects two primary classes of information: The CAs consist of 19 classes which represent different...
Chinook salmon (Oncorhynchus tshawytscha) are an anadromous fish species that migrate through, feed in, and spawn in the Yukon River Lowlands - Kuskokwim Mountains - Lime Hills. This dataset provides the current (2013) spatial distribution of chinook salmon within the REA study area for the analysis of chinook salmon as an Aquatic Fine-Filter Conservation Element. This dataset was derived by clipping the chinook salmon distribution from the Anadromous Waters Catalog to the boundaries of the study area for this REA. The Anadromous Waters Catalog is developed and maintained by the Alaska Department of Fish and Game. It includes all waters known to include populations of anadromous fish but does not differentiate by...
Fish occurrence data have been collected within the North Slope study area, however most of these data are presently available only in non-digitized format (e.g., hardcopies, inventory reports, unpublished data, etc.). Due to the lack of spatial data available, Alaska Natural Heritage Program began collaboration with BLM fisheries biologists to assist with their efforts to enter these fish distribution datasets into the geodatabase RipFish that was developed and is maintained by BLM. Our contribution to this database serves as a final product for the Aquatic Fine-Filter CEs for the Rapid Ecoregional Assessment and will allow managers to readily have access to fish distribution data and conduct future spatial analyses....
This dataset shows the distribution of invasive aquatic species compiled from the USGS nonindigenous aquatic species database and national institute of invasive species science database. These species include asian clams, Quagga mussels, and zebra mussels.
Although future roads are included in the long-term LCM, we conducted separate spatial analyses intersecting the future layers with our fish distributions to identify the projects or watersheds with the potential to impact fish species of conservation concern. Four datasets were used to represent future road construction in the study area: preferred routes to Nome, Umiat, and Ambler; and proposed forestry roads. These roads were intersected with the distributions of Dolly Varden. The anadromous Dolly Varden habitat distribution and modeled resident Dolly Varden habitat distribution for the 2060s were combined into a single distribution for this analysis. Road intersections were highest for Dolly Varden because Dolly...
Alaska's abundant, remote, and predominantly pristine freshwater fish habitats are largely unexplored and undocumented. To begin filling these vast information gaps, the Alaska Freshwater Fish Inventory Database (AFFID) houses freshwater fish (anadromous and resident)-occurrence data sets compiled from a variety of sources. Most records in the AFFID come from Alaska Department of Fish and Game (ADFG) fish and aquatic habitat inventories. However, the AFFID also includes selected recent fish-occurrence data sets from ADFG Fish Resource Permit fish-collection reports submitted to ADFG by other organizations (agencies, consulting firms, non-governmental organizations, and individuals) who collect fish for scientific...
This dataset provides an estimate of aquatic intactness (i.e. condition or integrity) across the Bon Cuthrout Trout C's potential distribution. Current aquatic intactness estimates are based on the extent to which human impacts such as water demand, agriculture, urban development, natural resource extraction, dams, diversions, and alterations have disrupted the hydrology, water quality, and habitat quality of aquatic systems across the state of Utah and the Colorado Plateau. Aquatic intactness values will be high in areas where these impacts are low.This HUC6 (12-Digit NHD Hydrologic Unit Code) resolution dataset was created for the Colorado Plateau REA stepdown analysis using the open-source logic modeling framework...

This report presents updated information about subsistence uses of fish, wildlife, and plant resources in 5 communities of southcentral Alaska -- Iliamna, Newhalen, Nondalton, Pedro Bay, and Port Alsworth. The Division of Subsistence of the Alaska Department of Fish and Game conducted the study in collaboration with the National Park Service and Stephen R. Braund & Associates. The Pebble Project is a proposed open pit mine located 18 miles to the northwest of Iliamna and 18 miles southwest of Nondalton. The potential development of the mine requires updated baseline information about subsistence harvests and uses. Information was collected through systematic household surveys and mapping interviews. Scoping meetings...

This report presents updated information about subsistence uses of fish, wildlife, and plant resources in 5 communities of southcentral Alaska - Igiugig, Kokhanok, Koliganek, Levelock, and New Stuyahok. The Division of Subsistence of the Alaska Department of Fish and Game conducted the study in collaboration with Stephen R. Braund & Associates. Phase I of this study took place in the communities of Iliamna, Newhalen, Nondalton, Pedro Bay, and Port Alsworth in 2005, to document subsistence uses and harvests and demographic and other economic data for the study year of 2004 (Fall et al. 2006). This report documents findings from phase II which expanded the study to 5 additional communities within the watersheds that...
This dataset provides field tagging and recapture information used to examine the movement patterns of Arkansas River Shiner Notropis girardi and Emerald Shiner Notropis atherinoides. Fish were tagged and recaptured from October 2018 to June 2020 over two field seasons. Tagged fish were collected using seine netting at seven locations in the first field season and four locations in the second field season. Once captured, all fish were anesthetized using buffered tricaine methanesulfonate before measuring and tagging. Over the first field season (2018-2019), all fish were tagged with two visible implant elastomer (VIE) tags. Arkansas River Shiner ≥ 50 mm total length were also tagged with a passive integrated transponder...
The dwarf wedgemussel (Alasmidonta heterodon) is a federally endangered freshwater mussel that once ranged from New Brunswick to North Carolina, but now only exists in isolated populations throughout its diminished range. This study aimed to understand links between fish abundance and dwarf wedgemussel abundance and occurrence in the Connecticut and Delaware watersheds. Specifically, my study objectives were to 1) characterize fish assemblages near dwarf wedgemussel locations and unoccupied locations, 2) determine if dwarf wedgemussel occurrence and abundance are related to abundance of the known host fish species, tessellated darter and other potential host fish species per St. John White et. al. (2017). Two fish...
