This dataset provides supporting information for the species distribution data used in the associated manuscript. Collections of five non-native fish species were made by a number of institutions, and several capture techniques were used. This dataset also includes number of individuals of each species captured at each locality.

This Data Release contains data on fish species abundance for selected streams of the Potomac River basin in eastern North America. This dataset supports analysis of karst streams in the Chesapeake Bay headwaters region and was funded by USGS Chesapeake Bay studies.

This data release provides spatial data for species distribution models developed for 24 stream fishes native to the Pacific Northwest, USA and associated model evaluation metrics used to determine the best supported model. These models support a larger analysis for understanding native stream fish vulnerability in the region, specifically population viability analyses built to determine species extinction risk. The models were developed using the Maximum Entropy (MaxEnt) machine learning approach. This approach is best suited for the presence only occurrence data available for our analyses. The point occurrences representing presences in the models were previously collated for the Pacific Northwest Rarity and Climate Sensitivity Index (Moore et al., 2025). The environmental predictors used to develop the models were chosen based on a combination of biological relevance to the included species and being uncorrelated with other selected predictors. Models were predicted across two possible extents for each species, the extent of the species' IUCN range polygon if available or the extent of a convex hull of occurrence records used to build the model.

This USGS data release documents presence and absences of 419 fish species in the conterminous United States for 35,918 stream reaches of the National Hydrography Dataset Plus Version 2.1 (NHDPlusV2.1). Sample dates for this dataset span 1990-2019. Fish samples were aligned to the Integrated Taxonomic Information System (ITIS), where each species record was assigned a Taxonomic Serial Number (TSN). The dataset is structured with records representing a stream reach (i.e. comid), sample description (i.e. source, date) and a series of 419 columns representing species where each species column is named as the TSN. Data can be visualized on the NHDPlusV2.1 after a tabular join using the field 'comid' or can be projected and visualized as point data using the latitude and longitude fields (using coordinate reference system NAD83) that represent the midpoint of the stream reach that they were associated with. Data are provided in comma separated value (CSV) format.

This USGS data release documents species distribution models for 419 fluvial fish species in their native ranges of the conterminous United States. Source data, supporting code and model results are documented in this data package. Boosted Regression Tree (BRT) models were used to develop presence/absence predictions for each of the National Hydrography Dataset Plus Version 2.1 stream segments within a species' native range. The predictions provided can be linked to the NHDPlusV2.1 geospatial dataset through the Common identifier of an NHDFlowline feature (COMID) to create a spatial depiction of the models. A readme file and metadata (xml) provide further information on included data and processing steps.

This data release contains predictions of selected  fish community metrics and fish species occurrence using Random Forest models with landscape data for inland reaches across the Chesapeake Bay Watershed (CBW). Predictions were made at four time intervals (2001, 2006, 2011, and 2016) according to changes in landcover using the National Land Cover Database (NLCD). The fish sampling data used to compute these metrics were compiled from various fish sampling programs conducted by state and federal agencies, county governments, universities, and river basin commissions across the watershed. Community metrics describe composition, tolerances, habitat preferences, and functional traits of fish communities (and were derived from Krause and Maloney, 2021). Community analyses were developed for four aggregated Level III ecoregions: Northern Appalachians (NAP), Southern Appalachians [split into two sub-regions; the SAP-Piedmont (Piedmont and Northern Piedmont Ecoregions; SAPPIED] and other ecoregions [SAPNW]) and the Coastal Plains (CPL), and a final index was calculated for each ecoregion as the average of selected metric deciles with higher scores inferring less biologically altered (i.e., better) conditions. Species distribution models were created for key sensitive and gamefish species (including Brook Trout, Northern Hog Sucker, Smallmouth Bass, and Torrent Sucker) to predict species occurrence. Uncertainty was calculated for both approaches using model prediction intervals. For complete data descriptions and data interpretation see associated publication (Maloney et al., 2022; https://doi.org/10.1016/j.ecolind.2021.108488).

This USGS data release contains products that resulted from aquatic species distribution modeling in the United States on the National Hydrography Dataset Plus Version 2.1. Source data, supporting code and model results are documented in this data release. The file species_model_list.csv provides a list of most recent models for each combination of species, habitat, and region.

We provide a comprehensive review of the status of non-native fishes in the central Indian River Lagoon (from Cape Canaveral to Grant-Valkaria, east of I-95) through literature review and field surveys. Historical records exist for 17 taxa (15 species, one hybrid, one species complex). We found historical records for one additional species and collected one species in our field survey that had never been recorded in the region before (and which we eradicated). Thus, we evaluate 19 total taxa herein. Of these, we document range expansion of four salt-tolerant cichlid species, extirpation of six species that were previously recorded from the area and eradication of three species. There was no noticeable change in geographic range for one widespread species and the records for one species are doubtful and may be erroneous. Currently, there is not enough information to evaluate geographic range for four species although at least one of these is established. We provide information on how non-native fishes may interact with or exacerbate phytoplankton blooms and resulting trophic cascades.
