Assessing short- and long-term anthropogenic threats to a reintroduced fish in a restored urban riverscape

Understanding which species can persist in human-modified environments is essential to biodiversity conservation in the Anthropocene. In urbanized environments, many stressors limit the persistence of imperiled native species via impacts on the abiotic and biotic environment. Habitat restoration followed by reintroduction of native species may be an effective strategy to maintain or even regenerate biodiversity in urbanized environments, but few studies have assessed these two conservation strategies concomitantly in urban freshwater ecosystems. We assessed short-term population dynamics and habitat associations of an endemic species of conservation concern, Guadalupe bass (Micropterus treculii, ‘GB’), that was reintroduced in a restored urbanized riverscape already occupied by a generalist congener, largemouth bass (M. salmoides, ‘LMB’). We performed four seasonal surveys of habitat association and one capture-mark-recapture survey of the two species at eight sites distribute..., , , # Data from: Assessing short- and long-term anthropogenic threats to a reintroduced fish in a restored urban riverscape

## Description of the data and file structure

Three data tables are provided in .csv format:
- **capture_mark_recapture** (.csv file): Input for Schnabel and Schumacher-Eschmeyer population size analysis.
- **habitat_association_fish** (.csv file): Input for outlying mean index (OMI) analysis.
- **habitat_association_transects** (.csv file): Input for outlying mean index (OMI) analysis.
