The impacts of climate change on cold water species will likely manifest in populations at the trailing edge of their distribution. Rio Grande cutthroat trout (Oncorhynchus clarkii virginalis, RGCT) occupy arid southwestern U.S.A. streams at the southern-most edge of all cutthroat trout distributions; thus making RGCT particularly vulnerable to the anticipated warming and drying in this region. However, RGCT may possess a portfolio of life-history traits that aide in their persistence, attributes commonly observed in trailing edge populations. We marked RGCT across eight populations in 2016 and 2017 and used this capture-mark-recapture data to determine how environmental constraints influenced life-history trait...

However, RGCT may possess a portfolio of life-history traits that aide in their persistence, attributes commonly observed in trailing edge populations. We used stream discharge (flow) data collected along a temperature and stream drying gradient to determine how these environmental constraints influence life-history trait...
The impacts of climate change on cold water species will likely manifest in populations at the trailing edge of their distribution. Rio Grande cutthroat trout (Oncorhynchus clarkii virginalis, RGCT) occupy arid southwestern U.S.A. streams at the southern-most edge of all cutthroat trout distributions; thus making RGCT particularly vulnerable to the anticipated warming and drying in this region. We collected stream temperature and stream drying to determine how these environmental constraints influence life-history trait expression (length- and age-at-maturity), demography, and extirpation risk in RGCT populations from northern New Mexico, U.S.A. We found the rate at which RGCT reached maturity was highest at warm...

The dataset represents benthic aquatic macoinvertebrates collected from eight streams to characterize production in Rio Grande cutthroat trout (Oncorhynchus clarkii virginalis; RGCT) populations throughout northern New Mexico from 2016 through to 2017. The macroinvertebrates were sampled using Hess samplers with a 250 micron mesh and all taxa were identified to the lowest level of taxonomic resolution.
