Abstract Dam construction threatens global aquatic biodiversity by fragmenting stream networks and altering flow regimes. The negative effects of dams are exacerbated increased drought periods associated water withdrawals, especially in semi‐arid regions. Stream fishes particularly threatened owing to their mobile nature requirement for multiple habitats complete life cycles. An understanding relationships with fragmentation regimes, as coarse‐scale (e.g. catchment) constraints on species...
Reports of alien crayfish invasions are increasingly common and often associated with well-documented ecological effects including native biodiversity declines. Because most regions in the U.S. Canada have not been surveyed to detect presence gauge threat status such invasions, management agencies lack information on magnitude problems their respective jurisdictions. Our objectives were catalog, confirm summarize suspected that reported one state recent years. Data also examined for...
Abstract Fish populations may be isolated via natural conditions in geographically separated ecoregions. Although reconnecting these is not a management goal, we need to understand how persist across landscapes develop meaningful conservation actions, particularly for species occupying sensitive karst ecosystems. Our study objective was determine the physicochemical factors related occurrence of four spring‐associated fishes. Arbuckle Uplift and Ozark Highlands ecoregions, USA. We used...
With anthropogenic changes altering the environment and subsequent decline of natural habitats, it can be challenging to predict essential habitats for elusive difficult study taxa. Primary burrowing crayfish are one such group due complexity in sampling their semi-terrestrial, subterranean habitat. Sampling burrows usually requires a labor-intensive, time-consuming excavation or trapping process. However, limited information on suggests that fine-scale habitat variation may drive choice....
Abstract Knowledge of crayfish species’ life history traits is vital to their conservation and management. Fecundity one trait that a likely indicator extinction risk potential invasiveness. Fecundity-related data are lacking for the imperiled St. Francis River (Faxonius quadruncus) declining in presence invasive woodland hylas). We sampled ovigerous females three populations each F. quadruncus hylas Missouri (USA) Ozarks streams during April 2014 compare fecundity egg size between two...
North America harbors a rich freshwater fauna, but many of its taxa are narrowly-distributed and threatened with future range reductions from invasive species, habitat alterations, water quality degradation. The importance conserving species is well documented, mechanisms responsible for their distributions often poorly understood. Developing approaches to better address these unique requirements critical providing adequate conservation. We demonstrate the value fine-scale sampling through...
Abstract Since 1995 Faxonius rusticus (Girard, 1852) has continued to expand its range in Illinois, USA and cause displacement of native crayfishes. We revisit five historic collection sites for F. made by C.A. Taylor M. Redmer compare densities with sympatric crayfish species document changes over the past 25 years. additionally compiled data from vouchered specimens update Illinois. Data density indicates that is still common displacing at four sites. been collected 137 new including...
