“…Gore and Bryant (1990) found that O. neglectus partition their habitats, with young typically found in moderate-velocity (25-45 cm/s) cobble habitats and adults in low-velocity (0 cm/s) macrophyte beds or high-velocity ([65 cm/s) cobbled habitats. However, other studies (Flinders and Magoulick 2005;Magoulick and DiStefano 2007) reported no significant difference in habitat selection by different size classes of O. neglectus or O. n. chaenodactylus (Williams 1952). The range of water depth, current velocities, and substrate in riffles measured in our study were comparable with previously reported values (Flinders and Magoulick 2005;Magoulick and DiStefano 2007;Rabalais and Magoulick 2006 [3), possibly explaining the lower densities of O. n. neglectus in Shoal Creek, which was significantly deeper than the other streams sampled in our study.…”

The inverse relation between crayfish density and stream size (C5 orders) or watershed size may be related to the proportional decrease in allochthonous materials in larger streams (Vannote et al 1980), loss of habitat heterogeneity (Clark 2009;Mitchell and Smock 1991), smaller percentage of suitable habitat (Burkey and Simon 2010;DiStefano et al 2008;Lodge and Hill 1994;Westhoff et al 2006), or increased predation (Flinders and Magoulick 2003;Hill and Lodge 1995;Stein and Magnuson 1976).…”

“…In situ testing of crayfish was an important tool for showing that the absence of crayfish populations below mining sites was the result of metal exposure as opposed to habitat loss due to physical impairment by mine waste (e.g., sedimentation by mine tailings). Although the diversity of crayfish in the Missouri Ozarks is high ([25 species;Pfleiger 1996), many taxa are restricted to a single drainage and are further restricted within drainages due to macrohabitat partitioning between species (DiStefano et al 2003;Flinders and Magoulick 2005;Rabeni 1985). O. macrus is endemic to the Ozark Highlands and is primarily found in the westward-flowing rivers north of the Illinois River in Oklahoma, including the Spring River.…”

“…Previous studies have found other crayfish species to either favor 378 or disfavor smaller and potentially intermittent streams due to different tolerances to abiotic 379 factors like stream drying and biotic factors like longitudinally structured predator communities 380 (Flinders & Magoulick, 2005;Creed, 2006). However, as an exception to our finding that pilose 381 crayfishes did not historically occur in the smallest streams, we did find some positive 382 association between these crayfishes and the absolute smallest streams in our region as measured 383 by flow accumulation.…”

Our study evaluates the distribution, habitat associations, and current conservation status of the pilose crayfishes Pacifastacus connectens and Pacifastacus gambelii, two littlestudied and data-deficient species endemic to the western United States. We first developed a species distribution model (SDM) for the pilose crayfishes based on their historical occurrence records using boosted regression trees and freshwater GIS data layers. We then sampled 163 sites in the summers of 2016 and 2017 within the distribution of these crayfishes, including 50 where these species were observed historically. We next compared our field results to modeled predictions of suitable habitat from the SDM. Our SDM predicted 73 sites (45%) we sampled as suitable for the pilose crayfishes, with a moderate AUC value of 0.824. The pilose crayfishes were generally predicted to occur in larger streams and rivers with less extreme upstream temperature and precipitation seasonality. We found the pilose crayfishes at only 20 (12%) of the 163 total sites we sampled, 14 (20%) of the 73 sites predicted as suitable for them by our SDM, and 12 (24%) of 50 historical sites that we sampled. We found the invasive virile crayfish Faxonius virilis at 22 sites total and 12 (24%) historical sites for the pilose crayfishes, and the "native invader" signal crayfish Pacifastacus leniusculus at 29 sites total and 6 (12%) historical locations. We subsequently used a single classification tree to identify factors associated with our high rate of false positives for contemporary pilose crayfish distributions relative to our SDM. This classification tree identified the presence of invasive crayfishes, impairment of the benthic community, and sampling method as some of the factors differentiating false positives relative to true positives for the pilose crayfishes. Our study identified the historical distribution and habitat associations for P. connectens and P. gambelii using an SDM and contrasted this prediction to results of contemporary field sampling. We found that the pilose crayfishes have seemingly experienced substantial range declines, attributable to apparent displacement by invasive crayfishes and 19 Abstract 20 Our study evaluates the distribution, habitat associations, and current conservation status of the 21 pilose crayfishes Pacifastacus connectens and Pacifastacus gambelii, two little-studied and data-22 deficient species endemic to the western United States.

“…Crayfish are keystone species in many stream ecosystems since they create and establish habitat use of other sympatric aquatic species. Crayfish are among the largest macroinvertebrates and limit access for other taxa to aquatic food web energy transfer [1][2][3][4]. Crayfish are ecosystem engineers that provide a vital role in the structure and function of stream ecosystems [5,6] by determining species distribution and placement within the stream benthic habitat [7,8].…”

We evaluated habitat models that determined relative abundance relationships among microhabitat, reach and watershed-scale factors important for predicting habitat selection. Thirty stream reaches in central Indiana were sampled to determine relationships between habitat associations and relative abundance, size, and age associations of the Northern Clearwater Crayfish, Orconectes propinquus. Females are significantly more abundant than males and the frequency of crayfish in gravel substrate was significantly higher than that of cobble substrate. The sizes of crayfish in cobble substrate were significantly larger than individuals found in gravel substrates, while females were significantly larger than males in gravel substrates. Watershed variables were not significantly related to crayfish abundance. The only reach scale variable that proved to be significant was boulder substrate. Microhabitat variables showed a significant increase between CPUE and cobble and gravel substrates. Habitat models provide valuable information on the conservation status and habitat parameters responsible for determining species preferences, life history strategies, and relative abundance.
