Cambarus polypilosus sp. nov. is a stream-dwelling crayfish endemic to tributaries in the Buffalo and lower Duck River drainage, reach of Tennessee Western Highland Rim West-Central Tennessee, U.S.A. The new species closely allied three members former subgenus Glareocola, but can be differentiated from each by combination characters, including body size, coloration, spination, setation, form I male gonopod morphology. Several meristic measurements ratios also differentiate C. friaufi, which...
Cambarus (Cambarus) appalachiensis is a stream-dwelling crayfish endemic to the greater New River basins of Virginia and West Virginia. The new species morphologically most similar sciotensis. can be differentiated from C. sciotensis by its more elongated chelae which possess single mesial row tubercles, reduced no tuberculation on dorsal-longitudinal ridge dactyl, lateral impression. has subrectangular with two rows margin tubercles chelae, as well both pronounced Several meristic ratios...
The amazing levels of freshwater biodiversity found in the Appalachian Mountains eastern United States are among highest recorded globally. Localized endemics make up much this diversity, with numerous fish, mussels, salamanders and crayfish often being restricted to a single watershed, some instances, subwatersheds. Much diversity is product processes vicariance historical stream drainage patterns. Herein, we describe three new species, all previously members Cambarus robustus complex,...
A new species of burrowing crayfish, Cambarus (Jugicambarus) adustus, is described from Lewis County in northeastern Kentucky, USA. The most similar morphologically to C. dubius. adustus coloration differs dubius by lacking red, orange and blue hues, instead brown over the entire body surface. Morphological differences between exist form I male gonopod, with possessing a caudal knob, while does not. In addition, lateral carapace distinctly tuberculate, whereas lacks extensive tuberculation....
The disjunct distribution of Cambarus monongalensis has led to speculation about its taxonomic status. An Appalachian Plateau population occurs in northern and central West Virginia Southwestern Pennsylvania, a mountain the Allegheny Mountains Ridge Valley physiographic provinces Virginias. Herein we describe as fetzneri sp. nov. two species differ genetically morphologically, have different color patterns. Specifically, C. chelae lack extensive red coloration on distal end propodus dactyl,...
Freshwater crayfish are amongst the largest macroinvertebrates and play a keystone role in ecosystems they occupy. Understanding global distribution of these animals is often hindered due to paucity distributional data. Additionally, non-native introductions becoming more frequent, which can cause severe environmental economic impacts. Management decisions related their habitats require accurate, up-to-date data mapping tools. Such currently patchily distributed with limited accessibility...
The Cataloochee Crayfish, Cambarus ectopistes sp. nov., is a large, stream-dwelling crayfish that occupies narrow noncontiguous distribution within the Appalachian Mountain region running through Upper Tennessee River basin, in French Broad, Pigeon, and Nolichucky watersheds along North Carolina border. It split from southernmost extent of C. robustus species complex, morphologically genetically most similar to second undescribed member group endemic upper watershed Carolina. nov. can be...
ABSTRACT Crayfish are keystone species and ecosystem engineers in aquatic ecosystems, many require conservation to support their continued persistence. Unfortunately, managers often lack basic data needed make effective decisions. This of is especially true within the New River catchment, United States, where there 12 known crayfish species, but it unclear which those native scant ecological life history available for species. Therefore, our objective was investigate coarse‐scale occurrence...
The ecology of primary burrowing crayfishes is poorly understood, especially for high-elevation species. An ecological study Cambarus (Jugicambarus) dubius (Upland Burrowing Crayfish) was conducted at Terra Alta, Preston County, WV (elevation 781 m). sought life-history information including size sexual maturity, age cohort designation, and estimation. density distribution burrow portals C. were examined within near seeps in forested disturbed habitats. Data also collected on intraspecific...
The diversity of crayfishes in West Virginia represents a transition between the species-rich southern Appalachian faunas and depauperate crayfish northeastern United States. Currently, 22 described species occur state, which 6 are given S1 status, 3 introduced species. One species, Orconectes limosus (Spinycheek Crayfish) is considered extirpated within past decade. Imperiled include Cambarus veteranus (Big Sandy Crayfish), elkensis (Elk River longulus (Atlantic Slope nerterius (Greenbrier...
Among crayfish, primary burrowing species are the least understood ecologically. Many crayfish inhabit floodplains where forested landscapes have been fragmented by agricultural, industrial, or residential uses. In this study, site occupancy rates |$(\psi)$| were modeled for two Fallicambarus fodiens (Cottle, 1863) and Cambarus thomai Jezerinac, 1993, from Ohio Kanawha river in West Virginia, U.S.A. is one of Virginia's rarest while C. prevalent most wetlands along both floodplains....
The crayfish fauna of West Virginia consists 23 species and several undescribed taxa. Most survey efforts documenting this have been conducted in lotic waterways throughout the Appalachian plateau, Allegheny Mountains, Ridge Valley physiographic provinces. Bottomland forests, swamps, marshes associated with large river floodplain such as Ohio River historically under-surveyed state. These habitats harbor richest primary burrowing Virginia, are worthy efforts. In an effort to fill void,...
West Virginia's crayfishes have received moderate attention since publication of Jezerinac et al.'s (1995) monograph the state fauna. Survey efforts were initiated over summers 2006 and 2007 to gather voucher material for Indiana Biological Survey's Crustacean Collection. These collections provided new information regarding distribution, natural history, life taxonomy, conservation status Cambarus (Cambarus) carinirostris, C. (C.) bartonii cavatus, sciotensis, (Hiaticambarus) chasmodactylus,...
We used radio telemetry to track the daily movements of Cambarus chasmodactylus (New River Crayfish) in Anthony Creek, West Virginia, help us better understand activity and habitat preferences cambarid crayfish. fitted ten 0.8-g transmitters chelae C. (6 form I males/3 II males/1 female) released them at their initial point capture. tracked animals for 5 consecutive days, after which we initiated a 20-d noninteraction period followed by 6 more days tracking. After locating an individual,...
Cambarus (Puncticambarus) callainus, new species, is a stream-dwelling crayfish endemic to the Big Sandy River basin in Kentucky, Virginia, and West Virginia. Within basin, C. callainus occurs Levisa, Tug, Russell fork watersheds. The species morphologically genetically most similar veteranus, which Upper Guyandotte of can be differentiated from veteranus by its more lanceolate rostrum (width less than 50% length), slightly obtuse suborbital angle, well-defined lateral impression at base chelae.
Conservation concerns for imperiled crayfish faunas have recently increased among resource management agencies. In Maryland, major include the introduction of nonnative crayfishes and their impacts on native species. This study documented species distribution conservation standing western Maryland. Native Orconectes (Crockerinus) obscurus (Allegheny Crayfish), Cambarus (Jugicambarus) dubius (Upland Burrowing (Cambarus) bartonii (Common carinirostris (Rock Crawfish). Introduced are...

Cambarus (Jugicambarus) dubius Faxon, 1884 is a polychromatic montane burrowing crayfish with long, turbulent taxonomic history since its original description by Walter Faxon in 1884. Over the years, many distinct color phases have been identified, majority of these being confined to specific geographic or physiographic region central and southern Appalachians. Previous investigations this species (e.g., Dewees 1972) were unable discover consistent morphological differences among various...
Abstract Animal weapons are diverse and often exaggerated structures associated with sexual selection male–male combat. Despite their diversity, our knowledge of these comes primarily from studies that focus on the size neglect other components, such as shape or performance. Furthermore, can exhibit species-level plasticity based nutrition ecological variables, but few have documented seasonal variation in weapon plasticity. Here, we investigate how size, performance differ across adult male...
