Allozyme-based genetic distances were used to determine the distinctness of six species of cave crayfish from the Ozark Plateau in Missouri, Arkanasa, and Oklahoma. One of the cave species is in the subgenus Erebicambarus and the others are in Jugica

Breeding site fidelity has evolved in many vertebrate taxa, suggesting both that site selection has an important influence on fitness potential and that the decision to reuse a nesting site is related to the individual’s prior nesting success at th

Understanding how populations are genetically and demographically connected is beneficial for species management, since gene flow and dispersal contribute to genetic diversity and population persistence. For hellbenders (Cryptobranchus alleganiensis)

Passive integrated transponder (PIT) tags are used in fisheries evaluations as a means of marking individual fish because they often have high retention rates, can be passively detected, do not affect fish behavior, and typically do not increase the

The hellbender (Cryptobranchus alleganiensis) is an obligately aquatic salamander that is in decline due to habitat loss and disease. Two subspecies of hellbender have been described based on morphological characteristics: C. a. alleganiensis (easter

Few studies have evaluated stocking programs for walleye Sander vitreus in the southern United States; this may be the first such study for a southern river. The Eleven Point River, located in southeastern Missouri and northeastern Arkansas, has been

Current understanding of the stress response in fishes has largely come from studies of freshwater-adapted salmonids, with proportionately few comparative studies having examined marine fishes. The current study sought to quantify the magnitude of ph

Bonefish, Albula spp., are popular sportfish that inhabit shallow nearshore environments in tropical and subtropical seas. Although catch and release is a common voluntary practice for anglers seeking bonefish, the post-release fate of bonefish is po

The range of the endangered Hell Creek Cave crayfish (Cambarus zophonastes) is expanded to include a second population, determined by genetic analyses. This crayfish is still restricted to Stone County, Arkansas, and is known from only 14 individuals
