    Kurt A. Buhlmann - A biological inventory of eight caves in northwestern Georgia with conservation implications. Journal of Cave and Karst Studies 63(3): 91-98. A BIOLOGICAL INVENTORY OF EIGHT CAVES IN NORTHWESTERN GEORGIA WITH CONSERVATION IMPLICATIONS KURT A. BUHLMANN1 University of Georgia, Savannah River Ecology Laboratory, Aiken, SC 29802 USA A 1995 biological inventory of 8 northwestern Georgia caves documented or re-confirmed the presence of 46 species of invertebrates, 35 considered troglobites or troglophiles. The study yielded new cave records for amphipods, isopods, diplurans, and carabid beetles. New state records for Georgia included a pselaphid beetle. Ten salamander species were in the 8 caves, including a true troglobite, the Tennessee cave salamander. Two frog, 4 bat, and 1 rodent species were also documented. One cave contained a large colony of gray bats. For carabid beetles, leiodid beetles, and millipeds, the species differed between the caves of Pigeon and Lookout Mountain. Diplurans were absent from Lookout Mountain caves, yet were present in all Pigeon Mountain caves. A comparison between 1967 and 1995 inventories of Pettijohns Cave noted the absence of 2 species of drip pool amphipods from the latter. One cave had been contaminated by a petroleum spill and the expected aquatic fauna was not found. Further inventory work is suggested and the results should be applied to management strategies that provide for both biodiver- sity protection and recreational cave use. Georgia is a cave-rich state, with most caves occurring in 29 July; Nash Waterfall Cave [NW] on 5 August; and Pigeon two distinct physiographic regions, the Cumberland Plateau Cave [PC] on 16 July (a) and 30 July (b).

Literature and documents were researched and reviewed as one component of this evaluation, although limited literature exists on this species. Recommendations resulting from this review are a result of the limited literature review, understanding ongoing conservation actions, input and suggestions from partners involved in conservation efforts, and the reviewers’ expertise on this species. Comments and suggestions regarding the five-year review were received from cave crayfish conservation partners listed in the peer review section of this document (Appendix A).

  • Field Sampling Techniques for Crayfish Eric R
    CHAPTER 8 Field Sampling Techniques for Crayfish Eric R. Larson1,* and Julian D. Olden2 Introduction Why do we study crayfi sh? Answers may range from their cultural or economic value (Jones et al. 2006) to ecological importance (Usio and Townsend 2004) to the high conservation need of many species (Taylor et al. 2007). Alternatively, one justifi cation for the emergence of crayfi sh as model organisms (e.g., Crandall 2000) has been their ubiquity and ease of collection relative to a rewarding range of biological insights. For example, Thomas Henry Huxley (1884) in his introduction to the study of zoology framed his book around crayfi sh in part because the “[the crayfi sh] is readily obtained.” Yet those of us who need to quantitatively sample crayfi sh recognize that “readily obtained” does not necessarily translate into representative of broader populations or communities. Huxley (1884) might be countered by observations like those of Rabeni et al. (1997), who note that no crayfi sh sampling method is without biases that may misrepresent attributes ranging from relative abundance to size and age structure of populations. Ultimately, quantitative sampling for crayfi sh presents a number of challenges to confound even the most experienced of fi eld biologists. Writing a comprehensive review of fi eld sampling methods for crayfi sh must accommodate both the diversity of crayfi sh themselves and the diversity of researchers interested in them. Crayfi sh occur in habitats ranging from large lakes to wadeable streams, to diffi cult to sample environments like caves and terrestrial burrows. These diff erent habitats demand diff erent sampling tools and approaches.

The crayfish genus Fallicambarus contains 19 species of primary burrowing freshwater cray- fish divided into two distinct subgenera. We test current hypotheses of the phylogenetic relationships among species within the genus as well as the monophyly of the genus. Our study samples all 19 species for five gene regions (both nuclear and mitochondrial) to esti- mate a robust phylogenetic hypothesis for the genus. We show that the genus is not a monophyletic group. The subgenus Creaserinus does fall out as a monophyletic group, but distinct from the subgenus Fallicambarus. The subgenus Fallicambarus appears to be mono- phyletic with the exception of the species Procambarus (Tenuicambarus) tenuis, which falls in the midst of this subgenus suggesting that it might be better classified as a Fallicambarus species. We also show that the species Fallicambarus fodiens is a species complex with dis- tinct evolutionary lineages that are regionalized to different geographic areas. Corresponding author: Keith A.
