“…In agreement with past studies (Poulson 1963;Noltie and Wicks 2001), the Ozark cavefish still appears to be distributed within the confines of the Springfield Plateau physiographic province. Suitable habitat is specifically defined as the phreatic zones of karstified carbonate bedrocks of the Mississippian Period (the Boone, Keokuk, Burlington, and Pierson Formations), collectively termed the Springfield Plateau Aquifer (or Boone-St. Joe aquifer; Fig.…”

“…Renewed efforts during the 1990s in Missouri by MDC expanded the number of Missouri localities to 20 in the six county area-Barry, Greene, Jasper, Lawrence, Newton, and Stone (Pflieger 1997;Noltie and Wicks 2001). No new sites in Oklahoma were discovered during this period.…”

“…Documented occurrences of Ozark cavefish are conspicuously absent from McDonald Co., although it is presumed to be part of the historic range (Brown et al 1982). Noltie and Wicks (2001) reasoned that suitable habitat is lacking in this county because of its geologic setting; however, there are at least eight caves in McDonald Co. harboring stygobionts (including two sites for the Bristly Cave Crayfish, Cambarus setosus; Graening et al 2006a); hence, at least some of this county contains suitable habitat. Ozark cavefish are rumored to occur at numerous localities at the periphery of its range in the tri-state area: ArkansasBoone, Carroll, and Madison Cos.; and OklahomaCherokee and Sequoyah Cos.

“…The resulting study delineates a groundwater recharge zone in which a given cavefish population resides; this zone, or basin, describes the total habitat for that population. The network of conduits within this zone must, of course, be phreatic and large enough for a fish to enter (Noltie and Wicks 2001). The known recharge zones with viable Ozark cavefish populations should be federally designated as critical habit units.…”

Here we review the thirty year recovery effort and conservation status of the Ozark cavefish, Amblyopsis rosae. We summarized the historic and current range of the species, and report county range extensions for both A. rosae and its confamilial Typhlichthys subterraneus. Ozark cavefish survey data spanning almost a century were analyzed for temporal trends using the Mann-Kendall Test/Sen's Slope Estimator Method. Results were inconclusive because variance was high and the majority of data sets were not sufficiently large to detect a trend. However, the two largest populations (Cave Springs Cave and Logan Cave, Benton Co., Arkansas) have stabilizing or increasing survey counts. While the number of active cavefish sites has decreased over 50% since 1990, the number of surveyed individuals has not. Reasons for endangerment were reanalyzed since federal listing; the primary threat has shifted from overcollection to habitat degradation. We analyzed the progress of recovery task implementation, and we critically evaluated the basis of delisting criteria. Recovery Task 1, the hydrogeologic delineation of subterranean habitats, is almost complete. Recovery Task 2 prescribes protection and management for Recovery Caves, and important progress has been made. Recovery Task 3 involves the development and implementation of monitoring programs in Recovery Caves. Several important studies have been performed, and indicate that many cavefish populations are experiencing chronic, low-level exposure to a suite of anthropogenic contaminants. Delisting conditions are largely unattainable as currently worded. We suggest that recovery criteria be amended such that habitat protection goals are attainable, that the list of Recovery Caves can be periodically updated, and that the recovery Environ Biol Fish (2010) 87:55-88 population goal is increased and distributed between more sites.

Assessing and conserving groundwater biodiversity: synthesis and perspectives

et al. 2009

View full text Add to dashboard Cite

SUMMARY1. This paper is a synthesis of a special issue on groundwater biodiversity with a focus on obligate subterranean species, the stygobionts. The series of papers constitutes a great leap forward in assessing and understanding biodiversity patterns because of the use of large quantitative data sets obtained over a broad geographic scale. They also represent a conceptual shift, away from a purely taxonomic and phylogenetic focus to the analysis of whole groundwater assemblages. 2. The general patterns emerging for groundwater fauna are: very high levels of endemism, low local diversity relative to regional diversity, a limited number of lineages, occurrence of many relicts, and truncated food webs with very few predators. 3. b-Diversity is at least as important as a-diversity in determining total richness at different scales (aquifer, basin and region) and overall taxa richness increases across spatial scales. 4. Advances in understanding groundwater biodiversity patterns further include identification of several important factors related to geology and hydrology that determine the composition of European stygobiotic assemblages. 5. Important challenges for future research include improving sampling strategies, filling gaps in sampling coverage, intensifying research on theoretical and statistical models, and including functional and genetic diversity components in biodiversity assessments. 6. Strategies are proposed for protecting groundwater biodiversity and an argument is made to integrate biodiversity in groundwater management. Applying principles such as complementarity and flexibility for groundwater biodiversity conservation is a major step toward delineating a reserve network that maximise species representation at the European scale.

Aim Over 250 species of obligate terrestrial cave‐dwelling animals (troglobionts) are known from single caves in the eastern United States. We investigate their geographical distribution, especially in relation to other troglobionts. We relate these patterns to taxonomic group, opportunities for dispersal and geographical location. Location Caves of the United States east of the Mississippi River. Methods We associated over 3000 records of more than 450 troglobiotic species and subspecies with hexagons of 1000, 5000 and 10,000 km2 in size. We calculated Moran's I, black–white joins and cubic regression of endemics on non‐endemics at all three spatial scales. For 5000 km2 hexagons, we modelled the spatial autocorrelation of the residuals of the cubic regression of endemics on non‐endemics. Results Differences among orders in percentage single‐cave endemism were not significant, except for Pseudoscorpionida, which was higher (69%) than any other order. At all three scales, Moran's I and black–white joins were significant, indicating a clumped distribution of both single‐cave endemics and other troglobionts. Spatial patterns were similar at all three scales and Moran's I was highest at 5000 km2. The cubic fit of endemics to non‐endemics was consistently better, with less systematic error or residuals, than were linear or quadratic models. Residuals showed a significant geographical pattern with excess endemics in more southerly locations. Main conclusions There was both a non‐spatial and spatial component to the pattern of single‐cave endemism. The non‐spatial component was the association of high levels of single‐cave endemism with areas of high diversity of non‐endemics. It may be that both are high because of high secondary productivity. Spatially, single‐cave endemism is high in central rather than peripheral areas and in the southern part of the range. It is not higher in areas of more dissected limestone, which would reduce migration rates; if anything endemism is lower. Regional spatial effects are important, indicating that cave communities cannot be understood (or protected) in isolation.
