Scientific studies accounted for 272 individuals. More than 256 Ozark hellbenders were taken for the pet trade for suppliers in Michigan, New Jersey, and Japan by collectors from Nebraska and Alabama. During the first weekend of September 1980, 171 were collected illegally. Estimates indicate that approximately 50% of the females were removed from the most significant hellbender habitat in the NFWR (riffle 2-3) that weekend. Between 1969 and 1980, coordination with the Missouri Department of Conservation helped insure that C. a. bishopi, used for scientific research, were not removed from a 2.67 km (NFWR 1) research section. Population estimates from 1970 and 1978 studies indicate stability in the most densely populated habitat. In the 1970's, larger samples of individuals collected for research were not removed from a single site, but a few individuals were collected from multiple sites within a 10 km reach of the NFWR. During 1982-1984 more than 100 individuals were removed from the same section as in 1980 by commercial collectors. This evidence supports harvesting of C. a. bishopi, especially illegal harvesting, as a contributing factor in the decline of this population and documents that the decline had begun by 1980.","PeriodicalId":55499,"journal":{"name":"Applied Herpetology","volume":"4 1","pages":"207-216"},"PeriodicalIF":0.0,"publicationDate":"2007-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1163/157075407781268354","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64918434","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, four species of marine turtles are known from the region. Ecological relationships of an introduced frog ( E. johnstonei ) and an introduced lizard ( A. sagrei ) should be monitored in order to evaluate any potentially negative impact on endemic congeners. Two endangered endemic species ( P. shrevei and C. vincenti ) may benefit from sympatry with the endemic parrot, Amazona guildingii , the national bird of St. Vincent, with which they share high-quality upland forest habitat. Like other West Indian herpetofaunas, that on St. Vincent faces threats that include dramatic habitat alterations, introduced predators (mongooses, domestic cats) and competitors (e.g., A. sagrei ), changes in the prey base, and the potential introduction of the chytrid fungus. These threats can best be addressed by development and implementation of effective management programs based on ecological studies by local and foreign biologists.","PeriodicalId":55499,"journal":{"name":"Applied Herpetology","volume":"4 1","pages":"295-312"},"PeriodicalIF":0.0,"publicationDate":"2007-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1163/157075407782424539","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64919269","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Few direct comparative studies exist for aquatic sampling methods for amphibians. The objective of this study was to simultaneously employ seven aquatic sampling methods in 10 wetlands to compare amphibian species richness and number of individuals detected with each method. Four sampling methods allowed counts of individuals (metal dipnet, D-frame dipnet, box trap, crayfish trap), whereas the other three methods allowed detection of species (visual encounter, aural, and froglogger). Amphibian species richness was greatest with froglogger, box trap, and aural samples. For anuran species, the sampling methods by which each life stage was detected was related to relative length of larval and breeding periods and tadpole size. Detection probability of amphibians varied across sampling methods. Box trap sampling resulted in the most precise amphibian count, but the precision of all four count-based methods was low (coefficient of variation > 145 for all methods). The efficacy of the four count sampling methods at sampling fish and aquatic invertebrates was also analyzed because these predatory taxa are known to be important predictors of amphibian habitat distribution. Species richness and counts were similar for fish with the four methods, whereas invertebrate species richness and counts were greatest in box traps. An effective wetland amphibian monitoring program in the southeastern United States should include multiple sampling methods to obtain the most accurate assessment of species community composition at each site. The combined use of frogloggers, crayfish traps, and dipnets may be the most efficient and effective amphibian monitoring protocol.","PeriodicalId":55499,"journal":{"name":"Applied Herpetology","volume":"4 1","pages":"47-63"},"PeriodicalIF":0.0,"publicationDate":"2007-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1163/157075407779766750","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64917753","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fluctuating asymmetry (FA) is a potential measure of the developmental stress experienced by individuals in different environments, but few studies have linked FA with measures of individual quality in amphibians, which is an important assumption of FA. The spotted salamander, Ambystoma maculatum, has two rows of yellow spots on its dorsal surface which might represent useful characters in FA analyses and population monitoring, provided they truly reflect the quality of individuals. In this paper we compared left-right asymmetry in spot features (spot number, size and shape) and leg lengths of this species with traditional measures of body size and body condition among museum specimens to address this question. Of all three spot symmetry variables, the simplest (the difference in left-right spot numbers) was the most important. Individuals with asymmetrical spot numbers were also more asymmetrical in hind leg length, evidence that spots are supposed to be symmetrical in this species. Moreover, salamanders with symmetrical numbers of left-right dorsal spots had higher body condition scores than those with asymmetrical spot numbers. Combined, our results indicate that spot number symmetry provides a good index of individual quality. Further, as many proximate factors can influence body condition (such as recent foraging history), FA in characters such as spots or limbs may provide a more stable metric for assessing the developmental health or quality of individuals, which would prove valuable in amphibian conservation programs.","PeriodicalId":55499,"journal":{"name":"Applied Herpetology","volume":"48 1","pages":"195-205"},"PeriodicalIF":0.0,"publicationDate":"2007-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1163/157075407781268282","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64918081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
