High frequency of malformations in amphibians or of spondyloarthropathy in reptiles should stimulate evaluation for environmental causal factors. Notation of previously unrecognized/undescribed pathology affords unique opportunities.

Unfortunately, sampling terrapin populations is both time and labor intensive. We initiated studies to examine the efficacy of using head counts in tidal creeks as a rapid-assessment technique for monitoring terrapin populations. From 2005 to 2007, we conducted headcount surveys in conjunction with regular aquatic sampling. Head-count surveys consisted of recording the number of terrapins we observed from a boat going up (run 1) and down (run 2) tidal creeks. These surveys were conducted before aquatic sampling (i.e., low tide) as well as other times (e.g., high tide). We found the strongest positive relationship between the number of terrapins observed in run 1 combined with run 2 and the number of terrapins captured (R 2 = 0.538). We examined the effects of variables such as day of year, time of day, cloud cover, and creek location on the number of heads seen. Such models will allow effective monitoring of terrapin population trends and improve implementation of appropriate conservation measures. We recommend a refinement of head-count surveys and the involvement of citizen scientists to aid in the establishment of a range-wide monitoring program that will greatly increase survey effort while saving time and money. © Koninklijke Brill NV, Leiden, 2009","PeriodicalId":55499,"journal":{"name":"Applied Herpetology","volume":"6 1","pages":"237-245"},"PeriodicalIF":0.0,"publicationDate":"2009-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1163/157075408X397527","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64922410","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}

Management and conservation of the species has been hindered by the lack of population monitoring data. Recent studies have demonstrated that line transect distance sampling (LTDS) is efficient for estimating population parameters for gopher tortoises, yet this method has not gained wide-spread acceptance. We attempted to use LTDS to survey gopher tortoise populations on 20 protected areas across southern Georgia, USA in 2007 and 2008. We used a camera system to determine burrow occupancy at each site. The survey data were used to compare population estimates derived using LTDS (with burrow scoping) to estimates obtained with survey methods recommended in the 2007 Florida Gopher Tortoise Management Plan: area-constrained surveys of 15% of suitable habitat and a standard 50% burrow occupancy. LTDS estimates of tortoise population density ranged from 0.21 ± 0.04 tortoises/ha at Ohoopee Dunes Natural Area to 1.65 ± 0.37 tortoises/ha at General Coffee State Park. Distance sampling was generally very efficient (on average our survey rate was 0.88 km/h) and we obtained estimates of population size and density at 13 of the 20 sites. The method was much less efficient at sites with extremely low tortoise densities, and at sites where the survey area was poorly defined. Under the former circumstance, LTDS sampling would have required 88-1318 km of transect per site, which was beyond the scope of our overall project. In the latter circumstance additional ground-truthing of the habitat would have been necessary. Hence, we reported only the tortoise encounter rate and burrow occupancy estimates for these sites. Population estimates obtained with area-constrained surveys and a 50% burrow occupancy rate differed by as much as 114% from those obtained with LTDS and occupancy estimates based on burrow scoping.","PeriodicalId":55499,"journal":{"name":"Applied Herpetology","volume":"6 1","pages":"355-368"},"PeriodicalIF":0.0,"publicationDate":"2009-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1163/157075309X12470350858550","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64912900","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}

Understanding alligator populations in these systems is important because, although they are subject to the same management strategies and regulations as their more well-studied counterparts, they may have markedly different population dynamics and densities. Additionally, understanding patterns of alligator presence in isolated, seasonal wetlands is important to understanding how alligators may affect these critical habitats as ecosystem engineers. However, survey methods designed for large, open water systems may not work in these small, vegetated wetlands, and their efficacy in this habitat has yet to be documented. We conducted eyeshine surveys for alligators along walking transects through isolated, seasonal wetlands in southwest Georgia. We used a double-observer method with a Huggins closed capture analysis to determine the detection probability of this method, to model the effects of observer and wetland type on that parameter and to estimate abundance. We found that detection probability for eyeshine surveys under the best-supported model was 57%, between 2 and 5 times higher than documented in other habitats. We then compared eyeshine surveys with systematic trapping to ascertain which components of the population were more likely to be detected by each method. Both methods were effective in detecting a range of size classes in the wetlands; however, the two methods were most effective when used in concert. Wildlife biologists studying population trends and establishing harvest quotas can use this information to design surveys in the inland portion of the alligator’s range. © Koninklijke Brill NV, Leiden, 2009","PeriodicalId":55499,"journal":{"name":"Applied Herpetology","volume":"6 1","pages":"199-210"},"PeriodicalIF":0.0,"publicationDate":"2009-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1163/157075408X386132","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64921940","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}

Uncertainty about sampling techniques is particularly acute for approaches that involve multiple observers. I evaluated three techniques for sampling stream salamanders with multiple observers—time-constrained surveys, leaf-litter bags, and controlled-cobble added to the stream. I tested for differences among techniques, differences among habitats, and technique by habitat interactions. I also asked whether coefficients of variation across observers and sample dates differed among methods and habitats. For all species and life-stages, time-constrained surveys produced higher counts of stream salamanders and greater richness estimates than did leaf-litter bags or controlled-cobble surveys. However, interactions between techniques and habitat were never significant, indicating that all the methods detected similar patterns in counts among stream habitats. Coefficients of variation in single-species counts tended to be higher for time-constrained surveys, whereas CVs for species richness were significantly lower for time-constrained surveys. Overall, these results suggest that: (1) time-constrained surveys for stream salamanders work surprisingly well even with multiple observers, (2) leaf-litter bags may be quite useful for single-species studies, but are less effective for multi-species sampling, and (3) controlled-cobble added to streams is not particularly effective for sampling salamanders in rocky streams.","PeriodicalId":55499,"journal":{"name":"Applied Herpetology","volume":"6 1","pages":"211-226"},"PeriodicalIF":0.0,"publicationDate":"2009-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1163/157075408X386178","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64921992","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}
