The success of using artificial retreats for monitoring is dependent on our ability to maximise detection and minimise variability in sightings within a sampling period. Because ectotherms use retreats for their thermal properties, it may be possible to identify weather conditions during which animals consistently use retreats and design a monitoring protocol based on optimal conditions. We investigated the use of artificial retreats by common skinks, Oligosoma polychroma, in mixed grassland habitat in southern New Zealand under various weather conditions and at a range of times of day. We recorded 1175 sightings of skinks during 1800 artificial retreat checks over a nine day period in early summer 2008. Ambient temperature, rainfall, humidity and time of day were the strongest predictors of skink sightings beneath retreats. Skink sightings were highest and least variable: (1) in an ambient temperature range of 12-18°C, (2) during light or no rain, and (3) at low levels of relative humidity. Under optimal weather conditions, skink counts were similar during the day (8 a.m. to 5 p.m. inclusive) but lower during the evening (8 p.m.). Observer variability, type of substrate beneath the retreat and retreat colour did not significantly influence the number of skinks sighted. We highlight the need to optimise protocols for checking artificial retreats on a species- and site-specific basis before attempting to evaluate their use as a monitoring tool for herpetofauna.","PeriodicalId":55499,"journal":{"name":"Applied Herpetology","volume":"48 1","pages":"379-390"},"PeriodicalIF":0.0,"publicationDate":"2009-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1163/157075309X12531848432985","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64912687","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}

While pursuing these situations, it is important that evidence is collected in an organized and systematic way to ensure successful prosecution or to mount a defense. There are different types of evidence that can be amassed to diagnose a disease/condition in a reptile case. Antemortem clinical investigations can be conducted for those cases where the animals are alive, while postmortem examinations should be pursued for animals that have expired. The purpose of this article is to review the common antemortem clinical techniques that can be used for forensic cases. There are a number of clinical diagnostics available for the forensic case, including the physical examination, clinical pathology, parasite diagnostics, infectious disease diagnostics, clinical toxicology, and diagnostic imaging. In addition to the clinical techniques, it is important to review and document the methods used to house and care for the animals. For this, a thorough review of the husbandry practices provided for the animal is needed.","PeriodicalId":55499,"journal":{"name":"Applied Herpetology","volume":"24 1","pages":"3-28"},"PeriodicalIF":0.0,"publicationDate":"2009-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1163/157075408X386141","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64921967","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}

Renccting the recent \"Glohal Amphibian Assessment\", 32 of 37 (86%) on· live species of amphibians are included on the IUeN Red List. Reptilian species given formal recognition as being in need of protection include the sea turtles (listed in CITES appendices and the IUCN Red List), the two native species of pond turtles (Traehelll)'s spp.: mCN, although one as being at \"lower risk\" ofextinc~ tion), both species of rock iguanas (Cyclfll\"ll spp.; CITES and IUCN), two giant galJiwasps (CeleslIu spp., meN), three boids (Epierates spp., CITES), a ground boa (Tropidophis haetiamls, CITES), and the Amer ican crocodile (Crocodyills aelltlls; CITES and IUCN). However, at least some additional squamate species appear to meet criteria for inclusion on the IUeN Red List. Four factors largely responsible for the status of these species arc: (I) small ranges, habitat specialization. and encroachment by human activities (many amphibians); (2) large size and cconomic value (turtles. iguanas, crocodile): (3) persecution by people who fear them (galliwasps and snakes); and (4) diurnally active, terrestrial. and vulnerable to predation by mon gooses and other introduced mammalian predators (some snakes, Mabllya). Although protection for a few species and for national parks in critical habitats is legislated, enforcement is sporadic and threats, mostly associated with exploitation and development, remain.

In the Pacific Northwest, timber harvest is known to increase peak stream temperatures to 24 ◦ C or higher, which has potential to negatively impact cold-water stream amphibians. I determined the Critical Thermal Maxima (CTmax) for two salamanders that are endemic to the Pacific Northwest. Rhyacotriton variegatus larvae acclimated at 10 ◦ C had mean CTmax of 26.7 ± 0. 7S D ◦ C and adults acclimated at 11 ◦ C had mean CTmax of 27.9 ± 1.1 ◦ C. These were among the lowest known values for any amphibian. Values were significantly higher for larval Dicamptodon tenebrosus acclimated at 14 ◦ C ( ¯ x = 29.1 ± 0.2 ◦ C). Although the smallest R. variegatus had some of the lowest values, size of larvae and adults did not influence CTmax in this species. Current forest practices retain riparian buffers along larger fish-bearing streams; however, such buffers along smaller headwaters and non-fish bearing streams may provide favorable habitat conditions for coldwater-associated species in the Pacific Northwest. The current study lends further evidence to the need for protection of Northwest stream amphibians from environmental perturbations. Forest guidelines that include riparian buffer zones and configurations of upland stands should be developed, while monitoring amphibian responses to determine their success.","PeriodicalId":55499,"journal":{"name":"Applied Herpetology","volume":"5 1","pages":"63-74"},"PeriodicalIF":0.0,"publicationDate":"2008-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1163/157075408783489211","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64919954","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}

Our marking strategy entailed injecting elastomer into the plantar surface of the digits and clipping only one toe. This method allows large numbers of frogs to be individually marked, reduces the potential for negative effects due to clipping multiple toes, and minimizes the frequency of elastomer migration from the injection site, a common problem with VIE marks on the body or limbs. We found retention rate of VIE marks in the digits to be similar to that of toe-clips, indicating that VIE provides a satisfactory alternative to multiple toe-clips. In addition, cost of materials, frog handling time, and ill effects were minimal. This VIE-C marking scheme is highly recommended when considering techniques for marking anurans, as it reduces potential negative effects of clipping multiple toes, and provides a large number of inexpensive and long-lasting individual marks that can be easily applied and quickly read in the field by trained observers.","PeriodicalId":55499,"journal":{"name":"Applied Herpetology","volume":"55 1","pages":"265-280"},"PeriodicalIF":0.0,"publicationDate":"2008-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1163/157075408785911002","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64920914","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}

We assessed the success of this type of translocation by monitoring the movements, spatial positioning, health, and reproductive activity of translocated and resident individuals at a site in central Florida from 2001 to 2004. By several criteria, the translocation was a success. Most translocated individuals remained on-site for at least one year, home ranges of resident individuals were not significantly different before and after translocation, home ranges of translocated individuals fit within the range of estimates reported in the literature, and neither body condition nor reproduction of either group of individuals could be shown to be affected by the translocation. On the other hand, several resident individuals altered their habitat use after translocation and the spatial positioning of resident individuals was different than that of individuals throughout; so, some potential exists for future off-site movements. The study illustrates two practical problems in assessing translocation success: lack of adequate pre-translocation data for both resident and translocated individuals, which interferes with documentation of translocation effects, and the necessarily small sample sizes, which reduces statistical power.","PeriodicalId":55499,"journal":{"name":"Applied Herpetology","volume":"20 1","pages":"145-160"},"PeriodicalIF":0.0,"publicationDate":"2008-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1163/157075408784648844","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64921088","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}
