Here we explore the possibility that the landscape and the quality of the terrestrial habitat are unsuitable for these populations. Spawn of Rana arvalis and R. temporaria was introduced into ponds in a south Swedish agricultural landscape in 2003 (eight ponds) and 2004 (ten ponds). Metamorphs emerged from nine (R. a.) and 12 (R. t.) of these. In years following the introduction, spawn was found in five (R. a.) and eight (R. t.) of these 18 ponds. The number of spawn clumps peaked two years after the introduction. Three or four years after the introduction, breeding persisted in only two of the ponds (where both species were breeding). One year later also these populations had also become extinct. In control ponds (ponds within 750 m of the introduction ponds), spawn of R. temporaria was occasionally found but there was no trend, nor any temporal peak in frequency or quantity of spawn in these ponds. There were calling males of both species already one year after the introduction at a few ponds, indicating an unusually early maturation for some individuals. We suggest that the terrestrial habitat in this region is not suitable for the continued presence of populations of R. arvalis and R. temporaria. This may be related to the habitat per se or to the isolation of the populations.","PeriodicalId":55499,"journal":{"name":"Applied Herpetology","volume":"6 1","pages":"227-236"},"PeriodicalIF":0.0,"publicationDate":"2009-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1163/157075408X386196","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64922068","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}

Although many amphibian marking techniques have been developed, few meet the rigorous assumptions of capture-mark-recapture models. Also, excessive toe-clipping may affect frog survivorship adversely. We tested the efficacy of a new hybrid marking technique (VIE-C) that combines Visible Implant Elastomer (VIE) and toe-clipping on four species of treefrogs in West-Central Florida. Of the 840 treefrogs recaptured over a 15-month period, only one mark was unreadable. A significantly higher percentage of VIE marks (80%) than toe-clips (55%) remained viable for the duration of the study. On average, toe-clips remained readable for 100 days, and VIE marks remained readable for 112 days. There were no significant species differences in the length of time that either type of mark lasted. The hybrid VIE-C method represents an improvement over either method used alone, but the VIE mark will be more helpful in correctly reading and clarifying toe-clipping errors than will toe-clips be helpful in reading and clarifying VIE marks.","PeriodicalId":55499,"journal":{"name":"Applied Herpetology","volume":"6 1","pages":"247-256"},"PeriodicalIF":0.0,"publicationDate":"2009-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1163/157075409X420042","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64923149","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}

However, H. turcicus has spread to several New World countries including Cuba, Mexico, Puerto Rico, Panama, and the United States. The first verified report of H. turcicus in the United States is known from Key West, Florida in 1915, with other notable introductions documented in Arizona, California, Louisiana, Alabama, Texas, and other areas of Florida (Lever, 2003). Spread of this species has since been documented in many additional states (Livo et al., 1998; Hare, 2006; Kleopfer et al., 2006; Reed et al., 2006; NatureServe, 2008; Platt et al., 2008). Human-mediated dispersal is thought to be the major cause of this species’ dramatic range expansion (Lever, 2003), and Locey and Stone (2006) suggested that dispersal ability is limited and jump dispersal events are the major mode of expansion. Climate is thought to be a major factor preventing the northward spread of this species (Meshaka et al., 2006). However, cold climates are circumvented through exploitation of heated buildings, demonstrated by gecko presence in Colorado, South Dakota, and Maryland (Livo et al., 1998; NatureServe, 2008; Platt et al., 2008). Hemidactylus turcicus has been recorded throughout much of East and South Texas, but notable gaps exist in its distribution, such as the apparent absence from the panhandle with the exception of Lubbock County (Dixon, 2000; Jadin and Coleman, 2007). Approximately 28 counties in Central Texas lack a record","PeriodicalId":55499,"journal":{"name":"Applied Herpetology","volume":"6 1","pages":"196-198"},"PeriodicalIF":0.0,"publicationDate":"2009-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1163/157075408X394142","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64922423","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}

Previous research suggests that preferences for ARs may vary among species and between different designs. To test these ideas further, we examined the influence of thermal and structural characteristics on use of three types of ARs by the nocturnal common gecko (Hoplodactylus maculatus) and diurnal McCann's skink (Oligosoma maccanni), two lizards endemic to New Zealand. The field study confirmed that the three ARs (triple-layered Onduline, triple-layered iron, solid concrete) differed in retreat-site temperatures provided during each of three seasons (winter, spring and summer). In their top spaces, Onduline ARs were the warmest by day, coolest by night, and thus displayed the largest diel variations in temperature. In the laboratory, common geckos showed a significant preference for Onduline whether ARs were exposed to a radiant overhead heat source or not, whereas skinks did not display any preference among the three types of ARs regardless of heating. The three types of ARs provided field temperatures within the thermal preference range of both species (data obtained from the literature) but only for the top spaces of the ARs and only during summer. Onduline was the only AR to consistently provide the temperatures preferred by pregnant females. Although this study suggests that structural properties alone may be sufficient to explain the preference of geckos for triple-layered Onduline stacks, it does not eliminate the possibility that attractive thermal properties also contribute. Long-term studies are needed to test the effects of artificial refuge supplementation on reptiles, and on their predators and competitors.","PeriodicalId":55499,"journal":{"name":"Applied Herpetology","volume":"6 1","pages":"307-326"},"PeriodicalIF":0.0,"publicationDate":"2009-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1163/157075409X432931","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64923359","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}

Case studies are described for all instances of internal implantation, ingestion, and external attachment of transmitters for which data are available. Signal range did not differ dramatically between attachment methods, but did differ between transmitter models and habitats in which iguanas were tracked. Only transmitters with coiled antennas showed a dramatic reduction in signal range. Longevity of transmitter attachment varied greatly among attachment methods, and was greatest for implantation, least for ingestion, and intermediate for external methods. Internal placement of transmitters via ingestion or implantation was advantageous in having no external apparatus to snag on vegetation or rocks. However, ingestion yielded less than one week of data, and implantation required costly, potentially stressful surgery. External attachment methods, including suturing of transmitters, mounting with adhesive, and harnesses or collars with breakaway mechanisms, entailed low cost and low risk, but were less reliable for long-term attachment. Harnesses or belts that lacked breakaway mechanisms entailed higher risk, because iguanas may suffer injury or death if not monitored frequently and recaptured for removal of attachment devices. In many studies, iguanas successfully mated, nested, and appeared to behave normally with transmitters attached by various methods. However, further research is needed to determine how different attachment methods affect the health, behavior, and survivorship of iguanas, particularly in smaller species and juveniles, which are more susceptible to predation.","PeriodicalId":55499,"journal":{"name":"Applied Herpetology","volume":"6 1","pages":"151-170"},"PeriodicalIF":0.0,"publicationDate":"2009-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1163/157075408X386169","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64921981","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}
