Known localities in Central and South America include coastal sites in Nicaragua, Costa Rica, Panama, Colombia, Ecuador, Peru, and Brazil (Smith and Grant, 1961; Schauenberg, 1968; Mechler, 1968; Ineich, 1999; Lever, 2003; Kohler, 2003). This species was not previously known from Suriname (Hoogmoed, 1973), and this is the first reported population. The species was common on walls at night at the Eco Resort Hotel in Paramaribo, where no other nocturnal gecko species were seen, but was absent from less humanimpacted areas investigated in the Brokopondo District of Suriname. The nearest published localities are in Colombia. Kluge (1968 [1966]) reported the species from an unspecified locality in eastern Colombia. This record is not, however, supported by cited voucher material, making the southwestern Colombian localities of Guapi, Tumaco, Cali and Anchicaya (Ineich, 1999), each approximately 2750 km away, the nearest confirmed Lepidodactylus sites. The single Brazilian record is based on the holotype of Peropus neglectus Girard, 1858, a junior synonym of L. lugubris, from Rio de Janeiro, but the locality is suspect and the species has never again been found in Brazil (Vanzolini, 1968). Thus, the Paramaribo animals reported here represent the southernmost Atlantic population of Lepidodactylus lugubris and the only South American population east of the Isthmus of Panama.","PeriodicalId":55499,"journal":{"name":"Applied Herpetology","volume":"4 1","pages":"84-85"},"PeriodicalIF":0.0,"publicationDate":"2007-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1163/157075407779766660","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64917433","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 how animals use artificial retreats and which designs are most effective is therefore important. We tested the influence of retreat type, time-of-year and site on the use of artificial retreats by three species of terrestrial lizards (McCann's skink Oligosoma maccanni, common skink O. nigriplantare polychroma, and common gecko Hoplodactylus maculatus) in a remnant of grazed coastal shrubland at Birdlings Flat, New Zealand. Monthly capture sessions took place at two sites between December 2003 and November 2004. During 2160 retreat checks, 898 captures of 388 individual lizards were made. Geckos dominated the sample and displayed strong preferences for artificial retreats made of Onduline over corrugated iron and concrete tiles. Skinks used all types of artificial retreats without apparent preference. For all species, use of artificial retreats varied with time-of-year and was lowest in winter months. We also operated pitfall traps at these sites and made 329 captures of 205 individuals during 1920 trap-checks. Pitfall traps produced samples dominated by skinks. We conclude that Onduline retreats are a promising method for detecting terrestrial species of gecko in open habitats. Long-term studies are required to quantify the benefits of providing artificial retreats in restoration projects.","PeriodicalId":55499,"journal":{"name":"Applied Herpetology","volume":"4 1","pages":"227-243"},"PeriodicalIF":0.0,"publicationDate":"2007-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1163/157075407781268336","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64918647","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}

Females occupied a home range that averaged 1877 ± 1052 m2 (n = 4); male home ranges were similar, averaging 1740 ± 1288 m2 (n = 4; t-test = −0.12, P = 0.90). Cacao with a limited shade canopy was the predominant habitat available and used most frequently when compared to other habitats (χ2 = 116.67; P < 0.0001). Basiliscus plumifrons remained close to water although individuals occasionally traveled up to 80 m from water. However, both males (24.30 ± 1.93 m, n = 133) and females (26.82 ± 1.97 m, n = 128) maintained similar average distances from water resources (Kruskal-Wallis, H = 1.57, P = 0.20). Agroforestry systems connected to patches of riparian forest probably play an important role in the ecology and conservation of B. plumifrons.","PeriodicalId":55499,"journal":{"name":"Applied Herpetology","volume":"4 1","pages":"217-226"},"PeriodicalIF":0.0,"publicationDate":"2007-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1163/157075407781268327","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64918356","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, most studies have focused on the adults and none has been conducted to document the biology of the younger stages. In some instances, such as the Mona Island iguana (Cyclura cornuta stejnegeri), the biology of young stages has been overlooked due to their low relative abundance in the population. The causes of this population trait remain unknown and their extent from the conservation perspective is important because the scarcity of young stages has been considered a symptom of a declining population. We used radio telemetry to document life history of Mona Island iguana hatchlings during the first five months of life. Hatchlings dispersed following specific individual bearings from 102 m to 5080 m from the releases sites. Hatchlings settled down in diverse habitats used or not used by adult iguanas. Once settled, hatchlings spent most of the time (63%) in trees or perch locations above the ground. We report a conservative survival rate of 22% during the study period and Minimum Convex Polygon home ranges that vary from 0 m2 to 530 m2 (mean = 297). Our results suggest that the low relative abundance of the juvenile stages in the population is caused both by high predation rates during their dispersal phase, and hatchling microhabitat selection which precludes their detection in population surveys.","PeriodicalId":55499,"journal":{"name":"Applied Herpetology","volume":"4 1","pages":"365-376"},"PeriodicalIF":0.0,"publicationDate":"2007-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1163/157075407782424557","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64919294","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}

Over the centuries frogs have been a subject of fascination and entertainment, food, sources of medicinal preparations, and model organisms in biological research. For years many species were used in teaching anatomy, physiology and pharmacology, and in pregnancy testing. Current research has revealed antibiotic peptides, anti-tumour agents, analgesics and adhesive compounds in frog skin. There are also volatile compounds released from their skin; these chemicals repel various predators and may prove useful to humans. The global decline of amphibian populations is a major concern. Habitat destruction, global warming, and pandemic diseases are increasingly suspect in the decline of frog populations, but difficult to control. Restrictions in the food and pet trade are areas in which better enforcement could benefit anurans. However, not all human interactions have been deleterious to all species. The mechanics of highway building in North America commonly has created areas of run-off that provide breeding sites for select species. Similarly, in arid northern Australia, frogs aggregate in large numbers at artificial sites where human activity has provided stable water sources.","PeriodicalId":55499,"journal":{"name":"Applied Herpetology","volume":"4 1","pages":"1-18"},"PeriodicalIF":0.0,"publicationDate":"2007-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1163/157075407779766741","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64917621","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}

It has been suggested that stormwater ponds may also provide habitat for wildlife. However, wildlife attracted to ponds may be exposed to pollutants entering ponds in runoff. To assess the potential toxicity of nitrogen pollution of stormwater ponds to pond-breeding amphibians we monitored nitrogen levels in waters of eleven ponds in Baltimore County, Maryland. Levels of NH 3 , NO − 2 and NO − 3 exceeded lowest sublethal effects concentrations reported in the literature in <2% of the water samples collected, and when relatively high concentrations did occur they were restricted to only a portion of the pond. Water sampling during and following rain events also indicated little input of nitrogen to stormwater ponds through runoff. While the number of amphibians recorded at ponds varied from three to six species, there was no relationship between nitrogen levels and amphibian occurrence at ponds. Overall, nitrogen pollution of stormwater ponds in our study area appears to represent little or no direct risk to developing embryos and larvae of pond-breeding amphibians, although indirect effects and interaction of inorganic nitrogen with other pollutants warrant further investigation.","PeriodicalId":55499,"journal":{"name":"Applied Herpetology","volume":"4 1","pages":"19-29"},"PeriodicalIF":0.0,"publicationDate":"2007-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1163/157075407779766714","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64917725","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}
