The frog was found in or near an air container at the Qantas Cargo area. It is not known from which aircraft, cargo or country the frog originated. This species is not known to have been recorded in Australia, but it has been accidentally imported into New Zealand. A single live specimen was accidentally introduced in cargo containing a garden statue from Vietnam and intercepted at a wharf (Gill et al., 2001). Kaloula pulchra is distributed over a 2,283,959 km2 area from Nepal and north-eastern India through Myanmar and Thailand to southern China, Singapore, Sumatra, Borneo, and Sulawesi (Inger and Lian, 1996). It inhabits a wide range of habitats, including wetlands, riverbanks, forests and residential, agricultural and urban areas (IUCN et al., 2004). Kaloula pulchra meets many of the criteria for a vertebrate pest according to the contemporary Australian Risk Assessment model (see Bomford, 2003). Because of its close association with humans (Frost, 2004) it has already been introduced and established in Singapore, Borneo and Celebes (Inger, 1966; Lim and Lim, 1996; Iskandar, 1998). At present, the Cane Toad Bufo marinus is the only exotic amphibian known to have become established as a feral pest in Australia.

At least two other independent introductions of H. turcicus are believed to have occurred, one in New Orleans, Louisiana in the late 1940’s (Etheridge, 1952), and the other near the border of Mexico in Brownsville, Texas, in the early 1950’s (Conant, 1955). They have since been found in Alabama, Arizona, Arkansas, California, Georgia, Kansas, Maryland, Mississippi, Nevada, New Mexico, South Carolina, Utah, and Virginia (Hare, 2006; NatureServe, 2006; Reed et al., 2006). In the southern states, only North Carolina and Tennessee have no records. H. turcicus is nocturnal and in its introduced range associated with urban and suburban habitats, feeds on insects attracted to outdoor lights (Davis, 1974). Its success as a colonizer has been attributed to quick maturation, limited interspecific competition, low predation pressure, and multiple clutches per reproductive season (Selcer, 1986). In Texas, Davis (1974) showed that H. turcicus had expanded its range north, using highways as corridors to human domiciles, but remaining below a line from Del Rio through San Antonio to Austin and Houston. With few barriers and increasing transportation of this species to new localities, H. turcicus is becoming common throughout urban areas of the southern United States (Meshaka et al., 2006). In Texas it is currently documented in more than 70 counties (Dixon, 2000).

These include four species of marine turtles, two of which (Eretmochelys imbricata and Chelonia mydas) are known to nest on the nation's numerous sandy beaches and forage in nearshore waters. The low-lying and largely sedimentary islands of Antigua (280 km2) and Barbuda (161 km2) formed a single island as recently as 12,000 years ago and exhibit a similar herpetofauna with high endemicity. At least four terrestrial species are endemic to the Antigua and Barbuda bank: Alsophis antiguae, Ameiva griswoldi, Anolis wattsi, Sphaerodactylus elegantulus (a possible fifth being Barbuda's Anolis forresti, if not synonymous with A wattsi), and a further five are Lesser Antillean endemics. Only six species have been documented on the small, rugged volcanic island of Redonda (1 km2), but as many as half of them occur nowhere else (Ameiva atrata, Anolis nubilus, and a potentially new Sphaerodactylus sp.). Centuries of forest clearance, overgrazing and development, coupled with the introduction of small Asian mongooses (Herpestes javanicus), black rats (Rattus rattus) and other alien invasive species, has endangered many of the nation's wildlife, and at least four indigenous reptiles have been extirpated (Boa constrictor, Clelia clelia, Iguana delicatissima, and Leiocephalus cuneus). Recent moves to enlarge the nation's protected area network are encouraging, but need to be supported with stronger legislation and proper investment in management staff and resources. This paper presents conservation recommendations and describes two projects that have adopted innovative approaches to save the most critically endangered reptiles — the Jumby Bay Hawksbill Project and the Antiguan Racer Conservation Project.","PeriodicalId":55499,"journal":{"name":"Applied Herpetology","volume":"4 1","pages":"97-130"},"PeriodicalIF":0.0,"publicationDate":"2007-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1163/157075407780681338","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64917977","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}

Among terrestrial or freshwater species, two groups may be distinguished. The first group comprises 35 native species, of which seven are currently extinct or vanished. These species are often endemic to a bank and make up the initial herpetofauna of the French West Indies. Disregarding two species impossible to rule on due to lack of data, the second group includes twelve species that were introduced. Except for marine turtles and some terrestrial species for which the decline was due to human predation, the extinctions primarily involved ground living reptiles of average size and round section body shape. Habitat degradation and mammalian predator introductions have probably contributed to the extinction of these species, in addition to a possible direct impact of man. To better understand the threats to species, we suggest studying the interactions between native herpetofauna and introduced competitors or predators, taking into account the habitat structure. This would help to give the necessary information for successful management measures for conservation or restoration. As an example, the conservation of the Petite Terre (Guadeloupe) Iguana delicatissima population requires identifying both the mechanisms that regulate its population and their relationships to catastrophic climatic events.","PeriodicalId":55499,"journal":{"name":"Applied Herpetology","volume":"4 1","pages":"131-161"},"PeriodicalIF":0.0,"publicationDate":"2007-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1163/157075407780681356","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64918119","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 is divided in three physiographic regions or areas of relief: the mountainous interior, the karst region, and the coastal plains and valleys. The island comprises six ecological life zones: subtropical dry forest, subtropical moist forest, subtropical wet forest, subtropical rain forest, lower montane wet forest and lower montane rain forest. The herpetofauna of Puerto Rico consists of 25 species of amphibians (19 native, six introduced) and 56 species of reptiles (52 native, four introduced). The goal of this paper is to describe some of the present studies directed towards the conservation of Puerto Rican herpetofauna. Eleutherodactylus karlschmidti, E. jasperi and E. eneidae have not been seen or heard since 1976, 1981 and 1990, respectively, and are probably extinct. Since 2000, the potential causes of amphibian declines in Puerto Rico have been studied, and a synergistic interaction between climate change (increased dry periods) and disease (chytridiomycosis) have been proposed as an explanation for the patterns observed. Recovery efforts for Peltophryne lemur include a captive-breeding program, reintroductions island-wide educational outreach, protection and restoration of existing habitat, and the creation of new breeding ponds. Among reptiles, the first conservation efforts to protect Epicrates inornatus were limited to trying to halt collection and hunting. However, current strategies to preserve the boa include gathering basic biological information, habitat conservation, and educational outreach. Recent efforts for the conservation of Trachemys s. stejnegeri combine three research approaches to clarify the status of local populations: a mark-recapture-release study, field monitoring of reproductive activity (i. e., nocturnal patrolling to identify nesting activity), and field assessment of the potential impact of introduced species, particularly identification of predatory species and exotic turtles. Recovery initiatives for Cyclura stejnegeri include management of invasive mammals, a headstart program for hatchling iguanas, and the assessment of the etiology of a condition causing blindness in adult iguanas. A reforestation project aimed at recovering a local herpetofaunal assemblage after disturbances in a limestone valley in northern Puerto Rico is discussed. As population sizes of common colonizers such as Eleutherodactylus and Anolis increased, larger forest-interior and predatory species like Epicrates inornatus, Alsophis portoricensis and Anolis cuvieri followed. Finally, the Mona Island marine turtle monitoring program is discussed and compared to other similar programs in Puerto Rico. As these and other similar conservation efforts provide scientifically based management recommendations, we hope to succeed in conserving the diverse herpetofauna that characterizes Puerto Rico.","PeriodicalId":55499,"journal":{"name":"Applied Herpetology","volume":"4 1","pages":"327-345"},"PeriodicalIF":0.0,"publicationDate":"2007-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1163/157075407782424566","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64918910","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}

Of the two, LSJ is the more developed, with regular shipments of plants and building materials supporting the ongoing modifications. Two visits to LSJ, one in 2005 and one in 2006, revealed the presence of several new species on the island and allowed us to document reports of others. The Cuban treefrog has been spreading in the Caribbean in recent decades. It is now common in the USVI (Platenberg and Boulon, 2006) and nearby British Virgin Islands (BVI; Perry and Gerber, 2006). Remarkably, the USVI Division of Fish and Wildlife previously made the following suggestion about the species (Anonymous, 1991): “Cuban tree frogs [were] introduced to the Virgin Islands in the 1970s as hitch-hikers in potted plants. The only cure for the noise is to capture the frogs and release them in some uninhabited area.” This doubtlessly has exacerbated the spread of this damaging invasive.
