Anolis aeneus and A. trinitatis were introduced to Trinidad before 1900, and A. extremus was a more recent introduction in the 1960s-1980s. The three species are of similar body size, and A. aeneus and A. trinitatis are known to hybridize in Trinidad. Detailed studies from the late 1960s indicated that A. aeneus was widespread but A. trinitatis was localized and apparently in decline due to hybridization pressure. In this study we examined all the known sites of A. trinitatis (and A. extremus ) in Trinidad, and many new sites. A. trinitatis remained abundant in and to the east of San Fernando in southern Trinidad. Two small populations remained in northern Trinidad, at one site in Port of Spain and at St Augustine, but A. trinitatis no longer occurred at most former sites there. A. trinitatis and A. aeneus had high niche overlap (0.99 or greater) for the three dimensions examined (substrate type and perch height and diameter). Both species were apparently still spreading into vacant habitats east of San Fernando. Of 12 sites from which A. trinitatis had disappeared, four had no anoles, four had sparse populations of A. aeneus , and only four had dense populations of A. aeneus . This pattern suggests that the decline of A. trinitatis is not related to hybridization with or competition from A. aeneus . An alternative hypothesis is presented, that A. trinitatis requires more vegetated habitats, which have been increasingly lost during urban development especially in northern Trinidad. A. extremus is apparently now extinct in Trinidad.

Cuban treefrogs are native to Cuba, the Cayman Islands, and the Bahamas, but are increasingly recorded from other locations (Lever, 2003). The species was first collected in the British Virgin Islands (BVI) in 1990 (Owen et al., 2005) and has since spread, with about one new island record per year in the BVI (Owen et al., 2005, 2006; Perry and Gerber, 2006) and new localities in the United States Virgin Islands (Waddle et al., 2005; Platenberg and Boulon, 2006; Perry and Platenberg, 2007). Perry and Gerber (2006) mentioned that the species had been sighted on Guana Island, BVI, but did not provide any information that would allow the significance or circumstances of the event to be evaluated. Those details are provided herein. At about 2000 h on 21 October 2005, I collected an adult male (SVL = 72 mm) with small nuptial pads, foraging at a night light within the hotel complex on Guana Island. Guana Island is a private wildlife preserve. In the 12 months prior to the reported event, the small hotel on the island had imported relatively large quantities of construction materials and ornamental plants. However, hotel staff had made extensive attempts to prevent the arrival of the Cuban treefrog and other invasive species. These include manual searches of all arriving plants and other materials while still on the barges bringing them to the island, and on-island fumigation within an enclosure into which arriving materials and engine exhaust were introduced (Perry et al., 2006). No additional Cuban treefrogs have been seen on Guana since removal of that individual, despite extensive searches in 2006 and 2007.

古巴树蛙原产于古巴、开曼群岛和巴哈马群岛，但越来越多的记录来自其他地方(Lever, 2003)。该物种于1990年首次在英属维尔京群岛(BVI)被收集(Owen et al.， 2005)，此后开始扩散，在英属维尔京群岛每年约有一个新的岛屿记录(Owen et al.， 2005, 2006;Perry和Gerber, 2006)以及美属维尔京群岛的新地区(Waddle等人，2005;Platenberg and Boulon, 2006;Perry和Platenberg, 2007)。Perry和Gerber(2006)提到该物种曾在英属维尔京群岛瓜纳岛被发现，但没有提供任何信息来评估该事件的重要性或环境。这些细节在此提供。2005年10月21日约2000时，我在瓜纳岛酒店群的夜间灯光下采集了一只成年雄性(SVL = 72毫米)和小婚垫。瓜纳岛是一个私人野生动物保护区。在报告事件发生前的12个月里，岛上的小酒店进口了大量的建筑材料和观赏植物。然而，旅馆工作人员曾多次试图阻止古巴树蛙和其他入侵物种的到来。这些措施包括在将所有到达的植物和其他材料运至岛屿的驳船上进行人工搜索，以及在将到达的材料和发动机废气引入的围栏内进行岛上熏蒸(Perry et al.， 2006)。尽管在2006年和2007年进行了广泛的搜查，但自从那只古巴树蛙被移走后，在瓜纳没有看到更多的古巴树蛙。瓜纳岛提供RA P.1 (1-2) APHE:m v 1.24 Prn:7/01/2009;[14:03] [au:] [au:

I present an up-to-date annotated list of the herpetofauna of Martinique, and try to explain the causes responsible for the eradication of species such as Leptodactylus fallax , Boa sp. and Leiocephalus herminieri . Mabuya mabouya and Liophis cursor have not been seen for decades and may have been extirpated. It cannot be established that the mongoose was responsible; Didelphis marsupialis , of recent introduction, may have played an important role. Introduced and invasive species are numerous in Martinique: Chaunus marinus , Scinax ruber , Eleutherodactylus johnstonei , Gymnophthalmus underwoodi , Iguana iguana , Gekko gecko , Hemidactylus mabouia , without considering escaped pets and the dubious case of Allobates chalcopis as an endemic species. I also present the restoration plan for Iguana delicatissima in the French West Indies and the conservation work for this species in Martinique; increase of nesting areas, translocation, creation of numerous protected areas, and control of I. iguana . Of a total of 13 endemic and indigenous species from Martinique, three are definitely and a further two are probably eradicated. Including Guadeloupe, the French West Indies have the highest loss of herpetological biodiversity among all the islands in the West Indies.

In June 2008, we conducted a survey of Dominican herpetofaunal communities in habitats variously disturbed by human activity. Our rapid assessment found the highest abundance and species richness in moderately to substantially modified areas. We found relatively few species and low numbers of individuals in relatively natural high-elevation sites, dramatically altered urban areas, and active agricultural fields. In habitats subjected to intermediate levels of disturbance, such as a residential area and an inactive agricultural site invaded by dense exotic vegetation, complex physical habitat structure appeared to support the greatest herpetofaunal diversity. These results suggest that conservation efforts in the West Indies need not be restricted to pristine habitats, but also might include protection of slightly to moderately disturbed areas that may sustain greater biodiversity.

Measures of fluctuating asymmetry (FA) have been used to assess the significance of stress in amphibian populations. When animals with bilateral body plans are challenged by environmental stressors, departures from bilateral symmetry can emerge during development. The tendency for FA to develop has been linked to greater susceptibility to pathogens in many organisms. In our study, newts (Notophthalmus viridescens) infected with Ichthyophonus-sp. exhibited greater size-corrected FA of the hind limbs than uninfected animals from the same population. Among infected animals, however, the intensity of infection and the extent of hind limb asymmetry were not correlated, suggesting that asymmetry did not arise following infection, but rather that newts having greater FA may have been more susceptible to infection as a result of the same stresses that produced the increase in FA. There was no relationship between dorsal spot pattern FA and infection status or hind limb FA. We suggest that spot pattern may be less canalized than hind limb development. Newts are widely distributed and important components of freshwater communities in eastern North America and, thus, any change in their vitality may affect the composition of those communities. Analyses of hind limb FA may be a useful and non-invasive tool for identifying potentially vulnerable amphibian
