“…The wide distribution of the species has been taken to be a testament of its dispersal abilities (Powell 2006). In combination with particular life-history traits related to its reproductive mode (direct developer, continuous reproduction ;Ovaska 1991;Bourne 1997;Ortega et al 2005) this has previously been seen as proof of its colonization potential. As a direct consequence, large-scale distribution models aimed at modeling potential range expansions based on present distribution patterns have recently been developed (Rödder 2009).…”

“…throughout different habitats (Schwartz and Henderson, 1991;Breuil, 2002). This trend was also confirmed by two studies on Erythrolamprus cursors' diet (Henderson 2004), finding both prey types and a small percentage of insects in their stomachs (Henderson and Bourgeois, 1993) in both E. cursor and E. juliae, which is not surprising considering local abundance of frogs and lizards (Ovaska, 1991;Roughgarden, 1995 , and the Turnip-Tailed Gecko (Thecadactylus rapicauda). Moreover, the Black Rat (R. rattus) and the House Mouse (Mus musculus domesticus) were probably introduced during the Napoleonic Wars (Breuil, 2009).…”

The Lesser Antilles is a biodiversity hot spot but unfortunately human disturbance has taken its toll, causing dramatic population declines and even extinction of numerous endemic species. Nevertheless, today the rediscovery of previously thought extinct species is not uncommon. Often, old museum specimens and their original descriptions are the only information available for such species. The application of molecular phylogenetic relationships to extant species can help to elucidate pivotal information on their ecology and conservation. Erythrolamprus cursor is possibly an extinct colubrid racer from Martinique, currently classified as critically endangered on the International Union for Conservation of Nature Red List. Mitochondrial deoxyribonucleic acid sequences were obtained from four E. cursor specimens from the Muséum national d'Histoire naturelle (Paris) collections. All sequences recovered the same haplotype and the level of divergence between E. cursor and E. juliae, from the nearby island of Dominica, was lower than between other intraspecific distances within other Erythrolamprus. Furthermore, phylogenetic analyses confirm that these two species are sister taxa and share most recent common ancestry. We discuss that published ecological data available for the sister species (E. juliae) may help to elucidate information on this species' natural history, ultimately having important implications for a future conservation management program if E. cursor is to be found. We emphasize the urgent need to conduct an exhaustive survey on the supposed last population of E. cursor at Diamond Rock to establish the survival of this species there, to understand how it may have adapted to such an ecosystem, especially in sympatry of several introduced rodent species.

“…Other species use bromeliads during the reproductive period, as calling or oviposition sites or as microhabitats for tadpole development [e.g., Physalaemus spiniger (Haddad and Pombal 1998); Aplastodiscus sibilatus (Cruz et al 2003); Dendrobates pumilio (Young 1979)]. At the other extreme, some anurans use bromeliads only as diurnal shelters [e.g., Eleutherodactylus johnstonei (Ovaska 1991); Aparasphenodon brunoi (Teixeira et al 2002); Dendropsophus nahdereri and Scinax perereca (Conte and Rossa-Feres 2006); and Scinax hayii (F. Nomura, personal observation)]. Even in those anuran species that only use bromeliad plants as diurnal shelters, diVerent degrees of specialization can be noted.…”

Nitrogen fluxes from treefrogs to tank epiphytic bromeliads: an isotopic and physiological approach

et al. 2009

Diverse invertebrate and vertebrate species live in association with plants of the large Neotropical family Bromeliaceae. Although previous studies have assumed that debris of associated organisms improves plant nutrition, so far little evidence supports this assumption. In this study we used isotopic ((15)N) and physiological methods to investigate if the treefrog Scinax hayii, which uses the tank epiphytic bromeliad Vriesea bituminosa as a diurnal shelter, contributes to host plant nutrition. In the field, bromeliads with frogs had higher stable N isotopic composition (delta(15)N) values than those without frogs. Similar results were obtained from a controlled greenhouse experiment. Linear mixing models showed that frog feces and dead termites used to simulate insects that eventually fall inside the bromeliad tank contributed, respectively, 27.7% (+ or - 0.07 SE) and 49.6% (+ or - 0.50 SE) of the total N of V. bituminosa. Net photosynthetic rate was higher in plants that received feces and termites than in controls; however, this effect was only detected in the rainy, but not in the dry season. These results demonstrate for the first time that vertebrates contribute to bromeliad nutrition, and that this benefit is seasonally restricted. Since amphibian-bromeliad associations occur in diverse habitats in South and Central America, this mechanism for deriving nutrients may be important in bromeliad systems throughout the Neotropics.
