Ecologically-related variation of digit morphology in Cyrtodactylus (Gekkota, Squamata) reveals repeated origins of incipient adhesive toepads
<p>The exploitation of different locomotor substrates in different ecological niches has driven the evolution of specialized morphological structures, and similar ecological demands, such as the structure of the microhabitat, often lead to convergent or parallel evolution. The evolution of adhesive toepads in geckos remains understudied because of the paucity of phylogenetically informed investigations of candidate clades exhibiting purported incipient expression of these (i.e., species having evolved some, but not all, parts of the complex adhesive system of pad-bearing geckos). Using <em>Cyrtodactylus</em>, a speciose genus with well-established ecotypes, we tested the hypothesis that microhabitats that require more climbing will lead to the acquisition of incipient adhesive morphology. We measured subdigital scale area, a proxy for adhesive toepad evolution, and quantified subdigital scale shape for 77 of the 354 described species, including at least one representative of each ecotype. Subdigital scale area increased from terrestrial through generalist and saxicoline (rock-dwelling) to arboreal ecotypes, with subdigital scale shape evolving from ancestral conditions for padless lizards to lateromedially expanded lamella-like scales only in the arboreal ecotypes. This significant link between phenotype and environment supports the contention that scansorial, and particularly arboreal, <em>Cyrtodactylus</em> ecotypes have evolved incipiently expressed adhesive toepads. This highlights the suitability of this genus as a model system for studying the ecology and evolution of adhesive toepads as well as being a promising candidate for research on adaptive radiations.</p>
Videos of the new specimens of Helicops boitata (Serpentes: Dipsadidae: Hydropsini), with data on morphological variation and behavior
<p>We report information on morphological variation and behavior of the recently described watersnake <em>Helicops boitata</em>, previously known strictly from the holotype. Our data come from five new specimens fortuitously found in a private area near the type locality, in the Brazilian Pantanal wetlands. The expanded sample revealed polymorphism in at least two scalation features assumed as diagnostic of the species (i.e., undivided condition of the cloacal plate and nasal scales) and confirmed the uniqueness of the ventral color pattern, as well as the divided condition of the foremost ventral shields. Besides, as reported for the holotype, three individuals collected alive also exhibited harmless behavior when handled, a rather unusual feature among snakes of the genus <em>Helicops</em>. Other new behavioral observations include a mostly nocturnal activity (in contrast with the previous data) and the ability to dig galleries in the soft substrate when attempting to escape. The finding of five individuals very close to each other suggest aggregations in habitats retaining humidity in the dry season of the Pantanal. Low abundance rates and possible habitat restrictions might render <em>Helicops boitata</em> particularly susceptible to seasonal fire episodes that consume large extensions of the wetlands, including dry swamps in which aquatic reptiles find refuge during the seasonal droughts.</p>
