Death-Feigning As Defensive Behaviour in Blue-Tailed Microteiid Lizard Micrablepharus Atticolus Rodrigues, 1996 Herpetology Notes, volume 11: 1065-1067 (2018) (published online on 19 December 2018) Death-feigning as defensive behaviour in blue-tailed microteiid lizard Micrablepharus atticolus Rodrigues, 1996 Gabryella de Sousa Mesquita1, Denes Ferraz2,3,*, Werther Pereira Ramalho2,3, Iberê Farina Machado2, and Wilian Vaz-Silva4 Death-feigning or thanatosis is a defensive behaviour pattern with conspicuous black and white stripes in the in which the animal pretends to be dead when it dorsolateral region and bluish tail (Sousa, 2016), which is physically threatened by a potential predator are characteristic that may be effective to divert predator (Hamphreys and Ruxton, 2018).

The characteristics of death-feigning reported in this study for M. atticolus are similar to those previously described for Placosoma glabellum (Muscat et al., 2016) and Iphisa elegans (Machado-Filho et al., 2018), indicating that this behaviour may be shared among gymnophthalmids. Finally, death-feigning behaviour needs to be further investigated since the disclosure of these events is important not only to increase knowledge about the natural history of the species, but also provide data that can be useful to understanding how such behaviour evolved in the family.

In this study we analyzed the diet of the gymnophthalmid lizard Ecpleopus gaudichaudii Duméril & Bibron, 1839, a typical inhabitant of the forest-floor leaf litter, in an Atlantic Forest area in the state of Rio de Janeiro, southeast- ern Brazil. The 26 individuals sampled during the study had a mean snout-vent length (SVL) of 36.2 ± 4.2 mm and a mean jaw width (JW) of 4.1 ± 0.5 mm. We did not find differences in SVL between males and females, though the sexes differed in JW when the effect of body size was factored out, with females presenting higher values. The diet of the lizards was composed exclusively of arthropods, especially isopods and orthopterans.

  • Effects of Abandoned Eucalyptus Plantations on Lizard Communities in the Brazilian Cerrado
    Biodivers Conserv (2014) 23:3155–3170 DOI 10.1007/s10531-014-0771-x ORIGINAL PAPER Effects of abandoned Eucalyptus plantations on lizard communities in the Brazilian Cerrado Alison M. Gainsbury • Guarino R. Colli Received: 4 November 2013 / Revised: 11 July 2014 / Accepted: 29 July 2014 / Published online: 8 August 2014 Ó Springer Science+Business Media Dordrecht 2014 Abstract The rapid expansion of human altered landscapes affects biodiversity on every continent. A fundamental goal of conservation biologists is to understand why certain species are at risk of extinction while others are able to persist in human altered landscapes. Afforestation, the conversion of unforested lands to planted forest, is rapidly altering many natural landscapes worldwide. In the Cerrado (Brazilian savanna), a global biodiversity hotspot, a shortage of government incentives has the landscape riddled with abandoned plantation forests that are not subject to active restoration projects. Studies investigating the impacts of abandoned plantations on biodiversity are strikingly limited. We examine the effects of abandoned Eucalyptus plantations on the structure of Cerrado lizard com- munities. We assessed changes in lizard capture, richness and equitability along cerrado sensu stricto—Eucalyptus transects. Our results indicate abandoned Eucalyptus plantations have subsets of Cerrado species persisting with a great loss of endemic species. The cerrado sensu stricto—Eucalyptus linear transect analysis demonstrated distance from native habitat is positively correlated with loss of biodiversity. We performed corre- spondence analyses to summarize the variation in species captures across different sites, habitats and pitfall array positions. These analyses depicted strong species associations between habitats and their pitfall array positions. This study is the first to show the negative impacts of abandoned Eucalyptus plantations on Cerrado lizard communities, serving as a cautionary tale of Cerrado biodiversity non-resilience in abandoned Eucalyptus planta- tions.

  • Digit Evolution in Gymnophthalmid Lizards JULIANA G
    Int. J. Dev. Biol. 58: 895-908 (2014) doi: 10.1387/ijdb.140255jg www.intjdevbiol.com Digit evolution in gymnophthalmid lizards JULIANA G. ROSCITO*,1, PEDRO M.S. NUNES2 and MIGUEL T. RODRIGUES1 1Departamento de Zoologia, Instituto de Biociências, Universidade de São Paulo-SP and 2Departamento de Zoologia, Centro de Ciências Biológicas, Universidade Federal de Pernambuco, Brazil ABSTRACT The tetrapod limb is a highly diverse structure, and reduction or loss of this structure accounts for many of the limb phenotypes observed within species. Squamate reptiles are one of the many tetrapod lineages in which the limbs have been greatly modified from the pentadactyl generalized pattern, including different degrees of reduction in the number of limb elements to complete limblessness. Even though limb reduction is widespread, the evolutionary and develop- mental mechanisms involved in the formation of reduced limb morphologies remains unclear. In this study, we present an overview of limb morphology within the microteiid lizard group Gymn- ophthalmidae, focusing on digit arrangement. We show that there are two major groups of limb- reduced gymnophthalmids. The first group is formed by lizard-like (and frequently pentadactyl) species, in which minor reductions (such as the loss of 1-2 phalanges mainly in digits I and V) are the rule; these morphologies generally correspond to those seen in other squamates. The second group is formed by species showing more drastic losses, which can include the absence of an ex- ternally distinct limb in adults. We also present the expression patterns of Sonic Hedgehog (Shh) in the greatly reduced fore and hindlimb of a serpentiform gymnophthalmid.

We also summarized data on lizard faunas for nine other well-studied areas in Amazonia to make pairwise comparisons among sites. The Biogeographic Similarity Coefficient for each pair of sites was calculated and plotted against the geographic distance between the sites. A Parsimony Analysis of Endemicity was performed comparing all sites. A total of 114 species has been recorded in the four studied sites, of which 45 are lizards, three amphisbaenians, and 66 snakes. The two sites between the Xingu and Madeira rivers were the poorest in number of species, those in western Amazonia, between the Madeira and Juruá Rivers, were the richest. Biogeographic analyses corroborated the existence of a well-defined separation between a western and an eastern lizard fauna. The western fauna contains two groups, which occupy respectively the areas of endemism known as Napo (west) and Inambari (southwest). Relationships among these western localities varied, except between the two northernmost localities, Iquitos and Santa Cecilia, which grouped together in all five area cladograms obtained. No variation existed in the area cladogram between eastern Amazonia sites. The easternmost localities grouped with Guianan localities, and they all grouped with localities more to the west, south of the Amazon River.
