Última Playing dead to stay alive: death-feigning in Liolaemus occipitalis (Squamata: Liolaemidae) Biota Neotropica Santos,Maurício Beux dos; Oliveira,Mauro Cesar Lamim Martins de; Verrastro,Laura; Tozetti,Alexandro Marques. Predation is the major selective force that drives the development of a series of defense mechanisms by the species. These mechanisms are efficient in that it limits the ability of predators to detect, recognize and subdue their prey. In lizards for example, the tail loss and locomotor escape are the most common defensive behavior reported on the literature. Additionally, in response to external stimuli, some lizards exhibit a peculiar defensive behavior: death-feigning or thanatosis. Here we describe the first record of death-feigning in a population of Liolaemus occipitalis in a coastal sand dune habitat in Southernmost Brazil. A total of 86 individuals were tested. During handling 75.6% of lizards feigned death. The duration of this behavior was longer... Tipo: Info:eu-repo/semantics/other Palavras-chave: Thanatosis; Behavior; Sand-dune lizard; Pampa; Restinga. Ano: 2010 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1676-06032010000400043 Diversity and habitat use by snakes and lizards in coastal environments of southernmost Brazil Biota Neotropica Santos,Maurício Beux dos; Oliveira,Mauro Cesar Lamim Martins de; Tozetti,Alexandro Marques. This study examined species composition differences among snake and lizard assemblages from coastal dunes and restinga habitats in southernmost Brazil. Animals were collected between April 2009 and March 2010 using pitfall traps, artificial shelters, and time-constrained searches in grasslands areas susceptible to flooding. Species richness was higher in the restinga, but lower than the observed in other Brazilian biomes, possibly associated with more unstable microclimate conditions and low habitat complexity (vertical and horizontal distribution of the vegetation) in this habitat. This hypothesis is supported by the fact that the most abundant species of both snakes and lizards have fossorial habits. The assemblage of snakes is apparently mainly...

Ano: 2012 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1676-06032012000300008 Does human influence on coastal grasslands habitats affect predation pressure on snakes? Biota Neotropica Santos,Mauricio Beux dos; Oliveira,Mauro Cesar Lamim Martins de; Gonçalves,Tatiane Penteado; Almeida,Francis de Mattos; Loebmann,Daniel; Tozetti,Alexandro Marques. The loss and modification of habitats by humans have been considered key factors in the decline of diversity of species worldwide. However, the real effect caused by these disturbances on the biota is still poorly understood. The assessment of the changes in the network of interspecific interactions, such as predation rates on the native fauna, can be an important tool to diagnose the functionality of disturbed ecosystems. In this study we evaluate the predation rate on snakes in coastal grasslands in South America under human influence. Predation rate of artificial snakes, unlike that obtained in other studies, was lower in human-altered areas than preserved ones. Our findings may be due to a reduction in the abundance and/or richness of species of native...
