Abstract:
Worm lizards (Amphisbaenia) are burrowing squamates that live as subterranean predators. Their underground existence should limit dispersal, yet they are widespread throughout the Americas, Europe and Africa. This pattern was traditionally explained by continental drift, but molecular clocks suggest a Cenozoic diversification, long after the break-up of Pangaea, implying dispersal. Here, we describe primitive amphisbaenians from the North American Palaeocene, including the oldest known amphisbaenian, and provide new and older molecular divergence estimates for the clade, showing that worm liza

Abstract:
We studied the thermal ecology of the amphisbaenian Trogonophis wiegmanni at the Chafarinas Islands (North Africa). We aimed to evaluate the extent of thermoregulation in this fossorial amphisbaenian by analyzing the relationships between environmental available operative (Te) and body (Tb) temperatures of active individuals found under stones. Amphisbaenians are typical thigmotherms that obtain heat through contact with soil and, thus, Tb was closely correlated to Te under stones. However, the comparison of Tb with Tes available in the study area indicated that Tb deviated less from the set-p

Morphological adaptations for burrowing, such as an elongated body, and a small head may constrain feeding behaviour in fossorial reptiles.

When prey diameter was narrower than gape-size, prey were consumed without prey processing; when prey diameter was wider than gape-size, B. cinereus shifted handling mode to prey processing.

Populations of terrestrial or freshwater taxa that are separated by oceans can be explained by either oceanic dispersal or fragmentation of a previously contiguous land mass.

The White-necked Hawk (Amadonastur lacernulatus) is an Atlantic Forest endemic bird of prey with a poorly known diet.

During these events, hawks were recorded grasping, killing and consuming amphisbaenids. Due to their fossorial life, worm lizards are uncommon prey items for most birds of prey and such predator-prey interaction can be related to flooded amphisbaenians galleries after heavy rain episodes.

Abstract:
This study presents original data on the reproduction and feeding ecology of two syntopic amphisbaenians, Amphisbaena munoai Klappenbach, 1969 and Anops kingi Bell, 1833, from southern Brazil. Sampling was carried out from April 2004 to April 2006 at a highland area located in São Jerônimo and Barão do Triunfo municipalities, Rio Grande do Sul, Brazil. A total of 647 amphisbaenians were collected, 510 specimens of A. munoai and 137 specimens of A. kingi, of which 130 and 93, respectively, had their gonads and gut content analyzed. Both species presented a unimodal pattern of seasonal distribut

Abstract:
Abstract Comparing reproductive tract morphology between closely-related species may reveal mechanisms and processes leading to reproductive isolation and cladogenesis. Differences in external morphology are often inconspicuous between closely-related Neotropical species, and tissue samples for DNA sequencing are usually scarce for fossorial organisms such as amphisbaenians. Therefore, comparing characters of the reproductive tract between closely related amphisbaenians may be a viable alternative to understand processes by which evolutionary lineages have diverged morphologically from common

Abstract:
There are currently 760 reptile species known in Brazil, from which about 70 are amphisbaenians with 25 species recorded in the Brazilian northeast (Vanzolini 2002; Gomes &amp; Maciel 2012; Costa &amp; Bérnils, 2014; Roberto et al., 2014). Leposternon polystegum Duméril, is a widespread species distributed in the Amazon, Atlantic Forest, Cerrado, and Caatinga biomes (Porto et al., 2000; Ribeiro et al., 2011). The diet is composed mainly by ants, termites, and coleopteran larvae (Barros-Filho &amp; Valverde, 1996; Gomes et al., 2009).

Abstract:
We present data on the diet of 15 species of snakes belonging to a community from Reserva Particular do Patrimônio Natural Feliciano Miguel Abdala, an Atlantic Forest fragment of Southeastern Brazil, based on their stomach contents. For 12 items we were able to determine the direction of the ingestion. Most snakes ingested the prey head-first. A cluster analysis was conducted with items grouped as chilopods, mollusks, adult anurans, anuran tadpoles, lizards, amphisbaenians, snakes, and rodents. The phylogenetic influence on diet preferences is discussed.
