Article
Full-text available
Viviparity has evolved more times in squamates than in any other vertebrate group; therefore, squamates offer an excellent model system in which to study the patterns, drivers and implications of reproductive mode evolution. Based on current species distributions, we examined three selective forces hypothesized to drive the evolution of squamate vi...

We examined the taxonomy of the minute desert geckos of the Tropiocolotes nattereri species complex using the largest morphological sampling, and the first molecular assessment of intraspecific diversity within this complex. We examined variation in mitochondrial and nuclear markers (12S, ND2, c-mos and MC1R) of 30 samples and analyzed the external...

We present a list of amphibians and reptiles collected during six field surveys in the municipalities of Tailândia, Tomé-Açu and Moju, region of the Belém area of endemism, eastern Amazonia, Brazil. We conducted surveys on several fragments of the Amazon rainforest located in a matrix of palm oil plantations (Elaeis guineensis) and/or old pastures...
Article
en Alopoglossus is a Neotropical lizard genus the taxonomy of which has extensively evolved over the past decade. Previous works suggest that many species still remain unnamed in this genus. Here, we expand the knowledge of Alopoglossus diversity in Amazonian lowlands. Molecular phylogenetic relationships, and species boundaries, were inferred base...
Article
Our knowledge of the conservation status of reptiles, the most diverse class of terrestrial vertebrates, has improved dramatically over the past decade, but still lags behind that of the other tetrapod groups. Here, we conduct the first comprehensive evaluation (~92% of the world's ~1714 described species) of the conservation 1 Joint senior authors...
Article
Full-text available
The Levant represents one of the most important reptile diversity hotspots and centers of endemism in the Western Palearctic. The region harbored numerous taxa in glacial refugia during the Pleistocene climatic oscillations. Due to the hostile arid conditions in the warmer periods they were not always able to spread or come into contact with popula...
Article
Two species of Alopoglossus (A. angulatus and A. meloi) were recognized to occur in the Guiana Shield lowlands, northeastern Amazonia. A third group of populations forming a distinct genetic lineage related to Alopoglossus avilapiresae was recently documented in the region. The Guiana Shield lowlands area also encompasses the type locality of Alopo...
Article
Among the currently recognized species of Alopoglossus, the Amazonian Alopoglossus angulatus has the widest distribution. We here analyse variation in scutellation and morphometrics of A. angulatus by examining 785 specimens of Alopoglossus. We also analyse intra- and interspecific genetic structure and differentiation using two mitochondrial (Cytb...
Article
Aim Clutch size is a key life‐history trait. In lizards, it ranges over two orders of magnitude. The global drivers of spatial and phylogenetic variation in clutch have been extensively studied in birds, but such tests in other organisms are lacking. To test the generality of latitudinal gradients in clutch size, and their putative drivers, we pres...

Abstract Ecological requirements and environmental conditions can influence diversification across temporal and spatial scales. Understanding the role of ecological niche evolution under phylogenetic contexts provides insights on speciation mechanisms and possible responses to future climatic change. Large‐scale phyloclimatic studies on the megadiv...

I describe a new species of Alopoglossus from the Southern Guiana Shield in northern Brazilian Amazonia. The new species morphologically resembles A. angulatus in having scales on sides of neck similar in shape to dorsals, nongranular, keeled, and imbricate. Nonetheless, the presence of four pairs of chin shields, with the third pair heptagonal and...

We describe a new species of Tupinambis from central South America in a transitional region between Amazonia, Cerrado, and Pantanal. The new species differs from its congeners by the number of femoral pores, posterior gulars, and mesoptychial scales and by color pattern. It is partially sympatric with Tupinambis cuzcoensis, Tupinambis longilineus,...

Full-text available
We present distribution data of all Anguidae, Scincidae, and Teiidae lizards known from the Brazilian Amazonia, totaling 29 species-level taxa, belonging to 14 genera. This represents 11 more species-level taxa than previously reported for these families in this area. Data were based on literature and 46,806 specimens deposited in three North Ameri...
Article
Full-text available
Predation has been suggested to play a major role in the evolution of primate ecology, although reports of predation events are very rare. Mammalian carnivores, raptors, and snakes are known predators of Neotropical primates, and most reported attacks by snakes are attributed to Boa constrictor (terrestrial boas). Here, we document the predation of...

A new species of Bachia of the B. heteropa group is described from the Parque Nacional Montanhas do Tumucumaque in northeastern Amazonia, Amapá State, Brazil. The new species morphologically resembles B. heteropa and B. guianensis. Nonetheless, the absence of interparietal and prefrontal scales, and the number of supraciliary scales, can distinguis...

One of the most commonly used sampling techniques to capture leaf litter amphibians, lizards and small mammals is a set of pitfall traps with drift fences. However, there are still many speculations concerning the effectiveness of different designs of pitfall traps and the most adequate size of each trap. To address this problem, we conducted the f...

Full-text available
Plantations and secondary forests are becoming dominant components of many tropical forest landscapes. Yet we have an insufficient understanding of the value of these habitats for biodiversity conservation, and almost none for most arthropods in species-rich tropical forests. We sampled epigeic arachnids (Amblypygi, Araneae, Opiliones, Scorpiones,...

Full-text available
Biodiversity loss from deforestation may be partly offset by the expansion of secondary forests and plantation forestry in the tropics. However, our current knowledge of the value of these habitats for biodiversity conservation is limited to very few taxa, and many studies are severely confounded by methodological shortcomings. We examined the cons...
