Abstract In this study, we integrated data from more than 30 years of inventories available in the main herpetological collections Pernambuco Endemism Center (PEC), northern Atlantic Forest. We aimed to reduce Wallacean shortfall amphisbaenians and lizards (non-snake squamates) region, provide distribution maps all species, direct future survey efforts conservation strategies one most threatened portions The species list was based exclusively on records associated with vouchers localities...
We studied the diet of whiptail lizard Cnemidophorus ocellifer (Spix, 1825) and relationships between predator size prey in a Caatinga area northeastern Brazil. Lizards (N = 111) were collected during day through active search. In laboratory, we measured them registered number ingested items each category to Order, as well dimensions frequencies each. The main C. was insect larvae pupae, followed by Orthoptera, Isoptera, Coleoptera Araneae. Termites (Isoptera) important only numeric terms,...
Composition, species diversity and resource usage in terms of space time were evaluated for the lizard community Ecological Station Seridó (ESEC Seridó), Rio Grande do Norte. An observation area 150 m × (2.25 ha) was delimited surveyed monthly alternate turns (morning, afternoon night) three consecutive days from April to October 2011, covering dry rainy seasons. Fourteen belonging eight families recorded, being Tropidurus semitaeniatus most abundant. Seasonality influenced richness...
Abstract Studying species interactions in nature often requires elaborated logistics and intense fieldwork. The difficulties such task might hinder our ability to answer questions on how biotic change with the environment. Fortunately, a workaround this problem lies within scientific collections. For some animals, inspection of preserved specimens can reveal scars past antagonistic encounters, as predation attempts. A common defensive behaviour that leaves animals is autotomy, loss body...
We report here a set of observations on mating behavior and female accompaniment by the whiptail lizard Cnemidophorus ocellifer in an area Caatinga (xerophilous open forests) state Rio Grande do Norte, northeastern Brazil. observed stationary male performing repeated vibratory movements pelvis tail base upon sandy soil. Since that was front burrow which same species sheltered, we hypothesize this may be part courtship display. continued observation later, when emerged from burrow, climbed...
This study investigated the influence of seasonality on diet and foraging behavior whiptail lizard Ameivula (Cnemidophorus) ocellifera in Caatinga northeastern Brazil. Diet composition was identified through stomach analysis lizards collected monthly by active search during 2009 (rainy dry seasons) half 2010 season). Foraging one rainy month 2012, allowing us to determine percent time spent moving (PTM), number movements per minute (MPM), successful attacks prey activity. Analysis contents...
Bromeliads are important habitats for reptiles and amphibians, constantly used as shelter, refuge, foraging or thermoregulation sites due to their foliar architecture, which allows constant maintenance of humidity temperature. This study aimed identify the herpetofauna inhabiting non-phytotelmata rupicolous bromeliad Encholirium spectabile Mart. ex Schult. & Schult.f. analyze microhabitat usage these bromeliads by different species in Caatinga northeastern Brazil. From January 2011...
The Neotropical lizard Mabuya agmosticha Rodrigues, 2000 is a habitat-specialist of thorny bromeliads in rocky outcrops northeastern Brazil. Its distribution the Caatinga Domain most likely relictual. In recent years, new surveys conducted Brazil have revealed records species and also Atlantic Forest Domain. this study, we add four for M. agmosticha, extending its known geographic range states Rio Grande do Norte Paraíba. addition, investigated potential geographical using ecological niche...
Sobre a história natural do Sapo-de-chifre da Caatinga, Ceratophrys joazeirensis (Anura: Ceratophryidae), uma espécie pouco conhecida nordeste Brasil. Apresentamos aqui dados sobre reprodução, dimorfismo sexual e dieta de joazeirensis, única gênero que ocorre no Bioma brasileiro semiárido Caatinga. Os anuros foram observados coletados Município Santa Maria, estado Rio Grande Norte, O trabalho campo foi realizado à noite, durante ou após as chuvas ao longo estação chuvosa período 2010–2013....
Estudamos o uso dos recursos espaciais, temporais e térmicos pelo lagarto neotropical Ameiva ameiva durante as estaçõesseca chuvosa em um ambiente de caatinga do nordeste Brasil. Os lagartos utilizaram os hábitats micro-hábitats vegetação baixa, mas nunca foram observados no hábitat rochoso. adultos usualmente arbóreo-arbustivo, enquanto juvenis maisfrequentemente arbustivo-herbáceo. Diferenças ontogenéticas espaço parecem estar relacionadas a diferentes necessidades térmicas entre classes...
We studied the feeding ecology of a population Coleodactylus natalensis Freire, 1999, an endemic gecko Atlantic Forest fragments in state Rio Grande do Norte, northeastern Brazil. Lizards (N = 49) were collected manually through active search four habitats Parque Estadual Dunas de Natal, type locality species. In laboratory, we measured lizards and registered number consumed prey items identified to Order, its dimensions frequencies. also samples leaf litter each habitat determine...
We analyzed the diet of Amphisbaena heathi, a species with restricted geographic distribution in northeastern Brazil. also present data on morphometric and meristic characters examined specimens update species. The analysis was based contents digestive tract 21 collected two urban Atlantic Forest fragments Natal municipality, Rio Grande do Norte state, from 2008–2010. 80.1% near surface (depth ca. 3–5 cm) moist earth under leaf litter 19.9% underground (ca. 15 cm beneath surface). In total,...
Abstract The knowledge about interactions between predators and prey is essential for understanding the natural history of animals, especially snakes, which are cryptic organisms that difficult to visualize in wild. This article reports on predation lizards, frogs, bats venomous snakes by snake Philodryas nattereri , evidencing its generalist feeding habits.
Regional data on the natural history of snakes are important for understanding patterns ecological geographic variation widely distributed species. In this study, we report new dietary about South American dipsadine snake Philodryas nattereri in Caatinga and Atlantic Forest regions northeastern Brazil. Our observations wild include predation large-sized lizards ( Iguana iguana ), adult birds Columbina picui venomous toads Rhinella jimi R. granulosa Lygophis dilepis bird chicks inside nests...
Herein, we provide a new record of Cercosaura ocellata Wagler, 1830 in the Atlantic Forest biome, northeastern Brazil, and distribution map for species South America. The was Extremoz municipality, state Rio Grande do Norte, filling gap known geographic between states Ceará Pernambuco.
We reassessed the type-series of Amphisbaena lumbricalis Vanzolini, 1996 and carvalhoi Gans, 1965, two small amphisbaenid species from northeastern Brazil, to evaluate characters used diagnose distinguish them, compared these data with additional specimens four new localities. found broadly overlapping ranges diagnostic characters, no morphological traits that could support differences between A. lumbricalis. Based on similarities, distribution both species, we consider as a junior synonym...
