1. Natural history of Micrablepharus maximiliani (Squamata: Gymnophthalmidae) in a Cerrado region of northeastern Brazil
Micrablepharus maximiliani (Reinhardt & Luetken, 1861) is a microteiid lizard widely distributed in the open areas of South America. Little is known about its ecology and reproductive biology. Here, we analyzed aspects of the natural history of a population of M. maximiliani from a Cerrado area in the state of Piauí, northeastern Brazil. Our results suggest

2. Distribuição, nicho potencial e ecologia morfológica do gênero enyalius (squamata, leiosauridae) : testes de hipotéses para lagartos de florestas continentais brasileiras
In the first chapter, we saw that the main factors affecting the Enyalius¿ geographical distribution were the annual mean temperature, latitude, and the mean diurnal temperature, which indicates a possible thermal adaptation as a base to explain the group distribution. Enyalius distribution was reflected in the morphological geographical variation, as demon

3. Reproductive ecology and diet of Cnemidophorus ocellifer Spix 1825 (Squamata: Teiidae) in a coastal area from northeastern Brazil / Ecologia reprodutiva e dieta de Cnemidophorus ocellifer Spix 1825 (Squamata: Teiidae) em Ãrea de tabuleiro no nordeste do Brasil
Chapter 1:Reproduction of Cnemidophorus ocellifer was studied based on data collected from September 2009 to August 2010 in a coastal area of the SÃo GonÃalo do Amarante municipality, CearÃ, Brazil. Lizards were captured by manual collection, with the aid of pressure rifle or tourniquet and, after dead, individuals were dissected for sex determination by

4. Living in a caatinga-rocky field transitional habitat: ecological aspects of the whiptail lizard Cnemidophorus ocellifer (Teiidae) in northeastern Brazil
The ecology of the active forager lizard Cnemidophorus ocellifer (Spix, 1825) was studied to analyze food habits, thermal ecology and habitat use, in the Morro do Chapéu municipality (11º29'S, 41º07'W), state of Bahia, Brazil. Lizards (N = 34) were collected with rubber bands or with an air rifle and, for each individual, we recorded cloacal temperature (

5. HistÃria natural das serpentes Oxibelis aeneus (Wagler, 1824) (Squamata, Colubridae) e Philodryas nattereri Steindachner, 1870 (Squamata, Dipsadidae) em domÃnio de caatinga no estado do Cearà / Natural history of snakes Oxibelis aeneus (Wagler, 1824) (Squamata, Colubridae) and Philodryas nattereri Steindachner, 1870 (Squamata, Dipsadidae) in the area of caatinga in the state of CearÃ
It is presented a detailed study on the ecology of two species of snakes that occur on the state of CearÃ, Oxybelis aeneus (Wagler, 1824) and Philodryas nattereri Steindachner, 1870. Both species could be found in the field during all months of the year, O. aeneus presented a peak during the dry season while P. nattereri were more easily found during the ra

6. Aspectos evolutivos da história de vida e estrutura da casca do ovo de lagartos tropiduríneos / Evolutive aspects of life history and eggshell morphology of Tropidurinae lizards
In lizards, life history components have great phenotypic plasticity and evolve in a correlated way. Clutch size, for example, tends to be positively correlated to body size of gravid females, when comparing different evolutive lineages or different individuals, though some kinds of habit seems to restrict larger clutches. There are indications that other fa

7. ECOLOGIA DE Tropidurus torquatus (SQUAMATA: TROPIDURIDAE) NO BIOMA PAMPA, EXTREMO SUL DO BRASIL / ECOLOGY OF Tropidurus torquatus (SQUAMATA: TROPIDURIDAE) IN THE PAMPA BIOME, SOUTHERN BRAZIL.
Lagartos são considerados organismos modelos em ecologia, possibilitando o entendimento de padrões e relações entre organismos e ambiente. Tropidurus torquatus é uma espécie amplamente distribuída, com populações vivendo em diversos habitats e sob diferentes pressões ambientais. Apesar disso, diversos aspectos da ecologia da espécie são desconhec

8. Ecologia e modelagem da distribuição dos sítios de nidificação do jacaré-açu (Melanosuchus niger) em uma área de várzea da Amazônia Central, Brasil
The black caiman, Melanosuchus niger, is primarily an Amazonian species, its largest populations are associated mainly with interior várzea areas, but its nesting ecology related with these hydrologic dynamic environments is still poorly understood. The objectives of this study were related to the generation of information on the nesting ecology of this spe

9. Uma ecologia incomum para o gênero Cnemidophorus: o caso de Cnemidophorus lacertoides (Squamata: Teiidae) em um habitat de restinga do sul do Brasil / An usual ecology among whiptails : the case of Cnemidophorus lacertoides of a restinga habitat, South Brazil
This study presents aspects of the ecology of the whiptail lizard Cnemidophorus lacertoides at the restinga habitat of Dunas da Joaquina, in Santa Catarina State, southern Brazil. This population presents the known northernmost record for the species. The lizards were collected during the day, on December of three consecutive years, using rubber bands and gl

The present dissertation investigated about behavior microhabitat selection by tartaruga (Podocnemis expansa), iaçá (P. sextuberculata) and tracajá (P. unifilis) in Abufari Biological Reserve, Amazonas. Were monitored the turtles reproductive periods (August - December) of the 1998-2004 years. The first specie at nesting was iaçá, after tartaruga and la

12. Ecologia geografica de Tropidurus torquatus (Squamata : Tropiduridae) em areas de restinga da costa sudeste e sul-nordeste do Brasil : aspectos reprodutivos, ecologia termica e comunidades de nematodeos associados
Studies of geographical ecology can detect variation in a species ecological attributes along its geographical range, and determine the extent to which historical factors and/or local environmental factors can explain such variations. The wide geographic distribution of the tropidurid lizard Tropidurus torquatus makes it a good model for geographical ecology
