1. Extension of the geographic distribution of Plecturocebus baptista (Pitheciidae, Primates) and a possible hybrid zone with Plecturocebus hoffmannsi: evolutionary and conservation implications
RESUMO Macacos zogue-zogue (família Pitheciidae) são primatas neotropicais altamente diversificados em morfologia, ecologia e genética, com distribuição geográfica abrangente, incluindo a Floresta Amazônica, Mata Atlântica, Cerrado, Pantanal e a Caatinga. Essa diversificação, juntamente com lacunas de conhecimento, gera incertezas na taxonomia e di

3. Medium- and large-sized mammal composition in the Chapada dos Veadeiros National Park and adjacent areas, state of Goiás, Brazil
ABSTRACT The Cerrado is the second largest Brazilian biome and only 2.8% is represented by protected areas. Considering the relevance of the Cerrado and Conservation Units in preserving the mammalian diversity, we provided the first assessment of the diversity of medium- and large-sized mammal species in the Chapada dos Veadeiros National Park (CVNP) and sur

4. Cytogenetics of two hylid frogs from Brazilian Cerrado
Abstract Cytogenetic data can be useful for taxonomic and phylogenetic studies, as well as to provide information about chromosome evolution. Therefore, it may help design conservation priorities for some threatened species, such as anurans. Herein, we describe the karyotypes of Scinax constrictus and Ololygon centralis, native endemic species from the Brazi

5. Bird diversity along a gradient of fragmented habitats of the Cerrado
ABSTRACT Understanding the factors that affect biodiversity is of central interest to ecology, and essential to species conservation and ecosystems management. We sampled bird communities in 17 forest fragments in the Cerrado biome, the Central-West region of Brazil. We aimed to know the communities structure pattern and the influence of geographical distanc

6. The South-American rattlesnake Crotalus durissus: feeding ecology in the central region of Brazil
Abstract We investigated food patterns in the diet composition of 452 specimens of Crotalus durissus from Central Brazil. Thirty-three items were recorded corresponding to four categories: rodents (75.76%), marsupials (6.06%), unidentified mammals (9.09%) and reptiles (9.09%). Adults of both sexes and some juveniles feed mostly on mammals, specifically roden

7. Factors influencing seed germination in Cerrado grasses
Few studies address the ecology of herbs of Cerrado grasslands, which are ecosystems where the long dry season, high temperatures, insolation, fire and invasive grasses greatly influencing germination and the establishment of plants. We assessed germination of 13 species of Poaceae from Cerrado grasslands under nursery conditions or in germination chambers,

8. 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

9. Phenology, biometric parameters and productivity of fruits of the palm Butia capitata (Mart.) Beccari in the Brazilian cerrado in the north of the state of Minas Gerais
The fruits of the palm Butia capitata are harvested from wild populations. A lack of knowledge of their ecology has hindered the establishment of sustainable management practices. We investigated fruit biometric parameters, yield and phenology in two populations of B. capitata in the cerrado (savanna) in the north of the state of Minas Gerais, Brazil, at two

10. Taxonomic revision of Pseudolaelia Porto & Brade (Laeliinae, Orchidaceae)
Pseudolaelia is a genus endemic to eastern Brazil. The species are often epiphytes on Velloziaceae or are saxicolous, predominantly on granitic and gneissic outcrops (inselbergs) in the Atlantic Forest and, less often, in the campos rupestres (dry, rocky grasslands) of the cerrado (savanna) and caatinga (shrublands). The genus is characterized by homoblastic

11. Ecology, management and conservation of buriti (Mauritia flexuosa; Arecaceae) in swamp forest of the Central Brazil / Ecologia,manejo e conservação do buriti (Mauritia flexuosa; Arecaceae) nos brejos do Brasil Central
Florestas geram subsistência e renda para comunidades rurais, por meio do extrativismo de produtos florestais não madeireiros (PFNM), agricultura de coivara, criação de gado e porcos, etc. Estas atividades podem ser alternativas econômicas de menor impacto do que o corte seletivo de madeira e a conversão das florestas em monoculturas. Porém, a sustent

12. Ecologia de Chiroptera, em áreas de caatinga, com considerações zoológicas e zoogeográficas sobre a fauna de morcegos dos Estados da Paraíba e Ceará. / Ecology of Chiroptera in Caatinga areas, with considerate zoologiques and zoogeographic about the bat fauny of the states Paraíba and Ceará.
No bioma Caatinga, apesar deste ser o único exclusivamente brasileiro e uma das 37 grandes regiões naturais do mundo ao lado da Amazônia e do Cerrado, bem como apresentar apenas 52,6% de sua cobertura vegetal original devido ao acelerado ritmo de descaracterização e deserficação que acomete a região, a deficiência no conhecimento da diversidade, tax
