Florestas estacionais no Pantanal, considerações florísticas e subsídios para conservação. Repositório Alice
DAMASCENO JUNIOR, G. A.; POTT, A.; POTT, V. J.; SILVA, J. dos S. V. da..
Foi feita uma atualização do conhecimento sobre Florestas Estacionais no Pantanal, em grande parte baseado em dados dos Projetos PROBIO-Pantanal e GeoMS. É apresentado um mapa com as principais manchas de florestas e contatos florísticos, baseado em imagens de satélite e uma tabela comparativa, com 60 espécies. No Pantanal ocorrem poucas áreas grandes de Florestas Estacionais: Matas do Cedro, do Fuzil, do Bebe (RPPN do SESC) e do Soldado, e outras menores espalhadas tais como os capões do Abobral e SE da Nhecolândia, cordilheiras no Sul de Poconé, Aquidauana, Miranda, Nabileque e Porto Murtinho, total estimado de 6.256,4 km2. A maioria das áreas encontra-se no norte do Pantanal nas Bacias dos rios Cuiabá, São Lourenço e Paraguai; no sul apenas o baixo...

Influence of pitfall trap size and design on herpetofauna and small mammal studies in a Neotropical Forest Rev. Bras. Zool.
Ribeiro-Júnior,Marco A; Rossi,Rogério V; Miranda,Cleuton L; Ávila-Pires,Teresa C. S.
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 first standardized comparison of patterns of species richness, rank-abundance, and community structure of leaf litter amphibians, lizards and small mammals for two trap designs (I and Y format) and three bucket sizes (35, 62, and 100 L) in a Neotropical forest. Results are very similar for the herpetofauna, regardless of the pitfall trap design or size used, while for small mammals values of species richness were...

Population structure of Eschweilera coriacea (DC.) S. A. Mori in forest fragments in eastern Brazilian Amazonia Rev. Bras. Bot.
Lopes,Maria Aparecida.
The population structure of a common canopy tree was examined in three sites to investigate the possible effects of forest fragmentation in eastern Amazonia. Evidence for the escape hypothesis of differential seed/seedling survival was evaluated. Two 1 ha plots were established at each site and all individuals of Eschweilera coriacea (DC.) S. A. Mori over 1 m tall were tagged, measured and mapped. Smaller individuals were recorded in the same way within subplots. Mature individuals were abundant at all sites with densities of 32-52 ha-1. The species exhibited substantial regeneration, although total population density varied fourfold among sites (1,256-4,805 individuals ha-1). Overall, juveniles were clumped while adults were randomly distributed. The...

Structure and floristic diversity of remnant semideciduous forest under varying levels of disturbance Acta Botanica
Gris,Darlene; Temponi,Lívia Godinho; Damasceno Junior,Geraldo Alves.
The perturbation of Neotropical forests generates large disturbances in biological communities. The species that suffer least from the resulting habitat fragmentation are the pioneers, because they possess greater ability to inhabit disturbed environments. Therefore, it is expected that species diversity will be greater in areas subjected to intermediate disturbance, such as the opening of gaps, because a large number of pioneer species will develop and coexist with species of more advanced successional stages. This study aimed to compare two forest remnants that differed in size and disturbance intensity, in order to determine the effects of disturbances on species diversity and the size ratios of individual trees. This was accomplished with comparative...
