“…Sampling methods for herpetofauna can be applied in the presence or absence of the researcher in the field (heyer et al 1994, Franco et al 2002, Willson and Dorcas 2004, Silveira et al 2010. The most used methods to capture snakes that require the presence of researchers in the field are: timeconstrained search (TCS), transects and occasional encounters by the research staff (OE) (Franco et al 2002).…”

“…Among the traps, the pitfall traps (PIT) are the most used in neotropical environments, while other techniques, such as "funnel traps", "glue traps", and artificial shelters are still rarely used possibly because of limited funding (Cechin and Martins 2000, Auricchio and Salomão 2002, Sawaya et al 2008, Silveira et al 2010.…”

The choice of sampling methods is a crucial step in every field survey in herpetology. In countries where time and financial support are limited, the choice of the methods is critical. The methods used to sample snakes often lack objective criteria, and the traditional methods have apparently been more important when making the choice. Consequently researches using not-standardized methods are frequently found in the literature. We have compared four commonly used methods for sampling snake assemblages in a semiarid area in Brazil. We compared the efficacy of each method based on the cost-benefit regarding the number of individuals and species captured, time, and financial investment. We found that pitfall traps were the less effective method in all aspects that were evaluated and it was not complementary to the other methods in terms of abundance of species and assemblage structure. We conclude that methods can only be considered complementary if they are standardized to the objectives of the study. The use of pitfall traps in short-term surveys of the snake fauna in areas with shrubby vegetation and stony soil is not recommended.

ABSTRACT. Diversity analysis by partition is an approach employed in order to understand how communities spatially structure themselves and the factors that operate in the generation and maintenance of distribution patterns. We examined the spatial structure of species diversity of four taxonomic groups, with diff erent dispersal abilities, in 16 forest fragments in the southern region of the state of Minas Gerais, Brazil. Specifi cally, we tested: i) if the similarity in species composition would be negatively related to geographical distance between the 16 fragments; and ii) if the beta diversity of the diff erent groups could be negatively related to their dispersal abilities. Alpha diversity and the compositional similarity between localities were both low. Beta diversity was not correlated with distance for any of the groups. Primates, followed by birds, showed a higher tendency of forming similarity groupings, although in a manner that was independent from distance between fragments, as well as showed the lowest beta diversity relative values. Spermatophytes and amphibians did not defi ne groupings and presented the highest values of beta diversity. We interpreted such results as indications that the groups with higher dispersal ability (primates and birds) tend to reach, on average, farther localities and, therefore, to defi ne more similar groupings (low beta diversity). The groups with lower dispersal ability (spermatophytes and amphibians) showed the opposite tendency. Although most of the species were restricted to few localities, contributing to the low similarity, beta and gamma diversity values showed the extent which the localities are, respectively, diff erent and complementary to each other in terms of species composition. Such features reinforce and justify future conservation initiatives, both in local and regional levels.KEYWORDS.

Tanto a diversidade alfa quanto a similaridade composicional entre as localidades foram baixas. A diversidade beta não esteve correlacionada com a distância para nenhum dos grupos.

“…O inventário da fauna, quando realizado sobre táxons que indicam as respostas à perturbação de outros grupos de invertebrados em ambientes sujeitos à degradação, tem sido considerado ferramenta valiosa na identificação de espécies bioindicadoras da qualidade de determinados ambientes (LUTINSKI; GARCIA, 2005;SILVEIRA et al, 2010). As formigas são particularmente apropriadas na realização de inventários e programas de monitoramento ambiental devido à maioria das espécies serem estacionárias, apresentarem ninhos perenes e com áreas de forrageamento próximas a esses ninhos.…”

Resumo: Os formicídeos constituem um dos grupos mais importante de insetos sociais do solo, apontados como potenciais indicadores biológicos da degradação ambiental e fornecedores de informações importantes em planos de manejo e conservação de uma dada região. Assim, objetivou-se com este trabalho inventariar a composição da assembleia de formigas e estabelecer as espécies predominantes, utilizando dois diferentes métodos de coleta (pitfall e isca de sardinha), em ecossistema de savana amazônica. Abstract:The formicidae comprise one of the most important groups of social soil insects, identified as potential biological indicators of environmental degradation, and which provide important information in the management and conservation plans for any given region. The aim of this work therefore, was to inventory the composition of ant assembly and establish the predominant species, using two different collection methods (pitfall trap and sardine bait), in a savannah ecosystem of the Amazon. The ants were collected at six different times from December 2010 to January 2011. There were 12 plots, each 250 m in length, in which there were 10 sampling points spaced 25 m apart. At each point, two collection methods were used: pitfall trap and sardine bait, giving 120 subsamples per method. After collection, the samples were taken to the Aquatic Invertebrate Laboratory of the Centre for Biodiversity (CBIO/UFRR) for sorting, and the specimens placed into bottles containing 70% alcohol for later taxonomic classification. Identification of the formicidae as to species and morphospecies was carried out at the National Research Institute of the Amazon (INPA). All materials were deposited in the invertebrate collection of INPA. It was found that the genera with greater occurrence were Camponotus, Crematogaster and Dorymyrmex, while those with the greatest species richness were Pheidole, Solenopsis and Camponotus. The species Crematogaster abstinens and Camponotus novogranadensis were predominant in the area of savannah under study. This is the first record of Kalathomyrmex emeryi in the State of Roraima. The collections made with pitfall traps were more efficient for evaluating ant richness.
