COMMUNITY ECOLOGY Ecological release in lizard assemblages of neotropical savannas
We compare lizard assemblages of Cerrado and Amazonian savannas to test the ecological release hypothesis, which predicts that niche dimensions and abundance should be greater in species inhabiting isolated habitat patches with low species richness (Amazonian savannas and isolated Cerrado patches) when compared with nonisolated areas in central Cerrado with greater species richness. We calculat...
متن کاملSpecies richness and structure of three Neotropical bat assemblages
We compared the assemblages of phyllostomid bats in three Neotropical rainforests with respect to species richness and assemblage structure and suggested a method to validate estimates of species richness for Neotropical bat assemblages based on mist-netting data. The fully inventoried bat assemblage at La Selva Biological Station (LS, 100 m elevation) in Costa Rica was used as a reference site...
متن کاملContrasting species and functional beta diversity in montane ant assemblages
AIM Beta diversity describes the variation in species composition between sites and can be used to infer why different species occupy different parts of the globe. It can be viewed in a number of ways. First, it can be partitioned into two distinct patterns: turnover and nestedness. Second, it can be investigated from either a species identity or a functional-trait point of view. We aim to docu...
متن کاملCONSERVATION BIOLOGY AND BIODIVERSITY Ground Ant Diversity (Hymenoptera: Formicidae) in the Iberá Nature Reserve, the Largest Wetland of Argentina
The Iberá Nature Reserve in northeastern Argentina protects one of the largest freshwater wetlands and reservoirs of species in South America. However, key invertebrate groups such as the ants (Hymenoptera: Formicidae) remain almost unknown.Themainobjective of thiswork was to study the ground ant diversity in four main habitats of Iberá: grasslands, savannas, forests, and ßoating islands. Pitfa...
متن کاملSignificant reproductive skew in the facultatively polygynous ant Pheidole pallidula.
Reproductive skew - the extent to which reproduction is unevenly shared between individuals in a social group - varies greatly between and within animal species. In this study, we investigated how queens share parentage in polygynous (multiple queen) colonies of the Mediterranean ant Pheidole pallidula. We used highly polymorphic microsatellites markers to determine parentage of gynes (new quee...
