1. Macrophyte functional composition is stable across a strong environmental gradient of a Neotropical floodplain
ABSTRACT Ecological communities are compared by the similarity or distinctness of their species. Taking into account community composition at a determined site, one could expect a similar reasoning to explain differences in both taxonomic and functional composition due to environmental gradients. We aim to evaluate spatial variation in functional composition

2. Taxonomic distinctness and conservation of a new high biodiversity subterranean area in Brazil
Subterranean environments, even though they do not possess a primary production (photosynthesis), may present high biodiversity, faunistic originality, endemism, phylogenetic isolations and unique ecological and/or evolution events, in addition to rare taxa. Studies investigating the biological diversity in Neotropical caves are relatively rare and recent, a

3. Orb-weaving spider diversity in the Iberá Marshlands, Argentina
The Iberá Marshlands RAMSAR reserve, in the northeast of Argentina, is one of the largest and most important wetlands of America. In this study we assess orb-weaving spider (Araneae: Orbiculariae) diversity in this reserve, analyzing different facets of local diversity (species richness, diversity, evenness and taxonomic distinctness), and the contribution

4. Spatial distribution of Chironomidae (Diptera) in streams from north of Serra do Mar, São Paulo state / Distribuição espacial de Chironomidae (Diptera) em riachos da região norte da Serra do Mar, Estado de São Paulo
O presente trabalho teve como objetivo testar se os fatores ambientais cobertura vegetal, estrutura ambiental, vazão e características físicas e químicas da água (pH, oxigênio dissolvido, temperatura da água e condutividade) podem predizer a abundância, a diversidade e a composição de Chironomidae em riachos. As coletas foram realizadas em riachos

5. Tree species community diversity: aplication of taxonomic distinctness indices in three forest phytophysionomies in São Paulo State / Diversidade de espécies em comunidades arbóreas: aplicação de índices de distinção taxonômica em três formações florestais do Estado de São Paulo
This research is part of the project Biota / FAPESP, "Tree Species Biodiversity Inventory Methods, and analised floristic structural differences among three areas. In Assis Ecological Station, Forest Savanna area were sampled 102 species, 72 genus and 43 families, 67% of this species were exclusive of this phytophisiognomy. Semideciduous seasonal forest in t

6. Estrutura de assembléias de Vespoidea solitários (Insecta: Hymenoptera) ao longo de um gradiente altitudinal no Parque Estadual da serra do Mar, São Paulo, Brasil / Structure of solitary Vespoidea (Insecta: Hymenoptera) assemblage along a altitudinal gradient in the Serra do Mar State Park, São Paulo, Brazil
The present study aims to investigate: 1. the diversity of solitary Vespoidea along an altitudinal gradient on the Cuzcuzeiro Mountain in the Serra do Mar State Park, São Paulo, Brazil, 2. to investigate the presence of diversity patterns along the gradient, 3. to check the influence of climatic conditions on the establishment of these patterns and 4. to ac

7. Sampling of tree species diversity in tropical forests: patterns and limitations of some measures / Amostragem da diversidade de espécies arbóreas em florestas tropicais: padrões e limitações de algumas medidas
The description of species accumulation patterns with the increase of sampled area using the species accumulation curve has many applications to plant community studies. The use of this relation as a tool to determine the sampling sufficiency in phytosociological studies, therefore, shows methodological problems such as the arbitrariness in the order of samp

8. Diversidade taxonômica e formas de vida em cerrados hiperestacional e estacional no Brasil Central (Parque Nacional das Emas, GO).
As savanas, incluindo o cerrado, são caracterizadas por uma pronunciada estacionalidade, na qual a seca define o funcionamento da comunidade. No entanto, as savanas hiperestacionais experimentam, além da seca, um alagamento na estação chuvosa. Uma vez que o alagamento pode causar extinções locais de espécies intolerantes, nós nos perguntamos: As esp�

9. Hominid mandibular corpus shape variation and its utility for recognizing species diversity within fossil Homo
Mandibular corpora are well represented in the hominin fossil record, yet few studies have rigorously assessed the utility of mandibular corpus morphology for species recognition, particularly with respect to the linear dimensions that are most commonly available. In this study, we explored the extent to which commonly preserved mandibular corpus morphology
