A survey of the termite fauna (Isoptera) of an eucalypt plantation in central Brazil.
The termite fauna of a plantation of Eucaliptus urophylla S.T. Blake (Myrtales: Mytaceae) in Buritis, Minas Gerais, was manually sampled in 12 transects. The assemblage contained 28 species belonging to Termitidae and Rhinotermitidae. This assemblage corresponds to a subset of the native fauna of the cerrado previously present in this region. Compared to the original native fauna, it has a lowe...
متن کاملTwenty seven new species of Orthocentrus (Hymenoptera: Ichneumonidae; Orthocentrinae) with a key to the Neotropical species of the genus.
We describe 27 new species of parasitoid wasps of the genus Orthocentrus (Ichneumonidae: Orthocentrinae) from the Neotropical region, where previously only one species of the genus (O. insularis Ashmead) was known, and provide a key to all described Orthocentrus species of the region. Based on previous studies and additional material that we have seen from the region, describing these species i...
متن کاملThe hyporheic zone and its functions: revision and research status in Neotropical regions.
The hyporheic zone (HZ), as the connecting ecotone between surface- and groundwater, is functionally part of both fluvial and groundwater ecosystems. Its hydrological, chemical, biological and metabolic features are specific of this zone, not belonging truly neither to surface- nor to groundwater. Exchanges of water, nutrients, and organic matter occur in response to variations in discharge and...
متن کاملOrchid bee fauna (Hymenoptera: Apidae: Euglossina) of Atlantic Forest fragments inside an urban area in southeastern Brazil.
Male orchid bees were collected by chemical baiting in four forest fragments in parks of the city of Belo Horizonte, Minas Gerais, southeastern Brazil. One thousand three hundred and twenty-five males belonging to 14 species were captured within one year. The capture data were compared through correlation tests. The data suggest that abundance of orchid bees tend to increase with fragment size,...
متن کاملDiversity and distribution of orchid bees (Hymenoptera: Apidae) with a revised checklist of species.
The aim of this study was to investigate the diversity and distribution patterns of orchid bees (Euglossina). Cluster and correlation analyses were applied to data extracted from 28 orchid-bee surveys throughout the Neotropical Region. The 28 sampling sites were grouped in three main biogeographic areas that roughly correspond to the Amazonian Basin, the Atlantic Forest and Central America. The...
