Riparian forests bordering open terrestrial environments may have three microhabitats differing in structure and conditions: a grassland/pasture-forest edge (GE), a forest interior (FI) and a river–forest edge. The influence of such edge effects and vegetation characteristics on spider diversity of riparian forests was evaluated in Southern Brazil. Four(More)
The distribution of beta diversity is shaped by factors linked to environmental and spatial control. The relative importance of both processes in structuring spider metacommunities has not yet been investigated in the Atlantic Forest. The variance explained by purely environmental, spatially structured environmental, and purely spatial components was(More)
The theridiid genus Dipoena Thorell, 1869 is distributed worldwide. Dipoena are recognized by male with carapace often high, cylindrical, with grooves or depression on dorsum; carapace of female rarely modified, sometimes high. In this paper six new species of Dipoena are described from Brazil, one from the state of Mato Grosso do Sul: Dipoena bonitensis(More)
Terrestrial diplopods are a diverse group of invertebrates with important ecosystem roles within soil communities, though information from the Neotropical Region is still scarce. The present study investigates the association between Diplopoda diversity and composition with vegetation structure, based on pitfall trap samples taken from three different(More)
Wetlands (e.g. ponds, meadows) can be found in many landscapes, playing an important role in maintaining regional biodiversity and supporting heterogeneous communities. Spiders are diversified predators that are highly influenced by changes in plant community structure, heterogeneous habitats sustain high spider diversity and abundance. We investigated the(More)
