Quantifying the biodiversity value of tropical primary, secondary, and plantation forests
TLDR
The results show that, whereas the biodiversity indicator group concept may hold some validity for several taxa that are frequently sampled, it fails for those exhibiting highly idiosyncratic responses to tropical land-use change, highlighting the problems associated with quantifying the biodiversity value of anthropogenic habitats. Expand
The cost-effectiveness of biodiversity surveys in tropical forests.
TLDR
This work presents a generic and novel framework for identifying high-performance indicator taxa that combine practical feasibility and ecological value, and illustrates the approach using a large-scale assessment of 14 different higher taxa across three forest types in the Brazilian Amazon. Expand
Macrophyte Structural Complexity Influences Spider Assemblage Attributes in Wetlands
TLDR
It is suggested that the increase in macrophyte structural complexity, primarily through vertical structure, provides additional habitat and microhabitat variability and may increase the availability of prey and shelter and even reduce intraguild predation between spiders, thereby potentially increasing density and taxa richness. Expand
The value of primary, secondary, and plantation forests for Neotropical epigeic arachnids
TLDR
The data indicate that regenerating forests are not biological deserts and can, therefore, help mitigate some of the negative effects of deforestation for epigeic arachnids and help conserve many of those species most at risk from extinction. Expand
Ami, a new Theraphosid genus from Central and South America, with the description of six new species (Araneae: Mygalomorphae)
TLDR
Females of Ami differ further from those of other theraphosid genera by their highly characteristic spermathecae: paired ventral receptacles attached to an almost discrete, semicircular, sclerotized back-plate. Expand
Arachnida at "Reserva Ducke", Central Amazonia/Brazil
TLDR
Data show, that almost one-fourth of the families presently known in the Arachnida and about 2% of the worlds described species are represented in Amazonia. Expand
Refining the establishment of guilds in Neotropical spiders (Arachnida: Araneae)
We present a refinement in the establishment of guilds in Neotropical spiders based on information assessed by assigning different levels of taxa identification, which allowed better descriptions ofExpand
The Brazilian Goblin Spiders of the New Genus Predatoroonops (Araneae: Oonopidae)
TLDR
The new endemic goblin spider genus Predatoroonops is erected for 17 new soft-bodied oonopid species from Brazil, and the type species, P. schwarzeneggeri, sp. Expand
A structured inventory of harvestmen (Arachnida: Opiliones) at Juruti River plateau, State of Pará, Brazil
The first structured inventory of harvestmen in the Brazilian Amazon Rain Forest was carried out at Juruti municipality, Para State. The sampling protocol was done in three plots of (1 ha each)Expand
