“…These periods correspond to those with more frequent occurrence of spiders associated with their canopies. This fluctuation probably reflects the greater supply of potential prey, caused by changes in canopy structure, e.g., the advent of new foliage and flowering which increase the availability of resources for herbivorous species that may be potential prey for spiders (e.g., Marques et al 2006). The change in the canopy structure of V. divergens expands the area that can be used by spiders (immatures and adults) for fixing their webs, as well as foraging and refuge areas, mainly for immatures, representing the majority of the assemblage.…”

“…Vochysia divergens is considered invasive to native pastures, posing a problem for the local people, who rely on native grasslands for livestock (Pott & Pott 1994, nunes-da-Cunha et al 2000, nunes-da-Cunha & Junk 2004. While V. divergens is characterized as a problem for landowners, it is ecologically important as a habitat and refuge for the wildlife (Pott & Pott 1994, FassnaCht 1998, Marques et al 2006, mainly when it is a fully grown tree (nunes-da-Cunha & Junk 2014).…”

ABSTRACT. This study describes the composition and temporal variation of the spider assemblage (Arachnida: Araneae) The spider assemblage is affected by changes in the habitat structure, especially by the seasonal hydrological regime and variations in the phenology of V. divergens. The assemblage is composed of different groups of spiders. The dominant taxa and behavioral guilds differ in the different seasonal periods. Spiders were more abundant during the dry and rising water seasons, most likely reflecting a greater supply of potential prey, associated with new foliage and flowering at the canopy.The displacement of soil dwelling spiders to the trunks and canopies before and during the seasonal floods can change the structure and composition of the canopy assemblages. Oonopidae, Gnaphosidae and Caponiidae, were more frequent during the rising and high water seasons, which indicates that these taxa use the canopies of V. divergens as a refuge during the seasonal flooding in the Pantanal.

“…The greatest species richness in V. divergens canopies compared to that obtained in the soil environment is compatible to which was recorded in "igapó" areas (permanently flooded areas) in central Amazonia , when they found that the canopies and epiphytes house a lot more species of Pseudoscorpiones than the forest floor. In the Pantanal, sampling in canopies of different plant species has demonstrated the importance of Pseudoscorpiones in the composition of these communities (Marques, Adis, Nunes-da-Cunha, & Santos, 2001;Santos, Marques, Adis, & Musis, 2003;Marques et al, 2006;Battirola et al, 2007). In general, in spite of the Pseudoscorpiones assemblage presenting heterogeneous distribution among forest strata, no temporal variation was observed over the different seasonal periods for the abundance and richness of the pseudoscorpion species in each evaluated habitat, despite the specificities of each.…”

Pseudoscorpions embrace a diverse group of arachnids with approximately 3 500 species that occur in various habitats, such as soil, leaf litter, caves and canopies. This study aimed at evaluating the relationship between the pseudoscorpion assemblages in soil, termite nests, tree trunks and canopies, as well as the temporal distribution as to the abundance and richness of species in these habitats. For this purpose different sampling techniques were applied in an integrated manner in distinct habitats of a seasonally flooded monodominant forest in the Northern Pantanal of Mato Grosso, Brazil. Data regarding the abundance and richness of assemblage species were organized by means of the Non-Metric Multidimensional Scaling (NMDS). A total of 2 068 Pseudoscorpiones distributed in seven families and 18 species were captured. Chernetidae (8 spp.) and Withiidae (5 spp.) predominated, while Atemnidae, Cheiridiidae, Geogarypidae, Lechytiidae and Olpiidae were present with only one species each. Terrestrial fauna was more abundant (1 035 ind.; 50.0 % of the total catch) with three families and 10 species. In the arboreal fauna (712 ind.; 34.4 %), four families and 13 species were found. Termite mounds (321 ind.; 15.6 %) corresponded to the habitat with the least number of individuals, however, five families and nine species were identified, including Parachernes sp. 2, Geogarypus sp. and Olpiolum sp., not found in other analyzed habitats in this forest. The analyses did not show any temporal variation as to abundance or richness of Pseudoscorpiones in each evaluated habitat; however, the analysis showed that the edaphic environment (soil + termite nests), tree trunks and tree canopies are distinct habitats in relation to the composition of the assemblage. The occurrence of typical terricolous (e.g. Parawithius sp., Withiidae gen. sp. and Parachernes sp.) and other arboricolous (e.g. Cheiridium sp., Americhernes sp. and Lustrochernes sp.) species highlights the vertical stratification of the assemblage present in this floodplain forest in the Pantanal of Mato Grosso.

“…Popularmente conhecidos como "capões", esses fragmentos naturais se enquadram plenamente como modelo para testar relações de espécie-área de forma natural (borDignon et al 2007) e compreender como os padrões de distribuição das espécies é afetado em ambientes fragmentados e com efeitos de distúrbios sazonais bem definido. Mesmo sendo um ambiente propício para esses estudos, o Pantanal ainda é pouco estudado em relação ao comportamento da fauna edáfica (corrêa et al 2006; battirola et al 2010) sendo dado mais enfoque a fauna associada à árvores ou dossel (battirola et al 2004, 2007castilho et al 2005;Marques et al 2006).…”

EntomoBrasilis 6 (3): 173-177 (2013) EcologiaResumo. A configuração do habitat é um dos fatores que pode influenciar a distribuição dos organismos. O pantanal por apresentar mosaico natural de formações se enquadra para testar tais afirmações. O presente estudo teve como objetivo avaliar se a distância e o tamanho de capões afetam a composição da comunidade de artrópodes testando a hipótese de que quanto maior e mais próximo o capão da mata ciliar, maior sua diversidade. Foram amostradas seis parcelas de 30 cm² em nove capões onde a serrapilheira e o solo foram coletados, acondicionados em sacos plásticos e posteriormente triados. Houve relação entre a composição da comunidade de artrópodes em relação à distância e o tamanho indicando que o pulso de inundação do último ano afetou de forma significativa a comunidade de artrópodes de solo em capões. O acompanhamento dos processos de recolonização dos capões é sugerido.Palavras-Chave: Artrópodes de solo; Fragmentação; Metacomunidade; Serrapilheira. Capons as Island for Arthropods in PantanalAbstract. The configuration of habitat is one of the factors that influence the distribution of organisms. The Pantanal by presenting mosaic natural formations fit to test such claims. The present study aimed to evaluate the distance and size of riparian capons affect the community composition of arthropods tested the hypothesis that the higher and closer to the capon of riparian vegetation, the greater its diversity. We sampled six plots of 30 cm² in nine capons where the leaf-litter and soil were collected, placed in plastic bags and later sorted. There was a relationship between the composition of arthropod community in relation to distance and size indicating that the flood pulse of the last year significantly affected the community of soil arthropods in geldings. The monitoring of the processes of recolonization of the capons is suggested.
