“…This could be a reason for the lower cross-taxon correlations in b diversity, which is contrary to results in recent publications (Su et al 2004;Kessler et al 2009). A pattern that seems to be consistent across all taxa is that b diversity contributes in a large proportion to gamma diversity (Bermúdez-Rivas unpublished data), a pattern that have been found for spiders and predatory ants (ArcilaCardona et al 2008;Cabra-García et al 2010). Our results suggest that distance between sampling patches (Table 4) explain a very low percentage (0.006-6.760%) of the variation of b diversity across the sampling patches.…”

In this study a and b diversity patterns of five leaf litter arthropod groups (ants, predatory ants, oribatid mites, spiders and other arachnids) were described and compared in 39 sampling patches of a transformed landscape in southwestern Colombia, that represented five vegetation types: secondary forest, riparian forest, giant bamboo forest, pasture and sugarcane crop. It was also assessed whether some taxa could be used as diversity surrogates. A total of 6,765 individuals grouped in 290 morphospecies were collected. Species richness in all groups was lower in highly transformed vegetation types (pasture, sugarcane crop) than in native ones (forests). In contrast, there were no clear tendencies of b diversity among vegetation types. Considering sampling patches, 0.1-42% of the variation in a diversity of one taxonomic group could be explained from the a diversity of another, and 0.2-33% of the variation of b diversity of a given taxon was explained by that in other groups. Contrary to recent findings, we concluded that patterns of a diversity are more congruent than patterns of b diversity. This fact could be attributed to a sampling effect that promotes congruence in a diversity and to a lack of a clear regional ecological gradient that could promote congruent patterns of b diversity. We did Electronic supplementary material The online version of this article (not find evidence for an ideal diversity surrogate although diversity patterns of predatory ants had the greatest congruencies. These results support earlier multi-taxon evaluations in that conservation planning should not be based on only one leaf litter arthropod group.

“…complexity of vegetation) is the most relevant mechanism to explain the community structure (Soininen et al 2007;Losos et al 2010;Silva et al 2010). Habitats with low heterogeneity have low diversity of spiders (Greenstone 1984;Cabra-Garcı´a et al 2010). Cunha et al (2012) showed that the structure of habitats plays an important role to explain the differences in spider community composition.…”

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 characteristics of spider biodiversity in ponds with different habitat structures, by examining patterns across habitats of ponds with different vegetation levels. Sampling took place in four occasions over a year. We compared spider abundance, species richness and composition among ponds including distinct vegetation variables, related to life form, type of leaves, coverage and height. Overall 1174 individuals (194 adults) of 11 families and 37 morphospecies were sampled. We found mostly expected differences in the manner that communities were structured between different habitats. Thus, higher variability of abundance was explained for higher habitat structure of ponds. We also found differences in species composition between ponds with low emergent vegetation and higher habitat structures. Additionaly, spiders were consistently structured more by turnover than nestedness components, with a greater beta diversity of web‐builders. Our results suggest varying levels of habitat structures and species substitution shape pond spider communities, depending on habitat heterogeneity and spider guild. Those findings demonstrate the clear role of spatial habitat structure, with more spider species preferring to build webs or actively hunt at vegetated environments on ponds.

“…Moreover, recent studies have shown that diversity patterns across spatial scales are not only taxon specific (i.e. mobile vs. sessile organism), but also dependent on the diversity measured (Ribeiro et al 2008;Garcia et al 2010;Flohre et al 2011). For dung beetles a high interspecific competition for dung resources could be expected (Hanski & Cambefort 1991), which may reduce diversity at the scale of the dung patch.…”

“…For example, Wagner et al (2000) used additive partitioning and concluded that β diversity among land-use types is more critical than β diversity between patches of the same land-use type in generating plant species richness in agricultural landscapes. Additive partitioning has been applied to several taxa, such as vegetation associations (Wagner et al 2000), birds (Fleishman et al 2003), beetles (Gering et al 2003), moths (Summerville & Crist 2005), and aquatic macroinvertebrate assemblages (Stendera & Johnson 2005), and spiders (Garcia et al 2010). However, the contribution of α and β diversity to regional diversity across a range of spatial scales remain unclear (Loreau 2000;.…”

The importance of spatial scale has been acknowledged as one of determining factors of species diversity in local and regional diversity. The aim of this study was to evaluate contribution of alpha () and beta () diversity across land-use type to gamma () diversity at the margins of tropical forest in Central Sulawesi using dung beetles (Coleoptera: Scarabaeidae) as a focal group. Baited pitfall traps set in four land-use types ranging from natural forest through cacao agroforestry systems to open areas during two years of sampling (2009 and 2012). A total of 28 dung beetle species belonging to four genera were captured during the study period. The results showed that contribution of  diversity was higher than that of  diversity of dung beetles. Each land-use type contributed about 56.5 to 62.5% of the total species richness ( diversity). The similar pattern of biodiversity between each spatial scale and during the two sampling years emphasized the large contribution of each land-use type to maintaining a high portion of the regional species richness. It suggests the importance of managing other land-use types, such as secondary forest and agroforestry as well as protecting the remaining natural forests
