“…Arthropod abundance and functional diversity appear to be recovering more quickly than community composition, a trend consistent with other recent tropical secondary forest studies (Ottermanns et al 2011;Curran et al 2014). Tropical forest arthropod diversity measures are partly based on assumed specializations with plant species (e.g., Erwin 1982), and the greater tree species diversity in primary forests likely sustains higher levels of arthropod diversity (May 1988;Novotny and Basset 2005;Novotny et al 2006).…”

Soil and litter arthropods represent a large proportion of tropical biodiversity and perform important ecosystem functions, but little is known about the efficacy of different tropical forest restoration strategies in facilitating their recovery in degraded habitats. We sampled arthropods in four 7‐ to 8‐year‐old restoration treatments and in nearby reference forests. Sampling was conducted during the wet and dry seasons using extractions from litter and pitfall samples. Restoration treatments were replicated in 50 × 50‐m plots in four former pasture sites in southern Costa Rica: plantation – trees planted throughout the plot; applied nucleation/islands – trees planted in patches of different sizes; and natural regeneration – no tree planting. Arthropod abundance, measures of richness and diversity, and a number of functional groups were greater in the island treatment than in natural regeneration or plantation treatments and, in many cases, were similar to reference forest. Litter and pitfall morphospecies and functional group composition in all three restoration treatments were significantly different than reference sites, but island and plantation treatments showed more recovery than natural regeneration. Abundance and functional group diversity showed a much greater degree of recovery than community composition. Synthesis and applications: The less resource‐intensive restoration strategy of planting tree islands was more effective than tree plantations in restoring arthropod abundance, richness, and functional diversity. None of the restoration strategies, however, resulted in similar community composition as reference forest after 8 years of recovery, highlighting the slow rate of recovery of arthropod communities after disturbance, and underscoring the importance of conservation of remnant forests in fragmented landscapes.

“…The variability within younger and older succession stages, respectively, originates in our opinion from the heterogeneity of biogeochemical, vegetational and microclimatic conditions. This assumption is supported by the results of Ottermanns et al (2011), who showed a strong influence of vegetational (structural) and microclimatic conditions on beetles in the study region. During further forest succession the variance in biotic and abiotic habitat parameters within the stages seems to decrease (see also Raub et al 2014b).…”

In the Atlantic Forest in Brazil, where no more primary forests exist, the value of secondary forests for biodiversity conservation is becoming more and more important. We studied the spiders in a relatively wellpreserved region of the Mata Atlântica, where the matrix of the landscape is still forest. We addressed the contribution of different spatial levels including forest stages to total diversity and analyzed the patterns by additive partitioning of beta diversity on genus and morphospecies level and for different sampling methods. Beta diversity was strongly based on turnover, not on gain/loss. All spatial levels (sample, stage, area, locality) contributed more to beta diversity than expected, without stronger influence of stage. Patterns were consistent for both identification levels and all methods. We conclude that in this landscape the protection of large areas encompassing all forest stages, without special attention to old-growth, is the best way to conserve the regional species richness.

“…Although their use for bioindication under the conditions assessed in this study still requires closer evaluation, our results support this potential application. Ottermanns et al (2011) found a correlation between litter mass and Coleoptera species density, and Kataguiri (2006) observed an increase in the abundance of oribatid mites when evaluating successional gradients in Atlantic forests. However, these findings were not corroborated in this study, although small increases in the occurrences of some Coleoptera families, such as Staphylinidae, were observed.…”

Litter and soil arthropod colonization in reforested semi‐deciduous seasonal Atlantic forests

The recovery of soil ecological processes during the restoration of tropical forests is greatly influenced by arthropods that live in the litter and soil. However, these communities present complex dynamics, and their colonization patterns are not well understood. In this study, we examined the response patterns of litter and soil arthropods to the ecosystem regeneration process by assessing reforestation sites from two regions of São Paulo State, Brazil, and we compared the data obtained from these sites with data from mature forests. We assessed the arthropod communities using similarity indices and high‐level taxa abundance, with the level of forest succession and the locations of the restoration areas as factors. Forest succession correlated with the species composition as communities from the reforestation sites gradually became more similar to communities from the mature forests, while their quantitative patterns were minimally related. Forest maturation positively affected the richness of the litter community and the abundance of some minor groups, such as Protura, Diplura, and Symphyla. The region influenced the species composition but did not influence the manner in which the communities changed during the maturation process. We also found a convergent soil colonization pattern as arthropod communities from different sites became more similar during forest succession. This finding is consistent with both empirical data and theoretical predictions from the specialized literature, although the subject has been poorly explored until now. We conclude that reforestation allows the colonization of soil and litter fauna in a biased manner.
