Abstract: ABSTRACT. Conservation of biodiversity in agroecosystems is an urgent need, and a suitable approach to maximize animal biodiversity and their services is the restoration of habitat heterogeneity. Here we investigated the value of increasing litter complexity in tree plantations of exotic pine for ground spiders. We hypothesized that increasing the litter complexity of these systems, as it would be the case in ecologically designed plantations, would increase spider aggregations. We performed a small-scale litt… Show more

“…Comparable to our results, Kosulic et al (2016) found higher species numbers but lower functional diversity of spider assemblages in oak forests with an open canopy compared to oak forests with dense canopy (see also Ziesche & Roth, 2008). High habitat complexity in the ground stratum caused by the herb layer, tree stumps, branches, open soil, moss and leaf litter might provide a higher number of niches that could allow closely related species to coexist (Podgaiski & Rodrigues, 2017). Moreover, open forests are characterized by higher, small‐scale variation in soil and litter moisture (Stein & Kreft, 2015) due to the loss of mature trees.…”

“…On a scale relevant for spiders, habitat structure is determined mainly by vegetation (or sometimes even by a single plant), which provides spiders with a decent level of humidity, shelter, abundance of prey, and sufficient structures for building webs [22][23]43]. Structurally more complex habitat increases the number of spiders, spider species, and species diversity [19,22,44]. Moreover, field experiments showed that individuals of spiders are larger in such habitats.…”

“…The habitat diversity paradigm generally suggests that more complex habitats provide more niches for more species. For example, Podgaiski and Rodrigues (2017) reported increased abundance and species richness of spiders after habitat diversity was experimentally enhanced by increased litter diversity in pine forests in Brazil. Reviews concluded that there is good evidence that habitat diversity positively influences the number of species in both terrestrial (Tews et al 2004) and aquatic ecosystems (Hasselquist et al 2018).…”
