“…Biologically, our results reveal that, for managed Eucalyptus plantation, 28 years of abandonment were not enough for the ant communities to recover the characteristics of those found in native forests. Studies with others organism, such as dung beetles 54 , 56 , lizards 57 , or arachnids 58 , also suggest that communities in native forest differ not just from plantations forests, but also from secondary or restored forests, demonstrating the uniqueness of primary forests and the importance of maintaining these habitats.…”

Despite its negative impacts on the environment and biodiversity, tree plantations can contribute to biodiversity conservation in fragmented landscapes, as they harbor many native species. In this study, we investigated the impact of Eucalyptus plantations on the taxonomic and functional diversity of ant communities, comparing ant communities sampled in managed and unmanaged (abandoned for 28 years) Eucalyptus plantations, and native Atlantic rain forests. Eucalyptus plantations, both managed and unmanaged, reduced the functional diversity and increased the similarity between ant communities leading to functional homogenization. While communities in managed plantations had the lowest values of both taxonomic and functional ant diversities, ant communities from unmanaged plantations had similar values of species richness, functional redundancy and Rao’s Q compared to ant communities from forest patches (although functional richness was lower). In addition, communities in unmanaged Eucalyptus plantations were taxonomically and functionally more similar to communities located in managed plantations, indicating that Eucalyptus plantations have a severe long-term impact on ant communities. These results indicate that natural regeneration may mitigate the impact of Eucalyptus management, particularly regarding the functional structure of the community (α diversity), although it does not attenuate the effects of long term homogenization in community composition (β diversity).

“…In the MTZ, other studies have also found that grazing areas have a positive effect on dung beetle abundance and diversity at high elevations and in dry environments, specifically in pine–oak forest and semiarid scrubland (Barragán et al, 2014) and JF (Ortega-Martínez, Moreno & Escobar, 2016) of the Sierra Madre Oriental province. Similarly, dung beetle abundance is higher in human-created pastures than in native savannah-like vegetation in the Cerrado ecosystem in Brazil, and the influence of the edge is evident only for abundance when landscape matrix is pastureland (Martello et al, 2016). Thus, the presence of cattle may have a positive effect on dung beetle abundance, probably due to higher resource availability (dung), but very intensive grazing may reduce their diversity (Hutton & Giller, 2003).…”

Edge effects alter insect biodiversity in several ways. However, we still have a limited understanding on simultaneous responses of ecological populations and assemblages to ecotones, especially in human modified landscapes. We analyze edge effects on dung beetle populations and assemblages between livestock pastures and native temperate forests (Juniperus and pine-oak forests (POFs)) to describe how species abundances and assemblage parameters respond to edge effects through gradients in forest-pasture ecotones. In Juniperus forest 13 species avoided the ecotones: six species showed greater abundance in forest interior and seven in pasturelands, while the other two species had a neutral response to the edge. In a different way, in POF we found five species avoiding the edge (four with greater abundance in pastures and only one in forest), two species had a neutral response, and two showed a unimodal pattern of abundance near to the edge. At the assemblage level edge effects are masked, as species richness, diversity, functional richness, functional evenness, and compositional incidence dissimilarity did not vary along forest-pasture ecotones. However, total abundance and functional divergence showed higher values in pastures in one of the two sampling localities. Also, assemblage similarity based on species’ abundance showed a peak near to the edge in POF. We propose that conservation efforts in human-managed landscapes should focus on mitigating current and delayed edge effects. Ecotone management will be crucial in livestock dominated landscapes to conserve regional biodiversity and the environmental services carried out by dung beetles.

“…In contrast to the potential of mandatory forest restoration to provide both watershed services and biodiversity conservation, the Native Vegetation Protection Law of 2012, which replaced the 1965 Forest Code, strongly reduced the minimum width of riparian corridors that must be restored along streams and around springs in Brazil (Soares-Filho et al., 2014). The restoration of thin corridors, which are more susceptible to edge effects (Martello, Andrioli, de Souza, Dodonov, & Ribeiro, 2016; Mendes, Ribeiro, & Galetti, 2015), may provide less functional connectivity of the landscape and thus suboptimal levels of biodiversity conservation services (Brancalion, Garcia, et al., 2016a; Rotta, Viani, & Rosario, 2016). In conclusion, there is great potential for incorporating biodiversity conservation objectives into projects primarily designed and funded for improving the provision of water-related ES, a potential that can be optimized by adopting a landscape ecology perspective in the planning and implementation of ecological restoration efforts.…”

Restoration projects designed to promote one ecosystem service may have synergistic benefits to other services. Therefore, bundling them can be an effective way to maximize the return to the investments in programs of payments for ecosystem services (PES). Here, we investigated the additional gain of restoration actions-which were implemented as part of a PES program to protect a key watershed for water supply-on increasing functional landscape connectivity in the Atlantic Forest region of southeastern Brazil. Using a landscape ecology approach, we estimated the amount of forest cover before (2006) and after (2012) restoration activities by the PES program and changes in structural and functional landscape connectivity for birds with varying gap-crossing capabilities. Forest cover increased from 42.5 to 86.1 ha after the implementation of restoration projects by the PES program. In the simulated scenarios of landscape connectivity, the mean patch size of functionally connected forest increased by 1,034%, 392%, 248%, and 94% for species with gap-crossing capabilities of 0, 20, 40, and 60 m, respectively. Our results highlight the potential for incorporating biodiversity conservation objectives into PES projects primarily designed to enhance water-related ecosystem services.
