“…2). This aligns with previous studies showing that non-native plantations provide habitat for a small subset of tropical forest species (Barlow et al 2007;Lees et al 2015;Millan et al 2015) without acting as a species source (Hawes et al 2008). Pastures, in contrast, not only provide a habitat for different species (Moura et al 2013;Lees et al 2015), but also allow them to spillover into native forest, as shown by the increase in the richness of disturbance-tolerant species in fragments (Figs.…”

“…One of the important characteristics of plantations is their greater structural complexity compared with pastures. They are often structurally similar to native forest (Prevedello & Vieira 2010), but variation in structural complexity of plantations is also important because those with higher complexity (e.g., multiple vegetation strata) generally contain higher bird species richness and abundance (Nájera & Simonetti 2010;Millan et al 2015). The plantation sites surveyed in this study often retained understory foliage, a practice that is not universal, but which matches the management practices in other studies that concluded that plantations have some utility for biodiversity (e.g., Barlow et al 2007).…”

“…As with secondary forests (Mayhew et al 2019), the conservation value of plantations largely depends on the maintenance and extent of embedded native forest patches. Nonetheless, although intensive research has been conducted on the effects of management on biodiversity within plantations themselves (Nájera & Simonetti 2010;Millan et al 2015), little is known about how plantation management and harvesting practices affect adjacent native forests. We recommend that future research investigates how management practices mediate effects of plantations on biodiversity in adjacent forest fragments because doing so may provide a key insight into practical conservation solutions for human modified tropical forest landscapes.…”

Habitat loss, fragmentation, and degradation have pervasive detrimental effects on tropical forest biodiversity, but the role of the surrounding land use (i.e., matrix) in determining the severity of these impacts remains poorly understood. We surveyed bird species across an interior‐edge‐matrix gradient to assess the effects of matrix type on biodiversity at 49 different sites with varying levels of landscape fragmentation in the Brazilian Atlantic Forest—a highly threatened biodiversity hotspot. Both area and edge effects were more pronounced in forest patches bordering pasture matrix, whereas patches bordering Eucalyptus plantation maintained compositionally similar bird communities between the edge and the interior and exhibited reduced effects of patch size. These results suggest the type of matrix in which forest fragments are situated can explain a substantial amount of the widely reported variability in biodiversity responses to forest loss and fragmentation.

“…) and birds (Millan et al . ), it is important to clarify that these findings may not necessarily apply to all eucalyptus plantations. In our scenario, reserves are primarily patches of native forests, occasionally separated by eucalyptus that may facilitate ocelot movement between native forest patches.…”

Factors influencing ocelot occupancy in Brazilian Atlantic Forest reserves

Over 80% of Atlantic Forest remnants are <50 ha and protected areas are embedded in a matrix dominated by human activities, undermining the long-term persistence of carnivores. The ocelot (Leopardus pardalis) is an opportunistic species, but little is known about its tolerance to habitat alterations and the influence of other species on its occupancy in Atlantic Forest remnants. We used camera traps to assess ocelot occupancy in protected areas of Atlantic Forest in southeastern Brazil. We found a positive correlation between the occupancy of ocelots and top predators (jaguars, Panthera onca, and pumas, Puma concolor), and a weaker negative effect between the number of domestic dogs (Canis familiaris) detected and ocelot occupancy. Ocelot detection was higher at sites with more eucalyptus, suggesting that ocelots frequently use these areas. Better-protected areas surrounded by permeable matrices may be critical to the persistence of ocelots in the fragmented Atlantic Forest.Abstract in Portuguese is available with online material.

“…Local habitat quality at our sampling sites is likely one of the main factors governing differences in TR between pasture and eucalyptus. The suitability of tree plantations in sustaining species-rich bird assemblages is often higher if they contain native regenerating woody plants (Deconchat et al 2009, Najera and Simonetti 2010, Lopes et al 2015, Millan et al 2015. However, most eucalyptus sites in our study were commercial tree plantations where native trees and shrubs were either non-existent or rare.…”

Matrix type and landscape attributes modulate avian taxonomic and functional spillover across habitat boundaries in the Brazilian Atlantic Forest

Land use intensification drives biodiversity loss worldwide. In heterogeneous landscape mosaics, both overall forest area and anthropogenic matrix structure induce changes in biological communities in primary habitat remnants. However, community changes via cross‐habitat spillover processes along forest–matrix interfaces remain poorly understood. Moreover, information on how landscape attributes affect spillover processes across habitat boundaries are embryonic. Here, we quantify avian α‐ and β‐diversity (as proxies of spillover rates) across two dominant types of forest–matrix interfaces (forest–pasture and forest–eucalyptus plantation) within the Atlantic Forest biodiversity hotspot in southeast Brazil. We also assess the effects of anthropogenic matrix type and landscape attributes (forest cover, edge density and land‐use diversity) on bird taxonomic and functional β‐diversity across forest–matrix boundaries. Alpha taxonomic richness was higher in forest edges than within both matrix types, but between matrix types, it was higher in pastures than in eucalyptus plantations. Although significantly higher in forests edges than in the adjacent eucalyptus, bird functional richness did not differ between forest edges and adjacent pastures. Community changes (β‐diversity) related to species and functional replacements (turnover component) were higher across forest–pasture boundaries, whereas changes related to species and functional loss (nested component) were higher across forest–eucalyptus boundaries. Forest edges adjacent to eucalyptus had significant higher species and functional replacements than forest edges adjacent to pastures. Forest cover negatively influenced functional β‐diversity across both forest–pasture and forest–eucalyptus interfaces. We show the importance of matrix type and the structure of surrounding landscapes (mainly forest cover) on rates of bird assemblage spillover across forest‐matrix boundaries, which has profound implications to biological fluxes, ecosystem functioning and land‐use management in human‐modified landscapes.
