Fruit removal is a key component of the seed dispersal process with direct consequences for plant recruitment. Anthropogenic disturbances might affect removal rates by changing frugivore diversity and their behavior. Here, we investigated the effects of local forest structure and landscape context on fruit removal of two common pioneer species of Melastomataceae family, Clidemia capitellata and Henriettea succosa in 14 Atlantic forest sites. We evaluated local forest structure, measured as canopy openness and conspecific density, and the amount of forest cover at the landscape scale measured in 2000 m buffer radius. Our results showed that the landscape context was more important than local features to explain fruit removal. The percentage of fruits removed from both species sharply decreases with forest loss and increases again in highly deforested landscapes. We demonstrate changes in fruit removal due to forest loss and suggest that both Melastomataceae species rely on the absence of other plant species, and consequently, in a less competitive environment to increase fruit removal and seed dispersal. Abstract in Portuguese is available with online material.

“…Changes in landscape structure, such as habitat amount, edge effect and heterogeneity, can affect essential ecological processes such as dispersal (Corlett, 2017;Bovo et al, 2018), seed predation (Mendes et al, 2016), and pollination (Hadley and Betts, 2011;Duarte et al, 2018), and consequently compromise population persistence (Santos et al, 2016;Regolin et al, 2017). Landscape changes may also affect population connectivity and genetic diversity in different taxa (e.g., Dixo et al, 2009;Carvalho et al, 2015;Jackson and Fahrig, 2016;Moraes et al, 2018;González-Fernández et al, 2019).…”

“…The area is located in the Atlantic Forest, which is a wide forest complex with high level of endemism and biodiversity. This forest represents 8% of the Brazil's original land cover with spread spots leftover through the coastal area (Bovo et al, 2018;Magnago et al, 2015). The study area is characterized by the following diverse landscapes units according to Dantas (2001): (1) mountainous landscape and escarpment uplands, (2) alkaline intrusion uplands, (3) degraded escarpment uplands and steps in edge of plateau, (4) alignment uplands and structural steps, (5) isolated hills, (6) dissected hills landscape, low hills and high hills, (7) fluvial-marine plains, and (8) fluvial-lake plains (Figure 1).…”

The Brazilian Forest Code implemented in 2012 kept the definition of preservation areas established in the former Forest Code (1965) but changed the delimitation parameters especially for Permanent Preservation Area (PPA) on the top of hills. In Rio de Janeiro, The State Environmental Institute (Inea) established a Resolution in 2014 to guide PPA delimitation in the state. This resolution follows most of the policies implemented by the Brazilian Forest Code of 2012 but defined new parameters for determining the hills bases. This study's goal consists on mapping the PPA on top of hill according to both legal devices and assessing the extension and connectivity of the preservation areas on São João river basin, RJ. Following the Forest Code of 2012, 60 fragments of PPA were delimited, with 553 ha of total area and distributed without any connectivity on higher altitudes. Meanwhile, following Resolution of 2014, 324 fragments of PPA were mapped, totalizing 8,420 ha, situated along the watershed and middles altitudes and enhancing connectivity. We conclude that the alteration of the delimitation parameters has an influence on the extension and connectivity of the PPA on top of hills. Our results suggest the need of deeper evaluations in order to guarantee that methodologies for PPA delimitation on top of hills embodied in legal instruments meet the environment functions clearly established for PPA in the 2012 Brazilian Forest Code.
