“…For Amazonian primates, most species distributions will increase if only the climate is considered, half of them will decrease if rivers are considered as dispersal barriers, and most of them will decrease if climate, barriers and habitat loss are included 36 . A recent study with 12 primate species endemic to the Amazon also addresses that condition, pointing out that four species will lose 90% of their range, increasing to eight species as deforestation is added into the analysis, with about three species losing more than 98% of their distribution 51 . The biotic velocity necessary to follow preferred climate conditions is larger than Amazonian primates' maximum dispersal ability 52 .…”

Global climate changes affect biodiversity and cause species distribution shifts, contractions, and expansions. Climate change and disease are emerging threats to primates, and approximately one-quarter of primates’ ranges have temperatures over historical ones. How will climate changes influence Atlantic Forest primate ranges? We used habitat suitability models and measured potential changes in area and distributions shifts. Climate change expected in 2100 may change the distribution area of Atlantic Forest primates. Fourteen species (74%) are predicted to lose more than 50% of their distribution, and nine species (47%) are predicted to lose more than 75% of their distribution. The balance was negative, indicating a potential future loss, and the strength of the reduction in the distribution is related to the severity of climate change (SSP scenarios). Directional shifts were detected to the south. The projected mean centroid latitudinal shift is ~ 51 km to the south for 2100 SSP5-8.5 scenario. The possibility of dispersal will depend on suitable routes and landscape configuration. Greenhouse gas emissions should be urgently reduced. Our results also emphasize that no more forest loss is acceptable in Atlantic Forest, and restoration, canopy bridges, friendly agroecosystems, and monitoring of infrastructure projects are urgent to enable dealing with climate change.

“…However, by considering herbs, shrubs and small palms, the understory owering species ora is expected to achieve over 20% of all species (see Costa and Magnusson 2002). Unfortunately, there is little information about the Amazon estuarine forest, even for the tree ora, although this unique forest represents the core area of açaí production and intensi cation (Brondízio, 2008) and an ecologically unique component of an area of species endemism considering an immense number of taxa, from insects to primates (Moraes et al, 2020;Silva et al, 2022).…”

The exploitation of non-timber forest products has been proposed as a sustainable way to exploit tropical forests, but such an opportunity remains to examined case-by-case. We examine the impact by the intensification of the açaí palm (Euterpe oleracea) management for fruit production via increments on palm clumps/stems density on the woody plant assemblages (adult and regenerating) in an estuarine forest landscape in the eastern Amazon region, Brazil. Across 30 forest stands açaí clumps density correlated negatively with stem density and taxonomic diversity considering both adult and regenerating woody plant assemblages, but it posed a positive effect on beta diversity via species turnover. Soil fertility and forest stand accessibility played a complementary role. Moreover, açaí clump density affected the abundance of particular woody plant species, including a set of species declining before the 400-açaí clump density threshold imposed by current regulation. Accordingly, açaí clump density influenced the taxonomic organization of woody plant assemblages at landscape spatial level. Finally, it is worth mention a group of 105 species, which were recorded across the regenerating assemblages but not in the adult assemblages. Among them, a large number of small-statured woody plant species typical from the forest understory (i.e., the shade-tolerant flora) such as those from Miconia, Piper, Bactris, Anonna and Geonoma genus among many. As intensification is still spreading it can be considered a threat to the integrity of the Amazon estuarine forest. It questions the ecological sustainability the current Amazonian “black gold” is produced.

“…The few estimates available report a minimum of 16% of tree species flora belonging to this ecological group in the Amazon region (Assis & Wittmann, 2011); however, by considering herbs, shrubs and small palms, the understory flowering species flora is expected to achieve over 20% of all species (see Costa & Magnusson, 2002). Unfortunately, there is little information about the Amazon estuarine forest, even for the tree flora, although this unique forest represents the core area of açaí production and intensification (Brondízio, 2008) and an ecologically unique component of an area of species endemism considering an immense number of taxa, from insects to primates (Moraes et al, 2020; Silva et al, 2022).…”
