“…In Spain, Baz & Garcia-Boyero (1995) found forest area within a 1 km radius to be a positive predictor of butterfly diversity in forest fragments. Most recently, in Brazil, Campbell et al (2022) found forest cover within 400 m to best explain the richness of flower-visiting insects in açaí palm (Euterpe oleracea Mart.) plantations.…”

“…Throughout the tropics, for example, eusocial stingless bees depend largely, although not entirely, on trees for nesting (Salmah et al, 1990;Roubik, 1983Roubik, , 1989. This group is particularly sensitive to the amount of forest cover (Brosi, 2009a;Salmah et al, 1990;Brown & Albrecht, 2001;Gutiérrez-Chac on et al, 2018;Ricketts, 2004;Heard & Exley, 1994;Klein et al, 2003;Campbell et al, 2022) to the point that they are largely extirpated from the most extensively deforested areas. In Brazil, for example, Kerr et al (1999) estimated that 95% of stingless bee species had been lost from the São Paulo area where only 6% of the original forest cover remains.…”

Forests are critically important to global pollinator diversity and enhance pollination in adjacent crops

Although the importance of natural habitats to pollinator diversity is widely recognized, the value of forests to pollinating insects has been largely overlooked in many parts of the world. In this review, we (i) establish the importance of forests to global pollinator diversity, (ii) explore the relationship between forest cover and pollinator diversity in mixed‐use landscapes, and (iii) highlight the contributions of forest‐associated pollinators to pollination in adjacent crops. The literature shows unambiguously that native forests support a large number of forest‐dependent species and are thus critically important to global pollinator diversity. Many pollinator taxa require or benefit greatly from resources that are restricted to forests, such as floral resources provided by forest plants (including wind‐pollinated trees), dead wood for nesting, tree resins, and various non‐floral sugar sources (e.g. honeydew). Although landscape‐scale studies generally support the conclusion that forests enhance pollinator diversity, findings are often complicated by spatial scale, focal taxa, landscape context, temporal context, forest type, disturbance history, and external stressors. While some forest loss can be beneficial to pollinators by enhancing habitat complementarity, too much can result in the near‐elimination of forest‐associated species. There is strong evidence from studies of multiple crop types that forest cover can substantially increase yields in adjacent habitats, at least within the foraging ranges of the pollinators involved. The literature also suggests that forests may have enhanced importance to pollinators in the future given their role in mitigating the negative effects of pesticides and climate change. Many questions remain about the amount and configuration of forest cover required to promote the diversity of forest‐associated pollinators and their services within forests and in neighbouring habitats. However, it is clear from the current body of knowledge that any effort to preserve native woody habitats, including the protection of individual trees, will benefit pollinating insects and help maintain the critical services they provide.

“…From the ecological point of view, knowing of taxonomic and functional diversity of bees is essential for better understand ecosystems' functioning in order to ensure biodiversity conservation, as well as food security and human subsistence (Borges et al 2020, Campbell et al 2022. Studies focused on conserving bees require taxonomic and biological knowledge to determine these pollinators' important species in native forests in different regions (Thakur et al 2012).…”

The bee fauna (Hymenoptera, Apoidea) in Cerrado and Cerrado-Amazon Rainforest transition sites in Tocantins state, Northern Region of Brazil

et al. 2022

Two sites located in Tocantins State, Brazil, were selected for the bee’s community survey. One of them was mostly covered by Cerrado vegetation and the other one is located in the Cerrado-Amazon Rainforest ecotone. Five expeditions were performed in each site throughout a 12-month period, between 2019 and 2020. The total of 771 bee specimens were collected and distributed into four families. Apidae presented the greatest species abundance and richness, it was followed by Halictidae, Megachilidae and Andrenidae, respectively. Trigona pallens (Fabricius) (Apidae) was the species presenting the greatest abundance in both sites, it totaled 118 specimens, which corresponded to 26.9% of the total abundance of individuals belonging to tribe Meliponini. In general, the community presented several species with few individuals and few species with many individuals. Bee collections were performed by using three different methodologies, among them one finds sampling based on the entomological net method, which allowed collecting the largest number of both individuals and species in comparison to the other used methods. Based on the frequency and abundance classes, only few species were classified as very frequent (VF) and very abundant (VA) in both sites based on the frequency and abundance classes. Most species were constant (W) in both regions, and there was a small number of dominant species (D); moreover, more than 70% of the sampled species were considered accidental (Z). According to the present study, either Cerrado or Cerrado-Amazon Rainforest studied sites presented higher species richness than other sites in these biomes sampled in Brazil.

“…Se estima que reducir la deforestación ha prevenido hasta USD 1 billón de pérdidas agrícolas anuales en el sur de la Amazonia Brasileña 11 . Mantener la biodiversidad también es esencial, como una ética imperativa, un prerrequisito para mantener la resiliencia Amazónica, y para la protección de los servicios ecosistémicos, tal como la polinización 12,13 . Ayuda a garantizar la seguridad alimentaria para poblaciones rurales, urbanas, y periurbanas, pueblos indígenas, y comunidades locales.…”

Territorios indígenas (ITs, en sus siglas en inglés) en la Amazonia protegen aproximadamente 24,GtC sobre el suelo, funcionan como barreras significativas contra la deforestación y la degradación del bosque, y sirven como una defensa importante contra el cambio climático. Los ITs demarcados tienen significativamente menos deforestación en comparación con tierras no reconocidas, demostrando la importancia de demarcar ITs para proteger los sustentos y la cultura de los indígenas Amazónicos y para conservar sus bosques y ríos.
