“…Among the Amazon plant species that depend on bees, Bertholletia excelsa HBK ( Cavalcante et al 2018 ), which is popularly known as the Brazil nut tree, is noteworthy, because its nuts present high nutritional and economic value ( Kainer et al 2018 ). Bee pollinators include two species of primitively social Bombus Latreille, 1802 (Hymenoptera: Apidae) and 18 species of solitary bees.…”

Edible fruit plants of tropical forests are important for the subsistence of traditional communities. Understanding the most important pollinators related to fruit and seed production of these plants is a necessary step to protect their pollination service and assure the food security of these communities. However, there are many important knowledge gaps related to floral biology and pollination in megadiverse tropical rainforests, such as the Amazon Forest, due mainly to the high number of plant species. Our study aims to indicate the main pollinators of edible plants (mainly fruits) of the Amazon forest. For this, we adopted a threefold strategy: we built a list of edible plant species, determined the pollination syndrome of each species, and performed a review on the scientific literature searching for their pollinator/visitors. The list of plant species was determined from two specialized publications on Amazon fruit plants, totaling 188 species. The pollination syndrome was determined for 161 species. The syndromes most frequently found among the analyzed species were melittophily (bee pollination), which was found in 101 of the analyzed plant species (54%) and cantharophily (beetle pollination; 26 species; 14%). We also found 238 pollinator/visitor taxa quoted for 52 (28%) plant species in previous publications, with 124 taxa belonging to Apidae family (bees; 52%), mainly from Meliponini tribe (58 taxa; 47%). Knowledge about pollinators is an important step to help on preserving their ecosystem services and maintaining the productivity of fruit trees in the Amazon.

“…The global deficit of information on interactions has been previously emphasized ( Hortal et al, 2015 ) and considering the Brazilian Amazon, few studies have evaluated interactions. Some studies analyzed plant species of economic interest pollinated by bees ( Cavalcante et al, 2018 ; Krug et al, 2018 ; Beyerlein et al, 2019 ) or by complex systems involving multiple insects ( Dattilo et al, 2012 ; Campbell et al, 2018 ). A small additional amount of data is available on interactions between plants and pollinators in the region, including bees ( Moura et al, 2011 ; Novais and Absy, 2013 ; Ferreira and Absy, 2017 ; Oliveira et al, 2017 ; Milet-Pinheiro et al, 2018 ), beetles ( Seymour and Matthews, 2006 ; Gottsberger and Webber, 2018 ), moths ( Cruz-Neto et al, 2011 ), wasps ( Nazareno et al, 2007 ), birds ( Vicentini and Fischer, 1999 ), and bats ( Gribel et al, 1999 ).…”

Flora of Ferruginous Outcrops Under Climate Change: A Study in the Cangas of Carajás (Eastern Amazon)

Climate change has impacted biodiversity, affecting species and altering their geographical distribution. Besides understanding the impact in the species, it has been advocated that answering if different traits will be differently impacted could allow refined predictions of how climate change will jeopardize biodiversity. Our aim was to evaluate if climate change will potentially impact plant species differently, considering their traits. We evaluated 608 plant species that occur in the naturally open areas of ferruginous outcrops (namely, cangas) in the National Forest of Carajás (Eastern Amazon). Firstly, we estimated the effects of climate change on each species using species distribution modeling, and analyzed this impact in the set containing all species. Secondly, we classified plant species considering the following traits: (i) pollination syndromes (melittophily, phalaenophily, psychophily, cantharophily, entomophily, ornithophily, chiropterophily, anemophily); (ii) habit (tree, shrub, herb, liana, parasite); and (iii) the main habitat of occurrence (open areas and forests). Thirdly, we investigated if the effects of climate change could be significantly more intense considering all the different traits quoted. Our results showed that most plant species will potentially face reduction of suitable habitats under future climate and the scenarios showed that 42% of them may not find suitable areas in the cangas of Carajás. We found no significant difference within each analyzed trait, considering the potential impact of climate change. The most climatically suitable areas (i.e., areas with high probability of species occurrence in the future) are those in the southwest of the study area. These areas can be considered as priority areas for species protection against climate change.

Aim Climate change and deforestation will redistribute biodiversity in the next century. Species‐specific differences in the response to these stressors will lead to distribution decoupling of interacting species. However, consequences for ecosystem services are poorly known. Here, we assess the potential effects of future distribution mismatch on a key ecosystem service mediated by seed dispersal and pollination interactions: the sustainable exploitation of Brazil nuts. Location The Amazon. Major taxa studied Woody plants, medium‐sized mammals, and insects. Time period Present day, end of the 21st century. Methods Combining ecological niche models to simulations of tree cover loss and dispersal constraints, we compare the forecasted distribution of the plant to that of its interacting fauna of pollinators and seed dispersers. Results Our projections indicate that climate change itself could have no or even slightly positive effects on the distribution of the Brazil nut tree, expected to increase by up to 6% by the year 2090. However, the pollinators of this tree were forecasted lose nearly 50% of their suitable distribution in the future, leading to an almost 80% reduction in co‐occurrence potential. In addition, local pollinator richness was predicted to diminish by 20%, with likely consequences for pollination redundancy and resilience to subsequent environment changes. Although range contractions were also forecasted for some seed dispersers in the future, the overall patterns of potential co‐occurrence between the Brazil nut tree and seed dispersers, as well as local richness of seed dispersers. were mostly unabated. Main conclusions The forecasted declines in pollinator diversity may reduce ecosystem functional redundancy and threaten the long‐term resilience of the services provided by Brazil nut trees. Such pervasive and indirect effects of climate change, often neglected and unaccounted for in most conservation assessments, may have cascading effects upon into economies and human well‐being worldwide.
