“…The region is known as an important endemism area for several taxonomic groups, and has been considered one of the most important in the Atlantic Forest (Franke et al, 2005;Nemésio, 2013a). The orchid bee fauna of the Central Atlantic Forest Corridor was studied in the southern portion of Bahia (Nemésio, 2013a;Nemésio, 2013b;Nemésio, 2013c;Nemésio, 2014) and in a region near to our study area (Rosa et al, 2015). However, large variations have been observed in orchid bee communities, even in neighboring regions, which could be related to habitat heterogeneity (Tonhasca et al, 2002b).…”

To investigate species composition, diversity, richness, and monthly abundance of orchid bees in different types of dense rainforest, placed in different altitudes, the orchid bees were collected for 11 months in three vegetation types: dense montane ombrophilous forest (DMOF), dense submontane ombrophilous forest (DSOF, with two sites points), and dense lowland ombrophilous forest (DLOF). Were collected 1,945 males of 20 species using aromatic traps. The DMOF showed the highest species richness (19), and diversity (H’ = 2.42) , whereas the DSOF_1 showed the highest abundance (775). Euglossa cordata (Linnaeus) was the most abundant species in three areas, and Euglossa ignita Smith was the most abundant species in the DSOF_2 . Abiotic factors were correlated with some community parameters. Our study reveals the importance of preserving different phytophysiognomies within the same biome to conserve orchid bees.

“…According to our models, the region where the environmental suitability for E. marianae has been highly stable through the last 21 000 years and will remain so in future scenarios is located in southern Bahia and northern Espírito Santo. There are large remnants (>10 000 ha) of Atlantic Forest in this area, all well sampled and with relatively abundant populations of E. marianae (Bonilla‐Gómez, ; Nemésio, , ,b,c,d, ). Deforestation is the main current problem in the region.…”

Effects of climate change and habitat loss on a forest‐dependent bee species in a tropical fragmented landscape

1. Climate change and deforestation are suggested to be the main drivers of decline in pollinators. Forest-dependent species are expected to be the most affected and Euglossa marianae Nem esio (Hymenoptera: Apidae), an endemic species of the highly fragmented Brazilian Atlantic Forest (AF), is believed to be declining as a consequence of human impact.2. Over the last 17 years, we carried out field surveys to unveil its distribution, allowing us to investigate the potential effects of global climate change on this species, from the last glacial maximum into the future, using species distribution models. Our main goals were to: (i) identify populations potentially under risk of extinction given future climate change; (ii) quantify the amount of climatically suitable and climatically stable areas for E. marianae within AF; (iii) evaluate the area that are available as natural habitat and under legal protection, in an attempt to indicate priority areas to preserve this species.3. The most stable areas for maintaining populations of E. marianae were located in southern Bahia and northern Esp ırito Santo states, a region severely affected by deforestation and with several protected areas. Climate change per se does not seem to be the major problem for E. marianae. It may constitute an indirect problem given the limited dispersal abilities of this species, however. 4. Climatically suitable areas will probably increase southwards in the future, but the extreme fragmentation of AF adds great uncertainty as to whether the species will disperse southwards, to regions such as the 'Serra do Mar' in northeastern São Paulo.

“…Many species of orchid bees occur and nest in urban landscapes (Storti et al 2013). Relatively small forest fragments, such as public parks, in urban areas can act as dispersion corridors and increase habitat connectivity for bee assemblages (Nemésio and Silveira 2007;Storck-Tonon et al 2013;Storti et al 2013;Nemésio 2014).…”

Orchid bees in riparian and terra-firme forest fragments in an urban matrix in southwestern Brazilian Amazonia

Riparian forests are important ecosystems that support an enormous biodiversity in Brazil. Despite being protected under Brazilian legislation, these forests suffer great impact from the fragmentation of habitats. Orchid bees are a key group of pollinators in the Neotropical region, yet few data are available on the assamblage structure of these bees in riparian forests. We evaluated the role of fragments of riparian and terra-firme forest on the conservation and maintenance of orchid bees in an urban landscape in the southwestern Amazon basin. Specifically, we evaluated whether bee assemblages in riparian and terra-firme forests differed significantly in abundance, species richness and composition. We also evaluated whether species richness and abundance of bees vary with the size of the forest fragment. Male bees were attracted using odoriferous baits and collected with entomological nets in 10 forest fragments. There was no significant difference between riparian and terra-firme fragments in species abundance, richness and composition, but there was a positive correlation between fragment size and species richness and abundance. Our results suggest that, in an urban landscape, the remaining riparian and terra-firme forest fragments still could maintain 62.7% of the orchid bee species known to occur in the region, reinforcing the conservation value of these forest remnants. Our findings indicate that these fragments provide a potentially important habitat for the maintenance of local bee populations in the landscape.
