Orchid bees are important long-distance pollinators in Neotropical rainforests. Despite their great flight capacity, some species avoid leaving the forest and might be then more vulnerable to the negative effects of habitat fragmentation. Here, we sampled the euglossine fauna from a forest fragment in an urban zone and compared the data to two surveys conducted in the same area 28 and 20 years before. Twelve species were sampled, and the highest values of both abundance and richness were recorded in the present sampling. Species turnover was observed with the resilient species Euglossa cordata and Eulaema nigrita presenting a high increase in number over the years whereas the prevalent species in the former samplings, Euglossa pleosticta , show the highest stable populations. Conversely, the abundance of Euglossa annectans decreased until zero in the last sampling. The studied orchid bee populations had a lower stability value when compared with other euglossine long-term surveys.Our results indicate that even a small forest fragment within an urbanised landscape and subjected to different levels of anthropogenic impacts harbours a diverse euglossine fauna. It is suggested that not only the preservation and maintenance of forest fragments in urban areas but also its restoration after environmental impacts are important procedures to support species-rich wildlife.

“…Of the 14 Atlantic Forest areas included in our analysis, ten [RJ1 (Ramalho et al 2009), PR4 (Mattozo et al 2011), SP3 and SP4 (Rocha-Filho and Garófalo 2013) and SP6 (Boracéia) SP7 (Neblinas), SP8 (Ilhabela) and SP9 (Cantareira) (Cordeiro et al 2013) and BA1 and AL1 (Nemésio 2010(Nemésio , 2011] were carried out in Rainforest (RF) areas and four [SP1 and SP2 (Rebêlo and Garófalo 1997), SP5 (Jesus and Garófalo 2000) and PR5 (Sofia et al 2004)] in Seasonal Semi-Deciduous Forest (SF) areas. Thus, a total of 17 sites (three from the current study and 14 from these nine other studies) related to the three major types of Atlantic Forest vegetation (RF, SF and MF) were analyzed through the DCA.…”

Orchid bee (Hymenoptera: Apidae: Euglossini) assemblages from three different threatened phytophysiognomies of the subtropical Brazilian Atlantic Forest

2014

Euglossine bees were sampled in three different phytophysiognomies [Rainforest (RF), Mixed Forest (MF) and Seasonal Semi-Deciduous Forest (SF)] of Brazilian Atlantic Forest (AF). In this study, euglossine males attracted to eight synthetic scent baits were captured with an entomological net. Results revealed different euglossine bee assemblages associated with three AF ecosystems surveyed. A higher richness (14 spp.) of euglossines was found in the RF, followed by SF (seven spp.) and MF (three spp.) forests. Surprisingly, despite the short distance between MF and SF and that both forest remnants were located in the same studied region and under the same climatic conditions, the species richness detected was lower in MF than in SF. The present study contribute to greater knowledge of euglossine assemblages in remnants of Atlantic Forest areas composed of MF, SF and RF, helping to further understand how the structure of these bee assemblages can vary significantly at the local and/or regional level. In addition, our findings also represent a contribution to the understanding to the orchid bee biogeography.

“…The three most frequent species surveyed in the Itamacaoca Reserve Gallery Forest are commonly found in open and dry Neotropical areas. E. nigrita is generally found in several brazilian ecosystems, from Amazonian areas (Silva & Rebêlo 1999) to Southern Brazil (Sofia et al 2004) and it is one of the fewer euglossine species found in the caatinga, a semi-arid brazilian ecosystem characterized by scrub vegetation and presenting a low and highly seasonal rainfall (Lopes et al 2007). The orchid bee E. cordata is well represented in open, disturbed and dry areas (Silva & Rebêlo 2002), and also was recorded in the caatinga ecosystem, as well as E. securigera (Dressler, 1982) (Lopes et al 2007).…”

The orchid bees are a very important group of pollinators distributed in the Neotropics. Although a lot of studies concerning male euglossine bees have been done in this region, few works have so far been carried out in the Cerrado biome. This manuscript has the main objective to present the orchid bee community from a Gallery Forest in the Northeastern Brazilian Cerrado landscape, taking account the species composition, abundance, seasonality and hourly distribution. Male euglossine bees were collected monthly from October 2007 to May 2009, in the Reserva Florestal da Itamacaoca belonging to the Companhia de Água e Esgoto do Maranhão, in Chapadinha municipality, Maranhão State. The scents eucalyptol, eugenol and vanillin were utilized, between 07:00 and 17:00hr, to attract the euglossine males. Cotton balls were dampened with the scents and suspended by a string on tree branches 1.5m above soil level, set 8m from one another. The specimens were captured with entomological nets, killed with ethyl acetate and transported to the laboratory to be identified. A total of 158 individuals and 14 species of bees were recorded. The genus Eulaema was the most representative group of euglossine bees in relation to the total number of the sampled individuals, accounting for 50.6% of bees followed by Euglossa (26.6%), Eufriesea (15.2%) and Exaerete (7.6%). The most frequent species were Eulaema nigrita (27.8%), Eulaema cingulata (19%) and Euglossa cordata (18.3%). Many species typical of forested environments were found in samples, like Euglossa avicula, Euglossa violaceifrons and Eulaema meriana, emphasizing the role played by the Gallery Forests as bridge sites to connect the two great biomes of Amazonia and Atlantic Forest. The occurrence of Exaerete guaykuru represents the second record of this species for the Neotropical region, and both records coming from the Gallery Forest zones. The male euglossine bees were sampled mainly in the dry season, where 62.5% of the individuals were collected in that period. Eufriesea species appeared at the baits only in the wet season. The hourly frequency of bees at scent baits showed a clear preference for the morning period, where 87.9% visited the baits from 07:00 to 12:00hr. The euglossine bee fauna found in the Northeastern Maranhão Cerrado is represented chiefly by species of large geographic distribution and by some forest bee species, where their occurrence is maybe related to to the environmental conditions supported by the
