“…On the other hand, considering the two areas studied herein, A. paucifolia was found at low frequencies in some nests of C. terminata and C. analis. This data suggest that A. paucifolia can be used as a source of nectar, as reported in some studies with C. tarsata and C. trigonoides from Caatinga biome (Dórea et al, 2009;Dórea et al, 2010a;Dórea et al, 2013).…”

Floral Resource Partitioning between Centris (Heterocentris) analis (Fabricius, 1804) and Centris (Heterocentris) terminata Smith, 1874 (Hymenoptera, Apidae, Centridini), in an Urban Fragment of the Atlantic Forest

The knowledge on plant species used for the collection of floral resources is crucial to understanding interactions between plants and bees. The aim of the present study was to identify floral resources used by Centris analis and Centris terminata to provision brood cells and determine the niche breadth and overlap of these two species in a fragment of the Atlantic Forest in Brazil. This study was conducted at the Universidade Federal da Bahia and Parque Zoobotânico Getúlio Vargas, both of which are located in urban areas of the city of Salvador in the state of Bahia. Twelve and eight pollen types were identified in C. analis and C. terminata nests, respectively. The most frequent pollen types were from species of Malpighiaceae and Fabaceae. A larger trophic niche breadth was found in the Parque Zoobotânico Getúlio Vargas for C. analis and in the Universidade Federal da Bahia for C. terminata. Pianka’s index demonstrated trophic niche overlap between C. analis and C. terminata, which was greater in the Parque Zoobotânico Getúlio Vargas. This study is the first to provide data on plants used as food sources by species of the genus Centris in a fragment of the Atlantic Forest situated within urban areas.

“…Pollen represents one of the main aspects of habitat quality for bee populations. Many Centridini species use Byrsonima as a pollen source (Aguiar & Gaglianone, 2003;Dórea et al, 2010;Rabelo et al, 2012), and, therefore, we expect that fluctuations in Byrsonima abundance directly influence bee reproduction.…”

The Similar Usage of a Common Key Resource Does Not Determine Similar Responses by Species in A Community of Oil-collecting Bees

Variations in abundance and species richness among communities are often determined by interactions between biotic and abiotic factors. However, for communities composed of species that share a common specialization (such as similar foraging adaptations) it may be a key ecological factor involved in the common specialization that affects community variations. To evaluate this possibility, we characterized the guild of oil-collecting bees of a Neotropical savanna in Brazil and tested whether differences in Byrsonima abundance and availability of floral oil explain differences in species richness and abundance of oil-collecting bees of different tribes. Both the number of species and total abundance of Centridini species increased with the abundance of Byrsonima. One plausible explanation for the stronger adjustment between the abundance of Centridini and Byrsonima is that the abundance of these plants affects not only the availability of floral oil, but also of pollen. These findings indicate that the existence of a common specialization among different species does not homogenize their response to variations in a common explored resource.

“…Palynological analysis is an important tool in the study of bee food resources, and in the determination of the floral resources used by bees (Dórea et al, 2009;2010a;2010b;. The pollen stored in nests provides many data on bee foraging and help to fill the knowledge gap concerning the floral resources needed to maintain bee populations .…”

Due to deforestation and fragmentation of ecosystems, the management of bee populations targeting pollination services is increasingly urgent. Because urban environments are stressful, the dietary knowledge in such areas can help to cope with this issue in the near future. Using palynological analysis the floral resources used by Centris flavifrons, an important pollinator of crops and native plants was studied in an urban area. Byrsonima sericea type, Solanum paniculatum type, Cestrum type, and Myrcia type 1 together accounted for more than 93% of pollen grains foraged by females. It is noteworthy that this bee population depends on few plant species both for pollen and for oil. Furthermore, females showed flexibility to replace the primary pollen source in different breeding seasons, as well as one female could provision different cells in the same nest with different predominant pollen types. The importance of wastelands and natural areasis highlighted for keeping bee populations in urban areas. Amid discussions about loss of biodiversity, urban areas are seen with a potential to promote diversity as a result of designing and planning the cities to foster interaction between people and nature (Miller, 2005). Centris (Centris) flavifrons (Fabricius) has mainly a Neotropical distribution, occurring also in the Nearctic region in Sinaloa, Mexico (Moure et al., 2012) and is an important pollinator of Malpighia emarginata L., called West Indian cherry, and others agricultural crops, for example Passiflora alata Curtis (Gaglianone et al., 2010;Vilhena et al., 2012). It has also an important role in native plant species pollination in the Neotropical region, especially of Malpighiaceae, e.g. Sociobiology
