“…A number of studies with native stingless bees highlight the importance of the Fabaceae family as the main supplier of pollen (Aleixo et al, 2013;Azevedo-Costa et al, 2013;MaiaSilva et al, 2014). Studies performed by Alves et al (2006) to identify M. mandacaia nectar sources in the state of Bahia- Brazil, Souza et al (2015) of M. scutellaris on the north coast of Bahia, Matos and Santos (2016) of M. scutellaris in an Atlantic Forest area in the state of Bahia, and of Melipona fasciculata in the state of Maranhão-Brazil, indicated that the greatest diversity of types was also for the Fabaceae family.…”

The objective of this study was to identify the species of pollen supplying plants that constitute the trophic niche of Melipona mandacaia in an urban area in the Caatinga domain (a tropical arid landscape). The collection of pollen in the colonies was carried out every 15 days, from October 2014 to September 2015. The pollen was removed directly from the storage pots in three distinct colonies. A total of 24 samples were analyzed and compared with the reference pollen collection, pollen catalogs and specialized literature. For the quantitative analysis, at least 1000 pollen grains per sample were identified. A total of 39 pollen types were identified, distributed in 17 botanical families, being one an indeterminate type. The most represented family was the Fabaceae (n = 16). The most frequent types were Leucaena leucocephala, Mimosa pudica and Melochia sp. There was a significant positive correlation between temperature and the number of pollen types throughout the study. Relative humidity and rainfall were abiotic variables that did not present a significant correlation. The rarefaction curve showed that probably most of the pollen types collected by the bees studied were sampled, since the accumulation curve showed a progressive tendency to stabilization, indicating that there was sample adequacy of the pollen types. The analysis of similarity revealed a high sharing of pollen sources between colonies.

“…(Aleixo et al, 2013;Imperatriz-Fonseca et al, 2012). This way, the complementation of ecological data, obtained through the palynological analyses, is an important step in the rational exploration for the development of the preservation programs for these bees.…”

ResumoOs visitantes florais são animais que buscam, nas flores, recursos para si ou para sua prole. Às vezes uma mesma planta pode receber um espectro grande de visitantes, como é o caso de espécies cujas flores oferecem muito néctar. Porém, nem todo visitante floral realiza a polinização. Para ser um polinizador efetivo é necessário cumprir alguns requisitos, como: contato com a antera e o estigma, frequência de visita suficiente, fidelidade floral e a realização de uma rota adequada de visitação. Em muitos trabalhos sobre a estrutura de comunidades e, principalmente, sobre a rede trófica (ex. animal-planta), os autores adotam o termo polinizador para todo e qualquer visitante floral, categorizando-os com o mesmo papel e função para a planta. Neste trabalho, relatamos casos de visitantes florais que são polinizadores legítimos e efetivos, dos quais a planta depende de seu serviço para produção de frutos e sementes, distinguindo-os daqueles visitantes que não efetuam a polinização, ou não se tem certeza que o façam. Assim, espera-se ilustrar as diferenças, dando à devida importância e o peso correto para os muitos visitantes. Utilizamos abelhas como modelo, mas a idéia pode ser extrapolada para qualquer outro grupo de polinizador. Palavras-chave: flores, rede de interação mutualista, reprodução vegetal, transferência de pólen, visita legítima. AbstractFlower visitors are animals that generally seek resources in flowers for themselves or their offspring. Sometimes the same plant may receive a broad spectrum of visitors, such as nectar species. However not all floral visitors complete pollination. To be an effective pollinator is necessary to fulfill some requirements, such as: contact with the anther and stigma, enough frequency of visits, fidelity to the plant, and the realization of a suitable route of visitation. In many works on the structure of communities and especially of food webs (animal-plant), the authors adopt the term pollinator for each and every flower visitor categorizing them with the same role and function for the plant. In this work we report cases of floral visitors who are legitimate and effective pollinators of which the plant depends on its service for the production of fruits and seeds, distinguishing them from those visitors who do not pollinate, or are not sure to do so. Thus, it is expected to illustrate the differences, giving due importance and the correct weight for the many visitors. We used bees as a model, but the idea can be extrapolated to any other pollinator group.

“…The vegetation of the university campus is composed of both native species of seasonal semi-deciduous forest and exotic plants (vegetation cover of the campus: ~ 75 ha; Pais & Varanda, 2010). The area directly surrounding the meliponary presents a high diversity of potential food sources for bees (Faria et al, 2012;Aleixo et al, 2013). The local climate is characterized through two welldefined seasons, a hot-rainy season from September/October to April, and a cold-dry season from May to August/September.…”

Environmental windows for foraging activity in stingless bees, Melipona subnitida Ducke and Melipona quadrifasciata Lepeletier (Hymenoptera: Apidae: Meliponini) IntroductionDue to their impact on many aspects of colony life, abiotic factors are considered key determinants for the geographical distribution of social bee species (Michener, 1974). An environmentally influenced aspect of vital importance for colony functioning is food collection. The success of foragers, which is crucial for the maintenance and survival of the colonies, is affected both directly and indirectly by climatic factors. Associated with the morphological and interrelated physiological peculiarities of a bee species -such as body size and colouration -abiotic factors determine the timing of food collection (daily onset and end) and the food patch choice (sunny versus shaded patches) (Biesmeijer et al., 1999; AbstractThe foraging success of a bee species is limited to an environmental window, a combination of optimal ambient temperatures and resource availability. Mismatches between flowering and optimal foraging temperature may lead to a reduction of a colony's food intake and, eventually, of brood production. In the present study, we evaluated the pollen foraging activity of two native Brazilian meliponine species Melipona quadrifasciata Lepeletier and Melipona subnitida Ducke at the campus of the University of São Paulo at Ribeirão Preto (March, 2010 -January, 2011). Whereas M. quadrifasciata naturally occurs in the study region (Brazilian Southeast), M. subnitida is restricted to the Brazilian Northeast. This difference in geographic distribution and concordant climatic specializations suggest differences concerning the environmental window between the two species. We investigated potential differences between the species concerning the thermal window within which foraging occurs, and associated differences in foraging activity, visited pollen sources, and colony survival. The lower temperature limit for M. subnitida (17 ° C) was 5 °C above the lower temperature limit found in M. quadrifasciata (12 °C). This difference resulted in a considerable time lag concerning the onset of foraging between the bee species (maximum: 120 minutes), mainly during the cold-dry season. Due to this delay in foraging, M. subnitida could not benefit from highly profitable pollen sources (massflowering trees) that were in bloom during this time of the year. Possibly because of this deficit in pollen intake, three of the six monitored colonies of M. subnitida did not survive the study period.
