“…During the Program, several papers were published in international journals (e.g. Pansarin et al 2008a,b, 2018, Sazima et al 2009, Brito et al 2010, Agostini et al 2011, Amorin et al 2013, Moré et al 2012, 2017, Avila et al 2015, Saab et al 2021.…”

“…Such studies used different approaches, but most of them had a greater focus on plants. In those studies, researchers explored questions related to floral traits, such as differences in stamen sizes and their relationship to pollination (Valadão-Mendes et al 2022, Saab et al 2021 and the functional convergence between flowers of different families (Sazima et al 2009). The floral resources offered by plants were studied in detail, analyzing the floral anatomical structure, nectar production dynamics, and chemical composition of the different resources (Pansarin et al 2008a, Agostini et al 2011, Souza et al 2017, Guimarães et al 2018.…”

Interactions between plant and pollinators are associated with the origin and maintenance of species diversity, as well as ecosystem functioning. The potential of pollination as an ecosystem service is evidenced by its association with food production. Understanding pollination at the landscape scale is essential for characterizing the pollination service for several crops that depend on pollinators for fruit and seed set that make up the human diet. Our aim was to carry out a literature review of studies and projects funded by BIOTA/FAPESP to illustrate the main research approaches developed in the field of Pollination Biology, especially related to plant-pollinator interactions. Plant-pollinator interactions in the Atlantic forest were leveraged as a result of this long-term research program, during which several papers were published in international journals. Pollination by bees (melittophily) was the most representative pollination system studied. In addition to melittophily, other interactions were studied such as pollination by hawkmoths (sphingophily), by hummingbirds (ornithophily) and by bats (chiropterophily). The specific mutualistic relationships between fig trees and fig wasps were also subject of studies within the Program. At the beginning of the BIOTA/FAPESP Program, there were many gaps in basic information about pollination and breeding systems of Brazilian native plant species. Thus, the Program was fundamental to fuel research on the natural history of plants and pollinators from the Atlantic forest. Overall, the Program funded studies that investigated themes such as functional pollination ecology, pollinator effectiveness, plant population genetics, structure and dynamics of plant-pollinator interaction networks, as well as geographic distribution and macroevolution of pollination systems, as well as genetic and molecular studies of native plant populations focusing on pollen flow and genetic structure of populations. Additionally, studies on pollination in the context of landscape ecology had the aim of assessing the effects of forest fragmentation on the functioning of plant populations and their interactions with pollinators and the relationships between landscape structure and ecological processes, biodiversity, and ecosystem service. Therefore, the Program had a prominent role in producing basic data with great implications for understanding the ecology and promoting the conservation of plant-pollinator interactions.

“…Therefore, these characteristics may favor the higher visitor richness in this species, which encompass specialized and non-specialized pollinators (Arroyo 1981;Brito et al 2017), although restricted to large-and mediumsized bee species. On the other hand, since S. parahyba is one of the first species in flower after the winter months, the high number of pollinators may also be related to scarcity of other flowering species, with exception of the flowering events of some sympatric Malpighiaceae species in the vicinity whose flowers were visited by the same Centris bee species (Sazima et al 2009). …”

This study describes the floral phenology and morphology, reproductive biology and pollinators for eight legume tree species, Schizolobium parahyba, Senna macranthera, and Senna multijuga (Caesalpinioideae), as well as Andira fraxinifolia, Lonchocarpus cultratus, Pterocarpus violaceus, Swartzia oblata, and S. simplex (Papilionoideae), in the Atlantic Forest in Southeast Brazil. All the studied species showed an annual flowering pattern, and almost all are of the cornucopia-flowering type, with the only exception being Swartzia oblata, which was of the steady-state type. In general, the legume flowers studied are conspicuous, mostly medium-sized, and offer nectar and/or pollen as a resource. Self-incompatibility associated with the production of many flowers and consequent pollen discounting due to self-pollination may contribute to low fruit set of these species in natural conditions. Fifty bee species were recorded visiting the flowers, with medium to large-sized Apidae bees, such as Bombus morio, and species of Xylocopa, Centridini and Euglossina, which were among the most frequent visitors and major pollinators. These bees showed high floral constancy, thus they are significant to the reproductive success of these tree species. This study provides information regarding the interactions between bees and these eight legume species and evaluates the importance of pollinators for their sexual reproduction.

“…A morfologia da pétala estandarte possui importância na história evolutiva entre Malpighiaceae e a guilda de abelhas coletoras de óleo, em especial as abelhas da tribo Centridini (Sazima et al, 2009;. Essas abelhas possuem grande porte, não raros e comumente consideradas os principais polinizadoras das flores de óleo .…”

“…Assim, a pétala estandarte tem a base mais robusta em comparação às outras quatro pétalas (Fig. 1) e deve possuir resistência suficiente para o contato da abelha durante a visita e mesmo com a intrínseca pressão de seleção (Sazima et al, 2009) exercida sobre ela ainda existem variações morfológicas, de modo que possíveis variações sejam exibidas de acordo com a simetria da pétala estandarte. Assim, dada a importância da pétala estandarte para as abelhas coletoras de óleo, a escolha de flores com pétalas estandarte mais vigorosas deve ser um comportamento conservado ao longo da história evolutiva das abelhas coletoras de óleo, consequentemente flores com maior simetria nessas pétalas promovem a manutenção desse comportamento.…”
