Abstract Worldwide distributed tropical savannas were established only in the Miocene, with climatic cooling and rise of C4 grasses. However, there is evidence for an earlier presence of savanna-like vegetation in southern parts of South America. Here we investigated the biogeographic history of a clade of solitary bees which have endemic groups in areas covered by savannas and other types of open vegetation as well as forested areas. We hypothesized that these bees originated in savanna-like bi...

Abstract It has been known since Stefan Vogel’s observations in 1969 that solitary female oil bees collect fatty floral oils from specialized oil-secreting plants with the aid of hairy patches on either their legs or abdomen, a reward used as food for their larvae and/or to line their brood cells. Similar adaptations are also known from male oil bees, although the purpose of their oil-collecting behavior has not yet been clarified. Here, we describe a novel pollination system involving male Para...

a b s t r a c t Oil flowers are spread over eleven angiosperm families and exploited by bees specialized on oil gath- ering. This reward is produced by glandular surfaces of specific floral whorls called elaiophores. Unlike trichome elaiophores, such as those of Plantaginaceae, Krameria species bear lateral petals modified into epithelial elaiophore, convergently similar to oil-secreting Malpighiaceae calyx. Krameriaceae is an oil- offering monotypic group of eighteen species with little informa...

Given human-related changes, quality distributional data are required for consistent conservation. Still, the lack of proper biogeographic information is a major setback for many groups. Here, we use new occurrences for Aglae caerulea in the Cerrado to model its potential distribution. We used Maximum Entropy (MaxEnt) and Genetic Algorithm for Rule-Set Production (GARP) algorithms in different modeling runs and both previous and new A. caerulea occurrences to predict this species distribution. M...

Abstract Oil-bee/oil-flower mutualism evolved through multiple gains and losses of the ability to produce floral oil in plants and to collect it in bees. Around 2000 plant species are known to produce floral oils that are collected by roughly 450 bee species, which use them for the construction of nests and for the larval food. The Plantaginaceae contain several Neotropical species that produce floral oils, the main reward offered by these plants. In the genera Angelonia , Basistemon , Monopera ...

Several groups of solitary bees, known as oil-collecting bees, gather lipids from flowers that offer them as their main reward to pollinators. In the Neotropical region, oil-collecting bees belong to the tribes Centridini, Tapinotaspidini, and Tetrapediini (Apidae: Apinae). The floral oils collected by females of these groups are used as larval food or in nest construction. The interaction of these bees with oil flowers is characterized by the presence of specialized structures for oil collectio...

In this study a current list of the oil-collecting bees from Sao Paulo State is presented, with their occurrences associated to the mainly biomes of the state: Atlantic Rainforest and Cerrado. Some data on the biology of the common species are presented. We discuss about the sample gaps for the state.
