Different Pollinators’ Functional Traits Can Explain Pollen Load in Two Solitary Oil-Collecting Bees [PDF]

Insects, 2020
Functional traits have been shown to be a good predictor of pollen load for some pollinator bee species, but little is known about solitary bees. In this study, I used two solitary oil-collecting bees to explore the impact of functional traits on the ...

Structural and Functional Co‐Adaptation of Plants of the Genus Lysimachia L. (Primulaceae) and Pollinating Insects of the Genus Macropis Panzer (Hymenoptera, Melittidae) [PDF]

Ecology and Evolution
The pollination system ‘oil‐collecting bees Macropis and oil‐producing plants Lysimachia’, probably originated a long time ago. Although much is already known about the biology and ecology of this fascinating interaction, we reveal here features of the ...

Oil collecting bees and Byrsonima cydoniifolia A. Juss. (Malpighiaceae) interactions: the prevalence of long-distance cross pollination driving reproductive success

Anais da Academia Brasileira de Ciências, 2014
Oil-collecting bees are the natural pollinators of oil-flower plants, but little is known about the pollination process and the effectiveness of their pollination service to the reproductive success of their host plants.

Comparison of Pollen-Collecting Abilities between Apis mellifera L. and Bombus terrestris L. in the Oil Tree Peony Field

Horticulturae, 2023
The lack of pollinators in the oil tree peony field was a serious problem for the seed yield. In the preliminary studies, we found that the seed rate of oil tree peonies was significantly improved by supplementing bees during the flowering stages in the ...

Chemical Characterisation of the Floral Oil of the Murici (Byrsonima sericea): Discovering the Constituents Used in Reproduction by Oil-Collecting Bees

Sociobiology, 2020
The recent decline in population of generalist bees such as those of the genera Apis and Bombus has shown the need to breed and manage a larger number of bee species.

Madagasikaria (Malpighiaceae): A New Genus from Madagascar with Implications for Floral Evolution in Malpighiaceae [PDF]

, 2002
Madagasikaria andersonii is described here as a new genus and species of Malpighiaceae from Madagascar. The phylogenetic placement of Madagasikaria was estimated by using combined data from ndhF and trnL-F chloroplast sequences and phytochrome (PHYC) and
