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

open access: yesSociobiology, 2017
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)

Oil-collecting bee–flower interaction network: do bee size and anther type influence the use of pollen sources? [PDF]

open access: yesApidologie, 2014
Pollination is an ecosystem service sustained by a differentiated use of resources among sympatric species. The bee size can influence the similarity in the use of resources, and poricidal anthers limit the access to pollen. Therefore, we evaluated the influence of body size and the anther type of pollen sources in Centridini–flower interaction network.

Bee Life in the City: an Analysis of the Pollen Provisions of Centris (Centris) flavifrons (Centridini) in an Urban Area

open access: yesSociobiology, 2017
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 ...

Epeoloides pilosulus (Cresson) Rediscovered in Michigan, with Notes on the Distribution and Status of its Macropis hosts. [PDF]

open access: yes, 2019
Epeoloides pilosulus (Cresson 1878) is one of the rarest bees in North America with only a handful of records since 1960. The last collection in Michigan was made in 1944.

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

open access: yesSociobiology, 2017
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 ...

Gut microbiota variation of a tropical oil-collecting bee species far exceeds that of the honeybee

open access: yesFrontiers in Microbiology, 2023
IntroductionInterest for bee microbiota has recently been rising, alleviating the gap in knowledge in regard to drivers of solitary bee gut microbiota. However, no study has addressed the microbial acquisition routes of tropical solitary bees. For both social and solitary bees, the gut microbiota has several essential roles such as food processing and ...

Nesting and reproductive habits of the solitary bee Centris analis in trap nests under a tropical climate

open access: yesRevista Ciência Agronômica, 2019
Pollination is a key factor in global agricultural production, and there is a need to increase the number of bee species that can be bred for pollination in agriculture, such as the oil-collecting solitary bee Centris (Heterocentris) analis (Fabricius ...

Conservation Value and Permeability of Neotropical Oil Palm Landscapes for Orchid Bees [PDF]

open access: yes, 2013
The proliferation of oil palm plantations has led to dramatic changes in tropical landscapes across the globe. However, relatively little is known about the effects of oil palm expansion on biodiversity, especially in key ecosystem-service providing ...
