Tree traits are a stronger predictor of bee traits and species richness than taxonomic diversity
Functional Ecology, Volume 39, Issue 1, Page 281-292, January 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract Functional traits help to understand biological diversity and the mechanism by which ecological communities are structured and how they respond to the environment. For example, the high tree species diversity within tropical forests can be grouped into a few functional ...

Diversidade de Euglossini (Hymenoptera: Apidae) em áreas de Cerrado do Triângulo Mineiro, MG.
Bioscience Journal, 2007 Os Euglossini são abelhas típicas de matas tropicais úmidas, mas poucos estudos têm sido feitos estimando parâmetros ecológicos desse grupo em outras fitofisionomias.

Non‐floral scent sources of orchid bees: Observations and significance
Biotropica, Volume 57, Issue 1, January 2025.We observed male euglossines collecting scent at 21 different non‐floral sources in Central and South America, strengthening the view that these sources play a central role in euglossine perfume biology. A Protium tree provided over 50% of the perfumes for Eufriesea corusca and was repeatedly revisited.

Molecular Ecology, Volume 33, Issue 23, December 2024.ABSTRACT Hymenopteran queens are collectively highly fecund, often long‐lived individuals that undergo dramatic physiological changes after they mate and establish a nest. However, the degree to which these changes are conserved among species with different life histories is not well‐defined.

Time management and nectar flow: flower handling and suction feeding in long-proboscid flies (Nemestrinidae: Prosoeca) [PDF]
, 2013 A well-developed suction pump in the head represents an important adaptation for nectar-feeding insects, such as Hymenoptera, Lepidoptera and Diptera.

How does climate change impact social bees and bee sociality?
Journal of Animal Ecology, Volume 93, Issue 11, Page 1610-1621, November 2024.Climate change is rapidly reorganizing the distributions and expression of social phenotypes in bees. Because sociality mediates climate responses, and climate drives social evolution, understanding these linkages between sociality and climate is crucial for predicting vulnerability and resilience across bee taxa. Abstract Climatic factors are known to

Food-Foraging Behavior of Male Euglossini (Hymenoptera: Apidae): Vagabonds or Trapliners?
Biotropica, 1982 The nectar-foraging behavior of male euglossine bees (Hymenoptera: Apidae) was studied at a population of Calathea latifolia (Marantaceae) on Barro Colorado Island, Panama, for two weeks. Several marked males of Exaerete smaragdina and Euglossa imperialis foraged at C. latifolia on a daily basis.

More than symbioses : orchid ecology ; with examples from the Sydney Region [PDF]
, 2013 The Orchidaceae are one of the largest and most diverse families of flowering plants. Orchids grow as terrestrial, lithophytic, epiphytic or climbing herbs but most orchids native to the Sydney Region can be placed in one of two categories.
