Sociobiology, 2014 Although bees are important pollinators in several ecosystems around the world, studies on bee diversity in hygrophilous forests are scarce. This type of vegetation is restricted to permanently wet soils and, therefore, has particular floristic ...

Aerial litter mimicry: A novel form of floral deception mediated by a monoterpene synthase
Journal of Ecology, Volume 113, Issue 2, Page 302-321, February 2025.We report the first pollination system in which a flower imitates aerial litter, which refers to the arboreal plant litter in a forest. Our findings demonstrated that Meiogyne heteropetala flower fooled the aerial litter specialist Loberus sharpi by mimicking aerial litter in size, colour and odour.

Papéis Avulsos de Zoologia, 2019 Seasonal fluctuations in the abundance of orchid bees have already been reported. The variations in population dynamics may be expected to occur in more predictable and pronounced manners in environments with a clear distinction between rainy and dry ...

Beiträge zur Entomologie = Contributions to Entomology, 2008 Es wird eine neuartige morphologische Struktur bei Prachtbienen (Apinae: Euglossini) dargestellt. Diese findet sich posterolateral der Ocelli und wird als “Juxtocellarstruktur” bezeichnet. Sie wird in ihrer Ausprägung bei den Euglossinen beschrieben. Homologe Strukturen wurden bei verschiedenen verwandten Gruppen von Apidae gefunden, z. B.

Different Physiognomies and the Structure of Euglossini bee (Hymenoptera: Apidae) Communities
Sociobiology, 2018 Our aim was to evaluate the occurrence of orchid bees in remnants of the Atlantic Forest. We sampled specimens from five regions of Southeast Brazil, covering three different physiognomies of the Atlantic Forest (mixed Araucaria forests with high ...

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.

Genetics and Molecular Biology, 2005 Random amplified polymorphic DNA (RAPD) markers were used to analyze the genetic structure of Eufriesea violacea populations in three fragments (85.47, 832.58 and 2800 ha) of Atlantic rainforest located in the north of the Brazilian state of Paraná.

Prezygotic barriers effectively limit hybridization in a rapid evolutionary radiation
New Phytologist, Volume 244, Issue 6, Page 2548-2560, December 2024.Summary Hybridization is increasingly recognized as an important evolutionary process across the tree of life. In many clades, phylogenomic approaches have permitted unparalleled insight into the extent and frequency of hybridization. However, we continue to lack a deep understanding of the factors that limit and shape patterns of hybridization ...

, 1990 Male euglossine bees (Eugloua, Eulaema, Exaerete) were censused at regular intervals at chemical baits in Surinam, Trinidad, and Costa Rica. Fragrance foraging was initiated at ca 0700, peak activity occurred at ca 1100, and foraging ceased at ca 1430 ...

Pollination of Two Species of Dalechampia (Euphoriaceae) in Mexico by Euglossine Bees
, 1979 The large genus Dalechampia, including over 100 species of great vegitative diversity, has a basically uniform pseudanthial inflorescense. Investigation of two sympatric species is Mexico has shown considerable divergence in pollination adaptations. In D.
