More About Euglossine Bees in Amazonian Forest Fragments
Biotropica, 1991 Male euglossine bees were captured monthly for one year in modified McPhail traps baited with cineole, methyl salicylate, and skatole. The traps were operated 90 km north of Manaus, Brazil in continuous terra firme forest and forest fragments of 1, 10, and 100 ha. Of the 16 species of euglossine bees captured, Euglossa chalybeata and Eg.

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

Nectar-foraging behavior of Euglossine bees (Hymenoptera: Apidae) in urban areas [PDF]
Apidologie, 2008 Euglossine bees have been described as long-distance pollinators because of their great flight capacities although flight capacity is not necessarily correlated to home range. Here we report the nectar-foraging behavior of two euglossine species (Euglossa cordata and Eulaema nigrita) in urban areas and the predictive power of wing wear as an age ...

Harvesting the Casualties of War: <i>Macrogerodonia peruviana</i> Rove Beetles Prey Exclusively Upon Wounded <i>Trigona</i> spp. Stingless Bees (Coleoptera: Staphylinidae; Hymenoptera: Apidae). [PDF]
Ecol EvolWe report a previously undescribed trophic interaction in which Macrogerodonia peruviana rove beetles prey exclusively on wounded or recently killed Trigona stingless bees generated during aggressive conflicts at carrion. Field observations and choice experiments showed that beetles selectively targeted injured Trigona while ignoring carrion and other ...

Dimorphic enantiostyly and its function for pollination by carpenter bees in a pollen-rewarding Caribbean bloodwort. [PDF]
Am J BotAbstract Premise Flowers that present their anthers and stigma in close proximity can achieve precise animal‐mediated pollen transfer, but risk self‐pollination. One evolutionary solution is reciprocal herkogamy. Reciprocity of anther and style positions among different plants (i.e., a genetic dimorphism) is common in distylous plants, but very rare in

Corallorhiza striata is the first example of a pseudocopulatory orchid in North America and an instance of "double deception" in fully mycoheterotrophic plants. [PDF]
Am J BotAbstract Premise Orchids have many pollination strategies, from highly species‐specific mutualisms with insects to deceit pollination, including sexual deception. The family also has the most leafless, parasitic species (mycoheterotrophs) of any plant family.

Acta Botânica Brasílica, 2022 Male euglossine bees (Euglossine: Apidae) pollinate flowers of as many as 1,000 Neotropical plant species and there is evidence that blooming in these plants is synchronized with the seasonality of euglossine pollinators.

Plant Biol (Stuttg)Human‐invisible but bee‐visible UV patterns in flowers aid pollination by signalling to pollinators and protecting vulnerable DNA in pollen. ABSTRACT Ultraviolet light shining on flowers has various effects. In this review we assess functions of UV pigments and UV reflection patterns in flowers, including visual signalling by reflectance, fluorescence,

Life history induces markedly divergent insect responses to habitat loss. [PDF]
J Anim EcolThis study pioneers the use of deep learning to rapidly assess over 22,000 Amazonian insects, revealing life history‐dependent winners and losers from forest loss. It shows that terrestrial insects decline while aquatic insects thrive, with body size influencing dispersal, offering key insights for biodiversity conservation in tropical fragmented ...

Phylogenetic history shapes the composition of floral scents in a specialized pollination mutualism. [PDF]
New PhytolSummary Most studies of the chemical ecology of plant–pollinator interactions emphasize the role of pollinator‐mediated selection in shaping floral scent composition. Nevertheless, phylogeny may constrain the metabolic pathways underlying these profiles, thereby influencing the evolutionary trajectory of the emitted signals.
