Catasetum species have an intriguing mechanism of pollinarium ejection after a mechanical stimulus of the column extensions, the antennae, of staminate flowers. The subgeneric classification of Catasetum is based on antenna morphology, although the subgenera have not been tested phylogenetically yet. With this in view, our goal was to test the mono...
Article
Tropical studies traditionally describe insect diversity variation throughout the year. The temporally structured responses of insect assemblages to climate seasonality vary across ecosystems due to gradients of resource availability and limiting ecological factors. These idiosyncratic responses might be particularly true across the vast geographic...
Article
Insect pollinators, including bees and wasps, are facing a marked decline in their native populations, caused mainly by human activities, such as forest fragmentation, urbanization, and the use of agrochemicals. To help mitigate the rapid decline of pollinators, new efforts towards understanding basic and applied aspects of these organisms are nece...
