Daily activity patterns of visits by males of four species of Eulaema (Apidae: Euglossina) to odor baits in a tropical forest fragment in Bahia, Brasil

open access: yesZoologia, 2009
Several studies have been conducted with bees of the subtribe Euglossina using odor baits as attractants. The objective of this study was to analyze the daily activity pattern of visits by males of four species of Eulaema - Eulaema nigrita Lepeletier ...

Diversity and distribution of orchid bees (Hymenoptera: Apidae, Euglossini) in Belize [PDF]

open access: yesPeerJ, 2023
Background Orchid bees are abundant and widespread in the Neotropics, where males are important pollinators of orchids they visit to collect fragrant chemicals later used to court females.

Floral Integration and Phenotypic Selection on Floral Traits of <i>Ipomoea cavalcantei</i> (Convolvulaceae), a Rare, Endemic, and Endangered Species to the Amazon Ironstone Outcrops. [PDF]

open access: yesEcol Evol
This paper analyzed the evolutionary potential of Ipomoea cavalcantei (an endemic species from the Amazon) by using floral integration and phenotypic selection analysis. The analyzed population presented floral integration in style length, probably due to selective pressures from pollinators on floral traits related to pollen deposition.

Mountain colonization precedes shifts away from bee pollination in Melastomataceae. [PDF]

open access: yesNew Phytol
Summary Shifts among different groups of pollinators are central in the evolution of flowering plants, yet mechanisms underlying pollinator shifts remain unclear. Environment‐induced reduction in pollinator availability and hence efficiency may destabilize ancestral plant–pollinator interactions and trigger shifts to new, more efficient pollinators ...

Plants, Pollinators and Pheromones: Promises and Lies of Semiochemicals. [PDF]

open access: yesPlant Cell Environ
ABSTRACT Pollination is traditionally regarded as a quintessential mutualism, yet many plants employ deceptive strategies to achieve reproductive success. Among the most intriguing is sexual deception, wherein flowers mimic the sex pheromones and visual signals of female insects to attract male pollinators—without providing any reward.

Untangling biodiversity interactions: A meta network on pollination in Earth's most diverse tropical savanna. [PDF]

open access: yesEcol Evol
We addressed how pollination meta network with vertebrate and invertebrate species is assembled in the world's most diverse savanna and identified potential biogeographical bias within the region. We found a generalization of interactions at the meta network level but a high degree of specialization within the modules, where bees are the module ...

Pollination and plant reproduction in the Cerrado, the world's most biodiverse savanna. [PDF]

open access: yesBiol Rev Camb Philos Soc
ABSTRACT The Brazilian Cerrado is a continental‐wide biodiversity hotspot and the most species‐rich savanna ecosystem in the world. The main aspect characterising this biodiversity is that the landscape is arranged as an intricate mosaic of different plant formations, including grasslands, savannas, and forests, each harbouring distinct but ...

Using ecological niche models and niche analyses to understand speciation patterns: the case of sister neotropical orchid bees. [PDF]

open access: yesPLoS ONE, 2014
The role of past connections between the two major South American forested biomes on current species distribution has been recognized a long time ago. Climatic oscillations that further separated these biomes have promoted parapatric speciation, in which

Going up: new altitudinal records of orchid bees (Hymenoptera: Apidae) in the inter-Andean valleys of southern Ecuador and their potential dispersal route

open access: yesRevista Chilena de Entomología, 2023
Orchid bees are a conspicuous and ecologically important group of insects, commonly distributed at medium and low altitudes in tropical ecosystems. Therefore, new recordings of orchid bees at higher altitudes are interesting.
