Pollination of the strongly scented Sarcoglottis acaulis (Orchidaceae) by male orchid bees: nectar as resource instead of perfume.

Plant biology, 2021
The Neotropical orchid genus Sarcoglottis comprises ~40 species, which emit strong floral scents, presumably involved in pollinator attraction. Information on basic aspects of its natural history is scant, with the few studies available so far pointing ...

Scaling of Nectar Foraging in Orchid Bees

The American Naturalist, 2007
Morphology influences the rate at which foraging bees visit nectar flowers, the quantity of nectar they must consume to fuel their activities, and, consequently, the profitability of flower species. Because feeding time is a major determinant of visitation rate, I used a biomechanical model to examine how energy intake rate (E) varies with sucrose ...

Genetic diversity and population structure of orchid bees from the Brazilian savanna

Journal of Apicultural Research, 2021
Based on microsatellite markers and non-lethal sampling of orchid bee males, we assessed the genetic diversity and population structure of three species, Euglossa pleosticta, Euglossa imperialis, and Eulaema nigrita, collected from forest remnants in the

Euglossini orchid bees in Panama: a comprehensive bibliometric overview of trends, networks, and gaps

Studies on Neotropical Fauna and Environment
Orchid bees are renowned for their collection of fragrances from orchids and other flowers. Despite their significant role in flower pollination, there is a lack of comprehensive summaries regarding research.

Orchid Bees of forest fragments in Southwestern Amazonia [PDF]

Biota Neotropica, 2013
Bees of the tribe Euglossini are known as orchid-bees. In general, areas with more vegetation cover have greater abundance and diversity of these bees. This study investigated the effects of forest fragmentation on assemblages of the euglossine bees in the region of Rio Branco municipality, State of Acre, and surrounding areas.

Analyze the Species Richness and Abundance of Orchid Bees in Eastern Ghats Rainforests

Journal of Advances in Science and Technology
This is one way in which the biodiversity of the Amazon is priceless. Geography, climate, and biotic interactions have always played a role in shaping evolutionary pathways, and these factors continue to do so now.

Island Biogeography Theory and the Island Rule in Orchid Bees in Panama

Journal of Biogeography
The study of the theory of island biogeographic (TIB) has focused mainly on plants and vertebrates, with support for the predictions that species richness decreases with distance from the mainland and increases with island size.

Body size and abundance patterns of male orchid bees in a fragmented Neotropical landscape

Insect Conservation and Diversity
Understanding the relationship between functional traits and fragmentation is crucial for promoting biodiversity and ecosystem function. Orchid bees (Euglossini) are important pollinators in Neotropical forests, but how body size may be associated with ...

Chemical niche differentiation among sympatric species of orchid bees [PDF]

Ecology, 2009
Male Neotropical orchid bees (Euglossini) collect volatile substances (fragrances) from flowers and other sources (e.g., decaying wood) and store them in specialized hind tibial pockets. The accumulated chemicals are later emitted during courtship display, presumably to lure conspecific females for mating.

The transcriptomic signature of adaptations associated with perfume collection in orchid bees

Journal of Evolutionary Biology, 2023
Abstract Secondary sexual traits can convey information on mate quality with the signal honesty maintained by the costly nature of trait expression. Mating signals are also often underpinned by physiological, morphological, and behavioural adaptations, which may require the evolution of novelty, but the genetic basis in many cases is ...
