Orchid bees - masters parfumiers of the natural world

Orchid bees – masters parfumiers of the natural world

Ever wondered what’s inside your favourite bottle of perfume (or after-shave)? How many compounds – fragrance notes – go to make that seductive smell? Turns out that there are lots, maybe 30 or 40 per perfume? It’s all a perfumers (parfumier in French) secret of course; the ‘formula’. But there are thousands of aromatic sources to choose from; natural and synthetic. I came across a website…

HEAVY METAL

This bumble bee sized shimmering gladiator formed from molten blues and greens was collected by Tim McMahon a few days ago in the Bagaces region of Costa Rica, where he used chemical lures similar to the orchid oils that these bees gather the canopy dwelling orchids.   A large, parasitic orchid bee (Exaerte smaragdina) the equally large  Eulaema and Eufriesea host species are not so happy to have these bees around.

new: Dry future climate could reduce orchid bee habitat

New Post has been published on http://www.mybiologica.com/47276/agriculture-en/dry-future-climate-could-reduce-orchid-bee-habitat.html

Dry future climate could reduce orchid bee habitat

During Pleistocene era climate changes, neotropical orchid bees that relied on year-round warmth and wet weather found their habitats reduced by 30 to 50 percent, according to a Cornell University study that used computer models and genetic data to understand bee distributions during past climate changes.In previous studies, researchers have tracked male and female orchid bees and found that while females stay near their nests, male orchid bees travel, with one study concluding they roam as far as 7 kilometers per day. These past findings, corroborated by genetic data in the current study, reveal that males are more mobile than females.The study, published online in the journal Molecular Ecology, has important implications for future climate changes.”The dataset tells us that if the tendency is to have lower precipitation in combination with deforestation, the suitable habitat for the bees is going to be reduced,” said Margarita Lpez-Uribe, the paper’s first author and a graduate student at Cornell.The good news is that since male orchid bees habitually travel far, they can keep bee populations connected and healthy.”The males are mediating genetic exchange among populations, maintaining connectivity in spite of fragmentation of habitats,” said Lpez-Uribe. “This is a possible mechanism bees could use to ameliorate the negative impacts of population isolation resulting from future climate changes and deforestation.”By looking at current climate and bee distributions, Lpez-Uribe and colleagues assessed parameters of climate conditions that each of three bee species within the genus Eulaema could tolerate physiologically, including temperature and precipitation variability. She found that one of the three species, Eulaema cingulata, was three times more tolerant to a variety of climatic conditions.By proceeding with the caveat that physiological tolerance has remained constant — species tend to be evolutionarily conservative about shifting their niches — the researchers used computer models to simulate past bee distributions based on climate conditions in the Pleistocene. The results showed that in the past, during periods when the neotropics had lowered precipitation, each species experienced significant reduction in suitable habitat, with E. cingulata maintaining the largest geographical ranges.Climate and ecological niche computer model simulations were closely matched by genetic data of the two less-tolerant orchid bee species. The genetic data included mitochondrial markers, which are only inherited from females, and nuclear markers, which come from males and females. The mitochondrial DNA showed that individual bees in one geographic area were more closely related to each other than to bees from other areas. The findings suggest the maternal lines of these bees remained in the area and shared the same pools of DNA over time. But the bi-parental nuclear DNA showed more variation between individuals within an area, offering evidence that males traveled and shared their DNA with other regional groups.Orchid bees live in the neotropics, an ecozone that includes part of South and Central America, the Mexican lowlands and the Caribbean islands. …

Orchid bees collecting Perfume from a Tulip orchid by Andreas Kay Via Flickr: watch my VIDEO at rumble.com/v5txm7 This footage from Jardín Botánico "Las Orquídeas" in Puyo, Ecuador shows orchid bees of the genera Euglossa (metallic green) and Eulaema (yellow, black and brown) collecting perfume from the Tulip orchid Anguloa uniflora. These orchids do not produce nectar to attract pollinators, but fragrances which are collected by male orchid bees (Euglossini) in order to seduce females. The bees collect perfume with brushes on their forelegs and transfer it in flight via the middle legs to cavities on the enlarged hind legs as can be seen in this video: rumble.com/v45gn3 The transfer of the pollinaria from an orchid to a bee can be observed in this video: www.youtube.com/watch?v=hW6qcnmWOaQ.
