The tiny pollinators are useful sentinels of what’s going on in an ecosystem, and might just be environmentalists’ best asset.

Source: National Centre for Biological SciencesSummary:Although at least 75 percent of our crop species depend on animal pollinators, little is known about their flower preferences. As global insect populations decline, it is of utmost importance for us to understand what factors attract wild pollinators to flowers, and how these preferences differ in the face of … More Laws of attraction: Pollinators use multiple cues to identify flowers across continents
Wednesday November 15, 2017 saw the official launch of one of the most ambitious conservation programmes in England – Back from the Brink. Project partners, volunteers and other distinguished guests met at Windsor Great Park to celebrate the launch of the programme, which aims to bring 20 species back from the brink of extinction. This is … More A Grassroots Organization Launch of ‘Back from the Brink’
Honeybee larvae develop into workers but not queens, in part, because their diet of beebread/pollen is enriched in plant miRNAs. While miRNAs are generally negative regulators of gene expression in eukaryotes, they also negatively regulate larval development when honeybee larvae consume beebread/pollen and take up plant miRNAs. Xi Chen and Chen-Yu Zhang’s group in Nanjing … More Cross-kingdom regulation of honeybee caste development by dietary plant miRNAs
Set your meetings, phone calls and emails aside, at least for the next several minutes. That’s because today you’re a bee. It’s time to leave your hive, or your underground burrow, and forage for pollen. Pollen is the stuff that flowers use to reproduce. But it’s also essential grub for you, other bees in your … More You’re a Bee. This Is What It Feels Like.
Bumble bees create foraging routes by using their experience to select nectar-rich, high-rewarding flowers. A study now suggests that bees actually forage more efficiently when flower sizes are large rather than small. This indicates that for these insect pollinators foraging quickly is more efficient than foraging accurately. Bumble bees create foraging routes by using their … More Bumble bees make a beeline for larger flowers
There are around 550 different bee species in Germany. Most of them are solitary bees. They don’t live in large beehives like the honeybee, but each female bee often builds multiple nests and feeds her offspring alone. Solitary bees use their short lifespan of a few weeks exclusively to reproduce and to provide food for … More Climate change threatens domestic bee species
