Bees get a buzz from caffeine
Scientists have today shown that caffeine improves a honeybee's memory and could help the plant recruit more bees to spread its pollen.
Herbivory discovered in a spider
(PhysOrg.com) -- There are approximately 40,000 species of spiders in the world, all of which have been thought to be strict predators that feed on insects or other animals. Now, scientists have found that ...
A bird-pollinated flower with a rather ingenious twist
When researchers studying several bird-pollinated species of Impatiens flowers in the mountains of western Cameroon noticed one with an odd, upwardly curving nectar spur, they couldn't imagine how any su ...
Honey bees demonstrate decision making process to avoid difficult choices
(Phys.org) —A new study on the metacognitive ability of honey bees suggests that they, like humans, avoid difficult decisions when they lack sufficient information to solve a problem.
Nectar: A sweet reward from plants to attract pollinators
Evolution is based on diversity, and sexual reproduction is key to creating a diverse population that secures competitiveness in nature. Plants had to solve a problem: they needed to find ways to spread their ...
Caffeine enhances bee memory
(Phys.org) —Caffeine is the naturally occurring drug most widely used by humans. In nature, though, it is reported to act as a bitter and toxic deterrent to herbivores, preventing leaves and seeds from ...
Researchers discover bees are picky pollinators
(Phys.org) —Huge swaths of the agricultural industry depend on the humble honeybee. According to the USDA, "about one mouthful in three in our diet directly or indirectly benefits from honey bee pollination." ...
Drunk Bats Manage To Pass Sobriety Tests
Pesticides not yet proven guilty of causing honeybee declines, new study says
The impact of crop pesticides on honeybee colonies is unlikely to cause colony collapse, according to a paper in the journal Science today. More research is now needed to predict the impact of widely-used agricu ...
Ants and carnivorous plants conspire for mutualistic feeding
An insect-eating pitcher plant teams up with ants to prevent mosquito larvae from stealing its nutrients, according to research published May 22 in the open access journal PLOS ONE by Mathias Scharmann and co ...
Just what makes that little old ant… change a flower's nectar content?
Ants play a variety of important roles in many ecosystems. As frequent visitors to flowers, they can benefit plants in their role as pollinators when they forage on sugar-rich nectar. However, a new study ...
Understanding the flight of the bumblebee
Scientists from Queen Mary, University of London have tracked bumblebees for the first time to see how they select the optimal route to collect nectar from multiple flowers and return to their nest.
Hummingbirds take no notice of flower color
Hummingbirds pay no attention to what colour a flower is when figuring out whether to raid it for nectar, the latest research suggests.
Bumblebees use logic to find the best flowers
Scientists at Queen Mary, University of London and the Zoological Society of London (ZSL), have discovered why bees copy each other when looking for nectar – and the answer is remarkably simple.
