Bumblebees learn the sweet smell of foraging success
Bumblebees use flower scent to guide their nest-mates to good food sources, according to scientists from Queen Mary, University of London.
For any animal, finding food on its own can be time consuming and inefficient; social animals such as bees reduce these problems by informing their peers of...
Isotope analysis reveals foraging area dichotomy for Atlantic leatherback turtles
The beaches of French Guiana constitute a major reproduction site for leatherback turtles. This sea turtle, although a protected species, is threatened by human activity: it ingests plastics, get accidentally caught in fishing nets, sees its egg-laying sites destroyed and its adults hunted illegal...
The value of variation: Ecologists consider the causes and consequences
