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

...connections between these usually separate fields, we hope to initiate a new field of mathematical ecology that melds genetics, evolution, and dynamic foraging behavior into ecological models that will determine how intraspecific variation affects ecological dynamics and community structure," Bolnick said. ...

Seals quickly respond to gain and loss of habitat under climate change
