Bee competitive: Research reveals the impact of natural selection on nectar supply and demand
natural selection nectar supply and demand seasonal imbalances
2021/8/6
Theoretical research indicates that natural selection will increase existing seasonal imbalances between the supply of nectar from flowers and the demand from bees and other insects.

varying Arctic climate conditions impact vulnerable species
2021/4/9
New findings on the diet of Arctic foxes, determined by the condition of their teeth, show how varying climate conditions in the Arctic affect the animals that live there.In a U.S. National Scien...
Human activities could change the pace of evolution, similar to what occurred 66 million years ago when a giant asteroid wiped out the dinosaurs, leaving modern birds as their only descendants. That’s...
