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.

Lizard blizzard survivors tell story natural selection
2017/9/4
An unusually cold winter in the U.S. in 2014 took a toll on the green anole lizard, a tree-dwelling creature common to the southeastern United States. A new study offers a rare view of natural selecti...

Two-step dialogue cladocera Bosmina invertebrate predators: Induction natural selection
2014/4/16
Aquatic prey species respond to predators with fast (developmental) and slow (selective) feedbacks. Natural selection is assumed to fashion details of induction and to modify baseline morphology, but ...
