This makes it difficult to realise the potential of rye in disease resistance and ecological adaptation.

The differences between species are ecological adaptations to different environments in relatively dry or wet climates.

In practice though, their ecological adaptation is for the adults to scavenge and hunt on the water surface, so they seldom stay down for long.

Mediterranean vegetation shows a variety of ecological adaptations to hot and dry summer conditions.

The differences are ecological adaptations to different environments over a relatively dry-wet climate.

Not all social features of a species need be direct expressions of ecological adaptation, however.

They reproduce via direct development, an ecological and evolutionary adaptation that has allowed them to be completely independent from free-standing water.

Each species selects the situation of the water into which it lays its eggs and does so according to its own ecological adaptations.

Her research interests also include comparative slavery, human ecological adaptation, and the roles of women in patrilineal societies.

It is uncertain whether this presence of biliverdin is an ecological or physiological adaptation of any kind.
