It is always easy to blame an individual species, says Birks.

The identification of certain individual species is often very difficult, even for a specialist in that particular family.

There does not appear to be any threat to individual species from agriculture.

Several of the individual species have a distribution nearly as vast.

In almost all cases the effect is damaging not only to individual species and populations, but also to the natural biological communities.

The Government still tries to protect individual species living in isolated pockets.

New research in Science suggests that face learning may be shaped by the specific ecology of individual species.

This includes at least 50 individual species which are endemic to the area.

Elephants and whales are again the individual species on which this conference focuses.

This does not mean, however, that the individual species representing each type are fixed, and that's the most important thing to remember.
