Wolves appear capable of escaping competitive exclusion from tigers only when human pressure decreases tiger numbers.

The chicks take up these microbes and are not colonized by harmful salmonella, an effect called competitive exclusion.

Therefore there was no evidence for competitive exclusion or co-occurrence between any two parasites.

Niche differentiation is a process by which competitive exclusion leads to differences in resource use.

Although local extinction of one or more competitors has been less documented than niche separation or competitive exclusion, it does occur.

Niche separation of species, local extinction and competitive exclusion are only some of the possible effects.

The segregation of black bear and grizzly bear populations is possibly due to competitive exclusion.

Recent studies addressing some of the assumptions made for the models predicting competitive exclusion have shown these assumptions need to be reconsidered.

Tigers have been known to suppress wolf populations in areas where the two species coexist, mainly via competitive exclusion.

If we choose to only follow the path of competitive exclusion and exploitation, we'll end up a world of Stalins.
