Sentences with phrase «few viable populations»

Not exact matches

Furthermore, the researchers suspect that even if habitat destruction were to halt in these areas, the remaining large animal species would have little chance of maintaining viable populations beyond the next few decades.

The abrupt impact of climate change on causing extinctions of key concern, therefore, is its potential to deplete population sizes below viable thresholds within just the next few decades, whether or not the last individual of a species actually dies.

These considerations make it very likely that at least some populations and species would likely go extinct, and even more will likely drop below viable numbers of individuals within the next few decades simply because they could not disperse across fragmented landscapes fast enough to keep pace with movement of their required climate zones.
