The people came from different continents and populations.
"But in the meantime countries and populations will suffer".
No one knows how many; they are secretive, wide-roaming animals, and populations fluctuate each year.
The real challenge is countries with much larger epidemics and populations.
By prohibiting extractive uses, habitats and populations of targeted species can recover from damage and exploitation.

In many other tropical forest regions, as well, resurgent second growth and populations shifts are insignificant.
The edible algae was once part of the diet of Aztecs and populations near lake Chad.
"Libraries already offer an awful lot that supports the wellbeing of communities and populations".
"It's simply the most immediate conservation concern for many species and populations of marine animals".
It is therefore relatively easy to compare urban individuals and populations with their rural counterparts.
