Vertebrate biodiversity– a glimmer of hope


Vertebrate populations – from birds and fish to antelope – are not, in general, declining. Despite what has previously been thought and said.

A McGill University-led team of biologists found, in an article published today in Nature, that the picture of dramatically declining vertebrate populations of all kinds is driven by a small number of outlier populations whose numbers are dropping at extreme rates. Once these outliers are separated from the mix, a very different and far more hopeful picture of global biodiversity emerges.

(Populations are groups of individuals of the same species living in a particular area, and therefore decreases in population size will precede loss of species.) MORE
