Fishing For Dollars  

Conservation Magazine, among others, is reporting about a study recently published in PLoS Biology that concluded that river basins most invaded by non-native fish species tend to be located in parts of the world where the greatest amount of human activity occurs. The authors found a positive correlation between level of invasion and such factors as Gross Domestic Product and population level, but did not see significant correlation when looking at biotic factors like number of native species in the invaded ecosystem. Perhaps more worrisome is that these invasion "hotspots" are the same places where the highest numbers of threatened native fish species live.

This story is getting additional coverage here, here and here, but if you want the whole story, you should go read the full article (it's free!). Thanks to budak for sending in the link.
