This one Talks about the spread of Batrachochytrium dendrobatidis a fungal pathogen in frogs, that has been of tremendous concern to scientists lately, especially because it may herald the extinction of many tropical species.

And this one is about the Allelopathic behavior of some seaweeds and how they cause coral bleeching. To my mind this is hinting that global warming may not be hurting the reefs as much as thought, but that overfishing and the direct effects of CO2 on Algal growth may be enough to explain much of the devastation on their own.

Just click on the little links that say Full Text (PDF) to read more, If something doesn't make sense or you don't know a word just ask, and I'll do my best to explain it.
