Global warming link to amphibian decline...(gus might have been introduced. Almo...)

"Almost all of our findings are contrary to the predictions of the chytrid-thermal-optimum hypothesis," said Hudson.

The researchers say their findings show the pitfalls of drawing conclusions from multi-decadal correlations between climatic factors and extinctions, and underscores the need for molecular data on the fungus to understand from where and how it spread.

"We are facing a cataclysmic global decline in amphibians, caused primarily by the effect of a fungus that was historically not important, but the emergence of which might be associated with climate change, along with the use of herbicides and pesticides," Hudson explained. "The bottom line is that there doesn't seem to be one single explanation for the massive amphibian declines. It could be a mix of other factors."
