Hope for frog conservation got bleaker with a recent study showing that fungus-associated extinction is reducing amphibian biodiversity in Central America

Species such as the red-eyed tree frog (Agalychnis callidryas), pictured here, seem to be relatively abundant despite the presence of the disease. In contrast, rarer species were more likely to disappear, leading to loss of frog biodiversity across the region. [Less] [Link to this slide]

The banded horned tree frog (Hemiphractus fasciatus), pictured here, became extinct at all three of the sites where they were detected prior to chytrid's arrival. As the fungus spreads southeast through Central America, at a rate of tens of kilometers per year, the authors fear that it will continue to destroy H. fasciatus populations. The loss of these amphibians means an ecological loss, not to mention the extinction of unusual triangular-headed frogs that carry their eggs on their backs. "We're losing the really cool stuff," says Lips, who has spent two decades surveying frog communities in Central America. [Less] [Link to this slide]
The lemur leaf frog ( Hylomantis lemur ), pictured here, disappeared from all of the sites that Lips surveyed. H. lemur lives in moist areas where the chytrid-causing fungus thrives....[More]

Then some scientists told me 80-90% of plants on earth, are dependent on fungi to propogate their seeds and spores.
Maybe if you change the eating habit of little frog
it may be an experiment.
Meaning that fungus related problem are directly related to
the frogs eating habits.
Other species may be at threat because of this
fungi-plant-leave propagation syndrome.
Easy experiments: Remove food that is fungi propagated in this cute little frog.

I think about these little creatures. They would be

Then the little frogs eat insects. It is called the
food-chain in science.
So there are toxics in the leaves that the insects eat.
Through evolution turns this into fatal toxics for
the insect predetors -- cute little frogs.
We do not like to see this because of the beauty and
cuteness of the little frogs.
Yet in evolution -- the insects who may be very ugly have to
fight for their position in the food-chain too.
I as hobby scientist think the food chain is the little
frogs problem.
This is basic medicine: In the mouth nose and ears
and out the BT.
Are these vegitarian frogs? Maybe the insects are
winning the evolutionary dialetric.
