I saw a documentary recently about the conservation challenge of non-photogenic endangered species, such as the Dominican Chicken (a big frog with tasty legs) which are on the verge of being wiped out (in the case of the Chicken, by over-hunting and an infectious fungus that was probably brought in by a tourist). It's strange--amphibians have been around for millions and millions of years, and even this particular species has been around for ages, but they are so very specifically adapted to their habitats that they're two degrees from extinction at the best of times (well, at least since the industrial revolution). I guess when you have a fairly permeable skin layer protected by a rather pH specific mucus, the slightest environmental change can wreck your defences and cause catastrophe. Like the white perch in Baltimore Harbour--almost all of them have an intestinal infection (that starts at the anus) by midsummer because the bay's acidity changes during fertilizer season, burning through their protective layer right when the algal bloom is reaching its peak. This illness, plus depleted dissolved oxygen levels (courtesy of the opaque slurry of dead algae) prevents many of these little ugly fish from reaching sexual maturity, so spawn counts are lower, which means the animals that eat them are going hungry...but they're not big or fluffy, so no one really cares. Holistic ecology is lost on most people.
