Darwin's Frog (Rhinoderma darwinii), FMNH no. 40125 and others. Field Museum of Natural History, Chicago. Conservation status: vulnerable. Occurring in the forests of Argentina and Chile, this species suffers from habitat loss and possibly chytridiomycosis, a fungal disease that affects many amphibians. In the northern part of its range, deforestation and replacement of native trees with pine and eucalyptus monocultures. In its southern range, clearcutting is the primary cause of decline. Other contributing factors of decline for Darwin's Frog and many other amphibians are climate change and increased exposure to ultaviolet radiation.

As biologists describe new species and add to our understanding of the interrelated nature of life on Earth, a species becomes extinct every 20 minutes (100 to 1000 times the background extinction rate as seen in the fossil record). Collections in natural history museums play important roles in conservation, education and research. Most of that work and the associated specimens are not on public display in museumsâ typically, less than five percent of specimens are exhibited.
