Episode description
Long time zoological statistician and animal manager, Kevin Willis, returns to discuss dolphin demographics and other mathematical insights into current species populations in human care. The overall population of dolphins in facilities looks promising, but Kevin warns this view is not reality since the animals are not actually maintained as one but several small islands of sub-populations that are not at all sustainable as currently managed. He also argues that zoos and aquariums are in the midst of change from the Noah's Ark conservation model of the 1980s and its SSP's (Species Survival Plans) designed to one day re-populate wild habitats, once humans get their act together, to something as yet still evolving. In fact, the number of managed species has been greatly reduced and the word conservation no longer appears in the description of SSP's on the Association of Zoos and Aquariums (AZA) website. When asked what the math tells him about the future of species and genetic diversity of both plants and animals in zoos and aquariums and the wild, he shares that we as a community have some tough choices ahead about what species can and should be prioritized for preservation.
