Louisiana researchers have identified 14 new species of shrews, a relative of hedgehogs and moles, on an Indonesian island. It’s been 90 years since this many new species were named in one paper.
It’s been 90 years since this many new species were identified in one paper, Esselstyn said. The 1931 paper by George Henry Hamilton Tate identified 26 possible new species of South American marsupials, but 12 were later found not to be separate species for a total of 14 new ones, he said.
At the start, he was hoping to clarify how the six species then known in the genus Crocidura had developed. “I was interested in questions about how shrews interacted with their environment, with each other, how local communities were formed,” he said.“It was overwhelming because for the first several years, we couldn’t figure out how many species there were,” he said.
For this paper, they examined 1,368 shrews, more than 90% of them collected by Esselstyn’s group, which trapped the animals on a dozen mountain sites and two in the lowlands of Sulawesi. Researchers have found at least seven such zones — roughly, the island’s central mass, the three “legs” of the k, and three zones on the long bent neck.
