Special Sea Slug Poised to Make a Comeback Off California

Mar. 18, 2013 — After almost four decades of absence from local waters, a special sea slug appears to be making a comeback, and marine scientists at UC Santa Barbara are eagerly anticipating its return.

With its vivid blue and gold colors and its discovery by UC zoologists in 1901, the nudibranch Felimare californiensis, also known as the California chromodorid, has been a favorite species of sea slug for UC marine scientists and students for decades. But while it held a special place in their hearts, it lost its place in local waters, which once included La Jolla, Corona del Mar, Malibu, and Santa Barbara, as well as all but the two westernmost Channel Islands.

"We'll be pretty excited if someone finds the nudibranch in mainland tidepools, after this 35-year hiatus," said Jeff Goddard, project scientist with UCSB's Marine Science Institute. His findings have been published online in a recent edition of the journal Marine Biology.

In the 1970's, the abundant F. californiensis started to disappear from Southern California, and by 1984, was extinct in the region. Its disappearance from the mainland, said Goddard, is unique among the 130 species of sea slugs known to inhabit California waters.

Pakistan's National Mammal Makes Comeback

ScienceDaily (July 3, 2012) — The Wildlife Conservation Society (WCS) announced July 3 that the markhor -- a majestic wild goat species -- is making a remarkable comeback in Pakistan due to conservation efforts.

WCS-led community surveys have revealed that markhor populations in northern Pakistan's Kargah region in Gilgit-Baltistan have increased from a low of approximately 40-50 individuals in 1991 to roughly 300 this year. These community surveys suggest that the total markhor population where WCS works in Gilgit-Baltistan may now be as high as 1,500 animals, a dramatic increase since the last government estimate of less than 1,000 in 1999.

Pakistan's national mammal, markhor are known for their spectacular, corkscrew horns that can reach nearly five feet in length. They are an important prey species for large carnivores such as wolves and snow leopards. Markhor have been listed as Endangered by IUCN since 1994, with a 2008 global population estimate of less than 2,500 animals across five countries: Pakistan, Afghanistan, Tajikistan, Uzbekistan, and India. They are threatened by illegal hunting, habitat destruction, and competition from domestic goats and sheep.
