The Florida panthers may be saved. They simply needed a little Lone Star assist.
Fifteen years ago the big cats in Florida were in dire straits, doomed to probable extinction because of genetic inbreeding and dwindling numbers. Now, though, their population is on the upswing, thanks to a program that brought in eight females from a panther population in Texas to bolster the Florida cats. Scientists who studied the experiment report in the journal Science that it has worked: Both the numbers and the genetic diversity of Florida panthers improved drastically.
Hybrids of the Florida cats and cousins of the same species from a wild-caught Texas population have twice the genetic variety and far fewer of the genetic defects that were known in Floridian panthers before the introduction, says geneticist [and study coauthor] Warren Johnson. [Science News]
