The introduction of Texas pumas to Florida in the 1990s as part of a genetic rescue may have helped save Florida panthers from extinction, but it also brought some harmful mutations with it along the way.<\/p>\n
In a new study led by Âé¶¹Ó³»´«Ã½, researchers show that nearly half of the harmful mutations found in recent Florida panthers came from the introduced Texas pumas, as well as from Central American pumas that were released into Everglades National Park in the 1950s and 1960s.<\/p>\n
The findings, published recently in the Journal of<\/em> Heredity<\/em>, point to the importance of monitoring Florida panther population genetics as well as the need to genetically screen any future introductions.<\/p>\n
The Florida panther\u2019s population reached a dangerously low number of only 30 panthers in the 1970s and 1980s, which led to inbreeding and producing offspring with genetic problems, including heart defects, sexual defects such as cryptorchidism, and other diseases.<\/p>\n
Genetic rescue efforts implemented in the 1990s brought pumas from Texas to Florida to breed with panthers in the Sunshine State. The process is known as genetic admixture.<\/p>\n
The efforts appeared to help, with the Florida panther population rebounding to between 120 and 230 adults, according to estimates from the Florida Fish and Wildlife Conservation Commission, and reports of greater genetic variation now present in the population.<\/p>\n
However, the new findings show this genetic influx had both good and bad mutations with it.<\/p>\n
\u201cThere’s a genetic signal that harmful mutations from different source populations were introduced into the Florida panther population,\u201d says the study\u2019s lead author Alexander Ochoa, a postdoctoral scholar in Âé¶¹Ó³»´«Ã½\u2019s Department of Biology and Genomics and Bioinformatics<\/a> research cluster.<\/p>\n
