After near extinction, new genome data bodes well for condors' future

The once-abundant California condor briefly went extinct in the wild, with only 22 individuals living in captivity by 1982. Today, 300 condors live freely in the wild and another 200 are in captivity. But, despite the condor s struggles, a new study of the California condor genome reported in the journal
Current Biology on May 13 has found a surprising amount of genetic diversity.
The study is the first to begin quantifying diversity across the entire California condor genome, which offers researchers needed baseline information to inform future research and conservation of this iconic species, the largest species of land bird in North America. The researchers say that the quality of their genome assembly is among the highest for any bird genome sequenced to date. ....

Despite numbering only a few hundred individuals, Californian condors have retained a surprisingly high degree of genetic diversity, a new study said Thursday.
The authors of the paper, published in the journal Current Biology, said the findings bode well for future restoration plans of the critically endangered species.

High genomic diversity is good news for California condor

Despite having been driven nearly to extinction, the California condor has a high degree of genetic diversity that bodes well for its long-term survival, according to a new analysis by University of California researchers.
Nearly 40 years ago, the state s wild condor population was down to a perilous 22. That led to inbreeding that could have jeopardized the population s health and narrowed the bird s genetic diversity, which can reduce its ability to adapt to changing environmental conditions.
In comparing the complete genomes of two California condors with those of an Andean condor and a turkey vulture, UC San Francisco and UC Berkeley scientists did find genetic evidence of inbreeding over the past few centuries, but, overall, a wealth of diversity across most of the genome. ....
