EXCERPTS: Wild countryside had given way to rampant urbanization, and Italy’s central and southern regions—where wolves began recovering first—hosted high numbers of free-ranging dogs. It didn’t take long for the wolves to begin rubbing shoulders (and more) with the local canines.
[...] Lorenzini’s research looked at genetic material collected from 748 wolves that had been found dead between 2020 and 2024, and 26 more that had been collected between 1993 and 2003. The team found that 47 percent were wolf-dog hybrids. And while some of these animals are the descendants of hybridization events that took place generations ago, others are more recent crosses, showing that hybridization is still occurring.
Hybrids are not easy to spot. [...] scientific evidence of these visual differences is lacking and genetic analysis remains the most reliable way to identify a hybrid. But the extremely high presence of wolf-dog hybrids in central and southern Italy, Ciucci says, represents a threat to the future of the country’s wolves.
It’s unlikely that a wolf living in a healthy, stable pack in the wild would reproduce with a free ranging dog, Ciucci explains. Those wolves are more likely to see a dog as competition, or even as prey. But when the pack structure falls apart and female wolves find themselves alone in an area filled with free-ranging dogs, the dynamic can change.
[...] the fact that so many are actually dog hybrids poses a silent danger, Ciucci says. Italy’s wolves might be close to a point of no return that experts call “genetic swamping,” in which the wolves’ original gene pool is irreversibly replaced by the hybrids’. In simple words, it means the wolf—genetically speaking—could disappear.
[...] Wolves can cross vast distances, and hybrids could eventually mix and mingle with wolves in northern Italy, or even across Europe.
Of course, wolves and domesticated dogs have been breeding—and thus hybridizing—since they first diverged thousands of years ago. In North America, for example, gray wolves with black coloring are believed to be the distant descendants of wolf-dog mixes. Research suggests these canines even picked up some perks from their interspecies mingling. Black wolves are in fact more resistant than their peers to some diseases such as canine distemper, and may also be more successful at hunting in forests.
But what’s happening in Italy is totally different, Lorenzini says, because of the scale and the speed at which it is taking place... (MORE - missing details)
