Testing a New Passive Acoustic Recording Unit to Monitor Wolves

Posted on October 27, 2020

As part of a broader trial of noninvasive methods to research wild wolves (Canis lupus) in Minnesota, USA, we explored whether wolves could be remotely monitored using a new, inexpensive, remotely deployable, noninvasive, passive acoustic recording device, the AudioMoth. We … read more

Mortality Patterns and Detection Bias from Carcass Data

Posted on June 15, 2019

We developed models and provide computer code to make carcass recovery data more useful to wildlife managers. With these tools, wildlife managers can understand the spatial, temporal (e.g., across time periods, seasons), and demographic patterns in mortality causes from carcass … read more

Unlikely wolf pair sparks row in rural Francetinyurl.com/yc6nwfasA rare discovery in France of a pair of wolves, each from a distinct genetic background, has excited animal lovers demanding their protection and objections from farmers eager to protect livestock.Environmental association Carduelis reported earlier this month it had spotted the pair of wolves, one a male German-Polish wolf -- a species found mostly in western Poland and eastern Germany -- and the other an Italian she-wolf, usually native to the Italian peninsula.While wolf packs typically remain in areas of no more than a few hundred square kilometres (miles), young wolves can travel alone over distances of thousands of kilometres.The French finding, confirmed by authorities, has scientists speculating that a mix of both gene pools could produce a more resilient wolf population."This is a massive stroke of luck," said Carmen Munoz Pastor of the Carduelis association."It will allow a genetic mingling that is always favourable to animal or plant species."Any offspring carrying a genetic crossing of the two different European wolf lineages would be a first in France, Carduelis said.Animal defence association One Voice called for the pair to be protected, including against the so-called "defensive" shooting of wolves.Local authorities have permitted shooting, which they say allows farmers to protect their livestock from wolf attacks."The male wolf has already been injured," said One Voice president Muriel Arnal.Arnal said the two animals were the only wolves on a massive plateau in the Correze department in central France, some 500 kilometres (310 miles) south of Paris."There's room for everybody," she said.Arnal has pleaded with local authorities to ban wolf shooting, recommending the use of guard dogs instead, but to no avail.Some 25 local livestock farmers continue to be authorised to shoot at wolves who they suspect of killing dozens of farm animals every year."It is urgent to stop the threat," local farming associations said in a joint statement. ...

How Wolves Help Safeguard Ecosystems And What We Can Do to Protect Themtinyurl.com/2m3m9rvfWolves are more than just predators. They are a vital species whose presence or absence profoundly impacts the health and structure of their ecosystems.Their predatory behaviors initiate several ecological effects, also known as trophic cascades, which maintain the balance and biodiversity of the surrounding habitats. By preying on large herbivores such as elk and deer, they help regulate the populations, which prevents overgrazing and in turn allows plant communities to thrive.Wolves indirectly boost the numbers of smaller mammals and ground-nesting birds by controlling mesopredator populations such as coyotes. Wolf predation also provides carrion that benefits scavengers such as ravens, eagles, and bears, which enriches the nutrient cycle and supports a more diverse community of organisms throughout the ecosystem.When it comes to ensuring long-term wolf conservation, there must be collaborative efforts between communities and conservationists. Many conservation groups collaborate with ranchers and farmers to implement non-lethal predator deterrents, such as livestock guardian dogs, electric fencing, and range riders. These efforts can reduce human-wolf conflicts, which fosters a sustainable approach rather than lethal control methods. ... See MoreSee Less
