Meandering musings about the natural world: ecology, evolution and our environment. (Some science posts, some wild nature conservation posts.) My research-based posts tend to be about natural history, ecology and conservation biology.

Electrifying deterrents: wolves and fladry
by DeLene Beeland in Wild Muse
Fladry has proved to be an interesting and rather low-tech tool to ward wolves away from domestic livestock in certain conditions. It consists of red flags or pennants attached to a piece of twine or thin rope at regular intervals (about 18 inches or so) and strung around a livestock corral or pen. Like all [...]... Read more »

Anti-carnivore alliances as community symbols
by DeLene Beeland in Wild Muse
When wolves and livestock, or pets, come into conflict with each other, people’s tolerance for wolves on the landscape tends to decrease. Part of the problem is the economic loss to the livestock producer, so some predator conservation organizations offer compensation payments for wolf-killed livestock as a tool to increase tolerance for wolves. Additional reasons [...]... Read more »

Africa’s new, old gray wolf
by DeLene Beeland in Wild Muse
Africa has a new, old wolf. An animal that was previously called a subspecies of the golden jackal in Egypt has now been found to be a very rare relict species hiding in plain sight — an ancient gray wolf line still living today. Previously, it was thought that the Ethiopian wolf (Canis simensis) was [...]... Read more »

What does a positive-incentive carnivore compensation program look like?
by DeLene Beeland in Wild Muse
It was October 2007, and I was half-living out of my car while circumnavigating the 6,845-square mile Mexican gray wolf reintroduction area straddling New Mexico and Arizona. I was interviewing stakeholders in the wolf reintroduction project for my master’s thesis. Short on cash, I was camping out and couch-surfing for the two months my project [...]... Read more »

Coastal northwest American marten conservation
by DeLene Beeland in Wild Muse
Just how many sub-species of American martens are living in California and Oregon? Well, there may be one less than experts thought, according to a 2009 study published in Conservation Genetics. American martens (Martes americana) are slightly larger than a house cat and are carnivorous members of the Mustelid family. They live in boreal forests [...]... Read more »

The BIG picture: Ecological effectiveness
by DeLene Beeland in Wild Muse
In an age when endangered species are often recovered just as much by force of legislation, á la the Endangered Species Act, as they are by scientific principles, I often find myself weighing the Big Picture of ecological effectiveness against the minutae of things like genes and mere numbers. Let me explain. I’m not knocking [...]... Read more »

Stressed out cattle and elk?
by DeLene Beeland in Wild Muse
Can the mere presence of a wolf stress a prey animal so much that they lose weight? New research says, Yes, maybe so. When I was working on my master’s, I interviewed several cattle ranchers in the Southwest — namely, Arizona and New Mexico. I was looking for their beliefs and opinions about Mexican wolf [...]...

Putting a number on it: Maned wolf survival rates
by DeLene Beeland in Wild Muse
How can you conserve a large carnivore when you don’t know how many of them exist? It’s a difficult task, and so a few scientists at the Jaguar Conservation Fund opted to put a number on their target population… only it’s not jaguars they were trying to pinpoint, it was the lesser known maned wolf.

Warming caves: A stop-gap prevention to thwart white-nose syndrome?
by DeLene Beeland in Wild Muse
I’ve been trying to tune into developments with white-nose syndrome because it’s one of the worst emerging pathogens to hit North American wildlife in recent history. Ever since the first breakout in a New York cave in February 2006, this white fungus has killed off well more than a million bats from six different species. [...]... Read more »

A new take on necking (in giraffes, that is)

Y’all menfolk will do some wacky stuff for sex, that is fo’ sure. (I get to say “y’all” with authority because I grew up in the South. Honest.) And so it goes in the animal kingdom too.

Endpoint of overfishing is now in sight: Firth of Clyde
by DeLene Beeland in Wild Muse
Seems like any time I read about ecology studies lately, its tales of waste and wanton destruction. And a recent paper in PLoS-One about “Ecological Meltdown in the Firth of Clyde, Scotland” was no different. Sigh. May as well have titled this post “Why we need Hands-Off conservation approaches.” The paper describes commercial fishing in the [...]... Read more »

How much for that tiger skin?: Modeling illegal wildlife trade markets
by DeLene Beeland in Wild Muse
While a lot of attention is paid to reporting on human warfare across the globe, the illegal war on wildlife that is carried out through trafficking, poaching, and bush meat trades is often given comparatively less coverage. (At least in U.S. mainstream media, to which I refer here.) I’ve been starting to pay more attention [...]... Read more »

Bedeviled Tasmanian devils
by DeLene Beeland in Wild Muse
Wild Muse just perused the latest issue of Conservation Biology and went foraging for substantive research to post about… Hold on tight because we are going to Tasmania.

More hybrid lovin’: coywolves, wolves and coyotes…
by DeLene Beeland in Wild Muse
Is it a wolf? No. A coyote? No. A mixture of the two? Oh, yes. Northeastern wild canids have been leading biologists on a wild goose chase recently, as science scrambles to catch up with just what, exactly, Mother Nature has been cooking up in Massachusetts. Reports of extra large eastern coyotes have been rolling [...]... Read more »

The wolves of Ethiopia
by DeLene Beeland in Wild Muse
When most people hear the word “wolf,” they think of the burly gray wolves of the Great White North. But wolves are present all over the world, even in Africa. The Ethiopian wolf, Canis simensisis incredibly endangered. As its name implies, it lives in Ethiopia, but it lives only in seven highland mountain ranges, above [...]... Read more »

Givin’ props to hybrids
by DeLene Beeland in Wild Muse
Why does the lay public tend to view hybridization in wild nature as a bastardization of the way things ought to be? Why do we favor “pure” species while rejecting hybrid crosses, or treating them like side-show freaks á la pizzlies, ligers and tiglons? I’ve been thinking a lot about hybridization lately, trying to wrap my head around [...]... Read more »

Mesopredators gone wild
by DeLene Beeland in Wild Muse
Are we headed toward a world full of foxes, skunks and raccoons — but empty of lions, tigers and bears? Maybe. It’s a fact that many of the planet’s large carnivores are in dire straits. Where I live in the eastern U.S., we no longer have cougars or eastern wolves, top predators that used to [...]... Read more »

Biodiversity, globalization and shifting disease ecologies
by DeLene Beeland in Wild Muse
As I was researching a story for the Observer, I had to go poking through the December 2009 issue of BioScience, and I stumbled across an interesting article reviewing biodiversity declines and global disease ecology. The authors assert that multiple factors working synergistically are leaving humans more at risk of contracting infectious diseases — [...]... Read more »

Begging meerkat pups
by DeLene Beeland in Wild Muse
Learning about animal behavior never fails to fascinate me, and so it was with great interest that I read a recent paper on how meerkat pups alter their food-begging behavior depending upon the adult meerkat that they are nearest to. {1} Not all adults are created equal, it seems, in the world of a [...]...

Adaptive radiation of “coywolves”
by DeLene Beeland in Wild Muse
Lately, “coywolves” have been making headlines and raising eyebrows. They are a wild canid that is a hybrid between a coyote and a wolf. It may sound like an urban legend, but coywolves are real.* I first learned about this quirky common name via a news article from The Star in Canada, Meet the Coywolf [...]... Read more »
