Red wolf, Barron Crawford/Fish and Wildlife Service

Wild Muse has been terribly quiet lately. If you think that means something is up behind the scenes around here… you’re right! I’m stuck in Book Revision Land for the next month or so. But I made time last week to write about a timely wildlife management issue in my state. The NC Wildlife Resources Commission has proposed allowing the night-hunting of coyotes with artificial lights state-wide, with no bag limit, no season, and no permit required. The weirdest part? To the untrained eye, coyotes and federally-endangered red wolves are hard to tell apart in the daytime, much less at night. What will this proposal mean for red wolves? Read more in my in-depth report on the Scientific American Guest Blog.

It’s been exactly six months since I posted on Wild Muse. What have I been up to since then? I finished my first non-fiction book! (No, really! It’s done!) It’s tentatively titled The Secret World of Red Wolves: A True Story of North America’s Other Wolf. Writing this book is a singular accomplishment in my life. If you’ve read this blog, you’re probably familiar with the book’s topic. But if you’re not familiar, then here’s a quick recap: it’s a story of the red wolf, Canis rufus, which is a predator that used to live throughout the central and southeastern United States. It’s a contested species, and its taxonomy has been elusive. Some people don’t believe it’s a wolf at all. Others believe it opens a window to a lineage of wolves that evolved solely in North America. If you’re opening another browser tab to look it up on Wikipedia, take the entry with a grain of salt, it needs improvement and the sections on its taxonomy and origins appear to be largely authored by the camp of people who disbelieve the animal is a distinct entity, without much coverage of opposing views. In the book, I cover the full spectrum of these views, in the context of how our understanding of these animals has changed as science uncovers new clues to their past origins.

Oddly, a modern detailed treatment of the red wolf’s whole story has not been told all in one place before for a general audience. The idea for this book came to me after I moved to North Carolina in late 2008. The Old North State is home to the only wild population of red wolves in the world. They have been reintroduced to the eastern part of the state, in a coastal area known locally as the Albemarle peninsula. When I moved, I knew from my previous research on Mexican gray wolves that a red wolf program was underway in North Carolina, but that was about the extent of my knowledge. In my literature review of Mexican wolves, I’d also bumped up against several papers on red wolves for which I read the abstracts but didn’t have time to read more. I filed them away for investigation at a later time, but they left me with the lingering impression that there was something controversial about the red wolf’s origins and our current understanding of its genetics.

When I finally had some free time, I searched for an in-depth non-academic book to learn about red wolves, but I was surprised I could not find a current one. The most recent one for general audiences is actually a section of a book from 1993— and believe me, a lot has transpired since then. Other recent books were written for children, or were fairly superficial and did not address any of the evolutionary origin or genetic debates that I knew had cropped up about red wolves since the mid-1990s. Writings that addessed the red wolf’s genetics and taxonomy were relegated to academic chapters within other works, and scientific papers. Without truly understanding what I was getting myself into, I began to form the idea that perhaps I should write a current book about red wolves. Afterall, I love learning about predator ecology and conservation. What could go wrong? (Well, for one thing, I didn’t know how to write a book!)

After a few months of research, I wrote a book proposal and sent it to a few university presses. The University of North Carolina Press accepted it in November of 2009. (more…)

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 genetic diversity by any means, it’s just that genes and population size aren’t the only things we need to consider when recovering imperiled species. And yet, these are often the elements that we get so caught up on, almost myopically. As readers of Wild Muse know, I often think a lot about wolves and large mammalian predators. And when it comes to recovery of species that have been exterminated — or pushed out of — most of their range, you inevitably run into issues of genetic diversity and how many of these imperiled animals are where. Which is important and has a prominent place in species recovery arguments.

But what about species that create strong interactions among other species in the communities within which they make a living? Does recovering X-number of them in Y-populations truly = recovery? For example, if Montana has 300 gray wolves and 10 breeding pairs within their state lines at all times, can we really walk away from this and say that gray wolves in Montana are recovered? Legally, yes — they would be. But ecologically, we know this would not be true. (more…)
