Abstract: Large carnivores face serious threats and are experiencing massive declines in their populations and geographic ranges around the world. We highlight how these threats have affected the conservation status and ecological functioning of the 31 largest mammalian carnivores on Earth. Consistent with theory, empirical studies increasingly show that large carnivores have substantial effects on the structure and function of diverse ecosystems. Significant cascading trophic interactions, mediated by their prey or sympatric mesopredators, arise when some of these carnivores are extirpated from or repatriated to ecosystems. Unexpected effects of trophic cascades on various taxa and processes include changes to bird, mammal, invertebrate, and herpetofauna abundance or richness; subsidies to scavengers; altered disease dynamics; carbon sequestration; modified stream morphology; and crop damage. Promoting tolerance and coexistence with large carnivores is a crucial societal challenge that will ultimately determine the fate of Earth’s largest carnivores and all that depends upon them, including humans. - When Big Carnivores Go Down, Even Vegetarians Take The Hit : NPR 011014
Big, fierce animals — lions and tigers and bears, for example — are relatively scarce in nature. That’s normal, because if you have too many, they’ll eat themselves out of prey. But top predators are now so rare that many are in danger of disappearing. That’s creating ripple effects throughout the natural world that scientists are still trying to figure out. Carnivore biologist William Ripple and other "carnivorists" published a study in this week’s issue of the journal Science that lists the benefits that predators provide. They note that in places where predators are reintroduced (such as in Yellowstone National Park), deer and elk — and vegetation — return to a more natural state.
About the Ghost Turtles
150 years after Robert Duncanson painted this luminist scene on the Little Miami River, I stood in the same spot and saw a soft-shelled turtle sunning on a snag. It slipped silently into the water when it heard me. That’s when I knew past is present and destiny, too. That’s when my vision of the Ghost Turtles began. Read more
Ecology of the Senses
Returning to Lake Superior year after year like a migrating loon, I’ve learned the other side of a slow, uncertain process that could be called “going blind.” With the lake as my teacher, I know what lies on the other side. I call it letting go of sight. Read more.Prayer at Big Creek

At the threshold of consciousness, as I slipped back and forth between two worlds, I put my mind in the best place I could imagine, a marsh on Lake Erie called Big Creek. I knew I’d find cranes waiting for me. I cannot say whether I prayed for them, or to them, or with them. The cant of words doesn’t matter. I believe in the still, small voice. I believe what the poet Yehuda Amichai said. Gods come and go. Prayer is eternal. Read moreFreedom to Read

Whenever I hear sanctimonious pronouncements about woke, parental rights, and banning books, I think of Whooping cranes. In my family, the gawky, audacious, elusive and endangered birds are synonymous with our values about the First Amendment and the freedom to read. Read more.Sister, Teacher, Pathfinder
A guidance counselor in high school told my sister Diana, “With your eye problems you will never make it in college. Just forget about it. Get married. Raise a family.” That advice only deepened her determination. She did it all in due time, in her own way –college, marriage, family. She became a guidance counselor herself. She certainly was the most important guide and pathfinder in my life. Read more.Flaneur & Bouquiniste

I remember the book I held in my hands that day. I remember the feel of its time-warped, water-stained pages. I remember its murky, moldy river smell, call it the book’s bouquet, suggesting years of storage on the banks of the Seine. Had I bought it then, I could feel and smell it now and know it from a hundred other books in my library. Read more.R & K: A Rant
