Urban Wildlife Podcast on synanthropes and urban island castaways

Posted 06 Oct 2015 / 0

Urban Wildlife Podcast “Episode 3: Timbers on a Boston Island” I love this episode because it captures the two major human impacts of urban ecology: the creation of commensal niches for some species while other species are isolated to islands of small remaining habitat. We learn about a variety of organisms from birds to bugs Read More

Should we compromise with nations that hunt whales?

Posted 06 Oct 2015 / 0

Frontiers in Ecology and Evolution “A deal with Japan on whaling?” Having been a fan of Whale Wars for awhile, and being predisposed to thinking that we ought to protect large, social, cooperative, cognitively-advanced animals, it is a bit hard for me to accept legal whaling of any kind. But as this article points out Read More

Are big corporate polluters trying to “artwash” their image?

Posted 29 Sep 2015 / 0

The Guardian “Activists occupy British Museum over BP sponsorship” I really like that idea expressed by these activists that BP’s sponsorship of big art exhibits is not philanthropy. They are basically paying to mainstream their own presence, to obscure their true identity as a corporation that profits from threatening the future of our species. A Read More

Go mutualistic or go home?

Posted 15 Aug 2015 / 0

The Chronicle of Higher Education “The Great Extinction” I agree with this article’s overall perspective, which is that it is a bit weird to view humans as unnatural. What we are is unprecedented as a single species that defines a geologic time period (albeit what is likely to be a very short one). I also Read More

Sadly, the Population Bombers (mostly) still don’t get it

WNYC The Leonard Lopate Show “Is Human Overpopulation The Reason for Environmental Destruction?” In my Ecology for Architects class we do an activity (“Perspectives on Becoming Ecologically Sustainable“) that challenges my students to comprehensively consider our large-scale options for becoming sustainable. When we do the activity we have already done some ecological footprinting and discussed Read More

New article in Science provides a comprehensive overview and update on Yellowstone National Park

Posted 24 Apr 2015 / 0

Since I began teaching Ecology at Pratt, I have used the re-introduction of wolves to Yellowstone as the cornerstone case study of my community ecology lessons. Using material originally developed by my colleague Damon Chaky for the Ecology for Architects course, I ask my students to use ecological theory to explain some of the changes that Read More

Evolution 2014: Could the right symbionts provide protection from chytrid infection to amphibians?

Posted 21 Jun 2014 / 0

Patrick McLaughlin showed work on Bioko Island suggesting that frogs there may be protected from the ill effects of chytrid infection by the presence of bacterial symbionts. These symbionts produce metabolites that lower rates of parasitic infection, suggesting that symbionts might be used to protect amphibian populations worldwide. It also suggests a mechanism by which Read More

EnviroAtlas is now live, publicly available

Posted 30 May 2014 / 0

For the past couple of years I have been playing around with a really cool tool called EnviroAtlas, a project of the U.S. Environmental Protection Agency. This past semester I created two classroom activities that use EnviroAtlas, implementing them for the first time in my Ecology for Architects course. The EnviroAtlas tool was in beta-testing Read More

Our review paper on Late Pleistocene Extinction Modeling published in QRB!

Posted 21 May 2014 / 0

I am proud to announce that a paper on which I am co-author, “A review and synthesis of late Pleistocene extinction modeling: Progress delayed by mismatches between ecological realism, interpretation, and methodological transparency“, has been published in the June 2014 issue of The Quarterly Review of Biology. The paper looks at the history of modeling aimed Read More

Understanding the cascading effect of carnivore loss… before we lose all the carnivores

Posted 25 Jan 2014 / 0

NPR Morning Edition “When Big Carnivores Go Down, Even Vegetarians Take The Hit” Science “Status and Ecological Effects of the World’s Largest Carnivores” Both of these articles are great for introducing the idea of trophic cascades as well as how trophic inefficiency implies that large predators require large ranges containing abundant prey.
