Urban Wildlife Podcast on Cats and Coyotes

Posted 20 Sep 2015 / 0

Urban Wildlife Podcast “Episode 4: Cats and Coyotes” What I really enjoyed about this particular episode of the Urban Wildlife Podcast was the interaction between topics covered. The effects of both cats and coyotes are still largely unknown, even as both animals are fairly common in urban areas. Domesticated cats are pretty easy to track Read More

Can good design make highways less of a problem?

Posted 08 Sep 2015 / 0

Scientific American News Feed “California Officials Unveil Plans for Wildlife Bridge over Highway” In my Ecology for Architects class we talk a lot about Mountain Lions and how their habitats are fragmented by highways. Radio collar and mortality data suggests that these urban predators need better corridors across highways. Could this grassy bridge be a Read More

Carrying capacity — but not growth rate — varies with habitat quality (at least for moose)

Posted 17 Aug 2015 / 0

Ecosphere “Characterizing demographic parameters across environmental gradients: a case study with Ontario moose (Alces alces)” What I find interesting about this study — besides its unprecedented investigation of something that would seem pretty critical to basic conservation efforts — is what was and was not intuitive in its findings. Moose have higher carrying capacities where 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

So much for the big-brained city bird theory?

Posted 05 Aug 2015 / 0

BMC Ecology “Commonness and ecology, but not bigger brains, predict urban living in birds” What makes this study smart is that it compares the birds that live successfully in urban areas with the birds that actually have the potential to colonize cities. This makes for a much more meaningful comparison than simply comparing urban species Read More

Rivers, Lakes, Seas, and Environmental Justice

Posted 22 Jul 2015 / 0

National Geographic “Sins of the Aral Sea” National Geographic “Last Rites for the Jade Sea?” These recent National Geographic issues both feature articles on threatened bodies of water and the role that over-exploitation of feeder rivers plays in these threats. In both the case of the Aral Sea, which has already been largely ‘disappeared’ by 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

Court Ruling in the Netherlands may point the way to cracking the climate compliance conundrum

Posted 24 Jun 2015 / 0

BBC News “Climate change: Is the Dutch court ruling ‘a game changer’?” Nature Breaking News “Landmark court ruling tells Dutch government to do more on climate change” The New York Times “Landmark Dutch Ruling: Cut Emissions to Protect Citizens” The Guardian “Dutch government ordered to cut carbon emissions in landmark ruling” There is so much Read More

Is the threat of regulation enough to incentivize cooperation from nitrogen polluters?

Posted 01 Jun 2015 / 0

National Public Radio All Things Considered “It’s Raining Nitrogen In A Colorado Park. Farmers Can Help Make It Stop” What I find interesting about this example is how the local nature of this problem creates greater incentives for “voluntary” measures taken by polluters to reduce the impacts of their polluting activities. Because the effects of Read More

In the end, climate compromise comes down to writing and editing

Posted 01 Jun 2015 / 0

National Public Radio Morning Edition “Editing The Climate Talkers: Punctuation’s Effect On Earth’s Fate” I would suggest that the future of human civilization depends on reaching an international agreement to put a halt to — and partially reverse — anthropogenic climate change. Although the history of climate change agreements is pretty fraught, it does appear Read More
