Lev Ginzburg Fest: celebration of a “retirement”

Posted 17 Dec 2015 / 0

“Lev Ginzburg has retired”. For anyone who knows Lev, this combination of words does not make a whole lot of sense. Is it possible that such a lively and active scientist would hang up his yellow pad and pencil in order to put his feet up in some retirement community far away from the world Read More

Mist net photographs as art?

Posted 16 Oct 2015 / 0

Image Source: Scientific American Scientific American Symbiartic “The Complex Net of Human Interference” Mist netting is a common tool of the ornithologist: you set up thin, nearly-invisible nets in areas where birds travel and wait to see who gets caught. These images capture the diverse beauty of these birds at the moment of their capture. Read More

Charismatic megafauna offer protection to their less appealing heterospecifics

Posted 16 Oct 2015 / 0

Conservation Magazine “Pandas offer ‘protective umbrella’ to other animals” In my ecology courses we talk a lot about the different rationales for conservation, and students invariably laugh at the concept of charismatic megafauna. It is kind of weird — and very typically human — that we reserve particular conservation attention for those big animals that 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

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

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

Urban Wildlife Podcast on big animals in big cities

Posted 27 Jul 2015 / 0

Urban Wildlife Podcast “Bangkok Pythons and Gotham Whales” This is a really interesting podcast that focuses on the wildlife of cities. This episode is about huge animals that manage to live in close proximity to cities, specifically in their waterways. The section on reticulated pythons — which can grow up to 23-25 feet long — 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
