Who was the first to catalog color? Hint: it wasn’t designers!

Posted 23 Sep 2017 / 0

Pantone color book image courtesy of Carlos Paes via Wikimedia Commons Allison Meier has a very illuminating short piece on where the Pantone color system came from: Hyperallergic “The Bird-Based Color System that Eventually Became Pantone“ What I find interesting about this history is the convergent need of people in vastly different areas of science Read More

“Science: A Candle in the Dark” podcast on Urban Ecology

Posted 18 Feb 2016 / 0

In my search for good podcasts on urban ecology I ran into a real gem in Madhusudan Katti‘s Science: A Candle in the Dark. The podcast is an accompaniment to a science café series that happens monthly in Fresno, California. I love the idea of a science café as a hub of public-academic interaction and a place 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

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

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

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

Is “nest parasitism” really “nest mutualism”?

Posted 20 May 2014 / 0

NPR All Things Considered “This Freeloading Bird Brings Help — And The Help Smells Gross” It is hard to believe that feeding an entire extra non-offspring would be in the self-interest of a bird, but as this short points out, costs and benefits are always environment-specific. In this case, the “parasitic” effect of having to raise Read More

Bird study suggests that multilevel selection theory is necessary to understand population dynamics

Posted 25 Jun 2012 / 0

PLoS One “Multilevel Selection and Neighbourhood Effects from Individual to Metapopulation in a Wild Passerine” I am about to dive into a close reading of this paper, but it suggests that perhaps the reason we do not record multilevel selection pressures is in part because we do not go looking for them.
