WmD Episode #00003 has been released

Posted 20 Aug 2015 / 0

The WmD Project is picking up steam!  This week I have released the third episode of WmD’s video blog: You can see this episode in its ‘native habitat’ here. The first season of WmD is dedicated to the “big questions in ecology and evolution“. This episode, “Difference is as difference does”, is meant to cover these questions: Why do 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

WmD Episode #00002 has been released

Posted 07 Aug 2015 / 0

It took me a lot longer than I would have wished, but I have released the second episode of WmD’s video blog: You can see this episode in its ‘native habitat’ here. The first season of WmD is dedicated to the “big questions in ecology and evolution“. This episode, “Keep on keeping on… until you 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

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

Urban tree power

Posted 17 Jul 2015 / 0

I am not much of an arborist (well, really, I am not an arborist at all!), but I do appreciate trees. Urban trees are especially interesting to me because of their ability to deal with the many insults of the urban environment. I thought that this image — taken where the curb had been peeled Read More

My new favorite concept mapping activity: depicting whole-system ecological flows

Posted 17 Jul 2015 / 0

Concept mapping is increasingly becoming an important part of my overall approach to teaching. I started out using it in my own research, and quickly realized how valuable it can be as a teaching tool. Because the only real goal of making a concept map is to explore and express understanding of a topic, concept Read More

Evolution beyond adaptation: a critical step for evolutionary theory

Posted 04 Jul 2015 / 0

The July 2015 issue of Trends in Ecology & Evolution features a really important review article entitled “Selection on stability across ecological scales“. The paper embraces the idea that the stability properties of ecological systems dictate the configuration of extant social groups, interacting species pairs, and overall ecological communities. Lev Ginzburg, my Ph.D. advisor, has Read More
