ECOmotion Studios on Hairston Smith Slobodkin and why the earth is green

Posted 06 Oct 2015 / 0

Here’s another fun and informative video from ECOmotion Studios. I thought that it was interesting how this short discussed the connection between decomposers and the eventual supply of oil, although I wonder if many viewers will gain enough information from this short video to fully understand this idea. The basic ideas behind Hairston-Smith-Slobodkin (HSS) are Read More

EcoMotion studios celebrates Robert Paine’s Pisaster experiments

Posted 06 Oct 2015 / 0

Back at the Evolution 2014 meeting I encountered the great “Drift” animated short, which I still use in my evolution course. Well the producers of that short have formed ECOmotion Studios, and they have made a bunch more videos in honor of the Ecological Society of America‘s centennial. This one is a fun “spoken word” jam 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

Like-with-like assortment plus exponential fitness increases cooperation, even under weak selection

Posted 06 Oct 2015 / 0

arXiv “Assortment and the evolution of cooperation in a Moran process with exponential fitness” I am still struggling to understand when it would be appropriate to assume an exponential (rather than linear) fitness function. It is wonderful that these modelers are mapping out all these different conditions under which cooperation evolves, but how to select 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

The often-large difference between “breeding” and “parenting”

Posted 02 Oct 2015 / 0

WNYC The Leonard Lopate Show “Options Grow For Starting a Non-Traditional Family” As I continue to work on my popular science book with the working title Breeders, Propagators, & Creators, I have been thinking a lot about what it means to be a parent. Biological parenting (what I call “breeding”… why to be explained) is a Read More

New report on drug resistance highlights the tragedy of our antibiotics commons

Posted 02 Oct 2015 / 0

National Geographic Germination blog “Antibiotic Resistance Getting Worse Globally, But Fixes Could Be Simple” Antibiotic resistance is an interesting problem because it highlights how individual decisions drive international-scale dynamics and then come right back to impact individuals. Unlike other big international tragedies of the commons such as climate change or fisheries collapse, the effects of Read More

Open Tree of Life allows experts and novices alike to explore “the” phylogeny

Posted 29 Sep 2015 / 0

Proceedings of the National Academy of Sciences “Synthesis of phylogeny and taxonomy into a comprehensive tree of life” Open Tree of Life tree browser Although I am far from being an expert in or huge enthusiast of taxonomy and phylogeny, this is a project worth exploring. By synthesizing thousands of published phylogenies, this project presents Read More
