In bird reproduction, parasitism and cooperation coevolve

Posted 21 Jan 2014 / 0

Science “How Cooperation Defeats Cheats” Science “Brood Parasitism and the Evolution of Cooperative Breeding in Birds” Live Science “How Birds Cooperate to Defeat Cuckoos” It is fascinating that being a cooperative breeder is both attractive to parasites (because they can achieve better reproductive success by successfully parasitizing the nest of cooperative breeders) and the best way to Read More

Scientific American “Tiny Plants” article provides a primer on the inter-relationship between ecological and evolutionary change

Posted 07 Jan 2014 / 0

I am always on the lookout for great popular science articles to assign to my students. What makes a popular science article great? Well, to start with it should address concepts that are core to my classes (admittedly, this definition of “greatness” is highly relative to what I decide is important to teach). Concept density Read More

Caterpillars weaponize nicotine

Posted 02 Jan 2014 / 0

The Economist “Caterpillars that blow nicotine at their enemy” I love the combination of genetic manipulation and “arena of death” wolf-spider gauntlet that led to these findings.

A tour of your diverse microbiome, and the things that might deplete that diversity

Posted 09 Sep 2013 / 0

NPR Morning Edition “From Birth, Our Microbes Become As Personal As A Fingerprint” It’s a bit corny, but this is a great tour of our diverse microbiome. It is critical that people start to recognize how potentially-damaging overuse of antibiotics and fear of bacteria could be to our health. It will be exciting to see Read More

Zero determinant strategy is just another short-term adaptation

Posted 15 Aug 2013 / 0

The Scientist “A Twist in Evolutionary Game Theory: Biologists demonstrate the instability of employing a selfish strategy in the prisoner’s dilemma game” Nature Communications “Evolutionary instability of zero-determinant strategies demonstrates that winning is not everything” I am so glad to see that someone did the math and simulations to look at the long-term stability of Read More

Dog license dataset opens up huge potential for understanding the dog-human mutualism

Posted 26 Jan 2013 / 0

WNYC “NYC’s Top Dogs: Mapping Names & Breeds in the City” WNYC “Dogs of NYC” Data sets like these, even flawed by their incompleteness (only 20% of dogs in New York City are registered) are fascinating. The human relationship with dogs has changed radically as we have urbanized as a species: I would suggest that the dominance Read More

National Geographic feature on penguin propulsion

Posted 22 Nov 2012 / 0

This month’s National Geographic features a valuable article called “Escape Velocity” that chronicles how Emperor Penguins reach incredible velocities to launch through holes in the ice and out into safety. Mostly a pictorial featuring Paul Nicklen’s amazing underwater photography, the article shows how these penguins use the controlled release of air trapped in their feathers to reach Read More
