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

Urban Wildlife Podcast on Cats and Coyotes

Posted 20 Sep 2015 / 0

Urban Wildlife Podacast “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

The Urban Wildlife Podcast on big animals in big cities

Posted 27 Jul 2015 / 0

The 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

Zoonosis, Ebola, and the Elusive Reservoir Host

Posted 24 Jun 2015 / 0

There’s a really interesting article in the upcoming (July 2015) issue of National Geographic entitled “Stalking a Killer“. Using the most recent outbreak of Ebola in West Africa as a case study, the article looks at the nature of a variety of unusual and rare diseases caused by filoviruses. Ebola is not a virus that Read More

Our paper on a super-rational solution to the tragedy of the commons published in Scientific Reports

Posted 14 Jan 2015 / 0

I am very pleased to announce that a paper that I worked on with collaborators Jun-Zhou He, Rui-Wu Wang, and Yao-Tang Li has been published in the open-access journal Scientific Reports. The paper, entitled “Asymmetric interaction paired with a super-rational strategy might resolve the tragedy of the commons without requiring recognition or negotiation“, considers how Read More

Evolution 2014: Day 1

Posted 21 Jun 2014 / 0

My first session of the day was spent entirely in a Symbiosis session. I am fascinated by symbiosis, particularly mutualistic symbiosis, so I am always looking for cool new stories to help illustrate the concept for my students. This session featured a lot of talks on microbial symbionts, which are also of interest to me. The Read More

Evolution 2014: Could the right symbionts provide protection from chytrid infection to amphibians?

Posted 21 Jun 2014 / 0

Patrick McLaughlin showed work on Bioko Island suggesting that frogs there may be protected from the ill effects of chytrid infection by the presence of bacterial symbionts. These symbionts produce metabolites that lower rates of parasitic infection, suggesting that symbionts might be used to protect amphibian populations worldwide. It also suggests a mechanism by which Read More

Evolution 2014: Are island mutualist communities more likely to be nested because they are inherently more unstable?

Posted 21 Jun 2014 / 0

The interactions in ecological communities can be structured in a variety of ways, and recently there has been a push to categorize these networks along the spectrum between modular (smaller clusters of more specialized interactions) and nested (unclustered networks with more generalist species). Theoretically it is understood that the nested communities are more stable, so Read More
