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.

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

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

A niche with the masses?

Posted 22 Jun 2015 / 0

The Chronicle of Higher Education “You Want to Write for a Popular Audience? Really?” Sometimes I feel bummed out that I do not occupy a seat in a ‘normal’ academic department. But when I read about or encounter the attitudes that pervade these ‘normal’ places, I am really happy to have the freedom associated with Read More

Can we resolve the ‘group selection debate’ by focusing on human cooperation?

Posted 12 Jun 2015 / 13

ASEBL Journal “Morality and Selection – How?” This is an interesting article that tries to frame the debate over multilevel selection. Lots of other people have tried to similarly frame this debate, and I am pretty sure that no single prescription is going to resolve the debate. There is a debate about whether we need Read More

In the end, climate compromise comes down to writing and editing

Posted 01 Jun 2015 / 0

National Public Radio Morning Edition “Editing The Climate Talkers: Punctuation’s Effect On Earth’s Fate” I would suggest that the future of human civilization depends on reaching an international agreement to put a halt to — and partially reverse — anthropogenic climate change. Although the history of climate change agreements is pretty fraught, it does appear Read More

New article in Science provides a comprehensive overview and update on Yellowstone National Park

Posted 24 Apr 2015 / 0

Since I began teaching Ecology at Pratt, I have used the re-introduction of wolves to Yellowstone as the cornerstone case study of my community ecology lessons. Using material originally developed by my colleague Damon Chaky for the Ecology for Architects course, I ask my students to use ecological theory to explain some of the changes that Read More

PCB Bioaccumulation and Polar Bear Penises

Posted 20 Feb 2015 / 0

National Geographic News “Is Pollution Weakening Polar Bears’ Ability to Mate?” This sounds like fodder for a late-night television laugh line, but this is a pretty scary example of how bioaccumulation of toxins can have important conservation consequences. From a conservation perspective, there is nothing worse than a ubiquitous pollutant reducing the ability of a Read More
