Understanding the cascading effect of carnivore loss… before we lose all the carnivores

Posted 25 Jan 2014 / 0

NPR Morning Edition “When Big Carnivores Go Down, Even Vegetarians Take The Hit” Science “Status and Ecological Effects of the World’s Largest Carnivores” Both of these articles are great for introducing the idea of trophic cascades as well as how trophic inefficiency implies that large predators require large ranges containing abundant prey.

Once considered clear, the line between ecological and evolutionary time scales is becoming more blurry

The Chronicle of Higher Education “What Darwin Got Wrong” Great article on the importance of better understanding rapid and/or fluctuating evolution! The number of applications to applied human issues is fascinating.

With all we know, we still know too little to reliably re-engineer ecosystems

Posted 06 Sep 2013 / 0

NPR Morning Edition “Saving One Species At The Expense Of Another” There are a number of really important points made by this nice short. The first is that scientists — even when acting carefully on the best available evidence and theory — can still fail to produce desired outcomes. The second is that modifying ecological communities Read More

Aquatic food chains have gotten longer and less diverse over evolutionary time

PLos One “Shorter Food Chain Length in Ancient Lakes: Evidence from a Global Synthesis” What I wonder is: what is the mechanism by which these communities evolve away from their initial “short-and-wide” configuration?

Big felines have lots of commensal fans

Posted 19 Jun 2012 / 0

Science Now “Pumas Leave Table Scraps” This is an interesting story because it suggests that Pumas maintain strong ecological interaction strengths with not just their prey but also all these commensal species. This finding makes it a lot harder to discount top predators as simply consumers whose only role is in depleting prey populations: for Read More
