Did you see a plant there? Me neither.

At a seminar on sexual selection in frogs I attended recently, an evolutionary ecologist (who studies plants), joked that compared to things like frogs that make noise and move, plants are really pretty dull. I can think of many reasons why plants are in fact the awesomest (being in the plant biology department makes me a little biased), and one particular example that came to mind was from an Am … Continue reading

A trip along the diversity effects highway: a new and exciting fork in the road

The dynamic dune ecosystem along Lake Michigan was where I first came to appreciate nature as a young child (granted, I was in the water most of the time). Blissfully unaware of the pioneering work of Cowles (1899), it was my time wandering forward and backward through successional time as I matured into a young man that put me on the road to studying ecology. So, when I came across … Continue reading

No return of diversity?

In the past few decades, there has been an increasing concern and therefore research into the eutrophication of natural ecosystems caused by high levels of nitrogen addition. Some studies, such as Foster and Gross 1998 and Clark and Tilman 2008 (among others), have shown that nitrogen fertilization leads to a decrease in the diversity of communities. However, the long-term consequences of these actions are not well understood. How quickly do the nitrogen … Continue reading

All I Really Need to Know, I Learned from Aphids

In our lab, we throw around the terms “eco-evolutionary dynamics” or “eco-evolutionary feedbacks” pretty loosely to describe any interactions between ecological and evolutionary processes (two more terms that are defined pretty abstractly). But we can do a better job of defining eco-evolutionary feedbacks, and a recent paper by Martin Turcotte, Dave Reznick, and Daniel Hare reminded me of that. This is another paper from the Eco-Evo special feature in The … Continue reading

Parasitism Threatens Mutualism

Background: The world is a complicated place. Organisms typically interact with one another simultaneously and the strength of interactions can depend on what’s happening in the environment. As a number of organisms within a community increases, indirect interactions also increase exponentially (Abrahams 1992). As ecologists, we’re fascinated by the beauty of this complex world while we struggle to understand and predict how nature really works. Studying a pair-wise interaction is … Continue reading
