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

An Ecological Approach to Invasion Resistance – Insights from the World of Fashion

Old fashions are often recycled by new generations of young people attempting to stand out and be unique (just like everyone else!). Bell bottomed jeans, the paragon of 1970s fashion, saw a (thankfully brief) resurgence in the late 1980s. More recently, the leg warmers and popped collars of the 1980s were suddenly cool again. Strangely enough, ideas in ecology often reappear on a similar 15-20 year cycle. In the case … Continue reading

Consider the Ocean

A recent paper in Ecological Applications put a classic theory to the test, with a twist. The theory of island biogeography was one of the first conceptual frameworks to provide guidance for the conservation of biodiversity on a landscape scale. It’s pretty intuitive stuff. Changes in species diversity on ecological time scales (i.e., over decades) in any habitat are the result of colonizing species minus species extinctions. MacArthur and Wilson … Continue reading

Communities Can Be Keystone Too

Since Paine’s classic work in the rocky intertidal describing the effects of Pisaster  starfish on the community as a keystone predator species, the concept has become huge to ecology. A keystone species is one with an important role in the community and has a larger effect on the community than would be expected by its abundance. In the rocky intertidal, when starfish were removed from the system, the population size … Continue reading
