ODD POLLINATORS

Insects and plants are intimately linked in terms of their ecology and evolution. Insects and vascular plants both first appear in the fossil record around 400 MY ago, at the beginning of the Devonian, as terrestrial ecology changed to allow the colonization of the land.
Then about 20 MY later, the first arboreal plants appear, and [...]

SAVE THE PARROTFISH TO SAVE THE REEFS

November 2007
Parrotfish are major grazers of the algae that grow on coral reefs. Protecting them from over-fishing may be decisive for the survival of reefs in the Caribbean. Sea urchins can also do the trick. That’s the take-home message of a Nature article, most of which consists are rather hard to follow mathematical modelling – ecology is not all (or [...]

ARE WHALES LIKE LYNX?

May 2007
Part of the complexity of understanding population cycles is that species can end up too successful, become so numerous that they eat all their food sources, then have a catastrophic collapse, before slowly rebuilding their population size. This is often seen with predators like lynx. Is this what is happening to the Pacific whale? How could we test [...]

EXTINCTION AND SPECIATION

March 2007
Interesting article in Science looking at the role of latitude in extinction and speciation. The authors conclude: ” most efforts have aimed at identifying the geological, climatic, and ecological factors that might have elevated tropical speciation rates, our results suggest that both speciation and extinction vary with latitude and contributed importantly to the latitudinal diversity gradient.” You or your [...]
