The complexity of tropical forest structure defies simple characterization

April 10, 2006

In the last decade, the new theory of metabolic ecology has derived general predictions for a wide range of ecological patterns from fundamental physical and biochemical principles. Predictions for tree growth, mortality and size distributions are particularly significant in light of their potential to help explain globally important carbon stores and fluxes of tropical forests. In a forthcoming pair of papers in Ecology Letters, Muller-Landau and collaborators associated with the Center for Tropical Science test these predictions using large datasets from tropical forests around the world. Observed patterns of tree growth, mortality and abundance deviate substantially from the predictions of metabolic ecology theory, especially for large trees. Variation within and among forests is more consistent with alternative models presented by Muller-Landau and colleagues, models that can incorporate some of the complex variation in tree shapes, growing conditions, and mortality threats within and among diverse tropical forests.

The Consolations of Mortality: Making Sense of Death
by Andrew Stark (Author)

A penetrating and provocative exploration of human mortality, from Epicurus to Joan Didion

For those who don’t believe in an afterlife, the wisdom of the ages offers four great consolations for mortality: that death is benign and good; that mortal life provides its own kind of immortality; that true immortality would be awful; and that we experience the kinds of losses in life that we will eventually face in death. Can any of these consolations honestly reconcile us to our inevitable demise?

Old Mortality (Oxford World's Classics)
by Walter Scott (Author), Jane Stevenson (Author), Peter Davidson (Author)

Old Mortality (1816), which many consider the finest of Scott's Waverley novels, is a swift-moving historical romance that places an anachronistically liberal hero against the forces of fanaticism in seventeenth-century Scotland, in the period infamous as the `killing time'. Its central character, Henry Morton, joins the rebels in order to fight Scotland's royalist oppressors, little as he shares the Covenanters' extreme religious beliefs. He is torn between his love for a royalist's granddaughter and his loyalty to his downtrodden countrymen.

As well as being a tale... View Details
