Biodiversity today has the unusual property that 85% of plant and animal species live on
land rather than in the sea, and half of these live in tropical rainforests. An explosive boost to …

To a first approximation, the distribution of biodiversity across the Earth can be described in
terms of a relatively small number of broad-scale spatial patterns. Although these patterns …

This book explores the geography, ecology, and antiquity of'open ecosystems', which
include grasslands, savannas, and shrublands. They occur in climates that can support …

Known for centuries, the geographical pattern of increasing biodiversity from the poles to the
equator is one of the most pervasive features of life on Earth. A longstanding goal of …

The decline of biodiversity with latitude has received great attention, but both the concise
pattern and the causes of the gradient are under strong debate. Most studies of the …

▪ Abstract The latitudinal gradient of decreasing richness from tropical to extratropical areas
is ecology's longest recognized pattern. Nonetheless, notable exceptions to the general …

An Introduction to Organic Geochemistry explores the fate of organic matter of all types,
biogenic and man-made, in the Earth System. investigates the variety of pathways and …

A latitudinal gradient in biodiversity has existed since before the time of the dinosaurs, yet
how and why this gradient arose remains unresolved. Here we review two major hypotheses …

Aim Current weaknesses of diversity theory include: a failure to distinguish different
biogeographical response variables under the general heading of diversity; and a general …

The present study proposes to reconcile the different spatial and temporal scales of regional
species production and local constraint on species richness. Although interactions between …
