Ecologists have long sought to understand the factors controlling the structure of savanna
vegetation. Using data from 2154 sites in savannas across Africa, Australia, and South America…

Objectives This report reviews the evidence on the hypothesis that education has important
social impacts on health. In reviewing the evidence, we highlight those studies that have …

Large herbivores play unique ecological roles and are disproportionately imperiled by
human activity. As many wild populations dwindle towards extinction, and as interest grows in …

The use of structural equation modeling (SEM) is often motivated by its utility for investigating
complex networks of relationships, but also because of its promise as a means of …

Human alterations to nutrient cycles 1 , 2 and herbivore communities 3 , 4 , 5 , 6 , 7 are affecting
global biodiversity dramatically 2 . Ecological theory predicts these changes should be …

How ecosystem productivity and species richness are interrelated is one of the most debated
subjects in the history of ecology 1 . Decades of intensive study have yet to discern the …

For more than 30 years, the relationship between net primary productivity and species richness
has generated intense debate in ecology about the processes regulating local diversity. …

For over 50 years, amphotericin has remained the powerful but highly toxic last line of
defense in treating life-threatening fungal infections in humans with minimal development of …

Morphological diversity within closely related species is an essential aspect of evolution and
adaptation. Mutations in the Melanocortin 1 receptor (Mc1r) gene contribute to pigmentary …

An experimental study of boiling heat transfer from a simulated microelectronic component
immersed in a stagnant pool of the dielectric Fluorinert (FC-72) is presented. Various …
