Large herbivores affect the stoichiometry of nutrients in a regenerating woodland ecosystem
Article Abstract:
An examination on the influence of browsing by red deer on the relative availability of nitrogen (N) and phosphorus (P) in a regenerating woodland ecosystem is presented. Results reveal that removal of browsing by fencing for 14 years led to a shift from N toward P limitation of the dominant tree species Betula pubescens, thus indicating that herbivores have the potential to significantly affect the stoichiometry of N and P in forest ecosystem.

Defensive traits of savanna trees-the role of shoot exposure to browsers
Article Abstract:
A study was conducted on 13 tree species in Botswana to investigate the patterns of plant defense. The results indicate that general theories of plant defense, originating from boreal and northern temperate forests, cannot be simply applied to savanna ecosystems.
