Gas exchange and carbon allocation patterns were studied in two populations of Panicum coloratum, an Africa C-4 grass. The plants were grown in split-root pots, containing partially sterilized soil, with one side either inoculated (I) or not inoculat

The deciduous N-fixing shrub Myrica gale L. and the evergreen sclerophyllous shrub Chamaedaphne calyculata (L.) Moench sometimes intermingle in small patches in boreal peatlands. The mineral element composition of adjacent plants and plant parts may

Resident grazing ungulates in the Serengeti National Park, Tanzania, are conspicuously patchy in their distribution among regions of the Park. Linear programming models that maximize nitrogen (N) consumption by foraging ungulates in Serengeti regions

Savanna-grassland ecosystems are highly interactive due to effects among interconnected trophic elements. This can cause disturbance at one level in the trophic web to be propagated through that web to have effects far removed from the initial locus

A factorial experiment was performed to evaluate the relationships between defoliation and canopy closure, recognizing that a major effect of grazing in nature is to prevent that closure. Short (Eustachys paspaloides) and mid—height (Themeda triand

Population samples of an African C4 grass, Panicum coloratum L., were collected from two locations in the Serengeti Grasslands varying in grazing intensity, one a high—grazing location (GA = grazing—adapted), the other a low—grazing location (N

The concentration of soil sodium (Na) is an important factor that influences species distribution in the Serengeti short-grass plains, Tanzania. Experiments were conducted to characterize physiological (growth, photosynthetic, nutrients, and water re

The evidence that pure ecological science has influenced grazing management practices employed in livestock husbandry on the North American Great Plains is tenuous at best. Those practices arose from critical technological innovations in the 19th cen

In the Serengeti National Park, Tanzania, precipitation and soil nitrogen vary greatly between northwestern tallgrass areas and southeastern shortgrass areas, with the tallgrass having higher total precipitation and lower soil fertility. We used a mo
