Despite the importance of fire and herbivory in structuring savanna systems, few replicated experiments have examined the interactive effects of herbivory and fire on plant dynamics. In addition, the effects of fire on associated ant-tree mutualisms have been largely unexplored. We carried out small controlled burns in each of 18 herbivore treatment plots of the Kenya Long-term Exclosure Experi...

Isolates from 12 legumes at three sites in Victoria showed a wide range of morphological, cultural, symbiotic, and serological properties. Isolates from Acacia longifolia var. sophorae and Kennedia prostrata were fast growing but nodulated ineffectively Macroptilium atropurpureum and all native legumes except Swainsonia lessertiifolia. Isolates from S. lessertiifolia showed anomalous properties...

This study evaluates the size frequency distribution of 11 trees and shrubs in the cloud forest in Wadi Garziz, southern Oman, in order to assess their current situation, which is affected by cutting, overgrazing and other constraints. A size class distribution and a vegetation structure analysis were applied in order to analyze the dynamics of this forest using census data from 51 plots select...

Three slow-growing rhizobial strains, designated RITF806(T), RITF807 and RITF211, isolated from root nodules of Acacia melanoxylon grown in Ganzhou city, Jiangxi Province, China, had been previously defined, based on amplified 16S rRNA gene restriction analysis, as a novel group within the genus Bradyrhizobium. To clarify their taxonomic position, these strains were further analysed and compare...

method has been developed in this laboratory using a gum acacia solution of proper specific gravity, hydrogen ion concentration, and osmotic pressure. Supravital studies of leukocytes separated by this method indicate that cells are viable and apparently undamaged . Preparation of solution: To io ml. ofdistilled water in a 100 ml. graduate (which has a stopper), 30 grams of gum acacia, and 30 m...
