Rainfall, land use and woody vegetation cover change in semi-arid Australian savanna
1 The relative roles of climate and management for driving changes in woody cover in savannas over the past century are the subject of active debate. Perspectives arising from short-term, small-scale, local experiments are rarely tested over larger scales and longer time frames. 2 Regression analysis and aerial photography were used to assess the relative importance of land-use history (fire an...
متن کاملEffects of repeated burning on woody vegetation structure and composition in a semi-arid southern African savanna
The objective of this study was to investigate the effects of repeated dry season annual hot fires on woody plants in a semi-arid southern African savanna in Zimbabwe. Parts of the National University of Science and Technology (NUST) research fields in Bulawayo, Zimbabwe have been burnt annually in the dry season between 1994 and 2003 in order to control bush encroachment. The present study was...

متن کاملRoadside flora in arid and semi-arid natural areas (Case study: Northern Khorasan province, Iran)
Roads have an important role in plants dispersal on different scales. Various plant species settle on roadsides, but some of them can enter the natural environments and threaten their biodiversity. Worldwide knowledge of roadside flora is necessary for local and global management of natural areas. Accordingly, the roadside flora of Northern Khorasan rangelands was studied along the 600 km ...
متن کاملSeasonal Diet and Prey Preference of the African Lion in a Waterhole-Driven Semi-Arid Savanna
Large carnivores inhabiting ecosystems with heterogeneously distributed environmental resources with strong seasonal variations frequently employ opportunistic foraging strategies, often typified by seasonal switches in diet. In semi-arid ecosystems, herbivore distribution is generally more homogeneous in the wet season, when surface water is abundant, than in the dry season when only permanent...
