Landscape-scale variation in plant community composition of an African savanna from airborne species mapping

Information on landscape-scale patterns in species distributions and community types is vital for ecological science and effective conservation assessment and planning. However, detailed maps of plant community structure at landscape scales seldom …

The rate and spatial pattern of treefall in a savanna landscape

Loss of large trees in savanna parks is of biodiversity conservation concern as trees contribute substantially to system biomass, heterogeneity and ecological functioning. Using airborne light detection and ranging (LiDAR), we monitored 119,775 …

Landscape-scale effects of herbivores on treefall in African savannas

Herbivores cause treefalls in African savannas, but rates are unknown at large scales required to forecast changes in biodiversity and ecosystem processes. We combined landscape-scale herbivore exclosures with repeat airborne Light Detection and …

Spatial patterns in the effects of fire on savanna vegetation three-dimensional structure

Understanding the causes and consequences of animal movements is of fundamental biological interest because any alteration in movement can have direct and indirect effects on ecosystem structure and function. It is also crucial for assisting spatial …

Context-dependent vegetation dynamics in an African savanna

Large-scale impacts of herbivores on the structural diversity of African savannas

African savannas are undergoing management intensification, and decision makers are increasingly challenged to balance the needs of large herbivore populations with the maintenance of vegetation and ecosystem diversity. Ensuring the sustainability of …
