TL;DR: It is shown that ecological effects of habitat heterogeneity may vary considerably between species groups depending on whether structural attributes are perceived as heterogeneity or fragmentation, and possible effects may also vary relative to the structural variable measured.

TL;DR: It is shown, using data from 854 sites across Africa, that maximum woody cover in savannas receiving a mean annual precipitation (MAP) of less than ∼650 mm is constrained by, and increases linearly with, MAP.

TL;DR: This characterize this mosaic for a Central Amazon forest by integrating field plot data, remote sensing disturbance probability distribution functions, and individual-based simulation modeling demonstrates that a steady state of patches of varying successional age occurs over a relatively large spatial scale, with important implications for detecting temporal trends on plots that sample a small fraction of the landscape.

TL;DR: In this article, the authors reviewed 85 publications for the period 1960-2003 and showed that ecological effects of habitat heterogeneity may vary considerably between species groups depending on whether structural attributes are perceived as heterogeneity or fragmentation.

TL;DR: In this paper, the impact of climate change, cattle grazing, and wood cutting on shrub cover dynamics in semiarid savannas of the southern Kalahari was studied.
