Contributions of woody and herbaceous vegetation to tropical savanna ecosystem productivity: a quasi-global estimate.
To estimate the relative contributions of woody and herbaceous vegetation to savanna productivity, we measured the 13C/12C isotopic ratios of leaves from trees, shrubs, grasses and the surface soil carbon pool for 22 savannas in Australia, Brazil and Ghana covering the full savanna spectrum ranging from almost pure grassland to closed woodlands on all three continents. All trees and shrubs samp...
متن کاملVegetation, fire, and feedbacks: a disturbance-mediated model of savannas.
Savanna models that are based on recurrent disturbances such as fire result in nonequilibrium savannas, but these models rarely incorporate vegetation feedbacks on fire frequency or include more than two states (grasses and trees). We develop a disturbance model that includes vegetation-fire feedbacks, using a system of differential equations to represent three main components of savannas: gras...
متن کاملGrass effects on tree (Prosopis glandulosa) growth in a temperate savanna
The majority of studies on woody–herbaceous interactions have focused on the effects of trees on grasses; relatively few have looked at grass effects on adult trees. In a two-year study in a temperate savanna in northern Texas, tree (Prosopis glandulosa) basal area increased significantly following removal of associated grasses, the response being highly variable in time and space. Tree respons...
متن کاملDisentangling How Landscape Spatial and Temporal Heterogeneity Affects Savanna Birds
In highly seasonal tropical environments, temporal changes in habitat and resources are a significant determinant of the spatial distribution of species. This study disentangles the effects of spatial and mid to long-term temporal heterogeneity in habitat on the diversity and abundance of savanna birds by testing four competing conceptual models of varying complexity. Focussing on sites in nort...
متن کاملCOMMUNITY ECOLOGY - METHODS PAPER Grasses and browsers reinforce landscape heterogeneity by excluding trees from ecosystem hotspots
Spatial heterogeneity in woody cover affects biodiversity and ecosystem function, and may be particularly influential in savanna ecosystems. Browsing and interactions with herbaceous plants can create and maintain heterogeneity in woody cover, but the relative importance of these drivers remains unclear, especially when considered across multiple edaphic contexts. In African savannas, abandoned...
