Seasonal variation in the relative dominance of herbivore guilds in an African savanna
(Ecological Society of America, 2016)
African savannas are highly seasonal with a diverse array of both mammalian and invertebrate herbivores, yet herbivory studies have focused almost exclusively on mammals. We conducted a 2-yr exclosure experiment in South ...
Spatial variability and abiotic derterminants of termite mounds throughout a savanna catchment.
(Nordic Society Oikos, 2014-03)
Termite mounds contribute to the spatial heterogeneity of ecological processes in many savannas, but the underlying patterns and determinants of mound distributions remain poorly understood. Using the Carnegie Airborne ...
Termite mounds differ in their importance for herbivores across savanna types, seasons and spatial scales
(Nordic Society Oikos, 2016)
Herbivores do not forage uniformly across landscapes, but select for patches of higher nutrition and lower predation risk. Macrotermes mounds contain higher concentrations of soil nutrients and support grasses of higher ...
Variable effects of termite mounds on African savanna grass communities across a rainfall gradient
(International Association for Vegetation Science, 2014-05)
Questions: Termite mounds of the genus Macrotermes are prominent features in African savannas, forming nutrient hotspots that support greater plant diversity, which is of higher nutritional value than the surrounding ...
Woody encroachment slows decomposition and termite activity in an African savannah
(John Wiley & Sons Ltd, 2018)
Woody encroachment can lead to a complete switch from open habitats to dense thickets, and has the potential to greatly alter the biodiversity and ecological functioning of grassy ecosystems across the globe. Plant litter ...
