Mahesh Sankaran,Niall P. Hanan,Robert J. Scholes,Jayashree Ratnam,David J. Augustine,Brian S. Cade,Jacques Gignoux,Steven I. Higgins,Xavier Le Roux,Fulco Ludwig,Jonas Ardö,Feetham Banyikwa,Andries Bronn,Gabriela Bucini,Kelly K. Caylor,Michael B. Coughenour,Alioune Diouf,Wellington N. Ekaya,Christie J. Feral,Edmund C. February,Peter G. H. Frost,Pierre Hiernaux,Halszka Hrabar,Kristine L. Metzger,Herbert H. T. Prins,Susan Ringrose,William B. Sea,Jörg Tews,Jeff Worden,Nick Zambatis +29 more
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.
Journal ArticleDOI
A Disease-Mediated Trophic Cascade in the Serengeti and its Implications for Ecosystem C
Ricardo M. Holdo,Anthony R. E. Sinclair,Andrew P. Dobson,Kristine L. Metzger,Benjamin M. Bolker,Mark E. Ritchie,Robert D. Holt +6 more
TL;DR: The removal of rinderpest had cascading effects on herbivore populations, fire, tree density, and even ecosystem carbon in the Serengeti ecosystem of East Africa.
Journal ArticleDOI
Inorganic nitrogen availability after severe stand-replacing fire in the Greater Yellowstone ecosystem
Monica G. Turner,Erica A. H. Smithwick,Kristine L. Metzger,Daniel B. Tinker,William H. Romme +4 more
TL;DR: Postfire forests in Yellowstone seem to be highly conservative for nitrogen, and microbial immobilization of ammonium plays a key role during early succession, confirming earlier hypotheses about postdisturbance succession and nutrient cycling in cold, fire-dominated coniferous forests.
Journal ArticleDOI
The spatial distribution of vegetation types in the Serengeti ecosystem: the influence of rainfall and topographic relief on vegetation patch characteristics
TL;DR: In this paper, a structural vegetation map of the Serengeti ecosystem is presented along with a detailed summary of the distribution of land-cover classes and spatial heterogeneity in the ecosystem.
Journal ArticleDOI
Predictability of anthrax infection in the Serengeti, Tanzania.
Katie Hampson,Tiziana Lembo,Paul R. Bessell,Harriet Auty,Craig Packer,Jo E. B. Halliday,Cari A. Beesley,Robert D. Fyumagwa,Richard Hoare,Eblate Ernest,Christine Mentzel,Kristine L. Metzger,Titus Mlengeya,Karen Stamey,Keith Roberts,Patricia P. Wilkins,Sarah Cleaveland +16 more
TL;DR: It is suggested that soil alkalinity and prolonged droughts or rains are useful predictors of disease occurrence that could guide risk-based surveillance and shed light on ecological drivers of anthrax infection.
