5. Absentee owners and overlapping home ranges in a territorial species
Isbell, Lynne A.; Bidner, Laura R.; Loftus, Carter; Kimuyu, Duncan M.; Young, Truman P. (2021-01-07)Abstract Understanding animals’ use of space can shed valuable light on multiple other aspects of behavioral ecology, including social organization, dispersal, and foraging efficiency. Home ranges, territories, core areas, ... -
Fire disturbance disrupts an acacia ant–plant mutualism in favor of a subordinate ant species
Kimuyu, Duncan K.; Sensenig, Ryan L.; Guajardo, Juan C. Ruiz; Veblen, Kari E.; Riginos, Corinna; Young, Truman P. (Wiley and sons, 2017-03)Although disturbance theory has been recognized as a useful framework in examining the stability of ant–plant mutualisms, very few studies have examined the effects of fire disturbance on these mutualisms. In myrmecophyt ... -
Influence of cattle on browsing and grazing wildlife varies with rainfall and presence of megaherbivores
Kimuyu, Duncan M.; Kari, E. Vebien; Corinna, Riginos; Chira, Robert M.; Githaiga, John M.; Young, Truman P. (The Ecological Society of America, 2017)In many savanna ecosystems worldwide, livestock share the landscape and its resources with wildlife. The nature of interactions between livestock and wildlife is a subject of considerable interest and speculation, yet ... -
Naïve plant communities and individuals may initially suffer in the face of reintroduced megafauna: An experimental exploration of rewilding from an African savanna rangeland
Young, Truman P.; Kimuyu, Duncan M.; Odadi, Wilfred O.; M.Wells, Harry B.; Wolf, Amelia A. (PLOS ONE, 2021-04-06)Excluding large native mammals is an inverse test of rewilding. A 25-year exclosure experiment in an African savanna rangeland offers insight into the potentials and pitfalls of the rewilding endeavor as they relate to the ... -
Relationships Between Cattle and Biodiversity in Multiuse Landscape Revealed by Kenya Long-Term Exclosure Experiment
Kimuyu, Duncan M.; Young, Truman P.; Porensky, Lauren M.; Riginos, Corinna; Veblen, Kari E.; Odadi, Wilfred O.; Charles, Grace K.; Young, Hillary S. (Elsevier, 2018-05)On rangelands worldwide, cattle interact with many forms of biodiversity, most obviously with vegetation and other large herbivores. Since 1995, we have been manipulating the presence of cattle, mesoherbivores, and ... -
Spatial scales influence long-term response of herbivores to prescribed burning in a savanna ecosystem
Kimuyu, Duncan M.; Sensenig, Ryan L.; Chira, Robert M.; Githaiga, John M.; Young, Truman P. (CSIRO PUBLISHING, 2017-04)Both wild and prescribed fire in savanna ecosystems influence habitat use by herbivores by creating or maintaining spatial and temporal heterogeneity in forage quality and vegetation cover. Yet little is known about how ... -
Spatial scales influence long-term response of herbivores to prescribed burning in a savanna ecosystem
Kimuyu, Duncan M.; Sensenig, Ryan L.; Chira, Robert M.; Githaiga, John M.; Young, Truman P. (CSIRO PUBLISHING, 2017-01)Both wild and prescribed fire in savanna ecosystems influence habitat use by herbivores by creating or maintaining spatial and temporal heterogeneity in forage quality and vegetation cover. Yet little is known about how ... -
Synergistic effects of fire and elephants on arboreal animals in an African savanna
Sensenig, Ryan L.; Pringle, Robert M.; Kimuyu, Duncan M.; Palmer, Todd M.; Corinna Riginos; Veblen, Kari E.; Young, Truman P. (British Ecological Society, 2015) -
Synergistic effects of long-term herbivory and previous fire on fine-scale heterogeneity of prescribed grassland burns
Kimuyu, Duncan; Werner, Chhaya M.; Veblen, Kari E.; Sensenig, Ryan L.; LaMalfa, Eric; Young, Truman P. (Ecology, 2020-10)Grassland and savanna ecosystems, important for both livelihoods and biodiversity conservation, are strongly affected by ecosystem drivers such as herbivory, fire, and drought. Interactions among fire, herbivores and ... -
Tree resprout dynamics following fire depend on herbivory by wild ungulate herbivores
Kimuyu, Duncan M.; LaMalfa, Eric M.; Sensenig, Ryan L.; Young, Truman P.; Riginos, Corinna; Veblen, Kari E. (Journal of Ecology, 2019-04)1. Savanna tree cover is dynamic due to disturbances such as fire and herbivory. Frequent fires can limit a key demographic transition from sapling to adult height classes in savanna trees. Saplings may be caught in a ‘fire ...
