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, ... -
Evidence of nutrient translocation in response to smoke exposure by the East African ant acacia, Vachellia drepanolobium
Kimuyu, Duncan M.; Martins, Dino J.; Pierce, Naomi E.; Yekwayo, Inam; Ye, Wenqing; Wu, Donghao; Perez-Martinez, Christian A.; Ziemke, Clayton H.; Kennedy-Yoon, Annina; Darling, Walker S.; Blumstein, Meghan; Dean, Brendan Z. M.; Angier, Katherine I. W.; Rabideau-Childers, Richard (Wiley & Sons Ltd, 2021-09)1. Fire is a major selective force on arid grassland communities, favoring traits such as the smoke-induced seed germination response seen in a wide variety of plant species. However, little is known about the relevance ... -
Fine‐scale variation in soil and topography influences herbaceous vegetation and the distribution of large mammalian herbivores
Ang'ila, Robert O.; Kimuyu, Duncan M.; Wambugu, Geoffrey M.; Kenfack, David; Musil, Paul M.; Kartzinel, Tyler R. (Wiley, 2023-04)Current understanding of the distribution of vegetation and large mammalian herbivores (LMH) is based on a combination of biogeographic studies and highly controlled field experiments, but a more complete understanding ... -
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 ... -
Seed dispersal by Tana River mangabeys in fragmented gallery forests
Kimuyu, Duncan M.; Wahungu, Geoffrey M.; Otieno, Dennis O. (SciRes, 2012) -
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 ... -

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) -
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 ...
