Data from: Herbivore size matters for productivity-richness relationships in African savannas

Deron E. Burkepile, Richard W. S. Fynn, Dave I. Thompson, Nathan P. Lemoine, Sally E. Koerner, Stephanie Eby, Nicole Hagenah, Kevin R. Wilcox, Scott L. Collins, Kevin P. Kirkman, Alan K. Knapp & Melinda D. Smith
1.Productivity and herbivory often interact to shape plant community composition and species richness with levels of production mediating the impact of herbivory. Yet, differences in herbivore traits such as size, feeding guild, and dietary requirements may result in different impacts of diverse herbivore guilds across productivity gradients. 2.We used size-selective herbivore exclosures to separate the effects of herbivory by larger herbivores, such as elephant, Burchell's zebra, and blue wildebeest from those of medium/smaller herbivores, such...

Data from: Fire frequency drives habitat selection by a diverse herbivore guild impacting top–down control of plant communities in an African savanna

Deron E. Burkepile, Dave I. Thompson, Richard W. S. Fynn, Sally E. Koerner, Stephanie Eby, Navashni Govender, Nicole Hagenah, Nathan P. Lemoine, Katherine J. Matchett, Kevin R. Wilcox, Scott L. Collins, Kevin P. Kirkman, Alan K. Knapp & Melinda D. Smith
In areas with diverse herbivore communities such as African savannas, the frequency of disturbance by fire may alter the top–down role of different herbivore species on plant community dynamics. In a seven year experiment in the Kruger National Park, South Africa, we examined the habitat use of nine common herbivore species across annually burned, triennially burned and unburned areas. We also used two types of exclosures (plus open access controls) to examine the impacts of...

Data from: Rival group scent induces changes in dwarf mongoose immediate behaviour and subsequent movement

Charlotte Christensen, Julie M. Kern, Emily Bennitt & Andrew N. Radford
In many social species, groups of animals defend a shared territory against rival conspecifics. Intruders can be detected from a variety of cues, including fecal deposits, and the strength of response is expected to vary depending on the identity of the rival group. Previous studies examining differences in response to neighbor and stranger groups have focused on the immediate response to the relevant cues. Here, we investigated how simulated intrusions of rival groups affect both...

Data from: Effects of divergent migratory strategies on access to resources for Cape buffalo (Syncerus caffer caffer)

Emily Bennitt, Mpaphi Casper Bonyongo & Stephen Harris
Populations of large herbivores frequently display divergent migratory strategies, a likely consequence of the trade-off between the costs and benefits of migration. Globally, physical and environmental barriers disrupt migrations, leading to increased residency, which can have detrimental consequences. In the Okavango Delta, Botswana, veterinary cordon fences erected in 1982 may have caused enforced residency in some subpopulations of Cape buffalo (Syncerus caffer caffer). We used data from GPS-enabled collars fitted to females in 1 resident...
