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

    Fynn, Richard, W.S.; Burkepile, Deron E.; Thompson, Dave, I.; Koerner, Sally E.; Eby, Stephanie; Govender, Navashni; Hagenah, Nicole; Lemoine, Nathan P.; Matchett, Catherine J.; Wilcox, Kevin R.; Collins, Scott L.; Kirkman, Kevin P.; Knapp, Alan K.; Smith, Melinda D. (Nordic Society Oikos, www.nordicsocietyoikos.org/, 2016)
    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 ...

  • Herbivore size matters for productivity-richness relationships in African savannas 

    Fynn, Richard, W.S.; Burkepile, Deron E.; Thompson, Dave I.; Lemoine, Nathan P.; Koerner, Sally E.; Eby, Stephanie; Hagenah, Nicole; Wilcox, Kevin R.; Collins, Scott L.; Kirkman, Kevin P.; Knapp, Alan K.; Smith, Melinda D. (British Ecological Society, https://www.britishecologicalsociety.org/, 2017-05)
    Productivity and herbivory often interact to shape plant community composition and species richness with levels of production mediating the impact of herbivory. However, differences in herbivore traits such as size, feeding ...
