Simard, S. W., Cahill Jr, J. F., Erbilgin, N., RolTreu, J., Karst, M., Pec, J., Cigan, P. W., Cooke, J. E. K., Gregory, R.
Forest die-off caused by mountain pine beetle (MPB; Dendroctonus ponderosa) is rapidly transforming western North American landscapes. The rapid and widespread death of lodgepole pine (Pinus contorta) will likely have cascading effects on biodiversity. One group particularly prone to such...

Direct and indirect drivers of plant diversity responses to climate and clipping across northern temperate grassland
Download2014
Bork, E. W., White, S. R., Cahill Jr, J. F.
It is well known that climate can influence plant community assembly via a multitude of indirect and direct pathways. However, interpretations of plant diversity responses to simulated climate change experiments, and subsequent predictions of plant communities under future climate scenarios,...

McNickle, G. G., Deyholos, M. K., Cahill Jr, J. F.
Background Ecologists recognize that plants capture nitrogen in many chemical forms that include amino acids. Access to multiple nitrogen types in plant communities has been argued to enhance plant performance, access to nitrogen and alter ecological interactions in ways that may promote...

Plant Phenotypic Plasticity Belowground: A Phylogenetic Perspective on Root Foraging Trade‐Offs
Download2005
Cahill Jr, J. F., Kembel, S. W.
Many plants proliferate roots in nutrient patches, presumably increasing nutrient uptake and plant fitness. Nutrient heterogeneity has been hypothesized to maintain community diversity because of a trade‐off between the spatial extent over which plants forage (foraging scale) and their ability to...

Boutin, S., He, F., Sólymos, P., Cahill Jr, J. F., Mayor, S.J.
The worldwide biodiversity crisis has intensified the need to better understand how biodiversity and human disturbance are related. The 'intermediate disturbance hypothesis' suggests that disturbance regimes generate predictable non-linear patterns in species richness. Evidence often contradicts...

Interactions among the foraging behaviours of co-occurring animal species can impact population and community dynamics; the consequences of interactions between plant and animal foraging behaviours have received less attention. In North American forests, invasions by European earthworms have led...

We examined whether the intense root competition in a rough fescue grassland plant community in central Alberta, Canada, was important in structuring plant species diversity or community composition. We measured competition intensity across gradients of species richness, evenness, and community...
