Cahill, J.F., Ingersoll, C.M., Niesenbaum, R.A.
Simply visiting and manipulating plants in a way consistent with measurement in typical ecological studies influences the amount of leaf herbivory experienced by some plant species. We examined the mechanistic basis for why Apocynum cannabinum is particularly responsive to such visitation and...

We investigated whether plant interaction intensity in a subarctic-alpine meadow is important for determining community structure and species abundance. Using two common species as phytometers, we measured interaction intensity using a neighbor removal approach. Eight biotic and abiotic variables...

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...
