Introduction to the Special Issue: Beyond traits: integrating behaviour into plant ecology and biology
Download2015-01-01
The way that plants are conceptualized in the context of ecological understanding is changing. In one direction, a reductionist school ispullingplants apart into alistof measured‘traits’, fromwhichecological functionand outcomesofspecies interactions may be inferred. This special issue offers an...

Large-scale insect outbreak homogenizes the spatial structure of ectomycorrhizal fungal communities
Download2019-01-01
Ectomycorrhizal fungi (plant symbionts) are diverse and exist within spatially variable communities that play fundamental roles in the functioning of terrestrial ecosystems. However, the underlying ecological mechanisms that maintain and regulate the spatial structuring of ectomycorrhizal fungal...

Light, wind, and touch influence leaf chemistry and rates of herbivory in Apocynum cannabinum (Apocynaceae)
Download2006-01-01
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...

Limited effects of soil nutrient heterogeneity on populations of Abutilon theophrasti (Malvaceae)
Download1996-01-01
An experiment was conducted to determine if spatial nutrient heterogeneity affects mean plant size or size hierarchies in experimental populations of the weedy annual Abutilon theophrasti Medic. (Malvaceae). Heterogeneity was imposed by alternating 8 X 8 X 10 cm blocks of low and high nutrient...

Limited impacts of extensive human land use on dominance, specialization, and biotic homogenization in boreal plant communities
Download2015-01-01
Mayor, S. J., Boutin, S., He, F., Cahill, J. F.
Background Niche theory predicts that human disturbance should influence the assembly of communities, favouring functionally homogeneous communities dominated by few but widespread generalists. The decline and loss of specialists leaves communities with species that are functionally more similar....

2015-01-01
Soil microbial communities and processes have repeatedly been shown to impact plant community assembly and population growth. Soil-driven effects may be particularly pronounced with the introduction of plants to non-native ranges, as introduced plants are not typically accompanied by transference...

Cahill, J. F., Mitchell, M. G. E., Hik, D. S.
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...

Plant phenotypic plasticity belowground: a phylogenetic perspective on root foraging trade-offs
Download2005-01-01
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...

McNickle, G. G., Cahill jr, J. F.
All organisms must find and consume resources to live, and the strategies an organism uses when foraging can have significant impacts on their fitness. Models assuming optimality in foraging behavior, and which quantitatively account for the costs, benefits, and biological constraints of...

Population-level Responses to Nutrient Heterogeneity and Density by Abutilon Theophrasti (Malvaceae): An Experimental Neigborhood Approach
Download1998-01-01
An experimental approach was used to examine the effects of spatial nutrient heterogeneity and planting density on the sizes of plants within populations of Abutilon theophrasti. Planting locations were generated using random numbers and replicated among populations growing on two different...
