Reexamining Sample Size Requirements for Multivariate, Abundance-Based Community Research: When Resources are Limited, the Research Does Not Have to Be
Download2015-01-01
Forcino, F. L., Leighton, L. R., Twerdy, P., Cahill, J. F.
Community ecologists commonly perform multivariate techniques (e.g., ordination, cluster analysis) to assess patterns and gradients of taxonomic variation. A critical requirement for a meaningful statistical analysis is accurate information on the taxa found within an ecological sample. However,...

Reid, T.A., Cahill, J.F., Navabi, A.
Competition with weeds decreases crop yields globally. Breeding for competitive ability against elevated weed pressure can be difficult because the selection for specific traits which contribute to competitive ability may result in yield losses. The widely studied International Triticeae Mapping...

Cameron, E. K., Cahill Jr, J. F., Bayne, E. M.
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...

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...

Alberta grassland plant trait data
2020-06-11
Plant trait data collected and processed by the Cahill Lab in Experimental Plant Ecology. The core data was collected with funding provided by the Rangeland Research Institute, University of Alberta. Included are raw data for core plant traits, including root and leaf characteristics. Standard...

Grazing by wild and domesticated grazers occurs within many terrestrial ecosystems worldwide, with positive and negative impacts on biodiversity. Management of grazed lands in support of biological conservation could benefit from a compiled dataset of animal biodiversity within and adjacent to...

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...

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...

Coordinated distributed experiments: An emerging tool for testing global hypotheses in ecology and environmental science
Download2013-01-01
Knapp, A. K., Collins, S. L., Turkington, R. , Long, R., White, S., Cahill, J. F., Carlyle, C. N., Beierkuhnlein, C., Luo, Y., Casper, B. B. Cleland, E., Lind, E., Smith, M. D., Henry, H. A. L., Dukes, J. S., Fraser, L. H., Reich, P. B., Sternberg, M.
There is a growing realization among scientists and policy makers that an increased understanding of today's environmental issues requires international collaboration and data synthesis. Meta-analyses have served this role in ecology for more than a decade, but the different experimental...

Fertilization effects on interactions between above-and belowground competition in an old field
Download1999-01-01
Recent theoretical and experimental studies have addressed whether the relative importance of aboveground and belowground competition changes along gradients of biomass productivity. Results have been contradictory, with some researchers finding a decrease in the importance of belowground...
