Disentangling root system responses to neighbours: identification of novel root behavioural strategies
Download2015-01-01
Plants live in a social environment, with interactions among neighbours a ubiquitous aspect of life.Though many of these interactions occur in the soil, our understanding of how plants alter root growth and the patterns of soil occupancy in response to neighbours is limited. This is in contrast...

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...

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....

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...

Rapid Increases in Forest Understory Diversity and Productivity following a Mountain Pine Beetle (Dendroctonus ponderosae) Outbreak in Pine Forests
Download2015-01-01
Pec, G. J., Karst, J., Sywenky, A. N, Cigan, P. W., Erbilgin, N., Simard, S. W., Cahill, J. F.
The current unprecedented outbreak of mountain pine beetle (Dendroctonus ponderosae) in lodgepole pine (Pinus contorta) forests of western Canada has resulted in a landscape consisting of a mosaic of forest stands at different stages of mortality. Within forest stands, understory communities are...

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,...

Scaling Disturbance Instead of Richness to Better Understand Anthropogenic Impacts on Biodiversity
Download2015-01-01
Mayor, S. J., Cahill, J. F., He, F., Boutin, S.
A primary impediment to understanding how species diversity and anthropogenic disturbance are related is that both diversity and disturbance can depend on the scales at which they are sampled. While the scale dependence of diversity estimation has received substantial attention, the scale...
