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...

Limited impacts of extensive human land use on dominance, specialization, and biotic homogenization in boreal plant communities

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....

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...

Fagan, W. F., Jin, Y., Bishop, J. G., Marleau, J. M., Lewis, Mark A.
The relative importance of plant facilitation and competition during primary succession depends on the development of ecosystem nutrient pools, yet the interaction of these processes remains poorly understood. To explore how these mechanisms interact to drive successional dynamics, we devised a...

Inquiring into the Roles and Responsibilities of Facilitating Loose Parts Play: A Practitioner's Perspective
DownloadSpring 2021
Play, and more specifically unstructured outdoor play, is well-documented as being beneficial, and arguably essential to healthy cognitive, emotional, social and physical development. However, factors such as risk, liability and self-regulation often complicate and deter unstructured outdoor play...

The worldwide biodiversity crisis has intensified the need to better understand how biodiversity and human disturbance are related. Yet this relationship lacks both consensus in theoretical expectations and consistency in observed empirical patterns. I present one of the largest extent studies...

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...

We examined the relationship between aspen cover and understory production across two topographic positions and two management systems within the Aspen Parkland of eastern Alberta. Understory biomass typically declined with increasing overstory, with greater yield losses on north-facing forests...

Profetto-McGrath, J., Campbell, T. D.
Purpose/Objectives: The purposes of this article were to describe the challenges that clinical nurse specialists (CNS) face in their role and to examine how CNSs describe the skills and attributes that are needed to promote the use of evidence-based practice (EBP) in their workplaces. This...
