Direct and indirect drivers of plant diversity responses to climate and clipping across northern temperate grassland
Download2014-01-01
Cahill, James F., Bork, Edward W., White, Shannon R.
It is well known that climate can influence plant community assembly via a multitude of indirect and direct pathways. However, interpretations of plant diversity responses to simulated climate change experiments, and subsequent predictions of plant communities under future climate scenarios,...

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...

Disruption of a belowground mutualism alters interactions between plants and their floral visitors
Download2008-01-01
Cahill, J. F., Shore, B. H., Smith, G. R., Elle, E.
Plants engage in diverse and intimate interactions with unrelated taxa. For example, aboveground. oral visitors provide pollination services, while belowground arbuscular mycorrhizal fungi (AMF) enhance nutrient capture. Traditionally in ecology, these processes were studied in isolation,...

Disturbance has lasting effects on functional traits and diversity of grassland plant communities
Download2022-01-01
Ellen A Smith, Emily M Holden, Charlotte Brown, James F Cahill Jr
Background Localized disturbances within grasslands alter biological properties and may shift species composition. For example, rare species in established communities may become dominant in successional communities if they exhibit traits well-suited to disturbance conditions. Although the idea...

McNickle, G. G., Deyholos, M. K., Cahill Jr, J. F.
Background Ecologists recognize that plants capture nitrogen in many chemical forms that include amino acids. Access to multiple nitrogen types in plant communities has been argued to enhance plant performance, access to nitrogen and alter ecological interactions in ways that may promote...

2012-01-01
Ideas about how plant competition varies with productivity are rooted in classic theories that predict either increasing (Grime) or invariant (Tilman) competition with increasing productivity. Both predictions have received experimental support, although a decade-old meta-analysis supports...

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...

Karst, J., Cahill, J. F., Lyons, D.
This paper is the product of a seminar led by JC Cahill in response to a request by many graduate students and post-docs in our department to teach effective writing strategies. Rather than go over the mechanics of writing, JC introduced the concept of “pitch” and its importance in scientific...

Flowering and floral visitation predict changes in community structure provided that mycorrhizas remain intact
Download2018-01-01
Pollination is critical for plant fitness and population dynamics, yet little attention is paid to the role of flowering and plant-pollinator interactions in structuring plant communities, including community responses to environmental change. Changes in arbuscular mycorrhizal fungi (AMF),...

Independent evolution of leaf and root traits within and among temperate grassland plant communities
Download2011-01-01
In this study, we used data from temperate grassland plant communities in Alberta, Canada to test two longstanding hypotheses in ecology: 1) that there has been correlated evolution of the leaves and roots of plants due to selection for an integrated whole-plant resource uptake strategy, and 2)...
