Abiotic and biotic factors influencing host-plant use of a generalist herbivore through plant-mediated interactions: oviposition and larval performance by the bertha armyworm, Mamestra configurata Walker (Lepidoptera: Noctuidae) on canola
DownloadFall 2018
The bertha armyworm (BAW), Mamestra configurata Walker (Lepidoptera: Noctuidae), is a native, polyphagous herbivore which feeds on a variety of plants in different families. In the Prairie Provinces, canola, Brassica napus L. (Brassicaceae), is a preferred host, making BAW a significant pest....

An assessment of the fumigant metam sodium and a Brassica juncea-derived biofumigant as management tools for clubroot (Plasmodiophora brassicae) of canola (Brassica napus)
DownloadFall 2016
Clubroot of crucifers, caused by the soilborne parasite Plasmodiophora brassicae, is spreading across canola (Brassica napus) fields in Alberta, Canada. Dissemination of the parasite is associated with the movement of infested soil on farm and other machinery, with the disease generally...

Rutabaga (Brassica napus ssp. napobrassica (L.) Hanelt) is widely grown as a vegetable crop and animal fodder, and is reported to be an excellent source of clubroot (Plasmodiophora brassicae) resistance genes. In this study, the genetic diversity and clubroot resistance of 124 rutabaga accessions...

Canada’s boreal forest is the breeding ground for some 288 species of resident and migratory birds. Approximately 65% of the species that are currently of highest conservation priority in the boreal region are associated with wetlands and riparian areas. Although estimates vary with scale and...

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...

Effect of modulation of auxin response on clubroot development caused by Plasmodiophora brassicae in Arabidopsis
DownloadSpring 2024
Clubroot disease caused by the obligate biotrophic protist Plasmodiophora brassicae, is a serious soilborne disease in Brassicaceae species including cruciferous crops such as canola and the genetic model species Arabidopsis. This disease, identified by the formation of sizable root galls, is...

Fall 2021
Plasmodiophora brassicae Wor. is a soilborne parasite causing clubroot of canola (Brassica napus L.), a serious disease managed mostly by planting clubroot resistant (CR) cultivars. Recently, new pathotypes of P. brassicae have emerged that overcome resistance, highlighting the need for a greater...

Factors influencing Plasmodiophora brassicae resting spore loads in soil and clubroot disease severity in canola (Brassica napus)
DownloadSpring 2015
Clubroot, caused by Plasmodiophora brassicae, is an important soilborne disease of Brassica napus canola. Studies were conducted to increase understanding of the impact of various soil parameters and crop rotation regimes on P. brassicae inoculum levels and clubroot severity, respectively. In...

The expansion of the human footprint across the world is increasing the number of interactions between humans and wildlife. Many studies have quantified wildlife behavioural responses to humans, as this is an active area of research with practical implications for species conservation. Animal...

Functional diversity is an important concept in community ecology because it captures information on functional traits absent in measures of species diversity. One popular method of measuring functional diversity is the dendrogram-based method, FD. To calculate FD, a variety of methodological...
