Innovation and adaptation in the Ontario grape and wine industry: An integrated, transdisciplinary response to climate change

With scientific consensus supporting a 4oC increase in global mean temperature over the next century and increased frequency of severe weather events, adaptation to climate change is critical. Given the dynamic and complex nature of climate change, a transdisciplinary approach toward adaptation can create an environment that supports knowledge sharing and innovation, improving existing strategies and creating new ones. The Ontario wine industry provides a case study to illustrate the benefits of this approach. We describe the formation and work of the Ontario Grape and Wine Research Network within this context, and present some preliminary results to highlight the opportunities for innovation that will drive the successful adaption of the Ontario grape and wine industry.

Plant rhizosphere specificity and variability in the insect and plant adhesins, Madl and Mad2, within the genus Metarhizium suggest plant adaptation as an evolutionary force

Metarhizium is a soil-inhabiting fungus currently used as a biological control agent against various insect species, and research efforts are typically focused on its ability to kill insects. In section 1, we tested the hypothesis that species of Metarhizium are not randomly distributed in soils but show plant rhizosphere-specific associations. Results indicated an association of three Metarhizium species (Metarhizium robertsii, M. brunneum and M. guizhouense) with the rhizosphere of certain types of plant species. M. robertsii was the only species that was found associated with grass roots, suggesting a possible exclusion of M. brunneum and M. guizhouense, which was supported by in vitro experiments with grass root exudate. M. guizhouense and M. brunneum only associated with wildflower rhizosphere when co-occurring with M. robertsii. With the exception of these co-occurrences, M. guizhouense was found to associate exclusively with the rhizosphere of tree species, while M. brunneum was found to associate exclusively with the rhizosphere of shrubs and trees. These associations demonstrate that different species of Metarhizium associate with specific plant types. In section 2, we explored the variation in the insect adhesin, Madl, and the plant adhesin, Mad2, in fourteen isolates of Metarhizium representing seven different species. Analysis of the transcriptional elements within the Mad2 promoter region revealed variable STRE, PDS, degenerative TATA box, and TATA box-like regions. Phylogenetic analysis of 5' EF-Ia, which is used for species identification, as well as Madl and Mad2 sequences demonstrated that the Mad2 phylogeny is more congruent with 5' EF-1a than Madl. This suggests Mad2 has diverged among Metarhizium lineages, contributing to clade- and species-specific variation. While other abiotic and biotic factors cannot be excluded in contributing to divergence, it appears that plant associations have been the driving factor causing divergence among Metarhizium species.

Insights Into the Remembered Educational Experiences of Male Caribbean Immigrants to Canada: Literacy and Identity in the Canadian Classroom

Abstract Past research has addressed the issue of male underachievement in literacy as an issue of global concern. This qualitative study focused on one subgroup of males which the literature highlighted as most at risk of educational underachievement in the Canadian educational landscape: male Caribbean immigrants to Canada. The research questions that framed the study sought to gain insight into the educational experiences of this group of learners so that ways through which their literacy achievement as measured by academic performance and classroom engagement could be projected. New literacy studies view literacy as socioculturally bound in social, institutional, and cultural relationships (Gee 1996). Literacy can therefore be thought of as an extension of self that Lankshear and Knobel (2006) assert is always connected to social identities. Central to the research questions as a result of this perspective was the discovery of the ideologies of reading held by the participants and their connections to literacy practice. Supplementary questions delved into socially valued literacy practices and ways in which learners saw themselves as Black males reflected in the Canadian educational framework. In this qualitative study with an interview design, data were collected through individual semistructured interviews with the 4 participants and through a focus group session with all the participants. The findings depicted that identity, interests, and ideologies of reading all influenced the literacy practices and engagement of Caribbean males. The findings documented are valuable as they provide a fresh perspective surrounding the educational experiences of the male Caribbean learner and can present insights which can lead to enhanced academic engagement and improved student achievement for this group of learners.

Discourses of Masculinity and Femininity in The Hunger Games: "Scarred," "Bloody," and "Stunning"

This article explores how characters in The Hunger Games trilogy are portrayed relative to Connell's gendered discourses of hegemonic masculinity, marginal masculinity, and emphasized femininity. We briefly review the plot of The Hunger Games trilogy and then discuss the ways in which three of the characters are represented with respect to societal gendered discourses, heteronormativity, and the use of violence. We argue that the ways in which these aspects are portrayed relate to the main characters' performance of discourses of hegemonic masculinity (Gale), marginalized masculinity (Peeta), and a complex amalgamation of the two that also draws somewhat on emphasized femininity (Katniss). Finally, we conclude that, while the trilogy could be read as taking a feminist stance with a strong female protagonist, it nonetheless also constrains Katniss in heteronormative ways.

Predicting the Pose of β-Casomorphin-5 and 7 in the Opioid Receptors

The opioid receptors consist of three main subtypes; μ, δ, and κ. Previous binding studies have shown that fragments of the milk protein, β-casein, known as β-casomorphins are agonists of these receptors which are selective for the μ receptor subtype. Using the crystal structures of these three receptors, computational molecular docking studies were done using the software GOLD to determine the conformation of β-casomorphin-5 and 7 when they bind to these three opioid receptors. GOLD was able to discriminate among the three receptors when docking the rigid ligands co-crystalized with the receptors. However, GOLD could not discriminate among the three receptors for either of the highly flexible β-casomorphins. A per amino acid scoring method was developed to overcome this problem. This method was used to predict the conformation of both β-casomorphin-5 and 7 in the μ receptor and determine that the two amino acid residues, Lys303 and Trp318 of the μ receptor are responsible for discriminating among the three receptor subtypes for binding of the β-casomorphin-5 and 7.
