Abstract:
... Hardgrounds from the Upper Ordovician strata of eastern Laurentia exhibit a wide range of morphologies, though the development of their complex surface topographies remains poorly understood. These early lithified seafloors, which can be laterally very extensive, may provide key information about basin dynamics and global ocean fluctuations. Based on spectacular exposures and newly-excavated mater ...

Abstract:
... Food sovereignty scholars are increasingly re-conceptualizing sovereignty by accounting for its diverse expressions across space according to specific histories, identities, and local socio-ecological realities and dynamics. In grappling with the multiple bases of sovereignty, attention has been directed toward Indigenous food sovereignty in North America. Specifically, food scholars are examining ...

Abstract:
... Winery wastewater generated during vinification is often co-treated with the municipal wastewater at the biological sections of the municipal wastewater treatment plants prior to its discharge into the environment, and the grey water footprint associated with these discharges are often neglected from water footprint assessments of the wine-making process. This study presents a method for assessing ...

Abstract:
... While still a relatively niche product, skin-contact wines (commonly called ‘orange’, ‘skin-contact white’ or ‘amber’ wines) have re-emerged as a new global wine category. To our knowledge, only two jurisdictions have adopted regulatory criteria to define these wines. In 2015, South Africa amended its regulations and became the first wine region to legally define skin-contact wines as ‘Skin macera ...

We label these ...

Abstract:
... Mysis diluviana is a major component of prey fish diets in the Great Lakes, so annual production of M. diluviana is important for understanding and modeling energy flow through Great Lakes food webs. However, only three lake-wide measurements of M. diluviana annual production in Lake Ontario are currently available (1971, 1990, 1995). During 2013, lake-wide coverage of Lake Ontario was achieved du ...

CONTEXT: To detect an effect of landscape context on a species’ response, the landscape variables need to be measured within the appropriate distance from the species’ response, i.e. at the scale of effect. However, it is not clear what factors determine the scale of effect. OBJECTIVE: Our objective was to test the prediction that the scale of effect should be smallest when the species’ response i ...
