Environmentally adjusted productivity growth and shadow prices for dairy farms

open access: yesCanadian Journal of Agricultural Economics/Revue canadienne d'agroeconomie, EarlyView.
Abstract We estimate the environmentally adjusted productivity growth and shadow price for Ontario dairy farms. We use an input‐oriented directional distance function and farm‐level data from 2000 to 2020. First, we find that while GHG emissions per cow increase with higher milk yields, emission intensity decreases as milk yield per cow increases.

Level of knowledge and perceptions of Canadians on supply management

open access: yesCanadian Journal of Agricultural Economics/Revue canadienne d'agroeconomie, EarlyView.
Abstract Supply management (SM) has recently attracted a lot of attention nationally and internationally. A bill (C‐202) to safeguard SM from future international trade negotiations was voted unanimously by the Canadian parliament in 2025. At the international level, tariffs associated with SM have been criticized by the Trump administration.

Interplay of crop diversity and agricultural area in agroecosystem services: Analytical and empirical study on local water quality

open access: yesCanadian Journal of Agricultural Economics/Revue canadienne d'agroeconomie, EarlyView.
Abstract This study expands the framework for analyzing the interplay of agricultural area and crop diversity on agroecosystem services by incorporating the species‐area relationship concept from biology. We estimate panel fixed effects models that include both agricultural area and crop diversity, along with their interaction term.

Impact of Host and Food Availability on Life‐History Traits in Six Egg Parasitoid Species of the Genus Trichogramma

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
In this study we measured the impact of access to sugar and hosts on the longevity and fecundity of six Trichogramma species: T. cacoeciae, T. chilonis, T. minutum, T. leptoparameron, T. pintoi and T. sibericum. The impact of food differed among species, but there was a general tendency of increased life expectancy and potential fecundity with sugar ...

Genetic and Ecological Management of Pacific Salmon Fisheries for the 21st Century

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Based on ecological adaptation theory, tremendous effort is being spent on measures that are eliminating salmon hatcheries and fishing opportunities with the intention of protecting wild runs deemed to be of particular genetic importance to the survival of the species.

A Lavandula angustifolia flower extract and dipeptide‐4 blend modulates oxidative, glycative, autophagic and circadian pathways in human skin models

open access: yesInternational Journal of Cosmetic Science, Volume 48, Issue 3, Page 477-488, June 2026.
The blend enhanced antioxidation, anti‐glycation, autophagy and circadian regulation in cell and skin models. Key markers included mitochondrial ROS, γ‐H2AX, AGEs, ATP, melatonin, LC3 and SOD. Significant improvements were visualized via fluorescence and quantified with statistical markers.

Investigation into the delivery and evaluation of a unique Avena sativa (Oat) Lipid Extract on skin barrier using LC‒MS/MS, Raman spectroscopy, immunostaining analysis and skin efficacy

open access: yesInternational Journal of Cosmetic Science, Volume 48, Issue 3, Page 500-517, June 2026.
Abstract Objectives Oat lipids are rich in ceramides. In this investigation, we analysed the delivery of a specific Oat Lipid Extract derived from Avena sativa, comprising ‘skin identical’ ratios of fatty acids, ceramides and cholesterol/sterol. This investigation is the first reported investigation of oat lipids utilizing Raman spectroscopy for the ...
