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.

An experimental approach to assess the combined effects of multiple stressors on a large vertebrate species

open access: yesConservation Biology, EarlyView.
Abstract The design of experiments to investigate the combined effects of multiple stressors requires exposing target organisms to multiple combinations of stressor doses. Concurrent manipulation of stressors is often infeasible with wildlife, but long‐lasting health effects allow individual health to be used as an integrator of prior stressor exposure.

Accuracy of ChatGPT, Gemini, Claude and DeepSeek in Carbohydrate Counting

open access: yesDiabetes, Obesity and Metabolism, EarlyView.
ABSTRACT Aims To evaluate the accuracy of four general‐purpose artificial intelligence (AI) models—ChatGPT (OpenAI), Gemini (Google), Claude (Anthropic) and DeepSeek (DeepSeek AI)—in calculating the carbohydrate content of meals compared with clinicians‐calculated reference values.

Quantifying Species‐ and Community‐Level Predation by Carabids on Pests and Beneficials in Wheat and Beet Fields

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Using a model that translates qualitative prey detection data (presence/absence in predator gut contents) into quantitative predation rates, we estimate species‐specific diets of nine carabid species across three cropping contexts (wheat, sugar beet, and fodder beet) for five prey types.

A defensive symbiont and a plant virus confer direct and discrete phenotypes to a cereal aphid in a context‐dependent manner

open access: yesEcological Entomology, EarlyView.
Different BYDV‐PAV isolates exert contrasting effects on aphid fitness, including reproduction and winged production. Different BYDV‐PAV isolates have contrasting effects on aphid dispersal patterns. Aphid feeding behaviour is modulated by the presence of endosymbionts and plant viruses.
