Translocation and deterrence as tools for conservation and management of Columbian ground squirrels (Urocitellus columbianus) in a national park

open access: yesEcological Solutions and Evidence, Volume 7, Issue 2, April–June 2026.
Our study evaluates two non‐lethal methods for managing Columbian ground squirrels in Jasper National Park, Alberta, Canada. We demonstrate that translocated squirrels exhibited lower survival than controls and that a deterrence methodology that includes blocking burrows may be an appropriate alternative, especially when combined with other tools ...

Glycerol carbonate formation from glycerol and dimethyl carbonate using lithium‐based catalysts

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 4, Page 1743-1754, April 2026.
Abstract Excess glycerol from biodiesel production can be sustainably converted into value‐added products like glycerol carbonate, for its use in polymers, solvents, and as ecofriendly alternative as green chemical in various chemical industries. This study aims to synthesize a catalyst optimized for the glycerol and dimethyl carbonate (DMC) conversion

Hypolimnetic anoxia in oligotrophic lakes and its effects on nutrient supply and phytoplankton communities

open access: yesEcosphere, Volume 17, Issue 4, April 2026.
Abstract Low concentrations of dissolved oxygen (DO) in hypolimnetic waters are becoming more common and could affect nutrient supplies available to phytoplankton communities in meso‐ and eutrophic lakes. We examined the connections among hypolimnetic DO, nutrient concentrations, and phytoplankton communities in 26 oligotrophic lakes in the Kawartha ...

Seasonal stoichiometry of terrestrial consumer–resource interactions

open access: yesEcology, Volume 107, Issue 4, April 2026.
Abstract Variation in producer stoichiometry influences animal distribution, abundance, and behavior. While spatial variation in producer stoichiometry is widely acknowledged, seasonal variation in producer nutrient content may also strongly affect primary consumers.

Challenged by a Climate Oscillation: Hydrology and Management of a Terminal Lake and Wetland Through the 20th Century

open access: yesHydrological Processes, Volume 40, Issue 4, April 2026.
Situated in Alberta, Canada, Frank Lake is a terminal or endorheic lake that supports prolific waterfowl and other wildlife and remediates municipal and agro‐industrial wastewater. The lake periodically rose and fell over the past century and the correspondences with climate, weather and management revealed the predominant correspondence with the ...

Mapping Future Coastal Groundwater Flooding and Impacted Infrastructure Using a Hybrid Analytical–Geospatial Approach

open access: yesHydrological Processes, Volume 40, Issue 4, April 2026.
Groundwater flooding and onsite wastewater treatment system (OWTS) inundation due to sea‐level rise. ABSTRACT Surface flooding from rising sea levels is widely recognised as a coastal threat, but coastal subsurface (groundwater) flooding is often overlooked.

Testing Hypotheses of Covariate Effects on Topics of Discourse

open access: yesStatistical Analysis and Data Mining: An ASA Data Science Journal, Volume 19, Issue 2, April 2026.
ABSTRACT We introduce an approach to topic modeling with document‐level covariates that remains tractable in the face of large text corpora. This is achieved by de‐emphasizing the role of parameter estimation in an underlying probabilistic model, assuming instead that the data come from a fixed but unknown distribution whose statistical functionals are

Humains, bovins et prairies naturelles : une histoire commune de réciprocité et d'échange marchand [PDF]

open access: yes
Le projet de recherche entend contribuer a la compréhension des transformations de l’élevage en Uruguay à partir de l’analyse anthropologique et microsociologique des relations humains-écosystème-animaux et des différents types de connaissances associés aux modèles de développement proposés par les politiques publiques depuis le XX siècle.

Une nouvelle approche pour caractériser les prairies naturelles et leur valeur d'usage

open access: yes, 2002
Le conseil technique pour la gestion des prairies naturelles ou semi-naturelles se heurte depuis longtemps à la difficulté de mise en oeuvre de méthodes basées sur l'étude floristique de la végétation. Très consommatrice en temps, nécessitant une bonne connaissance en botanique et peu généralisables, ces méthodes sont peu appliquées par les conseillers
