A standardized permafrost ground temperature collection for Canada 2025

Abstract. Ground temperature is an essential variable for monitoring the thermal state of permafrost, developing models, and conducting fundamental research. However, the usability of GT data in Canada is often hampered by inconsistent file formats, a lack of metadata standardiza...

The frequency of spawning and skipped migration in a central Canadian population of anadromous Arctic char inferred using acoustic telemetry

Understanding spawning frequency and migration behaviour is essential for managing iteroparous anadromous fishes such as Arctic char (Salvelinus alpinus). Using a decade of acoustic telemetry data from southern Victoria Island, Nunavut, we examined the frequency of marine migrati...

Multi-year Assessment of Smolt Migrations in a Large, Fragmented River : Hydropower and the Remnant Wild Atlantic Salmon (Salmo salar) of the River Dalälven

Anthropogenic river modifications can impede diadromous fish migration and passage success. We investigated downstream passage probabilities, migration speeds, and route selection of wild Atlantic salmon smolts in the lower 28 km of the river Dalälven, Sweden, where two hydroelec...

A collaborative e-library for stressor-response functions to improve the science underlying salmonid management

Stressor-response functions quantify relationships linking environmental stressors to biological responses, underpinning salmonid life-cycle models, restoration planning, regulatory policy, and cumulative effects assessments. Despite their importance, these stressor-response func...

Eruption source parameters for a Canadian mafic explosive eruption: an example from Sii Aks (Tseax) volcano

Abstract Observations from tephra fall deposits are needed to constrain input parameters used to model tephra fall hazard, but this is challenging for mafic Canadian volcanoes, which are often in remote locations. Here, we present eruption source parameters (ESPs) for the approxi...
