Earth Surface Processes and Landforms, Volume 51, Issue 10, October 2026.Large wood (LW) plays a key role in river dynamics and biodiversity, but quantifying its volume and budget remains challenging. This study compared in situ and UAV‐based measurements of LW jams in two Gaspé Peninsula rivers (Québec, Canada), highlighting strong variability mainly due to operator bias. A new methodology reduced this variability, leading

Variation in Male Fertilities and Pairwise Mating Probabilities in Picea glauca [PDF]
Genetics, 1987 ABSTRACT Frequencies of multilocus male gametes in seeds collected from clones in several blocks of a white spruce seed orchard were analyzed as part of a 2-yr study of mating system variation in this species. Observed frequencies of male gamete types departed significantly from those expected assuming equal male fertilities among clones.

Journal of Quaternary Science, Volume 41, Issue 7, Page 1178-1199, October 2026.ABSTRACT Subfossil insect communities from the Quartz Creek site provide a detailed record of both Late Pleistocene steppe–tundra and Holocene boreal forest ecosystems in central Yukon Territory, Canada. Fifteen Pleistocene assemblages (marine isotope stages [MIS] 4 to 2) are dominated by steppe–tundra and dry‐tundra taxa, particularly the weevils ...

Internal Structure, Kinematics, and Prehistory of Frozen Debris Lobe‐A (FDL‐A), Brooks Range, Alaska
Permafrost and Periglacial Processes, Volume 37, Issue 4, Page 645-667, October/December 2026.ABSTRACT Frozen Debris Lobe‐A (FDL‐A)—one of hundreds of FDLs in the Brooks Range of northern Alaska—is a slow‐moving landslide in permafrost that has been the subject of research since 2008 due to its close proximity to the Dalton Highway. Here, we synthesize more than a decade's worth of climate and surface measurements of monitored FDLs, and the ...

AGU Advances, Volume 7, Issue 7, October 2026.Abstract Northern permafrost landscapes are undergoing rapid warming and thaw, yet the three‐dimensional subsurface structure that governs thaw vulnerability and landscape response remains poorly resolved by conventional ground temperature monitoring and satellite remote sensing.

Journal of Applied Ecology, Volume 63, Issue 10, October 2026.While management in the oil sands typically focuses on the amount of habitat lost and looks to ‘spatial offsets’ of undisturbed habitat elsewhere as a solution, we demonstrate that both composition and spatial configuration must be considered on appropriate spatial scales when developing land‐use strategies in patchy ecosystems undergoing anthropogenic

Journal of Ecology, Volume 114, Issue 10, October 2026.This study demonstrates that specific ectomycorrhizal fungal taxa are associated with trade‐offs between greater tree growth and reduced soil carbon concentrations in boreal forests. This work presents field‐based evidence consistent with the emerging understanding that ectomycorrhizal fungi influence ecosystem carbon stocks through the enzymatic ...
