Evaluating Testability of Permafrost Models Through Physical and Thermal Testing in Complex Mountain Terrain, Yukon, Canada

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Due to its subsurface nature, permafrost cannot be directly observed with the naked eye or optical remote sensing. Consequently, accurately describing its distribution and thermal state is challenging. This is especially true in vast, remote environments, where obtaining comprehensive field data is demanding or improbable.

The ultrastructure of epidermal surface of stem and branch internods and spores of horsetails of subgenus Equisetum (Equisetum L., Equisetaceae)

Turczaninowia, 2016
Ultrastructure of epidermal surface of stems and branches internodes of 5 species and 3 interspecific hybrids were studied using scanning electron microscopy, as well as spore surface of 5 species of horsetail subgenus Equisetum (Equisetum, Equisetaceae):

Micro‐habitat selection by boreal woodland caribou improves access to food

Wildlife Biology, EarlyView.
Bio‐logging sensors attached to radiotelemetry receivers have great potential to transform our understanding of the ecological, physiological, and energetic constraints that shape patterns of wildlife movement under field conditions. We used video camera collars to assess microhabitat selectivity by woodland caribou Rangifer tarandus in boreal forests ...

Short‐term soil responses and site conditions to inverted mounding on peatland linear features in Alberta, Canada

Restoration Ecology, EarlyView.
Abstract Introduction Seismic lines represent one of the most extensive and persistent anthropogenic disturbances in boreal peatlands, limiting forest regeneration and altering key ecosystem functions. Inverted mounding is increasingly applied to elevate planting microsites above shallow water tables, yet evidence on short‐ to medium‐term biophysical ...

THE ANATOMY OF A HYBRID EQUISETUM

American Journal of Botany, 1915
The genus Equisetum has been the object of a considerable amount of study on the part of a great many botanists. As a rule, each has chosen certain features for especial investigation, with the result that each has adopted a different scheme of classification depending on what characters he himself deemed of most significance.

No need to seed: restoring species‐rich grassland on former arable fields by natural regeneration

Restoration Ecology, EarlyView.
Abstract Introduction Over the last century, agricultural intensification has caused substantial losses of semi‐natural species‐rich grasslands. One means of restoring grassland habitat is to abandon farmed land, followed by mowing and/or grazing of the established vegetation to facilitate meadow diversification. Objectives This study investigated post‐

Alcoholic extracts of Russian sage (Salvia yangii) contain bioactive terpenoids with inhibitory activity against grapevine downy mildew (Plasmopara viticola)

Pest Management Science, Volume 82, Issue 9, Page 8159-8170, September 2026.
Alcoholic extracts from flowers, leaves, and shoots of Russian sage decreased downy mildew severity on grapevine leaf disks. Fractionation followed by metabolomic analysis revealed putative terpenoids as the main components of the active fractions. Specifically, 7‐methylrosmanol, 12‐O‐methylcarnosic acid, carnosic acid, and carnosol were identified as ...
