Wildfires in permafrost areas, including smoldering fires (e.g., “zombie fires”), have increasingly become a concern the Arctic and subarctic. Their detection is difficult requires ground truthing. Local Indigenous knowledge are becoming useful sources of information that could guide future research wildfire management. This paper focuses on peatland Siberian subarctic taiga linked to local com...

The benthic macrofauna of Arctic and subarctic seas is mainly represented by widespread species generally devoid endemics. exceptions are reduced habitats, such as cold seeps, hydrothermal areas, wood falls, which include endemics at least the level. A detailed study analysis allows us to understand mechanisms colonization assess age fauna high-latitude marine regions. Here, new Provanna annae ...

1. Plant production in subarctic peatlands is nitrogen (N)-limited. Climate warming increases N mineralization in superficial peat layers and recent results additionally show that permafrost thawing in these peatlands may substantially increase plant-available N at the thaw front. This might stimulate net primary production and affect species composition. However, the ability of individual peat...

Subarctic forest-tundra ecotones dominated by mountain birch (Betula pubescens ssp. czerepanovii) are an important habitat for semi-domestic reindeer Rangifer tarandus. The seasonal timing of grazing may direct vegetation trajectories in these systems, because the summer ranges, birches subjected to browsing, while winter feed on understorey and arboreal lichens but leave intact. Based earlier ...

The Western Subarctic Gyre (WSG) is a cyclonic upwelling gyre in the northwest subarctic Pacific, which region with high concentration of nutrients but low chlorophyll. We investigated community structure and spatial distribution phytoplankton this area by using HPLC-pigment CHEMTAX (a chemotaxonomy program) metabarcoding sequencing during summer 2021. showed significant differences between two...
