Seasonal patterns and controls on net ecosystem CO2 exchange in a boreal peatland complex [PDF]

, 1998
We measured seasonal patterns of net ecosystem exchange (NEE) of CO2 in a diverse peatland complex underlain by discontinuous permafrost in northern Manitoba, Canada, as part of the Boreal Ecosystems Atmosphere Study (BOREAS).

A taxanomic study on sections Montanae, Limosae, and Paniceae of Carex L. in Korea(Cyperaceae)

Korean Journal of Plant Taxonomy, 2003
Morphological characters of sections Montanae (one taxon), Limosae (one taxon) and Paniceae(seven taxa) of genus Carex (Cyperaceae) were reexamined. The epidermal patterns of perigynium, achene and leaf were investigated using by a scanning microscope (SEM) and a light microscope (LM).

Nomenclature and typification of sectional names in Carex (Cyperaceae)

TAXON, Volume 74, Issue 6, Page 1543-1568, December 2025.
Abstract This paper presents an updated survey of all the published names at the section rank in Carex and its formerly accepted satellite genera. We included related names at other ranks when relevant. We address validity, legitimacy, priority, typification, and – if relevant – synonymy.

Annual Vegetation of Saline Seasonal Wetlands (Crypsietea aculeatae) in Europe

Applied Vegetation Science, Volume 28, Issue 4, October/December 2025.
The first continent‐wide classification of the Crypsietea aculeatae vegetation is presented, defining one phytosociological alliance and four associations. Vegetation variability is mainly driven by climate parameters and soil properties (salinity, soil moisture, soil acidity, nutrient availability).

Year‐Round δ13C‐CH4 Reveals Seasonal Transition in Methane‐Related Processes in a Boreal Mire

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 9, September 2025.
Abstract While boreal mires are known to be a significant natural source of methane (CH4), the seasonality of the related processes and their controls are still poorly understood. Here we aim to characterize CH4 production, oxidation and transport, and their drivers in a boreal mire using year‐round continuous measurements of stable carbon isotope ...

Interacting Sea‐Level Rise, Sea‐Ice Loss, Storm Flooding, Erosion, and Permafrost Thaw Threaten Ecosystems, Wildlife, and Communities on the Yukon‐Kuskokwim Delta

Earth's Future, Volume 13, Issue 8, August 2025.
Abstract The Yukon‐Kuskokwim Delta has the largest intertidal wetland in North America, is a globally critical breeding area for waterbirds, and is home to the largest regional indigenous population in the Arctic. Here, coastal tundra ecosystems, wildlife, and indigenous communities are highly vulnerable to sea‐ice loss in the Bering Sea, sea‐level ...
