Controls on Soil Organic Matter Degradation and Subsequent Greenhouse Gas Emissions Across a Permafrost Thaw Gradient in Northern Sweden

Frontiers in Earth Science, 2020
Warming-induced permafrost thaw could enhance microbial decomposition of previously stored soil organic matter (SOM) to carbon dioxide (CO2) and methane (CH4), one of the most significant potential feedbacks from terrestrial ecosystems to the atmosphere ...

Regeneration potential of a degraded alpine mountain bog: complex regeneration patterns after grazing cessation and partial rewetting [PDF]

Mires and Peat, 2022
A typical degraded mountain bog in the Swiss Alps was restored by cessation of grazing and partial rewetting. We observed the development of the vegetation over 15 years, starting immediately after the grazing cessation (4 years before rewetting ...

The biocenotic value of Slītere National Park, Latvia, with special reference to inter-dune mires [PDF]

Mires and Peat, 2019
Inter-dune wetlands in Europe harbour many Red List species because they are very nutrient-poor ecosystems. Most of these wetlands are geologically very young and no or little peat formation has occurred.

Comparing UAS LiDAR and Structure-from-Motion Photogrammetry for Peatland Mapping and Virtual Reality (VR) Visualization

Drones, 2021
The mapping of peatland microtopography (e.g., hummocks and hollows) is key for understanding and modeling complex hydrological and biochemical processes. Here we compare unmanned aerial system (UAS) derived structure-from-motion (SfM) photogrammetry and

Regional and local patterns in depth to water table, hydrochemistry and peat properties of bogs and their laggs in coastal British Columbia [PDF]

Hydrology and Earth System Sciences, 2013
In restoration planning for damaged raised bogs, the lagg at the bog margin is often not given considerable weight and is sometimes disregarded entirely.

Regional patterns and controlling factors in plant species composition and diversity in Canadian lowland coastal bogs and laggs [PDF]

Mires and Peat, 2016
Inventories of natural assemblages of plant species are critical when planning ecological restoration of bogs. However, little is known about the regional variation in plant communities at the margins (laggs) of bogs, even though they are an integral ...

Zooplankton under the conditions of lake eutrophication and acidification

Учёные записки Казанского университета: Серия Естественные науки, 2019
Bogging processes are accompanied by the accumulation of humic acids, pH decrease, and low values of oxygen dissolved in water. Environmental conditions that are unfavorable for hydrobionts affect zooplankton communities and change their structure.

Multi-environment factors dominate plant community structure and diversity in an ombrotrophic bog: The water level is the main regulating mechanism

Frontiers in Environmental Science, 2022
Understanding the relationship between vegetation and the environment is critical to manage bog ecosystems. However, information on how environmental factors influence the species composition and diversity in the ombrotrophic bog of Northeast China is ...

Does Shift in Vegetation Abundance After Nitrogen and Phosphorus Additions Play a Key Role in Regulating Fungal Community Structure in a Northern Peatland?

Frontiers in Microbiology, 2022
Soil fungal communities are key players in biogeochemical processes of peatlands, which are important carbon stocks globally. Although it has been elucidated that fungi are susceptible to environmental changes, little is known about the intricate and ...

Check-list and ecology of Sphagnum mosses (Sphagnaceae) in the Republic of Mordovia (Russia)

Nature Conservation Research: Заповедная наука, 2020
Sphagnaceae are an important component of ecosystems. In the forest-steppe zone, where the Republic of Mordovia (Russia) is located, many of these mosses are situated at the edge of the species range.
