A mesocosm approach to study the response of Sphagnum peatlands to hydrological changes: setup, optimisation and performance [PDF]

open access: yesMires and Peat, 2015
Sphagnum-dominated peatlands are major carbon pools and sinks, but these functions are threatened by climate change. There is, therefore, a need to better understand how microclimatic changes (soil temperature, soil moisture and water table depth) are ...

Concepts of fen and bog re-examined in relation to bryophyte cover and the acidity of surface waters

open access: yesActa Societatis Botanicorum Poloniae, 2014
Studies of surface-water pH and bryophyte assemblages in 440 plots from five peatland regions across northern North America reveal a very distinct, two-fold division into fens with a pH mode at 6.76-7.00, in which Amblystegiaceae are prominent, and bogs ...

Biology of Blattodea and Dermaptera in the Continental Biogeographical Region and Adjacent Areas of European Russia

open access: yesDiversity
(1) Background: Blattodea and Dermaptera in the temperate forest zone include a limited number of species, some of which are widely distributed and common. However, digital data on their biology remains insufficient.

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

open access: yesDrones, 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

Delivering a family‐based child mental health promotion program among two resettled refugee communities during the COVID‐19 pandemic: Lessons learned in a hybrid type II implementation‐effectiveness randomized controlled trial

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract Background Resettled refugee families face elevated mental health risks, compounded by structural and cultural barriers. The Family Strengthening Intervention for Resettlement (FSIR), co‐developed with resettled refugee communities, aims to improve family functioning and child mental health.

Vegetation and vegetation-environment relationships in a muskeg-fen near Thunder Bay, Ontario [PDF]

open access: yes, 1979
This study takes place in an endangered peatland within the city of Thunder Bay Ontario. The study area, William Bog, is one of a few remaining peatlands in the Thunder Bay district which have developed on abandoned Minong phase lake basins on the ...

Hydrology, water chemistry and vegetation characteristics of a tamarack bog in Bath Township, Ohio: Towards restoration and enhancement [PDF]

open access: yes, 2005
The current state of the Bath Tamarack Bog has raised concern about the health and function of the system. Only 6 tamarack (Larix laricina) trees remain, while deciduous trees, particularly red maple (Acer rubrum) and invasive species such as glossy ...

Hydrological self-regulation of domed peatlands in south-east Asia and consequences for conservation and restoration [PDF]

open access: yesMires and Peat, 2010
This article explores the hydrological constraints on the existence of forested peat domes (peat swamp forests) in the humid tropics, the self-regulation mechanisms that enable them to persist and the implications for restoration of damaged domes.

Warming Effects of Spring Rainfall Increase Methane Emissions From Thawing Permafrost

open access: yesGeophysical Research Letters, 2019
Methane emissions regulate the near‐term global warming potential of permafrost thaw, particularly where loss of ice‐rich permafrost converts forest and tundra into wetlands.

Polyhumous Dystrophic Pit Lakes: Hydrographic and Hydrochemical Characteristics on the Example of Reservoirs in the Włoszczowska Basin, Central Poland

open access: yesEnergies, 2022
The article presents the hydrographic and hydrochemical characteristics of post-exploitation reservoirs formed in peat excavations. Two natural bog lakes were selected as the control objects for the study.
