Methane Flux from Drained Northern Peatlands: Effect of a Persistent Water Table Lowering on Flux [PDF]
Measurements of CH4 flux from drained and undrained sites in three northern Ontario peatlands (a treed fen, a forested bog, and a treed bog) were made from the beginning of May to the end of October 1991. In the drained portions, the water table had been

Some peatlands in Central Europe serve as continuous refugia for glacial species, as shown by paleoecological data. However, the ecosystem mechanisms behind this are not well understood. Microclimate plays a key role, and understanding the factors shaping it is crucial for managing peatlands as climate‐change refugia.

Shallow soil moisture – ground thaw interactions and controls – Part 2: Influences of water and energy fluxes [PDF]
The companion paper (Guan et al., 2010) demonstrated variable interactions and correlations between shallow soil moisture and ground thaw in soil filled areas along a wetness spectrum in a subarctic Canadian Precambrian Shield landscape.

Influence of topography and moisture and nutrient availability on green alder function on the low arctic tundra, NT [PDF]
The Arctic has warmed by at least 3°C over the past 50 years and this rapid warming is expected to continue. Climate warming is driving the proliferation of shrubs across the tundra biome with implications for energy balance, climate, hydrology, nutrient

Effect of permafrost thaw on CO2 and CH4 exchange in a western Alaska peatland chronosequence [PDF]
Permafrost soils store over half of global soil carbon (C), and northern frozen peatlands store about 10% of global permafrost C. With thaw, inundation of high latitude lowland peatlands typically increases the surface-atmosphere flux of methane (CH4), a

Experimental Warming Does Not Change Fluctuating Asymmetry in Three Willow Species
We tested whether leaf fluctuating asymmetry (FA) responds to experimental warming in three boreal willow species using open‐top chambers and blind measurements. While warming increased specific leaf area, neither leaf length nor FA showed significant responses, and FA did not differ among species or individuals.

Contrasting Species—Environment Relationships in Communities of Testate Amoebae, Bryophytes and Vascular Plants Along the Fen-Bog Gradient [PDF]
We studied the vegetation, testate amoebae and abiotic variables (depth of the water table, pH, electrical conductivity, Ca and Mg concentrations of water extracted from mosses) along the bog to extremely rich fen gradient in sub-alpine peatlands of the ...

Patterns and determinants of plant- and microbial-derived carbon in alpine peatlands
Abstract Peatlands store approximately one-third of global soil organic carbon (SOC) and clarifying SOC sources is essential to assess soil C formation and stability in these C-rich ecosystems. However, large-scale patterns and drivers of plant- and microbial-derived C remain poorly understood in peatlands.
