Open AccessExploring polyphosphates in soil: presence, extractability, and contribution to microbial biomass phosphorus
Polyphosphates (Poly-P) are known to fulfil several important physiological functions. Many microorganisms can accumulate large amounts of Poly-P in their biomass. Regardless of these facts, systematic researc...

Open AccessUndeveloped till soils in scree areas are an overlooked important phosphorus source for waters in alpine catchments
Scree deposits in alpine catchments contain undeveloped till soils that are “hidden” between and under stones. These scree areas have no vegetation except for sparse lichen patches on stone surfaces, but the s...

Biochemical inhibition of acid phosphatase activity in two mountain spruce forest soils
The product inhibition of the 4-methylumbelliferyl phosphate (MUB-P) decay rate, a measure of potential acid phosphatase activity, has not been considered in most of the published kinetic studies. The aim of t...

A plant–microbe interaction framework explaining nutrient effects on primary production
In most terrestrial ecosystems, plant growth is limited by nitrogen and phosphorus. Adding either nutrient to soil usually affects primary production, but their effects can be positive or negative. Here we pro...

In situ phosphorus dynamics in soil: long-term ion-exchange resin study
Phosphorus (P) availability to soil biota is commonly determined using soil extraction methods, which can mobilise unclearly specified and stable soil P fractions. Alternatively, natural P availability can be ...

Potential carbon emissions dominated by carbon dioxide from thawed permafrost soils
A meta-analysis of soil incubation studies from the permafrost zone suggests that thawing under aerobic conditions, which releases CO2, will strengthen the permafrost carbon feedback more than waterlogged systems...

Open AccessPlant-derived compounds stimulate the decomposition of organic matter in arctic permafrost soils
Arctic ecosystems are warming rapidly, which is expected to promote soil organic matter (SOM) decomposition. In addition to the direct warming effect, decomposition can also be indirectly stimulated via increa...

Main photoautotrophic components of biofilms in natural draft cooling towers
While photoautotrophic organisms are an important component of biofilms that live in certain regions of natural draft cooling towers, little is known about these communities. We therefore examined 18 towers at...
