The Effect of Nitrogen and Phosphorus Fertilization on Plant Community Along Chronosequences of Reclaimed and Unreclaimed Postmining Soils After Coal Mining

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Nitrogen and phosphorus availability drive plant community composition, productivity, and ecosystem functioning. During succession, nutrient availability typically changes as organic matter accumulates in the soil, influencing both nitrogen and phosphorus pools. We assessed nutrient limitation along postmining chronosequences (10–50 years old),

Cotton strips as a model substrate for analysis of leaf‐litter‐colonizing microbial assemblages in streams

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Leaf‐litter decomposition is a key indicator of the functional integrity of stream ecosystems and cotton strips have been employed as a standard substrate for quantification of litter‐decomposition rates in streams across the globe. Cotton strips also offer a standardized method for assessing structural integrity of stream microbial ...

Storage treatment and diluent cause inconsistencies in commonly used fluorometric microplate enzyme assays conducted with saltmarsh soils

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Fluorometric enzyme assays are a tool for determining potential enzyme activity in soils. A wide array of methodological approaches is adopted by different studies, making comparisons difficult. An important consideration is whether assay conditions replicate the environment of the samples or optimize potential enzyme activity.

Introducing a ramped pyrolysis/oxidation‐14CO2 analysis system operated with mobile molecular sieve traps

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract A novel instrument for the thermal degradation of sedimentary organic matter was set up at the Alfred Wegener Institute (AWI) in Bremerhaven, Germany, with the aim of enabling Ramped Pyrolysis/Oxidation‐14C analysis as direct CO2 gas measurement.

Asynchronous population trends stabilize mesopredatory coral reef fish communities in the face of global change

open access: yesOikos, EarlyView.
Biodiversity can underpin stability in communities, allowing them to withstand environmental fluctuations without changes in aggregate properties like total abundance or biomass. We investigated the influence of biodiversity on two crucial population‐level mechanisms governing abundance stability in mesopredatory coral reef fishes: 1) ‘community ...
