Shifts in fungal communities drive soil profile nutrient cycling during grassland restoration

mBio
Soil microbial diversity and community life strategies are crucial for nutrient cycling during vegetation restoration. Although the changes in topsoil microbial communities during restoration have been extensively studied, the structure, life strategies,

Palaeowinds and depositional conditions from Holocene loess in Sweden and Finland

Boreas, EarlyView.
The nature of deglacial and Holocene wind regimes in Fennoscandia is debated, as is the degree to which wind‐blown loess deposits exist in the region. Loess deposits in Fennoscandia are often relatively thin, discontinuous and less well‐sorted than typical loess, and questions remain over the degree of their post‐depositional reworking and the impact ...

Changing climates and environments within the complex Middle to Late Pleistocene fill of an overdeepened valley at Niederweningen, Switzerland

Boreas, EarlyView.
Glacially overdeepened valleys in the northern Alpine Foreland preserve Middle to Late Pleistocene sedimentary sequences that may serve as valuable archives for reconstructing past environmental changes in response to shifts in climate. This study presents a multidisciplinary analysis of two sediment cores from the overdeepened Wehntal Valley at ...

Exogenous melatonin alleviates PEG-induced short-term water deficiency in maize by increasing hydraulic conductance

BMC Plant Biology, 2020
Background Water deficiency is likely to become more frequent and intense as a result of global climate change, which may severely impact agricultural production in the world.

Towards an ‘absolute’ timing of biostratigraphic and environmental phases from the Saalian late glacial to the Weichselian pleniglacial in central Europe—Insights from a lacustrine succession in Lichtenberg, northern Germany

Boreas, EarlyView.
Palynological records are central to the biostratigraphic subdivision of the Late Pleistocene in central Europe. Yet many interglacial and interstadial phases—such as the Eemian, Brörup and Odderade—remain only poorly constrained in time due to limited numerical dating.

An overview of Mass Accumulation Rates in key Polish loess–palaeosol sequences derived from luminescence chronologies

Boreas, EarlyView.
Loess–palaeosol sequences (LPS) represent one of the most important continental archives of late Quaternary environmental change in Europe. Establishing reliable chronologies is essential for reconstructing dust dynamics and for correlating regional loess stratigraphies. In this study, we present the first systematically derived mass accumulation rate (

Deletion of tonB1 in Pseudomonas aeruginosa impairs zinc homeostasis and pathogenicity

Applied and Environmental Microbiology
Many bacterial pathogens must acquire metal ions for proliferation and pathogenesis. In gram-negative bacteria, the TonB system is crucial for nutrient uptake.

Palaeoenvironmental and climatic changes from the lateglacial of the Saalian to the Late Weichselian in central Poland: a multiproxy study from Józefów

Boreas, EarlyView.
Józefów site is a case study which provides a detailed record of environmental and climate changes and confirms the main traces of the landscape morphogenesis of the Late Pleistocene established in central‐eastern Europe. This study presents a multiproxy reconstruction of palaeoenvironment under variable climatic conditions from the retreat of the ...

Breed Selection of Poplars Imposes Greater Selection Pressure on the Rhizosphere Bacterial Community

Microorganisms
Breed selection alters the coevolution of plant–microbiome associations that have developed over long periods of natural evolution. We investigated the effects of breed selection on the rhizosphere microbiomes and metabolites of hybrid parents (I101 and ...

Sediment transport capacity of concentrated flows on steep loessial slope with erodible beds

Scientific Reports, 2017
Previous research on sediment transport capacity has been inadequate and incomplete in describing the detachment and transport process of concentrated flows on slope farmlands during rill development.
