Beyond our backyard: Unravelling how social‐ecological fit drives the formation of inter‐regional collaborative networks for water governance in the Yellow River Basin

open access: yesPeople and Nature, EarlyView.
Abstract The societal and biophysical permeability across human‐demarcated jurisdictions within watersheds necessitates collaboration among administrative regions. The effectiveness of such collaboration is partly determined by the degree to which institutional arrangements align with underlying social and ecological interdependencies, a concept ...

Lumineszenz-Datierung der Löss-Paläoboden-Sequenz in der Kiesgrube Gaul/Weilbach, Südhessen [PDF]

open access: yes, 2011
A thick Middle and Late Pleistocene loess/palaeosol sequence is exposed at the gravel quarry Gaul located east of Weilbach in the southern foreland of the Taunus Mountains. The loess/palaeosol sequence correlates to the last three glacial cycles.

Implementing potential climate‐smart practices through diverse partnerships

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Climate change is one of the greatest threats to society, negatively impacting agriculture and crop yields. Globally, agriculture is also one of the largest greenhouse gas (GHG) emitting sectors. Climate‐smart practices that are developed through diverse partnerships with scientists and practitioners are needed to decrease GHG emissions. We implemented

Clay Mineralogy of Red Clay Deposits from the Central Carpathian Basin (Hungary): Implications for Plio/Pleistocene Chemical Weathering and Paleoclimate [PDF]

open access: yes, 2013
Geochemical and mineralogical studies of palaeosols provide essential information for palaeoclimatic and palaeoenvironmental interpretation of continental deposits and can present a proxy for palaeoclimate.

Deep‐Circulating Groundwater From the Tibetan Plateau Constructed the Loess Plateau

open access: yesGeophysical Research Letters
AbstractChina's Loess Plateau (LP) is a quintessential example of a desert transitional environment characterized by a distinctive soil profile comprising of a red clay layer overlain by loess. The source of the sedimentary materials that formed the plateau, as well as the mechanism for the red clay/loess transition, are yet unexplained.

Root exudates mediate microorganisms to improve rhizosphere nutrient availability and crop productivity under straw mulching and slow‐release nitrogen fertilizer

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Root exudates play a key role as signals and nutrients in mediating plant–microbe communication. However, critical knowledge gaps remain regarding how root exudates mediate soil–microbe–plant interactions to regulate crop yield under long‐term straw mulching combined ...

Marine tephrochronology: a personal perspective [PDF]

open access: yes, 2014
This special volume on marine tephrochronology is remarkable, and timely, because it marks a concerted step towards what might be informally termed ‘phase 3’ of a revolution in Quaternary geosciences that began around 40 years ago.

Depth‐dependent mechanisms regulate accumulation of plant‐ and microbial‐derived residues under long‐term nitrogen addition in a semiarid grassland

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant‐ and microbial‐derived residues constitute the primary sources of soil organic carbon (SOC) in grassland ecosystems. However, their differential responses to chronic nitrogen (N) enrichment and the depth‐dependent mechanisms governing their accumulation remain ...

Deletion of tonB1 in Pseudomonas aeruginosa impairs zinc homeostasis and pathogenicity

open access: yesApplied 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.

The relationships and sensibility of wheat C:N:P stoichiometry and water use efficiency under nitrogen fertilization

open access: yesPlant, Soil and Environment, 2015
A field study was conducted to investigate the variations in the carbon:nitrogen:phosphorus (C:N:P) stoichiometry of winter wheat (Triticum aestivum L.) and its relationships with wheat growth rate (r) and water use efficiency (WUE) under different rates
