Numerical modelling of glacial lake outburst floods using physically based dam-breach models [PDF]

, 2015
The instability of moraine-dammed proglacial lakes creates the potential for catastrophic glacial lake outburst floods (GLOFs) in high-mountain regions.

Effects of Straw Incorporation and Tillage Depth on Soil Quality in Mollisol Profiles

Land Degradation &Development, EarlyView.
ABSTRACT Although improvements in soil quality under straw incorporation have been well documented, responses across soil profiles under different tillage depths remain unclear. To address this issue, a field experiment was established in 2011 in Mollisols with conventional tillage (20 cm depth) without straw (CT) and with straw (SCT), no tillage with ...

Mixed Litter Decomposition Drives Functional Gene Rearrangement in the Microbial Carbon Cycle

Land Degradation &Development, EarlyView.
ABSTRACT Understanding how mixed‐species litter decomposition regulates microbial communities and carbon cycling is vital for guiding ecosystem restoration and climate change mitigation, as it is a key process for nutrient cycling and carbon sequestration. A 15‐month field experiment compared single‐species (Pinus sylvestris var.

Skaftafellsjökull, Iceland: glacial geomorphology recording glacier recession since the Little Ice Age

, 2017
A 1:5700 scale map of the recently deglaciated foreland of Skaftafellsjökull, Iceland as it appeared in 2007, depicts a typical active temperate glacial landsystem with a clear pattern of sequentially changing push moraine morphologies, including ...

Revealing Dust Source Changes in East Asia From Past to Future: An Interpretable Deep Learning Approach

Land Degradation &Development, EarlyView.
ABSTRACT Aeolian dust source areas are controlled by climate and human activities and are closely associated with land degradation, yet their long‐term evolution under global warming remains insufficiently quantified. An integrated framework that couples a U‐Net segmentation model with Shapley Additive Explanations (SHAP) was built to map and attribute

Optimized Fertilization Balances Microbial Carbon and Nitrogen Use Efficiency: Evidence From Microbial Communities

Land Degradation &Development, EarlyView.
ABSTRACT Optimized fertilization involving reduced mineral N input and organic substitution can alter resource stoichiometry, microbial carbon use efficiency (CUE) and nitrogen use efficiency (NUE). However, how fertilization‐induced resource imbalance reshapes microbial community to regulate CUE and NUE remains unclear. We conducted a field experiment

Investigating Holocene mountain glaciations: a plea for the supremacy of glacial geomorphology when reconstructing glacier chronologies

Erdkunde, 2018
Investigating Holocene glacier chronologies constitutes a valuable approach within palaeoclimatic research. Recent progress of numerical dating techniques, in particular terrestrial cosmogenic nuclide dating (TCND), has given it new momentum.

Post‐Fire Soil Organic Carbon Dynamics: Decline and Recovery Over Two Decades

Land Degradation &Development, EarlyView.
ABSTRACT Wildfire can significantly alter soil organic carbon (SOC) dynamics in forest ecosystems, with complex temporal patterns following fire events. However, research on post‐fire SOC recovery remains limited, particularly in dry‐warm valley regions that are prone to frequent forest fires.

Glacial geomorphology of the Marinelli and Pigafetta glaciers, Cordillera Darwin Icefield, southernmost Chile

, 2018
This paper presents a glacial geomorphological map relating to two rapidly receding glaciers in the Cordillera Darwin Icefield. The Marinelli marine-terminating glacier and Pigafetta freshwater-terminating glacier are selected to represent different ...
