Moderate Biochar–Compost Mixture Is More Effective in Improving Biomass, Nutrient Fluxes, and Photosynthetic Outputs for Sustainable Land Restoration and Soil Fertility

Land Degradation &Development, EarlyView.
ABSTRACT Soil nutrient depletion severely constrains crop productivity in degraded and saline environments. Strategies such as biochar–compost integration could be useful for sustainable agriculture and land restoration on a global scale. This study evaluated the effects of biochar (1% Bc), compost (1% Co), and their blends (0.5% Bc + 0.5% Co and 1% Bc

Carbon–Phosphorus Limitation Is Associated With Shifts in Microbial Life‐History Strategies Across Vegetation Restoration Modes in Alpine Sandy Land on the Tibetan Plateau

Land Degradation &Development, EarlyView.
ABSTRACT Alpine sandy land on the Tibetan Plateau is fragile, with poorly developed soils, low nutrient availability, and weak biological resilience. Vegetation restoration is widely used to improve soil functioning, yet how microbial nutrient limitation and life‐history strategies vary among restoration modes remains unclear.

An Anisotropic Constitutive Model for Crushable Geomaterials Based on Non‐Stationary Critical State Line Concept

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT In this paper, the dependencies of granular soil behaviour on particle crushing and fabric anisotropy are formulated within a novel model based on bounding surface plasticity theory enriched by the non‐stationary critical state line (NCSL) concept.

Rearrangement Towards Stability: Plastic Shakedown in Granular Materials Under Thermal Cycles

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Granular materials are routinely subjected to thermal cycling due to natural and anthropogenic phenomena. Despite the ubiquity of this occurrence and its relevance for science, engineering, and technology, the long‐term thermo‐mechanical response of granular materials to repeated heating and cooling remains poorly understood.

Historical data reveal earlier flowering under environmental change

Nordic Journal of Botany, EarlyView.
Global temperatures have risen ~ 1.1°C since the 1800s and the mean annual air temperature in the Arctic has increased by nearly four times the global average. Temperature has a significant effect on fundamental life‐cycle events of flora and fauna. With temperatures increasing, Arctic plants are expected to shift their active periods accordingly, with

Elevation‐dependent soil and plant responses to a decade of warming and species removal

Oikos, EarlyView.
Understanding how ecosystems retain or release carbon under warming is a critical challenge. Dominant plant species, which contribute the most biomass, can mediate ecosystem responses to warming by modifying microclimate and nutrient cycling. To investigate how warming and shifts in plant dominance interact to affect carbon and nutrient dynamics, we ...

Mechanisms and impacts of future plant invasions: research agendas and management needs under disruptive social‐ecological change scenarios

Oikos, EarlyView.
No‐analogue futures are characteristic of the Anthropocene, but how global change, and societies' responses, will affect plant invasions remains unclear. Conducting research now to address future needs is crucial for guiding invasion management and policy.
