Drought resistance is influenced by soil water uptake depth in dryland shrubs

Plant Biology, EarlyView.
Higher drought resistance was associated with shifts from shallow to deep soil water uptake under drier conditions, with both covarying with functional traits in drylands. Abstract Climate change exacerbates aridity in dry shrublands leading to different responses of coexisting shrubs to drought, including different resistance (capacity to sustain ...

Early development of anoxia prior to the main euxinic phase of the Jenkyns Event on the margin of the Western Tethys (Sachrang Basin, Eastern Alps)

Sedimentology, EarlyView.
ABSTRACT Although the global expansion of oxygen‐depleted marine environments during the Early Toarcian Jenkyns Event (or Toarcian Oceanic Anoxic Event) is primarily inferred from successions in the NW European epicontinental basins, the timing of the expansion of anoxia in Tethyan basins, where hydrography potentially played a minor role, is poorly ...

A chemical model of meteoric ablation [PDF]

Atmospheric Chemistry and Physics, 2008
Most of the extraterrestrial dust entering the Earth's atmosphere ablates to produce metal vapours, which have significant effects on the aeronomy of the upper mesosphere and lower thermosphere.

NASA Meteoroid Engineering Model (MEM) Version 3 [PDF]

, 2020
The Meteoroid Engineering Model (MEM) version 3 is NASAs most current and accurate model of the meteoroid environment. MEM 3 supersedes all previous versions of MEM, including MEM Release 2.0 (MEMR2), MEM Release 1.0c (MEMR1c), and previously internally ...

Conditions and timing for the precipitation of early marine diagenetic dolomite in the Triassic Dolomia Principale (northern Italy)

Sedimentology, EarlyView.
ABSTRACT Thermodynamic constraints and empirical evidence often suggest that fabric‐retentive replacement dolomites are stable carbonate minerals that preserve ancient seawater properties. This study evaluates this hypothesis by examining the Upper Triassic Dolomia Principale in Northern Italy.

Fault‐Controlled Permeability: A Key Parameter in Geothermal Electricity Production Assessment

Terra Nova, EarlyView.
ABSTRACT Geothermal energy is central to the global green energy transition, but its development has long focused on regions with positive thermal anomalies. Through a semi‐quantitative global‐scale review and spatial analysis of 361 geothermal sites, we show that 56.2% of global geothermal electricity production occurs in regions with thermal ...
