Scientists’ warning on the global destruction of rock outcrop ecosystems

Conservation Biology, EarlyView.
Abstract Rock outcrops are geological formations that harbor a highly specialized biota adapted to harsh environmental conditions that differ from their surrounding landscapes. They are globally distributed, especially in old, highly weathered landscapes, and can function as habitat islands containing high levels of endemism and distinct evolutionary ...

Effect of Different Parameters on Charpy Impact Properties of Quasi-Isotropic Epoxy Composites Reinforced with Basalt and Glass Fibers

Journal of Advanced Materials in Engineering, 2015
In this study, the effects of different parameters on charpy impact properties of pure and hybrid composite laminates reinforced with basalt and glass filaments were investigated.

Influence of Laser Repetition Rate, Fluence and Spot Size on LA‐Q‐ICP‐MS/MS 87Sr/86Sr Precision: Insights from Apatites and Silicate Glasses

Geostandards and Geoanalytical Research, EarlyView.
Key Points Higher laser repetition rate, fluence and larger spot size increase signal intensity. Higher laser repetition rate produces overlaps in aerosolised particles, improving signal stability and precision. For Sr‐rich materials, moderate spot diameter (≤ 60 μm), 3 J cm‐2 fluence and ≥ 12 Hz repetition rate are recommended.

(Ultra)high‐Pressure Metamorphism in Sedimentary Versus Basaltic Rocks: Insights From a Variscan Mélange in the South Carpathians

Journal of Metamorphic Geology, EarlyView.
ABSTRACT Reconstructing the pressure–temperature–time (P–T–t) evolution of (ultra)high‐pressure rocks is essential for constraining subduction and collisional dynamics. Subduction zones are often investigated using basic eclogites, whereas nonbasic high‐pressure rocks remain comparatively understudied, potentially hindering a comprehensive ...

California's vernal‐pool mousetails (Myosurus, Ranunculaceae): Phylogenetic analysis of ddRADseq data, hybridization tests, and species delimitation

Journal of Systematics and Evolution, EarlyView.
We present the first phylogenetic analysis of the Californian species of Myosurus. Our ddRADseq analysis reveals considerably more diversity than what was recognized in recent floristic treatments. Myosurus minimus subsp. apus was found to be a rare species restricted to Southern California and northwestern Baja California.

Studies of Basalt Through Laser Induced Breakdown Spectroscopy (LIBS) for the Manufacturing of Lapilli Blocks

Minería y Geología, 2016
Basaltic samples selected from different areas of Tenerife were analyzed by applying laser induced breakdown spectroscopy (LIBS), Raman spectroscopy and X Ray Diffraction (XRD) in order to identify the basic chemical composition and mineralogy. The basic

Exploring the Association Between Complaints of Sensory Hypersensitivity and Sleep Disturbances After Acquired Brain Injury: A Cross‐Sectional Study

Journal of Sleep Research, EarlyView.
ABSTRACT Sleep disturbances are prevalent after acquired brain injury and negatively affect quality of life. Sensory hypersensitivity may cause or exacerbate sleep disturbances, yet evidence on this relationship after acquired brain injury is lacking. The aim of this study was to investigate the hypothesised positive relationship between the severity ...

LifeMet: Report on the 2024–2025 meteorite recovery expedition in Dronning Maud Land, Antarctica for the study of microbe–meteorite interactions

Meteoritics &Planetary Science, EarlyView.
Abstract Since the discovery of nine meteorites near the Yamato mountains in 1969, Antarctica has been recognized as a superb location for meteorite recovery. While Antarctic recovery expeditions prioritize meteorite preservation for mineralogical and planetary studies, meteorites are not typically collected for biological applications.
