Evidence of Rapid Phenocryst Growth of Olivine During Ascent in Basalts From the Big Pine Volcanic Field: Application of Olivine‐Melt Thermometry and Hygrometry at the Liquidus

Geochemistry, Geophysics, Geosystems, 2020
The Quaternary Big Pine (BP) volcanic field in eastern California is notable for the occurrence of mantle xenoliths in several flows. This points to rapid ascent of basalt through the crust and precludes prolonged storage in a crustal reservoir.

Investigating of Susceptibility of Maharloo Lake Sediments to Wind Erosion and Determination of Dust Movement Direction [PDF]

مدیریت بیابان, 2019
Wind erosion is one of the most important natural processes in arid and semi-arid regions. In recent years, due to lake drying, dust producing has been increased from lakes and wetlands surfaces.

Deep Origin and Shallow Launch for the Etna 122 B.C. Mafic Plinian Eruption

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Basaltic Plinian eruptions challenge our understanding of explosive volcanism. The 122 B.C. Plinian eruption of Etna ranks among the most powerful mafic explosive events known. Here, we combine volatile barometry of 122 B.C. from olivine‐hosted melt and fluid inclusions with comparative data from the sub‐Plinian Fall Stratified eruption at ...

Identifying Distinct Pre‐Eruptive Composition‐H2O‐Time Trends Using Plagioclase

Geochemistry, Geophysics, Geosystems
Macrocrysts (large crystals) in magmas offer a premier record of pre‐eruptive magma storage conditions encoded in their chemistry and texture. Careful study of macrocryst zoning can deconvolve the conditions of crystal growth and the relative time a ...

Skin Resistance to Dehydration: A Theory‐Informed Trait Gradient in Anurans

Global Ecology and Biogeography, Volume 35, Issue 6, June 2026.
ABSTRACT Aim Anurans' sensitivity to hydric stress has driven adaptive changes in multiple traits, potentially displaying geographical clines, as is the case with body size. A longstanding body of research suggests that skin resistance to water loss may also vary geographically in response to water loss.

Does water vole diet meet the prerequisites of the “plant hypothesis” for explaining population cycles?

Ecosphere, Volume 17, Issue 5, May 2026.
Abstract Rodent population cycles are observed in highly seasonal environments. As most rodents are herbivorous, the availability and the quality of their food resources vary greatly across seasons. Furthermore, it is well documented that herbivore densities have a measurable effect on vegetation and, conversely, that vegetation dynamics can influence ...

Plagioclase‐Saturated Melt Hygrothermobarometry and Plagioclase‐Melt Equilibria Using Machine Learning

Geochemistry, Geophysics, Geosystems
Compositions of plagioclase‐melt pairs are commonly used to constrain temperatures (T), dissolved water contents (H2O) and pressures (P) of pre‐eruptive magma storage and transport.

Combined effect of moisture and electrostatic charges on powder flow

EPJ Web of Conferences, 2017
It is well known in industrial applications involving powders and granular materials that the relative air humidity and the presence of electrostatic charges influence drastically the material flowing properties.

Welfare assessment of turkeys (Meleagris gallopavo gallopavo) on farm

EFSA Journal, Volume 24, Issue 2, February 2026.
Abstract This Scientific Opinion assesses the welfare of turkeys of all ages (Meleagris gallopavo gallopavo) on farm in relation to the type and condition of the litter, type and availability of enrichment (including covered veranda and outdoor range), space allowance, concentrations of ammonia and carbon dioxide, effective environmental temperature ...
