Divergent Functional Roles of Shredder Size: Interspecific Versus Intraspecific Effects on Aquatic Leaf Litter Decomposition

Ecology and Evolution, Volume 16, Issue 1, January 2026.
Biodiversity enhances stream ecosystem efficiency, with greater taxonomic and trait diversity improving functions like decomposition. Shredder diversity arises from both species differences and ontogenetic variation. We experimentally examined these factors to reveal how they shape the magnitude and timing of organic matter processing in streams ...

High Habitat Potential but Limited Connectivity for Brown Bears Throughout Europe

Diversity and Distributions, Volume 32, Issue 1, January 2026.
ABSTRACT Aim Large carnivores worldwide have experienced substantial range contractions due to human activities, though several species are recolonising parts of their historical range. We aimed to assess current and potential European brown bear (Ursus arctos arctos) habitat as well as habitat connectivity on a continental scale. Location The extended

Conditions for Accretion Favoring an Unmelted Callisto and a Differentiated Ganymede

The Planetary Science Journal
Analysis of Callisto’s moments of inertia, derived from Galileo’s gravity data, suggests that its structure is not fully differentiated. This possibly undifferentiated state contrasts sharply with the globally molten state inferred in its counterpart ...

Complexity and Heterogeneity in Cryptocurrency Prices: An Analysis Based on Gaussian Mixture Model and Consensus Clustering

Intelligent Systems in Accounting, Finance and Management, Volume 32, Issue 4, December 2025.
ABSTRACT This study investigates the daily price patterns and behavioral similarities among cryptocurrencies, focusing on two key research questions: (1) Do cryptocurrency prices vary consistently throughout the day? (2) Can cryptocurrencies be meaningfully grouped based on their behavioral patterns? Using Gaussian mixture models (GMMs), we analyze the

Reduced Shear Modulus and Altered Lamellar Morphology of the Outer Annulus Fibrosus in Painful Intervertebral Disc Degeneration Compared With Tissue From Non‐Surgical Controls

JOR SPINE, Volume 8, Issue 4, December 2025.
Disc degeneration (DD) results in a mechanically dysfunctional disc through progressive loss of the intervertebral disc's (IVD) highly organized structure. This study measured shear and structure properties of the outer annulus fibrosus in surgical DD and minimally degenerative (non‐DD) donor individuals.

Ammonites and magnetostratigraphy of the Berriasian–Valanginian boundary deposits from eastern Crimea

Geologica Carpathica, 2017
Euthymi, Crassicostatum and Callisto ammonite subzones, correlable with Paramimounum, Picteti, and Alpillensis subzones and probably with the Late Berriasian Otopeta Subzone of the Boissieri Standard Zone have been recognized in calcareous clays of the ...

Radar Polarimetry in Glaciology: Theory, Measurement Techniques, and Scientific Applications for Investigating the Anisotropy of Ice Masses

Reviews of Geophysics, Volume 63, Issue 4, December 2025.
Abstract Dielectric anisotropy in ice alters the propagation of polarized radio waves, so polarimetric radar sounding can be used to survey anisotropic properties of ice masses. Ice anisotropy is either intrinsic, associated with ice‐crystal orientation fabric (COF), or extrinsic, associated with material heterogeneity, such as bubbles, fractures, and ...
