Body Size Regulates Niche Overlap Asymmetry in the Subtropical Andes Rain Shadow: Isotopic Paleoecology of Oligocene South American Ungulates

Integrative Zoology, EarlyView.
This study provides the first isotopic analysis of Oligocene mammals from Quebrada Fiera, Mendoza, Argentina, filling a major gap in South American paleontology. It reveals a latitudinal gradient in aridity due to the Andean rain shadow and highlights the role of (semi)permanent water bodies in sustaining diverse herbivore communities. Additionally, it

Edge detection in Cassini astronomy image using Extreme Learning Machine

MATEC Web of Conferences, 2018
Edge detection is often performed on disc-like object in Cassini astronomy images to accurately obtain the object’s center position. The existing edge extraction methods usually produce lots of false edge pixels because of noise and the interior details ...

European Network for Optimization of Veterinary Antimicrobial Therapy (ENOVAT) 2025 guidelines for surgical antimicrobial prophylaxis in dogs and cats

Journal of Small Animal Practice, EarlyView.
Surgical antimicrobial prophylaxis involves the administration of antimicrobials to reduce the risk of a surgical site infection and represents a significant proportion of all antimicrobial use in cats and dogs. This evidence‐based, European Network for Optimization of Veterinary Antimicrobial Therapy guideline provides recommendations for both peri ...

Radio Pulse Power Distribution of Lightning in Jupiter's 2021–2022 Stealth Superstorms

AGU Advances, Volume 7, Issue 2, April 2026.
Abstract Surveys and observations of lightning on Jupiter prior to the NASA Juno mission used night‐side imaging approaches, and a common conclusion was that the optical energy was similar to the highest energy terrestrial lightning flashes, or superbolts.

Local Time Asymmetry in Energetic Electron Distribution Within Saturn's Inner Magnetosphere

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Electrons of several hundred keV in Saturn's ring current are important seed components of the radiation belt. In this study, we have statistically analyzed the spatial distribution of energetic electrons on the equatorial plane of the inner magnetosphere based on the Cassini in situ observations.

New Constraints on the Calabrian Arc (Central Mediterranean) Geodynamics: High‐Resolution Imaging of Lithospheric and Upper Mantle Discontinuities From P and S Receiver Functions

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract The Calabrian Arc subduction system (Central Mediterranean) is characterized by a deep and narrow (200 km) slab. Addressing the poorly understood link between shallow and deep mantle structures, we present the first high‐resolution mapping of crustal and upper mantle discontinuities across the Calabrian Arc and Southern Tyrrhenian basin.

Realismo epistemológico, referencia y verosimilitud

Crítica, 2018
This paper attempts to determine the commitements of the realist view of scientific theories. First, it distinguishes between ontological realism and epistemological realismo Then, it affirms that the latter is committed with the concepts of reference ...

Unveiling Diet Preferences and Their Nutritional Drivers Through Metabarcoding: The Case of Alpine Marmot (Marmota marmota L.) in High Altitude Grazed Pastures

Ecology and Evolution, Volume 16, Issue 3, March 2026.
The alpine marmot (Marmota marmota), a crucial component of alpine ecosystems, serves both as a key player in the food chain and as an ‘ecosystem engineer.’ Employing DNA metabarcoding of fecal samples, this study investigated the diet composition and foraging strategies of four alpine marmot colonies across diverse alpine pasture ecosystems throughout
