Active nuclease inhibition over passive freezing secures the genomic archive of fish eye lenses

Abstract Fish eye lenses offer a chronological archive of individual life histories and preserve genomic DNA. However, integrating ecological and genetic data is hindered by post‐mortem nuclease degradation, and standardized DNA preservation protocols for this tissue remain undef...

Artificial intelligence in human parasitic gastrointestinal infections: a systematic review closing the protozoan gap

Abstract Human parasitic gastrointestinal infections affect over 3.5 billion people worldwide, yet their diagnostic management remains heavily dependent on conventional microscopy. While artificial intelligence (AI) has emerged as a valuable tool in digital parasitology, its appl...

Dynamics of coupled nonlinear diffusion–reaction systems

We study two coupled nonlinear Fisher–Kolmogorov equations with anomalous diffusion. Because analytical solutions are difficult to obtain, we use a reduced collective-coordinate method based on two time-dependent power-law assumptions. This approach reduces the original partial d...

Redescription and First Molecular Characterization of Lernanthropus caudatus Wilson, 1922 (Copepoda: Lernanthropidae): A Comparative Integrative Analysis

The aim of this study was to redescribe and provide the first molecular characterization of the copepod Lernanthropus caudatus Wilson, 1922 (Copepoda: Lernanthropidae) collected from three sparids ( Archosargus probatocephalus , A. rhomboidalis , and Lagodon rhomboides ) from the...

Scale Mixture of Akash Distribution with Applications to Income Data

In this paper, the scale mixture of Akash (SMAK) distribution is introduced. This new distribution results from a scale mixture of the Akash distribution and the exponential distribution. The SMAK distribution is an alternative to two-parameter distributions with a heavy right ta...

Future of lithium industry in Chile and the national lithium strategy: integration of solar evaporation, direct lithium extraction, and controlled reinjection

The lithium industry in Chile is undergoing a critical transition from an extensive evaporitic model to a more efficient, sustainable, and technologically integrated operation. This paper analyzes the main challenges of the Salar de Atacama, considering its high lithium concentra...

Hybrid Cloud Segmentation Approach Combining YOLOv8 Instance Segmentation with HSV Thresholding for Multi-Site Assessment

Accurate cloud segmentation from ground-based fisheye camera imagery is essential for solar irradiance forecasting and photovoltaic system optimization. Traditional computer vision approaches, such as HSV thresholding and K-means clustering, face significant limitations when appl...

Vulnerable microbial communities in Atacama-Altiplano wetlands: modern analogs of ancient ecosystems with implications for sustainability and conservation

Abstract The Altiplano-Puna plateau lies at ∼4,000 m above sea level in the volcanic Andes cordillera. Together with the adjacent Atacama Desert, it forms one of the most hyperarid regions on the planet. Wetlands are rare, influenced by hydrothermalism and, due to high evaporatio...

Mitogenome-Informed Metabarcoding for Non-Invasive Identification of Sympatric Flamingos in Northern Chile

The Chilean flamingo (Phoenicopterus chilensis) is a widely distributed South American species inhabiting diverse wetland ecosystems from Ecuador and Peru south to Chile and Argentina, and east to Brazil, Uruguay, and Paraguay, ranging from sea level to high-altitude Andean salar...
