AI Article Synopsis
Article Abstract
Focusing on literature published in 2018-2020, we review inferences about: (i) how ancient DNA is contributing to clarify the peopling of the Americas and the dispersal of its first inhabitants, (ii) how the interplay between environmental diversity and culture has influenced the genetic structure and adaptation of Andean and Amazon populations, (iii) how genetics has contributed to our understanding of the Pre-Columbian Tupi expansion in Eastern South America, (iv) the subcontinental origins and dynamics of Post-Columbian admixture in the Americas, and finally, (v) episodes of adaptive natural selection in the American continent, particularly in the high altitudes of the Andes.

Seascape Genomics of Red Abalone: Limited Range-Wide Population Structure and Evidence for Local Adaptation.
Mol Ecol
January 2025
Department of Environmental Toxicology, University of California Davis, Davis, California, USA.
Characterising patterns of genetic diversity including evidence of local adaptation is relevant for predicting and managing species recovering from overexploitation in the face of climate change. Red abalone (Haliotis rufescens) is a species of conservation concern due to recent declines from overharvesting, disease and climate change, resulting in the closure of commercial and recreational fisheries. Using whole-genome resequencing data from 23 populations spanning their entire range (southern Oregon, USA, to Baja California, MEX) we investigated patterns of population connectivity and genotype-environment associations that would reveal local adaptation across the mosaic of coastal environments that define the California Current System (CCS).

Department of Forest and Wildlife Ecology, University of Wisconsin-Madison, Madison, Wisconsin, USA.
Fire shapes biodiversity in many forested ecosystems, but historical management practices and anthropogenic climate change have led to larger, more severe fires that threaten many animal species where such disturbances do not occur naturally. As predators, owls can play important ecological roles in biological communities, but how changing fire regimes affect individual species and species assemblages is largely unknown. Here, we examined the impact of fire severity, history, and configuration over the past 35 years on an assemblage of six forest owl species in the Sierra Nevada, California, using ecosystem-scale passive acoustic monitoring.

Dipartimento di Architettura, University of Naples Federico II, Naples, Italy.
A key challenge in the art and archaeological field is the instrumental analysis of objects and materials while preserving their integrity. In this study, the world-renowned artwork Alexander Mosaic (The Issus Battle, collection of the National Archaeological Museum of Naples, IT), the most iconic representation of the face of the Macedonian king Alexander the Great coming from a Pompeii domus, was thoroughly analyzed with mobile and non-invasive methods, within a great project of restoration started in 2020. Representative areas of the Mosaic, overall consisting of ca.

Department of Obstetrics and Gynecology, the Affiliated Hospital of Nantong University, Nantong, Jiangsu 226001, China.
Objective: To explore the genetic characteristics of a Chinese pedigree with rare mosaic 11q partial duplication and its pathogenetic mechanisms.
Methods: A pedigree which underwent prenatal diagnosis at Wenzhou Central Hospital between September 25, 2015 and November 30, 2023 was selected for the study. Clinical data were collected from the pedigree.

Department of Endocrinology and Internal Medicine, Aarhus University Hospital, Palle-Juul Jensens Boulevard 165, 8200 Aarhus N, Denmark.
Context: Few studies have reported on males with 45,X/46,XY mosaicism. Most studies stem from pediatric settings and knowledge of natural history and long-term health outcomes are therefore lacking.
Objective: To describe long-term health outcomes in males with 45,X/46,XY in comparison to the general population.
