ABSTRACT Climate change is inducing wide-scale permafrost thaw in the Arctic and subarctic, triggering concerns that long-dormant pathogens could reemerge from thawing ground initiate epidemics or pandemics. Viruses, as opposed to bacterial pathogens, garner particular interest because outbreaks cannot be controlled with antibiotics, though effects can mitigated by vaccines newer antiviral drugs. To evaluate potential hazards posed viral emerging permafrost, we review information a diverse range of disciplines. This includes efforts recover infectious virus human remains, studies on disease occurrence polar animal populations, investigations into persistence infectivity assessments exposure enormous diversity present environment. Based currently available knowledge, conclude risk viruses no greater than other environments such temperate soils aquatic systems.

Unraveling the diversity and cultural heritage of fruit crops through paleogenomics

Trends in Genetics, Год журнала: 2024, Номер 40(5), С. 398 - 409

Опубликована: Фев. 28, 2024

Abundant and plentiful fruit crops are threatened by the loss of diverse legacy cultivars which being replaced a limited set high-yielding ones. This article delves into potential paleogenomics that utilizes ancient DNA analysis to revive lost diversity. By focusing on grapevines, date palms, tomatoes, recent studies showcase effectiveness paleogenomic techniques in identifying understanding genetic traits crucial for crop resilience, disease resistance, nutritional value. The approach not only tracks landrace dispersal introgression but also sheds light domestication events. In face major future environmental challenges, integrating with modern breeding strategies emerges as promising avenue significantly bolster sustainability.

Museomics and morphological analyses of historical and contemporary peninsular Italian wolf (Canis lupus italicus) samples

Scientific Reports, Год журнала: 2025, Номер 15(1)

Abstract After centuries of decline and protracted bottlenecks, the peninsular Italian wolf population has naturally recovered. However, an exhaustive comprehension effects such a conservation success is still limited by reduced availability historical data. Therefore, in this study, we morphologically genetically analyzed contemporary samples, also exploiting optimization innovative bone DNA extraction method, to describe morphological variability subspecies its genetic diversity during last 30 years. We obtained high amplification genotyping rates for tissue, blood petrous samples. Multivariate, clustering analyses confirmed that Apennine well-distinguishable from both European wolves dogs, with no natural immigration other populations, while remained low across three decades, without significant changes between specimens. This study highlights scientific value well-maintained museum collections, demonstrates bones represent reliable sources, emphasizes need long-term monitor dynamics peculiar populations ensure appropriate management actions.

A High‐Throughput Ancient DNA Extraction Method for Large‐Scale Sample Screening

Molecular Ecology Resources, Год журнала: 2025, Номер unknown

Опубликована: Фев. 6, 2025

ABSTRACT Large‐scale DNA screening of palaeontological and archaeological collections remains a limiting costly factor for ancient studies. Several extraction protocols are routinely used in laboratories have even been automated on robotic platforms. Robots offer solution high‐throughput but the costs, as well necessity trained technicians engineers, can be prohibitive some laboratories. Here, we present alternative to robot‐based using 96‐column plate. When compared routine single MinElute columns, retrieved highly similar endogenous contents, an important metric screening. Mitogenomes with coverage depth greater than 0.1× could generated allowed taxonomic assignment. However, average fragment lengths, damage library complexities significantly differed between methods these differences became nonsignificant after modification our purification protocol. Our method allows generation 96 extracts within approximately 4 hours laboratory work while bringing cost down by ~39% columns. Additionally, formally demonstrate that addition Tween‐20 during elution step results higher complexity libraries, thereby enabling genome same sequencing effort.

Navigating Past Oceans: Comparing Metabarcoding and Metagenomics of Marine Ancient Sediment Environmental DNA

Molecular Ecology Resources, Год журнала: 2025, Номер unknown

Опубликована: Фев. 20, 2025

ABSTRACT The condition of ancient marine ecosystems provides context for contemporary biodiversity changes in human‐impacted oceans. Sequencing sedimentary DNA (sedaDNA) is an emerging method generating high‐resolution time‐series data, offering insights into past ecosystems. However, few studies directly compare the two predominant sedaDNA sequencing approaches: metabarcoding and shotgun‐metagenomics, it remains unclear if these methodological differences affect diversity metrics. We compared methods using from archived sediment record sampled Skagerrak, North Sea, spanning almost 8000 years. performed a eukaryotic 18S rRNA region (V9) sequenced 153–229 million metagenomic reads per sample. Our results show limited overlap between metagenomics, with only three metazoan genera detected by both methods. For overlapping taxa, detections became inconsistent samples older than 2000 years, while metagenomics taxa throughout time series. observed divergent patterns alpha diversity, indicating decreased richness towards present showing increase. beta were similar methods, discrepancies data comparisons. findings demonstrate that choice significantly impacts record. While we stress variation degradation among may not be strongly affected, researchers should exonerate explanations cores, particularly when considering before making ecological interpretations.

Abstract The spatial distribution of individuals within ecological assemblages and their associated traits behaviors are key determinants ecosystem structure function. Consequently, determining the species, how distributions influence patterns species richness across ecosystems today in past, helps us understand what factors act as fundamental controls on biodiversity. Here, we explore niche modeling has contributed to understanding spatiotemporal past biodiversity evolutionary processes. We first perform a semiquantitative literature review capture studies that applied models (ENMs) identifying 668 studies. coded each study according focal taxonomic group, whether used fossil evidence, it relied evidence or methods addition ENMs, scale study, temporal intervals included ENMs. trends publication categories anchor discussion recent technical advances modeling, focusing paleobiogeographic ENM applications. then explored contributions ENMs paleobiogeography, with particular focus examining drivers range dynamics; phylogeography within-lineage macroevolutionary processes, including change, speciation, extinction; community assembly; conservation paleobiogeography. Overall, powerful tools for elucidating patterns. most commonly Quaternary dynamics, but an increasing number use gain important insight into both processes pre-Quaternary times. Deeper integration phylogenies may further extend those insights.
