A 14th century CE Brucella melitensis genome and the recent expansion of the Western Mediterranean clade.

Brucellosis is a disease caused by the bacterium Brucella and typically transmitted through contact with infected ruminants. It is one of the most common chronic zoonotic diseases and of particular interest to public health agencies. Despite its well-known transmission history and characteristic symptoms, we lack a more complete understanding of the evolutionary history of its best-known species-Brucella melitensis.

Potential Factors Conditioning the Compliance to Mandatory Face Covering in the Public Space Due to SARS-CoV-2 Pandemic.

Background: During the SARS-CoV-2 pandemic, we could observe different attitudes towards restrictive bans and orders.

Aim: The research aimed to examine the potential psychological factors, such as generalized anxiety, fear of COVID-19 or social approval, related to the approach to mandatory face covering in public spaces.

Methods: The web-assisted interviews survey was used among 202 participants, which included socio-demographical data, approach to face covering, the Generalized Anxiety Disorder Scale, the COVID-19 Anxiety Scale, and The Questionnaire of Social Approval.

Impact of Personal Experience of COVID-19 Disease on Recreational Anglers' Attitudes and Behaviors.

Background: Anglers are a large social group with access to a "relatively safe" form of recreation, that allows the opportunity to relieve stress. An important question, however, is how they did so, and to what extent their perceived COVID-19 transition status influenced decisions both in life and at the fishing site.

Aim: Our study aimed to determine the dynamics of anglers' attitudes and behaviors during the COVID-19 pandemic as a result of the different statuses of their exposure to the SARS-CoV-2 virus.

Examining pathogen DNA recovery across the remains of a 14th century Italian friar (Blessed Sante) infected with Brucella melitensis.

Objective: To investigate variation in ancient DNA recovery of Brucella melitensis, the causative agent of brucellosis, from multiple tissues belonging to one individual MATERIALS: 14 samples were analyzed from the mummified remains of the Blessed Sante, a 14 century Franciscan friar from central Italy, with macroscopic diagnosis of probable brucellosis.

Methods: Shotgun sequencing data from was examined to determine the presence of Brucella DNA.

Results: Three of the 14 samples contained authentic ancient DNA, identified as belonging to B.

The Significance of Angling in Stress Reduction during the COVID-19 Pandemic-Environmental and Socio-Economic Implications.

Recreational fishing and other outdoor recreational activities have been proven to have positive effects on mental health, including neutralizing pandemic stress. This study aims to identify the perceptions and behavior of recreational anglers during the COVID-19 pandemic along with identifying the factors that determine attitudes. This study is essential for understanding the complex economic, social, and environmental implications associated with a pandemic.

Pleistocene mitogenomes reconstructed from the environmental DNA of permafrost sediments.

Traditionally, paleontologists have relied on the morphological features of bones and teeth to reconstruct the evolutionary relationships of extinct animals. In recent decades, the analysis of ancient DNA recovered from macrofossils has provided a powerful means to evaluate these hypotheses and develop novel phylogenetic models. Although a great deal of life history data can be extracted from bones, their scarcity and associated biases limit their information potential.

Collapse of the mammoth-steppe in central Yukon as revealed by ancient environmental DNA.

The temporal and spatial coarseness of megafaunal fossil records complicates attempts to to disentangle the relative impacts of climate change, ecosystem restructuring, and human activities associated with the Late Quaternary extinctions. Advances in the extraction and identification of ancient DNA that was shed into the environment and preserved for millennia in sediment now provides a way to augment discontinuous palaeontological assemblages. Here, we present a 30,000-year sedimentary ancient DNA (sedaDNA) record derived from loessal permafrost silts in the Klondike region of Yukon, Canada.

American mastodon mitochondrial genomes suggest multiple dispersal events in response to Pleistocene climate oscillations.

Pleistocene glacial-interglacial cycles are correlated with dramatic temperature oscillations. Examining how species responded to these natural fluctuations can provide valuable insights into the impacts of present-day anthropogenic climate change. Here we present a phylogeographic study of the extinct American mastodon (Mammut americanum), based on 35 complete mitochondrial genomes.

New insight into the motivations of anglers and fish release practices in view of the invasiveness of angling.

The popularity of angling on a global scale reflects the individual needs of people from different social groups in many countries. The socio-economic background and intensity of needs are variable over time and can be modified. These arguments support the development and need to update research among anglers.

A comprehensive genomic history of extinct and living elephants.

Elephantids are the world's most iconic megafaunal family, yet there is no comprehensive genomic assessment of their relationships. We report a total of 14 genomes, including 2 from the American mastodon, which is an extinct elephantid relative, and 12 spanning all three extant and three extinct elephantid species including an ∼120,000-y-old straight-tusked elephant, a Columbian mammoth, and woolly mammoths. Earlier genetic studies modeled elephantid evolution via simple bifurcating trees, but here we show that interspecies hybridization has been a recurrent feature of elephantid evolution.
