Psychological and social factors associated with mental health of European dual career athletes: A systematic review.

Dual careers (DCs) are challenging trajectories followed by athletes willing to develop their academic/professional career with their athletic careers. These trajectories usually entail additional stressors, which can decrease athletes' mental health or even increase their risk of mental ill-health. While existing research has recognized the importance of psychological and social factors in both of these areas separately, we lack systematic knowledge on which factors are associated with European DC athlete mental health outcomes, making evidence-based practice more challenging.

Counting Cherry Reduction Sequences in Phylogenetic Tree-Child Networks is Counting Linear Extensions.

Orchard and tree-child networks share an important property with phylogenetic trees: they can be completely reduced to a single node by iteratively deleting cherries and reticulated cherries. As it is the case with phylogenetic trees, the number of ways in which this can be done gives information about the topology of the network. Here, we show that the problem of computing this number in tree-child networks is akin to that of finding the number of linear extensions of the poset induced by each network, and give an algorithm based on this reduction whose complexity is bounded in terms of the level of the network.

How is coaches' social identity leadership related to mental health in elite athletes? The mediating role of satisfaction with performance.

It has been found that the way high-performance coaches lead influences both athletes' performance and mental health. However, limited research exists on the Social Identity Approach to leadership in elite sports, despite growing interest in coaching science regarding interpersonal behaviours and leadership. This study investigates the empirical links between coaches' leadership, sport performance and mental health from a social identity approach.

The Catalan initiative for the Earth BioGenome Project: contributing local data to global biodiversity genomics.

The Catalan Initiative for the Earth BioGenome Project (CBP) is an EBP-affiliated project network aimed at sequencing the genome of the >40 000 eukaryotic species estimated to live in the Catalan-speaking territories (Catalan Linguistic Area, CLA). These territories represent a biodiversity hotspot. While covering less than 1% of Europe, they are home to about one fourth of all known European eukaryotic species.

Generation of Orchard and Tree-Child Networks.

Phylogenetic networks are an extension of phylogenetic trees that allow for the representation of reticulate evolution events. One of the classes of networks that has gained the attention of the scientific community over the last years is the class of orchard networks, that generalizes tree-child networks, one of the most studied classes of networks. In this paper we focus on the combinatorial and algorithmic problem of the generation of binary orchard networks, and also of binary tree-child networks.

Chromosome-level assembly and annotation of the Xyrichtys novacula (Linnaeus, 1758) genome.

The pearly razorfish (Xyrichtys novacula), commonly known as raor in the Balearic Islands, is a wrasse within the family Labridae. This fish species has particular biological and socio-cultural characteristics making it an ideal model organism in the fields of behavioural ecology, molecular ecology and conservation biology. In this study, we present the first annotated chromosome-level assembly for this species.

Factorial validity, predictive validity and measurement invariance of the Danish version of the coach-created Empowering Disempowering Motivational Climate Questionnaire (EDMCQ-C).

Purpose: The purpose of this study was to translate and validate a Danish version of the coach-created Empowering and Disempowering Motivational Climate Questionnaire (EDMCQ-C), retest the factor structure and provide further investigation into the psychometric properties in terms of measurement invariance across gender, age and competitive level, reliability and predictive validity.

Methods: The participants were 1719 male and 551 female Danish football players 12-20 years of age ( = 14.81) playing at recreational, medium and elite levels.

Perfectionistic Environments and Irrational Beliefs on the Transition to Elite Athletic Performance: A Longitudinal Study.

This study aimed to longitudinally evaluate talented athletes' levels of perfectionism, irrational beliefs, and motivations with regard to their athletic careers. A total of 390 athletes from U14, U16, and junior categories ( = 15.42) answered shortened versions of the Sport-MPS2, iPBI, and BRSQ during two consecutive seasons, along with questions referring to their current and predicted prioritization of sports and education.

A polynomial invariant for a new class of phylogenetic networks.

Invariants for complicated objects such as those arising in phylogenetics, whether they are invariants as matrices, polynomials, or other mathematical structures, are important tools for distinguishing and working with such objects. In this paper, we generalize a complete polynomial invariant on trees to a class of phylogenetic networks called separable networks, which will include orchard networks. Networks are becoming increasingly important for their ability to represent reticulation events, such as hybridization, in evolutionary history.

Classes of explicit phylogenetic networks and their biological and mathematical significance.

The evolutionary relationships among organisms have traditionally been represented using rooted phylogenetic trees. However, due to reticulate processes such as hybridization or lateral gene transfer, evolution cannot always be adequately represented by a phylogenetic tree, and rooted phylogenetic networks that describe such complex processes have been introduced as a generalization of rooted phylogenetic trees. In fact, estimating rooted phylogenetic networks from genomic sequence data and analyzing their structural properties is one of the most important tasks in contemporary phylogenetics.

EZmito: a simple and fast tool for multiple mitogenome analyses.

Complete mitochondrial genome data are frequently applied to address phylogenetic/phylogeographic issues at different taxonomic levels in ecology and evolution. While sample preparation/sequencing is becoming more and more straightforward thanks to dropping costs for next-generation sequencing (NGS), data preparation and visualization remains a manually intensive step that may lead to errors if improperly conducted. We have elaborated, and here introduce, EZmito, a simple and intuitive, freely accessible Web Server aimed at automating some of these tasks.

Comparative Mitogenomics in (Amphipoda: Crustacea).

We present the sequencing and comparative analysis of 17 mitochondrial genomes of Nearctic and Neotropical amphipods of the genus , most from the Andean Altiplano. The mitogenomes obtained comprised the usual 37 gene-set of the metazoan mitochondrial genome showing a gene rearrangement (a reverse transposition and a reversal) between the North and South American mitogenomes. mitochondrial genomes show the typical AT-richness and strong nucleotide bias among codon sites and strands of pancrustaceans.

VPF-Class: taxonomic assignment and host prediction of uncultivated viruses based on viral protein families.

Motivation: Two key steps in the analysis of uncultured viruses recovered from metagenomes are the taxonomic classification of the viral sequences and the identification of putative host(s). Both steps rely mainly on the assignment of viral proteins to orthologs in cultivated viruses. Viral Protein Families (VPFs) can be used for the robust identification of new viral sequences in large metagenomics datasets.

Phylogenomics of the Hyalella amphipod species-flock of the Andean Altiplano.

Species diversification in ancient lakes has enabled essential insights into evolutionary theory as they embody an evolutionary microcosm compared to continental terrestrial habitats. We have studied the high-altitude amphipods of the Andes Altiplano using mitogenomic, nuclear ribosomal and single-copy nuclear gene sequences obtained from 36 Hyalella genomic libraries, focusing on species of the Lake Titicaca and other water bodies of the Altiplano northern plateau. Results show that early Miocene South American lineages have recently (late Pliocene or early Pleistocene) diversified in the Andes with a striking morphological convergence among lineages.

Complete mitochondrial genome of the pearly razorfish phylogenetic analysis of its placement within the Labridae family.

In this paper, we report the complete mitochondrial genome (17,306 bp) of the pearly razorfish Linnaeus, 1758, a labrid that inhabits tropical and temperate Atlantic waters and the Mediterranean Sea. The circular double-stranded sequence contains the typical teleost gene order with 13 protein-coding genes, 22 tRNA, 2 rRNA, 1 control region, and 2 intergenic spacers between the rRNAs. Using the sequences of all protein-coding genes, we inferred the phylogeny for the Labriade family using 24 labrids and 3 outgroup species that placed in a monophyletic group including species from the Pseudocheilines, Pseudolabrines, and Julidines.

Mitochondrial genomes of twelve species of hyperdiverse weevils.

Mitochondrial genomes of twelve species of weevils are presented, ten of them complete. We describe their gene order and molecular features and test their potential for reconstructing the phylogeny of this hyperdiverse genus comprising > 1,000 species. The complete mitochondrial genomes examined herein ranged from 16,501 bp to 21,007 bp in length, with an average AT content of 64.

Mitogenome phylogenetics in the genus Palaemon (Crustacea: Decapoda) sheds light on species crypticism in the rockpool shrimp P. elegans.

The genus Palaemon comprises worldwide marine and freshwater shrimps and prawns, and some of them are ecologically or commercially important species. Palaemon is not currently a monophyletic group, so phylogenetics and systematics are constantly changing. Species crypticism has been pointed out in several Palaemon species, being the clearest evidence in the European rockpool shrimp P.

[This corrects the article DOI: 10.1371/journal.pcbi.

Generation of Binary Tree-Child phylogenetic networks.

Phylogenetic networks generalize phylogenetic trees by allowing the modelization of events of reticulate evolution. Among the different kinds of phylogenetic networks that have been proposed in the literature, the subclass of binary tree-child networks is one of the most studied ones. However, very little is known about the combinatorial structure of these networks.

The age and diversification of metacrangonyctid subterranean amphipod crustaceans revisited.

The Metacrangonyctidae are a small family of amphipod crustaceans of marine origin found only in subterranean continental waters. They display a broad but punctuated distribution between the Caribbean and the Arabian Peninsula, with major disjunctions either due to vicariance by plate tectonics or to occurrence of recent episodes of long-distance transoceanic dispersal. We re-examine the phylogeny of the family and the time frame for its diversification using mitochondrial genomes in the light of two key taxa recently discovered, from Oman (Arabian Peninsula) and the Rif area of Morocco, respectively.
