A bijection between phylogenetic trees and plane oriented recursive trees [PDF]
arXiv, 2017 Phylogenetic trees are binary nonplanar trees with labelled leaves, and plane oriented recursive trees are planar trees with an increasing labelling. Both families are enumerated by double factorials. A bijection is constructed, using the respective representations a 2-partitions and trapezoidal words.

Single nucleotide polymorphisms in the CDH18 gene affect growth traits in Hu sheep
Animal Research and One Health, EarlyView., 2023 Abstract Growth traits are critical economic traits in sheep. Genetic polymorphism has a great influence on the improvement of sheep traits. The aim of this study was to analyze the effect of cadherin 18 (CDH18) gene polymorphisms on growth traits in Hu sheep.

Antibacterial Siderophores of Pandoraea Pathogens and Their Impact on the Diseased Lung Microbiota
Angewandte Chemie, EarlyView.Genome mining of environmental and pathogenic Pandoraea species identified a conserved NRPS gene cluster and led to the discovery of novel siderophores, pandorabactins, which exert their antibacterial activity by depleting iron from competitors. Bioinformatic analysis of sputum from cystic fibrosis patients coupled with bioassays indicates that ...

On Tree Based Phylogenetic Networks [PDF]
arXiv, 2015 A large class of phylogenetic networks can be obtained from trees by the addition of horizontal edges between the tree edges. These networks are called tree based networks. Reticulation-visible networks and child-sibling networks are all tree based. In this work, we present a simply necessary and sufficient condition for tree-based networks and prove ...

Grass functional traits reflect the long history of fire and grazers in the savannas of Texas
American Journal of Botany, EarlyView.Abstract Premise Understanding relationships among grass traits, fire, and herbivores may help improve conservation strategies for savannas that are threatened by novel disturbance regimes. Emerging theory, developed in Africa, emphasizes that functional traits of savanna grasses reflect the distinct ways that fire and grazers consume biomass ...

Trinets encode tree-child and level-2 phylogenetic networks [PDF]
arXiv, 2012 Phylogenetic networks generalize evolutionary trees, and are commonly used to represent evolutionary histories of species that undergo reticulate evolutionary processes such as hybridization, recombination and lateral gene transfer. Recently, there has been great interest in trying to develop methods to construct rooted phylogenetic networks from ...

The isometry group of phylogenetic tree space is $S_n$ [PDF]
arXiv, 2019 A phylogenetic tree is an acyclic graph with distinctly labeled leaves, whose internal edges have a positive weight. Given a set of n leaves, the collection of all phylogenetic trees with this leaf set can be assembled into a metric cube complex known as phylogenetic tree space, or Billera-Holmes-Vogtmann tree space. In this largely combinatorial paper,

Alterations in gut microbiota and metabolites contribute to postoperative sleep disturbances
Animal Models and Experimental Medicine, EarlyView.In this study, we classified postoperative patients into poor sleepers (PS) and good sleepers (GS) based on the bispectral index (BIS), and transplanted their fecal microbiota to pseudo‐germ‐free rats to analyze the sleep changes in rats and the potential mechanism.
