Community vertical stratification drives temporal taxonomic and phylogenetic beta diversity in a mixed broadleaf-conifer forest

open access: yesFrontiers in Ecology and Evolution, 2023
Temporal change of beta diversity provides a better understanding of the extent and consequences of species composition in forest communities with the ongoing global climate change.

Rearrangement operations on unrooted phylogenetic networks [PDF]

open access: yesTheory and Applications of Graphs, Vol. 6 Iss. 2 Article 6. (2019), 2019
Rearrangement operations transform a phylogenetic tree into another one and hence induce a metric on the space of phylogenetic trees. Popular operations for unrooted phylogenetic trees are NNI (nearest neighbour interchange), SPR (subtree prune and regraft), and TBR (tree bisection and reconnection).

The neighbor-joining method: a new method for reconstructing phylogenetic trees.

open access: yesMolecular biology and evolution, 1987
A new method called the neighbor-joining method is proposed for reconstructing phylogenetic trees from evolutionary distance data. The principle of this method is to find pairs of operational taxonomic units (OTUs [= neighbors]) that minimize the total ...

Ancient and modern hybridization between Lucilia sericata and L. cuprina (Diptera: Calliphoridae)

open access: yesEuropean Journal of Entomology, 2013
There are important but inconsistent differences in breeding site preference between the blow flies Lucilia sericata (Meigen, 1826) and L. cuprina (Wiedemann, 1830) (Diptera: Calliphoridae) that have significance for medical and veterinary science. These

Effects of environment and metacommunity delineation on multiple dimensions of stream fish beta diversity

open access: yesFrontiers in Ecology and Evolution, 2023
IntroductionBeta diversity represents changes in community composition among locations across a landscape. While the effects of human activities on beta diversity are becoming clearer, few studies have considered human effects on the three dimensions of ...

Isolation and Molecular Identification of Bacterial Strains to Study Biofilm Formation and Heavy Metals Resistance in Saudi Arabia

open access: yesJournal of Pure and Applied Microbiology, 2019
Heavy metals found in nature and the excessive accumulations of heavy metals have an impact on humans and animals. Different effects resulted from the toxicity of heavy metal, that damage the functioning of different organs: brain, lungs, kidney and ...

Genetic and phylogenetic relationship of an American caprine rotavirus B strain with equine rotavirus B

open access: yesFrontiers in Virology, 2023
Rotaviruses (RVs) are significant enteric pathogens of humans and animals. In March 2021, the University of Kentucky Veterinary Diagnostic Laboratory (UKVDL) received a fecal sample from a 1-week-old goat kid with diarrhea from a farm with 5 additional ...

Genome-wide identification and expression analyses of phenylalanine ammonia-lyase gene family members from tomato (Solanum lycopersicum) reveal their role in root-knot nematode infection

open access: yesFrontiers in Plant Science, 2023
Phenylalanine ammonia-lyase (PAL) is a key enzyme and rate-limiting enzyme of phenylpropanoid metabolism, which is a very important pathway in plants, and the secondary products it produces play an important role in plant growth and development, disease ...
