SKELETAL CONVERGENCE IN THUNNIFORM SHARKS, ICHTHYOSAURS, WHALES, AND TUNAS, AND ITS POSSIBLE ECOLOGICAL LINKS THROUGH THE MARINE ECOSYSTEM EVOLUTION

Skeletal convergence in thunniform sharks, ichthyosaurs, whales, and tunas, and its possible ecological links through the marine ecosystem evolution

Abstract Tunas, lamnid sharks, modern whales, and derived ichthyosaurs swisse high strength magnesium powder berry converged on the thunniform body plan, with a fusiform body, lunate caudal fin, compressed peduncle, and peduncle joint.This evolutionary convergence has been studied for a long time but little is known about whether all four clades sh

Association of virulence plasmid and antibiotic resistance determinants with chromosomal multilocus genotypes in Mexican Salmonella enterica serovar Typhimurium strains

Abstract Background Bacterial genomes are mosaic structures composed of genes present in every strain of the same species (core genome), and genes present in some but not all strains of a species (accessory genome).The aim of this study was to compare the genetic diversity of core and accessory genes of a Salmonella enterica subspecies enterica ser
