Abstract Characterization of species diversity of zooplankton is key to understanding,
assessing, and predicting the function and future of pelagic ecosystems throughout the …

In recent years, scientists have made remarkable progress reconstructing the animal
phylogeny. There is broad agreement regarding many deep animal relationships, including …

Globalized infectious diseases are causing species declines worldwide, but their source
often remains elusive. We used whole-genome sequencing to solve the spatiotemporal …

The bacterial heritage of mitochondria, as well as its independent genome [mitochondrial
DNA (mtDNA)] and polycistronic transcripts, led to the view that mitochondrial transcriptional …

Animal mitochondrial DNA (mtDNA) is commonly described as a small, circular molecule
that is conserved in size, gene content, and organization. Data collected in the last decade …

Jellyfish (medusae) are a distinctive life-cycle stage of medusozoan cnidarians. They are
major marine predators, with integrated neurosensory, muscular and organ systems. The …

Background Cnidaria (corals, sea anemones, hydroids, jellyfish) is a phylum of relatively
simple aquatic animals characterized by the presence of the cnidocyst: a cell containing a …

Many years of extensive studies of metazoan mitochondrial genomes have established
differences in gene arrangements and genetic codes as valuable phylogenetic markers …

Hydractinia is a colonial marine hydroid that shows remarkable biological properties,
including the capacity to regenerate its entire body throughout its lifetime, a process made …

Ever since its discovery, the double-stranded DNA contained in the mitochondria of
eukaryotes has fascinated researchers because of its bacterial endosymbiotic origin, crucial …
