Information-theoretic signatures of biodiversity in the barcoding gene
, 2018 The COI mitochondrial gene is present in all animal phyla and in a few others, and is the leading candidate for species identification through DNA barcoding.

Differential expression of conserved germ line markers and delayed segregation of male and female primordial germ cells in a hermaphrodite, the leech helobdella. [PDF]
, 2013 In sexually reproducing animals, primordial germ cells (PGCs) are often set aside early in embryogenesis, a strategy that minimizes the risk of genomic damage associated with replication and mitosis during the cell cycle.

Here, There and Everywhere: The Radiolar Eyes of Fan Worms (Annelida, Sabellidae).
Integrative and Comparative Biology, 2016 Fan worms (Annelida: Sabellidae) possess some of the strangest eyes in nature. Their eponymous fans are composed of two sets of radiolar tentacles that project from the head up out of the worm's protective tube into the water column.

Environmental DNA, Volume 7, Issue 3, May/June 2025.We assessed whether we can combine the advantages of both bulk and eDNA metabarcoding, that is, obtaining a local signal and being minimally invasive, to improve local invertebrate detections in streams using water samples. We quantified eDNA release over time after a short incubation in water for single species using qPCR and for bulk samples using ...

New systematic results based on chaetal hard structures in Mesochaetopterus (Polychaeta)
Scientia Marina, 2006 Two kinds of chaetal hard structures have been analysed within the genus Mesochaetopterus (Chaetopteridae, Polychaeta): the specialised chaetae of the fourth segment of the anterior part of the body (i.e. the A4 segment) and the uncinal plates present on

Molecular Ecology Resources, Volume 25, Issue 4, May 2025.ABSTRACT Molecular methods such as DNA/eDNA metabarcoding have emerged as useful tools to document the biodiversity of complex communities over large spatio‐temporal scales. We established an international Marine Biodiversity Observation Network (ARMS‐MBON) combining standardised sampling using autonomous reef monitoring structures (ARMS) with ...

Neural architecture of Galathowenia oculata Zach, 1923 (Oweniidae, Annelida)
Frontiers in Zoology, 2016 BackgroundOweniids are marine tubeworms burrowing in muddy sediments that in current phylogenies form an early branching lineage within Annelida. Little is known about their general morphology, in particular the nervous system.
