Variation in size of living articulated brachiopods with latitude and depth [PDF]

open access: yes, 2010
Geographical variations in animal characters are one of the main subjects for study in macroecology. Variation with latitude has received special interest.

Monophyly of brachiopods and phoronids: reconciliation of molecular evidence with Linnaean classification (the subphylum Phoroniformea nov.) [PDF]

open access: yes, 2000
Molecular phylogenetic analyses of aligned 18S rDNA gene sequences from articulate and inarticulate brachiopods representing all major extant lineages, an enhanced set of phoronids and several unrelated protostome taxa, confirm previous indications that ...

Molecular evidence that phoronids are a subtaxon of brachiopods (Brachiopoda: Phoronata) and that genetic divergence of metazoan phyla began long before the early Cambrian [PDF]

open access: yes, 2005
Concatenated SSU (18S) and partial LSU (28S) sequences (~2 kb) from 12 ingroup taxa, comprising 2 phoronids, 2 members of each of the craniid, discinid, and lingulid inarticulate brachiopod lineages, and 4 rhynchonellate, articulate brachiopods (2 ...

Complete mitochondrial genome of Bugula neritina (Bryozoa, Gymnolaemata, Cheilostomata): phylogenetic position of Bryozoa and phylogeny of lophophorates within the Lophotrochozoa

open access: yesBMC Genomics, 2009
Background The phylogenetic position of Bryozoa is one of the most controversial issues in metazoan phylogeny. In an attempt to address this issue, the first bryozoan mitochondrial genome from Flustrellidra hispida (Gymnolaemata, Ctenostomata) was ...

New parasitic organisms in a productid brachiopod Eomarginifera lobata from the lower Carboniferous of the Moscow Basin, Russia [PDF]

open access: yesActa Palaeontologica Polonica
Bioclaustrations are among the best ways that parasitic associations are preserved. A new bioclaustration, Haplorygma productidophilia csp. nov., is here described from the ventral interior of the Carboniferous productid brachiopod Eomarginifera lobata ...

Description and figures of new lectotype and paralectotype material of Recent brachiopod Thecidellina maxilla (Hedley, 1899)

open access: yesRecords of the Australian Museum, 2021
The material of Thecidellina maxilla (Hedley, 1899) from the type locality has only been illustrated as line drawings, no images have previously been published.

Comparative Multi-Marker Environmental DNA Metabarcoding of Marine Metazoan Communities: Water vs. Sediment. [PDF]

open access: yesMol Ecol Resour
ABSTRACT This study investigates the metazoan biodiversity in the Southern Adriatic Sea using environmental DNA (eDNA) metabarcoding. Sediment and adjacent water samples were collected from three sites (one pristine, two impacted by human activities) at three distances from the coast across two seasons.

X-ray tomographic microscopy tightens affinity of the early Cambrian Oymurania to the brachiopod stem group [PDF]

open access: yesActa Palaeontologica Polonica, 2017
The geologically rapid biotic evolution in the early Cambrian is marked by the first appearance of major groups of animals in the fossil record (e.g., Budd and Jensen 2000; Kouchinsky et al. 2012).
