Many aspects of myxinid taxonomy remain poorly understood, particularly at the genus and subfamily levels. To clarify the validity of two genera (Paramyxine and Notomyxine) and two subfamilies (Rubicundinae and Myxininae), we used a novel supermatrix ...

Three in one: evolution of viviparity, coenocytic placenta and polyembryony in cyclostome bryozoans
Background Placentation has evolved multiple times among both chordates and invertebrates. Although they are structurally less complex, invertebrate placentae are much more diverse in their origin, development and position.

Introduction Among bryozoans, cyclostome anatomy is the least studied by modern methods. New data on the nervous system fill the gap in our knowledge and make morphological analysis much more fruitful to resolve some questions of bryozoan evolution and ...

Why Some Bryozoans Poop Themselves: A Novel Defecation Method in Ctenostome Bryozoans
Defecation process in ctenostome bryozoans with vestibular anus. Faecal pellets are formed in the gut and afterwards pushed via the hindgut onto the retracted lophophore. The latter pushes the pellets outside. ABSTRACT Feeding in animal colonies is a challenging but important aspect in organisms comprised of numerous zooids.

Chromosome evolution at the origin of the ancestral vertebrate genome
Background It has been proposed that more than 450 million years ago, two successive whole genome duplications took place in a marine chordate lineage before leading to the common ancestor of vertebrates. A precise reconstruction of these founding events

ABSTRACT The Mediterranean basin is a hotspot of freshwater endemisms and restricted‐range species, which are among the most threatened worldwide. The Adriatic brook lamprey Lampetra zanandreai is a non‐parasitic, freshwater‐resident lamprey whose core distribution lies in the Po River basin (Northern Italy).

ABSTRACT The rapid growth of genome sequencing has outpaced the development of efficient annotation tools, especially for species lacking transcriptome data. To address this challenge, we present QuickProt, a fast, accurate and user‐friendly homology‐based protein annotation tool.
