Tubular sprouting as a mode of vascular formation in a colonial ascidian (tunicata) [PDF]
Developmental Dynamics, 2007 AbstractAlthough phylogenetically related to vertebrates, invertebrate chordate tunicates possess an open circulatory system, with blood flowing in lacunae among organs. However, the colonial circulatory system (CCS) of the ascidian Botryllus schlosseri runs in the common tunic and forms an anastomized network of vessels, defined by simple epithelium ...

Colonial ascidians strongly preyed upon, yet dominate the substrate in a subtropical fouling community. [PDF]
Proc Biol Sci, 2019 Higher diversity and dominance at lower latitudes has been suggested for colonial species. We verified this pattern in species richness of ascidians, finding that higher colonial-to-solitary species ratios occur in the tropics and subtropics.

Identification of Ascidians (Tunicata: Ascidiacea) around Larak Island in the Persian Gulf [PDF]
بومشناسی آبزیان, 2016 Despite the variety of marine organisms recorded from the Persian Gulf, acidians located along the Persian Gulf have not received much attention. We collected Ascidian samples from four sites along Larak Island (Persian Gulf) using Scuba diving and ...

Why Some Bryozoans Poop Themselves: A Novel Defecation Method in Ctenostome Bryozoans. [PDF]
J MorpholDefecation 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.

Experimental Evidence for a Metal-Related Function of a Cyanobactin. [PDF]
Angew Chem Int Ed EnglCyanobactins such as patellamides are produced by cyanobacteria profusely and have been studied extensively, but almost exclusively for their cytotoxic properties. Discussed is unprecedented experimental evidence for a metal‐related biological function – likely CO2 transport from the ascidian to the cyanobacterial symbiont.

An elongated COI fragment to discriminate botryllid species and as an improved ascidian DNA barcode
Scientific Reports, 2021 Botryllids are colonial ascidians widely studied for their potential invasiveness and as model organisms, however the morphological description and discrimination of these species is very problematic, leading to frequent specimen misidentifications.

Coloniality has evolved once in Stolidobranch Ascidians [PDF]
Integrative and Comparative Biology, 2006 Ascidians exhibit a rich array of body plans and life history strategies. Colonial species typically consist of zooids embedded in a common test and brood large, fully developed larvae, while solitary species live singly and usually free-spawn eggs that develop into small, undifferentiated larvae.

Morphological Study and 3D Reconstruction of the Larva of the Ascidian Halocynthia roretzi
Journal of Marine Science and Engineering, 2021 The swimming larva represents the dispersal phase of ascidians, marine invertebrates belonging to tunicates. Due to its adhesive papillae, the larva searches the substrate, adheres to it, and undergoes metamorphosis, thereby becoming a sessile filter ...

Subcloning colonial ascidians v2
, 2021 We have been subcloning colonial ascidians since some time already, till now - with a lot of success. This protocol has been ruinously used by many of our co-workers.
