Ciona Intestinalis (Linnaeus, 1767) in an Invading Population from Placentia Bay Newfoundland and Labrador
Recruitment patterns and post-metamorphic attachment by the solitary ascidian, Ciona intestinalis (Linnaeus, 1767) in an invading population from Placentia Bay Newfoundland and Labrador By ©Vanessa N. Reid A thesis submitted to the School of Graduate Studies in partial fulfillment of the requirements of the degree of MASTER OF SCIENCE AQUACULTURE MEMORIAL UNIVERSITY OF NEWFOUNDLAND JANUARY 2017 ST. JOHN’S NEWFOUNDLAND AND LABRADOR CANADA ABSTRACT Ciona intestinalis (Linneaus, 1767) is a non-indigenous species discovered in Newfoundland (NL) in 2012. It is a bio-fouler with potential to cause environmental distress and economic strain for the aquaculture industry. Key in management of this species is site-specific knowledge of life history and ecology. This study defines the environmental tolerances, recruitment patterns, habitat preferences, and attachment behaviours of C. intestinalis in Newfoundland. Over two years of field work, settlement plates and surveys were used to determine recruitment patterns, which were correlated with environmental data. The recruitment season extended from mid June to late November. Laboratory experiments defined the growth rate and attachment behaviours of Ciona intestinalis. I found mean growth rates of 10.8% length·d-1. The ability for C. intestinalis to undergo metamorphosis before substrate attachment, forming a feeding planktonic juvenile, thus increasing dispersal time was also found. These planktonic juveniles were then able to attach to available substrates post-metamorphosis. ii TABLE OF CONTENTS -

Bryozoan Studies 2019
BRYOZOAN STUDIES 2019 Edited by Patrick Wyse Jackson & Kamil Zágoršek Czech Geological Survey 1 BRYOZOAN STUDIES 2019 2 Dedication This volume is dedicated with deep gratitude to Paul Taylor. Throughout his career Paul has worked at the Natural History Museum, London which he joined soon after completing post-doctoral studies in Swansea which in turn followed his completion of a PhD in Durham. Paul’s research interests are polymatic within the sphere of bryozoology – he has studied fossil bryozoans from all of the geological periods, and modern bryozoans from all oceanic basins. His interests include taxonomy, biodiversity, skeletal structure, ecology, evolution, history to name a few subject areas; in fact there are probably none in bryozoology that have not been the subject of his many publications. His office in the Natural History Museum quickly became a magnet for visiting bryozoological colleagues whom he always welcomed: he has always been highly encouraging of the research efforts of others, quick to collaborate, and generous with advice and information. A long-standing member of the International Bryozoology Association, Paul presided over the conference held in Boone in 2007. 3 BRYOZOAN STUDIES 2019 Contents Kamil Zágoršek and Patrick N.

Compared to other phyla, little is known about their phylogenetic relationships at both lower and higher taxonomic levels. Hence, an effort is being made to elucidate their phylogenetic relationships. Here, we present newly sequenced nuclear and mitochondrial genes for 21 cheilostome bryozoans. Combining these data with existing orthologous molecular data, we focus on reconstructing the phylogenetic relationships of Fenestrulina and Microporella, two species-rich genera. They are currently placed in Microporellidae, defined by having a semicircular primary orifice and a proximal ascopore. -

This species shows three distinct zooid types during summer: the R (rib), I (intermediate), and S (shield) types. Evidence indicates that zooids commit to development as a given type, rather than transform from one type to another with age. Differences in the frontal spinocyst among the types appear to be mediated by a simple developmental mechanism, acceleration or retardation in the production of lateral costal fusions as the costae elongate during ontogeny. Colonies of all three types were identical, or nearly so, in partial nucleotide sequences of the mitochondrial COI gene (555–631 bp), suggesting that they represent a single species. -

Species in the genus Bugula are globally distributed. They are most abundant in tropical and temperate shallow waters, but representatives are found in polar regions. Seven species occur in the Arctic and one in the Antarctic and species are represented in continental shelf or greater depths as well. The main characters used to define the genus include bird’s head pedunculate avicularia, erect colonies, embryos brooded in globular ooecia and branches comprising two or more series of zooids. Skeletal morphology has been the primary source of taxonomic information for many calcified bryozoan groups, including the Buguloidea. Several morphological characters, however, have been suggested to be homoplastic at dis- tinct taxonomic levels, in the light of molecular phylogenies. -
Individual Autozooidal Behaviour and Feeding in Marine Bryozoans
Individual autozooidal behaviour and feeding in marine bryozoans Natalia Nickolaevna Shunatova, Andrew Nickolaevitch Ostrovsky Shunatova NN, Ostrovsky AN. 2001. Individual autozooidal behaviour and feeding in marine SARSIA bryozoans. Sarsia 86:113-142. The article is devoted to individual behaviour of autozooids (mainly connected with feeding and cleaning) in 40 species and subspecies of marine bryozoans from the White Sea and the Barents Sea. We present comparative descriptions of the observations and for the first time describe some of autozooidal activities (e.g. cleaning of the colony surface by a reversal of tentacular ciliature beating, variants of testing-position, and particle capture and rejection). Non-contradictory aspects from the main hypotheses on bryozoan feeding have been used to create a model of feeding mechanism. Flick- ing activity in the absence of previous mechanical contact between tentacle and particle leads to the inference that polypides in some species can detect particles at some distance. The discussion deals with both normal and “spontaneous” reactions, as well as differences and similarities in autozooidal behaviour and their probable causes. Approaches to classification of the diversity of bryozoan behav- iour (functional and morphological) are considered. Behavioural reactions recorded are classified using a morphological approach based on the structure (tentacular ciliature, tentacles and entire polypide) performing the reaction. We suggest that polypide protrusion and retraction might be the basis of the origin of some other individual activities. Individual autozooidal behaviour is considered to be a flexible and sensitive system of reactions in which the activities can be performed in different combinations and successions and can be switched depending on the situation. -

We examined the type specimens and historical collections holding puzzling Atlantic and Mediterranean material belonging to the genus Schizoretepora Gregory, 1893. We performed a detailed study of the colonial characters and re-describe the resulting species and those that have rarely been found or have poor original descriptions. As a result of this revision, nine species are found in the northeast Atlantic and Mediterranean. Six of them are re-described and illustrated: S. aviculifera (Canu & Bassler, 1930), S. calveti d’Hondt, 1975, S. imperati (Busk, 1884), S. sp. nov.? (= S. -

In this paper we record it for the first time in European waters. The initial discovery was in a marina at Holyhead, North Wales, in July 2010 but S. japonica has since been ob- served abundantly in the Orkney Islands (from May 2011) and, subsequently, at other localities in northern Scotland. In- troduction seems most likely to have been on an ocean-going vessel.

Colony-Wide Water Currents in Living Bryozoa
COLONY-WIDE WATER CURRENTS IN LIVING BRYOZOA by Patricia L Cook British Museum (Natural History), Cromwell Rd., London, SW7 5BD, Gt.Brltain. Résumé Les divers types de courants d'eau des colonies de Bryozoaires sont décrits et analysés. Pour les formes encroûtantes, il en existe au moins trois à l'heure actuelle. Pour les petites colonies de Cyclostomes (Lichenopora), il n'existe qu'un courant centripète se dirigeant vers l'extérieur. Chez certaines Chéilostomes (Hippoporidra) et Cténostomes (Alcyonidium nodosum), des «monticules» sont formés par des groupes de zoïdes dont les couronnes de tentacules sont absentes, réduites ou ne se nourrissent pas. Les « monticules » sont le siège de courants passifs, dirigés vers l'extérieur. Chez d'autres Chéilostomes (Schizoporella, Hippo- porina et Cleidochasma) et des Cténostomates (Flustrellidra hispida), des groupes de zoïdes à couronnes de tentacules hétéromorphes constituent des « cheminées » produisant des courants actifs se dirigeant vers l'extérieur. Des suggestions sont faites concernant une suite d'observations sur les colonies vivantes. Introduction Observation of living colonies is increasingly becoming an essential feature in the study of Bryozoa. Not only is it the primary method of discovering the function of zooids or parts of zooids, it is the first step in testing the established inferences about analogous and homologous structures in preserved material. The study of the functions of whole colonies and the degree and kind of integrative factors contributing to colony-control of these functions is in its early stages. These primary observations can only be made on living colonies. The wide variation in astogeny and ontogeny of structures and their functions in Bryozoa require much further work on many species before any general patterns may become obvious.
