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 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.

Antarctic Sessile Marine Benthos: Colonisation and Growth on Artificial Substrata Over Three Years
MARINE ECOLOGY PROGRESS SERIES Vol. 316: 1–16, 2006 Published July 3 Mar Ecol Prog Ser OPENPEN ACCESSCCESS FEATURE ARTICLE Antarctic sessile marine benthos: colonisation and growth on artificial substrata over three years David A. Bowden*, Andrew Clarke, Lloyd S. Peck, David K. A. Barnes Natural Environment Research Council, British Antarctic Survey, High Cross, Madingley Road, Cambridge CB3 0ET, UK ABSTRACT: The development of sessile invertebrate assemblages on hard substrata has been studied exten- sively in temperate and tropical latitudes. Such studies provide insights into a range of ecological processes, and the global similarity of taxa recruiting to these assem- blages affords the potential for regional-scale com- parisons. However, few data exist for high latitude assemblages. This paper presents the first regularly resur- veyed study of benthic colonisation from within the Antarctic Circle. Acrylic panels were deployed horizon- tally on the seabed at 8 and 20 m depths at each of 3 loca- tions in Ryder Bay, Adelaide Island, SW Antarctic Peninsula (67° 35’ S, 68° 10’ W). Assemblages colonising upward- and downward-facing panel surfaces were photographed in situ from February 2001 to March 2004. Assemblages were dominated by bryozoans and spiror- Bowden and co-workers present the first successful benthic bid polychaetes. Total coverage after 3 yr ranged from 6 to colonisation study from within the Antarctic Circle. They 100% on downward-facing surfaces but was <10% on all describe a system governed by extremely slow and highly upward-facing surfaces. Overall colonisation rates were seasonal growth, and a range of post-settlement disturbances in which succession is more predictable than in comparable up to 3 times slower than comparable temperate latitude temperate or tropical assemblages. -

BEU2 1Istituto di Geologia Marina, Consiglio Nazionale delle Ricerche, via Gobetti 101, I-40129 Bologna - Italy 2Institute of Geological & Nuclear Sciences, P.O. Box 30 368, Lower Hutt - New Zealand Received 5 March 2001; accepted in revised form 3 July 2001 Abstract - CRP-3 cored Palaeogene strata to 823 metres below the sea floor (mbsf), before passing through Devonian bedrock (Beacon Supergroup) to a depth of 939 mbsf. Palaeogene body fossils have been identified at 239 horizons in the core. The best preserved macrofossils from the core help elucidate the taxonomy, chronology and biogeography of Cenozoic ecosystems of Antarctica, although poor preservation prevents identification to species level in most cases. The lithostratigraphic unit (LSU) of the core top (LSU 1.1) contains an almost monospecific modiolid assemblage, similar to mussel beds recovered in the bottom part of the CRP-2/2A core. These semi-infaunal mussels appear to be conspecific, apparently indicating the same age (Early Oligocene) and environment, i.e., a deep muddy shelf characterized by high turbidity and dysoxic/anoxic bottom conditions (high H2S sediment content). LSU 1.2 contains reasonably diverse assemblages representing inner/middle shelf environments dominated by epifaunal suspension feeders. LSU 2.1 contains low-diversity assemblages of suspension feeders (bivalves, brachiopods and bryzoans), probably indicating inner/middle shelf environments. LSU 3.1 contains assemblages including infaunal and epifaunal suspension feeders (bivalves, including a scallop, ?Adamussium n.sp., and solitary corals) and infaunal deposit-feeders, possibly indicating deposition on a deep muddy shelf. -

We tabulate all known taxa chronologically, summarize stratigraphical and geographical distributions, and comment on the main morphological innovations that appeared in pre-Cenomanian times. Most early cheilo- stomes are classified in the suborder Malacostegina. Early cheilostomes were morphologically simple and low in diversity, but were geographically widespread. These features can be explained by the possession of a long-living planktotrophic larval stage, as in Recent malacostegans. -

Det har länge varit svårt att utnyttja och undersöka något på havets bottnar. När resurser och utrustning under de senaste årtiondena blivit bättre har vi sett att här finns mycket att finna. Man har exempelvis hittat havslevande djur som kan skydda sig från parasiter utan att ha ett immunförsvar. De har tagit hjälp av bakterier som tillverkar olika giftiga ämnen som sprids i djurets omgivningar eller stannar på dess yta, vilket ger ett skydd från vissa rovdjur. -

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.
