Leafy Bryozoans and Other Bryozoan Species in General Play an Important Role in Marine Ecosystems
These wash up on the shoreline looking like Flustra foliacea clumps of seaweed. Class: Gymnolaemata Order: Cheilostomata Family: Flustridae Genus: Flustra Distribution Flustra foliacea has a wide It is common to the coastal areas of northern Europe especially distribution in the North in the North Sea. Countries include Britain, Ireland, Belgium, Atlantic Ocean, on both the Netherlands, and France. It does not continue any further south European and American than northern Spain. In Canada it is in Nova Scotian waters, sides. including the Bay of Fundy and the Minas Basin. Habitat It most frequently occurs between 10-20 m water depths. It is This is a cold water species. typically found on the upper faces of moderately wave-exposed It prefers high salinity bedrock or boulders subjected to moderately strong tidal waters, but can also found streams. These rocky patches may be interspersed with gravelly in areas with lower salinity. sand patches, causing a scouring effect. Most Bryozoans live in It occupies sublittoral salt water, and of the 20 or so freshwater species found in North (below low tide) areas. America, most are found in warm-water regions attached to plants, logs, rocks and other firm substrates. Food This species is an active This is a colonial animal composed of various types of zooids. A suspension feeder. They zooid is a single animal that is part of the colony. The basic consume phytoplankton, zooids are the feeding ones, called the autozooid. Each of these detritus, and dissolved has a mouth and a feeding structure, the lophophore, which is organic matter. -

Marine Flora and Fauna of the Northeastern United States Erect Bryozoa
NOAA Technical Report NMFS 99 February 1991 Marine Flora and Fauna of the Northeastern United States Erect Bryozoa John S. Ryland Peter J. Hayward U.S. Department of Commerce NOAA Technical Report NMFS _ The major responsibilities of the National Marine Fisheries Service (NMFS) are to monitor and assess the abundance and geographic distribution of fishery resources, to understand and predict fluctuations in the quantity and distribution of these resources, and to establish levels for their optimum use. NMFS i also charged with the development and implementation of policies for managing national fishing grounds, development and enforcement of domestic fisheries regulations, urveillance of foreign fishing off nited States coastal waters, and the development and enforcement of international fishery agreements and policies. NMFS also assists the fishing industry through marketing service and economic analysis programs, and mortgage in surance and ve sel construction subsidies. It collects, analyzes, and publishes statistics on various phases of the industry. The NOAA Technical Report NMFS series was established in 1983 to replace two subcategories of the Technical Reports series: "Special Scientific Report-Fisheries" and "Circular." The series contains the following types of reports: Scientific investigations that document long-term continuing programs of NMFS; intensive scientific report on studies of restricted scope; papers on applied fishery problems; technical reports of general interest intended to aid conservation and management; reports that review in considerable detail and at a high technical level certain broad areas of research; and technical papers originating in economics studies and from management investigations. Since this is a formal series, all submitted papers receive peer review and those accepted receive professional editing before publication. -

Bryozoans in Archaeology 1. Introduction 2. Bryozoan Biology
Reprinted from Internet Archaeology, 35 (2013) Bryozoans in Archaeology Matthew Law School of History, Archaeology and Religion, Cardiff University, Colum Drive, Cardiff, CF10 3EU. Email: [email protected] ORCID: 0000-0002-6127-5353 Summary Bryozoans (Phylum Bryozoa) are colony-forming invertebrates found in marine and freshwater contexts. Many are calcified, while some others have chitinous buds, and so have archaeological potential, yet they are seldom investigated, perhaps due to considerable difficulties with identification. This article presents an overview of bryozoans, as well as summarising archaeological contexts in which bryozoans might be expected to occur, and highlighting some previous work. It also presents methods and directions to maximise the potential of bryozoans in archaeological investigations. Features o Keywords: Bryozoa, environmental archaeology, palaeoecology, biological remains, marine shells, freshwater sediments, marine sediments 1. Introduction Bryozoans (Phylum Bryozoa), also known as sea mats or moss animals and formerly as Polyzoa or Entroprocta, are colony-forming sessile invertebrates, comprising communities of separate individuals known as zooids. There are around 6000 living species known in the world (Benton and Harper 2009, 314). Most are marine, although brackish and freshwater species exist. Generally, they occur on hard substrates such as rocks, shells and the fronds of seaweeds, although there are forms that live on mud and sand. Many are calcified, and others have chitinous buds, and have the potential to be preserved in archaeological contexts, yet they are seldom investigated, perhaps due to considerable difficulties with identification. Considerably more work has been done on geological assemblages and more still on living colonies; however, in general the group is not well known (Francis 2001, 106). -

Acknowledgements Appendix 1: Flustra foliacea collection at the Natural History Museum Appendix 2: Work protocol chart 1. Introduction Museums give pleasure by evoking wonder and awe. They allow us to explore the world, making other cultures and places real and tangible. In this ever changing world they give users a strong sense of place, identity and belonging based on the past. Museums have a considerable economic impact and stimulate science, creativity and industry. In this paper we focus on one of their major functions - providing evidence, ideas and opportunities for research and learning. Museum collections represent huge databases accumulated over time thus providing an historical perspective for modern surveys. As old collections become used and studied, old information is corrected in a continuous validation process that represents an important component of our general knowledge. Collections are especially important for groups that are either too big (i.e. -
Biology and Video Surveys of North Hoyle Wind Farm
Biology & Video Surveys of North Hoyle Wind Turbines 11th – 13th August 2004 by Francis Bunker Survey team: Francis Bunker (survey leader) Tom Mercer Jennifer Jones James Perrins Project management and report editing by CMACS Ltd MarineSeen Estuary Cottage, Bentlass, Hundleton, Pembrokeshire SA71 5RN Synopsis • This document reports on an investigation by divers into the marine colonisation of structures at the North Hoyle offshore wind farm, north Wales. The study took place between August 11th and 13th 2004 after the wind turbines had been in place for approximately 1 year and a meteorological mast for 3 months. In all cases the turbines were turning at the time of the visits, although not necessarily generating. At the time windspeeds were generally low and power generation was intermittent. • Detailed descriptive information was obtained from two turbines and a recently installed meteorological mast using standard Phase 2 methodology. A further 4 turbines were surveyed briefly for comparison and to determine the zonation of communities. Digital underwater video was taken of all structures studied. A table of species identified together with abundances is presented. • Although there was some variation between the turbines, a characteristic vertical zonation of communities was found to occur up and down these artificial structures. The dominant species included the barnacle Balanus crenatus, the amphipod Jassa falcata and the mussel Mytilus edulis. The common starfish Asterias rubens and the sea anemones Metridium senile, Sagartia elegans and Sagartia troglodytes were also conspicuous. • A series of 0.01 m2 quadrats were scrapped clear of attached organisms in each zone (where practicable) on two turbines and the met mast.
