We are delighted that you could join us in the UNESCO World Heritage Site of Liverpool for what is sure to be a fantastic meeting, showcasing the best aquatic science from around the globe. As a one-off meeting with we are very proud to have attracted nearly 300 delegates from 114 institutes in 30 countries. We feel that we have a balanced programme with representation across a range of freshwater, transitional and marine habitats from industry, students, early career and established scientists. We are also very proud to say that we have excellent gender balance with almost 50% female delegates. The overarching theme of this conference is "evolution, interactions and global change in aquatic ecosystems", with the following themes: • Evolutionary Biology • Dispersal and Connectivity • Food Webs and Trophic Dynamics • Biodiversity, Ecosystem Functioning Services • Global Environmental Change • Fisheries and Aquaculture • Conservation, Management and Policy Inside this booklet you will find all of the necessary information required to navi- gate around the conference throughout the week. There are too many restaurants to even begin to try to advise you where to eat, but rest assured that there is plenty of choice to suit every palate. Please also see the Liverpool Pub Guide for suggestions of places to visit on the "Cultural Walk: the Imbibing Emporiums of Liverpool". We have specifically selected some cracking pubs that touch on some of the historic and cultural aspects of the city. We hope that you enjoy the walk and get an appreciation for this fantastic city. Please feel free to come and chat to any of the organising committee if you need information on anything throughout the week.

We hope you enjoy the city and the conference. The University of Liverpool has a long tradition in both marine and freshwater science that continues strongly to this day. The first Oceanography Department in the UK was opened in 1919 supported by strong endowment from Sir William Herdman FRS. Herdman who was Professor of Zoology at the University College Liverpool was also a leading light in the Liverpool Marine Biology Committee which ran a laboratory on PuffinIslandoff Anglesey and then founded a Marine Biological Station on the Isle of Man in 1892. This was subsequently transferred to the University in 1919 on formation of the Oceanography Department. The laboratory became the first department in the United Kingdom offering single Honours degrees in Marine Biology. Sadly the Port Erin Marine Laboratory closed in 2006, but Marine Biology has successfully transferred to the main campus in the School of Environment, benefitting much from its co-location with the oceanog- raphers. The National Oceanography Centre, Liverpool (formerly the Proudman Oceanographic Laboratory) has a long history going back to the Liverpool Obser- vatory and Tidal Institute focussing on tidal predictions, sea level measurements and modelling nearshore and shelf shore oceanography and sediment dynamics. Equally strong is the history of work on algae and aquatic plants in both marine and freshwater systems in the former Botany Department. In Zoology, Noel Hynes pioneered the use of biological indicators of water quality and much else in the 1950s and 1960s. There was ground breaking work on freshwater fish by Jack Jones and colleagues. Brian Moss has continued the tradition with work on still waters in recent years. Thus Liverpool is a fitting venue for a meeting deliberately setting out to link ma- rine and freshwater ecology. Several of the organising committee have links with Liverpool - directly or indirectly. My personal links stretch back to 1973 when as a17yearoldIcametoLiverpooltostudy(wellsomeofthetime)marinebiology - but also did much freshwater biology in the first two years. Thus on behalf of the organising committee - welcome to the Aquatic Biodiversity and Ecosystems Conference 2015. The meeting partially follows up on the Plant-Animal Interactions conference that was run 25 years ago. It is deliberately broader in scope - hopefully integrating concepts and practice across freshwater and marine ecology. Just as important, it is an opportunity to sample what the city has to offer - some of it in Imperial rather than SI units.

  • (Gastropoda: Littorinidae) in the Temperate Southern Hemisphere: the Genera Nodilittorina, Austrolittorina and Afrolittorina
    © Copyright Australian Museum, 2004 Records of the Australian Museum (2004) Vol. 56: 75–122. ISSN 0067-1975 The Subfamily Littorininae (Gastropoda: Littorinidae) in the Temperate Southern Hemisphere: The Genera Nodilittorina, Austrolittorina and Afrolittorina DAVID G. REID* AND SUZANNE T. WILLIAMS Department of Zoology, The Natural History Museum, London SW7 5BD, United Kingdom [email protected] · [email protected] ABSTRACT. The littorinine gastropods of the temperate southern continents were formerly classified together with tropical species in the large genus Nodilittorina. Recently, molecular data have shown that they belong in three distinct genera, Austrolittorina, Afrolittorina and Nodilittorina, whereas the tropical species are members of a fourth genus, Echinolittorina. Austrolittorina contains 5 species: A. unifasciata in Australia, A. antipodum and A. cincta in New Zealand, and A. fernandezensis and A. araucana in western South America. Afrolittorina contains 4 species: A. africana and A. knysnaensis in southern Africa, and A. praetermissa and A. acutispira in Australia. Nodilittorina is monotypic, containing only the Australian N. pyramidalis. This paper presents the first detailed morphological descriptions of the African and Australasian species of these three southern genera (the eastern Pacific species have been described elsewhere). The species-level taxonomy of several of these has been confused in the past; Afrolittorina africana and A. knysnaensis are here distinguished as separate taxa; Austrolittorina antipodum is a distinct species and not a subspecies of A. unifasciata; Nodilittorina pyramidalis is separated from the tropical Echinolittorina trochoides with similar shell characters. In addition to descriptions of shells, radulae and reproductive anatomy, distribution maps are given, and the ecological literature reviewed.

With Text-figures 1-10 Chondracanthidae is a family of highly transformed cyclopoid copepods that are found exclusively on marine demersal fish. Although a complete life history of this family of copepods is still unknown, it seems, judging from the available infor­ mation of their larval development, that the parasites do not require an intermediate host. Both adult and larva are found in the oral-branchial cavity of the fish, attaching to the host tissue by their powerful, hook-like second antenna. Although a few species are known to live in the nasal cavity, they have not been found on the body surface or fins of the fish. The male is characteristically dwarf and attaches to the genital area of the female throughout its life. In many species, the transformed female has a pair of small processes on the posteroventral surface of the trunk just in front of the genital segment. The pigmy male holds on to one of these two processes by its transformed hook-like second antennae.

However, canopy-forming algae are experiencing a general global decline, mostly driven by human pressures on coastal ecosystems and global changes. In contrast with their high ecological relevance, little is known about how their genetic diversity, dispersal and connectivity can be affected by global changes, despite the expected consequences for population resilience. I focused on studying brown macroalgae of the genus Cystoseira, one of the leading canopy-forming seaweed genera along European coasts, coupling molecular and ecological approaches to understand several processes that affect these marine forests.

The species are: Chondracanthus fnerluccii, Brachiel/a merluccii and Parabrachiella australis. The parasites importance as indicators of the affinities between hakes is discussed. Various hypotheses concerning the origin of the genus Merluccius are presented. INTRODUCTION Studies on parasites as biological indicators of their host's population status, affinities, migrations, origin and zoogeographic distribution are a valuable method to explain many problems of biology of fish. The parasitic species of a narrow specificity are particularly interesting as indicators. The parasitic copepods of the genera Chondracanthus, Brachiella and Parabrachiellaappear to play such a role in hake. During the investigations on species variability within the genus Merluccius from the Atlantic and Mediterranean Sea (Soliman, 1973), the parasitic copepods were collected in order to utilize them as possible indicators of specific affiliations and affinities between the hakes investigated. MATERIALS AND METHOD The parasites were collected in 1971 � 1973 from mouth and gill cavities of the fishes exami1ied. 32 Jadwiga Grabda, Ibrahim Abdel Fattah Mahmoud Soliman Table 1 and the chart enclosed (Fig. 1) summarize number of fishesexamined, fishing grounds and catching time of particular hake stocks. 45' "1' tJt�H m-����;-��������-f-������������-"<t--==,__���11,' o' ,s· 45' Fig.

Taonia abbottiana differs from other species of the genus in having (1) sporangia raised above the surface layer on a stalk composed of two cells, and (2) in addition having a surface cortical layer of differentiated cells that are smaller than those of the medullary layers. Taonia abbottiana has often been confused with Stypopodium zonate, but the two differ anatomically in the development of cells directly behind the growing margin and, when living at similar depths, T.
