Gammaridean Amphipoda of Australia, Part II Gammaridean Amphipoda of Australia, Part II J. LAURENS BARNARD m WUi. SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY • NUMBER 139 SERIAL PUBLICATIONS OF THE SMITHSONIAN INSTITUTION The emphasis upon publications as a means of diffusing knowledge was expressed by the first Secretary of the Smithsonian Institution. In his formal plan for the Insti- tution, Joseph Henry articulated a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge." This keynote of basic research has been adhered to over the years in the issuance of thousands of titles in serial publications under the Smithsonian imprint, com- mencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: Smithsonian Annals of Flight Smithsonian Contributions to Anthropology Smithsonian Contributions to Astrophysics Smithsonian Contributions to Botany Smithsonian Contributions to the Earth Sciences Smithsonian Contributions to Paleobiology Smithsonian Contributions to Zoology Smithsonian Studies in History and Technology In these series, the Institution publishes original articles and monographs dealing with the research and collections of its several museums and offices and of professional colleagues at other institutions of learning. These papers report newly acquired facts, synoptic interpretations of data, or original theory in specialized fields. These pub- lications are distributed by mailing lists to libraries, laboratories, and other interested institutions and specialists throughout the world. Individual copies may be obtained from the Smithsonian Institution Press as long as stocks are available. S. DILLON RIPLEY Secretary Smithsonian Institution SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY • NUMBER 139 Gammaridean Amphipoda of Australia, Part II J. Laurens Barnard SMITHSONIAN INSTITUTION PRESS City of Washington 1974 ABSTRACT Barnard, J. Laurens. Gammaridean Amphipoda of Australia, Part II. Smith- sonian Contributions to Zoology, number 139, 148 pages, 83 figures, 1974.—The following taxa from shallow waters are considered: Amphilochidae: Austropheo- noides J. L. Barnard and a new genus, Moolapheonoides; Dexaminidae: Atylus Leach and Syndexamine Chilton; Gammaridae: Elasmopus Costa, Nuuanu J. L. Barnard and a new genus, Cottesloe; Hyalidae: Allorchestes Dana and Hyale Rathke; Leucothoidae: Leucothoe Leach, Leucothoella Schellenberg and Leucothoides Shoemaker; Stenothoidae: Ausatelson J. L. Barnard, Raumahara J. L. Barnard, Stenothoe Dana and two new genera, Chucullba and Wallametopa. New species of Austropheonoides, Moolapheonoides, Ausatelson, and Rauma- hara confirm their validity as multispecific genera. Rarity of specimens in Australia of the ordinarily common Elasmopus is further explained not only by the diversity of species in the competitive genus Mallacoota J. L. Barnard but in the presence of two species in Cottesloe. The latter genus is closely related to if not antecedent to Nuuanu, a genus composed of incipient interstitial species. In warm-temperate Australia Stenothoe has several sibling species, thus adding to the examples of genera with sibling species described in Part I of this series. Wallametopa may be antecedent to Parametopa of the Mediterranean Sea. Allorchestes is reorganized on a world basis, reduced to 5 species and the others transferred to Hyale. Two new species of Leucothoides are described to boost this genus to 4 species and to separate all Pacific specimens specifically from Atlantic taxa.

  • Effects of Fungicides on Australian Amphipods and Organic Matter Breakdown in Aquatic Environments
    EFFECTS OF FUNGICIDES ON AUSTRALIAN AMPHIPODS AND ORGANIC MATTER BREAKDOWN IN AQUATIC ENVIRONMENTS Submitted by Hung Thi Hong Vu Submitted in fulfillment of the degree of Doctor of Philosophy February 2017 School of BioSciences Faculty of Science The University of Melbourne ABSTRACT Fungicides are used widely in agriculture to control fungal diseases and increase crop yield. After application, fungicides may be transported off site via air, soil and water to ground and surface waters therefore have the potential to contaminate freshwater and marine/estuarine environments. However, relatively little is known about their potential effects on aquatic ecosystems. Amphipods are important in ecosystem service as they help with nutrient recycling through the decomposition of organic matter. The aim of this thesis is to investigate the effects of common fungicides on biological responses in two Australian amphipod species, Allorchestes compressa and Austrochiltonia subtenuis, through a combination of single and mixture laboratory experiments. In addition a field experiment investigated the effects of fungicides on organic matter breakdown. In laboratory studies, juveniles of the marine amphipod A. compressa and the freshwater amphipod A.subtenuis were chronically exposed to two commonly used fungicides, Filan® (active ingredient boscalid) and Systhane™ (active ingredient myclobutanil) at environmentally relevant concentrations. A wide range of endpoints that encompass different levels of biological organization were measured including survival, growth, reproduction, and energy reserves (lipid, glycogen, and protein content). Long term interaction effects of fungicides Filan® and Systhane™ on mature amphipod A. subtenuis was also investigated to evaluate how the results of mixture studies vary between endpoints and to determine suitable endpoints for mixture toxicity studies.

(2004). Cladistic revision of talitroidean amphipods (Crustacea, Gammaridea), with a proposal of a new classification. — Zoologica Scripta, 33, 551–586. This paper reports the results of a cladistic analysis of the Talitroidea s.l., which includes about 400 species, in 96 genera distributed in 10 families. The analysis was performed using PAUP and was based on a character matrix of 34 terminal taxa and 43 morphological characters. Four most parsimonious trees were obtained with 175 steps (CI = 0.617, RI = 0.736). A strict consensus tree was calculated and the following general conclusions were reached. The superfamily Talitroidea is elevated herein as infraorder Talitrida, which is subdivided into three main branches: a small clade formed by Kuria and Micropythia (the Kurioidea), and two larger groups maintained as distinct superfamilies (Phliantoidea, including six families, and Talitroidea s.s., including four). Within the Talitroidea s.s., the following taxonomic changes are proposed: Hyalellidae and Najnidae are synonymized with Dogielinotidae, and treated as subfamilies; a new family rank is proposed for the Chiltoniinae.

Ford 1,* 1 Institute of Marine Science Laboratories, Ferry Road, Eastney, Hants PO4 9LY, UK; [email protected] 2 School of Pharmacy & Biomedical Science, White Swan Road, St. Michael’s Building, Portsmouth PO1 2DT, UK; [email protected] * Correspondence: [email protected] Abstract: Animal behaviour is becoming increasingly popular as an endpoint in ecotoxicology due to its increased sensitivity and speed compared to traditional endpoints. However, the widespread use of animal behaviours in environmental risk assessment is currently hindered by a lack of opti- misation and standardisation of behavioural assays for model species. In this study, assays to assess swimming speed were developed for a model crustacean species, the brine shrimp Artemia franciscana. Preliminary works were performed to determine optimal arena size for this species, and weather lux used in the experiments had an impact on the animals phototactic response. Swimming speed was significantly lower in the smallest arena, whilst no difference was observed between the two larger arenas, suggesting that the small arena was limiting swimming ability. No significant difference was observed in attraction to light between high and low light intensities. Arena size had a significant impact on phototaxis behaviours. Large arenas resulted in animals spending more time in the light side of the arena compared to medium and small, irrespective of light intensity. The swimming speed assay was then used to expose specimens to a range of psychotropic compounds with varying modes Citation: Kohler, S.A.; Parker, M.O.; of action.

This has led to their exclusion from the descriptive work done in the Central and Northern intertidal zones of our country. Hyale is the more conspicuous genus in the intertidal, especially for the sizes some of the species can reach. There are five species known from Chile, H. rubra, H. maroubrae, H. hir- tipalma, H. media and H. grandicornis, none of them endemic.

Introduction Gammaridean amphipods has been a group poorly studied in Chile. The best known genus is Hyale and it is also the most abundant in the rocky intertidal zone of our coast. There are five species known from Chile, living together in most places in the intertidal zone, mainly on algae, some species showing specific level relationships (Lancelloti, personal communication).

ACUTE TOXICITY OF HEAVY METALS TO HYALE CRASSIPES (HELLER, 1866) IN THE BLACK SEA Levent Bat, Fatih Şahin and Ayşah Öztekin University of Sinop Fisheries Faculty, Department of Hydrobiology TR57000 Sinop, Turkey email: [email protected] ABSTRACT: Acute toxicity tests were performed on Hyale crassipes from Karakum shores of Sinop Peninsula in the Black Sea. 24, 48, 72 and 96-h LC50 values were estimated for copper, cadmium and zinc using static bioassay method. This study was the first toxicity study with Hyale crassipes and showed that the species was very sensitive to metals. The results indicated that Cu was more toxic to the amphipods followed by Cd and Zn. Clearly, Hyale crassipes has potential as test species for toxicity studies in Turkish waters.
