Signed: (Simon Reeves) Date: 1/12/2017 II 20/7/18 ABSTRACT Ecologists have long been interested in determining the role biotic relationships play in natural systems. Even Darwin envisioned natural systems as "bound together by a web of complex relations”, noting how “complex and unexpected are the checks and relations between organic beings” (On the Origin of Species, 1859, pp 81-83). Any event or phenomenon that alters the implicit balance in the web of interactions, to any degree, can potentially facilitate a re-organisation in structure that can lead to a wholescale change to the stability of a natural system. As a result of the increasing diversity and intensity of anthropogenic stressors on ecosystems, previously well-understood biotic interactions and emergent ecological functions are being altered, requiring a reappraisal of their effects. -
Pacific Plate Biogeography, with Special Reference to Shorefishes
Pacific Plate Biogeography, with Special Reference to Shorefishes VICTOR G. SPRINGER m SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY • NUMBER 367 SERIES PUBLICATIONS OF THE SMITHSONIAN INSTITUTION Emphasis upon publication as a means of "diffusing knowledge" was expressed by the first Secretary of the Smithsonian. In his formal plan for the Institution, Joseph Henry outlined 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 theme of basic research has been adhered to through the years by thousands of titles issued in series publications under the Smithsonian imprint, commencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: Smithsonian Contributions to Anthropology Smithsonian Contributions to Astrophysics Smithsonian Contributions to Botany Smithsonian Contributions to the Earth Sciences Smithsonian Contributions to the Marine Sciences Smithsonian Contributions to Paleobiology Smithsonian Contributions to Zoo/ogy Smithsonian Studies in Air and Space Smithsonian Studies in History and Technology In these series, the Institution publishes small papers and full-scale monographs that report the research and collections of its various museums and bureaux or of professional colleagues in the world cf science and scholarship. The publications are distributed by mailing lists to libraries, universities, and similar institutions throughout the world. Papers or monographs submitted for series publication are received by the Smithsonian Institution Press, subject to its own review for format and style, only through departments of the various Smithsonian museums or bureaux, where the manuscripts are given substantive review. -
A Checklist of Fishes of the Aldermen Islands, North-Eastern New Zealand, with Additions to the Fishes of Red Mercury Island
13 A CHECKLIST OF FISHES OF THE ALDERMEN ISLANDS, NORTH-EASTERN NEW ZEALAND, WITH ADDITIONS TO THE FISHES OF RED MERCURY ISLAND by Roger V. Grace* SUMMARY Sixty-five species of marine fishes are listed for the Aldermen Islands, and additions made to an earlier list for Red Mercury Island (Grace, 1972), 35 km to the north. Warm water affinities of the faunas are briefly discussed. INTRODUCTION During recent years, and particularly the last four years, over 30 species of fishes have been added to the New Zealand fish fauna through observation by divers, mainly at the Poor Knights Islands (Russell, 1971; Stephenson, 1970, 1971; Doak, 1972; Whitley, 1968). A high proportion of the fishes of northern New Zealand have strong sub-tropical affinities (Moreland, 1958), and there is considerable evidence (Doak, 1972) to suggest that many of the recently discovered species are new arrivals from tropical and subtropical areas. These fishes probably arrive as eggs or larvae, carried by favourable ocean currents, and find suitable habitats for their development at the Poor Knights Islands, where the warm currents that transported the young fish or eggs maintain a water temperature higher than that on the adjacent coast, or islands to the south. Unless these fishes are able to establish breeding populations in New Zealand waters, they are likely to be merely transient. If they become established, they may begin to spread and colonise other off-shore islands and the coast. In order to monitor any spreading of new arrivals, or die-off due to inability to breed, it is desirable to compile a series of fish lists, as complete as possible, for the off-shore islands of the north-east coast of New Zealand. -

Relationships Between Faunal Assemblages and Habitat Types in Broke Inlet, Western Australia
Relationships between faunal assemblages and habitat types in Broke Inlet, Western Australia Submitted by James Richard Tweedley This thesis is presented for the degree of Doctor of Philosophy 2010 B.Sc (Hons) University of Portsmouth (UK) MRes University of Plymouth (UK) Declaration I declare that the information contained in this thesis is the result of my own research unless otherwise cited, and has as its main content work which has not previously been submitted for a degree at any university. __________________________________________ James Richard Tweedley Shifting Sands: The sand bar at the mouth of Broke Inlet in (top) summer and (bottom) winter 2008. Bottom photo by Bryn Farmer. Abstract The work for this thesis was undertaken in Broke Inlet, a seasonally-open estuary on the south coast of Western Australia and the only estuary in that region which is regarded as “near-pristine” (Commonwealth of Australia, 2002). The only previous seasonal studies of the environmental and biotic characteristics of this estuary involved broad-based descriptions of the trends in salinity, temperature and ichthyofaunal characteristics at a limited number of sites. Furthermore, no attempt has been made to identify statistically the range of habitats present in the nearshore and offshore waters of this system, and the extents to which the characteristics of the fish and benthic invertebrate faunas are related to habitat type. These types of data provide not only reliable inventories of the habitat and faunal characteristics of Broke Inlet, but also a potential basis for predicting the likely impact of anthropogenic and climatic changes in Broke Inlet in the future. -

NORMAN2 'Great Barrier Reef Marine Park Authority, PO Box 1379,Townsville, Qld 4810, Australia ([email protected]) 1Department of Zoology, University of Melbourne, Parkville, Vic. 3052, Australia (corresponding author: [email protected]) Abstract Turner, M.L. and Norman, M.D., 1998. Fishes of Wilsons Promontory and Comer Inlet. Victoria: composition and biogeographic affinities. Memoirs of the Museum of Victoria 57: 143-165. A diving survey of shallow-water marine fishes, primarily benthic reef fishes, was under taken around Wilsons Promontory and in Comer Inlet in 1987 and 1988. Shallow subtidal reefs in these regions are dominated by labrids, particularly Bluethroat Wrasse (Notolabrus tet ricus) and Saddled Wrasse (Notolabrus fucicola), the odacid Herring Cale (Odax cyanomelas), the serranid Barber Perch (Caesioperca rasor) and two scorpidid species, Sea Sweep (Scorpis aequipinnis) and Silver Sweep (Scorpis lineolata). Distributions and relative abundances (qualitative) are presented for 76 species at 26 sites in the region. The findings of this survey were supplemented with data from other surveys and sources to generate a checklist for fishes in the coastal waters of Wilsons Promontory and Comer Inlet. 23 I fishspecies of 92 families were identified to species level. An additional four species were only identified to higher taxonomic levels. These fishes were recorded from a range of habitat types, from freshwater streams to marine habitats (to 50 m deep). -
The Mechanisms Leading to Ontogenetic Diet Shift in A
Animal Cells and Systems Vol. 16, No. 4, August 2012, 343Á349 The mechanisms leading to ontogenetic diet shift in a microcanivore, Pterogobius elapoides (Gobiidae) Seung-Ho Choia and Ho Young Sukb* aDepartment of Animal Resources, National Institute of Biological Resources, Incheon 404-708, Korea; bDepartment of Life Sciences, Yeungnam University, Gyeongsan Gyeongsangbuk-do 712-749, Korea (Received 4 December 2011; received in revised form 27 January 2012; accepted 13 February 2012) A variety of fish species undergo an ontogenetic change in prey selectivity, and several potentially interacting factors, including nutrient requirement, microhabitat change, and foraging ability, may account for the occurrence of the shift. Here we examine the foraging ecology and ontogenetic diet shift of a micro-carnivorous goby, Pterogobius elapoides (serpentine goby), dominant component of fish assemblage in shallow rocky areas off the coast in Korea and Japan. Although most other gobies are primarily benthic carnivores, P. elapoides is a semipelagic fish; however, little is known about how those species change their foraging tactics with growth. In our diet analyses, the most common diet was pelagic copepods and benthic amphipods, and diet shift was observed from pelagic to benthic with growth. The ontogenetic diet shift seems to be the result of the preference for energetically more profitable prey in larger-size classes as well as the results of different prey availability due to among-habitat variation in diet. However, differential food preference does not appear to affect individual scope for searching food. Several factors such as predation pressures and interspecific resource partitioning might contribute to the changes in diet observed among size classes, which were included in our ongoing tests. -
Phylogeny of the Plesiopidae (Pisces: Perciformes) with Evidence for the Inclusion of the Acanthoclinidae
BULLETIN OF MARINE SCIENCE, 52(1): 284-326,1993 PHYLOGENY OF THE PLESIOPIDAE (PISCES: PERCIFORMES) WITH EVIDENCE FOR THE INCLUSION OF THE ACANTHOCLINIDAE Randall D. Mooi ABSTRACT Cladistic methods are used to investigate phylogenetic relationships of the Indo-Pacific marine fish family Plesiopidae. Using multiple outgroups, osteological and myological char- acters indicate that plesiopids are monophyletic only with the inclusion of the Acanthoclinidae as the sister group to the genus Plesiops. A new classification lowers the Acanthoclinidae to subfamilial rank, and other monophyletic units are recognized at this same rank to produce the following phylogenctically sequenced classification (included genera in parentheses): Tra- chinopinae (Trachinops), Assessorinae (Assessor), Paraplesiopinae (Paraplesiops, Callople- siops, Steeneichthys), Fraudellinae (Fraudella), Plesiopinae (Plesiops), Acanthoclininae (Acan- thaclinus. Belaneplerygian. Behaps, Acanthoplesiops). This phylogeny suggests that egg mass guarding is plesiomorphic for the family, and that oral incubation in Assessor is autapo- morphic. A diagnosis for the newly defined family is provided. The family Plesiopidae, commonly called longfins, prettyfins, devilfishes, or roundheads, comprises a morphologically diverse group of percoid fishes found in the Indo-Pacific region. There are about 30 species in the family as currently recognized. Adult size ranges from 30 to 300 mm in standard length, and body form varies from narrow and elongate to bulky and heavy bodied. The species also vary considerably in behavior, from diurnal schooling to nocturnal solitary habits. Most are found in relatively shallow water (to 30 m) on coral or rocky reefs. The group is unusual among marine percoids in having demersal eggs with adhesive filaments, characteristic of only four other percoid families: Acantho- clinidae, Grammatidae, Opistognathidae, Pseudochromidae.
