The survey locations were modified from the four previous survey sites from 2008-2012, in accordance with approvals and requests from the South Australian Environment Protection Authority (EPA) to focus on subtidal reef habitats at the saline diffuser reef and four reference reefs within the Adelaide metropolitan waters. Baited remote underwater video systems (BRUVS) were used to collect data for this 2015 autumn survey. This autumn survey will become the new baseline of fish assemblage data as the previous monitoring locations were all outside of the area of known hypersaline plumes. The new monitoring locations include the diffuser reef at Port Stanvac as the impact site (DPR) and four reference reefs (two to the north and two to the south). The reference reefs of Glenelg Tyre Reef, Seacliff Reef, Port Noarlunga Reef (PNR) and Port Noarlunga Tyre Reef­ Lumbs were selected to capture a spread of sites that represented artificial and natural reefs in similar depths to the DPR. The PNR site is also protected under the Marine Parks Act 2007 as a Sanctuary Zone and should therefore have the same level of protection from fishing as the DPR which lies within the Adelaide Desalination Plant Exclusion Zone. During this study, a total of 2950 fish were counted and 44 species identified from 29 families. The most prevalent family of fish across the survey were the Monacanthidae or leatherjackets. They were also the most abundant fish. By focusing on the subtidal reef communities rather than continuing to include soft-bottom seagrass habitats, some of the variability between reference sites has been removed. There was still however differences between reef types of artificial or natural reef assemblages as well as preferences of some species for southern over northern reefs. This was most evident for the juveniles of the species T. novaezelandiae P. me/bournensis M. hippocrepis and Pempheris sp. as well as all stages of the Bluefin leatherjacket T. degeni which were present in high numbers. There were no observations of Port Jackson sharks (Heterodontus portusjacksoni) as there had been in previous years and this may be due to the change from monitoring soft bottom communities to focusing on reef habitats. By focusing on deeper water (15-20 m) reef habitats, the likelihood of recording different species to previous years has increased; the spring survey will confirm whether there are seasonal differences between surveys sites or if there is a real shift in fish assemblages within the Adelaide metropolitan subtidal reefs. Based on the results of this autumn survey, there were no statistically significant differences between the DPR impact site and the reference reefs fish assemblages. The total abundance of fish recorded at DPR was however significantly higher than any of the reference reefs and is likely a result of the reduced fishing pressure at the site due to the Exclusion Zone. There appeared to be no detrimental effects of the ADP discharge on the fish assemblages at DPR and the artificial reef appears to be enriching the fish assemblages in its immediate area.

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.

  • UNIVERSITY of CALIFORNIA Los Angeles
    UNIVERSITY OF CALIFORNIA Los Angeles Evolution of the boxfish carapace: functional consequences of shape A thesis submitted in partial satisfaction of the requirements for the degree of Master of Science in Biology by Tina Ashley Marcroft 2015 ABSTRACT OF THE THESIS Evolution of the boxfish carapace: functional consequences of shape by Tina Ashley Marcroft Master of Science in Biology University of California, Los Angeles, 2015 Professor Michael Edward Alfaro, Chair Boxfishes are a group of heavily armored Tetraodontiform fishes that are highly variable in shape. Disparification of shape could be driven by a simple performance trade-off between its two hypothesized primary functions: protection from predation and maneuverability. Alternatively, disparification could be driven by many-to-one mapping of shape to performance, where a relaxation in morphological constraint where many of morphologies have the same performance. We tested this by isolating the major features of the boxfish carapace shape and tested for their correlation to performance, as well as for a negative correlation between performances. We found that some features were correlated but very weakly, and that the two performances did trade-off but also weakly. This weak correlation primarily suggests that many- to-one mapping of shape to performance is driving disparification, which was unobserved in continuous 3D shape systems until this study. ii The thesis of Tina Ashley Marcroft is approved. Blaire Van Valkenburgh David K. Jacobs Michael Edward Alfaro, Committee Chair University of California, Los Angeles 2015 iii I dedicate this thesis to Carrie Umetsu, Joseph Aprill, Mai Nguyen, Princess Gilbert, Francisca Wufu, Deb Pires, Jonathan Chang, Herbert Icasiano, and many others, without whose unwavering emotional and professional support I would not have completed this text.

These MPAs include 13 Marine National Parks (MNPs), 11 Marine Sanctuaries (MSs), 3 Marine and Coastal Parks, 2 Marine Parks, and a Marine Reserve, and together these account for 11.7% of the Victorian marine environment. The highly protected Marine National Park System, which is made up of the MNPs and MSs, covers 5.3% of Victorian waters and was proclaimed in November 2002. This system has been designed to be representative of the diversity of Victoria’s marine environment and aims to conserve and protect ecological processes, habitats, and associated flora and fauna. The Marine National Park System is spread across Victoria’s five marine bioregions with multiple MNPs and MSs in each bioregion, with the exception of Flinders bioregion which has one MNP.

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).

  • Habitat Preferences and Fitness Consequences for Fauna Associated with Novel Marine Environments
    Habitat preferences and fitness consequences for fauna associated with novel marine environments Luke T Barrett orcid.org/0000-0002-2820-0421 Submitted in total fulfilment of the requirements of the degree of Doctor of Philosophy September 2018 School of BioSciences University of Melbourne ABSTRACT The rapidly expanding reach of anthropogenic environmental change means that animals must now navigate landscapes comprised largely of modified and degraded habitats. Individuals that correctly perceive habitat quality will be best placed to survive and reproduce in novel environments, but where environmental change outpaces the evolution of behavioural responses, mismatches can arise between cues and the underlying value of habitats. These mismatches can lead individuals to select habitats that offer relatively poor fitness outcomes, creating ecological traps. In environments where ecological traps are likely to occur, data on habitat preferences and fitness consequences can fundamentally change predictions of metapopulation models and increase our understanding of the role that novel habitats play in population persistence, but such data are rarely collected. In this thesis, I first conduct a global meta-analysis to assess the state of knowledge on habitat preference and fitness metrics in animal populations, using wildlife populations associated with aquaculture as a case study. My findings reveal that responses to aquaculture vary widely across taxa and farming systems, ranging from large increases in abundance to near complete displacement. However, the influence of aquaculture on wildlife populations remains poorly understood, as researchers rarely obtain appropriate measures of habitat preference, survival or reproductive success. Accordingly, in subsequent chapters I apply the ecological trap framework to assess marine habitats modified by aquaculture or invasive species.
