    Geoghegan, J.L. Di Giallonardo, F. Wille, M. Ortiz-Baez, A.S. Costa, V.A. Ghaly, T. Mifsud, J.C.O. Turnbull, O.M.H. Bellwood, D.R. Williamson, J.E. Holmes, E.C.

    Revealing the determinants of virome composition is central to placing disease emergence in a broader evolutionary context. Fish are the most species-rich group of vertebrates and so provide an ideal model system to study the factors that shape virome compositions and their evolution. We characterized the viromes of nineteen wild-caught species of marine fish using total RNA sequencing (meta-tran…

    Reef Sedimentary Accretion Model (ReefSAM): Understanding coral reef evolution on Holocene time scales using 3D stratigraphic forward modelling
    03 Dec 2019
    University of Sydney
    Barrett, Samuel Jonathan Webster, Jody Michael

    A detailed understanding of the development of coral reefs and their internal structure has important applications for predicting future reef trajectories in light of climate changes, petroleum exploration and reconstructing past environmental changes such as sea level. Numerical computer modelling provides a quantitative means of testing and understanding reef processes and better predicting pas…

    Substrate range and enantioselectivity of epoxidation reactions mediated by the ethene-oxidising Mycobacterium strain NBB4
    13 Dec 2019
    University of Sydney
    Cheung, Samantha McCarl, Victoria Holmes, Andrew Coleman, Nicholas Rutledge, Peter J

    Mycobacterium strain NBB4 is an ethene-oxidizing micro-organism isolated from the estuarine sediments of Botany Bay. In pursuit of new systems for biocatalytic epoxidation, we report the capacity of strain NBB4 to convert a diverse range of alkene substrates to epoxides. A colorimetric assay based on 4-(4- nitrobenzyl)pyridine (NBP) has been developed to allow the rapid characterisation and quant…

    Multimodal learning and inference from visual and remotely sensed data
    05 Nov 2020
    University of Sydney
    Rao, Dushyant De Deuge, Mark Nourani-Vatani, Navid Williams, Stefan Bernard Pizarro, Oscar

    Autonomous vehicles are often tasked to explore unseen environments, aiming to acquire and understand large amounts of visual image data and other sensory information. In such scenarios, remote sensing data may be available a priori, and can help to build a semantic model of the environment and plan future autonomous missions. In this paper, we introduce two multimodal learning algorithms to mode…

    A customary right to fish when fish are sparse: managing conflicting claims between customary rights and environmental rights
    12 Mar 2014
    North-West University
    Feris, Loretta

    This contribution considers the potential conflicts that may arise between customary rights and environmental rights in the face of dwindling marine resources. It sets the scene by reflecting on some of the common themes present in indigenous claims to marine resource by communities who were subjected to colonisation. In doing so it analyses the South African judgment, S v Gongqose Case No. E382/…

    Marine fish parasitology in South Africa: history of discovery and future direction
    14 Sep 2016
    North-West University
    Smit, Nico J. Hadfield, Kerry A.

    Almost 200 years have passed since the first description of a marine fish parasite from South Africa. It is therefore an opportune time to look back, take stock of and reflect on the history of discovery within this field and, based on what we know, propose the future direction for research. The aim of this paper is hence to provide some background information on the growth in our knowledge and u…

    Blood parasite biodiversity of reef-associated fishes of the eastern Caribbean
    14 Sep 2016
    North-West University
    Cook, Courtney A. Sikkel, Paul C. Renoux, Lance P. Smit, Nico J.

    Parasitic micro-organisms can influence multiple ecological processes, from growth, mortality, and behavior, to community structure and trophic interactions, yet are typically ignored components of marine biodiversity. We collected 1298 blood samples from reef fishes off 6 eastern Caribbean islands, representing 27 families, 57 genera and 103 species, in - cluding invasive Indo-Pacific lionfish. …

    Morphological and molecular characterization of a marine fish trypanosome from South Africa, including its development in a leech vector
    28 Nov 2016
    North-West University
    Hayes, Polly M. Lawton, Scott P. Smit, Nico J. Gibson, Wendy C. Davies, Angela J.

    Background Trypanosomes are ubiquitous blood parasites of marine and freshwater fishes, typically transmitted by aquatic leeches. Phylogenetic studies have been dominated by examples derived from freshwater fishes, with few marine representatives. Furthermore, life cycle studies on marine fish trypanosomes have focused on those of the northern hemisphere. In this investigation, we have examined t…

    Contamination status and accumulation characteristics of heavy metals and arsenic in five seabird species from the central Bering Sea
    06 Jun 2017
    North-West University
    Ishii, Chihiro Ikenaka, Yoshinori Nakayama, Shouta M.M. Mizukawa, Hazuki Yohannes, Yared Beyene

    Seabirds are marine top predators and accumulate high levels of metals and metalloids in their tissues. Contamination by metals in the highly productive offshore region has become a matter of public concern. It is home to 80% of the seabird population in the U.S.A., 95% of northern fur seals (Callorhinus ursinus), and major populations of Steller sea lions (Eumetopias jubatus), walruses (Odobenus…

    Bioaccumulation of persistent organic pollutants and their trophic transfer through the food web: human health risks to the rural communities reliant on fish from South Africa's largest floodplain

    North-West University
    Volschenk, C.M. Gerber, R. Ikenaka, Y. Van Vuren, J.H.J. Wepener, V. Smit, N.J.

    The Phongolo River Floodplain (PRF) is South Africa's largest floodplain, unique in being the only large floodplain able to sustain permanent waters throughout the dry season (Kyle, 2002). This highly productive region contains around 90 floodplain associated pans which are rich in biodiversity and is known to be of high ecological and socio-economic importance (Dube et al., 2017). The floodplain…
