The spatial, temporal and structural distribution of Antarctic seafloor biodiversity by Jan Jansen, Dipl.-Biol. Under the supervision of Craig R. Johnson Nicole A. Hill Piers K. Dunstan and John McKinlay Submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Quantitative Antarctic Science Institute for Marine and Antarctic Studies (IMAS), University of Tasmania May 2019 In loving memory of my dad, whose passion for adventure, sport and all of nature’s life and diversity inspired so many kids, including me, whose positive and generous attitude touched so many people’s lives, and whose love for the ocean has carried over to me. The spatial, temporal and structural distribution of Antarctic seafloor biodiversity by Jan Jansen Abstract Biodiversity is nature’s most valuable resource. The Southern Ocean contains significant levels of marine biodiversity as a result of its isolated history and a combination of exceptional environmental conditions. However, little is known about the spatial and temporal distribution of biodiversity on the Antarctic continental shelf, hindering informed marine spatial planning, policy development underpinning regulation of human activity, and predicting the response of Antarctic marine ecosystems to environmental change. In this thesis, I provide detailed insight into the spatial and temporal distribution of Antarctic benthic macrofaunal and demersal fish biodiversity. Using data from the George V shelf region in East Antarctica, I address some of the main issues currently hindering understanding of the functioning of the Antarctic ecosystem and the distribution of biodiversity at the seafloor. The focus is on spatial biodiversity prediction with particular consideration given to previously unavailable environmental factors that are integral in determining where species are able to live, and the poor relationships often found between species distributions and other environmental factors. -

The Molecular Evolution of Rhodopsin in Marine-Derived
THE MOLECULAR EVOLUTION OF RHODOPSIN IN MARINE-DERIVED AND OTHER FRESHWATER FISHES by Alexander Van Nynatten A thesis submitted in conformity with the requirements for the degree of Doctor of Philosophy Department of Cell and Systems Biology University of Toronto © Copyright by Alexander Van Nynatten (2019) THE MOLECULAR EVOLUTION OF RHODOPSIN IN MARINE-DERIVED AND OTHER FRESHWATER FISHES A thesis submitted in conformity with the requirements for the degree of Doctor of Philosophy Department of Cell and Systems Biology University of Toronto © Copyright by Alexander Van Nynatten (2019) ABSTRACT Visual system evolution can be influenced by the spectral properties of light available in the environment. Variation in the dim-light specialized visual pigment rhodopsin is thought to result in functional shifts that optimize its sensitivity in relation to ambient spectral environments. Marine and freshwater environments have been shown to be characterized by different spectral properties and might be expected to place the spectral sensitivity of rhodopsin under different selection pressures. In Chapter two, I show that the rate ratio of non- synonymous to synonymous substitutions is significantly elevated in the rhodopsin gene of a South American clade of freshwater anchovies with marine ancestry. This signature of positive selection is not observed in the rhodopsin gene of the marine sister clade or in non-visual genes. ii In Chapter three I functionally characterize the effects of positively selected substitutions occurring on another independent invasion of freshwater made by ancestrally marine croakers. In vitro spectroscopic assays on ancestrally resurrected rhodopsin pigments reveal a red-shift in peak spectral sensitivity along the transitional branch, consistent with the wavelengths of light illuminating freshwater environments. -
Ross Sea As a Marine Protected Area

Weller 2 EXECUTIVE SUMMARY This report provides the scientific basis, validating the results of the CCAMLR Bioregionalization Workshop (2007) as well as the report of ASOC (2010), for identifying the Ross Sea as one of 11 areas deserving close scrutiny for inclusion in a network of marine protected areas. CCAMLR (2007) identified the Ross Sea as an area of high biodiversity on the basis of its high physical heterogeneity; ASOC (2010) compared characteristics of the Ross Sea to areas designated under various international agreements instituted to preserve biodiversity. The CCAMLR (2007) subsequently was endorsed in the joint meeting of CCAMLR's Scientific Committee and the Environmental Protocol's Committee on Environmental Protection (ATCM XXXII-CEP XII, Final Report, 2009). Considered herein is the Ross Sea shelf and slope, which is a smaller portion of the area identified in CCAMLR (2007) as “Ross Sea shelf”. Waters overlying the Ross Sea continental shelf and slope comprise ~2.0% of the Southern Ocean, an area inconsequential in size from a global perspective. However, as shown by this summary of information — amassed from the national research programs especially of Italy, New Zealand, United Kindgom (during the “heroic” era), and United States — the Ross Sea not inconsequential is its biodiversity nor its disproportionate contribution to world populations of many well-known iconic Antarctic species. -
Investigating the Larval/Juvenile Notothenioid Fish Species Assemblage in Mcmurdo Sound, Antarctica Using Phylogenetic Reconstruction
INVESTIGATING THE LARVAL/JUVENILE NOTOTHENIOID FISH SPECIES ASSEMBLAGE IN MCMURDO SOUND, ANTARCTICA USING PHYLOGENETIC RECONSTRUCTION BY KATHERINE R. MURPHY THESIS Submitted in partial fulfillment of the requirements for the degree of Master of Science in Biology with a concentration in Ecology, Ethology, and Evolution in the Graduate College of the University of Illinois at Urbana-Champaign, 2015 Urbana, Illinois Master’s Committee: Professor Chi-Hing Christina Cheng, Director of Research Professor Emeritus Arthur L. DeVries Professor Ken N. Paige ABSTRACT Aim To investigate and identify the species found within the little-known larval and juvenile notothenioid fish assemblage of McMurdo Sound, Antarctica, and to compare this assemblage to the well-studied local adult community. Location McMurdo Sound, Antarctica. Methods We extracted genomic DNA from larval and juvenile notothenioid fishes collected from McMurdo Sound during the austral summer and used mitochondrial ND2 gene sequencing with phylogenetic reconstruction to make definitive species identifications. We then surveyed the current literature to determine the adult notothenioid communities of McMurdo Sound, Terra Nova Bay, and the Ross Sea, and subsequently compared them to the species identified in our larval/juvenile specimens. Results Of our 151 larval and juvenile fishes, 142 specimens or 94.0% represented seven species from family Nototheniidae. Only one specimen was not matched directly to a reference sequence but instead was placed as sister taxon to Pagothenia borchgrevinki with a bootstrap value of 100 and posterior probability of 1.0. The nine non-nototheniid specimens represented the following six ii species: Pogonophryne scotti, Pagetopsis maculatus, Chionodraco myersi, Chionodraco hamatus, Neopagetopsis ionah, and Psilodraco breviceps.
