Abstract:
The Galaxiidae is a Southern Hemisphere family of freshwater fish, considered to be of Gondwanan origin based on the current distribution of species in New Zealand, Australia (including Tasmania), New Caledonia, Africa, South America, and on some associated and subantarctic islands. The fossil record of galaxiids is extremely sparse and geographically restricted. The only galaxiid fossils currently known come from several Miocene lakes in southern New Zealand. They include more than 100 articulated fishes, some remarkably preserving soft parts such as eyes and skin, skulls and jaw components, and more than 200 isolated otoliths. Common coprolites and in situ preserved gut content at one site (Foulden Maar) indicate the different diets of larvae and adult fish. These discoveries reveal a diverse Galaxias fauna, the presence of lake-locked populations, ontogenetic diet shifts, and representatives of several non-migratory Galaxias lineages associated with inland streams and lakes. There are at least six Galaxias species based on macrofossils and six separate otolith-based species from varied volcanic and regional lacustrine environments. This diversity points to southern New Zealand as a centre of biodiversity and speciation in Galaxiidae in the early to late Miocene.

Abstract:
Life-history traits are among the most important factors affecting population abundance and genetic diversity of species. Here, we analysed the genetic patterns of two Galaxias species with different life-history traits to investigate how these biological differences impacted their evolution in the Valdivia River basin, Southern Chile. We analysed mitochondrial DNA (mtDNA) sequences from 225 individuals of Galaxias maculatus and 136 of G. platei to compare patterns of genetic diversity, structure and demographic growth across the basin. Galaxias maculatus presented higher genetic diversity and higher genetic structure than G. platei . Demographic analyses showed G. maculatus kept a higher population size over time, with a signal of demographic expansion in the last 250 kyr. Whereas Galaxias platei , exhibited lower, but constant population size over time. Furthermore, haplotype networks revealed higher lineage diversity in G. maculatus with a tendency to occupy different areas of the basin. Coalescent simulations ruled out that genetic differences between species could be explained by stochastic processes (genetic drift), suggesting species-specific biological differences as responsible for the observed genetic differences. We discuss how differences in life-history traits and past glaciations interact to shape the evolutionary history of the two Galaxias species.

Abstract:
Free-living species often receive greater conservation attention than the parasites they support, with parasite conservation often being hindered by a lack of parasite biodiversity knowledge. This study aimed to determine the current state of knowledge regarding parasites of the Southern Hemisphere freshwater fish family Galaxiidae, in order to identify knowledge gaps to focus future research attention. Specifically, we assessed how galaxiid–parasite knowledge differs among geographic regions in relation to research effort (i.e., number of studies or fish individuals examined, extent of tissue examination, taxonomic resolution), in addition to ecological traits known to influence parasite richness. To date, ~50% of galaxiid species have been examined for parasites, though the majority of studies have focused on single parasite taxa rather than assessing the full diversity of macro- and microparasites. The highest number of parasites were observed from Argentinean galaxiids, and studies in all geographic regions were biased towards the highly abundant and most widely distributed galaxiid species, Galaxias maculatus. Parasite diversity generally increased with the number of studies and individual fish examined, however studies which examined parasites from all body tissues could overcome the effects of low study effort. In order to promote further understanding of galaxiid–parasite biodiversity, we provide a series of recommendations, including the use of molecular techniques to verify parasite identity, and highlight the future roles both fish biologists and parasitologists can play.

Abstract:
Galaxias maculatus is a small diadromous fish found in Australia, New Zealand, South America and on some oceanic islands. Two hypotheses have been advanced to explain this widespread, disjunct distribution. McDowall promoted dispersal through the sea of salt-tolerant juveniles but Rosen and others claimed that the distribution reflected the break-up of Gondwana and subsequent drift of the southern continents. Allozyrne electrophoresis of muscle extracts of specimens of Galaxias maculatus from eastern and western Australia, New Zealand and Chile was used to test the hypothesis that populations of G. maculatus from the western Pacific and the eastern Pacific do not differ genetically. FST based on allele frequencies and genotypes was 0.14, suggesting only minor differentiation between eastern and western Pacific populations. Minor differentiation in allele frequency existed at some loci, but no fixation of alternative alleles has occurred. The populations examined appear to be part of the same gene pool, indicating that gene flow via dispersal through the sea occurs today. It is unlikely that South American and Australasian populations would be conspecific if they have exchanged no migrants since the break-up of Gondwana at the end of the Mesozoic.

Abstract:
The Tasmanian Wilderness World Heritage Area encompasses an area of 1.38 million hectares, or approximately 20% of the island state of Tasmania. The World Heritage Area plays a significant role in the conservation of Tasmania's fauna and natural biological processes. The area supports 30 species of terrestrial mammal including three endemic species (91% of total Tasmanian species), 120 species of terrestrial bird including 10 endemic species (76% of state total), 14 species of terrestrial reptile including seven endemic species (67% of state total), seven species of frog including three endemic species (64% of state total), 16 species of freshwater fish including four endemic species (64% of state total), and 68 species of marine fish including one endemic species (14% of state total). A number of vertebrate species are entirely restricted to the World Heritage Area (Moss Froglet, Pedra Branca Skink, Mountain Skink, Pedder Galaxias, Swamp Galaxias and Western Paragalaxias, while the migratory Orange-bellied Parrot breeds only within the World Heritage Area. A number of other species have the majority of their Tasmanian range within the World Heritage Area (Broad-toothed Rat, Ground Parrot, Southern Emu-wren, Tasmanian Tree Frog, Northern Snow Skink, Southern Snow Skink, Bathurst Harbour Skate and the Clarence Galaxias). The World Heritage Area also supports a range of threatened mammal, bird, reptile and fish species. Of the 44 species of introduced vertebrates which have established feral populations in Tasmania, only seven species (16% of state total) have a significant presence within the World Heritage Area and pose a potential threat to the area's integrity. The diversity and endemism of the vertebrate fauna of the World Heritage Area reflects the Gondwanan origins of much of the fauna of western Tasmania, the repeated glaciation of the area during the Pleistocene, and subsequent pulses of speciation among certain taxa.

Abstract:
The gecko Diplodactylus savagei is restricted to the rocky Pilbara and Ashburton regions of Western Australia. Recent collections have enabled a reappraisal of morphological and genetic diversity within the taxon. Analysis of 1200 base pairs of the mtDNA gene ND2 and surrounding tRNA found strong support for three lineages within D. savagei: an eastern clade (which includes the type location of D. savagei from Marble Bar), a southern clade and a north-central clade. The eastern and southern clades did not differ in morphology or dorsal pattern. Although there are several subtle differences in morphological characters between the eastern and southern clades compared to the north-central form, there were clear differences in dorsal pattern with the north-central forms having finer, widely-scattered spots, a pale dorsal border to the loreal stripe and a gradual transition between the dorsal and ventral colouration. We describe the north-central form as a new species, D. galaxias sp. nov., based on the distinctiveness of its colour pattern, subtle morphological differences, mtDNA divergence and maintenance of these differences at the edge of the western Hamersley Range where the north-central and southern clades come into contact.

Abstract:
Coexisting species are interesting from evolutionary and ecological perspectives. Sympatry can provide insights into mechanisms that allow stable long-term coexistence, such as niche partitioning, character displacement, interspecific competition and species boundaries. In New Zealand streams, a flock of closely related non-migratory galaxiid fishes exist throughout eastern South Island (Galaxias vulgaris sensu lato). These fishes are largely parapatric, but recent studies have found streams that contain coexisting populations of two newly discovered galaxiids (Galaxias �southern� and G. gollumoides). In such streams there is a cline from allotopic (sections of streams containing predominantly one species) G. �southern� (lower altitudes) to allotopic G. gollumoides (higher altitudes), with a syntopic (both species) transition section. Such coexistence makes G. �southern� (yet to be formally described) and G. gollumoides ideal for examining the ecology and evolution of sympatric taxa. Very little is known about these two taxa. This thesis aims to detail the morphology, ecology and genetic differentiation between G. �southern� and G. gollumoides. These factors will be used to address separate species status and the possibility of interspecific competition. Data will also be used to examine resource and morphological shifts in either species between syntopy and allotopy, which maybe consistent with character displacement theory. All fish collected for analysis were first classified as G. �southern� or G. gollumoides by eye and by mtDNA. Morphological and ecological (habitat use and diet/isotope enrichment) differentiation between the two species were examined from three sympatric streams (streams containing allotopic and syntopic sites; representing three separate catchments) and four allopatric streams (streams containing only allotopic sites; representing two separate catchments). For sampling purposes, sympatric streams were subdivided into lower (allotopic G. �southern�), mid (syntopic) and upper (allotopic G. gollumoides) sections. We used this sampling regime to test for character displacement (i.e. ecological and morphological shifts between syntopy and allotopy). Diet, stable isotope, genetic structuring and hybridisation (amplified fragment length polymorphisms) were analysed from the three sympatric streams. Artificial stream channels were also used to observe the influence of interspecific competition on resource use over a complete diel cycle. G. �southern� and G. gollumoides were found to be morphologically distinct, differing significantly in 21 of 25 morphological measurements. The two species were also segregated ecologically with G. �southern� preferring shallower water, coarser substrate, and higher water velocity, feeding predominantly on mayflies (Ephemeroptera). In contrast, G. gollumoides preferred deeper water, finer substrate and lower water velocity, feeding predominantly on terrestrial invertebrates. Dietary segregation was also reflected by differences in [delta]�� Carbon and [delta]�⁵ Nitrogen enrichment. Morphological shifts consistent with character displacement were seen in overbite size and mouth size, but neither trait showed consistent statistical differences within and across streams. Ecological shifts were seen in distance to the nearest cover, with G. gollumoides being found further away from cover in syntopy and G. �southern� being found the same distance away from cover in syntopy and allotopy. In artificial stream channels, resource use of both species was not affected by the presence of a congener, but both species used faster water velocities during the night while remaining ecologically distinct. AFLP analysis revealed distinct genotypic clustering between these species with no F1 hybrids. Fine-scale genetic structuring was also observed within both species among streams, and among sites within streams. The minimal effect of a congener on resource use suggests that interspecific competition is not a strong force shaping sympatric populations of Southland galaxiids. This is also reflected by the lack of consistent morphological shifts between allopatry and sympatry. Similarly, character displacement does not seem to be a strong influencing G. �southern� and G. gollumoides. Diel cycles influenced niche expression in both fishes suggesting that abiotic factors may be important in structuring freshwater fish communities in Southland. The fine-scale genetic structuring within both species suggests limited conspecific genetic mixing and movement within streams, which possibly reflects drainage evolution. The absence of F1 hybrids suggests reproductive isolation between G. �southern� and G. gollumoides which may be associated with assortative mating. The present study provides evidence for the separate status of these sympatric fishes under several species concepts. There is conclusive evidence for morphological, ecological and genetic differentiation between sympatric G. �southern� and G. gollumoides, and such segregation maybe associated with long term coexistence in nature. Key words: coexistence, ecology, morphology, genetics, G. �southern�, G. gollumoides.

Abstract:
We present the results of an optical spectroscopic survey of 46 heavily obscured quasar candidates. Objects are selected using their mid-infrared (mid-IR) colours and magnitudes from the Wide-Field Infrared Survey Explorer (WISE) anzd their optical magnitudes from the Sloan Digital Sky Survey. Candidate Active Galactic Nuclei (AGNs) are selected to have mid-IR colours indicative of quasar activity and lie in a region of mid-IR colour space outside previously published X-ray based selection regions. We obtain optical spectra for our sample using the Robert Stobie Spectrograph on the Southern African Large Telescope. 30 objects (65 per cent) have identifiable emission lines, allowing for the determination of spectroscopic redshifts. Other than one object at z similar to 2.6, candidates have moderate redshifts ranging from z = 0.1 to 0.8 with a median of 0.3. 21 (70 per cent) of our objects with identified redshift (46 per cent of the whole sample) are identified as AGNs through common optical diagnostics. We model the spectral energy distributions of our sample and found that all require a strong AGN component, with an average intrinsic AGN fraction at 8 mu m of 0.91. Additionally, the fits require large extinction coefficients with an average E(B - V)(AGN) = 17.8 (average A(V)(AGN) = 53.4). By focusing on the area outside traditional mid-IR photometric cuts, we are able to capture and characterize a population of deeply buried quasars that were previously unattainable through X-ray surveys alone.

Abstract:
Context: Stellar population modelling is a popular technique that has been extensively applied to main sequence galaxies. Yet starburst galaxies and Luminous InfraRed Galaxies (LIRGs) have, so far, not been studied as much using the method. LIRGs in the local universe are known to be highly interacting galaxies with strong star formation in obscured environments. Still, LIRGs also have diversity in terms of morphology and mode and location of star formation. Aim: This thesis investigates the stellar population properties of a group of 52 starbursts and luminous infrared galaxies (LIRGs) in the local universe that forms part of the SUperNovae and starBurst in the InfraReD (SUNBIRD) survey. The galaxies in a distance range of 3.5 < Dl < 280 Mpc and infrared luminosity of 10.30 < LIR < 11.91 L were observed with the Southern African Large Telescope in long-slit spectroscopy mode. Method: The stellar populations of the galaxies are derived by fitting Bruzual & Charlot (2003) templates to the reduced spectra using STARLIGHT software with a Monte Carlo method implemented to recover uncertainties on age, metallicity and extinction. The derived stellar population models are then subtracted from the observed spectra to produce emission spectra from which emission line fluxes are measured. Both integrated spectra and spatially resolved apertures are extracted to be analysed in this work. Results: The light-weighted and mass weighted age of the sample is found to be 160 Myr and 7.2 Gyr respectively. The star formation history of the sample shows a rise of activity in the past ∼ 50 Myr and with a jump of an order of magnitude in the past 3 Myr. Analysis of the stellar metallicity hints at inflow of pristine gas, which decreases the observed metallicity content as well as ignites SF-activity. Analysis of the oxygen abundances shows that while LIRGs and SF galaxies are under abundant, their under-abundance may have previously been over-estimated as compared to main sequence galaxies. The radial age profile of the sample is flat, similar to that of late-type Sd galaxies. Interaction is found to cause a drop in the age of apertures although the post-merging stages shows continued star forming activity in the nuclear region. The stellar metallicity gradient is found to be −0.029 ± 0.018 dex/kpc, comparable to Sb or Sbc galaxies favouring an inside-out formation scenario for the galaxies. As interaction stage increases, both age and metallicity gradients are seen to get flatter, eventually getting slightly positive. The more active interaction stages are HII driven, while isolated and post merging stages shows higher AGN activity. The current work offers an update on the abundances of IR dominated galaxies from the previous work done by Rupke et al. (2008). The formation scenario of our LIRGs in the local universe is shown to be in line with the scenario put forward by Hopkins et al. (2008). Future works with medium resolution spectra acquired during the course of this thesis should allow for detection of gas inflows and better constrain the different ionising mechanisms involved at different interaction stages.

Abstract:
To date, our understanding of the formation and evolution of galaxies attributes a very important role to the neutral hydrogen (HI) gas since it constitutes the reservoir of fuel out of which galaxies form stars. In their evolution, galaxies interact with each other and with their environment, and very often these interactions leave fingerprints in the HI distribution. The extended HI envelopes of galaxies are sensitive tracers of those tidal interactions. In the present study, we map the HI distribution of galaxies in a ~1.5° X 2.5° region of the Virgo cluster using the Karoo Array Telescope (KAT-7) and the Westerbork Synthesis Radio Telescope (WSRT). With a total observing time of ~78 hours with the KAT-7 and 48 hours with the WSRT, we search for low HI column density features in the region. Despite the different observing time and beam size of the two telescopes, we reach similar column density sensitivities of NHI ~1 X 10¹⁸ atoms cm⁻² over 16.5kms⁻¹. With a new approach, we combine the two observations to map both the large and small scale structures. We detect, out to an unprecedented extent, an HI tail of ~60 kpc being stripped off NGC 4424, a peculiar spiral galaxy. The properties of the galaxy, together with the shape of the tail, suggests that NGC 4424 is a post-merger galaxy undergoing a ram pressure stripping as it falls into the centre of the Virgo Cluster along a filamentary structure. We also give the HI parameters of the galaxies detected.

Abstract:
The present International Celestial Reference Frame (ICRF), the ICRF-3 is based on a catalogue of 4536 quasar positions obtained from Very Long Baseline Interferometry (VLBI) radio measurements. This radio frame is crucial for many applications, from measurements of Earth’s orientation in space to spacecraft navigation and measurements of sea-level rise. However, the deficit in ICRF source density in the South and lack of dedicated imaging campaigns in the South, to monitor structural changes, remain a big concern. These ICRF sources can exhibit spatially extended emission structures that can have a significant effect on astrometric VLBI measurements. The Celestial Reference Frame Deep South (CRDS) is a dedicated astrometric VLBI programme to observe Southern ICRF sources on a regular basis. In an effort to improve the situation in the South, these CRDS sessions have recently been optimized for VLBI imaging. In this thesis, I present VLBI images and source structure analysis results for southern ICRF sources observed in four of these CRDS sessions. For some of these sources, I present the very first high-resolution radio images. I also present results from source structure analysis and a corresponding assessment of astrometric quality, and I also present results from efforts to increase the ICRF source density in the South.
