Abundance and Function of Multiple Haemoglobin Isomorphs from Rainbow Trout (Oncorhynchus mykiss)
(University of Waikato, 2011)Haemoglobins perform the vital physiological function of transporting oxygen from the external environment to the tissues. Poikilothermic rainbow trout (Oncorhynchus mykiss = Salmo gairdneri = S. irideus) produce multiple ... -
An assessment of endocrine disrupting potential of a New Zealand pulp and paper mill effluent using rainbow trout Oncorhynchus mykiss and mosquitofish Gambusia affinis
(The University of Waikato, 2001)I examined the effects of a modern mixed thermo-mechanical pulp/bleached kraft (TMP/BK) mill effluent on potential reproductive-endocrine impacts on two fish species, rainbow trout and mosquitofish using a combined approach ... -
Assessing the welfare of captive male giraffes in a bachelor herd using behavioural and hormonal analysis
(The University of Waikato, 2021)As biodiversity continues to decline, zoos play an essential role in ex-situ species conservation. An animal’s ability to feel pain and pleasure drives the need to ensure zoos maintain high animal welfare standards. This ... -
Biological Olfactory Repellents and their Potential to Deter Domestic Dogs (Canis familiaris) from Anticoagulant Rodenticides
(The University of Waikato, 2019)The rapid decline in New Zealand’s terrestrial biodiversity from the impacts of exotic mammalian predators has prompted the nationwide application of anticoagulant rodenticides. However, this application has increased the ... -
Biology of common bully (Gobiomorphus cotidianus) populations in the Tarawera and Rangitaiki Rivers: Reproductive isolation by inland distance or effluent discharges?
(The University of Waikato, 2008)Previous research identified distinct genetic, life-history and reproductive differences between populations of common bully (Gobiomorphus cotidianus) upstream and downstream of a pulp and paper mill outfall on the Tarawera ... -
Characterisation, potential toxicity and fate of storm water run-off from log storage areas of the Port of Tauranga.
(University of Waikato, 2015)Stormwater run-off from industrial sources can impact the receiving environment by the discharge of toxic substances, nutrients, sediments or fresh water (in marine environments). The Port of Tauranga is New Zealand’s ... -
Comparative hypoxia responses and oxygen sensing in galaxiid fishes
(The University of Waikato, 2017)Aquatic ecosystems are inherently characterised by limited oxygen availability and fluctuations in dissolved oxygen concentration, and therefore, environmental hypoxia (i.e. low oxygen conditions) is common. However, in ... -
Does seagrass influence the behavioural and physiological response to flow in juvenile snapper (Pagrus auratus)?
(University of Waikato, 2015)Many juvenile fish species are associated with structural habitats, potentially benefiting them from reduced predation and competition as well as enhanced feeding opportunities. It is also possible that structural habitats ... -
The Effect of a Myostatin Antagonist on the Healing of Burn Wounds in Skin.
(The University of Waikato, 2009)The body's remarkable ability to repair itself from damage is both very useful and extremely complex. The wound healing system is characterised by four overlapping phases: hemostasis, inflammation, proliferation, and ... -
The Effect of Myostatin-antagonist4 on a Severe Muscle Burn Injury
(The University of Waikato, 2009)Myostatin is a growth and differentiation factor which belongs to the transforming growth factor-beta superfamily of genes. Mutations or deletions in the myostatin gene leads to the heavy muscling phenotype seen in various ... -
The Effect of Pax3 Over-expression on Myoblast Function
(The University of Waikato, 2009)The paired-box transcription factor 3 (Pax3), is a powerful myogenic regulatory factor during embryo-myogenesis. The expression of Pax3 is involved in determining somitic cell fate, resulting in the formation of the first ... -
Examination of pulp and paper effluent-hypoxia interactions in fish
(The University of Waikato, 2004)Recent concerns have focused on the adverse effects of low dissolved oxygen (DO) combined with the potential chronic effects of pulp and paper mill effluent exposure on fishes in the Tarawera River, Bay of Plenty, New ... -
Factors controlling common smelt abundance and rainbow trout growth in the Rotorua Lakes, New Zealand
(University of Waikato, 2012)Recreational fisheries are of considerable ecological, economic and cultural importance worldwide, and understanding the factors that influence them is an important goal of fishery managers. The two most important factors ... -
Flow Cytometric Enumeration of the Blood Cells of Rainbow Trout (Oncorhynchus mykiss) and New Zealand Freshwater Crayfish (Paranephrops planifrons)
(The University of Waikato, 2009)The aim of this study was to develop flow cytometric (FC) methods to enumerate rainbow trout (Oncorhynchus mykiss) whole blood cells and New Zealand freshwater crayfish (Paranephrops planifrons) haemocytes as non-lethal ... -
Identifying causes of high pH in lamb meat
(The University of Waikato, 2018)Lamb meat export is a multi-billion-dollar New Zealand industry. Therefore, strategies to maintain and improve quality have immediate commercial benefit. Consumers judge quality by colour, tenderness, and flavour, all of ... -
Inhibition of ERK and GSK3 signalling pathways promotes development and expression of pluripotent markers in bovine blastocysts
(University of Waikato, 2012)Embryo-derived pluripotent stem cells (ePSCs) naturally derive from different founder tissues, namely the early and late epiblast, that vary in their cellular characteristics. Recent evidence in mice suggests these sources ... -
Locating whitebait (Galaxias argenteus) eggs via canine scent detection
(The University of Waikato, 2021)The New Zealand whitebait fishery consists of five species of Galaxiidae fish and constitutes a culturally important commercial and recreational resource for New Zealand. Despite efforts by the Department of Conservation ... -
Native New Zealand fish: lethal and sublethal effects of pentachlorophenol on early and adult life stages
(The University of Waikato, 1998)The sensitivity of four New Zealand freshwater fish species to 99.5% pure pentachlorophenol was studied. For one part of the study, four early life stages of smelt (Retropinna retropinna), inanga (Galaxias maculatus), koaro ... -
Passive in-situ estrogenic potency sampling with DGT-YES
(The University of Waikato, 2019)The purpose of this research was to investigate the presence of bisphenolic plastics and synthetic estrogens in municipal water systems, as well as along the Waikato River. The concentration of these compounds was assessed ... -
Physiological effects of aluminium in relation to diel pH changes on fish and kōura
(The University of Waikato, 2022)Alum (aluminium sulphate, Al₂(SO₄)₃) dosing is used to reduce eutrophication of lakes by sequestering phosphorus and preventing its uptake by phytoplankton for growth. When applied to water at circum-neutral pH, alum forms ...
