Urbanisation frequently degrades wetlands via physical modifications, novel stressors and the introduction of pollutants. The health of wetlands can be measured through the use of bioindicators - such as top predators. The research in this thesis quantifies a suite of contaminants and health parameters in snake populations throughout an urban matrix, assesses patterns of bioaccumulation, parasitism and population genomics on snake health, and concludes tiger snakes can be used as an appropriate bioindicator species.

The Broad-Scale Analysis of Metals, Trace Elements, Organochlorine Pesticides and Polycyclic Aromatic Hydrocarbons in Wetlands Along an Urban Gradient, and the Use of a High Trophic Snake as a BioindicatorLettoof, Damian C. ; Bateman, Bill ; Aubret, F.; Gagnon, Marthe Monique (2020)Wetlands and their biodiversity are constantly threatened by contaminant pollution from urbanisation. Despite evidence suggesting that snakes are good bioindicators of environmental health, the bioaccumulation of contaminants ...
Plasma Biochemistry Profiles Of Wild Western Tiger Snakes (Notechis Scutatus Occidentalis) Before and After Six Months of CaptivityLettoof, Damian C. ; Aubret, Fabien; Spilsbury, Francis; Bateman, Bill ; Haberfield, J.; Vos, J.; Gagnon, Marthe Monique (2021)Urban wildlife often suffer poorer health than their counterparts living in more pristine environments due to exposure to anthropogenic stressors such as habitat degradation and environmental contamination. As a result, ...
Evidence and patterns of maternal transfer of metals and trace elements in Western tiger snakes (Notechis scutatus occidentalis) – a pilot studyLettoof, Damian C. ; Van Dyke, J.U.; Gagnon, Marthe Monique (2021)Urban wildlife are regularly exposed to a variety of anthropogenic contaminants that have the potential to bioaccumulate in body tissues. As a consequence, developing embryos and offspring can be at risk from exposure to ...
