A Genetic Investigation Of Anticoagulant Rodenticide Resistance In Mus Musculus Of Western Australia: Implications For Conservation And Biosecurity, Bridget Judith Maria Lucrezia Duncan Jan 2021

A Genetic Investigation Of Anticoagulant Rodenticide Resistance In Mus Musculus Of Western Australia: Implications For Conservation And Biosecurity, Bridget Judith Maria Lucrezia Duncan

Theses : Honours

Human-wildlife interactions have developed since the agricultural revolution that occurred 10,000 years ago, and the expansion of commensal species’ geographical distribution led to conflicts that prompted humans to adopt a wide range of control methods for pest species (Horvitz, Wang, Wan, & Nathan, 2017; Riyahi et al., 2013; Saraswat, Sinha, & Radhakrishna, 2015). The order Rodentia is characterised by a high number of successful invaders, which humans have attempted to manage with the use of anticoagulant rodenticides (ARs) since the 1940s (Capizzi, Bertolino, & Mortelliti, 2014; Ruiz-Suárez et al., 2014). The rise and spread of a genetic mutation that infers …


The Personal Is Political And The Political Can Be Very Bloody Personal : Family Farming In A Deregulated Dairy Industry, Terese Reid Jan 2001

The Personal Is Political And The Political Can Be Very Bloody Personal : Family Farming In A Deregulated Dairy Industry, Terese Reid

Theses : Honours

This qualitative study considers the links between the political ideology that led to the deregulation of the dairy industry in July 2000 and the personal lived experiences of dairy farming families at a grass roots level. The post-deregulation experiences of dairy farming families within the South West region of Western are investigated through an engaged critical ethnographic methodology. A critical analysis of the political policies relating to dairy deregulation, is also incorporated within the study's methodological framework. The underlying aims of critical ethnography are emancipation, empowerment and liberation. The central purpose of this research is to give the daily farming …


The Impact Of Permaculture On The Above-Ground Mesofaunal Communities In The Perth Metropolitan Area, Ruth C. D'Sanges Jan 1997

The Impact Of Permaculture On The Above-Ground Mesofaunal Communities In The Perth Metropolitan Area, Ruth C. D'Sanges

Theses : Honours

Conventional agricultural practices (tillage, extensive application of synthetic fertilisers and biocides) exert substantial disturbance on soil ecosystems, consequently causing severe land degradation through loss of soil organic matter. These practices also place significant pressure on the soil inhabitants. However, permaculture systems practice non-tillage and extensive mulching. These non-tillage practices reduce the amount of perturbation on the litter invertebrates and encourage their abundances. The aims of this study were to describe the above-ground mesofaunal communities in the mulch layer of selected urban permaculture systems in the Perth Metropolitan area. This included determining the faunal abundance and diversity. Four permaculture sites were …


Modelling The Effects Of Rehabilitation And Changed Agricultural Practices In A Saline-Affected Rural Catchment, M. K. Heller Jan 1996

Modelling The Effects Of Rehabilitation And Changed Agricultural Practices In A Saline-Affected Rural Catchment, M. K. Heller

Theses : Honours

The Bremer river catchment, on the South-coast of Western Australia, is typical of most river catchments in this region in that it has been seriously affected by sedimentation, salinisation and eutrophication brought on by the gradual dominance of agricultural land management practices. Vegetated rehabilitation and changed agricultural land management practices (ie minimum / zero tillage) have now been widely adopted throughout the catchment in response to these degradation issues. This study examined the potential impact minimum / zero tillage, vegetated rehabilitation and remnant vegetation could have on both a farm and catchment wide scale. A Geographical Information System was developed …
