Globally, species with small distributions face disproportionate extinction risk, with the impacts of land use change more likely to have catastrophic consequences. Identifying, protecting and managing sites where such species occur is essential for minimising their extinction risk. Yet across Australia, efforts to protect and manage such species' habitats have hitherto been insufficient. Here, we present an example of an analytical and interpretive pathway for the conservation of such species, for a continental-scale case study. We identified 305 Critically Endangered species that have narrow ranges (<20,000 km2), and are distributed in fewer than six discrete patches. We refined existing species' habitat maps with advice from 18 experts via a modified Delphi approach. We assessed how much of each species' habitat is outside protected areas and considered to have agricultural capability, potentially elevating risk of conversion. We identified ∼85,000 km2 of habitat (∼1% of Australia) for these 305 species that must receive protection and management if the nation is going to meet its commitment to halt new extinctions. Approximately half of this habitat is outside the protected area estate, including the entire distribution of 39 species. Approximately 55% of habitat outside of protected areas had at least some agricultural capability. Protecting and managing the habitats of these narrow-range species should be a high priority in state and national conservation policy. Our case study serves as a template for the identification of important habitat for threatened species and could be applied in other regions of the world.

A Computational Fluid Dynamics (Cfd) Based Assessment Of Animal Borne Data Logger Impact, Christopher Pass

School of Engineering, Computing and Mathematics Theses

Animal borne data loggers are powerful tools that provide researchers with valuable insight into the behaviour and ecology of free-ranging marine animals. Despite their usefulness, the addition of a tag inevitably alters the forces acting on a swimming body and can increase the energetic cost of swimming. Computational Fluid Dynamics (CFD) tools offer a powerful means of assessing tag impact and a number of previous works have employed CFD to this end but have typically been based on a range of simplifying assumptions. Chief amongst these simplifications is that animals can be modelled as rigid bodies with a simple tag …

Metamorphosis: An Evaluation Of The Adaptation And Re-Use Potential Of Suburban Housing For Older Homeowners, Michelle Moore

Masters

Ireland’s population is ageing at a rate that is more than twice the EU average. Public policy in Ireland aims to support older persons to age-in-place. Over 80% of older adults in Ireland live in an owner-occupied home, following many decades of public policy promoting home ownership as the tenure of choice. Limited research has been undertaken on the housing adaptation options that could result in privately-owned homes being made more suitable for the evolving needs of the rapidly ageing demographic. This thesis addresses the hypothesis that, with the provision of an appropriate suite of enablers, older homeowners can be …

Meditation Techniques And Their Relationship To Psychotic-Like And Mystical Experiences, Timothy Palmer

School of Psychology Theses

Meditation practice has been associated with benefits but also adverse experiences from anxiety to psychotic-like experiences (PLEs) and even psychosis. The overarching aim was to identify how different types of meditation techniques (varying in bodily focus) differentially relate to psychotic-like experiences and cognitive abilities, including interoceptive awareness, affective awareness and decision-making. For this, I conducted two correlational studies and an intervention study.Different systems have been proposed for classifying meditation techniques. Nash et al’s (2013) approach categorises techniques by goal: Null Directed Methods (NDM), which aim for an “empty” state; Cognitive Directed Methods (CDM), aimed at an enhanced cognitive state; and …

Predictive Perception In Autism, Robert Harlow

School of Psychology Theses

This thesis investigates how predictive perception, motor coordination, and neurotype differences influences social perception in autism. It explores how these mechanisms contribute to social difficulties faced by autistic people, through the lens of the double empathy problem and second-person neuroscience.Chapter 2 examined how spoken intentions and visual evidence guide predictive social perception. Across four experiments, results supported a dual-process model whereby top-down expectations shape early perception but are overridden by visual input once motion begins. This led to the ‘kinematic dominance hypothesis’, suggesting motion cues dominate perception once movement begins due to their higher precision.Chapter 3 used high-resolution active motion …

Understanding Truth And Reconciliations Processes In An Art-Based Community Project Which Addresses Experiences Of Iatrogenic Harm In Mental Health Services, Joseph French

School of Psychology Theses

Research suggests that some service users may have harmful experiences of mental health services. Truth and reconciliations processes have addressed systemic harm in other contexts. However, these are complex and may have positive and negative impacts. Eight interviews were conducted with seven members of a community arts group which uses a truth and reconciliations approach. Members create art to express harmful experiences of the mental health system and display it at exhibitions where mental health professionals are invited to engage with it. The researcher used a constructivist grounded theory informed approach to understand how artists experienced a truth and reconciliations …

“We've Just Kind Of Woven In All These Different Ways Of Keeping Him Close By” A Narrative Analysis Of How Children And Their Surviving Parent Co-Construct Continuing Bonds Following Parental Death, Miriam Summers

School of Psychology Theses

Continuing bonds research has predominantly focused on adults and considered from an individualistic perspective; consequently, little is known about how such bonds may be developed relationally within families. This study aimed to explore how parentally bereaved children and their parent/caregiver co-construct continuing bonds. Eight families were recruited, and parent/caregivers and their children were interviewed together. Narrative analysis explored semantic themes and interactional processes. The findings highlighted that continuing bonds are co-constructed through regular joint remembering, family acts of remembrance, joint connecting through objects and shared interpretations of signs from the deceased. Constructive interactional processes included collaboration, agreement and sharing positive …
