Title | Marine Habitat Restoration |
---|---|
Course | Doctor of Philosophy |
Description | Restoring habitats is a global priority because habitat loss and degradation are major causes of biodiversity loss. Despite billions of dollars spent annually, restoration often fails because animals do not respond as expected or desired to restoration actions. Why this happens, and how we can increase restoration success, are key knowledge gaps.
Is animal behaviour the ‘missing link’? Restoration is based on what humans perceive to be good habitats. Yet, when environments change rapidly (e.g., by restoring habitats), many animals behave in unexpected ways, suggesting a misalignment between human and animal perceptions of habitat. This is very likely in coastal marine ecosystems where measuring animal responses to restoration has not been a priority. Thus, marine habitat restoration might unintentionally create poor-quality habitats that animals mistakenly prefer. Alternatively, animals may avoid restored sites if they cannot detect improved conditions. Without knowing whether restoration creates habitats that animals prefer and that provide suitable conditions for survival and reproduction, we cannot understand why such restoration ‘surprises’ occur or how to mitigate them. This limitation arises because we almost always assess animal responses to restoration using indirect fitness measures (e.g., measures of association) and rarely consider habitat preference.
This PhD project aims to fill this knowledge gap by: 1. Identifying what makes a ‘good’ habitat by comparing direct fitness measures (condition, growth, reproduction and survival) and the resulting population trajectories in restored/unrestored habitats. 2. Determining when animal preferences can limit restoration success through studies of habitat selection. 3. Applying this knowledge to assess current seagrass, kelp forest, and shellfish restoration projects in Western Australia and Victoria. By integrating behavioural ecology with restoration practice, this project will provide major conceptual advances to restoration ecology so that future efforts deliver greater biodiversity benefits by better targeting the elements of habitats that are most important to animals. |
