Maintaining biodiversity is crucial for maximising ecosystem resilience. Despite this, anthropogenic disturbances are driving global biodiversity declines that are heightened in vulnerable ecosystems like coral reefs. Coral reefs are impacted by sedimentation, overfishing and habitat degradation, which impacts biodiversity and therefore the range of functional roles of the reef fish that they support. To evaluate how anthropog...

Animals support a diversity of ecological processes that are linked to the stability, condition and resilience of ecosystems. This means that metrics indexing the diversity of a food web should be linked to the delivery of these ecological processes; yet, how diversity relates to ecological functioning remains unclear in many ecosystems. Coral reefs are reliant on multiple processes to maintain resilience and support ecosystem...

Long-term declines in coastal water quality and sedimentation can affect the restoration success of ecosystems such as seagrass and shellfish reefs. Resnagging coastal seascapes offers a potential alternative restoration method that is not reliant on abiotic conditions and which may enhance degraded landscapes for fish and fisheries. While common in freshwater ecosystems, such interventions are unusual for coastal seascapes de...

Estuaries are crucial feeding, nursery and resting sites for fish but can also be subject to the impacts of severe flooding. The environmental features of estuaries can mediate how they respond to these impacts. For example, the size, configuration, and context of estuarine habitats across seascapes affects the value of patches for fish, and so fish assemblages at sites with a greater habitat extent or closer to the mouth of a...

Disentangling natural and anthropogenic effects on ecosystem condition can uncover bright spots in urban landscapes that are performing above expectations and so are potential sites for conservation or benchmarking, as well as sites performing below expectations that should be the focus of management. In this study, we tested for correlations between metrics indexing ecological condition (focusing on habitat-forming species) a...

Predation is important in maintaining the community structure, functioning and ecological resilience of estuarine seascapes. Understanding how predator community structure, seascape context and habitat condition combine to influence predation is vital in managing estuarine ecosystems. We measured relationships between predator species richness, predator abundance and individual species abundances as well as seascape context an...

Habitat complexity and connectivity can influence the number of species and their diversity across a landscape. For the surf zones of ocean-exposed beaches, globally one of the longest habitat interfaces, the assumed low structural complexity, and apparent homogeneity, of the sandy seafloor habitats predicts low taxonomic and functional diversity. Here, we assessed how the configuration of the seascape and the context of diffe...
