Drivers and effects of plastic contamination in aquatic ecosystems
… of macro-litter items (i.e., plastic and fishing gear, rubber, glass, metals, and cloth) led to spatially segregated accumulation hotspots. (Chapter 2). Accumulation hotspots, moreover, can be source of MPs that can eventually contaminate benthic fauna. In Chapter 3, the exposure to MPs …

Predicting salmonid population ecology from individual fish responses to environmental changes: bridging behaviour, conservation and fisheries management.
… stream salmonid populations fail to incorporate fish behaviour and the interactions between fish with their environment and this limits their ability predicting management-relevant salmonid population responses to environmental change. A salmonid individual-based model is parameterised to predict …

Predicting the ecological consequences of river management for a riverine cyprinid fish.
… and habitat models fail to incorporate fish behaviour and the interactions between fish and their environment, thus limiting their ability to predict management-relevant, population responses to environmental change. In order to address these weaknesses, an individual-based model is …

Hydraulic and biological aspects of fish passes for dams
… the efficiency and operation of various types of fish passes for dams. This is achieved through a novel experiment of testing juvenile salmon in a scale model fish-passes with a range of small structures including vertical slots, orifices, weirs and combinations of all three. Direct comparisons of …

Cognitive Abilities in Fish: Biological Predictors and Impact on Reproductive Success
Cognitive Abilities in Fish: Biological Predictors and Impact on Reproductive Success Thesis Abstract Cognitive abilities underpin almost every animal behaviour and allow them to gather, store, process, and use information essential for survival and reproduction. Great variation in cognitive …

Ocean Acidification and Seasonal Temperatures Counter Positive Novel Species Interaction and Warming Effects on Tropicalising Temperate Fish Communities
… extensions. In Australia, over 150 tropical fish species have been observed moving poleward into temperate marine ecosystems but often fail to establish due to hostile conditions (winter temperatures and environmental novelty). However, ocean warming could minimise lethal winter effects on …

Fish Vocalisation: Understanding its biological role from temporal and spatial characteristics
… shrimp have been well described, those of fish are poorly understood. Utilising sound recordings taken from a reef in the Cape Rodney to Okakari Point Marine Reserve, the present study described the vocalisations of two dominant fish vocalisations, the croak and the purr. These sounds …

How marine organisms cope with changing climate
… cellular levels to organismal physiology and behaviour. Such adaptive responses of species will determine their persistence under future ocean warming and acidification conditions. If organisms are capable of maintaining fitness after long-term exposure to a stressor this can be indicative of …

Applied ecology and management of a European barbel Barbus barbus population of a lowland river
… of their biological communities. River fish communities are often used to indicate this altered status due to their ecological, recreational and economic value. In lowland rivers, habitat alterations include impoundments and activities such as channel straightening, impacting aspects of …

Animal personality and the social context: the role of boldness and sociability variation in schooling fish
… their environment. In particular, consistent behavioural variation, known as animal personality, is a substantial driver of a range of important ecological and evolutionary processes. As most animal species are social for at least part of their lives and group living is common, a crucial link …
