Linkages between productivity and consistent behavioural traits in fish: implications for harvesting, climate impacts, and selective breeding for aquaculture. The extent to which behavior, growth and reproduction are genetically linked in fish populations is unknown, but critical for predicting the impacts of fish harvesting and climate warming, and developing fish stains for aquaculture. If strongly linked, fish harvest will always remove aggressive, large and productive fish, requiring their p ....Linkages between productivity and consistent behavioural traits in fish: implications for harvesting, climate impacts, and selective breeding for aquaculture. The extent to which behavior, growth and reproduction are genetically linked in fish populations is unknown, but critical for predicting the impacts of fish harvesting and climate warming, and developing fish stains for aquaculture. If strongly linked, fish harvest will always remove aggressive, large and productive fish, requiring their protection; in aquaculture, selecting for productive fish will also increase aggression-related injuries. If not strongly linked, we may be able to select for high productivity and low aggression in fish, or high productivity and low metabolism, thus reducing feed costs in aquaculture associated with aggressive behaviour leading to injury and infection, and reduced growth at warmer temperatures.Read moreRead less
Evolution of the unique fauna of the Great Artesian Basin mound springs: the impact of aridification and climate change. The mound springs of the Great Artesian Basin represent one of Australia's most unique environments and are of national biodiversity, cultural and economic significance. Their conservation is a major issue following listing of the springs as a threatened ecological community. As economic productivity in the GAB intensifies, the mound springs are under increasing threat from es ....Evolution of the unique fauna of the Great Artesian Basin mound springs: the impact of aridification and climate change. The mound springs of the Great Artesian Basin represent one of Australia's most unique environments and are of national biodiversity, cultural and economic significance. Their conservation is a major issue following listing of the springs as a threatened ecological community. As economic productivity in the GAB intensifies, the mound springs are under increasing threat from escalating groundwater use. The results of this study on the evolution of two crustacean groups will provide significant biological information for management plans, facilitating conservation of mound springs communities, and helping to understand the impacts of water extraction and climate change on this unique habitat.Read moreRead less
