Environmental drivers affect the entanglements of humpback whales (Megaptera novaeangliae) and common dolphins (Delphinus delphis) in the gill-nets of the Gold Coast Shark Control Program.
Entanglements primarily occurred during calm sea state conditions, with M.
Waterfalls have unique physical characteristics and harbour specialised macroinvertebrate communities, but have been the subject of few ecological studies.
The present study investigated the trophic structure of waterfall assemblages.
The present study used isotopically enriched copper to measure copper uptake in a marine snail.The fish consumed a diversity range of nutrients, confirming that most are generalists.The results of this study reinforce the importance of riparian forest in the feeding ecology of stream fish.Biomarkers were used to measure the copper-induced stress response.Measuring isotopically enriched copper allowed links to be established among exposure, uptake and response.
