Shoals in troubled waters: Data

Rising water temperatures across aquatic habitats, in the current global climate change scenario, in freshwater systems, can increase, directly affecting metabolism and food intake in fish species. These can potentially alter their physiological, behavioural and, potentially altering their shoaling properties. In the current study, we examined the effects of future temperatures on metabolism, foraging, and shoaling of tropical fish. Mixed-species shoals, (comprising flying barbs, zebrafish and gambusia) and as well single-species (flying barbs and zebrafish) shoals of flying barbs and zebrafish were conditioned for 45 days to one of the following three kinds of temperature regimes: the Current Temperature Regime (CTR) in which shoals were at 24°C (i.e., the current mean temperature of their habitat), The Predicted Temperature Regime (PTR) which maintained a water temperature of 31°C, (i.e., simulating conditions projected for their habitat in 2100), and The Dynamic Temperature Regime (D...
