Warming can shift freshwater crustaceans to a 'greener' diet

A new study published in *Limnology and Oceanography Letters* investigates how rising temperatures affect the feeding behavior of the invasive freshwater crustacean *Limnomysis benedeni*. Researchers conducted controlled experiments where mysids were presented with various prey types—microalgae and zooplankton—at three temperature levels (16°C, 23°C, and 30°C). The results showed that as water temperatures increased, the mysids shifted their diets toward herbivory, consuming more algae and less animal prey. This dietary change appears to be influenced by both reduced consumption of zooplankton and increased algal intake, especially when larger zooplankton like *Daphnia magna* were present. Importantly, total carbon intake did not rise significantly with warming, suggesting the shift was about reallocating resources rather than increasing overall consumption. The study highlights potential ecological consequences, noting that such changes could alter the role of invasive species in freshwater food webs, possibly shifting them from predators to competitors. The research underscores the need to understand how climate change influences feeding behaviors of invasive species, which could
