Summary

Story summary

Research at Lake Taupo, New Zealand, investigates nutrient cycles and biodiversity in freshwater lakes.
Strong winds increase food availability for native freshwater mussels, kakahi, by enhancing nutrient upwelling.
Upwelling brings nutrients from the bottom to the lake bed, supporting biodiversity in littoral zones.
Climate change is worsening lake stratification, leading to fewer upwelling events and low oxygen levels.
New molecular tools, such as environmental DNA, aid in monitoring littoral habitats for biodiversity protection.
