Drought and its consequences on river life

The animals fared badly. 37% of the animals that eat the algae ad detritus were gone, with their biomass down greatly to a meagre 36% of their former glory. And of course this spelt misery for the poor old predators, with their food supply withered on the vine. 78% disappeared along with 88% of their biomass. Drought effectively eroded foodwebs from the top-down. Significant high mortalities for stranded predators were regularly recorded. The biomass recovered slightly from large numbers of chironomid midge larvae exploiting the disturbance in the community. Certain small entrepreneurs were theorised to be capable of taking over temporary niches. Large animals disappeared, in some cases to "drought refugia," more suited to smaller predators
