Ninespine stickleback experimental release
Ninespine stickleback experimental release. The addition of small-bodied ninespine stickleback to fishless thermokarst ponds provided valuable information on their ability to influence invertebrate prey. Through consumption, ninespine stickleback substantially reduced invertebrate biomass during the 6-week experiment.
