Vredenburg's experiment that removed trout from Sierra Nevada lakes resulted in a decrease in tadpole population sizes with an increase in adult frog population sizes decrease in adult frog population sizes with an increase in tadpole population sizes decrease in both adult frog and tadpole population sizes increase in both adult frog and tadpole population sizes Which of the following is NOT a direct benefit to females during mating cannibalism of males, spermatophore, long male tail, paternal car Which of the following stage of the malaria life cycle is generated inside of the mosquito? merozoite, sporozoite, hepatocyte, erythrocyte Plasmodium falciparum is the most dangerous species of malaria to humans because it produces the highest number of merozoites in liver cells, it causes liver cells to burst earlier than other species, it can attack three different stages of red blood cells, all of the above are true Which bony fishes evolved the swim bladder?

9. Vredenburg’s experiment was done to show the effect of introduction of non-native fish species in three lakes of Seirra Naveda on the mountain yellow-legged frog (RanaMuscosa)which was native to the lake. In the experiment, it was seen that removing the trout fishes from the lake indeed led to the increase in the population of tadpoles as well as the frog. It was seen that the non-native trouts were actually acting like predators for the tadpoles hence, there population was going down and so do of the frog.
Hence, the correct option is d) increase in both adult frog and tadpole population sizes.
