Between may 18 and august 7, 1980, mount saint helens erupted four times. what did the eruptions of mount saint helens teach scientists? a) seeding the slopes was necessary to prevent erosion. b) salvage logging was essential to protecting the arena from fire and insect threats. c) many of the initial pioneering species actually survived the eruptions. d) planting douglas fir trees was essential to recovering the forests.

C). Many of the initial pioneering species actually survived the eruptions.

1980 Mount Saint Helens volcanic eruptions was an example of ecological succession after a catastrophic event. Charlie Crisafulli was a ecologists who arrived at the volcanic site of Mount. Helen along with his colleagues to collect ecological data. He noted the development of ecological relationships across the volcanic landmass. He documented the types, amounts and distribution of surviving organisms, which further took forward the responsibility of colonization in a destructed habitat.

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.
