3.0 Effects of temperature on aquatic biota. Temperature has long been recognized as an important environmental factor in both terrestrial and aquatic ecosystems in regard to its pivotal role over biological activity (development, growth and reproduction).emperature reductions to stream environments in winter may result from the loss of insulation of the forest canopy under clear-cut conditions in combination with increased radiant cooling; accelerated freezing may lead to anchor ice formation and minimize interstitial habitat for juvenile fish (Hicks et al.
The marine biome includes all the water that is on the earth's surface. The marine biome covers three fourths of the earth. There are thousnds of animals and plants in the biome. These plants and animals are affected by events in the waters. The earth's climate does not actually affect the marine biome. The water is warm as you get close to the equator and cold as you get closer to the north and south poles. Since water does not heat up or cool down very quickly, there are only small changes in the biome. While the earth's climate does not drastically affect the marine biome, the marine biome does affect climate over land.
