Other studies show that although poikilotherms are viable at varying temperatures some organisms like the salmon still struggle to survive or succeed as temperature fluctuate (Brett 1971). The fish loses energy and at different stages of their life‚ they have different temperature tolerances that ultimately regulate the fish species overall population and success (Bisson and Davis 1976).

Abstract This study investigated the effects of displaced objects and spatial reorganization on habituation of exploratory behavior. The subjects‚ rats‚ each individually spent 5 minutes in an open field for 6 trials.
