Connell's famous barnacle experiment was initiated to learn more about competitive exclusion and distribution of branacle species. Barnacle species are distributed in distinct zones on the rocky shores of the Atlantic coast. The Chthamalus in upper intertidal zone; is a smaller species and the semibalanus in low intertidal zone which is a larger species. Chthamalus found in the higher physical stress and higher temperatures because the low tide levels causes them to be exposed to the extreme outside environment for longer periods of time than the semibalanus. Additionally barnacles can only feed while submerged and the higher up shore a barnacle is, the less it can feed and grow. The experiment wanted to understand why they lived this way.
<span>The Leeward side of a mountain range is in fact in a rain shadow. A rain shadow is an area of elevation where little to no rain falls, due to precipitation being forced out of passing clouds on the windward side of the mountain. Precipitation condenses as clouds rise over the mountain, and in general it precipitates as it crests over the mountain, leaving no moisture for the leeward side. An example of this is the American west, just west of the Rockies, where little to no rain falls.</span>
