潮间带藤壶Semiba！肛门（Ba/anus）ba！anoides和Chthama！对脆弱类进行了研究，以确定影响潮间带局部地带性的因素是否也有助于地理界限的建立。物理和生物因素影响潮间带分带在新英格兰的Chthalus的北方限制。在斜坡表面Semibalanus死在所有海岸水平高于中潮水平，显然是由于干燥与夏季高温。Chthamus解决发生在所有海岸水平以上的平均潮汐水平，和postsettlement死亡率显然限制Chthama！我们到高海岸的位置，半藤壶的生长和生存受到抑制。半藤壶在克特鲁斯的北方边界以北，不受夏季热死的影响，因此它占据了克特鲁斯在更南边的玉米地避难的区域。Chthalus的北方界限并不是由与作用于Chthalus的寒冷直接相关的因素决定的。相反，北方的界限似乎是由寒冷决定的，这使得占主导地位的竞争者将Chthalus排除在其避难区之外。北方南极限的竞争对手，森米巴！肛门，被排除在高海岸的夏季高温。
The interactions between the intertidal barnacles Semiba!anus (Ba/anus) ba! anoides and Chthama!usfragilis were examined in order to determine whether the factors which influence local zonation in the intertidal also contribute to the estab lishment of geographic limits. Both physical and biotic factors influence intertidal zonation at the northern limit of Chthamalus in New England. On sloping surfaces Semibalanus died at all shore levels higher than mid tide level, apparently as a result ofdesiccation associated with high summer temperatures. Chthamalus settlement occurred at all shore levels above mean tide level, and postsettlement mortality apparently restricts Chthama!us to high shore locations where Semibalanus growth and survival is inhibited. North of the northern limit of Chthamalus, Semibalanus does not suffer summer heat death, so it occupies the zone where Chthamalus would have a refuge from corn petition further south. The northern limit of Chthamalus is set not by factors directly related to cold acting on Chthamalus. Rather the northern limit appears to be set by cold which allows the dominant competitor to exclude Chthamalus from its refuge zone. South of the northern limit the competitor, Semiba!anus, is excluded from the high shore by high summer temperatures.
