藤壶可以揭示很多关于其鲸类宿主的生理、健康和空间生态学的信息。在这里，我们研究了温度和水动力因素如何影响Xenobalanus globicipitis的存在，Xenobalanus globicipitis是一种专门附着在鲸类动物身上的假柄藤壶。我们假设温度是一个关键的环境因素（即，水温）和生理因素的影响，其中X. globicipitisp指的是附着时最温暖的皮肤温度，可能是在较冷的沃茨中生存的一种机制。首先，我们展示了宿主物种的空间生态和X的存在之间的全球关系。球结膜炎值得注意的是，X。globicipitisis不存在于四个物种占据沃茨与最低的海表温度（SST）全年，但存在于迁徙物种，可能获得藤壶在沃茨与较高的SST。第二，藤壶附着在普通短吻海豚（Tursiops truncatus）背鳍的位置对应于鳍温度和水动力。虽然体温可能会影响附着在动物身体上的位置，但如前所述，水动力决定了藤壶在成体阶段的附着程度。globicipitisprevalence可能提供了重要的生物指示，生态和生理信息，其主机。由于寄生虫感染有一定的代价，这些结果对变暖海洋中的鲸类动物健康有影响。
Barnacles can reveal much about the physiology, health, and spatial ecology of their cetacean hosts. Here, we examine how temperature and hydrodynamic factors impact presence ofXenobalanus globicipitis, a pseudo‐stalked barnacle that attaches exclusively to cetaceans. We hypothesized that temperature is a key environmental factor (i.e., water temperature) and physiological factor, in thatX. globicipitisprefers the warmest skin temperature for attachment, possibly as a mechanism for survival in colder waters. First, we demonstrate a global relationship between spatial ecology of host species and presence ofX. globicipitis. Notably,X. globicipitisis absent in the four species occupying waters with the lowest sea surface temperature (SST) year‐round, but present in migratory species that likely acquire the barnacle in waters with higher SST. Second, barnacle attachment location on common bottlenose dolphin (Tursiops truncatus) dorsal fins corresponds with fin temperature and hydrodynamics. Although body temperature may influence attachment location on the body of the animal, hydrodynamic forces, as previously proposed, determine how well barnacles can remain attached during the adult stage.X. globicipitisprevalence likely provides important bioindicator, ecological, and physiological information about its host. As parasitic infestation has some cost, these results have implications for cetacean health in warming seas.
