Abstract

ABSTRACT   Differences in the stress experience of sessile organisms across the intertidal zone can differentially influence phenotype. For example, Balanus glandula barnacles from the low intertidal zone have higher lactate levels, greater lactate dehydrogenase (LDH) activity and reduced cirral activity compared to conspecifics from the high intertidal zone. We tested the hypothesis that enhanced anaerobic capacity in lower intertidal B. glandula results from increased predation and hypoxia-inducing shell closure. To investigate this hypothesis, we compared the density of whelk predators across the intertidal zone, and quantified the behavioral response and LDH activity levels of B. glandula exposed to predators in the lab. We consistently found more predators in the low intertidal zone, although the response of B. glandula to predators was short-term operculum closure (<1hr) which did not result in significant differences in LDH activity. Thus, increased predation is not the cause of high anaerobic capacity in lower intertidal B. glandula.
捕食者对橡实藤壶(Balanus glandula)行为和厌氧能力的影响
跨潮间带的无根生物的应激经历的差异可以不同地影响表型。例如,与来自高潮间带的同类相比,来自低潮间带的Balanus glandula藤壶具有更高的乳酸水平,更高的乳酸脱氢酶(LDH)活性和更低的环状生物活性。我们测试了低潮间带B. glandula厌氧能力增强的假设,这是由于捕食增加和缺氧诱导的壳闭合所致。为了验证这一假设,我们比较了整个潮间带海螺捕食者的密度,并在实验室中量化了暴露于捕食者的腺芽螺的行为反应和LDH活性水平。我们一致发现低潮间带的捕食者更多,尽管腺芽胞杆菌对捕食者的反应是短期闭盖(<1hr),这并没有导致LDH活性的显著差异。因此,增加的捕食不是低潮间带腺芽胞杆菌高厌氧能力的原因。

期刊介绍: Marine and Freshwater Behaviour and Physiology is devoted to the publication of papers covering field and laboratory research into all aspects of the behaviour and physiology of all marine and freshwater animals within the contexts of ecology, evolution and conservation. As the living resources of the world’s oceans, rivers and lakes are attracting increasing attention as food sources for humans and for their role in global ecology, the journal will also publish the results of research in the areas of fisheries biology and technology where the behaviour and physiology described have clear links to the contexts mentioned above. The journal will accept for publication Research Articles, Reviews, Rapid Communications and Technical Notes (see Instructions for authors for details). In addition, Editorials, Opinions and Book Reviews (invited and suggested) will also occasionally be published. Suggestions to the Editor-In-Chief for Special Issues are encouraged and will be considered on an ad hoc basis. With the goal of supporting early career researchers, the journal particularly invites submissions from graduate students and post-doctoral researchers. In addition to recognising the time constraints and logistical limitations their research often faces, and their particular need for a prompt review process, accepted articles by such researchers will be given prominence within the journal (see Instructions for authors for details).
