摘要

珊瑚对温度升高表现出不同的反应,但尚不清楚这是完全由共生体类型还是由宿主的内在特性决定的。本文研究了来自菲律宾西北部Bolinao的三个acroporid物种的ITS2型共生体对温度升高的响应。在26°C(冬季平均温度)和31°C(夏季平均温度)长达48小时的条件下,测量了PSII的最大量子产率(Fv/Fm)。前好客菌比好客菌共生体的Fv/Fm降低幅度更大。然而,与不同acroporids相关或源自不同acroporids的共生体在反应上没有显著差异。因此,虽然这些发现证实了珊瑚宿主可以保护好客的共生体免受温度扰动,但对于本研究中的acroporids,仍然没有证据表明宿主类型赋予共生体或珊瑚全息生物不同的热敏感性。

Comparison of the response of in hospite and ex hospite Symbiodinium to elevated temperature
ABSTRACT Corals exhibit different responses to increasing temperature but it remains unclear whether this is determined exclusively by symbiont type or by intrinsic properties of the host. Here, we investigated the response to elevated temperature of symbionts of the same ITS2 type from three acroporid species from Bolinao, northwestern Philippines. Maximum quantum yield (Fv/Fm) of PSII was measured in symbionts subjected to 26°C (average winter temperature) and 31°C (average summer temperature) for up to 48 hrs. Greater reduction in Fv/Fm was observed for ex hospite than for in hospite symbionts. However, no significant differences in response could be discerned for symbionts associated with or originating from the different acroporids. Thus, while these findings confirm that the coral host can protect in hospite symbionts from temperature perturbations, for the acroporids in this study, there is still no evidence that host type confers differential thermal susceptibility to the symbionts or to the coral holobiont.

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).
