摘    要:头足类作为一种重要的海洋无脊椎动物,在世界海洋生态系统中扮演着非常重要的角色。而目前对其捕食活动和摄食情况的研究不多。稳定同位素作为新型应用技术,被广泛应用于生态系统的研究中。头足类作为捕食者,其体内有大量的碳(C)、氮(N)、氧(O)等稳定同位素,且其硬组织是稳定同位素积累的优良载体,因此通过稳定同位素示踪的方法,分析硬组织各部位稳定同位素含量及其分布,可为了解头足类在海洋生态系统中所处的地位提供手段和方法。根据国内外研究现状,重点分析了耳石、角质额和内壳等硬组织稳定同位素在头足类摄食生态中的应用,并进行了总结和归纳,同时对今后的研究提出了建议。

关 键 词:头足类  稳定同位素  摄食生态  海洋生态系统

Abstract:Cephalopods play the key roles in marine ecosystem as important invertebrate in the ocean. However, little information about its predation and dietary status has been known so far. As a novel applied technology, stable isotope has multiple utility functions with quick inspection and accurate result, so this method is applied in many researches including marine ecosystem. A large proportion of carbon, nitrogen and oxygen are accumulated in the body of cephalopods, which are both predators and food of top predators. The hard structures are the good carrier of the elements for stable isotope. Therefore by means of stable isotope tracing, the content and distribution of stable isotope in every section of hard issue is analyzed to understand the trophic level of cephalopods among the marine organism. In this paper we will give a brief introduction of the application of stable isotope in hard issues of cephalopods (such as statoliths, beaks and inner shell), give a comprehensive understanding of trophic ecology on cephalopods and have a looking in the future.
Keywords:cephalopods  stable isotope  trophic ecology  marine ecosystem
