摘要

滨海褐藻（Pylaiella littoralis）是一种分布于世界各地的褐色藻类。美国马萨诸塞州纳汉特海滩上有一种自由生活的藻类。在漂浮的藻类中发现了片脚类动物 Gammarus tigrinus。肠道内容物证实 G. tigrinus 食用了 P. littoralis。值得注意的是，培养研究表明，摄入的滨海栉水母能从虎纹蛙产生的粪便颗粒中存活和生长。此外，低效放牧产生的无性碎片也能生长和存活。片脚类动物和滨虫的δ 13C 值平均值分别为-17.4 ‰和-17.7 ‰，这表明虎纹蛙的大部分碳来自滨虫。

Grazing of free-living Pylaiella littoralis by the amphipod Gammarus tigrinus

Pylaiella littoralis is a brown alga with a cosmopolitan distribution. A free-living form of the alga fouls the beaches of Nahant, Massachusetts (USA). The amphipod Gammarus tigrinus is found within the floating drifts of algae. Gut contents confirmed that G. tigrinus consumed P. littoralis. Significantly, culture studies revealed that ingested P. littoralis survives and grows from fecal pellets produced by G. tigrinus. Also, inefficient grazing produced vegetative fragments that grew and survived. δ 13C values for the amphipods and P. littoralis averaged −17.4 ‰ and −17.7 ‰, respectively, suggesting that G. tigrinus acquires most of its carbon from P. littoralis.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
