初级消费者对富含纤维素的碎屑的低消化率被认为限制了高水平消费者对其的掺入。然而,最近的一项研究表明,在东亚红树林中占主导地位的底栖消费者芝麻蟹Parasesarmabidens具有高纤维素酶活性,使该物种能够有效地消化和同化难降解的碎屑。为了阐明P. bidensas作为促进红树林碎屑进入食物链的营养中间体,对亚热带红树林河口的底栖鱼类的食性进行了研究。胃内容物分析表明,中华绒螯蟹,尤其是中华绒螯蟹P. bidens,作出了很大的贡献,饮食的鱼类检查,包括笛鲷银斑笛鲷和seabreamphilus opagrussivicolus,这两个都是常见的研究地点。碳、氮稳定同位素分析结果表明,红树林碎屑对所有鱼类的营养都有显著贡献,这是由于它们对P的消耗。鬼针草这些结果表明,碎屑营养途径,通过螃蟹具有更大的能力,消化/同化纤维素材料,发挥了不可或缺的一部分,在维持红树林生态系统的食物链结构。
The low digestibility of cellulose-rich detritus in primary consumers has been considered to limit its incorporation by higher level consumers. A recent study revealed, however, that the sesarmid crabParasesarmabidens, which is a dominant benthic consumer in East Asian mangrove forests, possesses high cellulase enzyme activity enabling the species to efficiently digest and assimilate refractory detritus. To elucidate whetherP. bidensacts as a trophic intermediate facilitating the incorporation of mangrove detritus into the food chain, the food habits of benthivorous fishes within a subtropical mangrove estuary were investigated. Stomach content analyses indicated that crabs, especiallyP. bidens, made a large contribution to the diets of the fishes examined, including the snapperLutjanus argentimaculatusand the seabreamAcanthopagrussivicolus, which were both common at the study site. Furthermore, carbon and nitrogen stable isotope analyses revealed that mangrove detritus contributed significantly to all fish species examined, due to their consumption ofP. bidens. These findings suggested that the detrital trophic pathway, via crabs with greater ability to digest/assimilate cellulose materials, plays an integral part in maintaining food chain structures in mangrove ecosystems.
