摘要

摘要: 海草床是海岸带最富生产力的生态系统之一，支撑着各种各样的伴生生物。热带的印度和太平洋地区被认为拥有海草植物种类多样性最高，且分布面积最广，然而，这个区域的海草床大型底栖生物我们知之甚少。为了填补认知的空白，我们在该区域开展了一项生态调查，旨在描述该区热带海草床大型底栖生物的丰度和多样性，以及确定大型底栖生物丰度、物种丰富度和群落结构是否明显存在断面内的站间变化和样地间变化。2014年5月和2015年10月我们分别在北苏拉威西省东海岸和西海岸开展野外工作，使用柱状取样器采集海草床大型底栖生物样品。所得样品共计鉴定14大类149种底栖生物，种类最为丰富的类别为多毛类（56种，占26%的总个体数），十足类（20种，占9%的总个体数）和端足类（18种，占35%的总个体数）。东、西海岸海草床大型底栖生物表现出不同的空间分布模式。在东海岸，同一断面的大型底栖生物和端足类的丰度存在显著的站间差异；而在西海岸，大型底栖生物和多毛类的种类丰富度和丰度都表现出明显的站间变化，这可能归结于同一断面底质不均所造成。单因素ANOSIM以及MDS排序表明了北苏拉威西省东海岸和西海岸海草床大型底栖生物群落结构存在显著不同，正好对应于将海草床分成两大类型的栖息地，即西海岸的红树林-海草床-珊瑚连续体和东海岸的海草床-珊瑚连续体。与在热带海区开展的其他研究相比，本研究的大型底栖生物丰度和多样性处于中等水平。东、西海岸海草床大型底栖生物群落存在显著区别，其原因可能源于多方面，包括了沉积物模式，海草床结构和时间变化。

Abstract: Seagrasses are one of the most productive ecosystems in coastal areas and support a wide variety of associated fauna. The tropical Indo-Pacific region is considered to have the highest diversity of seagrass plant species and the largest distribution areas of seagrass, yet the seagrass macrofauna in this region are poorly understood. To help fill this gap in our knowledge, an ecological survey was conducted to describe the abundance and diversity of benthic macrofauna from tropical seagrass beds and to determine between-station variations within a transect and between-site variations in macrofaunal abundance, taxa richness and community structure. Benthic macrofaunal samples associated with seagrass beds were collected with a core sampler on the east coast of North Sulawesi in May 2014 and on the west coast in October 2015. A total of 149 species from 14 higher taxa was collected. The most species-rich groups were polychaetes (56 species, 26% of total individual numbers), decapods (20 species, 9% of total numbers) and amphipods (18 species, 35% of total numbers). Between-station variations within a transect displayed different patterns between the east coast and the west coast. On the east coast, there were marked variations in abundance between stations within a transect for the macrofauna and amphipod assemblages. Both taxa richness and abundance varied with station for the macrofauna and polychaete assemblages on the west coast, resulting from the heterogeneity of the substrate along a transect. One-way ANOSIM together with MDS ordination indicated that macrofaunal community structure in seagrasses differed significantly between the east coast and the west coast, corresponding with the division of seagrasses into two broad categories of habitats, i.e., mangrove-seagrass-reef continuum and seagrass-reef continuum. Compared with other studies in tropical areas, the abundance and diversity of benthic macrofauna in the present study were moderate. The reason for the two markedly distinct macrofaunal communities might be attributed to multiple factors, including sediment pattern, seagrass structure and temporal changes.
