摘要

近年来,柔佛海峡受到大量人为活动的影响,导致环境改变,不可避免地损害了海底大型底栖生物。我们对海峡内的几个关键地点进行了全面评估,以确定大型底栖生物居民以及造成这些地区大型底栖生物组合差异的可能驱动因素。在柔佛海峡的 13 个主要地点使用 Ponar Grab 采集了沉积物。在海峡 13 个地点的沉积物中确定了 730 个大型底栖生物个体和 46 个已知分类群。无脊椎动物 Prionospio(295 个)、Minuspio(95 个)和 Mediomastus(82 个)主要集中在中部区域。软体动物主要分布在美兰邦浅滩地区(Arcualuta,n=66),片脚类动物主要分布在三提河附近海域(Leucothoe,n=26;Gammarus,n=11;Cymadusa,n=9)。PERMANOVA 分析(p<0.05)表明,所有地点的底栖类群组成总体上存在显著差异。BIOENV 分析(r=0.76,p<0.05)表明,水酸度、叶绿素-a、淤泥和总有机碳是影响整个研究区域底栖生物组合的主要因素。PCA 图显示,中部地区的有机碳和淤泥含量较高,这意味着有利于定居多毛目动物的生长。海峡东西两端的水酸度和叶绿素-a 读数较高,这可能直接导致该区域底栖生物群落的多样性较高。中部两个地点(J3=2.97 毫克/升,J4:2.63 毫克/升)的氧气水平较低,表现为以 Sedentaria 多毛目虫为主的区域,但中部另一部分(J5-J9,2.97-0.99 毫克/升)的底栖生物为零。这项研究展示了以大型底栖生物为指示对象进行环境监测的有效性。

The Macrobenthos Diversity and Dominance in Johor Straits, Malaysia
Johor Strait has received massive anthropogenic traffic in recent years, causing environmental alteration and inevitably harming macrobenthos on the seafloor. A comprehensive assessment was done in several key locations within the strait to identify macrobenthic inhabitants and possible driving factors attributing to differences in macrobenthic assemblages in these areas. Sediments were acquired using Ponar Grab in 13 key locations within the Johor Straits. Seven hundred thirty macrobenthic individuals and 46 known taxa were identified in sediments of 13 locations in the strait. Annelids Prionospio (n=295), Minuspio (n=95) and Mediomastus (n=82) were concentrated in the central zone. Molluscs dominated the Merambong Shoals area (Arcualuta, n=66), and amphipods dominated waters off Santi River (Leucothoe, n=26; Gammarus, n=11; Cymadusa, n=9). PERMANOVA analyses (p<0.05) showed significant differences in benthic taxa composition in all locations overall. BIOENV analyses (r=0.76, p<0.05) highlighted water acidity, chlorophyll-a, silts and total organic carbon as the main influences toward benthic assemblages throughout the study area. PCA graph indicated higher organic carbon and silts in the central area, implying favourable conditions for Sedentarian polychaetes to thrive. The east and west ends of the strait exhibited higher readings of water acidity and chlorophyll-a, which may directly contribute to a higher diversity of benthic communities in the areas. Lower oxygen levels in two locations in the central area (J3=2.97 mg/L, J4: 2.63 mg/L) exhibited Sedentaria polychaete-dominated region, but zero benthic organisms in another part of the central area (J5-J9, 2.97–0.99 mg/L). This study showcased the effectiveness of environmental monitoring using macrobenthos as an indicating subject.
