Abstract

: Mangrove, terumbu karang, dan padang lamun merupakan ekosistem yang saling berkaitan satu sama lain dan memiliki peran penting bagi komunitas biota di laut sebagai habitat yang menyediakan area pemijahan (spawning ground), area asuhan (nursery ground), dan tempat mencari makan (feeding ground). Beberapa jenis ikan karang hanya hidup pada satu habitat saja, namun beberapa jenis ikan karang yang lain dapat berpindah habitat semasa hidupnya, dari satu area ekosistem ke area yang lain, yang disebut dengan migrasi ontogenetik. Adanya aktivitas migrasi tersebut, menyebabkan terjadinya interaksi antara komunitas ikan karang dengan ekosistem pesisir di sekitarnya. Banyak penelitian telah dilakukan berkaitan dengan interaksi ini, ditinjau dari perpindahan nutrien antar ekosistem dan trofik level komunitas ikan karang, namun belum banyak penelitian yang dilakukan dengan menggunakan pendekatan bentang laut (seascape) dan Sistem Informasi Geografis (SIG). Analisis interaksi antara ekosistem mangrove dan terumbu karang penting dilakukan karena hal tersebut memiliki pengaruh terhadap persebaran ikan dan proses ekologi yang terjadi di dalamnya. Oleh karena itu, penelitian ini dilakukan dengan tujuan untuk dapat hubungan ekosistem mangrove dan terumbu karang berdasarkan komunitas ikan karang di dalamnya. Data komunitas ikan karang didapatkan dari Laporan Reef Health Monitoring (RHM) LIPI pada tahun 2018. Pembuatan peta struktur bentang laut dilakukan dengan menggabungkan Peta Mangrove Indonesia dengan Peta Terumbu Karang menggunakan software QGIS 3.16. Setelahnya, dilakukan ekstraksi seascape metrics, eksplorasi data metrik, uji korelasi dan regresi linier menggunakan software R Studio. Analisis regresi menghasilkan metriks ikan dan seascape metrics pada kandidat model. Hasil diperoleh konektivitas tertinggi di Kepulauan Mentawai adalah pada class area karang terhadap kelimpahan Siganidae dengan nilai persamaan regresi y=4,76-2,86 dan nilai korelasi R = -0,95 serta nilai koefisien determinan R2 = 0,9.

红树林的连通性和生鱼群落的生鱼生长(案例研究:笑岛和伯利兹)
红树林、珊瑚礁和海葵田是一个相互联系的生态系统,是为海洋生物群落提供产卵区、苗圃和觅食场所的栖息地,对海洋生物群落发挥着至关重要的作用。一些种类的珊瑚鱼只生活在一个栖息地,但另一些种类的珊瑚鱼可以在它们的一生中从一个生态系统区域迁移到另一个被称为本体遗传迁徙的区域。这些迁徙活动的存在,导致珊瑚群落与周围沿海生态系统之间的相互作用。鉴于生态系统和珊瑚鱼群落之间的营养转移,已经进行了许多研究,但在采用海运方法(SIG)和地理信息系统(SIG)方面还没有进行多少研究。分析红树林生态系统和珊瑚礁之间的相互作用是很重要的,因为它对鱼类的分布和生态过程有影响。因此,这项研究的目的是利用红树林生态系统和珊瑚礁之间的珊瑚礁联系。珊瑚鱼群组数据来自2018年的珊瑚礁健康监测报告(RHM)。利用QGIS 3.16软件将印尼红树林地图与珊瑚礁地图结合起来,绘制海图。之后,使用R Studio软件进行筛选、度量数据探索、关联测试和线性回归。回归分析会在候选人模型中产生鱼的对称性和远角对称性。在这些岛屿中,学者们取得了最高的联系,将其与Siganidae的含量联系起来,震级为y回归方程=4,76-2,86,相关性值R = - 0.95和导电性系数R2 = 0.9。然而,在别理通水域,最大的连接是对Chaetodontidae储存率的边缘,其相关性为y= 3.23 - 0.14 x,相关性为R = - 0.84,绩效系数为R2 = 0.71。从这项研究得出的结论来看,红树林生态系统和珊瑚礁可能影响了这两个地点大量的珊瑚。红树林、珊瑚采石和海草都是相互关联的生态系统,每一个生态系统都有像产卵地、苗圃和许多海洋生物群集、包括珊瑚礁社区在内的食物。有些珊瑚礁只生活在一个栖息地,有些则在它们的一生中从一个生态系统迁移到另一个生态系统。在它们生命的舞台上的珊瑚礁的运动被称为本体迁移。这种本能行为可以在珊瑚礁鱼和周围的生态系统之间创造出相互作用。许多研究表明,鱼在trophic水平上的生物礁相互作用。但是,有些还是那个小当家》研究用《connectivity seascape接近的地方to examine之间礁鱼surrounding》ecosystems。红树林生态系统和珊瑚礁之间的相互分析影响了珊瑚珊瑚礁的多样性和生态活动。这就是,这个研究aims to analyse红树林interaction》礁鱼》的社区珊瑚礁生态系统,和analyse connectivity价值之间这些二variables,定位》Mentawai和勿里洞。珊瑚礁数据来自reef Health监测器报告在2018年。使用QGIS 3.16软件组合“反乌托邦栖息地地图”进行分析。使用R Studio软件进行分析分析。“回归分析”候选人桌模型中的鱼和远景测量。论点已展示出那个《mangroves之间最高connectivity价值和珊瑚礁到Mentawai是珊瑚珊瑚reefs鱼社区里,礁的课abundance of Siganidae》(y = 4,76-2,86x区域;R = - 95和R2 = 0,9)。Meanwhile,勿里洞最高connectivity价值》是红树林之间的边缘密度abundance of Chaetodontidae (y = 3,23-0,14x》;R = - 84和R2 = 71)。从这项研究中,可以推断出红树林生态系统和珊瑚礁可能会影响珊瑚礁爆裂。

期刊介绍: The Journal of Marine Research publishes peer-reviewed research articles covering a broad array of topics in physical, biological and chemical oceanography. Articles that deal with processes, as well as those that report significant observations, are welcome. In the area of biology, studies involving coupling between ecological and physical processes are preferred over those that report systematics. Authors benefit from thorough reviews of their manuscripts, where an attempt is made to maximize clarity. The time between submission and publication is kept to a minimum; there is no page charge.
