Abstract

The distribution and composition of zooplankton are influenced by a combination of physico-chemical and biological processes, which in turn have effects on the entire ecosystem. In this study, the influence of environmental factors on zooplankton diversity in mangrove-estuarine coastal waters of Parangipettai, southeast coast of India, was investigated. Water samples were collected for a period of four years from January 2014 to December 2017. Totally, 145 species of zooplankton were recorded with highest belonging to the Arthropoda (63.21%) followed by Protozoa (10.53%), Cnidaria (7.95%), Urochordata (6.03%), Chordata (2.92%), Chaetognatha (2.62%), Mollusca (2.42%), Echinodermata (1.14%), Annelida (1.05%), Brachiopoda (1.01%), Ctenophora (0.57%) and Phoronida (0.55%). The findings of cluster, MDS, Factor analysis and CCA showed that variations in nutrient concentration may significantly alter the biotic community of zooplankton species. Furthermore, site score confirmed the effect of environmental conditions on zooplankton distribution. The result of TRIX showed the dry seasons are classified as scarcely eutrophied whereas wet seasons as moderately eutrophied. The findings of this study offer enhanced insight into how physico-chemical factors interact and vary over space and time, which is crucial for evaluating the effects of climate change on ecosystem services mediated by zooplankton.

印度东南沿海 Parangipettai 沿岸水域浮游动物动态的空间和季节变化

浮游动物的分布和组成受物理化学和生物过程的综合影响，而这些过程又会对整个生态系统产生影响。本研究调查了印度东南海岸 Parangipettai 红树林-河口沿岸水域环境因素对浮游动物多样性的影响。水样采集时间为 2014 年 1 月至 2017 年 12 月，为期四年。共记录到 145 种浮游动物，其中最多的是节肢动物门（63.21%），其次是原生动物门（10.53%）、腔肠动物门（7.95%）、脊索动物门（6.03%）、脊索动物门（2.92%）、腔肠动物门（2.62%）、软体动物门（2.42%）、棘皮动物门（1.14%）、无脊椎动物门（1.05%）、腕足动物门（1.01%）、栉水母纲（0.57%）和棘皮动物门（0.55%）。聚类、MDS、因子分析和 CCA 的结果表明，营养浓度的变化可能会显著改变浮游动物物种的生物群落。此外，地点得分也证实了环境条件对浮游动物分布的影响。TRIX 的结果显示，旱季属于稀疏富营养化，而雨季则属于中度富营养化。本研究的结果有助于深入了解物理化学因素如何相互作用并随时间和空间而变化，这对于评估气候变化对浮游动物所提供的生态系统服务的影响至关重要。

期刊介绍： Ocean & Coastal Management is the leading international journal dedicated to the study of all aspects of ocean and coastal management from the global to local levels. We publish rigorously peer-reviewed manuscripts from all disciplines, and inter-/trans-disciplinary and co-designed research, but all submissions must make clear the relevance to management and/or governance issues relevant to the sustainable development and conservation of oceans and coasts. Comparative studies (from sub-national to trans-national cases, and other management / policy arenas) are encouraged, as are studies that critically assess current management practices and governance approaches. Submissions involving robust analysis, development of theory, and improvement of management practice are especially welcome.
