摘要

本文报道了生活在南安达曼红树林近带水域的tintinnids与环境之间的相互作用，涉及某些物理化学（温度、盐度、pH和溶解氧）和生物（浮游植物生物量）参数。由于红树林水域近端区受规律的潮汐作用，本文在东北季候风、季风间期和西南季候风期间对tintinnids群落进行了为期一年的研究（2012年9月- 2013年8月）。共记录到18属26种，丰度存在明显的季节和空间差异，西南季候风（19 ~ 59 ind L−1）丰度较高，季风间期（18 ~ 27 ind L−1）丰度次之。典型对应分析（Canonical correspondence analysis， CCA）和Spearman秩相关等统计分析表明，环境变量的影响随季节而变化，温度（r = 0.76-0.90）、盐度（r = 0.90-0.1）和pH （r = 0.90-0.1）是影响南安达曼红树林近端水域tintinnids群落的主要变量。

A Study on Tintinnids (Loricate Ciliates) From the Mangrove Proximal Zone Waters of Sri Vijaya Puram (Port Blair), South Andaman

We report here the interaction between the environment and tintinnids inhabiting in the mangrove proximal zone waters of South Andaman, in relation to certain physicochemical (temperature, salinity, pH, and dissolved oxygen) and biological (Phytoplankton biomass) parameters. As the proximal zone of mangrove waters is subjected to regular tidal effect, tintinnids community was studied for one year (September 2012–August 2013) during the Northeast monsoon, Inter-monsoon, and the Southwest monsoon periods. We recorded a total of 26 species belonging to 18 genera, and the abundance of tintinnids varied seasonally and spatially with higher abundance during the Southwest monsoon (19–59 ind L⁻¹) followed by the Inter-monsoon (18–27 ind L⁻¹). Statistical analysis, such as Canonical correspondence analysis (CCA) and Spearman rank correlation, depicts that the influences of environmental variables varied seasonally, and temperature (r = 0.76–0.90), salinity (r = 0.90–0.1), and pH (r = 0.90–0.1) are the major variables influencing on tintinnids assemblages in the mangrove proximal zone waters of South Andaman.

期刊介绍： Marine Ecology publishes original contributions on the structure and dynamics of marine benthic and pelagic ecosystems, communities and populations, and on the critical links between ecology and the evolution of marine organisms. The journal prioritizes contributions elucidating fundamental aspects of species interaction and adaptation to the environment through integration of information from various organizational levels (molecules to ecosystems) and different disciplines (molecular biology, genetics, biochemistry, physiology, marine biology, natural history, geography, oceanography, palaeontology and modelling) as viewed from an ecological perspective. The journal also focuses on population genetic processes, evolution of life histories, morphological traits and behaviour, historical ecology and biogeography, macro-ecology and seascape ecology, palaeo-ecological reconstruction, and ecological changes due to introduction of new biota, human pressure or environmental change. Most applied marine science, including fisheries biology, aquaculture, natural-products chemistry, toxicology, and local pollution studies lie outside the scope of the journal. Papers should address ecological questions that would be of interest to a worldwide readership of ecologists; papers of mostly local interest, including descriptions of flora and fauna, taxonomic descriptions, and range extensions will not be considered.
