Abstract

Variations in physico-chemical parameters of water as abiotic factors affect the spatio-temporal distributions of the organisms that live in it. The present study aims to determine the influence of physico-chemical properties on Ardeidae spatio-temporal variations in the wetland of Ramsar site 1018 in Benin. To reach this goal, transect enumeration techniques and stationary counts lasting 15–30 min were used to count Ardeidae species once a month at different sites such as Nokoué Lake, Sô River, Porto-Novo Lagoon, Ouémé River and ancient Lagoons from January 2015 to December 2016. Water physico-chemical parameters were measured at three stations per site during the bird counts. Five of the 12 species recorded monthly were significantly influenced (p < 0.05) by water physico-chemical parameters. It was then revealed that pH influenced Ardeidae spatial variation. Such information is relevant to the management of Ramsar Site 1018, which hosts migratory waterbird species from Palearctic (Eurasia) every year.

水体理化参数对西非水鸟（鸻科）活动时空变化的影响

作为非生物因素，水体物理化学参数的变化会影响生活在其中的生物的时空分布。本研究旨在确定物理化学特性对贝宁拉姆萨尔第 1018 号地点湿地海牛科（Ardeidae）时空变化的影响。为实现这一目标，从 2015 年 1 月至 2016 年 12 月，在诺库埃湖、索河、波多诺伏泻湖、韦梅河和古泻湖等不同地点，采用横断面计数技术和持续 15-30 分钟的固定计数，每月计数一次 Ardeidae 种类。在鸟类计数期间，在每个地点的三个站点测量了水理化参数。在每月记录的 12 个物种中，有 5 个物种受到水理化参数的显著影响（p < 0.05）。结果表明，pH 值会影响鸟类的空间变化。这些信息对拉姆萨尔第 1018 号湿地的管理具有重要意义，因为该湿地每年都有来自古北（欧亚大陆）的候鸟迁徙。
