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.

水理化参数对西非水鸟时空活动变化的影响

水的物理化学参数作为非生物因素的变化影响生活在其中的生物体的时空分布。本研究旨在确定贝宁拉姆萨尔湿地1018湿地物理化学特性对鹭科时空变化的影响。为了实现这一目标，从 2015 年 1 月到 2015 年 1 月至 2015 年，使用横断面计数技术和持续 15-30 分钟的固定计数，对 Nokoué 湖、Sô 河、波多诺伏泻湖、Ouémé 河和古泻湖等不同地点的鹭科物种进行每月一次计数。 2016 年 12 月。鸟类计数期间，在每个地点的三个站点测量了水的理化参数。每月记录的 12 个物种中有 5 个受到 水理化参数的显着影响 ( p < 0.05)。随后发现 pH 值影响鹭科空间变化。此类信息与拉姆萨尔湿地 1018 的管理相关，该湿地每年都有来自古北极（欧亚大陆）的迁徙水鸟物种。
