Abstract

Abstract Mediterranean wetlands represent a broad variety of natural resources with a huge role in the maintenance of biological diversity. Waterbirds are significant components of this diversity. Among them, the Eurasian Coot Fulica atra is a key species when studying the correlations and interactions between waterbirds and environmental variables, because of its abundance, ease of detection, and relation with some basic aspects of the functioning of wetlands. The present study aimed to analyse the annual and seasonal variation in populations of Eurasian Coot in 31 wetlands in Andalusia, southern Spain, from 2003 to 2008, paying particular attention to correlations with biotic and abiotic variables. The results showed a positive correlation between water depth and coot abundance, while a negative relationship was observed with salinity and no correlation was observed between wetland size and coot abundance. These environmental variables, together with submerged macrophyte coverage, stand out as playing important roles in the use of habitat by coots in Andalusian wetlands.

地中海湿地欧亚白骨顶种群的季节变化与环境变量的关系

地中海湿地代表了种类繁多的自然资源，在维持生物多样性方面发挥着巨大的作用。水鸟是这种多样性的重要组成部分。其中，欧亚白骨顶(Eurasian Coot Fulica atra)是研究水鸟与环境变量相关性和相互作用的关键物种，因为它丰富、容易被发现，并且与湿地功能的一些基本方面有关。本研究旨在分析2003 - 2008年西班牙南部安达卢西亚31个湿地欧亚白骨顶种群的年和季节变化，特别关注与生物和非生物变量的相关性。结果表明，水深与白骨顶丰度呈正相关，与盐度呈负相关，湿地面积与白骨顶丰度无相关性。这些环境变量，连同淹没的大型植物覆盖，在安达卢西亚湿地白骨顶对栖息地的利用中发挥着重要作用。
