MACROBENTHOS COMPOSITION FROM THE RIO LAGARTOS HYPERHALINE COASTAL LAGOON SYSTEM, YUCATAN, MEXICO

Incidence data of the macrobenthic species in the Río Lagartos coastal lagoon system, Yucatan, Mexico, was recorded from samplings performed at the end of each climatic season (rainy, northerly winds, and dry season). This 80 km-long lagoon runs parallel to the coast and is hyperhaline through much of its length, with a strong salinity gradient from the head, to the east, where salinity reaches values >100, to the mouth, located at its westernmost side, where salinity reaches seawater values (ca. 34). The macrobenthos community was sampled in 16 stations distributed throughout the lagoon, at depths between ca. 0.5 – 1 m, and two replicates per sample were obtained. Most of the macrobenthic taxa were classified to genus or species level and the incidence of the different taxa is included in this material. Additionally, the salinity values recorded at each station are provided. These data were collected as part of the Salinity Gradient Energy project of the CEMIE-Océano (Mexican Centre for Innovation in Ocean Energy), to increase the knowledge on the biodiversity present in ecosystems with Salinity Gradient Energy potential.

墨西哥尤卡坦半岛里奥拉加托斯海岸潟湖系统的底栖生物种类发生率数据记录于每个气候季节（雨季、北风季和旱季）的末期采样。该长达80公里的潟湖与海岸线平行，在其大部分长度上为过饱和咸水，从源头至东部（盐度达到大于100）至西部的出口处（盐度达到约34的海水值）形成显著的盐度梯度。在潟湖内16个站点对底栖生物群落进行了采样，采样深度介于约0.5至1米之间，每个样本获得两个重复。大多数底栖生物种类被归类至属或种的水平，不同种类的发生率包含在本数据中。此外，每个站点的盐度值也一并提供。这些数据作为CEMIE-Océano（墨西哥海洋能源创新中心）的盐度梯度能源项目的组成部分进行收集，旨在增进对具有盐度梯度能源潜力的生态系统内生物多样性的认识。如需使用完整数据集，建议联系数据提供方。
