This data set describes the abundance of 50 invertebrate taxa found in intertidal mussel beds along the Atlantic Canadian coast. This information resulted from a regional-scale study that investigated the effects of wave exposure on the richness and composition of invertebrate assemblages from intertidal mussel beds. Abundance data are provided for taxa representing the Annelida, Arthropoda, Bryozoa, Chordata, Cnidaria, Echinodermata, Mollusca, Nematoda, Nemertea, and Platyhelminthes. The data characterize mussel beds from wave-sheltered and wave-exposed locations spanning 315 km of the coast of Nova Scotia. Univariate and multivariate analyses revealed that the compositional structure of these invertebrate assemblages differed markedly depending on wave exposure. Overall, because of its taxonomic diversity, the inclusion of data for basal, intermediate, and top trophic levels, and the coverage of two extremes of environmental stress, this data set could be useful to test broader aspects of ecological theory. Areas of ecology that could advance using this data set are those concerning environmental stress models of community organization, abundance-occupancy relationships, species co-occurrence, species abundance distributions, dominance and rarity, spatial scales of population and community variation, and distribution of functional and phylogenetic diversity. Use of this data set for academic or educational purposes is allowed as long as the data source is properly cited. When used for academic or educational purposes, this data set should be cited using the title of this Data Paper, the names of the authors, the year of publication, and the corresponding volume and article numbers.

加拿大大西洋沿岸潮间带贻贝床无脊椎动物组合的丰富数据

该数据集描述了在加拿大大西洋沿岸的潮间带贻贝床中发现的 50 种无脊椎动物类群的丰度。这一信息来自一项区域规模的研究，该研究调查了波浪暴露对潮间带贻贝床无脊椎动物组合的丰富度和组成的影响。为代表环节动物、节肢动物、苔藓动物、脊索动物、刺胞动物、棘皮动物、软体动物、线虫、线虫和扁形动物的分类群提供了丰富的数据。数据描述了来自新斯科舍省海岸 315 公里的避浪和海浪位置的贻贝床。单变量和多变量分析表明，这些无脊椎动物组合的组成结构因波暴露而显着不同。总体而言，由于其分类多样性，包括基础数据，中级和顶级营养级，以及两个极端环境压力的覆盖范围，该数据集可用于测试生态理论的更广泛方面。可以使用该数据集推进的生态学领域包括群落组织的环境压力模型、丰度-占有关系、物种共存、物种丰度分布、优势和稀有性、种群和群落变异的空间尺度以及功能分布。和系统发育多样性。只要正确引用数据源，就允许将此数据集用于学术或教育目的。当用于学术或教育目的时，应使用本数据论文的标题、作者姓名、出版年份以及相应的卷号和文章编号引用此数据集。
