Invasive plants can cause changes in the structure and function of the ecosystem being invaded. Any changes in ecosystem diversity and community composition will likely alter ecosystem services provided by that ecosystem. However, how these ecosystem services may change is poorly understood. To elucidate how these ecosystem services will change with invasion, we sampled 561 plots undergoing invasion by smooth brome (Bromus inermis) and four other invasive species at a native Rough Fescue prairie located near Saskatoon, Saskatchewan, Canada. Soil and plant surveys were undertaken weekly for 26 weeks between May of 2014 and November of 2014, or the growing season. We measured a suite of ecosystem services, including greenhouse gasses, extracellular enzyme function, forage production, glyphosate degradation and decomposition. Furthermore, soil physical and chemical properties were measured, and soil bacterial and fungal communities were sequenced. This is a large and multifaceted dataset with complex temporal and spatial attributes which can be used to answer numerous questions regarding the functioning of prairie ecosystems and how invasive species will impact that functioning.
入侵植物会导致被入侵生态系统的结构和功能发生变化。任何生态系统多样性和群落组成的变化都可能改变该生态系统提供的生态系统服务。然而，这些生态系统服务可能会发生怎样的变化还不太清楚。为了阐明这些生态系统服务将如何随着入侵而变化，我们在加拿大萨斯喀彻温省萨斯卡通附近的一个原生粗糙羊茅草原上，对 561 个正在被光滑雀麦（Bromus inermis）和其他四种入侵物种入侵的样地进行了采样。我们在 2014 年 5 月至 11 月（生长季节）期间每周进行一次土壤和植物调查，共进行了 26 周。我们测量了一系列生态系统服务，包括温室气体、细胞外酶功能、草料产量、草甘膦降解和分解。此外，还测量了土壤物理和化学性质，并对土壤细菌和真菌群落进行了测序。这是一个具有复杂时空属性的大型和多方面数据集，可以用来回答许多关于草原生态系统功能以及入侵物种将如何影响该功能的问题。
