Wisconsin's plant communities are responding to shifting disturbance regimes, habitat fragmentation, aerial nitrogen deposition, exotic species invasions, ungulate herbivory, and successional processes. To better understand how plant functional traits mediate species' responses to changing environmental conditions, we collected a large set of functional trait data for vascular plant species occupying Wisconsin forests and grasslands. We used standard protocols to make 76,213 measurements of 34 quantitative traits. These data provide rich information on genome size, physical leaf traits (length, width, circularity, thickness, dry matter content, specific leaf area, etc.), chemical leaf traits (carbon, nitrogen, phosphorus, potassium, calcium, magnesium, ash), life history traits (vegetative and flower heights, seed mass), and traits affecting plant palatability (leaf fiber, fat, and lignin). These trait values derive from replicate measurements on 12+ individuals of each species from multiple sites and 45+ individuals for a selected subset of species. Measurements typically reflect values for individuals although some chemical traits involved composite samples from several individuals at the same site. We also qualitatively characterized each species by plant family, woodiness, functional group, and Raunkiaer lifeform. These data allow us to characterize trait dimensionality, differentiation, and covariation among temperate plant species (e.g., leaf and stem economic syndromes). We can also characterize species' responses to environmental gradients and drivers of ecological change. With survey and resurvey data available from >400 sites in Wisconsin, we can analyze variation in community trait distributions and diversity over time and space. These data therefore allow us to assess how trait divergence vs. convergence affects community assembly and how traits may be related to half-century shifts in the distribution and abundance of these species. The data set can be used for non-commercial purposes. The data set is licensed as follows: CC-By Attribution 4.0 International.

北美东北部维管植物物种的功能性状数据

威斯康星州的植物群落正在应对不断变化的干扰机制、栖息地破碎化、空中氮沉降、外来物种入侵、有蹄类食草和演替过程。为了更好地了解植物功能性状如何介导物种对不断变化的环境条件的反应，我们收集了大量威斯康星州森林和草原维管植物物种的功能性状数据。我们使用标准协议对 34 个数量性状进行了 76,213 次测量。这些数据提供了有关基因组大小、叶物理性状（长度、宽度、圆形度、厚度、干物质含量、比叶面积等）、叶化学性状（碳、氮、磷、钾、钙、镁、灰分）的丰富信息），生活史特征（植物和花的高度，种子质量），以及影响植物适口性的性状（叶纤维、脂肪和木质素）。这些性状值来自对来自多个地点的每个物种的 12 多个个体和选定物种子集的 45 多个个体的重复测量。测量值通常反映个体的值，尽管一些化学特征涉及来自同一地点的几个个体的复合样本。我们还通过植物科、木质、功能组和 Raunkiaer 生命形式对每个物种进行了定性表征。这些数据使我们能够描述温带植物物种之间的性状维度、分化和协变（例如，叶和茎经济综合征）。我们还可以描述物种对环境梯度和生态变化驱动因素的反应。借助威斯康星州 400 多个地点的调查和再调查数据，我们可以分析社区特征分布和多样性随时间和空间的变化。因此，这些数据使我们能够评估性状差异与收敛如何影响群落组装，以及性状如何与这些物种分布和丰度的半个世纪变化有关。该数据集可用于非商业目的。该数据集的许可如下：CC-By Attribution 4.0 International。我们要求用户引用 OSF 数据集和本生态数据论文出版物。该数据集可用于非商业目的。该数据集的许可如下：CC-By Attribution 4.0 International。我们要求用户引用 OSF 数据集和本生态数据论文出版物。该数据集可用于非商业目的。该数据集的许可如下：CC-By Attribution 4.0 International。我们要求用户引用 OSF 数据集和本生态数据论文出版物。
