SGS-LTER CO2 Elevation Study: Amount of seedlings germinated from surface soil of Open Top Chamber plots on the Central Plains Experimental Range, Nunn, Colorado, USA 1997 - 2001

This data package was produced by researchers working on the Shortgrass Steppe Long Term Ecological Research (SGS-LTER) Project, administered at Colorado State University. Long-term datasets and background information (proposals, reports, photographs, etc.) on the SGS-LTER project are contained in a comprehensive project collection within the Digital Collections of Colorado (http://digitool.library.colostate.edu/R/?func=collections&collection_id=3429). The data table and associated metadata document, which is generated in Ecological Metadata Language, may be available through other repositories serving the ecological research community and represent components of the larger SGS-LTER project collection.

At the end of the Open Top Chamber study, surface soil was removed from each of the 9 plots, and placed in flats in a greenhouse; mist irrigated frequently, and germinated seedlings were identified by species, to get an idea of the available seed bank after 5 years. There was a great amount of variability; overall there was an increase in seeds in the chambered plots. This research was conducted at the Central Plains Experimental Range, near Nunn, CO; lat.40degrees 40 minutes N; long. 104 degrees 45 minutes W in the shortgrass steppe region of NE Colorado, USA and as a collaboration between SGS-LTER and USDA-ARS researchers.

该数据集由从事科罗拉多州立大学管理的短草草原长期生态研究（SGS-LTER）项目的研究人员所制作。关于SGS-LTER项目的长期数据集及背景信息（提案、报告、照片等）均收录在科罗拉多州数字收藏馆的全面项目集合中（http://digitool.library.colostate.edu/R/?func=collections&collection_id=3429）。数据表及其关联的元数据文档，以生态元语言生成，可能通过服务于生态研究社区的其它数据存储库获得，并代表着更大规模的SGS-LTER项目集合的组成部分。更详细的信息及相关材料可查阅：http://hdl.handle.net/10217/82454。
在开放式顶箱研究结束时，从9个样地中采集地表土壤，并放置在温室的平面上；频繁进行雾化灌溉，通过物种识别幼苗的萌发情况，以了解经过5年后可利用的种子库。研究结果显示出极大的变异性；总体而言，封闭样地中的种子数量有所增加。该研究在位于美国科罗拉多州东北部短草草原的努恩附近的中央平原实验站进行，地理坐标为北纬40度40分钟，西经104度45分钟，并由SGS-LTER与美国农业部农业研究服务局（USDA-ARS）的研究人员合作完成。本数据集中的资源包括：
