以前在美国大西洋海岸的研究表明，沿海前沙丘主要由两种沙丘草，Ammophila breviligulata（美国海滩草）和Uniola paniculata（海燕麦）。从弗吉尼亚州向北，A。breviligulata占优势，而U.圆锥花是弗吉尼亚州南部的优势草。以前的工作表明，这些草影响的形状沿海foredunes在特定的物种的方式，他们对环境压力的反应不同，因此，重要的是要知道哪个物种占主导地位的沙丘系统。由于缺乏全面的调查，这两个物种的范围界限仍然不清楚。在试图确定这些边界，我们进行了文献调查的98项研究，要么说明的范围限制和/或包括基于实地的研究/观察的两个草种。然后，我们制作了一个互动地图，总结了调查的论文和书籍的位置。文献综述表明，目前的南方活动区的限制A。breviligulata是Cape Fear，NC，以及美国的北方范围限制。Paniculata是阿萨提格岛，在马里兰州和弗吉尼亚州的边界。我们的数据表明，美国向北扩张。paniculata，可能与变暖趋势附近观察到的北方范围限制在画家，弗吉尼亚州。相反，关于A. breviligulata仍然没有定论。我们还将我们基于文献的地图与来自全球生物多样性信息设施和iNaturalist研究级众包观测的地理定位记录进行了比较。我们打算为我们的基于文献的地图，以帮助沿海研究人员谁是有兴趣在这两个物种的动态和潜在的范围，以改变气候变化的结果。
Previous work on the US Atlantic coast has generally shown that coastal foredunes are dominated by two dune grass species, Ammophila breviligulata (American beachgrass) and Uniola paniculata (sea oats). From Virginia northward, A. breviligulata dominates, while U. paniculata is the dominant grass south of Virginia. Previous work suggests that these grasses influence the shape of coastal foredunes in species-specific ways, and that they respond differently to environmental stressors; thus, it is important to know which species dominates a given dune system. The range boundaries of these two species remains unclear given the lack of comprehensive surveys. In an attempt to determine these boundaries, we conducted a literature survey of 98 studies that either stated the range limits and/or included field-based studies/observations of the two grass species. We then produced an interactive map that summarizes the locations of the surveyed papers and books. The literature review suggests that the current southern range limit for A. breviligulata is Cape Fear, NC, and the northern range limit for U. paniculata is Assateague Island, on the Maryland and Virginia border. Our data suggest a northward expansion of U. paniculata, possibly associated with warming trends observed near the northern range limit in Painter, VA. In contrast, the data regarding a range shift for A. breviligulata remain inconclusive. We also compare our literature-based map with geolocated records from the Global Biodiversity Information Facility and iNaturalist research grade crowd-sourced observations. We intend for our literature-based map to aid coastal researchers who are interested in the dynamics of these two species and the potential for their ranges to shift as a result of climate change.
