Abstract

Stalter, R. and Lonard, R.I., 2025. Biology of the threatened Amaranthus pumilus Raf. and Amaranthus greggii S. Watson along coastal beach fronts in North America. Journal of Coastal Research, 41(1), 180–183. Charlotte (North Carolina), ISSN 0749-0208. The cosmopolitan genus Amaranthus is represented by 60 to 75 species in North America. Two species, Amaranthus pumilus and Amaranthus greggii, are restricted to sandy barrier island habitats in the Atlantic and Gulf of Mexico regions of North America. Amaranthus pumilus is a federally and globally threatened species. An opportunistic species that occurs under favorable strand conditions, A. pumilus disappears for extensive periods because of storms, erosion, or human disturbance. Typical habitat sites for A. pumilus are between the high tide mark and lower coppice foredunes and in overwash flats. Amaranthus greggii occurs on sandy barrier islands in the Gulf of Mexico from Louisiana to Texas and from Tamaulipas to the Yucatan peninsula in Mexico. Amaranthus greggii usually occurs above the mean high tide mark in the lee of flotsam to the margins of low foredunes, and it is subject to elimination by storm surges, erosion, and sand coverage.

濒危苋菜的生物学研究。和北美沿海滩涂沿岸的苋菜

斯塔特，R.和罗那德，R., 2025。濒危苋菜的生物学研究。和北美沿海海滨的苋菜（Amaranthus greggii S. Watson）海岸研究，41(1),180-183。Charlotte (North Carolina), ISSN 0749-0208。苋属是世界性的属，在北美有60至75种。两个种，pumilus Amaranthus和greggii Amaranthus，被限制在北美大西洋和墨西哥湾地区的沙屏障岛栖息地。苋菜是一种联邦和全球濒危物种。这是一种机会主义物种，在有利的海滩条件下生长，由于风暴、侵蚀或人为干扰，长时间消失。矮桫椤的典型生境在涨潮点和低丛前丘之间以及冲积平原。红苋菜生长在墨西哥湾从路易斯安那州到德克萨斯州以及从塔毛利帕斯州到墨西哥尤卡坦半岛的沙障岛上。红苋菜通常生长在平均涨潮线以上的漂浮物背风处至低前沙丘边缘，受风暴潮、侵蚀和沙尘覆盖的影响而消失。

期刊介绍： The Journal of Coastal Research (JCR) is one of the leading international journals for coastal studies and processes, and is published bi-monthly by the Coastal Education & Research Foundation [CERF]. By covering the entire field of coastal research, the JCR encompasses all subjects relevant to natural and engineered environments (freshwater, brackish, or marine) and the protection/management of their resources in the vicinity of coastlines of the world. Even though the journal broadly focuses on immediate shoreline zones, the JCR also embraces those coastal environments that either reach some indefinite distance inland or that extend seaward beyond the outer margins of the sublittoral (neritic) zone. The JCR disseminates accurate information to both the public and research specialists around the world on all aspects of coastal issues in an effort to maintain or improve the quality of our planet''s shoreline resources.
