Abstract

Invasive species exert disproportionate impacts in wetlands and pose particular challenges for rare species persisting at small spatial scales. In the urbanized San Francisco Estuary (SFE), which contains 90% of California’s remaining coastal wetlands, invasive and rare species often co-occur. One narrow endemic taxon, the federally listed Suisun thistle (Cirsium hydrophilum var. hydrophilum) is restricted to two or three locations where the invasive perennial pepperweed (Lepidium latifolium) has an increasing presence. Perennial pepperweed has invaded salt, brackish, and freshwater wetlands around the SFE, leading to high management concern. In this study, we investigated how perennial pepperweed may contribute to further rarity of the Suisun thistle, by conducting a removal experiment and surveying soil-plant relationships. Removing pepperweed led to a doubling of native species relative cover and an increase in native species richness by an average of one species per plot, positive effects on Suisun thistle cover, number, and reproductive output, and shifts in soil properties. Combined with survey data inside and outside of pepperweed stands, we conclude that pepperweed competes with Suisun thistle via competition for space, nutrients, and light, interferes with the Suisun thistle’s reproductive success, and alters brackish marsh soil physicochemical characteristics to further favor pepperweed. We recommend local control of pepperweed to prevent further loss of Suisun thistle. Further, the wide range of mechanisms by which this invasion may proceed if unchecked should be considered in other settings where rare or uncommon species are at risk from invaders.

多年生胡椒草(Lepidium latifolium)入侵对濒危水仙蓟(Cirsium hydrophilum var.)
入侵物种对湿地造成了不成比例的影响,并对在小空间范围内持续存在的珍稀物种构成了特别的挑战。在城市化的旧金山河口(SFE),包含了加州 90% 的剩余沿海湿地,入侵物种和珍稀物种经常同时出现。一种狭义的特有分类群,即被联邦列入名录的水苏蓟(Cirsium hydrophilum var. hydrophilum),被限制在两三个地方,而入侵的多年生胡椒草(Lepidium latifolium)在这些地方的存在越来越多。多年生胡椒草已经入侵了盐湖湿地、咸水湿地和淡水湿地,引起了管理部门的高度关注。在这项研究中,我们通过开展移除实验和调查土壤与植物的关系,研究了多年生胡椒草是如何导致穗花蓟进一步稀少的。移除胡椒草后,原生物种相对覆盖度增加了一倍,原生物种丰富度平均每个小区增加了一个物种,对绥顺蓟的覆盖度、数量和繁殖产量产生了积极影响,土壤性质也发生了变化。结合胡椒草丛内外的调查数据,我们得出结论:胡椒草通过争夺空间、养分和光照与穗花蓟竞争,干扰了穗花蓟的繁殖成功,并改变了咸水沼泽土壤的物理化学特征,从而进一步有利于胡椒草的生长。我们建议在当地控制胡椒草,以防止穗花蓟的进一步损失。此外,在稀有或不常见物种面临入侵者风险的其他环境中,也应考虑到如果不加以控制,这种入侵可能会继续发展的各种机制。

期刊介绍: Estuaries and Coasts is the journal of the Coastal and Estuarine Research Federation (CERF). Begun in 1977 as Chesapeake Science, the journal has gradually expanded its scope and circulation. Today, the journal publishes scholarly manuscripts on estuarine and near coastal ecosystems at the interface between the land and the sea where there are tidal fluctuations or sea water is diluted by fresh water. The interface is broadly defined to include estuaries and nearshore coastal waters including lagoons, wetlands, tidal fresh water, shores and beaches, but not the continental shelf. The journal covers research on physical, chemical, geological or biological processes, as well as applications to management of estuaries and coasts. The journal publishes original research findings, reviews and perspectives, techniques, comments, and management applications. Estuaries and Coasts will consider properly carried out studies that present inconclusive findings or document a failed replication of previously published work. Submissions that are primarily descriptive, strongly place-based, or only report on development of models or new methods without detailing their applications fall outside the scope of the journal.
