摘要

科切拉山谷边缘趾蜥蜴Uma inornata于1980年根据《加州濒危物种法》被列为濒危物种。到那时,蜥蜴的栖息地已经减少了90%,分散在数百名土地所有者的私人领地上,形成了孤立的栖息地岛屿。对于输送沙子和维持蜥蜴沙丘栖息地至关重要的生态系统过程已经受到影响。尽管在这种条件下保护栖息地很有挑战性,但这种蜥蜴的种群仍然分布在40年前发现它的大部分地区。年度监测旨在通过量化潜在威胁和压力源的影响,并将适应性管理行动集中在最需要的地方,来评估这些人群的持续生存能力。在这里,我们展示了基于假设的监测是如何确定需要入侵植物控制和沙走廊管理来维持蜥蜴种群的特定位置的。通过在驱动或抑制种群增长的环境变量的背景下监测蜥蜴密度,这种监测方法可以告知是否、何时、何地需要管理行动。

Forty years later: monitoring and status of the endangered Coachella Valley fringe-toed lizard
The Coachella Valley fringe-toed lizard, Uma inornata, was listed as endangered under the California Endangered Species Act in 1980. By that time, the lizard’s habitat was already reduced by 90%, fragmented into isolated habitat islands on private property among hundreds of landowners. Ecosystem processes that are essential for delivering sand and maintaining the lizard’s sand dune habitat were already compromised. As challenging as it was to protect its habitat under these conditions, populations of this lizard still occur across much of the area where it was found forty years ago. Annual monitoring was designed to assess the ongoing viability of these populations by quantifying the effects of potential threats and stressors and focusing adaptive management actions where they are most needed. Here we demonstrate how hypothesis-based monitoring identified specific locations where invasive plant control and sand corridor management were needed to maintain the lizard’s populations. By monitoring lizard densities within the context of environmental variables that either drive or inhibit population growth, this monitoring approach informs if, when, and where management actions are needed.

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
