Abstract

The Arroyo Chub (Gila orcutti) is a small cyprinid native to coastal drainages of Los Angeles, Orange, Riverside, and San Diego counties. We surveyed the seven drainages historically known to support the species in 2012-2014 and again in 2019 to determine current range and distribution. We compared our results to the most recent species account we could locate (1993). We detected Arroyo Chub in 18 of the 40 streams (45%) and within six of the seven native watersheds in our 2012-2014 surveys, while our 2019 surveys located fish in all of the seven native watersheds. This native species has retreated to the headwaters in most watersheds and the number of populations have declined since the most recent species account. Non-native species, habitat loss, urbanization, water development, flood control, and drought are thought to be the primary causes of this decline.

阿罗约鱼在原生地的现状和分布

阿罗约鱼(Gila orcutti)是一种小型鲤科动物，原产于洛杉矶、奥兰治、河滨和圣地亚哥县的沿海流域。我们在2012-2014年和2019年调查了历史上已知的支持该物种的七个流域，以确定目前的范围和分布。我们将我们的结果与我们能找到的最近的物种记录(1993年)进行了比较。在2012-2014年的调查中，我们在40条河流中的18条(45%)和7个原生流域中的6个中发现了阿罗约鱼，而在2019年的调查中，我们在所有7个原生流域都发现了鱼类。这种本地物种已经退缩到大多数流域的源头，自最近的物种统计以来，种群数量已经下降。非本地物种、栖息地丧失、城市化、水资源开发、洪水控制和干旱被认为是这种下降的主要原因。

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.
