Physicochemical habitat data and multi-scale occupancy data for spring-associated fishes in Oklahoma streams

Spring-associated fishes occupy thermally unique habitats in groundwater-dominated streams that are often of high quality. However, outside of water temperature, little else is known about the physicochemical habitat requirements for many of these species. With human effects on streams increasing, it is important to conservation and management to characterize spring habitats and the species that occupy them. Our study objective was to determine the physicochemical factors related to occupancy of four spring-associated species in the Arbuckle Uplift and Ozark Highlands ecoregions, Oklahoma USA. We used a hierarchal approach to identify habitat relationships at multiple spatial scales. We collected detection and non-detection data using both snorkeling and seining methods. We examined the physicochemical relationships related to detection and occupancy for four spring-associated fishes. Data were analyzed using occupancy modeling in a Bayesian framework. Our results indicated water depth ...

泉栖鱼类（Spring-associated fishes）栖息于以地下水为主要补给的溪流中，此类溪流的水温环境独具特色，且水质通常优良。然而，除水温之外，学界对多数这类物种所需的理化生境条件仍知之甚少。随着人类活动对溪流的影响日益加剧，明确泉域生境及其栖息物种的特征，对于生境保护与资源管理而言至关重要。本研究旨在明确美国俄克拉荷马州阿巴克尔隆起带与欧扎克高地生态区内，4种泉栖鱼类的栖息分布与理化因子之间的关联。我们采用层级研究方法，在多个空间尺度上解析生境关联特征。我们通过浮潜与围网采样两种方式，获取了物种检出与未检出的调查数据。我们针对4种泉栖鱼类，分析了与物种检出及栖息分布相关的理化因子关联。我们采用贝叶斯框架下的物种占据模型（occupancy modeling）对调查数据开展分析。本研究结果显示，水深……
