摘要

摘要以美国德克萨斯州和俄克拉何马州交界的红河平原鳉鱼(Fundulus zebrinus)为研究对象，对种群内异质性迁移的限制性迁移范式(RMP)进行了检验。在2020年6月至8月期间，我们在5公里的河流段内标记了564条平原鳉鱼，并重新捕获了23条。被捕获个体平均放生17.3 d，平均移动178.2 m/d，最大移动935 m。移动距离和移动速率的分布呈细峰分布，尽管分布是倾斜的，但上游和下游移动的鱼的数量没有差异。我们的研究结果表明，RMP预测了斑马鱼的大尺度运动模式，但与其他眼底动物相比，精细尺度的运动可能更大。

TESTING RESTRICTED MOVEMENT OF PLAINS KILLIFISH (FUNDULUS ZEBRINUS)

Abstract We tested the restricted movement paradigm (RMP) for heterogeneous movement within populations using plains killifish (Fundulus zebrinus) in the Red River on the border of Texas and Oklahoma. During June–August 2020, we marked 564 plains killifish within a 5-km stream segment and recaptured 23 individuals. Recaptured individuals spent on average 17.3 days at large, moved on average 178.2 m/day, and the maximum movement observed was 935 m. Distributions of movement distances and movement rates were leptokurtic, and although distributions were skewed, there was no difference in the number of fish that moved upstream versus downstream. Our results suggest the RMP predicts broad-scale movement patterns of F. zebrinus, but fine-scale movements might be larger in magnitude compared with other Fundulus spp.

期刊介绍： The Southwestern Naturalist (a publication of the Southwestern Association of Naturalists since 1953) is an international journal (published quarterly) that reports original and significant research in any field of natural history. This journal promotes the study of plants and animals (living and fossil) in the multinational region that includes the southwestern United States, Mexico, and Central America. Appropriate submission of manuscripts may come from studies conducted in the countries of focus or in regions outside this area that report significant findings relating to biota occurring in the southwestern United States, Mexico, and Central America. Publication is in English, and manuscripts may be feature articles or notes. Feature articles communicate results of completed scientific investigations, while notes are reserved for short communications (e.g., behavioral observations, range extensions, and other important findings that do not in themselves constitute a comprehensive study). All manuscripts (feature articles and notes) require an abstract in both English and Spanish.
