Abstract
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.
