LONG DISPERSAL DISTANCES OF THREE MALE BOBCATS IN TEXAS
Abstract Dispersal distance of bobcats (Lynx rufus) can be affected by many factors: age and sex, bobcat density, prey abundance, and landscape permeability. Female offspring typically remain near their natal range, whereas males travel farther distances. Studies report dispersal distances between 10 and 85 km, with distances ≥80 km being rare. We report dispersal distances of two male bobcats in the Southern High Plains of Texas, and one male bobcat from the Rio Grande Plains of South Texas. The two male bobcats of Southern High Plains traveled 63 and 133 km and the male bobcat of Rio Grande Plains traveled 100 km. Severe droughts occurred in both regions during dispersal, which may have influenced distance traveled. In all cases, it is likely that nearby available territories were occupied by older resident bobcats, thus eliciting the need for longer-distanced dispersal to secure a permanent home range. Resumen La distancia de dispersión de gatos montés (Lynx rufus) puede ser afectada por muchos factores: la edad y el sexo, la abundancia de los gatos montés, la abundancia de presa y la permeabilidad del paisaje. Las crías hembras típicamente se quedan cerca de su rango de nacimiento, mientras que los machos viajan distancias más lejanas. Estudios han reportado distancias de dispersión entre 10 y 85 km, con distancias ≥ 80 km siendo raras. Reportamos distancias de dispersión de dos gatos montés machos en los Southern High Plains de Texas, y otro gato montés macho del Rio Grande Plains of South Texas. Los dos gatos montés machos de Southern High Plains viajaron 63 km y 133 km, y el otro gato montés macho de Rio Grande Plains viajó 100 km. Durante la dispersión hubo sequías severas en ambas regiones que pueden haber influido en la distancia recorrida. En todos los casos, es muy posible que territorios más cercanos estaban ocupados por otros gatos montés más viejos y residentes, suscitando la necesidad de viajar distancias más lejanas para asegurar un rango de hogar permanente.
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.
