Abstract
Much is known about movements of female white-tailed deer (Odocoileus virginianus). However, relatively few investigations have been directed toward free-ranging male deer and even fewer have involved mature (≥4 years old) males. Our objectives were to characterize utilization distributions and site fidelity, and to evaluate the subdominant-dominant-floater model using an extensive radiotelemetry dataset collected from male deer ≥1.5 years old in southern Texas. We generated home ranges and core areas of 96 males from 16,696 location estimates collected during January 1993–June 1995. Annual home-range size did not differ among age categories. Males maintained smaller home ranges during spring than during other seasons and old males (≥7 years old) displayed smaller seasonal home ranges than young or mature males. Deer exhibited greater fidelity to home range during summer than during spring, prerut, and rut seasons. We detected limited evidence supporting the subdominant-dominant-floater model. Th... Resumen Existe un amplio conocimiento sobre los patrones de movimiento de las hembras de venado de cola blanca (Odocoileus virginianus). Sin embargo, pocas investigaciones se han enfocado en estudiar a venados machos silvestres y menos aún a machos maduros (≥4 años). Nuestros objetivos fueron caracterizar las distribuciones de uso y fidelidad al sitio, y evaluar el modelo subdominante-dominante-flotante utilizando una extensa base de datos de telemetría de venados machos ≥1.5 años de edad en el sur de Texas. Generamos ámbitos hogareños y áreas núcleo para 96 machos de 16,696 ubicaciones estimadas colectadas entre enero de 1993 y junio de 1995. El tamaño del ámbito hogareño anual entre las categorías de edad no fue diferente. Los machos mantuvieron ámbitos hogareños más pequeños durante la primavera que en las otras estaciones y los machos viejos (≥7 años) mostraron ámbitos hogareños estacionales más pequeños que los de machos jóvenes o maduros. Los venados mostraron mayor fidelidad al ámbito hogareño dura...Keywords
