Prey Use by Mountain Lions in Southern Texas
We described the diets of mountain lions (Puma concolor) in a prey-rich ecosystem of southern Texas from 1994 to 1997. We estimated white-tailed deer (Odocoileus virginianus), collared peccary (Pecari tajacu), and feral hog (Sus scrofa) densities at 7.7, 4.9, and $6.2\ \text{animals}/\text{km}^{2}$,...

Summary: | We described the diets of mountain lions (Puma concolor) in a prey-rich ecosystem of southern Texas from 1994 to 1997. We estimated white-tailed deer (Odocoileus virginianus), collared peccary (Pecari tajacu), and feral hog (Sus scrofa) densities at 7.7, 4.9, and $6.2\ \text{animals}/\text{km}^{2}$, respectively. Prey use was determined by identifying 75 mountain lions kills and contents of 25 scats. Mountain lions killed white-tailed deer in greater proportion than available, feral hogs less than available, and collared peccaries in proportion to availability. Resource managers in southern Texas should adjust harvest rates of large prey and enhance populations of buffer species to minimize the effects of mountain lion predation. /// Describimos la dieta del puma (Puma concolor) en un sistema ecológico con muchas presas en el sur de Texas desde 1994 hasta 1997. Estimamos densidades del venado (Odocoileus virginianus), pecari (Pecari tajacu), y cerdo salvaje (Sus scrofa) en 7.7, 4.9, y $6.2\ \text{animales}/\text{km}^{2}$ respectivamente. Uso de presa fue determinado por la identificación de 75 animales muertos por el puma, y el contenido de 25 excrementos. Pumas mataron venados en proporciones mas grandes a lo disponible, cerdos salvajes menos de lo disponible, y pecaris en la misma proporción a lo disponible. Gerentes de recursos en el sur de Texas deben ajustar las cosechas de presas grandes y aumentar las poblaciones de especies aisladoras para minimizar los efectos depredadores del puma. |
