Strix Occidentalis Lucida

El tecolote moteado mexicano (Strix occidentalis lucida) es una especie amenazada en Estados Unidos y México, la falta de estudios en todo su ámbito de distribución y la creciente pérdida de hábitat, limita su conservación. El objetivo de este estudio fue estimar la distribución potencial de esta especie en una porción del centro de México. Para ello, se usó el algoritmo Maxent y el software ArcMap utilizando 21 registros de presencia del tecolote, 19 capas bioclimáticas, 4 capas del modelo digital de elevación, una de cobertura, y una de vegetación y uso de suelo. La cobertura, vegetación, elevación, precipitación y temperatura fueron las variables que más explicaron el modelo de distribución potencial. Zacatecas presentó la mayor superficie con muy alta probabilidad de distribución. Maxent parece ser una herramienta útil para definir la distribución de Strix occidentalis lucida; sin embargo, para validar sus resultados, es necesario comprobar en campo la presencia de esta especie en los sitios indicados por este modelo.

Abstract Abstract Barred Owls (Strix varia) have expanded their range throughout the ranges of Northern (Strix occidentalis caurina) and California Spotted Owls (S. o. occidentalis). Field observations have suggested that Barred Owls may be behaviorally dominant to Spotted Owls. Therefore, we conducted a test of behavioral dominance by assessing responsiveness of Spotted Owls to conspecific calls when they were in the simulated presence (i.e., imitation of Barred Owl vocalizations) of a Barred Owl. We hypothesized that Spotted Owls would be less likely to respond to conspecific calls in areas where Barred Owls were common. We used a binary 2 × 2 crossover experimental design to examine male Spotted Owl responses at 10 territories randomly selected within two study areas that differed in abundance of Barred Owls. We also conducted a quasi experiment at four study areas using response data from any Spotted Owl (male or female) detected following exposure to Barred Owl calls. We inferred from the crossover experiment that the simulated presence of a Barred Owl might negatively affect Spotted Owl responsiveness. Both subspecies of Spotted Owl responded less to Spotted Owl calls after exposure to Barred Owl calls, Northern Spotted Owls responded less frequently in areas having higher numbers of Barred Owls, and California Spotted Owls responded less frequently than Northern Spotted Owls overall.
