Apart from their overall spatial similarities, puma slides jaguars and pumas avoided using the same location at the same time. This interspecific segregation was detectable over and above the spatial and temporal segregation of individual jaguars.Usamos muestreos intensivos de cámaras-trampa para estudiar las interacciones inter-individuales entre individuos identificados de jaguar ( Panthera onca ) y puma ( Puma concolor ). Datos de ubicaciones temporales de una red de 119 estaciones de trampeo en la cuenca del Cockscomb en Belice proporcionó la primera evidencia de que ambas especies se evitan espacialmente, datos que fueron calibrados con la información de las interacciones intraespecíficas de los jaguares.
El uso de cámaras-trampa tiene ventajas sobre a radio-telemetría para proveer de datos de un conjunto de individuos de una área de estudio. Los 23 jaguares identificados individualmente mostraron un alto grado de sobreposición de sus áreas de actividad, con puma fenty hasta 5 individuos fotografiados en el mismo sitio en un mes. Registramos baja consistencia en las áreas de actividad ("home ranges") en períodos de 3 meses a dos años, con bajos niveles de separación espacial entre individuos pero con un alto flujo de individuos.
Los patrones fenty by puma de actividad nocturna de jaguares y pumas fueron similares. Ambas especies usaron hábitats similares en la cuenca del Cockscomb, indicado por una alta correlación en las tasas de captura por sitio entre las especies. A pesar de estos patrones, los jaguares y pumas evitaron usar el mismo sitio al mismo tiempo. Esta segregación interespecífica fue detectada sobre la segregación espacial y temporal de los individuos de jaguar.Felid social systems have been characterized as solitary with exclusive territories within the sexes ( Sunquist and Sunquist 2002 ).
Seidensticker et al. (1973) suggested that ranges of puma thunder spectra female pumas overlapped in response to the migratory movement of deer between seasons. Among large cats in general, higher densities of females with small and stable ranges are associated with exclusive home ranges of males for dominant individuals, presumably maximizing the number of monitored females. Conversely, lower densities of females with larger and less-stable ranges are associated with overlapping ranges of dominant males, in this case roaming presumably becomes a more effective mate-acquisition strategy ( Sandell 1989 ; Sunquist and Sunquist 2002 ).
These generic patterns are not observed in all field studies. Ranges of males overlap for jaguars, pumas, and leopards in areas where densities of females are high and ranges are overlapping ( Muckenhirn and Eisenberg 1973 ; Núñez et al. 2002 ). In this case, it seems likely that males as well as females are responding to clumped distributions of prey, and dominance hierarchies may be expressed in other ways than exclusive territories. If distribution patterns of males are dictated by the strategy that maximizes the number of mating opportunities for the dominant males ( Sandell 1989 ), subordinates may be puma football boots more focused on finding food and consequently have similar land-tenure strategies as females.
We were therefore able to use the time interval between individual captures at a camera location as an index of presence in an area, with longer intervals between recaptures of the same individual indicating that it had traveled farther away. This format permitted testing interspecific interactions of jaguars with pumas in relation to intraspecific interactions among individual jaguars. Interaction can be interpreted from a frequency distribution through time that is more regular than random, indicating mutual [img]http://www.simplypotterheads.com/images/lose/puma fenty-286dtd.jpg[/img] avoidance, or more aggregated than random, indicating mutual attraction. |
