Apart from their overall spatial similarities, puma australia 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 puma shoes sus áreas de actividad, con 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 puma suede flujo de individuos.
Seidensticker et al. (1973) suggested that ranges of 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 puma womens shoes and Sunquist 2002 ).
They found evidence of jaguars and pumas using the same habitat but avoiding each other temporally. Their sample sizes were too small to calibrate interspecific avoidance against intraspecific interactions, which is a prerequisite to inferences about niche separation between species.In this study, we tackled the fundamental issue of small sample sizes in studies of large cats by deploying an extensive network of camera traps to capture timed locations of jaguars and pumas. The unique spot pattern of jaguars allows individual recognition from camera-trap photographs ( Silver et al. 2004 ).
Although recognition of individual pumas may be possible under certain circumstances ( Kelly et al. 2008 ), in the present study individual pumas could not be identified with certainty over the long term because of their plain brown coat pattern ( Harmsen 2006 ).Here we analyze temporal and spatial interactions between a uniquely large sample of individuals to tackle 2 fundamental questions about the function of jaguar movements in resource exploitation: Does spatial overlap of ranges of males depend on puma mens shoes hierarchies of residence? Are temporal interactions of jaguars with pumas distinguishable from conspecific interactions.
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 mens shoes-967raz.jpg[/img] avoidance, or more aggregated than random, indicating mutual attraction. |
