ÿþWe used extensive camera-trap surveys to new balance mens shoes study interindividual interactions among individually recognizable jaguars ( Panthern onca ) and plain-colored pumas ( Puma concolor ). Timed location data from a network of 119 trap stations in the Cockscomb Basin of Belize provide the 1st evidence of interspecific avoidance calibrated against intraspecific interactions among jaguars. Camera trapping has advantages over radiotelemetry in its potential to provide data on the complete array of individuals within the study area.
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 new balance outlets 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 new balance shoes for men individuos pero con un alto flujo de individuos.
However, the mechanisms of sympatric coexistence of jaguars and pumas elude such distinctions. Diet studies have shown overlap in food selection across their range, making them potential competitors ( Crawshaw and Quigley 2002 ; Emmons 1987 ; Leite and Galvão 2002 ; Novack et al. 2005 ; Núñez et al. 2000 ; Scognamillo et al. 2003 ; Taber et al. 1997 ). Despite the dietary overlap, no evidence new balance shoes men has been found of differentiated patterns of habitat use or activity ( Scognamillo et al. 2003 ). Camera-trap studies have compared jaguar and puma densities between multiple sites in Bolivia and Belize, showing that both cats thrive in similar habitat types across their range ( Noss et al. 2006 ).
These are excellent model species for exploring mechanisms of coexistence between larger sympatric carnivores, given their similar sizes and comparable ability to take most of the available prey in the Neotropics (up to the 40-kg white-lipped peccary [ Tayassu pecari ]).Here we analyze interactions within and between populations of jaguars and pumas in the broadleaf forest of the Cockscomb Basin in Belize. To date, only Scognamillo et al.(2003) have reported jaguar puma interactions, from telemetry data on new balance sale 4 jaguars and 5 pumas in the Venezuelan Llanos area.
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 [img]http://www.simplypotterheads.com/images/lose/new balance sale-267aje.jpg[/img] recognition from camera-trap photographs ( Silver et al. 2004 ). |
