The highest known density of this species is in the southern United States, and from there their density decreases northward to southern Canada. Despite the fact that México contains about 35 % of the species range, there are no data on their abundance or density in México. The objectives of this study were to document the density of bobcats from northwestern to southern México and to understand the abundance patterns of this species. Camera traps were used in combination with capture-recapture models to estimate densities. Using the MaxEnt ecological niche model, the potential distribution of the bobcat was obtained. With an effort of 2,070 camera trap days, we obtained 41 bobcat photographs in five localities from 2005 to 2007. Our estimated bobcat densities varied from 0.05 to 0.53 bobcat/km2. Using MaxEnt, we estimated the available habitat in each site and extrapolated the density data to obtain a range of bobcat population estimates per site. The areas estimated were between 1,861 to 16,663 km2, with a population from 592 to 2,161 bobcats. Bobcat density in México is highest in the north and decreases to the south of its range. Probably the optimal habitat for this species is found in the southern United States and northern México where the highest densities of its entire distribution occur.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[Resumen: El lince (Lynx rufus) se distribuye a lo largo de América del Norte. Sin embargo, sus densidades solo han sido documentadas principalmente en los Estados Unidos. La densidad más alta conocida para esta especie se encuentra en el sur de los Estados Unidos. Desde allí su densidad disminuye hacia el norte hasta el sur de Canadá. A pesar de que en México se estima que se encuentra el 35% de su distribución no hay datos sobre su abundancia ni densidad. Los objetivos de este proyecto fueron documentar las densidades del lince desde el noroeste hasta el sur de México y comprender los patrones de abundancia de esta especie. Se utilizaron trampas cámaras en combinación de modelos de captura-recaptura para estimar las densidades. Utilizando el modelo de nicho ecológico MaxEnt, obtuvimos la distribución potencial del lince. Con un esfuerzo de 2,070 días trampa obtuvimos 41 fotografías en 5 localidades de 2005 a 2007. Nuestras densidades estimadas de lince variaron de 0.05 a 0.53 linces/km2. Mediante el uso de MaxEnt estimamos el hábitat disponible en cada sitio y extrapolamos los datos de densidad para obtener un rango sobre la estimación del tamaño de la población del lince por sitio. Las áreas estimadas variaron entre los 1,861 a 16,663 km2 con poblaciones de 592 a 2,161 linces. La densidad de linces en México es más alta en el norte y disminuye hacia el sur de su distribución. Probablemente el hábitat óptimo para esta especie se encuentra en el sur de los Estados Unidos y el norte de México, donde se encuentra las densidades más altas de toda su distribución.]]></p></abstract>
