[EN] The main objectives of the project were 1) to determine whether supplementary feeding had a positive effect on reproduction of the Iberian lynx, 2) the development of non-invasive techniques for the mon- itoring of lynx populations, 3) the study of distribution and abundance of domestic and generalist carnivores of the Doñana National Park (PND) using primarily census tracksurveys, and 4) to evaluate the effectiveness of campaigns to control the red fox population as usually performed within PND, also using tracksurveys. Litter size in the Doñana lynx population during the study period was lower than that observed years ago despite the supplementary feeding program. The simultaneous use of came- ras and genetic analysis of faecal DNA was useful to track the population of resident lynx. The red fox was the most widely distributed species, followed closely by Egyptian mongooses and European bad- gers. The other species of carnivores were always detected in less than 50% of the sampled shrubland area. Most cats detected in the PND were wild cats, and a lower domestic. Finally, the populations of foxes did not appear to respond to the control campaigns of the PND. In addition, detailed monitoring of 2 foxes tracked with GPS collars showed that a single individual can cross on average 10 times 1 km of road inside the PND.

El tamaño de ca- mada en la población de linces de Doñana durante el periodo de estudio fue menor de lo ...
