| Estructura de la metapoblaci˘n de linces de Do¤ana | |
| 2003 Book Chapter | |
The structure of the Do¤ana Iberian lynx metapopulation was studied using information from resident and dispersing individual radio-tracked between 1984 and 2001. Resident lynx were in 9 different nuclei of extension ranging from 260 to more than 5900 ha. Dispersing lynx connected these nuclei. The total surface occupied by resident lynx was 18230 ha. Three nuclei were inside the Do¤ana National Park, 4 total or partially within the Do¤ana Natural Park, and 2 in non-protected areas. A total of 19 potential reproduction territories were identified, distributed between the 9 nuclei. Two nuclei included 5 territories, other 2 nucleus 2 territories and the remainders only one territory. On average, the territories were 867 ha (range=210-3168). Ten (53%) of territories were within the Do¤ana National Park, 4 (21%) within the Natural Park, 3 (16%) between the Natural Park and non-protected areas, and 2 (10%) in non-protected areas. There are not resident lynx in all the areas of optimal vegetation for the species, which might be due to rabbit scarcity and high human disturbance. Not all territories and nucleus have been always occupied by lynx, which is in accordance with metapopulation theory. A census carried out in summer-autumn 2001 showed absence of tracks in 5 territories (2 of them belonging to nucleus with only a territory). The resident lynx did not reproduce every year as evidence of reproduction was only found in six of the territories. |
