| Abstract | This paper describes the distribution and epizootiology of red fox sarcoptic mange in Spain and discusses the impact of the enzootic disease on free-living fox populations. Mange distribution and trends in red fox abundance were studied in the whole Spanish mainland through direct interviews with hunters or game-keepers. In the Ebro Valley study area, fox carcasses were collected for necropsy and field data were obtained during spotlight-censuses. Mange was detected in 70 (22.5%) out of 311 localities surveyed. The analysis of log-linear parameters showed that declining fox populations were associated with mange more often than random. Overall prevalence of foxes with mange-compatible lesions in a sample of 728 (mostly shot) fox carcasses was 3.16 ± 1.3%, the prevalence of mangy foxes varying with habitat characteristics. However, in local populations of the study area, mange showed prevalences of up to 23.1% and was apparently not compensated by other mortality factors.Diese Abhandlung beschreibt die Verbreitung und Epizootiologie der Sarcoptes-Räude des Fuchses in Spanien und kommentiert den Einfluß dieser enzootischen Parasitose auf freilebende Fuchspopulationen. Die Verbreitung der Räude, sowie die Tendenzen in der Fuchsabundanz wurden im gesamten spanischen Festland durch Interviews mit Jägern und Wildwächtern erfaßt. Im Ebrotal-Studiengebiet wurden außerdem Fuchskadaver für Nekroskopien gesammelt und Nachtzählungen durchgeführt. In 70 von 311 Interview-Stellen wurde Räude beschrieben. Eine log-linear Analyse ergab, daß sinkende Fuchsbestände mit der Präsenz von Räude in Beziehung stehen. Die Prävalenz der Füchse mit Räudeläsionen unter 728 untersuchten (meist geschossenen) Exemplaren war 3.16 ± 1.3%, wobei sich Biotop-bedingte Unterschiede herausstellten. In lokalen Fuchspopulationen des Studiengebietes ergaben sich allerdings Räudeprävalenzen bis 23.1%. Die räudebedingte Mortalität wurde offensichtlich nicht durch andere Faktoren ausgeglichen.Il est décrit ici la propagation de la gale sarcoptique enzootique du renard en Espagne et commenté l'influence de cette affection parasitaire sur la population de renards vivant en liberté. La propagation de la gale tout comme les tendances de l'abondance du renard ont été étudiées par des interviews avec des chasseurs et des gardes-chasse. Dans la valleé de l'Ebro, terrain de l'étude, des cadavres de renards ont été rassemblés à fin de nécroscopie des recensements effectués de nuit. En 70 endroits de 311 ou les interviews ont été effectués, il y avait preuve de cas de gale. Une analyse log-linear a donné que la population de renard diminuait dans les lieux ou il y a avait présence de gale. La prévalence des renards montrant des lésion dues à la gale parmi les 728 exemplaires examinés (la plupart abattus) était 3.16 ± 1.3 %. La prévalence des renards atteints de gale variait selon les caractéristiques biotopes. Toutefois dans des populations locales du lieu d'étude la prevalence de gale montait jusqu'à 23.1 %. La mortalité due à la gale n'a donc pas été compensée par d'autres facteurs. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
