| Abstract | Mittels Population Viability Analysis wurden Veränderungen in der Wachstumsrate von Rotfuchspopulationen infolge der Tollwutimmunisierung untersucht. Dazu wurden Reproduktionsdaten und Altersverteilungen aus veröffentlichten Studien mit Jagdstrecken und Fallwilduntersuchungen zur Berechnung von Populationsmodellen verwendet. Diese zeigten eine vorübergehend erhöhte Wachstumsrate in den ersten Jahren nach der Immunisierung. Bereits nach weniger als zehn Jahren ging diese zurück. Ein dauerhaftes Anwachsen der Fuchspopulationen war nicht nachzuweisen. Wahrscheinlich stabilisierten sich die Bestände inzwischen auf höherem Niveau. Diese Annahme wird auch durch regionale Jagdstrecken und Baukartierungen gestützt. Für ostdeutsche Marderhunde ergab dieser Ansatz ähnliche Wachstumsraten wie für eine Fuchspopulation unmittelbar nach der Immunisierung. Die Aussagekraft der Modellrechnungen wird diskutiert.Red FoxVulpes vulpes population growth before and after rabies vaccination was investigated using population viability analysis. I constructed life tables to assess mortality rates using age distribution and reproductive parameters from published studies mainly based on hunting bags and road kills. Models based on these mortality estimates together with estimates of reproduction revealed temporarily increasing growth rates in fox populations immediately after rabies vaccination. Less than ten years after rabies eradication growth rates had decreased again. Like these models bag statistics and mapping of breeding dens also confirm that populations probably stabilized at a higher level in the end of the 1990s. For the eastern German Raccoon dogNyctereutes procyonoides populations the model shows high growth rates like in a fox population shortly after rabies vaccination. The validity of model estimates depending on the certainty of parameters is discussed.Au moyen d'une analyse de viabilité de population, les modifications du taux d'accroissement de populations du Renard résultant de la vaccination anti-rabique ont été étudiées. A cet effet, des données publiées sur la reproduction et sur les répartitions de classes d'âge ont conjointement été utilisées avec des tableaux de tir et de mortalités pour établir des modèles de population. Ceux-ci montrèrent un taux d'accroissement en augmentation passagère au cours des premières années suivant la vaccination. Après moins de dix ans, ce taux allait diminuant de telle sorte qu'une augmentation durable des populations de renards ne se remarquait plus. Sans doute les effectifs s'étaient-ils entretemps stabilisés à un niveau plus élevé. Cette supposition est également corroborée par des tableaux de tir régionaux et par la cartographie des terriers. Pour le Chien viverrin d'Allemagne de l'Est, cette modélisation donna lieu à des taux d'accroissement analogues à ceux observés pour une population de renards aussitÔt après l'opération d'immunisation. La pertinence du modèle avancé fait l'objet d'une discussion. |

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.
