| Abstract | Im Jahre 1999 wurden in zwei Zählperioden (Ende Februar bis Mitte April; Anfang Oktober bis Mitte November vereinzelt auch bis in den Dezember) mit der Scheinwerfermethode (Pegel 1986) die Feldhasen gezählt. An der Zählung haben sich 305 Reviere aus 56 bayerischen Landkreisen beteiligt.Die aus den Zähldaten errechneten Dichten der Feldhasen bewegten sich zwischen 3 und 83 Hasen pro km2 im Frühjahr und zwischen 1,2 und 147,5 Hasen pro km2 im Herbst (Bezugsfläche = Taxationsfläche).Die höchsten Dichten wurden in den Naturräumen Maintal, Mittelfränkisches Becken, Frankenhöhe, Nördlinger Ries, Dungau und Unteres Inntal festgestellt.Die Auswertung von Daten aus einzelnen Revieren, die seit 1996 Zählungen von Feldhasen durchführen, zeigt eine stetige Zunahme der Stammbesätze im Frühjahr.Mit Hilfe einer statistischen Analyse haben sich positive Korrelationen zwischen der ermittelten Hasendichte und verschiedenen Faktorenkomplexen ergeben. Demnach steigt die Hasendichte mit der Klimagunst, dem Anteil an landwirtschaftlicher Nutzfläche bzw. Getreideanbaufläche sowie dem Strukturreichtum der landwirtschaftlichen Fläche. Weitergehende Aussagen zur Landnutzung lassen sich treffen, wenn sämtliche Daten zur Landnutzung zur Verfügung stehen.In 1999 brown hares were counted using the headlight method (Pegel 1986) during the course of two counting periods (end of February to mid April; beginning of October to mid November with occasional counts continuing into December). 305 districts from 56 Bavarian counties participated in the counts.The population densities of Brown hares determined from the counts varied between 3 and 83 hares per sq. km (of total areas counted) in the spring and between 1.2 and 147.4 hares per sq. km in the fall. The highest densities were determined for the natural areas in Maintal, Mittelfränkisches Becken, Frankenhöhe, Nördlinger Ries, Dungau, and Unteres Inntal.The evaluation of data from the individual districts that have been conducting counts of brown hares since 1996 shows a steady increase in the base population in the spring.With the aid of statistical analyses positive correlations between the density of field hares and various complexes of factors were determined. Accordingly, the density of hares increases with favourable climate, the proportion of agriculturally used areas, particularly grain fields, as well as with greater diversity and natural breaks within fields. Further conclusions pertaining to land use can be made when all data have been compiled.En 1999, le Lièvre a été recensé au phare (Pegel 1986) lors de deux périodes d'inventaire, soit de fin février à mi-avril, du début octobre à mi-novembre de même que de façon ponctuelle jusqu'en décembre. Ce sont pas moins de 305 territoires relevant de 56 districts du Land de Bavière qui se sont impliqués dans cette opération de comptage. Les densités calculées à partir des relevés oscillent entre 3 et 83 lièvres au km2 au printemps et entre 1,2 et 147,5 lièvres au km2 en automne (surface de référence = surface recensée). Les densités les plus élevées ont été constatées dans les régions naturelles de la vallée du Main, dans le Bassin de la Franconie centrale, dans la Franconie supérieure, dans le Nördlingen Ries, le Dungau et la vallée de l'Inn inférieure. L'exploitation des données de territoires isolés qui organisent des inventaires de lièvres depuis 1996 montre une augmentation constante des effectifs de référence du printemps.A l'aide d'une analyse statistique, des corrélations positives ont été observées entre la densité de lièvres constatée et différents complexes de facteurs. Ainsi la densité de lièvres augmente-t-elle avec la clémence du climat, la proportion d'exploitations agricoles ou celle des cultures de céréales de même qu'en fonction de la diversité structurelle des exploitations agricoles. D'autres affirmations en relation avec l'aménagement du territoire rural peuvent être avancées lorsque des données à propos de ce dernier sont disponibles. |

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.
