| Abstract | In this study we tested the hypothesis that the European hareLepus europeaeus avoids areas around nests of the ravenCorvus corax built on electricity pylons in an intensively used farmland. Hare counts were conducted in spring 1999 and 2000 in areas of 1000 m length and 200 m width along 47 transect lines starting from pylons with raven nests. Likewise, 47 control areas along transect lines, which started from pylons without any nests were studied. The two types of transects did not differ with respect to the number of recorded hares. The main factor influencing hare occurrence in farmland was found to be habitat diversity.Geprüft wurde, ob Feldhasen in intensiv landwirtschaftlich genutzten Gebieten die Umgebung von Kolkrabennestern meiden. Dazu wurden im Frühjahr 1999 und 2000, ausgehend von Strommasten mit Rabennestern, auf 47, jeweils 1000 Meter langen und 200 Meter breiten Transektflächen Hasenzählungen durchgeführt. Die ermittelten Werte wurden mit denen von 47 gleich gearteten Kontrolltransekten verglichen, die von Masten ohne Rabennest ausgingen. Die Anzahl der entdeckten Hasen unterschied sich nicht signifikant zwischen den beiden Transekttypen. Entscheidend für die Verteilung der Hasen in der Agrarlandschaft war die Habitatdiversität.Dans cette étude a été testée l'hypothèse suivant laquelle, dans une exploitation agricole intensive, le Lièvre d'Europe évite le voisinage de nids de Grand Corbeau construits sur des pylones électriques. Des comptages ont été effectués au printemps 1999 et 2000 sur des sites de 1000m de longueur et de 200m de large le long de 47 transects au départ de pylones où se trouvaient des nids de Grand Corbeau. De façon analogue, 47 sites de contrôle ont été étudiés le long de transects au départ de pylones dépourvus de nids. Les deux types de transects ne différaient pas quant au nombre de lièvres recensés. Le facteur principal influençant l'occurrence de lièvres dans l'espace agricole s'est avéré être la diversité de l'habitat. |

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.
