| Abstract | Land management causes changes in forest structure and thus influences the composition and abundance of communities of forest-inhabiting bird species. However, it is unclear how these changes translate into local habitat suitability for certain bird species given that detailed knowledge on habitat use by forest bird species is still scarce. We have analyzed the habitat preferences of 37 breeding bird species in 19 lowland beech forests, each with an average size of 40 ha. We used Jacobs habitat selection index to quantify preference or avoidance of certain forest developmental phases (fdp). Fdp divide the forest life cycle into different periods, each characterized by a certain combination of habitat parameters (canopy cover, tree dimension, deadwood amount, regeneration cover), thereby integrating several age-specific structural properties. We found that fdp representing the last third of the forest life cycle were significantly preferred by most of the bird species. Of the 37 bird species analyzed, 19 showed the highest preference for the terminal phase or the disintegration phase; this was especially true for hole breeders, semi-hole breeders, ground breeders and beech forest indicator species. Moreover, each bird species showed a characteristic profile of preferred and avoided fdp. Some bird species, such as several free breeders, also preferred younger fdp, such as gaps or regeneration phases. Further, mean fdp patch size turned out to be a strong predictor of bird community composition. Our study confirms that most bird species show a strong preference for later fdp, such as the terminal phase and disintegration phase. However, the simultaneous availability of a mixture of different fdp on local scales meets the habitat preferences of most species and promotes biodiversity of breeding bird communities in lowland beech forests. Waldentwicklungsphasen als ein integrierendes Werkzeug zur Beschreibung von Habitatpräferenzen von Brutvögeln innerhalb von Tieflandbuchenwäldern Die Bewirtschaftung von Wäldern bewirkt verschiedenste Veränderungen in deren Struktur und beeinflusst dadurch die Zusammensetzung und Abundanz der dort vorkommenden Arten. Dabei ist jedoch der Einfluss dieser Veränderungen auf die lokale Habitatstruktur noch unklar und es mangelt an Kenntnissen zu detaillierter Habitatnutzung durch verschiedene Brutvogelarten. Wir haben Habitatpräferenzen von 37 Brutvogelarten in 19 jeweils ca. 40 Hektar großen Buchenwaldgebieten untersucht. Mit Hilfe des Jacobs Index wurde das artspezifische Präferenz- und Meidungsverhalten für bestimmte Waldentwicklungsphasen (WEP) bestimmt. WEP unterteilen den Lebenszyklus des Waldes in verschiedene Abschnitte, die jeweils durch eine bestimmte Kombination von Habitatparametern wie Kronenschlussgrad, Baumdimension, Totholzanteil und Deckungsgrad der Verjüngung charakterisiert sind, wobei alterstypische, strukturelle Eigenschaften integriert werden. Unsere Ergebnisse zeigen, dass die WEP im letzten Drittels des Lebenszyklus eines Waldes von den meisten Vogelarten bevorzugt werden. 19 von 37 Arten präferieren die Terminal- oder Zerfallsphase am stärksten, insbesondere Höhlenbrüter, Halbhöhlenbrüter, Bodenbrüter sowie die Buchenwald-Leitarten. Darüber hinaus zeigt jede Vogelart ein spezifisches Profil, das sich aus präferierten und gemiedenen WEP zusammensetzt und sich zwischen den Arten deutlich unterscheidet. Einige Arten, z.B. Freibrüter, bevorzugen auch jüngere WEP wie beispielsweise Lücken oder Verjüngungsphasen. Desweiteren erwies sich die mittlere WEP-Patchgröße als bedeutender Faktor für die Artenzusammensetzung der Brutvogelgemeinschaft eines Waldbestandes. Unsere Untersuchung unterstreicht, dass die meisten Brutvögel spätere WEP bevorzugen. Dennoch deckt sich das gleichzeitige Vorkommen aller WEP in einer kleinteiligen mosaikähnlichen Struktur mit den Habitatpräferenzen der Vögel und begünstigt die Biodiversität von Brutvogelgemeinschaften in Tiefland-Buchenwäldern. |

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.
