Article
German O. Garcia, Auteur ; Peter H. Becker, Auteur ; Marco Favero, AuteurKleptoparasitism is a well-known foraging tactic used opportunistically by many seabird species. However, little is known about this behaviour during the early stages of the breeding cycle and its effects on breeding performance. Here, we invest[...]

K. Lesley Szostek, Auteur ; Peter H. Becker, Auteur ; Barbara C. Meyer, Auteur ; Stefan R. Sudmann, Auteur ; Heribert Zintl, AuteurDensity is known to be an important factor in population size regulation. Several mechanisms of density limitation have been identified in colonial birds. We studied competition in Common Terns Sterna hirundo to assess whether the factor limitin[...]

Article
Peter H. Becker, Auteur ; Ute Sommer, AuteurWe studied concentrations of environmental chemicals in Common Tern eggs collected in 1995 at 11 marine and freshwater sites in Central Europe (Warta, Poland: 1990). For all substances studied significant between-site differences were found: hig[...]
Article
Stefan Thyen, Auteur ; Peter H. Becker, AuteurData collected in the framework of the project "Monitoring Pollutants in Coastal Bird Eggs" along the German North Sea coast in 1998 are presented and compared with several contamination studies conducted at Central European breeding sites durin[...]
Article
Andreas Daenhardt, Auteur ; Tido Fresemann, Auteur ; Peter H. Becker, AuteurPrey availability to seabirds has a profound influence on individual decisions about allocating somatic and reproductive investment. These decisions can be expressed in foraging behavior and prey utilization and have consequences for establishin[...]

Article
Sonja C. Ludwig, Auteur ; Peter H. Becker, AuteurMating between close relatives can have deleterious effects on reproductive success or offspring fitness, which should favour the evolution of active or passive inbreeding avoidance mechanisms. In birds, evidence for active inbreeding avoidance [...]
Article
German O. Garcia, Auteur ; Peter H. Becker, Auteur ; Marco Favero, AuteurKleptoparasitism is a well-known foraging strategy used opportunistically by many seabirds. Here, we investigated the effect of intraspecific kleptoparasitism on chick growth and reproductive output in Common Terns Sterna hirundo. Effects were c[...]
Article
Peter H. Becker, AuteurFrom 1981 to 1996 the reproductive success of Common Terns was studied at 3-5 colony sites at the Jade in the German Wadden Sea (Lower Saxony). The total population as well as the biggest colony on the island Minsener Oldeoog (MO) showed no tren[...]

Stefan Thyen, Auteur ; Peter H. Becker, Auteur ; Klaus-Michael Exo, Auteur ; Bernd Haelterlein, Auteur ; Hermann Hoetker, Auteur ; Peter Suedbeck, AuteurIn the framework of the "Trilateral Monitoring and Assessment Program" (TMAP), a pilot study on monitoring breeding success of coastal birds was carried out in 1996 and 1997. The objective of this study was to test the applicability of the metho[...]

Article
Helmut Wendeln, Auteur ; Peter H. Becker, AuteurSince 1992 we perform a long-term population study of Common Terns breeding in the harbor area of Wilhelmshaven, German Wadden Sea coast. We use subcutaneously injected passive transponders for life-long individual identification. All fledged ch[...]
Article
Alexander Braasch, Auteur ; Carmen Schauroth, Auteur ; Peter H. Becker, AuteurOnce a bird has fledged it becomes hardly accessible for researchers and consequently knowledge about post-fledging ontogeny is scarce. In this study on juvenile Common Terns (Sterna hirundo) we used an automated transponder-based detection and [...]
Article
Carmen Schauroth, Auteur ; Peter H. Becker, AuteurWe studied the inter-year and inter-sex variation of the post-fledging body mass development of Common Terns Sterna hirundo in 2000 and 2001 at the Banter See colony, northern Germany. Here, post-fledglings can be identified and weighed remotely[...]
Article
Peter H. Becker, Auteur ; Stefan R. Sudmann, AuteurThe results of a symposium on Common Term conservation held in Wilhelmshaven, Germany, in October 1997 are summarized. In 1996 about 8,500 pairs of Common Tern bred in Germany. The inland population has more than doubled since 1980. However, pop[...]

Mara M. Benito, Auteur ; Holger Schielzeth, Auteur ; Jacob González-Solís, Auteur ; Peter H. Becker, AuteurAdaptive sex allocation has frequently been studied in sexually size dimorphic species, but far less is known about patterns of sex allocation in species without pronounced sexual size dimorphism. Parental optimal investment can be predicted und[...]
Article
Maria M. Benito, Auteur ; Jacob González-Solís, Auteur ; Peter H. Becker, AuteurOffspring phenotypic variation has important consequences for the future survival, reproductive success and individual fitness of nestlings, but the sex-specific reproductive value and fitness returns for parents of this variation have only rare[...]

German O. Garcia, Auteur ; Juliane Riechert, Auteur ; Marco Favero, Auteur ; Peter H. Becker, AuteurAmongst seabirds, kleptoparasitism is one of the most common types of exploitation in which individuals compete for food already procured by another forager.
