Article
T. Schmoll, Auteur ; V. Dietrich, Auteur ; W. Winkel, Auteur ; T. Lubjuhn, AuteurIn order to assess the potentially harmful consequences of blood sampling in nestling coal tits (Parus ater), we analysed fledging success, fledgling local recruitment and recruit natal dispersal for nestlings originating from 27 blood-sampled b[...]

V. Dietrich, Auteur ; T. Schmoll, Auteur ; W. Winkel, Auteur ; J. T. Epplen, Auteur ; T. Lubjuhn, AuteurDespite substantial research effort, the benefits of female extra-pair matings in socially monogamous bird species remain elusive. The "good genes" hypothesis assumes that females engage in extra-pair copulations with males of superior genetic q[...]

A. Roulin, Auteur ; W. Müller, Auteur ; L. Sasvari, Auteur ; C. Dijkstra, Auteur ; A. L. Ducrest, Auteur ; Christian Riols, Auteur ; M. Wink, Auteur ; T. Lubjuhn, AuteurIn many bird populations, individuals display one of several genetically inherited colour morphs. Colour polymorphism can be maintained by several mechanisms one of which being frequency-dependent selection with colour morphs signalling alternat[...]

Female extra-pair mating, fitness and genetic diversity: Expression in socially monogamous Coal Tits
T. Schmoll, Auteur ; F. Schurr, Auteur ; W. Winkel, Auteur ; T. Lubjuhn, Auteur
Article
J. F. Masello, Auteur ; A. Sramkova, Auteur ; P. Quillfeldt, Auteur ; J. T. Epplen, Auteur ; T. Lubjuhn, AuteurWe report on a first DNA fingerprinting study of paternity in a Psittaciform bird, the burrowing parrot Cyanoliseus patagonus. In two consecutive breeding seasons, a total of 49 families was sampled, of which 11 breeding pairs were investigated [...]
Article
W. Müller, Auteur ; J. T. Epplen, Auteur ; T. Lubjuhn, AuteurPrevious studies have shown that extra-pair fertilizations are much less frequent in Non-Passeriformes, especially in raptors, than in Passeriformes. Low breeding densities, high breeding synchrony and high rates of paternal effort have been dis[...]

S. C. Wiersch, Auteur ; T. Lubjuhn, Auteur ; W. A. Maier, Auteur ; H. Kampen, AuteurBlood samples from 94 coal tits (Parus ater), 56 great tits (Parus major) and 219 pied flycatchers (Ficedula hypoleuca), caught between 1993 and 2002 at two localities in Lower Saxony, Germany, were examined for haemosporidian infection by paras[...]
Article
T. Lubjuhn, Auteur ; T. Gerken, Auteur ; J. Brun, Auteur ; J. T. Epplen, AuteurThe frequency of extra-pair paternity was studied in a population of Coal Tits Parus ater using DNA fingerprinting technique. High values were obtained: 15 of the 20 broods investigated (75%) contained at least one nestling sired by an extra-pai[...]

Inconsistent pattern of extra-pair paternity in first and second broods of the Great Tit Parus major
T. Lubjuhn, Auteur ; J. Brun, Auteur ; T. Gerken, Auteur ; J. T. Epplen, AuteurDans Ardea (89(1) 2001)In this study we compare extra-pair paternity rates in first and second broods of 25 individual breeding pairs of the Great Tit Parus major. 24% of the first broods contained at least one nestling due to copulations outside the pair bond in cont[...]

Article
V. C. J. Dietrich, Auteur ; T. Schmoll, Auteur ; W. Winkel, Auteur ; T. Lubjuhn, AuteurDifferential survival of males and females affects the structure and dynamics of avian populations, but studying sex-specific survival rates is difficult. This is especially true for offspring if the period between hatching and first breeding is[...]
