Influence of fine-scale habitat structure on nest-site occupancy, laying date and clutch size in Blue Tits Cyanistes caeruleus

Autor: Oscar Vedder, Elske Schut, Jan Komdeur, Peter Korsten, Seyed Mehdi Amininasab, Michael J. L. Magrath, Berber de Jong

Publikováno v: Acta oecologica-International journal of ecology, 70, 37-44. ELSEVIER SCIENCE BV

Most birds have specific habitat requirements for breeding. The vegetation structure surrounding nest sites is an important component of habitat quality, and can have large effects on avian breeding performance. We studied 13 years of Blue Tit Cyanis

Sperm depletion does not account for undeveloped eggs in blue tits Cyanistes caeruleus

Autor: Michael J. L. Magrath, Jan Komdeur, Elske Schut, Oscar Vedder

Hatching failure negatively impacts reproductive success in birds. One reason why eggs fail to hatch is that they are not fertilized, which may be because they receive insufficient sperm. In most passerines, copulation declines in frequency or ceases

Polygyny and extra-pair paternity enhance the opportunity for sexual selection in blue tits

Polygyny and extra-pair paternity are generally thought to enhance sexual selection. However, the extent to which these phenomena increase variance in male reproductive success will depend on the covariance between success at these two strategies. We

Ultraviolet crown colouration affects contest outcomes among male blue tits, but only in the absence of prior encounters

Summary 1. Static animal colour patches may function among competitors to minimize conflict escalation over resources, by serving as a signal of resource holding potential or aggressiveness. Empirical evidence for the use of colour patches in conflic

Parthenogenesis in a passerine bird, the Zebra Finch Taeniopygia guttata

Autor: Tim R. Birkhead, Elske Schut, Nicola Hemmings

Publikováno v: Ibis. 150:197-199

Parthenogenesis is defined as cell division in a female gamete without any genetic contribution from the male (Beatty 1967, Rougier & Werb 2001). When such cell division results in the development of an embryo parthenogenesis is known as ‘virgin bi

In this study, we partly characterize major histocompatibility complex (MHC) class II B in the blue tit (Cyanistes caeruleus). A total of 22 individuals from three different European locations: Spain, The Netherlands, and Sweden were screened for MHC

The major histcompatibility complex (MHC) is a vital component of the adaptive immune system in all vertebrates. This study is the first to characterize MHC class I (MHC-I) in blue tits (Cyanistes caeruleus), and we use MHC-I exon 3 sequence data fro

Reduced extrapair paternity in response to experimental stimulation of earlier incubation onset in blue tits

Publikováno v: Behavioral Ecology, 21(1), 9-15. Oxford University Press

Although the causes and consequences of extrapair paternity (EPP) have been studied extensively in birds, little is known about the regulation of extrapair copulation (EPC) behavior and how it may tie in with other aspects of avian reproduction. In b
