Molecular determination of sex and paternity of nestlings in populations of the meadow pipit (Anthus pratensis).

Original language description

The aims of our study were to determine nestlings sex ratio and frequency of extra-pair paternity (EPP) in several populations of meadow pipit (Anthus pratensis) breeding in Tydal province in the Central Norway (1998, 2000), and in the Jeseníky Mountains(1999, 2001) and the Krkonoše Mountains (2001, 2002) in the Czech Republic. The meadow pipit is a small passerines building the nests on the ground in open habitats of the West Palearctic. Pipit nestlings do not show any feature of external sexual dimorphism. Their sex was determined by using DNA sexing technique. This method is based on finding of the first W-linked avian gene CHD1 (Griffiths and Tiwari 1995). This gene has become a universal marker for DNA sexing in birds. It exists in very similar copies (CHD-Z, CHD-W) differing in the length of introns and therefore the results show two DNA fragments in females (ZW), but only single one in males (ZZ). The frequency of EPP was detected by analysing the microsatellite DNA. Microsatel

Czech description

Cílem studie byla determinace hnízdního poměru pohlaví a frekvence mimopárového rodičovství (EPP) u několika populací Anthus pratensis hnízdící in Tydal provincii ve Středním Norsku (1998, 2000), a pohořích Jeseníky (1999, 2001) a Krkonoše (2001, 2002) vČeské republice. Výsledky indikují, že během studovaného období (1998-2002) průměrné poměry pohlaví ve sledovaných populacích byly 0.7M:1.0F v Jeseníkách; 1.5M:1.0F v Krkonoších; a 0.9M:1.0F v Norsku. Naše výsledky také ukazují, že béhem této periody byly průměrné frekvence EPP v těchto populacích 43,9% v Jeseníkách; 40,9% v Krkonoších; a 18,3% v Norsku.
