A Study On The Relationgship Of Six Species Of Alandidae In Inner Mongolia

The relationship of six species from Alaudidae (Alauda arvensis Melanocorypha mongolica Calandrella cinerea Calandrella cheleensis Eremophila alpestris Galerida cristata) distributed in Inner Mongolia were studied from three aspects: Mostly in feather keratins, chromosomal karyotype and morphology adding.The contour feather vance, down feather and shaft of six Larks were studied by means of SDS-PAGE of feather keratins. The result of clustering analysis showed that the relationship between Alauda arvensis and Melanocorypha mongolica was closer than others; the relationship between Eremophila alpestris and Calandrella cinere was closer than that between Eremophila alpestris and Calandrella cheleensis. But the relationships between the five birds and Galerida cristata were all far. The karyotype analysis was made use of to verify the veracity of the results of feather keratins on celluler levels (The report about karyotypes of Eremophila alpestris and Calandrella cinere had not been published) . Finally, the analysis of morphology that select nineteen morphological characters of six species of Alaudidae based on the Operational Taxonomic Units (OTU) was made use of to verify the results of feather keratins. It is still needs more study that whether Eremophila alpestris and Calandrella cinere that have the closest relationship were merged into one genus.
