Origin and composition of organic N forms and related stabilization mechanisms in a soil chronosequence (Project)

This project aims at the mechanisms of organic nitrogen (N) stabilization in native rainforest soils with special emphasis on the mineralogical control. It bases on the `long substrate aging gradient¿ chronosequence at Hawaiian Islands (USA) that covers substrate ages from 300 to 4.1 × 106 years at otherwise fairly constant environmental variables. This allows to track changes in organic N...

Need for sharp phenotypes in QTL detection for calving traits in German dairy cattle (Project)

The aim of the study was to investigate whether parity-specific phenotypes provide a clearer picture of QTL affecting calving traits in German Holsteins than breeding values estimated across parities. In experiment I, approximate daughter yield deviations were calculated by applying a univariate sire model assuming unrelated sires used as phenotypes in a QTL mapping study. These results were...
