A study of homing endonucleases: Molecular evolution and gene discovery

Homing endonuclease genes (HEGs) encode highly specific DNases responsable for the mobility and spread of group 1 introns. They are divided into four families (His-Cys box, LAGLIDADG, GIY-YIG and HNH) based on conserved protein motifs. LAGLIDADG HEGs are most numerous and widespread, while the Hi...

Magnetoreception and magnetic compass orientation in the long distance migration of the European eel

The European eel, Anguilla anguilla, a common part of the fish community in European coastal and inland waters, spawns in the Sargasso Sea. The larvae drift or migrate with currents to the coasts of Europe and North Africa. Once there, large numbers of yo ung eels grow up in widely different habi...

Hybridization in birds as studied by cross-fostering in the wild

Hybridization between species generally reduces fitness. However, hybridization, and subsequent back-crossing, may lead to the transfer of genes between species and represent an important factor as a source of new variability in the subsequent evolution o f the species. The importance of hybridiz...
