Abstract
Programma Vigoni Collaborazione Italia-Germania 2011-2012 Nocturnally migratory birds interrupt migration temporarily if they have depleted energy reserves and find suitable ‘refuelling’ sites. Besides weather conditions, a major determinant of whether a bird rests or continues migration is body fat. We are interested in understanding which physiological mechanisms switch on and off nocturnal migration during and after refuelling at a stop-over site. We have identified a candidate hormone, ghrelin, that may be a major player in influencing decisions to migrate or not. The aim of this project is to substantiate (or disprove) the evidence for the role of ghrelin in the regulation of migratory behavior.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
