Determinació per factors ambientals de la proporció de sexes a les poblacions: Mecanismes, contribució de l'epigenètica i aspectes adpatatius en un context de canvi global

Abstract

La proporció de sexes és un paràmetre fonamental en la demografia de les poblacions. Es presenta el coneixement que actualment es té sobre els mecanismes moleculars que la determinen i com en molts casos hi ha una participació combinada d’elements genètics i factors ambientals. La epigenètica integra la informació genòmica amb la ambiental i és la base de la plasticitat fenotípica Es repassen breument els principals mecanismes epigenètics i diferents mètodes per a avaluar canvis en la metilació del DNA.Seguidament, es presenten exemples de com la epigenètica pot contribuir en la recerca en ecologia i, de passada, en la producció animal. Per acabar, mostrarem alguns exemples de recerca en epigenòmica en poblacions naturals de les Illes Medes, de com petites variacions en les condicions ambientals al principi de la vida tenen conseqüències a llarg termini, i discutirem breument aspectes adaptatius en un context de canvi global
