Mate similarity in foraging Kerguelen shags: a combined bio-logging and stable isotope investigation
Similarity or dissimilarity between 2 individuals that have formed a pair to breed can occur in morphology, behaviour and diet. Such patterns influence partners' cooperation when rearing their offspring, consequently influencing reproductive success. They may confer different benefits, dependin...

Similarity or dissimilarity between 2 individuals that have formed a pair to breed can occur in morphology, behaviour and diet.
