Pair bonding is a psychological construct that we attempt to operationalize via behavioral
and physiological measurements. Yet, pair bonding has been both defined differently in …

Social and genetic mating systems play an important role in natural and sexual selection, as
well as in the dynamics of populations. In socially monogamous species different genetic …

Publisher's description: Why do males of some species live with a single mate when they are
capable of fertilizing more than one female's eggs? Why do some females pair only with one …

It is increasingly acknowledged that migratory birds, notably waterfowl, play a critical role in
the maintenance and spread of influenza A viruses. In order to elucidate the epidemiology of …

In species with long-term pair relationships, behavioural compatibility between mates could
be a significant source of selection among pairs. We explored the relation between …

In barnacle geese Branta leucopsis, pair-bond members generally remain together every
day, each year, often for life. Geese that maintain long-lasting pair bonds during their lifetime …

Several hypotheses about the adaptive value of divorce in birds predict a positive effect of
breeding success on mate retention. Although some studies have provided direct support for …

To understand interspecific patterns in the strength of sexual selection, variation in the costs
and benefits of exercising mate choice needs to be evaluated. One manifestation of sexual …

Mate retention is classically considered advantageous for reproduction in monogamous
birds: because of their low fecundity, long-lived species should show the highest year-to …

There is evidence that breeding failure is associated with divorce and dispersal in many bird
species. However, deviations from the general pattern “success‐stay/failure‐leave” seem to …
