Little is known about the factors and outcomes associated with young people's subjective relationship assessments. Understanding what young people think makes their relationships 'good' or 'bad' would give us insight into what is important to them in their relationships as well as their decision-making and behaviour within them. Self-report data ...

Brood parasites usually reduce their host's breeding success, resulting in strong selection for the evolution of host defences. Intriguingly, some host individuals/populations show no defence against parasitism, which has been explained within the frame of three different evolutionary hypotheses. One of these hypotheses posits that intermediate levels of defence at ...
