C. Both, Auteur ; R. G. Bijlsma, Auteur ; M. E. Visser, AuteurClimate change has advanced the breeding dates of many bird species, but for few species we know whether this advancement is sufficient to track the advancement of the underlying levels of the food chain. For the long-distance migratory pied fly[...]![]()

C. Both, AuteurThe presence of density dependence of clutch size is tested in 57 long-term population studies of 10 passerine bird species. In about half of the studies of tit species Parus spp. density dependence of clutch size was found, while none was found[...]![]()
Article
C. Both, AuteurTerritory defence has been suggested to serve as a means of preventing extrapair copulations. This hypothesis predicts that territory size is largest during the fertile period, and hence at this time few new territory settlements are expected. I[...]![]()
