  • New concepts and methods for phylogenetic taxonomy and nomenclature in zoology

    Although currently most taxonomists claim to adhere to the concept of ‘phylogenetic taxonomy’, in fact most of the zoological classifications currently published are only in part ‘phylogenetic’ but include also phenetic or gradist approaches

  • Alloparental care in glassfrogs: males care for unrelated clutches only when associated with their own

    Parental care is costly, thus theory predicts that parents should avoid caring for unrelated offspring. However, alloparenting has been reported in many taxa because it may increase the caregiver mating success or offspring survival. We ...
