The mystery of anuran middle ear loss

The mystery of anuran middle ear loss has new insights! Most frogs have a tympanic membrane and middle ear column (the columella) that help them hear airborne sound. Despite being well known for their calls, many frogs and toads are...

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

Episodic correlations in behavioural lateralization differ between a poison frog and its mimic

Sensory and behavioural lateralization is thought to increase neural efficiency and facilitate coordinated behaviour across much of the animal kingdom. Complementary laterality, when tasks are lateralized to opposite...

Necrophiliac behaviour in the recently described species Scinax tsachila (Anura: Hylidae)

Necrophilia in amphibians is a poorly known behaviour despite its potential as a beneficial adaptation for improving reproductive success. Here, we describe the observation of a multiple amplexus involving necrophilia in the recently...

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 ...
