Aggressive Ural owl mothers recruit more offspring

Spatio-temporal patterns of owl territories in fragmented forests are affected by a top predator (Ural owl)

Competitive intraguild interactions can modify the spatial and temporal territory use of predators, e.g., this phenomenon was reported among species of owls (Strigidae). This study made use of owl guild present in fragmented forests in southern Poland to investigate how the occurrence of the dominant Ural owl affects the territory distribution of subordinate (in descending order): tawny owl, bo...

Offspring of Chronic Alcoholic Mothers

same observers (K. J. and D. W. S.). Four of these children were recognised as having a similar pattern of altered growth and morphogenesis. Thereafter, two other children were ascertained by the abnormal features identified in the first four patients, while the remaining two affected children were ascertained because their mothers were chronically alcoholic. The mothers of the affected patient...

Size does matter: crocodile mothers react more to the voice of smaller offspring

Parental care is widespread in Archosaurs (birds, crocodilians, dinosaurs and pterosaurs), and this group provides a useful model for the evolution of parent-offspring interactions. While offspring signalling has been well-studied in birds, the modulation of parental care in crocodilians remains an open question. Here we show that acoustic communication has a key role in the dynamics of crocodi...

Motherless quail mothers display impaired maternal behavior and produce more fearful and less socially motivated offspring.

Early maternal deprivation impairs the behavioral development of young individuals. Recently, strong differences between mothered and maternally deprived chicks have been reported concerning their emotionality, sociality, and spatial skills. Here we investigated long-term and cross-generational impacts of maternal deprivation by comparing the characteristics of the non-reproductive and the mate...
