Diagnosis and treatment of occipital brain lesions in children

open access: yesDevelopmental Medicine &Child Neurology, EarlyView.
Occipital brain lesions in children represent a diagnostic challenge due to the large spectrum of etiologies and overlapping clinical features. This review analyses common and less common causes of occipital brain lesions in children, including malformative, vascular, genetic/metabolic, infectious, inflammatory, and neoplastic conditions.

Function of Duet Coordination in a Territorial Socially Monogamous Bird

open access: yesEthology, EarlyView.
Responses to playback of coordinated and uncoordinated duets in the Chirruping wedgebill, an antiphonal duetter, measured as response intensity (PCA including distance to speaker, latency to vocalise, vocalisation rate and vocalisation duration) and note‐by‐note coordination of the response. ABSTRACT Duetting, a cooperative vocal behaviour performed by

Experimental evidence of slight alteration of male Collared Flycatcher songs based on the female audience

open access: yesIbis, EarlyView.
Bird song is an important and variable sexual signal in many passerine species. One function of this variability may be that males show mate choice and can alter their song according to the quality of the female to which they are singing. If attractive songs are costly, we can hypothesize that males sing more attractively or invest more in singing when

Individuality obscures geographical song variation in two passerine sister species with contrasting distributions and movement ecology

open access: yesIbis, EarlyView.
Songbirds are a well‐established model group for the study of cultural evolution as their songs are learned (i.e. culturally transmitted), which may lead to divergence in song characteristics between populations. Song variation across populations may be affected by geographical isolation, timing and duration of the learning period, and life strategies ...
