Avian hissing sounds: occurrence, mechanism, ontogeny, function and phylogeny Open
Sound production is widespread across the animal kingdom and can take many forms and serve various functions. A hissing sound is a non-vocal acoustic signal produced by forced air ventilation and is hypothesized to be a behavioural symples…
No relationship between chronotype and timing of breeding when variation in daily activity patterns across the breeding season is taken into account Open
There is increasing evidence that individuals are consistent in the timing of their daily activities, and that individual variation in temporal behavior is related to the timing of reproduction. However, it remains unclear whether observed…
Serotonin transporter (SERT) polymorphisms, personality and problem-solving in urban great tits Open
Understanding underlying genetic variation can elucidate how diversity in behavioral phenotypes evolves and is maintained. Genes in the serotonergic signaling pathway, including the serotonin transporter gene ( SERT ), are candidates for a…
Nest defence behavioural reaction norms: testing life-history and parental investment theory predictions Open
Predation is the primary source of reproductive failure in many avian taxa and nest defence behaviour against predators is hence an important aspect of parental investment. Nest defence is a complex trait that might consistently differ amo…
The Female Perspective of Personality in a Wild Songbird: Repeatable Aggressiveness Relates to Exploration Behaviour Open
Males often express traits that improve competitive ability, such as aggressiveness. Females also express such traits but our understanding about why is limited. Intraspecific aggression between females might be used to gain access to repr…
Five of Five VHHs Neutralizing Poliovirus Bind the Receptor-Binding Site Open
Nanobodies, or VHHs, that recognize poliovirus type 1 have previously been selected and characterized as candidates for antiviral agents or reagents for standardization of vaccine quality control. In this study, we present high-resolution …
