Experimental evidence for a role of dopamine in avian personality traits
There is increasing interest on the genetic and physiological bases of behavioural differences among individuals, namely animal persona...
Proactive common waxbills make fewer mistakes in a cognitive assay, the detour-reaching task
Reactive individuals explore and make decisions more slowly than proactive individuals, paying more attention to external cues. Reactiv...
Habitat suitability analysis reveals high ecological flexibility in a “strict” forest primate
Research of many mammal species tends to focus on single habitats, reducing knowledge of ecological flexibility. The Javan lutung (Trac...
Vocal expression of emotional valence in pigs across multiple call types and contexts
Emotions, unlike mood, are short-lived reactions associated with specific events. They can be characterized by two main dimensions, the...
Goats distinguish between positive and negative emotion-linked vocalisations
Background: Evidence from humans suggests that the expression of emotions can regulate social interactions and promote coordination wit...
Elevated sensitivity to tactile stimuli in stereotypic horses
Although stereotypic behaviors are a common problem in captive animals, why certain individuals are more prone to develop them remains ...
Expression of emotional valence in pig closed-mouth grunts: involvement of both source- and filter-related parameters
Emotion expression plays a crucial role for regulating social interactions. One efficient channel for emotion communication is the voca...
Stereotypic horses (Equus caballus) are not cognitively impaired
Stereotypies in animals are thought to arise from an interaction between genetic predisposition and sub-optimal housing conditions. In ...
Perceptual lateralisation of vocal stimuli in goats
Functional asymmetries, e.g. the preferential involvement of one brain hemisphere to process stimuli, may increase brain efficiency and...
Double quantile regression accurately assesses distance to boundary trade‐offs
1‐ Boundary trade‐offs are common among ecological, life‐history, behavioural and other traits. Depending on the traits studied, distan...
