Contingency and determinism in the evolution of bird song sound frequency
Sexual signals are archetypes of contingent evolution: hyper-diverse across species, often evolving fast and in unpredictable direction...
An exploratory investigation of glucocorticoids, personality and survival rates in wild and rehabilitated hedgehogs (Erinaceus europaeus) in Denmark
The European population of hedgehogs ( Erinaceus europaeus ) is declining. It is therefore essential to optimise conservation initiativ...
Contrasting use of space by two migratory Afro-Palearctic warblers on their African non-breeding grounds
In migratory birds, constraints due to breeding are relaxed during the non-breeding season and thus, social behaviours and spatial asso...

Conservation of Long-tailed macaques: implications of the updated IUCN status and the COVID-19 pandemic
The often synanthropic long-tailed macaque (Macaca fascicularis) is listed in Appendix II of CITES and was recently updated to Vulnerab...
The allometry of sound frequency bandwidth in songbirds
Theory predicts that allometric constraints on sound production should be stronger for the lower frequencies of vocalizations than for ...
Stereotypic behaviour in horses lowers stress but not spatial learning performance
Stereotypies are common in captive animals, but it remains unclear if they are pathological by-products of captive conditions or if the...
Comparative home range size and habitat selection in provisioned and non-provisioned long-tailed macaques (Macaca fascicularis) in Baluran National Park, East Java, Indonesia
The effect of food provisioning on ranging patterns of long-tailed macaques (Macaca fascicularis) in non- anthropogenic areas is largel...
Estimating densities and spatial distribution of a commensal primate species, the long‐tailed macaque (Macaca fascicularis)
Knowledge about distribution of primate species and their densities is crucial for conservation and management. However, such informati...
