Aggressive responses to broadband trills are related to subsequent pairing success in nightingales [PDF]

, 2017
In sexually selected signals, distinct components often have specific signal value in mate choice or male-male competition. In songbirds, structural song traits such as trills, that is, a series of repetitive notes, can be important in female choice ...

Wild Animal Suffering Is Not Intractable: A Precautionary Approach to Compassionate Intervention

Journal of Applied Philosophy, EarlyView.
ABSTRACT Wild animals suffer due to human activity, yet natural factors contribute far more significantly to their suffering. In light of this, some propose that we have a pro tanto obligation to intervene in ecosystems to improve wild animal welfare.

Communication across territory boundaries: distance-dependent responses in nightingales [PDF]

, 2017
In communication, vocal signals are often used for long-range signaling. Yet, little experimental evidence is available on the role of territorial signals across territory boundaries and their effectiveness at different propagation distances.

Fruit use and fruit processing by euphonias, specialized avian frugivores

Oikos, EarlyView.
Euphonias (Neotropical passerines in the genera Euphonia and Chlorophonia) form the quintessential example of a specialized avian frugivore, combining a high reliance on fruit as food and the restriction of fruit taxa exploited. To understand their specialization, we explored the integration of fruit morphological and nutritional traits with their ...

"Catechima laburra", zubereraren ezaugarri fonologikoen lekukoa

Anuario del Seminario de Filología Vasca "Julio de Urquijo", 2013
In this paper we propose a phonological analysis of the souletin writer Belapeire's Catechima laburra ("Short Catechism") (1696), which seems reliably to reflect many phonetic traits of his dialect, as shown by the comparison with other texts, mainly ...

The violability of backness in retroflex consonants [PDF]

, 2005
This paper addresses remarks made by Flemming (2003) to the effect that his analysis of the interaction between retroflexion and vowel backness is superior to that of Hamann (2003b).

Cooperative human signals to honeyguides form local dialects

People and Nature, EarlyView.
Abstract Human language enables the exchange of complex information and precise instructions for collaborative planning and action. It rapidly evolves through social learning, generating diverse cultural communication signals used not only with other humans, but also with domesticated animals bred or trained to respond.

The weight of phonetic substance in the structure of sound inventories [PDF]

, 2013
In the research field initiated by Lindblom & Liljencrants in 1972, we illustrate the possibility of giving substance to phonology, predicting the structure of phonological systems with nonphonological principles, be they listener-oriented (perceptual ...

Using programmable infusion pump in avian species – a validation methodology in geese

Wildlife Biology, EarlyView.
Wildlife face anthropogenic and natural stressors that affect their physiology and behaviour. The activity of the hypothalamic–pituitary–adrenal axis and glucocorticoid (GC) production is intrinsically linked with energy regulation and environmental stressors.
