Occurrences of non-linear phenomena and vocal harshness in dog whines as indicators of stress and ageing [PDF]
Scientific Reports, 2021 During social interactions, acoustic parameters of tetrapods’ vocalisations reflect the emotional state of the caller. Higher levels of spectral noise and the occurrence of irregularities (non-linear phenomena NLP) might be negative arousal indicators in

The newly described Araguaian river dolphins, Inia araguaiaensis (Cetartiodactyla, Iniidae), produce a diverse repertoire of acoustic signals [PDF]
PeerJ, 2019 The recent discovery of the Araguaian river dolphin (Inia araguaiaensis) highlights how little we know about the diversity and biology of river dolphins. In this study, we described the acoustic repertoire of this newly discovered species in concert with

Tidal currents and mixing in the Lake Maracaibo estuarine system
Scientia Marina, 2001 The Lake Maracaibo estuarine system is a cooscillating coupled ocean-lake system connected through a partially mixed estuary. In this paper we examine the low frequency movements (w < 0.1 cycles/day) in the different water bodies within this system.
