Acoustic Analysis Of Cattle (Bos Taurus) Mother–Offspring Contact Calls From A Source–Filter Theory Perspective, Mónica Padilla De La Torre, Elodie F. Briefer, Tom Reader, Alan G. Mcelligott Sep 2016

Acoustic Analysis Of Cattle (Bos Taurus) Mother–Offspring Contact Calls From A Source–Filter Theory Perspective, Mónica Padilla De La Torre, Elodie F. Briefer, Tom Reader, Alan G. Mcelligott

Elodie Briefer, PhD

Cattle vocalisations have been proposed as potential indicators of animal welfare. How-ever, very few studies have investigated the acoustic structure and information encoded in these vocalisations using advanced analysis techniques. Vocalisations play key roles in a wide range of communication contexts; e.g. for individual recognition and to help coordinate social behaviours. Two factors have greatly assisted our progress in developing an understanding of animal vocal communication. Firstly, more rigorous call analysis methods allow us to describe the variation in the vocal parameters in unprecedented detail. Secondly, the adoption of the “source–filter theory” of call production links the acoustic structure of …


A Survey Of The Management And Development Of Captive African Elephant (Loxodonta Africana) Calves: Birth To Three Months Of Age, Nicole L. Kowalski, Robert H.I. Dale, Christa L. H. Mazur Jun 2014

A Survey Of The Management And Development Of Captive African Elephant (Loxodonta Africana) Calves: Birth To Three Months Of Age, Nicole L. Kowalski, Robert H.I. Dale, Christa L. H. Mazur

We used four surveys to collect information about the birth, physical growth, and behavioral development of 12 African elephant calves born in captivity. The management of the birth process and neonatal care involved a variety of standard procedures. All of the calves were born at night, between 7PM and 7AM. The calves showed a systematic progression in behavioral and physical development, attaining developmental milestones at least a quickly as calves in situ. This study emphasized birth-related events, changes in the ways that calves used their trunks, first instances of behaviors, and interactions of the calves with other, usually adult, elephants. …
