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. …

Selective Breeding For 50 Khz Ultrasonic Vocalization Emission Produces, Howard Cromwell
Howard Casey Cromwell
Ultrasonic vocalizations (USVs) are emitted by rodents and can signal either negative or positive affective states in social and nonsocial contexts. Our recent work has utilized selective breeding based upon the emission of 50 kHz USVs in response to standard cross species hand play—namely experimenters ‘tickling’ rats. Previous work has shown that high-tickle responsive animals (i.e., rats emitting abundant 50 kHz USVs) are gregarious and express enhanced positive emotional behaviors relative to animals exhibiting low 50 kHz USVs. The present study extends this work by examining the developmental profile of play behavior and the suppression of play behavior by predator …
