Synergy Between Behavioural Research On Beluga Whales (Delphinapterus Leucas) Conducted In Zoological And Wild Settings, Heather Manitzas Hill, Deirdre Yeater, Michael Noonan

Behavioural observations of captive beluga whales have complemented and extended much of what has been learnt about this species in the wild. Aquarium-based research has provided finer-scale specificity for many topics, including the seasonal breeding pattern that is characteristic of this species, as well as socio-sexual behaviour that appears to be an important part of the behavioural repertoire of this species. One example is a strong propensity for male–male social interactions that begin to develop at an early age. In addition, detailed behavioural milestones in calves have been documented in ways that extend that which have been collected from wild …


Effects Of Amphetamine On Striatal Dopamine Release, Open-Field Activity, And Play In Fischer 344 And Sprague–Dawley Rats, Stephen M. Siviy, Lana S. Mcdowell, Samantha R. Eck, Alexandra Turano, Garnik Akopian, John P. Walsh Dec 2015

Effects Of Amphetamine On Striatal Dopamine Release, Open-Field Activity, And Play In Fischer 344 And Sprague–Dawley Rats, Stephen M. Siviy, Lana S. Mcdowell, Samantha R. Eck, Alexandra Turano, Garnik Akopian, John P. Walsh

Previous work from our laboratories has shown that juvenile Fischer 344 (F344) rats are less playful than other strains and also appear to be compromised in dopamine (DA) functioning. To determine whether the dysfunctional play in this strain is associated with deficits in the handling and delivery of vesicular DA, the following experiments assessed the extent to which F344 rats are differentially sensitive to the effects of amphetamine. When exposed to amphetamine, striatal slices obtained from F344 rats showed a small increase in unstimulated DA release when compared with slices from Sprague–Dawley rats; they also showed a more rapid high …


A Schematic For Focusing On Youth In Investigations Of Community Design And Physical Activity, Kevin J. Krizek, Amanda Birnbaum, David M. Levinson Sep 2004

A Schematic For Focusing On Youth In Investigations Of Community Design And Physical Activity, Kevin J. Krizek, Amanda Birnbaum, David M. Levinson

Department of Public Health Scholarship and Creative Works

This paper provides a first step in addressing special considerations for youth in a relatively new area of physical activity research. After reviewing the urgent need for novel approaches to increasing physical activity, the growing interest in the effects of community design are discussed. Although most discussion on this topic has focused on adults, there are important differences between youth and adults that warrant a special focus on youth and need to be accounted for. This article presents a schematic that accounts for how and where youth spend their time, decomposing the day into time spent in travel and time …
