Cortisol levels in dolphin Tursiops truncatus interactive programs linked to humanNiveles de cortisol en delfines Tursiops truncatus vinculados a programas interactivos con humanos
Contributor(s):: Sanchez Okrucky, R., Morales Vela, B.
Understanding the physiological changes in animals during physical activity to improve animal welfare has become increasingly important in animal collections that remain under human care. To date, the effect of interactive programs on dolphins under human care has not been evaluated, for that...
Survival of bottlenose dolphin ( Tursiops sp.) calves at a wild dolphin provisioning program, Tangalooma, Australia
Contributor(s):: Neil, D. T., Holmes, B. J.
Mortality of calves born to provisioned mothers is identified in the literature as an issue of concern in dolphin provisioning programs. Wild dolphin provisioning at Tangalooma, Moreton Island, Australia has been occurring since 1992. Each evening, up to eight dolphins are provided with fish in a...
Behavior of a solitary sociable female bottlenose dolphin ( Tursiops truncatus ) off the coast of Kent, southeast England
Contributor(s):: Eisfeld, S. M., Simmonds, M. P., Stansfield, L. R.
This article provides a report of the behavior of a solitary sociable dolphin studied on the southeast coast of England in 2007. This is the first study of its kind in which behavior of such a nonhuman animal was systematically studied. By the time of this study, this young female was highly...
Effects of pool size on free-choice selections by Atlantic bottlenosed dolphins at one zoo facility
Contributor(s):: Shyan, M. R., Merritt, D., Kohlmeier, N. M., Barton, K., Tenge, J.
Dolphin pool design often derives from the concept that cetaceans are ocean based and ipso facto should live in open, deep, watery spaces. This emotionally appealing rationale is not data driven. Researchers report that in the wild, some populations of Atlantic bottlenosed dolphins Tursiops...

Conflict and reconciliation behavior trends of the bottlenose dolphin ( Tursiops truncatus )
Contributor(s):: Holobinko, A., Waring, G. H.
Wild bottlenose dolphin (Tursiops truncatus) populations display societal structures characterized by numerous and frequent changes in group composition, complex social relationships, and high levels of cooperation, attributes also observed in human and nonhuman primate cultures. Maintaining...
Increased number of whistles of bottlenose dolphins, Tursiops truncatus , arising from interaction with people
Contributor(s):: Akiyama, J., Ohta, M.
The acoustic mode is the most reasonable means for social animals such as dolphins to maintain contact in the underwater habitat, and has been developed since they moved to the sea. This study investigates variations in dolphin vocalizations under the following conditions in a captive...
Behavioural responses of captive common dolphins Delphinus delphis to a 'Swim-with-Dolphin' programme
Contributor(s):: Kyngdon, D. J., Minot, E. O., Stafford, K. J.
We monitored the effects of a `Swim-with-Dolphin' (SWD) programme on the behaviour of three female common dolphins. They were studied from January 1999 to July 1999 at Marineland, Napier, New Zealand. Before, during and after SWD sessions we recorded: (1) the use of a refuge area, (2) the...
Review of wallowing in pigs: description of the behaviour and its motivational basis
Contributor(s):: Bracke, M. B. M.
Wallowing, i.e. coating the body surface with mud, is a natural behaviour of pigs, commonly observed in feral pigs and wild boar, but rarely provided for in current housing systems for domestic pigs. Furthermore, in welfare science the subject has not been receiving much attention. This paper...
Medieval and early modern whaling in Portugal
Contributor(s):: Brito, C.
Mainland Portugal is not renowned for having been a whaling nation of significance. However, preliminary studies have brought to light enough historical references to suggest that whaling occurred from at least the 13th century, and the present work identifies 38 historical sources documenting...
Effects of the interaction with dolphins on physical and mental conditions of the elderly
Contributor(s):: Akiyama, J., Sugimoto, K., Ohta, M.
The effects of animal-assisted therapy (AAT) on the physical and physiological health of old people have been well known. In general, dogs, cats and small animals have been used at the AAT for seniors. In this study we tried to clarify physical and mental effects of the interactions of old people...
Does participation in Dolphin-Human Interaction Programs affect bottlenose dolphin behaviour?
Contributor(s):: Trone, M., Kuczaj, S., Solangi, M.
The present study quantified the daily (short-term) and monthly (long-term) behavioural repertoires of three dolphins that participated in Dolphin Interaction Programs with paying guests. Behavioural data were collected over a 6-month period, with Dolphin Interaction Programs occurring daily...
Into the brains of whales
Contributor(s):: Simmonds, M. P.
Whilst studies on cetaceans have focused on a few populations of just a few species, various complex behaviours and social structures that support the notion that cetaceans should be regarded as intelligent animals have been revealed. The evidence to support this is reviewed here and is best...
Evaluation of different observational sampling regimes for use in zoological parks
Contributor(s):: Margulis, S. W., Westhus, E. J.
Observational sampling methods provide clearly-defined guidelines for collection and analysis of behavioral data. In some situations, use of formal sampling regimes may be impractical or impossible. A case in point is data collection conducted by animal care staff at zoological parks and aquaria....
Awareness of whale conservation status and whaling policy in the US - a preliminary study on American youth
Contributor(s):: Parsons, E. C. M., Rice, J. P., Sadeghi, L.
In 2008, a preliminary study was conducted to provide information on awareness of cetacean (whale, dolphin and porpoise) conservation issues and the US government's policy on whaling, in a test group of US university students (n=230). When given a list of whale species, 39% of the participants...
Behavior of dolphins towards adults and children during swim-with-dolphin programs and towards children with disabilities during therapy sessions
Contributor(s):: Brensing, K., Linke, K.
In recent years, dolphin-assisted therapy has become very popular and an increasing number of facilities worldwide offer therapy programs with dolphins. In contrast to other animal-assisted therapy programs, dolphins are not domestic animals; they are mostly caught in the wild and there are still...
