Benefit of cognitive environmental enrichments on social tolerance and play behavior in bottlenose dolphins (Tursiops truncatus)

Social tolerance is an essential feature of social life that can determine the good functioning of a group of animals. Play behaviors, like social play and playing with objects, are frequently associated with positive emotional and welfare states. As a...

Know when you are on a break: Effects of predictable breaks on bottlenose dolphins Tursiops truncatus behaviours

Under human care, dolphins' activities are alternated with moments of breaks that should allow them to behave as they want. However, scheduled activities such as training, feeding and playing with objects can affect dolphins' behaviours during breaks. Specifically, dolphins perform...

Using anticipatory behavior as preference test in the bottlenose dolphin (Tursiops truncatus)

The preference tests have made a great contribution to promoting animal welfare. However, they are not always easily applicable and have some criticalities. Recently the anticipatory behavior has been used to detect the animals' preference. In this study, we attempted...

A fast technique to induce and measure anticipatory behavior in bottlenose dolphins (Tursiops truncatus)

Anticipatory behavior describes the actions taken to prepare for an upcoming event. It is considered a promising tool for welfare assessment, but it is not fully applied in zoos and other facilities. This is probably due to the need to...

Social behaviors modulate bottlenose dolphins’ (Tursiops truncatus) breathing rate

Breathing frequency is a non-invasive physiological measure that brings valuable information on the bottlenose dolphins' internal state and behaviors. When combined with behavioral observations, it helps to better understand and interpret relevant behaviors. The present study aimed to investigate some...

Testing use of the first multi-partner cognitive enrichment devices by a group of male bottlenose dolphins

Alliance formation plays a crucial part in male dolphins' lives. These partnerships may last for decades or even for a lifetime; thus, partner choice and the maintenance of these relationships are both considered key components of alliance formation. In our...

Return of sound production as a biomarker of bottlenose dolphin emergence from anesthesia

(1) Background: When a human or animal is recovering from general anesthesia, their medical team uses several behavioral and physiological parameters to assess their emergence from the unconscious state to complete wakefulness. However, the return of auditory and acoustic behaviors...

A system for monitoring acoustics to supplement an animal welfare plan for bottlenose dolphins

Animal sounds are commonly used by humans to infer information about their motivations and their health, yet, acoustic data is an underutilized welfare biomarker especially for aquatic animals. Here, we describe an acoustic monitoring system that is being implemented at...

Environmental enrichment factors associated with the activity level of bottlenose dolphins under professional care

Environmental enrichment can be used to improve the welfare of dolphins in zoos and aquariums. Bottlenose dolphins under professional care are typically provided with a range of enrichment that has a variety of features and levels of complexity at various...

Euthanasia complications in non-domestic species

There are very few studies describing euthanasia complications in non-domestic species. The goal of this study was to survey veterinarians to determine what complications may commonly occur during the euthanasia of non-domestic species. An online survey was sent to seven...
