Seasonality of Social Behaviour Among Immature Belugas (Delphinapterus leucas) in Managed Care

Belugas ( Delphinapterus leucas ) in managed care have been reported to show seasonal variation in socio-sexual behaviour, hormone levels and respiration rates; however, little is known about the social interactions of wild belugas when they are not in summer, near-shore congregations. To better understand if belugas show seasonal variation in social interactions, this study recorded the behaviour of 10 belugas (five females, five males, ranging from birth to 10 years of age) housed in managed care. Social interactions typically peaked in the summer months but persisted at very low levels during the rest of the year. Sea - sonal variation was most dramatic for socio-sexual behaviour but was generally mirrored in pattern by agonistic and affiliative interactions. Subjects closer to maturity displayed more seasonal variation than younger subjects, and males displayed more seasonal variation compared to females. The peak in social interactions found in this study aligns rather closely with wild belugas’ sum - mer, near-shore congregations, where belugas have increased opportunities for socializing. Although belugas in managed care do not experience a seasonal change in habitat, they do show seasonal changes in social behaviour, which are likely driven by seasonal fluctuations in hormone levels. It is therefore expected that wild beluga populations would show similar behavioural pat - terns if they were observed throughout the remainder of the year. This research has applications for belugas in managed care and may provide a framework for understanding the social behaviour of wild belugas

Effects of Human-Dolphin Interactions on Tourist Knowledge of and Attitudes Toward Dolphins

Human-wildlife interactions have been shown to positively impact tourist beliefs and actions in relation to wildlife and the environment. The purpose of this study was to explore guest beliefs and perceptions about dolphins and dolphin programs before and after participating in human-dolphin interactions (HDI). We surveyed 142 guests participating in a self-selected HDI located in a natural lagoon facility at The Roatán Institute for Marine Sciences in Sandy Bay Roatán, Honduras. Of the 142 survey respondents, 130 completed the survey fully, and 28 of those 130 also completed a two-week follow-up survey. The results indicated that the guests maintained pre-existing positive attitudes towards dolphins, learned new information, and reported feeling connected with nature following their HDI experiences. The HDI experience format resulted in few differences in participant responses, suggesting that interactive programs maintained existing attitudes while subtly shaping beliefs about human-animal interactions

The influence of background music and narrative setting on anthropomorphic judgements of killer whale (Orcinus orca) emotional states and subsequent donation behavior.

Animal documentary films such as Blackfish, considered nonfiction accounts of reality, nonetheless use rhetorical devices to engage viewers and shape their emotional experience for maximum effect. Such devices can also influence attitudes and alter behavior. In animal documentaries, anthropomorphic impressions of the animals by audiences are key. Using general population samples in the US, three online experiments assessed the influence of background music and narrative setting on how viewers emotionally appraised the emotional state of a killer whale (Orcinus orca) and subsequently donated to causes affiliated with killer whales. While happy music led to perceptions of a happy whale, sad music led to perceptions of a sad whale. mediation analyses showed that these perceptions indirectly influence donation behavior, via beliefs about the killer whale's welfare and wellbeing. Analyses also indicated that the highest donation amounts towards killer whales were elicited from footage depicting a killer whale in the wild, with sad background music. These findings highlight the potential power that animal and nature documentaries have over viewers, which, when combined with human tendencies toward anthropomorphism, can have significant influence on conservation attitudes and behavior
