Available in PDF, EPUB and Kindle. Book excerpt: This book concentrates on the marine mammalian group of Odontocetes, the toothed whales, dolphins, and porpoises. In 23 chapters, a total of 40 authors describe general patterns of ethological concepts of odontocetes in their natural environments, with a strong bent towards behavioral ecology. Examples are given of particularly well-studied species and species groups for which enough data exist, especially from the past 15 years. The aim is to give a modern flavor of present knowledge of ethology and behavior of generally large-brained behaviorally flexible mammals that have evolved quite separately from social mammals on land. As well, the plight of populations and species due to humans is described in multiple chapters, with the goal that an understanding of behavior can help to solve or alleviate at least some human-made problems.

This book was released on 2015 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Little is known about the specific behavioral exchanges that occur on a day-to-day basis between dyads of bottlenose dolphins (Tursiops truncatus). This thesis assesses proximity between dyads (~ 2 meters) and the proportion of time that is spent in either an affiliative, agonistic, or socio-sexual context within age/sex pairings of dolphins in order to better understand the nature of social relationships in this species. Observations of bottlenose dolphins housed at the Roatan Institute of Marine Sciences, collected in 2010, provided 10.5 hours of underwater footage for assessment of association coefficients and proportions of interactions. These data suggested similar patterns to previous studies on bottlenose dolphin association patterns and interactions. Mother-calf dyads were found to share the highest coefficients of association, followed by male-male, female-female, and male-female dyads. Four classes of association coefficients were defined for the population: low, medium, medium-high and high. Regardless of which class dyads fell into, affiliative behavior was the most prevalent context recorded, followed by agonistic, and then socio-sexual contexts. This same pattern was also found regardless of which age/sex categories the dyads were placed. This study is the first to quantitatively assess association patterns with affiliative, agonistic, and socio-sexual behaviors in this species concurrently and reveals that the social relationships of these dolphins are predominately affiliative in nature. Furthermore, the patterns of social relationships observed appear to be consistent with sex-specific reproductive strategies. --Page ii.

Download or read book A Systematic Approach to Measuring the Social Behavior of Bottlenose Dolphins written by Amy Samuels and published by . This book was released on 1996 with total page 536 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research on cetacean social behavior is in transition from descriptive natural history to quantitative analyses. To expedite this change, an intellectual history of the field is provided, from the early whaler-naturalists to oceanarium observations, whale carcass studies, pseud-scientific inquiries into human-dolphin communication, and longterm field studies. Subsequent chapters illustrate use of systematic methodologies to better understand bottlenose dolphin social relations. Samuels and Gifford adapted a quantitative technique from primate behavioral research to study agonism among captive dolphins. Males were dominant to females; females had stable, age-ordered dominance relations; and two males had a changeable dominance relationship. Sex differences in dominance relations generated predictions about the behavior of wild dolphins that can be tested using this technique. Samuels, Richards and Mann investigated the association of wild juvenile dolphins with their mothers after weaning. Juvenile daughters continued to associate with their mothers, whereas juvenile sons rarely did so even though they remained in the same area as their mothers. Sex differences in juvenile association patterns appeared to foreshadow adult social networks. Samuels and Spradlin applied quantitative behavioral techniques to evaluate dolphin behavior in Swim-With-Dolphins programs. Two program types were defined by presence ('Controlled') or absence ('Not-Controlled') of explicit trainer regulation of dolphin-with-human interactions. In 'Not-Controlled' programs, the behavior of dolphins and humans threatened human safety and dolphin well-being, whereas 'Controlled' programs effectively minimized behaviors that posed risk to dolphins or humans.

This book was released on 2013 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: This project examines the social functions of mouthing behaviors in bottlenose dolphins (Tursiops truncatus). The Roatan Institute for Marine Sciences (RIMS) houses dolphins which are captive but in a natural habitat. The twenty-six dolphins are used in human interactions, but for the rest of their time they are allowed to roam naturally. These dolphins make it possible to examine natural social behavior in a captive setting. The following study examines video data of these dolphins obtained by Dr. Stan Kuczaj in 2009. Behavior of the dolphins in these videos was recorded, the primary focus being mouthing behaviors. There are three commonly observed mouthing behaviors: open mouth, mouthing, and biting/raking. This project aims to examine how often and in what context mouthing behavior occurs, which has not previously been widely studied. This will be examined in three main questions: 1. How often does each type of mouthing behavior occur? 2. What sex and age of dolphins are doing the mouthing behavior? 3. In what contexts does the mouthing behavior occur? I expect to find that open mouth is the most often mouthing behavior performed in a wide variety of social situations. Due to strong bonds between males and male-male dominance displays, I expect males to mouth males more often than females. I expect that juveniles will generally perform mouthing behaviors most often and to other juveniles. I expect mouthing behaviors will also be observed commonly in general contexts such as orient. Dolphins use social signals in a complex social life and I predict mouthing behaviors are an integral part of many social situations of bottlenose dolphins.--P. iii.

This book was released on 2006 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wild bottlenose dolphin populations display societal structures characterized by numerous and frequent changes in group composition, complex social relationships, and high levels of cooperation. Similar societies are observed in the chimpanzee, a species whose conflict and reconciliation behavior patterns have been well documented. While environmental constraints inhibit captive dolphin social relationships, interspecific cultural similarities suggest a need for examination of delphinid conciliatory tendencies. The social behavior of seven bottlenose dolphins retained at the Indianapolis Zoo was videotaped over an eight-week period to determine the presence and effects of gender and age on the frequency of conflict, reconciliation, consolation, and non-conflict interactions.

This book was released on 2016 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bottlenose dolphins (Tursiops truncatus) have been documented to possess personality traits that remain consistent over time (Highfill & Kuczaj, 2007) and across contexts (Kuczaj, Highfill, & Byerly, 2012). Such individual differences are thought to play an important role in various social contexts such as hierarchical dominance (Highfill & Kuczaj, 2010). The present study investigated the relationship between personality and social rank within a captive group of bottlenose dolphins housed at the Roatan Institute for Marine Science (RIMS). Social rank was established using questionnaires distributed to the RIMS experienced staff. Personality traits were derived from behavioral coding using context-specific correlational matrices. The traits were then correlated to each dolphin's social rank position. The results suggest that a relationship between individual personality and social status is present, but complex. Traits that emerged exhibited sexdifferences. Of the 12 factors found for the males, sexual (DID), contact seeking (DIO), and camaraderie (DID) were significantly related to social rank. For the females, only factors playful (DIO) and evasive (DIH) were significantly related to social rank. Individuals ranked at both extremes of the hierarchy (highest and lowest) seem to exhibit a more correlative relationship between personality and social status. However, other factors appear to play an important role in this relationship for middle-ranked dolphins. These results suggest that factors such as age, strength of associations between individuals, maternal style, and interactions between the male and female hierarchies all influence how personality is expressed in different contexts. --Page ii.

Download or read book Behavioral Development of Free ranging Juvenile Bottlenose Dolphins Tursiops Truncatus in Sarasota Bay Florida written by Katherine Anne McHugh and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The juvenile life stage is both fragile and formative for young animals learning to navigate complex social and ecological environments. Bottlenose dolphins (Tursiops truncatus) are particularly interesting from this perspective as they have complex fission-fusion social systems and a prolonged developmental period, both while dependent on their mothers and as independent juveniles. During this period, they shift from associating in mixed-sex groups of young animals towards sexually segregated male alliances and female networks as adults. This project used bottlenose dolphins at a long-term study site as a model system to explore behavioral development, provide insights into the functional significance of groups, and examine the effects of environmental disturbance on the behavior of newly-independent animals. To achieve this, I combined long-term sighting data from the resident dolphin community in Sarasota Bay, FL with new information on activity patterns, habitat use, ranging behavior, and social associations collected through focal animal behavioral observations on 27 individuals during 2005-2008. This research is one of the first studies of independent juvenile behavior in cetaceans and provides a more comprehensive understanding of behavior throughout life history for long-lived species with extended immature periods. Chapter One provides background information on juvenile behavior, social complexity, and the study population. In Chapter Two, I examine social and behavioral development of juvenile dolphins, focusing on activity budgets and social associations. This chapter highlights individual variability in social development, sex- and age-related differences in juvenile behavior, and continued maternal influences on sociality post-independence. In Chapter Three, I explore juvenile dolphin habitat selection, ranging behavior, and natal philopatry. This chapter documents seasonal differences in behavior, changes to ranging patterns coincident with life-history transitions, and maternal transmission of ranging and habitat use patterns. Both chapters discuss findings relative to three hypothesized benefits of groups: predator protection, foraging efficiency, and socialization. Finally, in Chapter Four, I investigate how large-scale natural disturbance events, in the form of severe harmful algal blooms, affect dolphin behavior. This chapter provides evidence that red tides affect activity budgets, sociality, and ranging behavior of inshore dolphins and links these effects to underlying changes in resource availability during blooms.

Download or read book Marine Mammal Welfare written by Andy Butterworth and published by Springer. This book was released on 2017-06-19 with total page 625 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine mammals attract human interest – sometimes this interest is benign or positive – whale watching, conservation programmes for whales, seals, otters, and efforts to clear beaches of marine debris are seen as proactive steps to support these animals. However, there are many forces operating to affect adversely the lives of whales, seals, manatees, otters and polar bears – and this book explores how the welfare of marine mammals has been affected and how they have adapted, moved, responded and sometimes suffered as a result of the changing marine and human world around them. Marine mammal welfare addresses the welfare effects of marine debris, of human traffic in the oceans, of noise, of hunting, of whale watching and tourism, and of some of the less obvious impacts on marine mammals – on their social structures, on their behaviours and migration, and also of the effects on captivity for animals kept in zoos and aquaria. There is much to think and talk about – how marine mammals respond in a world dramatically influenced by man, how are their social structures affected and how is their welfare impacted?
