This paper reviews some of the studies on Black Sea bottlenose dolphins (Tursiopstruncatus ponticus) conducted during the 15 years since the establishment of the International Laboratory for Dolphin Behaviour Research (ILDBR) located at the semi-natural Dolphin-Reef (Eilat, Israel) tourist facility. We describe how this site overcomes many of the problems that characterize captivity sites, and how our research gains important insight into dolphin behavior, which is difficult to obtain – if at all – in the study of wild populations.

Behavior was observed in the dive tank for 5 min, immediately followed by 5 min in the light/dark plus maze.

Further, behavior of zebrafish exposed for 3 min to 25 mg/L nicotine, desipramine, chlordiazepoxide, yohimbine, 100 mg/L citalopram, 0.05% DMSO, or 0.5% ethanol was compared to controls.

In cetaceans reproduction takes place completely in water. From courtship and mating tocalf weaning, every step of the reproductive process occurs under the water’s surface. This complicates data acquisition in wild populations, making captive observations a useful complement to wild studies. By allowing close examination of phenomena, studies in captive environments are able to collect long-term data on known subjects, and sample, in detail, complete behavioural sequences while monitoring physiological or acoustic patterns. Studies of reproduction in bottlenose dolphins (Tursiops truncatus) were initiated at Rimini Delfinario (Italy) in 1995. Four bottlenose dolphin births (in 1995, 1997, 2003 and 2007) have occurred since the start of this research. Due to evidence suggesting that mother and calf associations are closest in the first year of the calf’s life, mothers and calves were studied from birth to the end of the first year. Beginning in 1997, studies encompassed the behaviour and physiology of dolphin mothers during gestation. Here, we report results of interdisciplinary studies of reproductive processes in bottlenose dolphins, including aspects of behaviour, physiology, endocrinology, and acoustics. In an effort to reduce the potential for bias brought about by invasive sampling, we investigated methods of sampling expired air from the dolphin’s blow hole as a means of monitoring steroid hormone levels. In summary, our research combines an interdisciplinary network with specialized professional alliances and offers a potentially crucial approach to the biological aspects of reproduction. At the same time, research findings presented here aim to help bridge the gap existing between captive and wild studies in favor of acommon aim of conservation biology.","PeriodicalId":39712,"journal":{"name":"International Journal of Comparative Psychology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2010-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70620189","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These studies include descriptive accounts, both qualitative and quantitative, of behavior-in-context in naturally-occurring and quasi-experimental settings, especially involving the micro-analysis of video. To unify this piecemeal but burgeoning literature, “cognition” is taken as embodied, largely visible, and distributed across physical and social environments. Its study involves documenting the adaptation of behavior to changing conditions, especially in ontogeny, tool-use, and social discourse. The studies selected for this review focus on the cognitive complexity that is apparent in the versatility, the hierarchical organization, and the long-term patterning of such behavioral adaptations. Versatility is seen, for example, in the substitution of different acts or objects into established routines, in the size and flexibility of action repertoires that enable variably configured and sequenced performances, and in the marked occurrence of individual differences. Hierarchical organization is seen in the substitution or iteration of a subroutine that fails to disrupt its larger routine, in the simultaneous embedding of one social interaction within the frame of another (as in “social tool” use), and in the insertion of a novel or borrowed subroutine as a tactical response, especially one that temporarily redirects an animal‟s trajectory. The complexity apparent in long-term patterning includes tracking and making selective use of multiple histories (e.g., concerning kinship, rank, etc.) whose predictions and tactics may vary, responding to “market” values that change with ecological and social factors, and exploiting traditions of practice which provide social and material resources that shape engagement and learning. While this literature includes far more primate than cetacean examples, the primate work offers helpful suggestions for settings, issues, and techniques that could be adapted to the sensori-motor, ecological, and social constraints on cetacean cognition. The array of observations reviewed illustrate the utility across species of scoring such parameters as displays of attention in multiple modalities, abrupt trajectory changes, the complementarity and contingency of actions, and the resiliency of sequences, to help identify the media that matter in a given cognitive ecology. Systematic micro-analyses, in conjunction with long-term relational data that track changes in affordances and coordination, make such observational approaches a viable and valuable addition to the study of comparative cognition.","PeriodicalId":39712,"journal":{"name":"International Journal of Comparative Psychology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2010-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70620473","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
