Site Fidelity and Association Patterns of Bottlenose Dolphins (<i>Tursiops truncatus</i> in the Mississippi Sound
… current study examined the site fidelity and association patterns of a community of 678 wild bottlenose dolphins (Tursiops truncatus) in the Mississippi Sound (Sound) over a three-year period (May 2004 - April 2007). Using photoidentification techniques, 74% (n = 498) of the identified …

Characterization of Association Patterns of Coastal Migratory Bottlenose Dolphins, <i>Tursiops truncatus</i>, in the Nearshore Waters of Virginia Beach, Virginia
… data from 1994 to 1999 to describe association patterns of bottlenose dolphins in the nearshore waters of Virginia Beach, Virginia. Bottlenose dolphins are present seasonally (late April until early November) in these waters and individuals are considered to be members of the North …

The Nature of Social Relationships in Bottlenose Dolphins (<i>Tursiops truncatus</i>): Associations and the Role of Affiliative, Agonistic, and Socio-Sexual Behaviors
… 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 …

Kernel-based association measures
Measures of associations have been widely used for describing the statistical relationships between two sets of variables. Traditional association measures tend to focus on specialized settings (specific types of variables or association patterns). Based on an in-depth summary of existing measures, …

Life History Parameters and Social Associations of Female Bottlenose Dolphins (Tursiops Truncatus) in North Carolina, USA
… anthropogenic disturbance or a natural change. Association patterns between and among these known females revealed relationships that have persisted for more than a decade. Most association patterns of the female dolphins in this area are long-term casual acquaintances which are evident in the …

Effects of fall orphaning on white-tailed deer fawns
… 2) the location of home ranges, and 3) the association of fawns with other deer. Twenty-one tagged fawns were orphaned in the fall by immobilizing and removing their mothers. Eighteen fawns were selected as controls. Data were recorded from July 1973 through March 1974, and included the …

A systematic approach to measuring the social behavior of bottlenose dolphins
… 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 …

An analysis of the process of association between Turkey and the European Community in the context of European integration and cooperation
This study is an attempt to analyze the Association process between Turkey and the European Community (the EC). In other words, it is a process of interaction between two actors within an institutionalized and formal association system. One is a state and the other is a sui generis organization …

Identifying dryinidae (hymenoptera) - auchenorrhyncha (hemiptera) host associations using phylogenetics
… host taxonomy and habitat, for explaining host association patterns. The number of species represented by larval samples was conservatively estimated by integrating genetic distances with natural history data. Host identification revealed 70 new dryinid-host associations, adding Eurybrachidae as …

Gender Differences in Rate and Associations of Attention Problems: Effects of Informant, Age, and Referral Status
… prevalence rate of Attention Problems and the associations with Attention Problems were not moderated by age or referral status.</p> <p>The data suggested that parents and teachers may not be fully aware of Attention Problems being experienced by females. This highlights the importance of …

Fission-Fusion Dynamics in Spider Monkeys in Belize
… chimpanzees (Pan) are known for their more fluid association patterns. These species have been traditionally described as living in fission-fusion societies, because they range in subgroups of frequently changing size and composition, in contrast with the more typical cohesive societies. In recent …

Social patterns in knowledge evolution and health policy
… this thesis analyzes and discusses social patterns in knowledge evolution and health policy. Knowledge can be considered to be a network of interconnected concepts, hence, understanding its latent topological structure can reflect many facts about the evolution of knowledge. Here, we study …

Same-Sex Socio-Sexual Interactions Among a Group of Captive Bottlenose Dolphins (<i>Tursiops truncatus</i>)
… these interactions, a longitudinal study of the patterns of association and the dynamics of initiator/recipient role exchange was conducted. Underwater video footage of a colony of bottlenose dolphins housed at the Roatan Institute for Marine Sciences (RIMS), collected between March of 2010 and …

Integration of multi-omic data and neuroimaging characteristics in studying brain related diseases
… different designs and directions from genomewide associations to studying the complex interplay between genetics and structural connectivity of a wide range of brain-related diseases. Nevertheless, such combinations of heterogeneous, high dimensional and inter-related data has introduced new …

Molecular studies on the taxonomy, host-associations and viruses of the Diplodia-like anamorphs of the Botryosphaeriaceae
… concentrated on their taxonomy, host associations and mycovirus infections associated with them. Diplodia pinea sensu lato represents a species complex of highly similar morphological types that mainly infect Pinus spp., world-wide. The species complex includes what have in the past …

Spatial distribution of canopy gaps in a tropical forest landscape and its influence on the tree community
… tools that allow measurement of disturbance patterns at fine spatial scale (Chambers et al. 2009). In old growth tropical forests, the creation of canopy gaps by one or multiple tree falls is one of the main causes of disturbance and thus potentially one of the main drivers of forest dynamics …

Behavioural ecology of Irrawaddy, Orcaella brevirostris (Owen in Gray, 1866), and Indo-Pacific humpback dolphins, Sousa chinensis (Osbeck, 1765), in northeast Queensland, Australia : a comparative study
… indicating strong concordance in the utilization patterns of shared areas by both species. Despite considerable overlap and concordance in space use patterns, Irrawaddy and humpback dolphins showed different habitat preferences. Within their representative range Irrawaddy dolphins preferred …
