Communication styles used during divorce-related conversations may negatively influence the quality of parent-child relationships. Researchers have not examined how communication styles used in divorce-related communications affect parent-offspring relationships in same-sex parented families. The purpose of this generic qualitative study was to examine offspring perceptions of how divorce-related communication styles affected relationships between the children and their same-sex parents. The research question for this study addressed how the perceived communication styles of same-sex parents in divorce-related conversations influence the parent-offspring relationship. Principles from communication privacy management theory provided the conceptual framework. Two 21-year-old females whose same-sex parents dissolved their relationships participated in the study. Data were collected using semistructured interviews and a demographic questionnaire. Thematic content analysis was used to analyze the data. Findings indicated that same-sex parent-child relationships were negatively impacted when same-sex parents were ambiguous in their communication or triangulated their children by forcing them to send negative messages between their parents. Findings also indicated that same-sex parent-offspring relationships were positively impacted when same-sex parents effectively communicated with their offspring during divorce-related conversations. Findings may provide information to professionals and same-sex parents regarding the importance of communicating effectively with their offspring during divorce-related conversations.

New analytical and technological tools have the potential to yield unprecedented insights into the life histories of migratory species. I used Bayesian population models and Global Positioning System-acceleration tracking devices to understand the demographic mechanism and likely drivers underpinning the Greenland White-fronted Goose (Anser albifrons flavirostris) population decline. I used a 27-year capture-mark-recapture dataset from the main wintering site for these birds (Wexford, Ireland) to construct multistate models that estimated age- and sex-specific survival and movement probabilities and found no sex-bias in emigration or ‘remigration’ rates (chapter 2). These formed the foundation for an integrated population model, which included population size and productivity data to assess source-sink dynamics through estimation of age-, site-, and year-specific survival and movement probabilities, the results of which suggest that Wexford is a large sink and that a reduction in productivity (measured as recruitment rate) is the proximate demographic mechanism behind the population decline (chapter 3). Low productivity may be due to environmental conditions on breeding areas in west Greenland, whereby birds bred at youngest ages when conditions were favourable during adulthood and the breeding year (chapter 4), and possibly mediated by links with the social system, as birds remained with parents into adulthood, forfeiting immediate reproductive success, although a cost-benefit model showed the ‘leave’ strategy was marginally favoured over the ‘stay’ strategy at all ages (chapter 5). Foraging during spring does not appear to limit breeding, as breeding and non-breeding birds did not differ in their proportion of time feeding or energy expenditure (chapter 6). Two successful breeding birds were the only tagged individuals (of 15) to even attempt to nest, suggesting low breeding propensity has contributed to low productivity. Although birds wintering in Ireland migrated further to breeding areas than those wintering in Scotland, there were no differences in feeding between groups during spring migration (chapter 7). These findings suggest that Greenland White-fronted Geese are not limited until arrival on breeding areas and the increasingly poor environmental conditions there (chapter 8). More broadly, these findings demonstrate the application of novel tools to diagnose the cause of population decline.
