Aims and Objectives: This discursive paper provides a call to action from an international collective of Indigenous nurse academics from Australia, Canada, Aotearoa New Zealand and the USA, for nurses to be allies in supporting policies and resources necessary to equitably promote Indigenous health outcomes., Background: Indigenous Peoples with experiences of colonisation have poorer health compared to other groups, as health systems have failed to address their needs and preferences. Achieving health equity will require leadership from Indigenous nurses to develop and implement new systems of care delivery. However, little is known about how Indigenous nurses influence health systems as levers for change., Design: A Kaupapa Māori case study design., Methods: Using a Kaupapa Māori case study methodology, coupled with expert Indigenous nursing knowledge, we developed a consensus on key themes. Themes were derived from three questions posed across the four countries. Themes were collated to illustrate how Indigenous nurses have provided nursing leadership to redress colonial injustices, contribute to models of care and enhance the Indigenous workforce., Results: These case studies highlight Indigenous nurses provide strong leadership to influence outcomes for Indigenous Peoples. Five strategies were noted across the four countries: (1) Indigenous nationhood and reconciliation as levers for change, (2) Indigenous nursing leadership, (3) Indigenous workforce strategies, (4) Development of culturally safe practice and Indigenous models of care and (5) Indigenous nurse activism., Conclusions: In light of 2020 declared International Year of the Nurse and Midwife, we assert Indigenous nurses' work must be visible to support development of strategic approaches for improving health outcomes, including resources for workforce expansion and for implementing new care models., Relevance to Clinical Practice: Curating strategies to promote Indigenous nurse leaders around the world is essential for improving models of healthcare delivery and health outcomes for Indigenous Peoples., (© 2021 The Authors.

Introduction: Indigenous Peoples are experiencing the ongoing effects of colonization. This phenomenon, historical trauma (HT), helps to address the current ill-health disparity. Aim of this scoping review was to identify sources of evidence available to understand the impact of HT on Indigenous young peoples. Method: A scoping review was conducted on available evidence-based literature. Article quality was assessed using validated quality appraisal tools. Synthesis was conducted with predefined levels of impact. Results: Consistent with the literature, the themes and levels of impact were interrelated. Despite this, studies predominately reported a singular focus with limited discussion of protective factors. Discussion: HT continues to have a profound impact on Indigenous young peoples across Canada, Australia, New Zealand, and the United States. Protective factors for HT were evident within Indigenous research designs. Future research should ensure a multilevel focus to explore intergenerational strength and how this influences culturally congruent health care.

To ensure energy demands for reproduction are met, it is essential that marine birds breed during periods of peak food availability. We examined associations of the breeding chronology of common murres (Uria aalge) with the timing of the inshore arrival of their primary prey, capelin (Mallotus villosus) from 1980 to 2006 across a period of pervasive change in the Northwest Atlantic ecosystem. We also assessed the influence of ocean temperature and the North Atlantic Oscillation (NAO; an index of winter climate and oceanography) on these interactions. We found a lagged linear relationship between variations in murre breeding chronology and the timing of capelin arrival in the previous year. On a decadal level, we found a non-linear threshold relationship between ocean temperature and the timing of capelin arrival and murre breeding. Centennially anomalous cold water temperatures in 1991 generated a marked shift in the timing of capelin spawning inshore and murre breeding, delaying both by more than 2 weeks. By the mid-1990s, ocean temperatures returned to pre-perturbation levels, whereas the temporal breeding responses of capelin and murres were delayed for a decade or more. Oceanographic conditions (temperature, NAO) were poor predictors of the timing of capelin arrival inshore in the current year compared to the previous one. Our findings suggest that knowledge of the timing of capelin availability in the previous year provides a robust cue for the long-lived murres, allowing them to achieve temporal overlap between breeding and peak capelin availability.
