Fidelity to foraging sites after long migrations.

Patterns of animal movement associated with foraging lie at the heart of many ecological studies and often animals face decisions of staying in an environment they know versus relocating to new sites. The lack of knowledge of new foraging sites means there is risk associated with a decision to relocate (e.g. poor foraging) as well as a potential benefit (e.g. improved foraging). Using a unique long-term satellite tracking dataset for several sea turtle species, combined with capture-mark-recapture data extending over 50 years, we show how, across species, individuals generally maintain tight fidelity to specific foraging sites after extended (up to almost 10,000 km) migration to and from distant breeding sites as well as across many decades. Migrating individuals often travelled through suitable foraging areas en route to their 'home' site and so extended their journeys to maintain foraging site fidelity. We explore the likely mechanistic underpinnings of this trait, which is also seen in some migrating birds, and suggest that individuals will forgo areas of suitable forage encountered en route during migration when they have poor knowledge of the long-term suitability of those sites, making relocation to those sites risky.

Mitigating Contemporary Trauma Impacts Using Ancient Applications.

The COVID-19 pandemic represents the most significant global challenge in a generation. Based on extant data from previous pandemics, demographic, occupational, and psychological factors have been linked to distress and for some vulnerable members of society. COVID-19 has added to the layers of grief and distress of existing trauma. Evidence-based frameworks exist to guide our individual and collective response to reduce the trauma associated with the experience of a pandemic. Pandemic and post-pandemic measures to ameliorate impacts require a multi-disciplined approach, central to which is community connectedness, resilience, and access to support. We advocate for the acceptance and broader application of Dadirri, a healing practice held by the Ngan'gikurunggurr and Ngen'giwumirri Aboriginal people of the Daly River region in the Northern Territory, Australia. This modality engages therapeutic phases that are comparable with other practiced trauma therapies. The demonstrated therapeutic outcomes from Dadirri can be attained through an individualistic or in a relational engagement context. This practice is accessible to all ages, is non-specific to gender and is suitable for people constrained in their mobility or limited by resources, pertinent in pandemic affected settings.
