Objectives: This paper outlines the unique culturally driven cyclical migration of Alaska Native (AN) Elders, distinct from previously described migration patterns in that Elders spend extended time in more than one community. We describe this Indigenous cyclical migration of AN Elders and its influence on their identity and later life health and well-being.
Methods: Interviews with 124 AN Elders were conducted across 5 regions of Alaska: Bristol Bay, Interior, Norton Sound, Aleutian Pribilof Islands, and Southcentral. Within this sample, 87 participants engaged in cyclical migration. Thematic analysis was employed to identify themes related to Elders' cyclical migration between rural and urban communities and the impact on their identity and later life health and well-being.
Results: We identified 2 distinct patterns of Indigenous cyclical migration-Elders living primarily in rural communities migrating to urban communities and Elders living primarily in urban communities migrating to rural communities. Elders engaged in these 2 patterns of cyclical migration to maintain cultural practices, access social, and health care services to maintain their physical health and well-being, and continue their community roles contributing to their AN Elder identity.
Discussion: This study builds upon existing migration theories by introducing a cyclical pattern uniquely driven by AN identity, culture, and traditional practices. Findings illustrate how AN communities can support Elders who experience cyclical migration patterns to ensure they age successfully in both locations. Future research should explore cyclical migration patterns among other Indigenous populations with migration histories.

The circadian clock genes are known important for kidney development, maturation and physiological functions. However, whether and how they play a role in renal regeneration remain elusive. Here, by using the single cell RNA-sequencing (scRNA-seq) technology, we investigated the dynamic gene expression profiles and cell states after acute kidney injury (AKI) by gentamicin treatment in zebrafish.

East, South, and Southeast Asia (together referred to as Southeastern Asia hereafter) have been recognized as critical areas fuelling the global circulation of seasonal influenza. However, the seasonal influenza migration network within Southeastern Asia remains unclear, including how pandemic-related disruptions altered this network. We leveraged genetic, epidemiological, and airline travel data between 2007-2023 to characterise the dispersal patterns of influenza A/H3N2 and B/Victoria viruses both out of and within Southeastern Asia, including during perturbations by the 2009 A/H1N1 and COVID-19 pandemics.

The timing of migration is fundamental for species exploiting seasonally variable environments. For ungulates, earlier spring migration is expected with earlier vegetation green-up. However, other drivers, such as access to agricultural farmland and variation in local conditions, are also known to affect migration.

The traditional narrative of the life cycle of migratory birds is that individuals perform long-distance movements between a breeding and a wintering site, but are largely resident at those sites. Although this pattern may apply to socially monogamous species with biparental care, in polygamous systems, the sex that only provides gametes may benefit from continuing to move and sample several potential breeding sites during a single breeding season. Such behaviour would blur the distinction between migration and breeding.

Temperate fishes often spawn in response to environmental cues, such as temperature, thereby facilitating larval emergence concurrent with suitable biotic and abiotic conditions, such as plankton blooms. Climatic changes may alter the reproductive phenology of spring- and autumn-spawning freshwater fish populations. Such effects may depend on the sensitivity of reproductive phenology to ambient temperatures.
