1. A climate migrant escapes its parasites

   When a species colonizes a new range, it can escape enemies found in its original range. Examples of enemy escape abound for invasive species, but are rare for climate migrants, which are populations of a species that colonize a new range due to climate-driven range shifts or expansions. The fiddler crab Minuca (= Uca ) pugnax is found in the intertidal salt marshes of the US east coast. It recently expanded its range north into the Gulf of Maine as a result of ocean warming. We tested the hypothesis that M. pugnax had escaped its parasite enemies. Parasite richness and trematode intensity were lower in populations in the expanded range than in populations in the historical range, but infection prevalence did not differ. Although M. pugnax escaped most of its historical parasites when it migrated northward, it was infected with black-gill lamellae (indicative of Synophrya hypertrophica ), which was found in the historical range, and with the trematode Odhneria cf. odhneri , which was not found in the historical range. To our knowledge, this is the first time that O. cf. odhneri has been reported in fiddler crabs. These results demonstrate that although M. pugnax escaped some of its historical parasites when it expanded its range, it appears to have gained a new parasite ( O. cf. odhneri ) in the expanded range. Overall, our results demonstrate that climate migrants can escape their enemies despite colonizing habitats adjacent to their enemy-filled historical range.

3. Environmental Health Threats to Latino Migrant Farmworkers

   null (Ed.)

   Approximately 75% of farmworkers in the United States are Latino migrants, and about 50% of hired farmworkers do not have authorization to work in the United States. Farmworkers face numerous chemical, physical, and biological threats to their health. The adverse effects of these hazards may be amplified among Latino migrant farmworkers, who are concurrently exposed to various psychosocial stressors. Factors such as documentation status, potential lack of authorization to work in the United States, and language and cultural barriers may also prevent Latino migrants from accessing federal aid, legal assistance, and health programs. These environmental, occupational, and social hazards may further exacerbate existing health disparities among US Latinos. This population is also likely to be disproportionately impacted by emerging threats, including climate change and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Latino migrant farmworkers are essential to agriculture in the United States, and actions are needed to protect this vulnerable population.

4. Accompaniment and Anthropology with Im/migrant Communities

   Whitney L. Duncan (March 2023, Society for Applied Anthropology Annual Meeting)

   This roundtable brings together engaged anthropologists working with im/migrant communities to explore the transformational potential of accompaniment as anthropological practice. Informed by decolonial and feminist critiques of anthropology, accompaniment troubles the boundaries of scholar-activist and academic-community member to address the broader social purpose of our anthropological work. We understand accompaniment as an ethical commitment to solidarity, to using our positions of relative privilege to help ameliorate suffering. The roundtable will serve as a collective conversation about the multivalent meanings of accompaniment with im/migrant communities and as a forum to imagine possibilities for caring, relational, and decolonial forms of ethnographic engagement.

5. Migrant Labor Supply Chains: Architectures of Mobile Assemblages

   https://doi.org/10.1177/09646639221080519  

   Silliman Bhattacharjee, Shikha (December 2022, Social & Legal Studies)

   This paper explores the potential for Assemblage Theory to supplement current approaches to studying labor migration in law and the social sciences. Based upon a study of women's migration for garment and domestic work in India, I lay out the labor supply chain assemblage (LSCA) as a framework for understanding how workers find employment across multi-site, dynamic trajectories. Migration into temporary employment requires workers to move between jobs on an ongoing basis. Accordingly, studying labor supply chains as fluid assemblages defined by labor market conditions, component elements, and various agents provides a methodology for analyzing frequent job searches, across recruitment geographies, that include a range of recruitment actors. By accommodating temporal, territorial, and relational analysis, this approach provides insight into how labor migration processes for migrant garment and domestic workers in India articulate with the development of markets, working conditions, and social hierarchies – including on the basis of gender and caste.
