Lingula anatina is a brachiopod widely distributed in the western Pacific region. Even though L. anatina has been targeted for a number of biological studies, there is still limited information on intraspecific genetic variations of L. anatina. In this study, L. anatina specimens were collected from Korea and Vietnam, and complete mitochondrial genome (mitogenome) sequences were analyzed and compared with previous records. The total mitogenomes of L. anatina were 24,875 bp and 25,305 bp in size for Korean and Vietnamese specimens, respectively. Those mitogenomes are extraordinarily longer than the typical mitogenome size for an animal but shorter than the previous record from Yanagawa (Japan) for this species. The gene orders and the sizes of the protein-coding genes are also different from those for the Japanese specimen. Furthermore, the nonsynonymous (Ka) and synonymous (Ks) substitution rates in protein-coding genes (PCGs) were calculated to test the idea of evolutionary rate differences in mitochondrial genomes. The analyses showed relatively low Ka and Ks for the complete mitogenomes from Buan (Korea), Doson (Vietnam) and Yanagawa (Japan). The Ka/Ks ratio was less than 1 in comparisons of three localities, indicating the existence of purifying selection in this species. The phylogenetic analyses showed that L. anatina diverged among localities in the western Pacific region.

Abstract Background Increasingly, international health bodies frame public health measures, including tobacco control, in the context of human rights (HR). It is unclear how prevalent is the connection between human rights and tobacco control within global health governance. This paper describes the inclusion of HR in tobacco control governance, and the inclusion of tobacco control in HR treaty oversight. We depict the current reach of HR’s normative influence in framing the tobacco epidemic in global, regional, and country-specific contexts. Methods We reviewed documents (agenda, reports) from 2010 to 2019 from the World Health Assembly (WHA); the WHO Western Pacific Regional Committee Meetings (RCM); the WHO Framework Convention on Tobacco Control (WHO FCTC) Conferences of the Parties (COP); and documents provided by Pacific Island Countries party to, or by committees overseeing, HR treaties. We purposively selected the Western Pacific Region, and Pacific Island Countries specifically, to represent countries of varying populations, capacities, and governance. Results Tobacco control and HR are infrequently mentioned together in the WHAs, and primarily in only one COP. Tobacco control is mentioned in 47 HR treaty committee documents for Pacific Island Countries, mostly under the Convention of the Rights of the Child recognizing or calling for ratification of the WHO FCTC. HR and tobacco control are connected in WHO Western Pacific RCM, particularly through their two most-recent action plans adopted by respective RCMs. Discussion Tobacco control as a HR concern is gaining traction within HR treaty bodies, at least with respect to children’s health in the Western Pacific Region. Conclusion Globally, HR is just emerging as an influence in global health governance for tobacco discussions. Within the Western Pacific Region however tobacco control is seen by some authorities as a HR issue. Similarly, to HR experts, tobacco control is becoming important to how Pacific Island Countries fulfill their treaty obligations, suggesting tobacco control advocates might explore these mechanisms to further influence the development of strong tobacco control measures to implement the WHO FCTC.
