Dear Marmamm peeps

Happy to share with a recent article that we published using primary data
and open access gene sequences on dugongs.

Please find the article here.
Mitochondrial phylogeography reveals high haplotype diversity and unique
genetic lineage in Indian dugongs (Dugong dugon) - Srinivas - - Aquatic

1. India plays a significant role in dugong conservation by having the
largest population within South Asia. The status of dugongs in India is
largely unknown due to a paucity of reliable ecological data. This study
generated mitochondrial control region sequences from 10% of dugong
individuals from existing populations within India. Furthermore, data
generated in this study were compared with the global data to assess
genetic lineages, population structure, and genetic diversity of Indian
populations. 2. Multiple analyses suggest that the Indian dugong
populations are part of a single genetic cluster, comprising South Asia,
North-west Indian Ocean, and South-west Indian Ocean populations. Despite
small population size, they retain high genetic diversity with unique
mitochondrial DNA haplotypes within South Asia. Within India, novel
haplotypes are observed from all dugong habitats sampled, with overall high
haplotype diversity (0.85 ± 0.04) but low nucleotide diversity (0.005 ±
0.001). Indian populations exhibit genetic differentiation with higher
within-population variance (63.41%) than among populations (36.59%). Two of
the haplotypes observed in India are shared with Sri Lanka, implying
genetic connectivity between these populations. 3. The genetic data from
Indian dugong populations provide critical insights into the identification
of dugong corridors and important dugong conservation zones in India. We
suggest site-specific interventions, including the creation of new marine
protected areas and boundary reorganization and expansion of other existing
protected areas, to ensure population connectivity. In addition,
simultaneous efforts towards seagrass meadow restoration, reduction of
dugong mortalities, and community participation in dugong conservation are
recommended for population recovery of this threatened marine herbivore.
