Abstract:

Genetic conservation aims to apply genetic methods to deal with the maintenance, loss, and restoration of biodiversity, which overcame issues from traditional investigations. In this study, three case studies were presented to illustrate that integrating ecology, evolutionary and genetics analysis provided a more comprehensive information for conservation. Riparian is preferable areas for human settlements, and fish communities in the rivers therefore facing the threats from human activities. The metabarcoding of eDNA results clearly showed that accidentally and intentionally anthropogenic activities significantly influenced fish communities, and protect river habitat, limited human disturbances and enhancing fish stock should be considered for the conservation protection countermeasure and management. In the deep-sea ecosystem, conservation is an enormous challenge, because knowledge about and understanding of population structure and connectivity of deep-sea fauna decreases with increasing depth. Population and seascape genetics of 7 vulnerable marine ecosystems (VMEs) indicator taxa confirmed that factors related to currents explained their genetic structures, and these different patterns of population genetic structure and connectivity at a range of spatial scales indicate that flexible spatial management was required for the deep-sea conservation.
