The frontier of environmental DNA analysis: Challenging unresolved problems
Organizer:
Masayuki K. Sakata (Hokkaido University)
Environmental DNA analysis is widely used in biodiversity research. It is not only used to detect species, but also to estimate biomass, genetic diversity and reproductive behavior. However, there are still many unresolved problems in environmental DNA analysis, both in basic and applied aspects. In this session, we would like to introduce approaches and the latest research on these unresolved problems, and discuss the challenges, applicability and prospects of this method.

Organized Session2:
Frontiers in eDNA-based migratory fish studies
Organizer:
Tetsu Yatsuyanagi (FSERC, Kyoto Univ.), Hitoshi Araki (Research Faculty of Agriculture, Hokkaido Univ.)
Many migratory fish are not only useful fisheries species, but also play an important role in nutrient cycling and biodiversity maintenance through migration between ecosystems. Migration patterns are very diverse, and there are many species for which we do not yet have a full understanding of their migratory patterns and how they should be conserved. It has been difficult to track migratory fish throughout their lives because of the flexibility of their habitat, but since the advent of environmental DNA methods, many migratory fish studies have been reported that take advantage of these characteristics. On the other hand, there are still many challenges in elucidating the ecology of migratory fish through their complex life histories. In this program, we will introduce the latest research on various migratory fishes and discuss the usefulness of this method, its challenges, and prospects for future studies.
