| Outline of Research at the Start |
The present project proposal aims to address 3 main general scientific questions (SQ):
SQ1- What is the seasonal variability of prokaryotes and how does this correlates with site specific land
uses and hydrological regimes?
SQ2- What are the prokaryote gene expression patterns under RSP events?
SQ3- What is the environmental risk at each of the areas affected by different land use?
|
| Outline of Final Research Achievements |
By responding extremely quickly to environmental pressures, microbial assemblages can play an essential role as bioindicators of coastal health.
However, short-term microbial responses to typhoons are poorly characterized. In this project, DNA based methods in combination with physicochemical observations will be used to understand better the seasonal variability of prokaryote communities and transcriptional response to Red Soil Pollution (RSP), contributed to the coral reefs degradation, in nearshore areas affected by different land uses. The results obtained in this project will provide insights into prokaryote responses to RSP as well as the applicability of DNA based methods in coral reef ecosystem monitoring in Okinawa.
|
| Academic Significance and Societal Importance of the Research Achievements |
We believe that these results demonstrate that urbanization is strongly impacting physicochemical and nutrient conditions in Okinawa’s nearshore ecosystems.
This study highlights the importance of vegetation to limit run-off to coastal systems, as well as wastewater management.
