Ocean is the source of life and has given rise to biodiversity. To understand our planet and human beings, knowledge about marine organisms are essential. The 21st century is the era of life and environmental sciences. Shimoda Marine Research Center (SMRC), the center for the research and education of marine biology in University of Tsukuba, aims to explore the basic principles of life and interactions among organisms through education and research using both basic and advanced technologies on marine organisms.

imageProf. Jason Hall-Spencer and Assistant Prof. Ben Harvey at the Shimoda Marine Research Center, University of Tsukuba, revealed that ocean acidification could have broad reaching effects on ecosystems and the services they provide. Their new study provides a synthesis of the likely effects of ocean acidification on ecosystem properties, functions and services and is based on laboratory experiments and observations along natural gradients in CO2.
This result is now online at Emerging Topics in Life Sciences

The research team composed from Dr Agostini, Dr Harvey, Dr Wada, Dr Kon and Dr Inaba from the Shimoda Marine Research Center in collaboration with Dr Hall- Spencer from Plymouth University and Dr Milazzo from the University of Palermo, reported their finding from the studies at the Shikine Island CO2 seep in a paper published in Scientific Reports on July 27th 2018. They show that the increase in CO2 over the last century has already changed the structure of marine ecosystems and that if CO2 keeps increasing, this will lead to drastic simplification of the ecosystems and a loss in biodiversity.

Seeking a Postdoctoral Researcher in Marine Microbiology
We are now seeking a Postdoctoral Researcher in Marine Microbiology to work on vb the project [Investigating coral bleaching mechanisms and potential biochemical prevention/rescue measures] funded by the the Japanese Ministry of Environment “Environment Research and Technology Development Fund” (PI: Hiroyuki Fujimura, University of the Ryukyus). The selected researcher will work with the sub group [Omics and microscale studies of the resilience to bleaching]. His/her role will be to investigate the change in microbial communities (diversity, metagenome, etc.) under different treatments and investigate its role in resilience to bleaching. The researcher will work in close collaboration with Dr Sylvain Agostini and Dr Ikuko Yuyama (University of Tsukuba)
More details can be found here.
