A three-month follow-up research fellowship sponsored by the Japanese Association of Student Services Organization (JASSO) was granted to SEAFDEC/AQD scientist Dr. Helen Marcial.

From 20 August to 20 October, Dr. Marcial conducted some parts of her study on the effects of climate change on zooplanktons, including rotifers (Brachionus rotundiformis, Brachionus plicatilis and Proales similis), cladoceran (Diaphanosoma celebensis) as well as phytoplankton (Nannochloropsis oculata). She investigated the effects of elevated temperature and ocean acidification on the reproduction, nutritional contents and size of zooplanktons, and cell proliferation of phytoplankton using a carbon dioxide chamber at the Institute for East China Sea Research Center in Mei, Nagasaki. She likewise visited several laboratories including the Chlorella Company in Fukuoka where she was able to observe recent developments in microalgal mass culture and preservation.

JASSO is an independent administrative institution that provides opportunity for researchers who have previously come to study in Japan. Dr. Marcial finished her doctorate degree in Nagasaki University in 2005. The research fellowship is intended to assist in the advancement of academic / scientific research in developing countries.
