Prof. Dr. Kozo Watanabe, accompanied by Ph.D. candidate KyleYoung Low, visited Universiti Malaya in Kuala Lumpur Malaysia. Their main objectives were to survey potential sampling sites, discuss future project designs, and lay the foundation for an International collaborative research lab (ICRL) in Malaysia. The 2-day visit proved to be productive.
The first day, June 5th, consisted of a field survey exploring the estuary of Kuala Selangor by boat.
After visiting an exposed seabed off the coast of the Selangor Estuary. The entourage continued the expedition car to a nearby coastal town to savour some local seafood delicacies before heading to the Selangor River Dam. Insights were gained through direct observations of the sites.
The next day, June 6th, a series of discussions and a lab visit were underway at Universiti Malaya.
The meetings centred around the progress of the LAMER project by Dr. ChoonWeng Lee and Dr. ChuiWei Bong. They have discussed future research collaboration, avenues of establishing an International collaborative research lab (ICRL) under Ehime University at Universiti Malaya, and cross-employment opportunities for academicians. The two universities plan to combine their research goals to shine a light on global occurrences of antimicrobial resistance (AMR), antibiotic pollution, metaviromics, and environmental pathogens on sites covered from the day before. Finally, a potential visit by our collaborators from Universiti Malaya is in the works.
No stone is left unturned.
Between meetings, the participants made a delightful visit to the botanical garden at Universiti Malaya for a guided tour with the local plant expert employed by the university. Edible parts were plucked and sampled from the medicinal plants first-hand, of course, with expert guidance!
With all things said and done. The visit was a productive one that concluded on a high note. With each interaction, the researchers witnessed the power of collaboration and the potential it holds for advancing scientific knowledge. Despite being an ocean apart, the shared vision and dedication of the teams transcend distance, together anything is possible.

Here, they talked about their lab experience and learnings:
Mia: Thank you MECOH Lab, I learned a lot about the environment from the scientist's point of view, supported by complete lab equipment. This will be useful for me in the future, especially for the sanitation sector which I have been studying on so far. Thanks to sensei and the students for all the knowledge. In addition, many foreign students in MECOH Lab has made my cultural preferences wider.
Naomi: I always feel very grateful for having experience in MECOH Lab because finally I could learn many things about microbiology, DNA, and PCR. It’s so wonderful for meeting many people from different nations and could learn about trivial things about anything in this world, exchanging culture and experience will be always a thing I want to try by myself. I also want to thank to Kozo Sensei for giving me chance to join the lab and all the students that help me to learn. Hope MECOH Lab will be this joyful as the time goes by!
Sidah: MECOH Lab will always be one of my great experiences. I learned many things in the laboratory, like being more disciplined, careful, and patient. I'm so happy to learn about DNA and molecular since it's a new topic for me. I want to thank Kozo Sensei, who allowed me to join his team, and Dan, who guided me patiently and explained the research in the Lab. People in MECOH Lab have warm hearts. I love the way they interact and support each other. Everyone is so gentle, supportive and passionate about doing the research.
Vita: Firstly I came to Japan, I felt afraid because I felt constrained language when communicating in the Japanese language and also English. But, I can handle that because of support from Kozo Sensei and the others member in MECOH Lab, especially Ken and Ngure, who was very patient and explained well until I understood the research. This is my new experience studying DNA, and I am interested in this research. Thank you to the Japanese in MECOH laboratory, especially Shimada and Naoya, who accompany and provide insight into Matsuyama and Japan.
Dr. Shinji Takahashi from Tohoku University, together with the Molecular Ecology and Health Laboratory members Mr. Arthien Pelingen (Researcher), Mr. Karim Clivaz (M2), and Mr. Tsubasa Moriya (B4), collected environmental DNA (eDNA) and macroinvertebrates from Tenryu River, Shizuoka Prefecture on November 9-11, 2022.
This recently concluded field work also serves as a follow-up of the August collection trip this year (Read here: collaborative-fieldwork-of-three-universities-in-kizu-and-tenryu-rivers.html). Accordingly, we focused on (1) identifying Ayu (Plecoglossus altivelis altivelis) spawning sites and on (2) observing macroinvertebrate distribution in relation to the riverine spatial habitat diversity.
On this three-day activity, we have successfully confirmed spawning of Ayu this season and positively identified different habitat types as we recorded various environmental parameters such as water temperature, pH, turbidity, etc. to be correlated in several macroinvertebrate studies.

At the start of August 2022, Art from the Philippines joined the MEcoH Lab as the newest PhD student. Emerging from a rigorous taxonomic training of Philippine macroinvertebrates during his Master’s in the Ateneo de Manila University (AdMU), Art will explore combined ecological and genomic approaches in studying the stream macroinvertebrates i.e. how the abiotic factors and genetic similarities and/or differences play into their roles in the river dynamics. With these in sight, he envisions to contribute into an interdisciplinary understanding of addressing the changes in current environmental patterns using macroinvertebrates as models.
Dr. Levente-Péter Kolcsár (JSPS postdoctoral fellow) went on a field collection trip to Hokkaido between 18-29 July.
Dr. Daichi Kato from Echigo-Matsunoyama Museum of Natural Science, Matsunoyama, Niigata Pref. also joined the field collection between 19-22 July.
Aims and preliminary results of the trip:
1. Collecting additional specimens from two species new to science, which first time collected during another field trip in Hokkaido, in 2019. Both new species are only known to be found in 2 locations in 2019. During a recent field trip the new species were also found in additional 5 localities.
2. Collecting rare or poorly known crane fly species for future taxonomic studies.
3. A general survey of Hokkaido’s crane fly fauna. Due to the special geographic position of Hokkaido Island we suspect the presence of several species which are known from continental Asia, North-America and Kuril Island, but not yet reported from Hokkaido.
In total dr. Kolcsár and dr. Kato collected around 1500 specimens from 30 collection sites.
Some poorly known species collected during the field trip.
