Lab retreat to Iheya

Posted on by


Our lab decided to take a trip to Iheya island the second week of December 2017, in order to explore different parts of Okinawa, but also to celebrate the end of Cong’s PhD defense and Yuka’s proposal defense.

The island is full of goats and sculptures made from marine debris. We also visited a cave, a beach, hiked to the top of a small mountain, and had some good food and drinks.


Nick (our post-doc who does a lot of research on acoustics and birds) also did some bird watching on the island, and below is a list of birds he saw on Iheya:

Eurasian Teal
Suzume
Hiyodori
Chinese Turtle Dove
Japanese Bush Warbler
Pale Thrush
Blue Rock Thrush
Japanese White-eye
Grey faced Buzzard
Japanese Sparrowhawk
Japanese Wood Pigeon
Little Grebe
Great grey egret
Osprey
Little egret
Pacific Swallow
Intermediate Egret
Zitting Cisticola
Daurian Redstart
Tufted Duck

Apart from bird watching, Takuma (our technician leading the field team who is a great taxonomist) also collected insects during our hike.

Until next time, Iheya!

Listening to ecosystems: New study published using acoustic monitoring to study Okinawa’s “Soundscape”

Posted on by

At every OKEON site there is a small green box attached to a tree. These boxes are acoustic monitors, and they are recording natural sounds almost constantly. As part of the OKEON project, we use these natural sound recordings, or “soundscapes”, as a way of monitoring biodiversity.

Sam Ross sets up an acoustic monitoring device at the OIST field site.

We collect more than 1 terabyte of audio data every week. If you wanted to listen to all of the recordings we’ve made so far, it would take you about 8 years… if you listened all day and never went to sleep. To sort through all this audio data, we use two approaches. First, we break the sounds up into sounds at different frequencies (i.e., pitch). This lets us get a big picture view of when and where animals are active on Okinawa. Second, we use machine learning to train our computers to detect species in which we are interested. This helps us understand more about which particular species are in each area of the island, and how their behavior varies across the year.

In many parts of Okinawa, humans and nature live close together. Managing this interaction is important for preserving wild populations of plants and animals.

Ultimately, our project aims to understand the ways that human activity affects Okinawa’s wildlife, and how we can better protect these species in the future. For more information (including videos), please see the OIST press release. A link to the study can be found here.

On Saturday, July 29th, many collaborators of the OKEON Churamori Project along with the general public gathered at OIST to attend the OKEON Churamori Project Symposium 2017. This event was the project’s first symposium and it was a great success, with over 170 attendees, interesting and informative talks, a panel discussion, and a post-symposium gathering that included hands-on exhibitions and a poster session where participants were able to exchange ideas.

OIST Science Challenge 2017: Measuring Biodiversity

Posted on by

OIST Science Challenge 2017 was put together by the Graduate School over five days (3/6-3/10) to allow Japanese undergraduate students to explore their careers as scientists and researchers. The students were involved in hands-on activities set up by different labs in order to learn about the research conducted at OIST as well as learn experimental and research methods.

Arilab hosted a an activity based around measuring biodiversity. Our “measuring biodiversity” activity is the most popular one this year, with 12 students signing up. The goal of the activity is for students to apply concepts of biodiversity to a tangible challenge: designing a one-hour project to quantify the diversity of insects in a petri dish. After this activity, students should critique their success and use this experience to design future project ideas. The material used in this activity is provided by the OKEON Churamori Project.
