IBO Challenge 2020 Results

IBO2020 in Nagasaki is cancelled due to the COVID-19 global pandemic. 
Instead, we are hosting a remotely-conducted competition (IBO Challenge 2020) in August-October, 2020. 

 

Message from the IBO2020 Organizing Committee 

I am very proud to announce that we are holding the IBO2020 competition in Sasebo, Nagasaki. Nagasaki is a historical and memorable place, as it is the last place that experienced an atomic bomb attack. Nagasaki is surrounded by a beautiful sea with hundreds of islands, where you can enjoy numerous marine organisms. Immersed in nature, we are sure that all the delegates will spend a wonderful time with friends from all over the world. We warmly welcome you all with some new challenges including an international group work activity. In addition, of course, you will enjoy our scientific tasks. 

Looking forward to seeing you all in July 2020.

Mauremys japonica

Mauremys japonica

No.06 Japanese Pond Turtle

Mauremys japonica is a species of freshwater turtle native to Japan. Females of this species can grow shells up to 21 cm long, while males grow smaller shells up to 14 cm long. Found across Japan except for the northern island of Hokkaido, Japanese pond turtles live in rivers, marshes, ponds, and irrigated rice fields. Its diet can include small amphibians, insects, algae, and earthworms. Although not currently considered threatened, habitat destruction via land development, exploitation from the pet trade, and the introduction of invasive turtle species have caused concern for native populations of Mauremys japonica.

Cryptomeria japonica

Cryptomeria japonica

No.17 Japanese Cedar

Cryptomeria japonica is a well-known and heavily planted species of evergreen conifer in Japan. They grow up to 50 meters tall, have peeling, reddish-brown bark, and aromatic blue-green needles. It is widespread in mountain forests in Japan and is cultivated in China. Rot-resistant and workable, its wood has historically been used to make buildings, bridges, ships, and furniture. The Japanese island of Yakushima is famous for its ancient Cryptomeria japonica trees, including one that is estimated at between 2,000-7,000 years old. Japanese cedars are infamous for producing pollen that is a major cause of hay fever in Japan.

Omphalotus japonicus

Omphalotus japonicus

No.14 Tsukiyotake

Omphalotus japonicus is a species of mushroom known in Japan as “tsukiyotake” or “moon night mushroom.” Like others in its genus, Omphalotus japonicus has a bioluminescent body in darkness. In daylight, it is often brown or orange, with caps that grow in a kidney or half-circle shape. It can be found in beech trees in cool, temperate forests in Japan, China, eastern Russia, and Korea. Omphalotus japonicus is poisonous if ingested, causing nausea and vomiting. It is often mistaken for other mushroom species that are edible, such as Shiitake and Hiratake mushrooms.

Leucothea japonica

Leucothea japonica

No.32 Type of Comb Jelly

Leucothea japonica is a gelatinous marine animal called a ctenophore or “comb jelly.” Its body is up to 20 cm long, oval-shaped, translucent, and incredibly fragile. Like other comb jellies, it has 8 plates of cilia (or “combs”) that run along its body that it uses to push itself through the water. The bright lights seen along its comb edges are produced by the diffraction of light off of its moving cilia. Leucothea japonica are found in the open oceans near Japan where they are known to squirt ink when disturbed, a rare trait among ctenophores.
