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.

Notholca japonica

Notholca japonica

No.34 Type of Rotifer

Notholca japonica is a species of tiny aquatic invertebrate called a rotifer. Rotifers are important sources of food for fish, copepods, comb jellies, and jellyfish. Many are microscopic, feature bilateral symmetry, and have two wheels of cilia called a “corona” that help them to locomote or gather food. Notholca japonica is a marine species, and has been found in the Sea of Japan and the Sea of Okhotsk. This species is approximately 185-205 micrometers long and is translucent with red and orange internal organs. Species in the genus Notholca are known for their presence in Holocene-era sediments in Antarctica.

Fibrocapsa japonica

Fibrocapsa japonica

No.13 Type of Eukaryotic Algae

Fibrocapsa japonica is a type of eukaryotic algae called a raphidophyte. It is unicellular, golden-brown, has no cell wall, and possesses flagella. First reported in Japan, Fibrocapsa japonica blooms are potentially toxic to marine life and have been associated with large fish mortality events in Japan. It blooms worldwide in coastal temperate and tropical waters with high nutrient conditions. While the mechanism for its toxicity is not well understood, it is known to produce neurotoxins, mucocysts that can clog fish gills, haemolytic compounds that destroy red blood cells, and reactive oxygen species that injure gill tissue and cause asphyxia.

Lychaete japonica

Lychaete japonica

No.37 Type of Green Algae

Lychaete japonica is a species of marine green algae of the order Cladophorales. Whitish-green when alive, it grows in strong, upright, branched fronds that look dense and tufted. Most plants of this species grow up to 20 cm tall and are dark green when dead and dried. Found in the ocean south of the Tsugaru Strait in Japan, it grows on rocks near the low tide zone or in shallow water depths. Other Cladophorales species from the mid-Ordovician have possibly been found in the Winneshiek Shale in Iowa, USA.

Lotus japonicus

Lotus japonicus

No.02 Japanese Trefoil

Lotus japonicus is a perennial legume belonging to the Fabaceae family, the third-largest flowering plant family that includes economically important crops like soybeans, chickpeas, and alfalfa. The plant is bushy, grows branches approximately 30 cm long, generates yellow flowers, and self-pollinates. Lotus japonicus typically has a lifespan of 2-3 months, is diploid, and can be transformed by Agrobacterium, making it a “model” legume species for genomic studies. It has also been used in nitrogen fixation, nodulation, and plant physiology studies. The plant is distributed across East Asia and but has also been found in India, Pakistan, and Afghanistan.
