Ajime Dojo (Niwaella delicata)

Post by odyssey » Sun Nov 14, 2010 12:19 am

Hi everyone!

I keep Niwaella delicata(Ajime Dojo) inhabiting Japan. I keep Niwaella multifasciata inhabiting Korea together.
I believed that both were relation causes of the same genus, but, in fact, knew what there was not in relation.

I knew that N. multifasciata was moved from the Niwaella genus to the Kichulchoia genus recently.
N.brevifasciata was moved in the same way to the Kichulchoia genus, too.
http://d.hatena.ne.jp/OIKAWAMARU/20101006/1286338941

These were morphologically similar, but it seems to have been recognized that it was not relation as a result of DNA analysis.
Two kinds to inhabit are mentioned in China as the Niwaella genus elsewhere, but will be really so?

The creature classification by the form observation of the appearance is revised in sequence by DNA analysis.

In Japanese Niwaella delicata, DNA analysis of various local population is performed.
N.delicata is divided into two groups roughly, but, according to the result, there seem to be few the differences.

However, the variation of the design of its body is very big.
I realized that the classification based on the design of the body was unreliable.

I visited 11 rivers where Niwaella delicata inhabited and took a photo of a lot of them underwater.
It is a variation of the designs of N.delicata every river as follows.
Video clips are uploaded to Youtube, too.

Outstanding work Odyssey! I don't suppose you have a copy of the Kim paper do you? Have been after it for a while.

Hi everyone!
Matt wrote: I don't suppose you have a copy of the Kim paper do you?.
The paper I read is Dr. Kitagawa's one about a DNA analysis from Cobitis of Japan and Korea.
He did a mtDNA analysis about 9 species of 3 genus of the Korean Cobitis kinds.
As a result, the relation was not accepted between N. multifasciata regarded as a close species of N.delicata.
It became clear that the species of all Korean Cobitis kinds including N. multifasciata has a high affinity between the third group of the Japanese Cobitis genus.
Sorry,I can not find the English paper of his study.
Then Niwaella delicata seems to have been introduced into ancient Japan first more than Cobitis as a result of a time guess by the mutation rate of mtDNA.

In the latest Cobitis study, a family tree of Cobitis of the Eurasian Continent whole area seems to be done by DNA analysis.

When the water temperature falls, Niwaella delicata dives in a riverbed with spring water and stays over winter.
Therefore it won't be possible to see them at a river until next year.

When my passion doesn't cool during winter, I'll do photography in the water of "Cobitis takatsuensis" in a natural habitat next year.

Beautiful odyssey! So many variations in their markings!

P.S. are you happy with your S90? I just ordered an S95.

No problem Odyssey. The one I want is: Kim, I.S. (2009) A review of the spined loaches, family Cobitidae (Cypriniformes) in Korea. Korean Journal of Ichthyology, 21 (Suppl.): 7-28.

And I don't mind it in Korean!

Stupidly I have drained my S90 into the river with a waterproofing case in a summer vacation.
Thus I purchased S95 last week, too.
P.S. Sorry,I made a mistake in the thread which should have done a reply and have done a reply to other article yesterday.
