Stoneflies (Plecoptera) of Northeast Asia and adjacent regions
Bibliographic record
Abstract
The Northeast is a special region of the Asia, including the Chukotka, Yakutiya, Kamchatka and Magadanskaya Oblast, which along with Alaska (USA), Yukon and the Northwest Territories (Canada) were part of ancient Beringia in the past.Currently, a total of 156 stonefl y species from 49 genera and 9 families with 61 species in the Asia and 104 species in American part are known for Beringia.Among them there are eight common species, Capnia nearctica Banks, 1918, Eucapnopsis brevicauda (Claassen, 1924), Mesocapnia variabilis (Klapálek, 1920), Nemoura arctica Esben-Petersen 1910, Podmosta weberi (Ricker, 1952), Arcynopteryx dichroa (McLachlan, 1872), Diura bicaudata (Linnaeus, 1758) and Plumiperla diversa (Frison, 1935), and 22 common genera, demonstrating important role of Beringia in intercontinental faunistic exchanges and in independent development of present West Nearctic and East Palearctic stonefl y faunas.There are nine species, known to be endemic, namely: fi ve American, Mesocapnia bergi (Ricker, 1965), Podmosta weberi, Alaskaperla ovibovis (Ricker, 1965), Isoperla katmaiensis Szczytko et Stewart, 1979 and I. decolorata (Walker, 1852), and four Asian species, Capnia tshukotica Zhiltzova et Levanidova, 1978, C. levanidovae Kawai, 1969, C. kolymensis Zhiltzova, 1979 and C. kurnakovi Zhiltzova, 1978).The species richness distribution in the Northeast Asia stonefl y fauna corresponds to the general patterns and increases with the advancement from the Arctic deserts to the taiga zone and from the maritime monsoon climate to the continental one.The lowest species richness was noted in the tundra watercourses of the Chukotka, the greatest is in the streams and rivers of the taiga zone in the Magadanskaya Oblast.The richness of stonefl y species in Kamchatka, located to the south, is poorer than the Magadanskaya Oblast due to paleogeographycal events and volcanic activity of the Kamchatka-Koryak volcanogenic belt.The composition and similarity of regional faunas is briefl y considered.The species Paraleuctra cercia (Okamoto, 1922) and Plumiperla diversa (Frison, 1935) are reported for Chukotka for the fi rst time.Резюме.Северо-Восток -особый регион Азии, включающий Чукотку, Республику Саха (Якутию), Камчатку и Магаданскую область, которые вместе с Аляской США, Юконом и Северо-Западными территориями Канады в прошлом входили в состав древней Берингии.В настоящее время для Берингии известно 156 видов веснянок из 49 родов и 9 семейств, из них 61 вид в азиатской и 104 вида в американской части.Среди них восемь общих видов:

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
