Обь (65°15' с.ш. 65°29' в.д. – 66°38' с.ш. 66°20' в.д.), собраны на трех точках по направлению с севера на юг, для выявления светлых колец – годичные слоев прироста со светлой окраской, обусловленной нарушением процессов формирования поздней древесины, которые часто встречаются в экстремальных условиях произрастания. Получены видоспецифичные хронологии, которые использовали, чтобы изучить: 1) возможные причины, влияющие на образование светлых колец, и 2) реконструировать экстремальные климатические явления. Образование светлых колец в регионе нижней Оби в основном связано с необычно низкой средней температурой мая, июня и августа, но имеются различия между видами и по условиям местопроизрастания. Между 1880 и 2000 гг. было идентифицировано четыре года, когда формируются светлые кольца на всех местообитаниях у обоих видов, при этом у хронологий по лиственнице выявлено 11 общих лет, а у хронологий ели – пять. Множественный пошаговый линейный регрессионный анализ показал, что температуры мая и августа объясняют от 20 до 30% изменчивости количества светлых колец у ели, а мая или июня и августа 30–36% у лиственницы. Изучено влияние крупных извержений вулканов на формирование светлых колец в районе исследования.</p></abstract><trans-abstract xml:lang="en"><p>Cores of larch (Larix sibirica Ledeb.) and spruce (Picea obovata Ledeb.) were collected on three sites in Western Siberia along the Ob river (65°15' N 65°29' E – 66°38' N 66°20' E) to reveal light rings with purpose (1) to learn possible reasons to light ring formation along the Ob river and (2) to reconstruct extreme climatic events. In the study area the light-ring formation is connected with unusual low temperature of May, June, August, but conditions of light-ring formation are different between species and sites. The period 1880–2000 has 4 years with light rings in coniferous wood at all three sites. Larch light-ring chronologies have 11 common years and spruce chronologies have 5 years. Results of a multiple linear stepwise regression showed that May and June temperatures explain 20–30% of light ring variance in spruce, and May, June and August temperatures explain 30–36% of light ring variance in larch. Infl uence of big volcanic eruption to light-ring formation in the study area was investigated.</p></trans-abstract><funding-group xml:lang="ru"><funding-statement>Уральское отделение РАН</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Агафонов Л.И., Гурская М.А.
