На основе выборки из 130 геоботанических описаний, сделанных авторами в 1995-2019 гг. или взятых из литературы, проведена доминантно-детерминантная классификация топких мезотрофных (Picea abies s.l.) ельников сфагновых, развивающихся при подтоплении либо периодическом затоплении в Европейской России и на Урале. Ценотическое разнообразие этих сообществ определяется спецификой названных процессов в сочетании с климатическими факторами, тогда как роль почвообразующих пород почти не выражена. Выделено 6 ассоциаций с 6 субассоциациями и 2 вариантами, всего 11 синтаксонов (табл. 1). В их числе подтопленные ельники вейниковые сфагновые с господством Calamagrostis purpurea s.l. и Equisetum sylvaticum в травяном ярусе (4 субассоциации в разных подзонах тайги либо долготных секторах), вздутоосоковые с Carex rostrata и C. vesicaria и вахтовые с Menyanthes trifoliata (2 субассоциации). Кроме того, выделены эндемичные для Южного Урала ельники малоцветковоосоковые с C. pauciflora и Rubus chamaemorus, развивающиеся на поверхностном дождевом стоке (2 варианта), приречные северотаежные водноосоковые с Carex aquatilis и затопленные южно- и подтаежные белокрыльниковые с Calla palustris. Для большинства синтаксонов характерны Swampy mesotrophic peatmoss spruce forests, dominated by Picea abies s.l. and originated due to inundation or periodical flooding, have been classified in European Russia and the Urals using the dominant-determinant approach to vegetation. The data set involves 130 relevés made by the authors in 1996-2019 or taken from the published sources. 11 syntaxa are totally recognized (see Table 1). Inundated reedgrass-peatmoss (with the dominance of Calamagrostis purpurea s.l. and Equisetum sylvaticum in the field layer; 4 subassociations in different subzones or longitudinal sectors), sedge-peatmoss (with Carex rostrata and C. vesicaria), and trefoil-peatmoss (with Menyanthes trifoliata; 2 subassociations) spruce forests are recognized. In addition, one can distinguish sedge-cloudberry-peatmoss spruce forests with Carex pauciflora и Rubus chamaemorus in the subalpine belt of the Southern Urals, developing due to surficial rain flow, also riverine northern-boreal sedge-peatmoss forests with Carex aquatilis and flooded southern- and hemiboreal calla-peatmoss spruce forests with Calla palustris. The observed syntaxonomic diversity is governed by inundation/flooding intensity and longevity together with latitudinal zonation and climate continentality, whereas the role of bedrock type influence is minimal. Multi-dominance and mutual replaceability are typical for peatmosses in most of the syntaxa.

An account is given of finding larvae of Aristotelia baltica A. Šulcs & I. Šulcs, 1983 (Gelechiidae) in a limestone area of Croatia, a different habitat from that previously known. This is apparently the first record from Croatia of a species that otherwise occurs from the Baltic States and European Russia eastwards to the southern Urals, apart from two moths reared in 1965 from Bosnia-Herzegovina.

On a basis of analysis of original and published data collected from north-eastern regions of European Russia, two new associations of tall herb boreal forest communities have been characterized. The first one, named Aconito septentrionalis—Piceetum obovatae Zaugolnova et Morozova ex Zaugolnova et al. hoc loco, was proposed earlier (Zaugolnova, Morozova, 2004). Now it has been validly described. Association is distributed in northern and middle boreal subzones. The second one, named Pulmonaria obscurae—Piceetum abietis ass. nova hoc loco, is specified and validly described for the fist time. It is distributed in southern boreal subzone. These two associations can be considered as a quasi-climax succession stage of spruce forests on their eastern border in the Russian Plain. These communities have the highest species diversity among taiga forests Together with three others forest associations, earlier described from the Southern Urals (Martynenko et al., 2008), the mentioned two belong to a new sub-alliance Atrageno sibiricae—Piceenion obovatae suball. nov. hoc loco within alliance Piceion excelsae Pawłowsky in Pawłowski et al. 1928 (in boreal-forest class Vaccinio-Piceetea). Block of the sub-alliance diagnostic species includes a functional group of boreal tall herb species. Their ecological and geographic characteristics have been described.

History Of

Приведена краткая история систематического изучения елей Урала и прилегающих территорий. Согласно мнению многих отечественных исследователей на Урале и в Предуралье ель сибирская испытывает значительное генетическое влияние ели европейской, что связано с историей образования и распространения гибридной ели в послеледниковое время и до настоящего времени. Отмечается существование на Южном Урале и в Башкирском Предуралье нескольких генетически различающихся популяций, приуроченных к определенным высотным поясам. Отмечены важные диагностические признаки репродуктивных органов P. obovata и гибридогенного вида P. fennica: форма и размеры (длина/толщина) зрелых шишек; угол отклонения семенных чешуй от оси раскрытой шишки; форма и цельность верхнего края семенной чешуи; размеры (длина и ширина), форма и окраска кроющих чешуй. В ходе морфолого-систематических и фитоценотических исследований ельников и анализа полученных результатов на территории национального парка «Таганай» впервые выявлены две морфологические группы ели сибирской (P. obovata). Эти морфологические группы приурочены к разным высотным поясам и разным растительным сообществам. Причем, между верхним и нижним высотными поясами существует переходная зона, где в составе лесных сообществ встречаются экземпляры обеих морфологических групп. Помимо ели сибирской (P. obovata), на исследуемых площадях выявлена ель финская (P. fennica (Regel) Kom., которая близка морфологически к P. obovata. Выявлены особенности распространения этих групп елей в пределах разных высотных поясов. The article presents a brief history of the systematic study of the spruce of the Urals and adjacent territories. According to many domestic researchers in the Urals and behind the Urals, of Siberian spruce has considerable genetic influence of Norway spruce, which is associated with the history of the formation and propagation of hybrid spruce in post-glacial time to the present. Some authors speak about the existence in the southern Urals in the Bashkir CIS-Urals of several genetically distinct populations, confined to particular altitudinal zones. Among the important diagnostic features of the reproductive organs hybridogenous P. obovata and P. fennica species marked with the following: shape and dimensions (length/thickness) of Mature cones, the angle of deflection of the seed scales from the axis of the open cones; form and integrity of the upper edge of the seed scale, the dimensions (length and width), the shape and color of covering scales. In the course of morphological-systematic and phytocenotic studies of spruce forests and analysis of the results obtained in the national Park Taganay was first revealed two morphological groups of Siberian spruce (P. obovata). These morphological groups dedicated to different high-altitude zone and different plant communities. Moreover, between the upper and lower altitudinal zones there is a transition zone, where the composition of the forest communities there are instances of both morphological groups. In addition to the Siberian spruce (P. obovata), in the study areas revealed the Finnish spruce (P. fennica (Regel) Kom.), which is close morphologically to P. obovata. Peculiarities of distribution of these groups of fir-trees within different altitudinal belts.

Within the Western slope of the Southern Urals, there are plenty of basite dyke complexes of Riphean to Vendian among Precambrian terrigenous-carbonate formations. In metamorphic formations of the Taratash complex (Archean to Early Proterozoic, the northern closure of the Bashkirian meganticlinorium) there was observed the andesitic dyke with isotopic age of 71±1 Ma (U-Pb SHRIMP II on zircons) and near Bakal two bodies of gabbroids with zircons of similar ages were found. These are the first evidence of possible Mezozoic magmatism in this region.
