The Impact

Picea abies L. Karst is undeniably one of the most important tree species growing in Slovakia. In addition to natural mountain spruce forests, monocultures planted in lower areas are also quite common. In this article, we analyze the climate–growth response differences between these two types of spruce stands in the context of local climate change consequences. The study area representing natural mountain spruce forests is located under Osobitá Mt. (Tatra Mountains, Slovakia), while the analyzed low-lying planted monoculture is situated near Biely kríž (Malé Karpaty Mountains, Slovakia). Temporal variation of the dendroclimatological relationships was expressed by the running Spearman correlation coefficient during the observed period 1961–2018. The results showed crucial differences in the dendroclimatological relationships between the selected study areas. For the natural mountain spruce stand, consistent, weak, and positive correlations to the temperature variables were typical, with negative relationships to precipitation during the growing season. In this case, the negative impact of a recent temperature rise was limited. In contrast, the monoculture reacted to the temperature variation during the growing season with fluctuations, while in the case of precipitation, almost no dependence was found. Such incoherency may be a consequence of worsened health conditions, as well as insufficient resiliency to climate-driven stress. The importance of this paper is in its wide applicability, mainly in forestry.

The flight activity of spruce tenthredinids were studied using Malaise traps and yellow sticky boards in young spruce forests in the Nízký Jeseník Hills during years 2005 and 2006. In most cases, studied species (<I>Pristiphora abietina, Pristiphora saxesenii, Pristiphora gerula, Pristiphora leucopodia</I>) showed a statistically significant correlation between numbers of specimens caught at two- or three-day periods and numbers of budded spruces in both years.

Over Time

Are the dynamics of natural subalpine spruce ( Picea abies (L.) Karst.) forests of central Europe governed by stand-replacing disturbances caused mostly by winds or by moderate disturbances resulting from bark beetle outbreaks? We analyzed tree-ring series from subalpine spruce forests in two mountain ranges of the Western Carpathians to determine the frequency and severity of disturbances and their effects on tree recruitment. The boundary-line method was employed to identify significant growth releases, interpreted as results of disturbances. In both study areas, major releases were not numerous but were regularly distributed over time. We found no evidence for stand-replacing disturbances. This result contrasts sharply with earlier findings from the Western Carpathians. The age structure of the forests studied indicates that the amount of tree recruitment was greater 150–200 years ago than in the subsequent 150 years. Our results suggest that stand dynamics in the forests analyzed are driven by numerous events of limited spatial extent and that stand-replacing disturbances are not necessary for the development of unimodal age structure.

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.

Mollusc Species

The recent research has shown a high malacological value of the Skalní Potok Nature Reserve that had never been searched for molluscs. The reserve hosts 49 mollusc species, which represents almost 20% of the entire Czech malacofauna. Such richness can be explained mainly by a high habitat diversity of the target area. Several types of forest such as ravine forests, alder carrs, herb-rich beech forests and spruce forests alternate on the area of 2 km². Among endangered species, the most interesting findings represent sensitive species from the family Clausiliidae, chiefly Bulgarica cana, Clausilia cruciata, and Ruthenica filograna. This area deserves the strictest protection as the reserve belongs to one of the well-preserved remnants of deciduous leaf forests in the Hrubý Jeseník Mts.
