Treeline Ecotone

During the last 100 years, rapid advances of trees towards higher elevations and latitudes have been recorded for various regions worldwide, including the Ural Mountains. Climate warming and tree cover increases can lead to significant changes in the high-mountain vegetation. Direct observations on the vegetation of high-mountain regions provide evidence for an increase in the species diversity of plants at high elevations and changes in the composition of the alpine communities. This study investigated the diversity and distribution of vascular plants within the present-day treeline ecotone in Mount Iremel, the Southern Urals. The dataset (Trubina and Nesterkov 2021, available from the GBIF network at https://www.gbif.org/dataset/284f1484-10b7-4ef5-87b7-9de1159e6b42) presents the results of an assessment of species richness and frequency of vascular plants at the different elevation levels (from 1203 to 1348 m a.s.l.) and different biotopes (birch-spruce shrub forest, birch-spruce sparse forest and spruce forest with fragments of meadow plant communities) within the treeline ecotone in Mount Iremel, Southern Urals. Observations were carried out at 700 sampling plots with two estimation methods: small-size plot (0.5 × 0.5 m) sampling (672 plots in total) and large-size plot (10 × 10 m) sampling (28 plots). The dataset includes 700 sampling events (= sampling plots), corresponding to 5585 occurrences (vascular plants, mainly identified to species) observed during July 2003. Only occurrences containing plant taxa (occurrenceStatus = present) have been provided. The dataset includes information about distribution and frequency of the Ural endemic species (Anemone narcissiflora subsp. biarmiensis (Juz.) Jalas, Calamagrostis uralensis Litv., Cerastium krylovii Schischk. & Gorczak., Festuca igoschiniae Tzvel., Hieracium iremelense (Elfstr.) Üksip, Lagotis uralensis Schischk, Pleurospermum uralense Hoffm.) and the Pleistocene relict species (Alopecurus magellanicus Lam., Bistorta vivipara (L.) Delarbre, Cerastium pauciflorum Stev. ex. Ser., Pedicularis oederi Vahl, Saussurea controversa DC., Swertia perennis L.). The dataset also provides information that can be useful for estimating biodiversity and plant communities composition within the treeline ecotone at a specified time period and contributes to the study of biodiversity conservation in the Ural Region.

The Tatra Mountains

The Carpathians, particularly their highest massif, the Tatra Mountains, exhibit the greatest richness of endemics in Poland. The present paper is a critical recapitulation of existing knowledge of endemism among the vascular plants of the Polish part of the Carpathians. It comprises a list of all 110 taxa (49 species, 26 microspecies of the genus <em>Alchemilla </em>and 35 conspicuous subspecies) that can be considered Carpathian endemics or subendemics. Their distribution, vertical ranges and habitats are characterized.

The paper presents the transformations of species composition in the main plant communities of the Karkonosze Mts. subalpine and alpine belts during the last 35 years. The investigations of floristic changes were performed in associations: <em>Carici (rigidae)-Nardetum</em>, <em>Carici-Festucetum supinae</em>, <em>Crepidi-Calamagrostietum villose</em> and <em>Empetro-Vaccinietum</em>. Signalized are also some vegetation transformations in the remaining belts. The progressing floristic degradation of plant communities in the subalpine and alpine belts consists in: (a) expansion of grasses, (b) decline of rare vascular plants, and (c) elimination of terricolous bryophytes and lichens. In spruce forest belts declining are species connected with old-growth spruce forests like: <em>Listera cordata</em> and <em>Moneses uniflora</em>. The changes of plant communities of low mountain swards (<em>Nardetalia</em>) caused by cessation of pasture and mowing in the cause of retreat of many rare plants, like e.g., <em>Arnica montana</em>. The main cause of the still lasting in the Karkonosze Mts. community transformations is the changes in soil environment connected with anthropogenic nitrogen fertilization. The large inflow of mineral nitrogen from the atmosphere (1138 mg/m<sup>2</sup> sum for vegetation season) is the reason of accelerated rate of decomposition of organic matter and intensified nitrification. The high content of nitrates in soil (5 times higher than in the Tatra Mts. swards) is the reason of expansion of graminoids, mainly <em>Deschampsia flexuosa</em>, <em>Calamagrostis villosa</em> and <em>Carex bigelowii</em> subsp. <em>rigida</em>. The overfertilisation of habitats causes the retreat of rare high mountain vascular plants and the decline of terricolous bryophytes and lichens.

Multicellular green algae may be an ancestral form of the vascular plants. These algae exhibit cell wall structure, chlorophyll pigmentation, and physiological processes similar to those of higher plants. The presence of a vascular system which provides water, minerals, and nutrients to remote tissues in higher plants was believed unnecessary for the algae. Among the green algae, the Chaetophorales are complex highly branched forms that might require some means of nutrient transport. The Chaetophorales do possess apical meristematic groups of cells that have growth orientations suggestive of stem and root positions. Branches of Chaetophora incressata were examined by the scanning electron microscope (SEM) for ultrastructural evidence of pro-vascular transport.
