Ruderal vegetation of Kyiv City. I. Class Stellarietea mediae Tx. et al. in Tx. 1950

This article, which is the first contribution in a series on the ruderal vegetation of the city of Kyiv, presents results of our studies of Stellarietea mediae plant communities occurring in the city. Their current state and phytocoenotic diversity has been determined. Based on modern methods of statistical data analyses, a classification scheme of Stellarietea mediae vegetation in the study area was developed and the leading factors of territorial and ecological differentiation of phytocoenoses were identified. It has been established that within Kyiv City, this class is represented by 24 associations and 3 basal communities belonging to 8 alliances and 4 orders. Their territorial distribution determines the types and intensity of anthropogenic disturbances, as well as the types of soil and its mechanical structure. Selected syntaxa are characterized and compared with their equivalents from other areas of Ukraine. It has been found that the main differences are at the level of co-occurring species, the composition of which mostly correlates with the types of anthropogenic disturbances and availability of water and mineral nutrients. According to the results of the ordination, it has been found that the distribution patterns of plant communities of Stellarietea mediae occur along the salt regime gradient of the edaphotope, as well as of ombro-, cryo-, and thermal regimes of the climate. Based on the phytoindication analysis, the ecological optimums of the plant communities in relation to the leading ecological factors were determined. The performed research supplements the available information about the presence and distribution of such associations as: Digitarietum ischaemii, Setario viridis-Erigeronetum canadensis, and Ambrosietum artemisiifoliae, in the territory of Ukraine. The proposed syntaxonomic scheme should become a basis of typological developments for strategic planning and practical implementation of activities for optimizing the urban environment and for sustainable development of the Kyiv urban agglomeration.

Investigation of vegetation as a precondition for improving the management of a national nature park (on the example of Dzharylhatskyi NP)

The protected area of Dzharylhatskyi National Park is only 3% of the total area. This is not enough to preserve dynamic ecosystems that are very vulnerable to natural factors and almost impossible to restore following damage by anthropogenic factors. In the investigated area there are territories with high potential for conservation, which are characterized by the presence of species from the Red Data Book of Ukraine and International Red Lists, plant communities from the Green Data Book of Ukraine and biotopes of global significance. The proposed ten sites should receive protected status, which will bring the protected area up to the necessary minimum to preserve the rare ecosystems of the park from tourism and economic pressure, which have intensified in recent years. For the period of research in 2014–2018, 14 types of sozophytes were identified and confirmed, two of them are the highly localised species endemic to Dzharylhach Island: Molinia euxina Pobed. and Poacynum russanovii (Pobed.) Mavrodiev, A. Laktionov et Y. Alexeev. The syntaxonomic structure of the sozologically valuable coenoses is represented by two basal communities, two subassociations and 8 associations belonging to 9 alliances, 9 orders and 9 classes. Out of them, we provisionally propose the new following groups: ass. Apero maritimi-Chrysopogonetum grylli nom. prov., subass. Apero maritimi-Chrysopogonetum grylli, Stipetum borysthenicae nom. prov., subass. Cladietum marisci, Caricetum extensae nom. prov., BC Molinia euxina [Molinion caeruleae] nom. prov. The proposed sites represent 8 biotopes from Annex I of the Habitat Directive, which imposes obligations for their conservation at the world level. We carried out an analysis of the Ukrainian legislative acts, their correlation with international requirements and the zoning of the NPP “Dzharylhatskyi” in relation to these requirements and recommendations. Thus, the urgent need to expand the boundaries of the protected area of the Dzharylhatskyi National Nature Park by including distinguished protected tracts has been confirmed.

Plant communities of perennial succulents in the Caspian Lowland

Six plant communities of the class Salicornietea fruticosae Br.-Bl. et R. Tx. ex A. Bolòs y Vayreda 1950 registred in the northern part of the Caspian Lowland: basal communities Halocnemum strobilaceum–[Salicornietea fruticosae], Halocnemum strobilaceum–[Thero-Salicornietea–Salicornietea fruticosae] and Halocnemum strobilaceum–[Artemisio santonici–Puccinellion fominii], subass. Puccinellio fominii–Halimionetum verruciferae limonietosum suffruticosi Shelyag-Sosonko et al. 1989 and also two new associations — Suaedo confusae–Kalidietum caspici and Suaedo corniculatae–Halimionetum verruciferae are described in the paper.

El presente artículo es un estudio fitosociológico de la vegetación de la alta montaña del sur del Perú (departamentos de Arequipa, Moquegua, Puno y Tacna). En base a la relación existente entre geomorfología, litología, altitud, pisos bioclimáticos, intervalos de precipitación, descripción bioclimática, y la combinación florística en determinados biotopos, fueron diferenciadas las comunidades de 9 clases (Anthochloo-Dielsiochloetea, Calamagrostietea vicunarum, Lantano-Chusqueetea, Lemnetea minoris, Not holaenetea niveae, Phragmito- Magnocaricetea, Plantaginetea australis, Planta gini rigidae-Di.slichietea muscoidis y Potametea). Como resultado, fueron descritos 2 nuevos órdenes (Calamagrostietalia nitidulae y Salpichroetalia glandulosae), 7 alianzas (Azorello-Festucion, Belloo-Salpichroion, Cha etantherion sphaeroidalis, Cortaderion jubatae, Fabianimi stephanii, Hypsello-Plantaginion y Nototrich ion obcuneatae), 10 asociaciones (Belloo- Dissanthelietum, Chersodomo-Valerianetum, Cortaderietuin jubatae, Diplostephio-Parastrephietum, Dunalio-Baccharidetum, Nototricho-Xenophylletum, Parastrephio-Festucetum, Ranunculetum limoselloidis, Stuckenietum punensis y Wernerio-Puccinellietum) y 16 subasociaciones y comunidades fragmentarias (comunidades basales, BC y comunidades derivadas.
