Ecological features of the alien species Pistia stratiotes L. in different habitats of the secondary distribution range (Ukraine)

Online veröffentlicht: 09 Jul 2022
Seitenbereich: 361 - 370

Zusammenfassung

Abstract

We have analyzed structural and dynamic characteristics (production, morphometric parameters, phytocoenotic features and invasive behavior) of two locations with the alien species Pistia stratiotes L. in different types of water bodies, by origin, use and trophic status (a drainage canal and oxbow lake) in the outskirts of Kyiv. It is possible that in the case of increased anthropogenic eutrophication due to inorganic nitrogen, mother plants become smaller and more compact. The variability of morphological features increases. We also have distinguished growth of invasive potential of the species in the conditions of the water bodies of the region.

Muscari baeticum (Scilloideae, Asparagaceae), a new addition to the native flora of Tunisia and third report to Mediterranean Africa

Online veröffentlicht: 09 Jul 2022
Seitenbereich: 355 - 360

Zusammenfassung

Abstract

Muscari baeticum, originating from western Europe, is here recorded as new from the central eastern part of Tunisia. So far, it was known only from Algeria and Morocco within the southern part of the Mediterranean basin. Description of the species as well as first data about its ecology in Tunisia together with geographical distribution and diagnostic features of closely related species are given. Photographic illustrations of the new reported taxon and an updated key to the Muscari species in North Africa are also provided.

Phytosociological and ecological peculiarities of Festuca pallens Host in Ukraine

Online veröffentlicht: 09 Jul 2022
Seitenbereich: 235 - 252

Zusammenfassung

Abstract

This article deals with phytosociological and ecological requirements of the vulnerable species Festuca pallens in Ukraine. Based on the analysis of 51 relevés, we have recognized the occurrence of Festuca pallens in three associations within the Festuco-Brometea class. Some communities where Festuca pallens occurs have transitional stages of succession to forest edge vegetation according to the expert system classification. In addition, we evaluated the ecological differences among occupied habitats using Didukh’s phytoindication scales and concluded that the most important ecological factors are soil humidity, nitrogen content, soil aeration, salt regime, carbonate content, thermoregime, and climate continentality. Finally, we evaluated the threats to the existence of these communities with the presence of Festuca pallens, taking into account climate change and other impacts of anthropogenic activities (illegal mining, recreation, afforestation).

On the distribution and conservation status of some rare orchid taxa (Orchidaceae) in Bosnia and Herzegovina (Western Balkans)

Online veröffentlicht: 09 Jul 2022
Seitenbereich: 327 - 346

Zusammenfassung

Abstract

Albeit rich in a number of taxa, flora of Orchidaceae in Bosnia and Herzegovina has not been sufficiently studied. The paper presents distribution of ten rare and threatened orchid taxa in the territory of Bosnia and Herzegovina. Serapias bergonii and Himantoglossum calcaratum subsp. rumelicum are new for Bosnia and Herzegovina, while for other studied taxa (Serapias parviflora, Serapias vomeracea, Himantoglossum adriaticum, H. calcaratum subsp. calcaratum, Gymnadenia frivaldii, Pseudorchis albida, Orchis quadripunctata, Cypripedium calceolus) in addition to field investigation, checking and revision of herbarium material, as well as literature sources were also used for supplementing distribution data. The distribution maps of these taxa in Bosnia and Herzegovina are created on a 10 km × 10 km MGRS grid system. Based on the IUCN Red List criteria, the threat status in Bosnia and Herzegovina was assessed for all studied taxa. Data concerning their habitat preferences and population size are also provided.

Phytosociological analysis of acidophytic alpine mat-grass swards in the Julian Alps and the Karawanks

Online veröffentlicht: 09 Jul 2022
Seitenbereich: 253 - 295

Zusammenfassung

Abstract

Acidophytic alpine mat-grass swards are rare in the alpine belt of the predominantly calcareous Southeastern Alps of Slovenia, mostly occurring where limestone is admixed with marlstone or chert. Those for which we were able to make phytosociological relevés can be classified mainly into two syntaxa: Carici curvulae-Nardetum strictae vaccinietosum gaultherioidis and Sieversio-Nardetum strictae vaccinietosum. At slightly lower elevations, in the forest zone of the subalpine plateau Pokljuka, we found similar swards occupying small areas in frost hollows with luvisol on limestone. They include character species of various subalpine-alpine sward and snow bed communities and are classified into the syntaxon Homogyno alpinae-Nardetum scorzoneroidetosum croceae.

Syntaxonomical survey of cork oak forests (Quercus suber L.) in the province of Tizi Ouzou, Kabylia, Northern Algeria

Online veröffentlicht: 09 Jul 2022
Seitenbereich: 297 - 325

Zusammenfassung

Abstract

This study is a contribution to the knowledge of the floristic composition and syntaxonomical significance of Quercus suber woodlands of Tizi Ouzou province, which represent the last remnants of ancient forests. The field surveys were taken in several locations representative of cork oak woodlands, using the Braun-Blanquet method. A matrix of 96 phytosociological relevés and 160 plant taxa was treated with clustering analysis and correspondence analysis. These multivariate analyses showed congruent results and allowed the definition of four main clusters of cork oak woodlands, corresponding to four syntaxa according to synecological and syndynamic gradients. They belong to three associations, of which one is newly described, and two subassociations. They are: Sileno imbricatae-Quercetum suberis ass. nov., a mesophilous association newly described here, on siliceous soils and in the humid ombrotype; Cytiso villosi-Quercetum suberis, a mesophilous association, with two subassociations: quercetosum canariensis, and myrtetosum communis, this later reported for the first time in the study area, and both localized in the humid ombrotype and confined on markedly acid soils; Erico arboreae-Myrtetum communis, thermophilous secondary shrubland association developed in the subhumid ombrotype, on flysch substrates, also identified for the first time in this area. Syntaxonomic, synecological and syndynamic considerations are given for each syntaxon.

First record of Ficus microcarpa L. f. (Moraceae) in Algeria

Online veröffentlicht: 09 Jul 2022
Seitenbereich: 347 - 354

Zusammenfassung

Abstract

The escape from cultivation of Ficus microcarpa (Moraceae, Magnoliopsida) in Algeria is here reported. Several localities where the species reproduces from seeds have been discovered recently in northeastern Algeria. A map of its current distribution in the study area is provided. The species colonizes mainly urban habitats (walls, balconies and sidewalks) but its propagation in the natural environment is being facilitated by birds that disseminate the seeds over long distances. Ficus microcarpa can be considered as in the process of naturalization in Algeria. An updated key to species of the genus Ficus in Algeria is provided.
