Justification of invasiveness criteria for alien plant species in Ukraine

Abstract

Abduloyeva O.S., Karpenko N.I., 2012: Justification of invasiveness criteria for alien plant species in Ukraine. Chornomors’k. bot. z., Vol. 8: №2: 252-256.

 

Eleven characters that characterize potential invasiveness of species or their populations are suggested as the criteria to assess the risk of alien species phytoinvasion. This study is based both on the analysis of the invasive plants’ features in Ukraine and a number of literature sources.

Hornbeam forests on the southern edge of their distribution

Abstract

Mala Y.I., 2012: Hornbeam forests on the southern edge of their distribution. Chornomors’k. bot. z., Vol. 8: №3: 265-283.

 

Syntaxonomy of hornbeam forests on the boundary between forest-steppe and steppe zones of Right-Bank Ukraine is presented. The communities belong to the class Querco-Fagetea, to the order Fagetalia sylvaticae, to the union Carpinion betuli and 2 associations, four sub-associations and two variants that are new and described for the first time. A comparative and cluster analysis together with phytoindication are applied for justifying description of new syntaxa. The analysis of results shows a sufficient difference between the hornbeam forests on southern edge of its natural distribution and typical hornbeam forests of forest-steppe zone.

 Structure of leaf surface in section Medium DC. of genus Campanula L. in the flora of Ukraine

Abstract

Dremliuga N.G., Futorna O.A., 2012: Structure of leaf surface in section Medium DC. of genus Campanula L. in the flora of Ukraine. Chornomors’k. bot. z., Vol. 8: №3: 284-301.

 

The structure of the leaf epidermis surface of 22 species from section Medium DC.of genus Campanula L. in the flora of Ukraine is investigated for the first time using a scanning electron microscope. The common characters for all species (amphistomous type of leaf blade, evenly spaced, not immersed anisocyte stomata, a well-developed crinkled cuticle; awl- and sickle-shaped, bearded and hoary downiness, the location of wax deposits - crusts and / or laminas; a common type of topography) and specific characters (relief type,  peculiarities of hairness) are identified.

A comparative characteristics of flowering time of 15 cultivars and forms of Zizuphus jujuba grown in Kherson region are given. The numbers of the effective temperatures (> 10 º C) at the beginning and at the end of flowering time are presented.

Bryobionta of the Ukrainian Livoberezhya: a taxonomical analysis

Abstract

Boiko M.F., 2012: Bryobionta of the Ukrainian Livoberezhya: a taxonomical analysis. Chornomors’k. bot. z.,Vol. 8, № 3: 306-312.

 

A comparative species analysis for divisions and classes in bryofloras of phytogeographical regions of Ukrainian Livoberezhyarevealed for Levoberzhne Polissya - 272 species (incl. 3 from Anthocerotophyta, 46 - Marchanthoiphyta and 223 species from Bryophyta), for Levoberzhna Forest-steppe - 229 species (incl. 2 - Anthocerotophyta, 28 - Marchanthoiphyta, 199 - Bryophyta), from Levoberzhna Steppe - 290 (1 - Anthocerotophyta, 31 - Marchanthoiphyta, 258 - Bryophyta). Among 385 species of bryobionta in Ukrainian Levoberzhya, 165 species are common for all three phytogeographical areas, that includes less than a half of the bryoflora species (42.8%). Among them, 1 species from Anthocerotophyta, 17 - Marchanthoiphyta and 147 -Bryophyta. Among Bryophyta, Briopsida dominates - 125 species (upper-sporiferous mosses - 71 species, side-sporiferous mosses  - only 54), 13 species of  Sphagnopsida and 9 -  Polytrichopsida. There are 165 species of bryobionta in all three areas of Ukrainian Livoberezhya, 82 species are found in certain two areas; 138 of 385 species of bryobionta are specific for phytogeographical areas that comprizes 35.8% of the bryoflora of Ukrainian Livoberezhya. Among them, 81 species are found in Levoberezhna Steppe, 42 -  Levoberezhne Polissya, and only 15 species - in Levoberezhna Forest-steppe. The Bryoflora Specificity Coefficient (BSC) is offered. Among three Bryofloras studied, the highest meanings of the coefficient are in Levoberezhna Steppe - 21.03, Levoberezhne Polissya - 10.9, the lowest BSC is in Levoberezhna Forest-steppe - only 3.89.

Taxonomy importance evaluation of morphometric parameters for identification of green phytomonades from Moewusinia clade (Chlorophyta, Chlamydomonadaceae)

Abstract

Pavlovska M.M., Nenyuk M.S., Tarieiev A.S., Kostikov I.Yu., 2012: Taxonomy importance evaluation of morphometric parameters for identification of green phytomonades from Moewusinia clade (Chlorophyta, Chlamydomonadaceae). Chornomors’k. bot. z., Vol. 8: №3:313-320.

 

The main morphometric parameters are identified for the 12 species of Chlamydomonas, which belong to the molecular Moewusinia clade, with 15 strains (including 12 authentic) as an example. Those parameters are assessed for the first time on the ground of slant culture as the criteria of the specific and intraspecific level within investigated clade. It is revealed that according to the criteria of the width of the cells within Moewusinia clade, selected strains can be divided into four groups which coincide with molecular - phylogenetic clusters with high bootstrap support. Within each of the group the average length of the cell is the distinguished feature of the specific level. The size of the cell is the base for identification of Moewusinia clade strains in the slant culture.
