The following paper deals with the ecological and coenotical structure of the Regional Natural Monument Chelyabinsk city pine forest vegetation. The estimation was done by a cluster analysis with Sorensen-Chekanovsky (Bray-Curtis) distance measure and a flexible beta group linkage method - by non-metric multidimensional scaling, phytoindication and general discriminant analysis algorithms. The flora and coenotical structure of Chelyabinsk city pine forest plant communities are characterized by significant anthropogenic transformation. Forest-margin and meadow, ruderal and synanthropic species are insinuating and naturalizing in pine forest communities actively and supplanting typical pine forest species off communities. The studied pine forest flora synanthropic index is 32 percent. 15 plant associations were detected; its flora, dominant and constant species, coenotical structure and biotopes were characterized by principal ecological factors. The biotopes series of ecological factors replacement were identified. Biotopes series are specified by forest stand ecological structure, that determining ecological regime changes from semi-light to semi-shade and from more arid to more damp. Also biotopes form series from wet more variable moistening bad-aerated not-acid and salt enriched soils to acid aerated poor soils with contrast arid moistening. The detected Chelyabinsk city pine forest biotopes are characterized by not so fluctuation of principal ecological factors.

Mogutova mountain flora (Zhiguli hill, Samara Region) has about 700 species of vascular plants, 14 species are included in the Red Book of the Russian Federation (2008), 50 species are included in the Red Book of the Samara Region (2017), 7 species are the endemics of the Zhiguli hills. On the Mogutova mountain 48 plant associations were described: 36 associations are represented by forest vegetation, 1 Association is represented by shrubs, 11 associations are represented by herbaceous vegetation. In eight described associations there are 6 endemic species of the Zhiguli hills: in Cerasus fruticosa + Caragana frutex association one endemic species is found - Euphorbia zhiguliensis; in Stipa pennata - Caragana frutex association there are 3 endemics - Cerastium zhigulense, Gypsophila juzepczukii and Thymus zheguliensis; in Stipa capillata + Herbae stepposae and Stipa capillata + Echinops ruthenicus associations there is only Thymus zheguliensis; in Herbae stepposae + Stipa pulcherrima and Stipa pennata + Helianthemum nummularium associations there are 2 endemic species - Gypsophila juzepczukii and Thymus zheguliensis; in Thymus zheguliensis association there are 4 endemics - Cerastium zhigulense, Gypsophila juzepczukii, Sisymbrium pinnatisectum, Thymus zheguliensis; in Schevereckia hyperborea association Poa saksonovii is revealed. The endemics of the Zhiguli hills: Euphorbia zhiguliensis and Thymus zheguliensis are protected at the Federal level, and Cerastium zhigulense, Gypsophila juzepczukii and Poa saksonovii are protected at the regional level.

Successional Stages

Intensive studies of soil and vegetation were performed in Rivière-du-Loup County to identify various plant associations of meadows and pastures, describe the successional trends of each ecological habitat and establish a relationship between plant associations and various environmental factors. After vegetation survey and analysis, four plant associations and their successional trends were described. Each plant association was identified by the dominant species at the most advanced stage of secondary succession: (1) red fescue-bent grass association, (2) red fescue-Lindberg’s plume moss association, (3) bent grass–red fescue association, and (4) poverty grass–mouse-eared hawkweed association. All four plant associations were distributed in space according to the physiography and nature of the soils. Vegetation was highly influenced by age of sites. Young meadows and pastures were dominanted by timothy, red top, white clover and Canada bluegrass. Red fescue was very important on all 10 yr-old sites and remained so in all successional stages except in bent grass–red fescue and poverty grass–mouse-eared hawkweed associations. Vegetation changes with age depended on both ecological factors and land utilization. The results suggest that intensive soil studies and a rapid survey of vegetation would have provided results very similar to those obtained by a very detailed ecological study.

Forest typological and phytososological biodiversity of forest vegetation of Slobozhansky National Park is shown. The park covers 5244 hectares and includes the main parts of the run off valleys of the left-bank Merla River tributary, which belongs to the Vorskla River basin in the Kharkiv region. The main forest-forming species of the Slobozhansky National Nature Park are Pinus sylvestris L. (2779.3 hectares, 59.84%), Quercus robur L. (1451.8 hectares, 31.26%). Minor areas are occupied by Betula pendula Roth (138.3 hectares, 2.98%), Alnus glutinosa (L.) P. Gaertn. (122.5 hectares, 2.64%), Populus tremula L. (45.0 hectares, 0.97%) and other species. Areas covered with forest vegetation are represented by 16 edatopes: all trophotope and almost all hygrotopes, except very dry. Among the trophotopes subors (2015.2 hectares, 43.39%), oak wood (1504.4 hectares, 32.39%) and sugruds (1042.2 hectares, 22.44%) predominate, and the part of pine forest is insignificant (82.5 hectares, 1.78%). Among hygrotopes, the majority are with fresh conditions (4060.6 hectares, 87.43%), much smaller areas are dry (268.4 hectares, 5.78%), damp (184.3 hectares, 3.97%), moist (124.4 hectares, 2.68%) and wet (6.6 hectares, 0.14%) conditions. There are 17 types of forests in the Slobozhansky National Park areas covered with forest vegetation. Fresh oak-pine forest (1780.6 hectares, 38.35%), fresh maple-linden forest (1453.6 hectares, 31.30%), fresh linden-oak-pine sugrud (756.8 hectares, 16.30%) are dominated. Pinus sylvestris plantations grow in 10 forest types. The most common types of pine forests are fresh oak-pine and fresh linden-oak-pine sugrud. Quercus robur growth in 7 forest types, the most common of which is fresh maple-linden oak wood. The distribution of forest typological differences on the territory of the park of vascular plants rare species populations, which have different sozological status is analyzed. Annex I to Resolution 6 of the Berne Convention includes the following species: Dracocephalum ruyschiana L., Jurinea cyanoides (L.) Rchb., Iris pineticola Klokov. A number of species have the appropriate conservation status in Ukraine (Diphasiastrum complanatum (L.) Holub, Lycopodium annotinum L., Dracocephalum ruyschiana, Pulsatilla pratensis (L.) Mill. Sl, Allium ursinum L., Iris furcata M. Bieb., Iris pineticola, Fritillaria meleagris L., F. ruthenica Wikstr., Tulipa quercetorum Klokov & Zoz, Epipactis helleborine (L.) Crantz, Listera ovata (L.) R. Br., Neottia nidus-avis (L.) Rich., Platanthera bifolia (L.) Rich., Stipa borysthenica Klokov ex Prokudin) and 22 species at the regional range.

The purpose of this study was to survey the Angiosperms from an area of Caatinga, in the Grota do Angico Natural Monument, state of Sergipe, Brazil. A total of 174 species and 51 families were registered. Fabaceae (29 species) is the family with the highest number of species, followed by Asteraceae (11), Euphorbiaceae (10), Malvaceae and Poaceae (9 each) and Rubiaceae (8), Bromeliaceae, Cactaceae and Convolvulaceae (7 each). Most species are herbaceous (55.2%), followed by trees (20.7%), shrubs and vines (7.5% each), subshrubs (6.3%), epiphytes (1.7%) and hemiparasites (1.2%). Approximately 17% (30 species) of the flora are endemic to the Caatinga, one species is rare and two are vulnerable. Our results reinforce the importance of conserving the remaining forest vegetation against the anthropic pressure.
