The aim of this study was to determine the current level of atmospheric heavy metal content on the Bozdag Mountain of the Aegean Region, Turkey. Twenty nine different plants were selected to study their potential as biomonitors of trace elements such as Ni, Zn, Fe, Pb, Mn and Cd (?g g-1, dry weight). The samples were collected from two different altitudes of Mt. Bozdag. The concentrations of trace elements were determined by atomic absorption spectrometry. The mean concentrations determined at 1000 m altitude ranged from 0.025 to 1.609, 0.232 to 0.731, 0.578 to 5.983, 0.287 to 0.565 and 0.176 to 2.659 (?g g-1, dry weight), for Ni, Zn, Fe, Pb and Mn, respectively. At the altitude of 1600 m, the values ranged from 0.023 to 0.939, 0.258 to 1.254, 0.839 to 5.176, 0.301 to 1.341 and 0.405 to 3.351 (?g g-1, dry weight) for Ni, Zn, Fe, Pb and Mn, respectively. No Cd was detected at either altitude. Statistical significance was determined by the independent sample t-test and comparisons were made in order to determine if there were any differences between the averages of herbaceous and woody plants. .

Studies devoted to artificial reclamation and natural renaturalization of the open cuts are important because of the distribution of the nonmetallic open-cut mining in the Middle Volga. The following article contains the results of floristic and geobotanical study of the Ust-Sokskiy quarry, where the secondary plantation has been forming for the last 40 years after calciferous stock mining and quarrying. At present overgrowing Ust-Sokskiy quarry is used as a natural testing field for exploration of the secondary anthropogenic successions, ecological, anatomical, morphological, physiological, biochemical and biogeochemical peculiarities of plants. 107 species of the vascular plants belonging to 83 genera, 35 families, 5 classes and 4 phyla were fixed in the quarry. 6 species from the Red Book of Samara Region were found in the composition of the local flora. Species penetration to the quarry is realized by dissemination from the nearest natural phytocenoses of Sokolii Mountains. Local flora of the quarry is significantly poorer than that of the Sokolii Mountains and differed by species composition that is explained by abiotic conditions specifics which are inherent to the technologically disturbed territory. Herbaceous and woody plants of the quarry are characterized by depressed vital condition. Modern local flora of the quarry is unbalanced and the process of its forming is continued.

The vegetation of dolomitic outcrops was sampled in a maple forest of southern Quebec. Multivariate analyses have demonstrated the influence of rockiness and size of outcrop on the distribution of herbaceous and woody plants. These results allow the description of five microcommunities. The flora of small cracks and hollows is exclusively herbaceous and of low diversity. Deeper soils support tree seedlings and saplings (mostly Acer saccharum) and also a diversified herbaceous stratum. The chemistry and mictotopography of outcrops produce mesic soils, rich in organic matter and nutrients. Soil depth segregates among plant species according to the size of their roots. Big outcrops have a more favorable microclimate. Dolomitic outcrops found in maple forests are biogeochemically rich microhabitats, which may support a more varied and abundant vegetation than does the surrounding forest floor. Primary succession on these outcrops is briefly discussed.

The paper presents study results of 8 herbaceous and woody plants species assimilating organs biochemical parameters in conditions of introduction. It has been identified that in 4 herbaceous introduced species increased chlorophyll content and ratio of chlorophyll to flavonoids in August is associated with massive flowering and fruiting phases. On the contrary, in Crataegus ellwangeriana the maximum values of the above parameters are the reaction to unfavorable growing conditions (lack of nutrition and moisture) during the active growth period. The increased anthocyanins synthesis in Physocarpus opulifolius and Sorbaria sorbifolia by 1,2-1,4 times and increased nitrogen balance in Aronia melanocarpa up to 23 mg/cm in September compared to summer period testifies to protective function formation in plant organism in pre-winter period. Slight fluctuations in flavonoids content throughout the entire vegetation season confirm that all the studied plants are in optimal nitrogen status. The following statistical methods were used to interpret the present study results: Shapiro-Wilk W-test (for small samples n 30), parametric analysis method Students t-test, t-test for dependent samples.

In August 2000, several small galls were observed on roots of lady's mantle (Alchemilla acutiloba Opiz) from an old grassland near Kristiansund in northern Norway. These plants, without clear above-ground symptoms, were infected with an unknown root-knot nematode. Soil and plant samples were collected in July 2001 at the previous year's location and sent for identification to the Plant Protection Service in Wageningen, the Netherlands. The smooth elongated galls included several males, swollen adult females with protruding small egg masses and hatching second-stage juveniles. Males and second-stage juveniles also were isolated from adhering soil. The root-knot nematode was identified as Meloidogyne ardenensis Santos (1). Identification was based on female, male, and second-stage juvenile morphology and female isozyme electrophoresis with malate dehydrogenase and esterase. M. ardenensis parasitizes several dicotyledonous hosts, primarily herbaceous and woody plants, and is distributed throughout Europe, with Scotland the most northern area (2). To our knowledge, this is not only the first published report of M. ardenensis in Scandinavia, but also the first report of this species on lady's mantle. References: (1) M. S. N. de A. Santos.
