We researched the vegetation of the protected lower part of the Prodarjeva Grapa gorge in the foothills of Mt. Porezen in the upper Bača Valley. Its botanical curiosities are the localities of protected or rare species Moehringia villosa, Pri­mula auricula,Pinguicula vulgarisand Carex frigida. All four occur (but are not limited to) on the rocky and gra­velly shady area in the lower part of the gorge with a distinctly cold local climate. The relief, climate and parent material (platy limestone with admixture of marlstone and chert) are the decisive factors that allow for the occurrence of the previously unknown community of wet spring areas, which we classify into the new association Pinguiculo vul­garis-Cari­cetum frigidae, alliance Cratoneurion commutatiand class Montio-Cardaminetea, in this area. It is syndynamically connected with surrounding communities of wet screes and rock crevices. Screes under the rock wall are partly overgrown with a community of Molinia arundinaceaand Adeno­styles glabra (Adenostylo glabrae-Molinietum arundinaceanom. prov.), on the fringes in places also with an open low-growth hop-hornbeam and manna ash forest (Palustriello commutati-Ostryetum carpinifoliaenom. prov.).

Abstract The structure of raspberry cultivars and genetic resources in the Baltic countries have been influenced by the historical political situation in the 20th century and climatic conditions, especially winterhardiness. The genetic resources consist of some old European and American cultivars, but mostly of cultivars and hybrids bred in Russia. Currently, targeted breeding programmes are active only in Estonia and Latvia, which aim to develop winterhardy, disease-resistant cultivars, well adapted to the local climate. Therefore, parent material for hybridisation has been chosen from local advanced hybrids and introduced cultivars suitable to the regional climatic conditions. The aim of the study was to estimate the level of genetic diversity of Rubus germplasm and assess inter-specific and intra-specific relationships using phenotypical characterisation and molecular markers. Forty one Rubus genotypes were evaluated by 41 phenotypical traits and 15 previously described SSR markers. Both characterisation approaches discovered high correspondence with pedigree and a low level of diversity. A limited amount of the diversity of raspberry genetic material has been used in various breeding programmes, despite their broad geographical origin. The obtained results indicate the need for including local wild R. idaeus plant material into breeding programmes.

With a phytosociological analysis of more than 200 relevés on more than 25 localities with Gladiolus palustrisand (or) G. illyricusin western and southwestern Slovenia we identified more than 15 communities of association rank that belong to at least eight vegetation alliances and five classes. We determined that these two species can grow on the same localities and sites, but Gladiolus palustrisflowers at least 14 days after G. illyricus. Another reliable distinguishing characteristic is the fibrous tunic covering the corm. Gladiolus palustris is threatened in most of the examined localities, except for the Banjšice Plateau and the Slavnik range in Čičarija, but the current nature conservation policy in Slovenia does not provide for its preservation.

Ugotovili smo, da obe podobni vrsti lahko uspevata na skupnih nahajališčih in rastiščih, toda vrsta Gladiolus palustriscveti vsaj 14 dni kasneje kot vrsta Gladiolus illyricus. Zanesljiv znak za njuno razlikovanje so vlakna, ki obdajajo njun gomolj. Na večini preučenih nahajališč je močvirski meček ogrožen in mu zdajšnja naravovarstvena politika v Sloveniji ne zagotavlja ohranitve, izjema sta planoti Banjšice in pogorje Slavnika v Čičariji.

Existing Data

In the Čepovan Valley (Čepovan, hamlet Šulgi), on the northwestern rim of the Banjšice Plateau in the villages of Grudnica (in the Tolmin municipality) and near Sveto to the south of the plateau, we found new localities of Thlaspi sylvestre (T. caerulescens), which complement the existing data on the distribution of this species in Slovenia (Srednji Lokovec, Vrata), and surveyed its sites. Thlaspi sylvestre grows on meadows and pastures in the vicinity of human settlements, in hedges, on road banks, on the forest edge and in an open pioneer forest. Its most common companions are Galium mollugo agg. (G. album), Cruciata glabra, Rumex acetosa, Ranunculus acris, Taraxacum sect. Ruderalia and Veronica chamaedrys. Thlaspi sylvestre most frequently occurs in the communities from the class Molinio-Arrhenatheretea. Our findings confirm Tone Wraber’s assumption that it is not indigenous to Slovenia, and was introduced to the Banjšice Plateau as well as to Grudnica and the Čepovan Valley with human assistance (military transport during World War I).

Potrjujemo domnevo Toneta Wraberja, da ta vrsta v Sloveniji ni samonikla in da se je na Banjšice in tudi v Grudnico in Čepovansko dolino priselila s človekovo pomočjo (vojaškimi transporti med prvo svetovno vojno).  Ključne besede: fitogeografija, fitocenologija, Thlaspi caerulescens, florula castrensis, Čepovanska dolina, Grudnica, Banjšice, Slovenija

AbstractCladium mariscus (L.) Pohl (Cyperaceae) is a rare species in Europe considered by several authors to be a relict of the early Holocene period. It is listed in the Red Data Book of Ukraine, Annexes of the Habitat Directive and the Bern Convention. Communities with domination of this species are included in the Green Data Book of Ukraine. Substantial differences in major ecological factors for Cladium mariscus communities in the western (carbonate bogs) and the southern (marshes and floating swamps of the northern Black Sea) regions of Ukraine were shown. The author carried out comparisons of relevés characterizing different communities with Cladium mariscus within Europe. Based on the results of TWINSPAN analysis, four associations were identified, confirmed by floristic indices and ecological data: Cladietum marisci Allorge 1921, Soncho maritimi-Cladietum marisci (Br.-Bl. & O. de Bolòs 1957) Cirujano 1980, Dorycnio recti-Cladietum marisci Gradstein & Smittenberg 1977 and Junco maritimi-Cladietum marisci (Br.-Bl. & O. de Bolòs 1957) Géhu & Biondi 1988. Thus, in addition to the association Cladietum marisci, a new one was indicated for Ukraine, Junco maritimi-Cladietum marisci.

Local Soil

Soil plays in integral role in our terrestrial ecosystems. It is the membrane between the atmosphere and the biosphere. Soils provide a medium for vegetation, a filtration system for water, and contain the essential minerals and nutrients plants require (ref). Soil is composed of living (biotic) and non-living (abiotic) material. Soil development is a dynamic and ongoing process that depends on local climate, parent material, topography, vegetation, and time. The size of the inorganic mineral particles within a soil is referred to as grain size. Soil grain size is classified as Clay if the particle diameter is <0.002 mm, as silt if it is between 0.002 mm and 0.06 mm, or as sand if it is between 0.06 mm and 2 mm (Figure). The texture of a soil, or the distribution of particle grain size, can be a determining factor on how the soil drains or retains water, and its ability to retain nutrients, and its susceptibility to erosion, all of which can be direct factors in the development of natural vegetation or crop suitability. To classify a particular soils texture the proportions of particle size (% Sand, % Silt, % Clay) of a given sample is required. The use of a standard method is essential in order to compare data obtained at different locations (ref). A well-developed method for determining the quantitative proportions of particle size is the hydrometer method. Additionally, local soil conditions, or infrastructure (Roads) can have a direct impact on the water quality, specifically the turbidity of local water. The quantitative measure of sediment with water is known as Total Suspended Sediment, and can be related to other water quality measures such as conductivity. Total suspended solids is determined by filtering a known volume of water and measuring the mass of the suspended material that is captured on a fine filter.

Improve Reliability

In order to estimate the reliability of soil information presented in a detailed soil survey (1:20 000 scale) conducted in a flat terrain (Vercheres county, Quebec), 35 randomly selected delineations were inspected with 10 sites per delineation. Reliability was evaluated according to parent material (marine, estuarine and fluvial) and kind of map units (simple and compound). As a whole, mineral soils have been mapped and defined reliably for most criteria commonly used in soil interpretation systems. Reliability of soil information differed significatively with parent material. Taxonomic purity of marine, fluvial and estuarine soils delineations were 70, 58 and 28%, respectively. Although less precise, compound map units were more reliable than simple map units. Among the 13 soil variables studied, A and B horizons texture, B horizon designation and depth to carbonates were the more frequently in error. Results finally indicated that reliability is also a function of the delineation area and inspection density. In order to improve reliability of soil information and accelerate soil survey in future projects, it is suggested to adjust inspection density according to parent material, to reduce the number of classes for a few variables and to avoid excessive use of soil series'variants and delineations of small size (< 4 ha). Key words: Reliability, purity, accuracy, soil survey procedures, inspection density

The Relationship

The Relationship between Dissolved Solids Yield and the Presence of Snow cover in the Periglacial Basin of the Obruchev Glacier (Polar Urals) during the Ablation SeasonHydrochemical investigations were carried out in the periglacial basin of Obruchev Glacier (Polar Urals, Russia) in order to provide a quantitative and qualitative comparison of dissolved solids yields during the ablation season with and without snow cover taking into account the mineral composition of rocks and deposits occurring in the studied area. The concentration of dissolved solids in the waters of the investigated basin is very low (about 7.0-8.9 μS cm-1). It is most of all due to harsh local climate conditions as well as the presence of minerals resistant to weathering in the parent material. Both factors contribute to the low rate of chemical weathering in the area. Results obtained indicate that a larger dissolved solids yield was transported during the period with snow cover (106 kg km-2day-1, on average), than at the same time of the year but without snow cover (13 kg km-2day-1, on average) indicating that melting snow is an important factor influencing the yield of dissolved solids in surface waters.

Climate Action

Community Energy Planning (CEP) is a process that allows municipalities to develop and implement local climate action, meet carbon reduction goals, and ensure a steady supply of clean energy. This MRP compares CEP in four municipalities in Ontario and British Columbia, to examine the reasons that led municipalities to undertake CEP and the roles that the municipalities undertook in the process. By using a policy comparison and interviews with Subject Matter Experts, the role that the municipality played to develop and implement CEP, and the role of the CEP within the community were evaluated. The municipalities studied were seen to have undertaken the expected roles to varying degrees and with various methods. Key Words: An article on energy and emissions planning in Canadian municipalities, used the key words: community energy planning, climate action, energy policy, local environmental planning
