International audience | The implementation of Nature-based Solutions (NBS) in cities has shifted to an integrated approach paradigm, raising the need for a shared, explicit and formal representation of knowledge on NBS in urban water management. A solution is building an ontology: it is a representation that merges data and expert knowledge, prevents miscommunication, handles heterogeneous data types and formats, and can draw inferences. The ontology we present here was focused on describing a water treatment chain (core ontology), classifying NBS (notably Treatment Wetlands (TW)) and treatment mechanisms. Its construction has mobilized expert knowledge, existing ontologies and explicitation of relations between concepts, sometimes from different knowledge domains: technical, geographical, socio-environmental. The ontology is not only for description of NBS in urban water management, but also for better future database structuration and modelling purposes (for predictions in a decision-making support tool). The ontology will improve from iterative expert feedback.

2002
Schubert, R. | Muller-Starck, G. | Metzger, H. G. | Riegel, R. (Technical University of Munich, Freising (Germany). Weilhestephan Center of Life and Food Sciences)
The chloroplast genome has been widely addressed to describe genetic diversity in tree species with regard to phylogeographic studies. In contrast, there is little information on the pattern of genetic differentiation in tolerant and sensitive tree populations, responding to different types of environmental stress. The results demonstrate that chloroplast microsatellites markers are useful tools for elucidating and for testing the pattern of genetic differentiation in stress-exposed populations of Norway spruce, offering to prove the feasibility of marker-aided selection in future

2002
Sarvas, M. | Tucekova, A. | Seben, V. (Forest Research Institute, Zvolen (Slovak Republic))
Fertilization plays an essential role in forest management on the site being under air pollution load in last years. The soil acidity due to the acid fall-out is markedly worse and at the same time the concentration of calcium, phosphorous, potassium and magnesium are decreasing. The fertilization besides positive influence on height increment could help in adaptation process of plants establishment after transplanting and it can eliminate negative ifluence of anthropogenic conditions of the environmnet

2002
Zanini, E. | Caimi, A. | Santoni, S. | Bonifacio, E. (DIVAPRA-Chimica Agraria, Grugliasco (Italy))
45 sites were selected and sampled on the transects and according to the first results of the spatial analysis, 15 more sites were added where useful for the optimal interpolation. Topsoils were sampled including both the soil organic horizons and the more superficial mineral horizon, frequently E, if reached. The depth of the organic horizons, the grass cover, ranked by its hydrophilic character, related to the incipient hydromorphy visible where Norway spruce is more declining, and the Norway spruce health status were systematically recorded

2002
Raben, G. | Symossek, F. | Katzschner, W. | Gemballa, R. | Karst, H. | Kohler, S. | Nowatzki, O. (Saxon State Institute of Forestry, Pirna (Germany))
Taking into account the results of environmental monitoring in forest ecosystems (European Level I- and II-Programme) showing high degrees of soil acidification and still a widespread exceedance of critical loads by deposited sulphur and nitrogen compounds, the programme of differentiated forest protection liming should continue with site specific doses. On the other hand the programme to restore forest ecosystems with higher stability and to a large extent balanced nutrient cycles has to be carried out in order to minimize internal acid-generating processes

2002
Godbold, D.L. (University of Wales, Bangor (United Kingdom). School of Agricultural and Forest Sciences) | Fritz, H.W. | Cudlin, P. | Bonifacio, E.
Fine root distribution was estimated in three spruce stands with different stages of forest decline. At all 3 sites in the 0-5 cm layer the density of living fine root mass exceeds the necromass. However, in the deeper soil layer necromass exceeds biomass by a factor of 2-4 at Modry Dul, ca. 3 at Alzbetinka and by more than 8 at Mumlavska Hora. The distribution of root density was reflected in the distribution of root length and the number of root tips in each soil layer for the 3 sites
Mostrar más [+] Menos [-]Depositions from precipitation in the forest ecosystem of pedunculate oak and their possible impacts on the stability of the lowland forests in Croatia
2002
Tikvic, I. (University of Zagreb, Zagreb (Croatia). Faculty of Forestry) | Seletkovic, Z. | Sojat, V. | Znidaric, G.
The paper deals with the results of chemical analyses of the precipitation collected with the bulk method in and out of the pedunculate oak forest near Lipovljani in Croatia, for the period 1997-2001. A considerable higher total annual deposition of the majority of analysed determinants has been found in the forest. The results point to the importance and influence of the forest cover on the reception and distribution of dry and wet pollution in the forest ecosystem of pedunculate oak

2002
Kozlov, M.V. (University of Turku, Turku (Finland). Section of Ecology)
Impacts of big polluters on adjacent ecosystems can be seen as long-term unintentional experiments. Contrary to the common guess, results of these experiments may be used to address basic ecological problems, like diversity - stability and diversity - productivity relationships, as well as evaluate general effects of disturbance on ecosystem structure and functioning. Toxicity of pollutants plays a leading role at early stages of forest decline, while transformation of forests into birch woodlands and industrial barrens is accelerated by positive feedback's acting primarily via changes in microclimate
