    Suitability of Drought-Preconditioning Techniques in Mediterranean Climate (2003)

    Notes: Abstract Arid and semiarid ecosystems in the Mediterranean are under high risk of desertification. Revegetation with native well-adapted evergreen shrubs is desirable, but techniques for successful establishment of these species are not fully developed. Transplant shock is a key hurdle to plantation success. The application of a drought-preconditioning treatment during the last months of nursery culture is a potential technique for reducing transplant shock. This technique has been widely applied in boreal habitats and humid temperate areas. Three representative Mediterranean species (Pistacia lentiscus, Quercus coccifera, and Juniperus oxycedrus seedlings) were exposed to classic drought-preconditioning treatment consisting of reductions in the watering regime. The effects of preconditioning on seedling quality were assessed by cell water relationships (pressure–volume curves), minimal transpiration, leaf capacitance, chlorophyll fluorescence, and gas exchange. Moreover, seedlings were exposed to transplant shock (intense drought period) during which water potential (predawn and midday) and maximal photochemical efficiency were evaluated to establish seedling performance. Results showed that preconditioning did not affect cell water relationships and minimal transpiration in any of the three species. Preconditioned seedlings of P. lentiscus maintained higher water content during desiccating conditions as a consequence of an increase in leaf water content at full turgor. These changes allowed plants to maintain higher net CO2 assimilation rates and an elevated photosystem II status, facilitating an increase in drought survival. Preconditioning improved the performance of Q. coccifera and J. oxycedrus seedlings, but these two species were much less responsive than P. lentiscus seedlings. Finally, results suggest that sensitivity to drought preconditioning may be related to drought tolerance or avoidance strategy of each species. Drought-related strategies should be considered to optimize management scale preconditioning.

    Assessing components of a competition index to predict growth in an even-aged Pinus nigra stand (1998)

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Abstract The relationship between tree growth and competition may depend on some subjective choices that are commonly left to the researcher. Among these are the neighborhood radius, the number of years of growth that are integrated, and tree age. We have evaluated the importance of these factors when relating growth and competition in a forest stand with contrasted densities of the dominant tree species (Pinus nigra) and understory shrub species (Adenocarpus decorticans). Previous to this evaluation we performed a randomization test to assess the relationship between tree growth and neighbors. By using Daniels index of competition we found that the use of a fixed neighborhood radius underestimated the importance of tree competition. The coefficient of determination (r2) of the relationship between tree growth and Daniels index increased asymptotically with the number of years considered. Five years of growth gave high r2 independently of the density of trees and shrubs. The intensity of competition was weakly affected by the characteristics of the plot (tree and shrub densities), and did not change with time. In contrast, the potential growth at equal competition – as represented by constant “a” in the allometric model – changed with time suggesting a gradual decrease in potential tree growth in the plots with higher tree density, and a gradual increase in those plots with high density of shrubs. These results may reflect tree canopy closure and the senescence of Adenocarpus decorticans. A method is suggested to select optimum neighborhood radius and growing period for the calculation of competition indices. By applying this method we were able to explain as much as 79–84% of the variability in tree growth of this stand.

    Saharan dust and the atmospheric inputs of elements and alkalinity to mediterranean ecosystems (1993)
    Springer
    Water, air & soil pollution 66 (1993), S. 277-288 
    Details
    ISSN: 1573-2932
    Source: Springer Online Journal Archives 1860-2000
    Topics: Energy, Environment Protection, Nuclear Power Engineering
    Notes: Abstract Saharan dust delivered by so-called ‘red rains’ strongly influences precipitation chemistry in the Mediterranean region. We show here that at rural sites in eastern Spain, red rains have much higher ion concentrations than non-red rains, and they account for up to 50% of the mean annual input of dissolved elements in bulk precipitation, though they make up only a minor part of the annual rainfall. The mean annual input of alkalinity in red rains is enough to neutralize the input of free acidity in acidic precipitation. Transport of Saharan dust is thus a major ecological force in Mediterranean ecosystems through its effects on the acid neutralizing capacity of the atmosphere and the atmospheric deposition of elements.

    Neutralization of Nitrate and Sulphate in Precipitation on the Eastern Mediterranean Coast of Spain. Implications for Acidification Risk (1998)
    Springer

    Notes: Abstract The results of two years of sampling in a network of 27 rainfall stations in the Valencian Community (Spain), show that most of the rain collected in the region, has a neutral or alkaline character, with a high mean concentration of calcium and sulphate in some of them. The network station distribution covers a range of distances from the sea, altitude, soil use and human activities (industrial, urban, agricultural). No correlation has been found between H+ and strong acidic anions (non marine sulphate and nitrate). Sulphate showed a high correlation with calcium. The spatial distribution of non marine sulphate, the ratio of marine sulphate to total sulphate, nitrate, calcium concentration and pH, showed that different concentrations of species are more related with geographical and meteorological characteristics than with proximity to industrial sources. The received amount of calcium and their neutralizing effect is used to predict the soil acidification risk in the area.

    Mapping Rain Composition in the East of Spain by Applying Kriging (1998)
    Springer
    Water, air & soil pollution 104 (1998), S. 9-27 
    Details
    ISSN: 1573-2932
    Keywords: kriging ; neutralization ; rain chemistry ; spatialdistribution ; western Mediterranean
    Source: Springer Online Journal Archives 1860-2000
    Topics: Energy, Environment Protection, Nuclear Power Engineering
    Notes: Abstract This paper presents the results of applying kriging to the major inorganic ions from a bulk deposition network on the eastern coast of Spain that has been in operation for more than two years (October 1989 to December 1992). From the calculated variograms spatial correlation up to 70–130 km has been found, depending on the ion. The most suitable models of variograms have been found for sulphates and marine ions (chloride, sodium). Nitrates and pH correlates only at smaller distances. For calcium and pH additional to the correlation at smaller distances, a correlation at distances around 140 km was found. The nugget effect was high for most variograms, suggesting the importance of local influences in rain chemistry in the area. In general, most of the ions follow a spatial pattern that gives the highest values in the south and the lowest in the north inland part of the area of study. It is possible to discern different spatial patterns according to the ions and their main sources: A pattern following the coastline with decreasing values from the coast to inland was followed by chloride, sodium, magnesium and nitrate ions; a pattern divided into four areas, two with pH 〈 6.2 and less than 220 μeq L-1 for calcium and another two zones that surpass these values. Finally total sulphate and non-marine sulphate follow a pattern half-way between the previous patterns.

    Litterfall as a measure of primary production in Mediterranean holm-oak forest (1992)
    Springer
    Plant ecology 99-100 (1992), S. 69-76

    Keywords: Holm-oak ; Mediterranean forest ; Quercus ilex ; Primary production ; Litterfall ; Litterfall nutrient contents ; Temporal variability
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract In this paper we discuss the use of litterfall as a method to measure primary production and its between year relation to climatic fluctuation. Seven years of study in a mediterranean holm-oak forest showed a moderate inter-annual variability of litterfall (C.V. 11%), while the annual variability of the actual evapotranspiration was three times higher (C.V.30%). Furthermore, the inter- and intra-annual variability of nutrient content in the various fractions are presented in relation to water availability. Monthly and seasonal variability was higher than the annual variability for all analyzed elements.
