Cel To measure the biodiversity across the ecotone pineforest-Mediterranean open shrubland in degraded Mediterraneanareas, and to understand the changes across the ecotone. Todetermine the role of soil organisms in soil creation in thespecified ecotone. Subsequently, to understand the relationbetween the soil macromorphological units of organic matter andtheir associated organisms; and to determine how the soilorganisms from the ecotone can contribute to the soil creationand to erosion reduction, thus assessing the useability ofecotone effect to reduce erosion.Two selected, similar areas meeting the following conditions: (i)be located in different geographical areas subject to soildegradation and erosion subsequent to land abandonment and/orformer management; and (ii) include the transition betweenmature, reafforested pine stand and open Mediterranean shrubland,will be integrally studied. The primary data obtained from thesites will be: (i) soil type and composition; (ii)macromorphological soil units (MUs) characterization; (iii)phytosociological and ecological characterization of theecotones; and (iv) MUs' taxocenoses of edaphic microarthropods(Acari and Collembola) and Nematoda.The sampling of soil organisms will be made by a non-disruptivemethod (Kubiena boxes) with in-situ instant preservation thatwill allow their exact location within the soil units. The MUswill be separated and their fauna extracted by a chain of manualscan/heptane flotation/saccharose centrifugation. The animalswill be classified by taxonomists to species level wheneverpossible. Some animal groups will be extracted byBerlesse-Tullgren method. The gut contents of Collembola will beanalyzed after animal classification.The organic matter of the MUs will be analyzed for carbon,nitrogen, and humic and fulvic acids. The soil will bepedologically profiled and chemically analyzed. The vegetationwill be taxonomically and phytosociologically analyzed across thetransects and within the defined areas of pine and shrubland,including cartography.All generated bionomical data will be managed by aspecial-purpose faunistic/ecological database (ZOOTRON 4). Thebiodiversity profiles and other ecological data will becalculated across the ecotone for all groups. The relationbetween MUs, organic matter, vegetation, soil type and soilorganisms will be statistically calculated and functionallydetermined from affinity or association matrixes. The possiblerole of the ecotone in the soil creation/regeneration will beestimated from these analyses. If results are positive, theecotone width will be determined in order to provide forestrymanagement recommendations for erosion reduction.
