ΔΟΜΗ, ΔΥΝΑΜΙΚΗ ΚΑΙ ΔΙΑΧΕΙΡΙΣΗ ΤΩΝ ΕΡΗΜΩΝ ΑΣΦΟΔΕΛΩΝ ΤΗΣ ΘΕΣΣΑΛΙΑΣ

THE AIM OF THIS DISSERTATION IS THE STUDY OF THE STRUCTURE AND DYNAMICS OF ASPHODEL DESERTS IN THESSALY AS WELL AS THE CONSIDERATION OF POSSIBLE SCENARIA OF DEGRADATION PROCESSES, BASED ON THE VARIOUS MANAGEMENTAL PRACTICES, LOWLAND PASTURES OF THESSALY. THEREFORE: THE FLORISTIC COMPOSITION OF ASPHODEL DESERTS IN THESSALY WAS RECORDED AS WELL AS ITS SEASONAL FLUCTUATIONS AND THE MEAN DENSITY (8 IND/M2) AND THE DISTRIBUTION PATTERN OF A.MICROCARPUS WERE DETERMINED. THROUGHOUT THE PERIOD OF A YEAR, THE PHENOLOGICAL CYCLE OF ASPHODELS PRESENT FOUR DISTINCT PHASES: THE MORPHOLOGICAL AND FUNCTIONAL FEATURES OF EACH ONE WERE FURTHER STUDIED. THE TOPICS DEALT WITH ARE: PLANT GROWTH ANALYSIS, DETERMIANTION OF NUTRIENTS CONCENTRATIONS, DETERMINATION OF CALORIC AND ASH CONTENT IN EACH PARTOF THE ASPHODEL AND OF THE STORAGE VOLUME OF THE TUBERS. THE EFFICIENCY OF ASPHODEL BOTH OF THE WHOLE PLANT AND OF ITS VARIOUS PARTS, TO EXPLOIT THE INCIDENTSOLAR ENERGY IN THE STUDY AREA WAS DETERMINED. THE PROCESS AND RATE OF CELLULOSE DECOMPOSITION WAS STUDIED AS WELL AS THAT OF THE ABOVE GROUND ASPHODEL PARTS. THE SOIL ANIMAL COMPOSITION WAS STUDIED AND WAS FOUND THAT THE MESOPHILIC GROUP OF THE SOIL ANIMALS PLAYS A PARTICALAR ROLE IN THE FUNCTION OF THIS ECOSYSTEM. THE SEASONAL FLUCTUATIONS OF SOIL LOSS WERE RECORDED DURING A PERIOD OF ONE YEAR. FINALLY COMPARING THE DEGREE OF SIMILARITY OF THE FIVE PLANT FORMATIONS OF THE WIDER STUDY AREA WE HAVE RESULTED IN THE POSTULATION OF THREE DIFFERENT SCENARIA CONCERNING THE DEGRADATION PROCESS OF THE LOWLAND PASTURES OF THESSALY.
