In this connection, discussion is conducted about the question of the organisation of plant communities and whether it is possible to classify them.Īlechin W. The type of structural change corresponds to the ‘Non-linear and continuous’ - ‘Tendency for association’ model, and the pattern of distribution of plant species corresponds to the ‘Clustered distributions’ model of Scott (1974). Nevertheless, there are clearly recognisable leaps between, and a clear clustering of plant species within, the stands of the various community types. Variation in relief height produces a continuous change in the forest vegetation. The type of structural change is elucidated by means of a vegetation table, presentation of the frequency distribution of plant species, a contingency table, non-metric multidimensional scaling, a discriminant function and a cluster analysis. The investigation is based on 116 sample plots in all, each of 8 square metres in area. By contrast ceteris paribus conditions obtain for climatic relations and nutrient supply. It gradually changes within the transect according to relief height. The soil water conditions function as an independent variable of the physical-chemical environment, influencing the vegetation structure. The object under study was a 116 m long transect in the unspoiled flood plain forests of the Sava valley in Croatia, which contains stands of three widespread forest community types. To this end the local variation in vegetation structure along a continuously changing environmental gradient was studied.
The goal of the present study resides in the attempt to falsify the discontinuum hypothesis.
