By joining the European Union Slovenia is required to take on new environmental directives. Those concerning aquatic environments ane especially important and well prepared. Our research has therefore contributed significant new information on biodiversity of communities of flowing waters (especially of some macroinvertebrates) and on seasonal changes and longitudinal variations in relation to ecological variables etc. All of this is a basis for a different approach to the monitoring of Slovene water potential. Of special importance is the discovered fact that the terrestric part of the river bank is vital for the stability and diversity of the aquatic environment. The introduction of RHS methodology is a completely new approach for Slovenia and our results so far confirm that we are on the right path to evaluatind and estimating the impact on the environment. Results of the botanical, taxonomical and chorological research have increased our knowledge of the distribution and diversity of plant species in Slovenia. The findings have been included in the works Gradivo za Atlas flore Slovenije (2001) and Mala flora Slovenije (1999). The development of computer software for the quantitative analysis of images has enabled work also in other research groups in Slovenia as well as abroad. We have also acquired some basic findings about our forests that will help in their sustainable use and preservation. The findings of our research so far have a great impact for the protection and preservation of natural heritage, especially some rare and endangered orchids. The potential use of micorrhiza in biotechnological cultivating of herbacous plants and trees is also an important contribution. The potenctial use of micorrhizal symbiosis as a bioindicator of polution as an indicator of bioavailability of polutants for plants and funghi is of great environmental importance. The influences of the social and cultural environment are specific for each society because they are determined by their temporal, regional, cultural and social differences. This specific environment requires of each society to conduct research of its own which enables it to evaluate its secular development tendencies as well as regional differences, which are determined by social and economical development. In the second half of the twentieth century our research on growth and development of children was limited to the Ljubljana region. We believe that by extending our research area to other regions we explore this field in a much more complex way, because physical growth and development are sensitive indicators of the child's general fitness and health.
