“…This can be due to indirect effects mediated through alteration of trophic interactions between populations of different species [12,13]. But more generally, this roots from "emergent" properties of ecosystems, like resilience or resistance, which drive to non straightforward propagation of effects across levels of biological organisation [14], or through successive generations [15,16].…”

Radioecology, a multifaceted scientific discipline which addresses environmental issues relevant to radioprotection, has for a long time been focused on environmental transfers through the environment to feed the needs of human radioprotection. This quite anthropocentric initial scope is now moving to a more ecocentric view capable of assessing ecological risk mediated by ionising radiation. The central issue consists in reaching an ability to understand the effects of radiation on the environment components, from individual organisms up to populations of species and ecosystems, together with their interaction with the abiotic compartments. Dominated by operational goals, the system of radiological protection of the environment which is under development emphasises a concept based upon reference organisms supported by traditional toxicological data on individual organisms. Whilst there are immediate advantages to this approach (pragmatism, consistency with other approaches in use for man and biota), there are also clear limitations which need to be acknowledged and further considered. The most important probably is to rely on effects data gathered almost exclusively for individual organisms to meet protection goals which are usually set at population and ecosystem levels. Overcoming this limitation leads to scientific and methodological approaches featuring the ecosystem concept. *

“…This microcosm was exposed to gamma rays, ultraviolet (UV) radiation, acids or metals, and effects on cell densities were observed [9]. Effects observed in the microcosm were not only direct effects but also indirect effects due to interspecies interactions.…”

Abstract. This paper summarizes research activities in National Institute of Radiological Sciences (NIRS) for evaluation of the radiation effects on selected terrestrial and aquatic organisms as well as the ecosystems. Seven organisms, conifers, fungi, earthworms, springtails, algae, daphnia and Medaka are presently selected to study. For the estimation of possible radiation dose, transfers of radionuclides and related elements from medium to organisms are evaluated. Dose-effect relationships of acute gamma radiation on the survival, growth, and reproduction of selected organisms have been studied. Studies on the effect of chronic gamma radiation at low dose rate were also started. In order to understand the mechanism of radiation effects and to find possible indicators of the effects, information of genome-and metagenome-wide gene expression has been collected. Evaluation of ecological effects of radiation is more challenging task. Study methods by using three-species microcosm were established, and an index for the holistic evaluation of effects on various ecological parameters was proposed. The microcosm has been simulated as a computer simulation code. Developments of more complicated and practical model ecosystems have been started. The Denaturant Gradient Gel Electrophoresis (DGGE) has been applied on soil bacterial community in order to evaluate the radiation effects on soil ecosystems.
