“…Among the components of biodiversity, some taxonomic groups, such as insects, are relatively tolerant of radiation exposure [ 15 – 17 ], and serious effects of exposure to radiation within the Fukushima evacuation zone are unlikely to be found at the population level [ 11 ]. A previous study that surveyed the northwestern area of the Fukushima nuclear power plants immediately (6 months) after the accident suggested that the reduction in the abundance of insects exposed to radiation was less obvious than that it was at Chernobyl [ 10 ].…”

Pollinators and Other Flying Insects inside and outside the Fukushima Evacuation Zone

Following the accident at the Fukushima Daiichi nuclear power plants in 2011, a large evacuation zone was imposed in an area where residents had historically managed forests and farmlands. Thus, the human activities that had maintained biodiversity and ecosystem services in the zone were discontinued. Such change can affect insects, a biodiversity component that is relatively tolerant to radiation exposure. In this study, we investigated flying insects, including pollinators, important ecosystem providers inside and outside the zone, using Malaise traps. The results showed that the number of individuals of Xylocopa appendiculata, the largest Apidae species in the region, was significantly lower inside the evacuation zone than outside it, whereas those of other insects were not lower significantly. Although we suggest that flying insects and their ecosystem services (i.e., benefits from them such as pollination) 3 years after the disaster were not critically impacted, it is important to monitor the long-term effects of the evacuation in the future.

“…There have been a few such studies in reactor waste disposal sites (Blaylock, 1966;Davis & Foster, 1 9 5 0 , but these have usually been concerned only with genetic changes. More recently Odum & Pigeon (1970) have published the extensive studies of the irradiated El Verde rain forest and Styron & Dodson (1973) studied arthropod populations in a simulated radioactive fallout area. These studies have either involved genetic changes in the exposed populations or changes in insect abundance and diversity.…”

Abstract. 1. Population dynamics of Ips calligraphus and I. grandicollis (Coleoptera: Scolytidae) were studied in a forest exposed to high doses of gamma radiation. 2. Populations were replicated at eleven dose rates by using ‘trap logs’. 3. Adult beetles did not avoid high radiation intensities and attacked all sites equally. 4. Utilization of the cambium‐inner bark area varied from c. 2% at a dose rate of 2520 R/20 h day to 90% at dose rates of 63 and 105 R/20 h day. 5. Developmental success of the new brood was directly dependent on the dose rate, and developing progeny were often killed by accumulated exposure. 6. Larger, slower developing species of subcortical beetles were eliminated at dose levels that allowed successful development of the two species of Ips bark beetles.

Patterns of movement of radioactive carabid beetles

Tracking of individual Ir-labeled ground beetles released in the field revealed that both the day-active and night-active species studied showed periods of small distances covered per day in random directions, alternating with periods of directed movement with large distances covered per day. This pattern occurred not only in the reproductive period but outside the breeding season as well in juvenile Pterostichus versicolor and spent Calathus melanocephalus. Although mean locomotory activity increased with temperature, great daily differences occurred between individuals, pointing to asynchronous behavior. In an unfavorable habitat directed movement occurred both more frequently and more extremely, sometimes resulting in escape to more favorable areas. Most of the radioactive beetles died within 7 weeks due to radiation effects, but independent field experiments and simulations showed that the recorded patterns were valid. Simulated individuals of P. versicolor living on 1 ha spread over 49 ha, whereas simulated C. melanocephalus covered only 9 ha after one activity season. Normal locomotory activities lead to both exchange of individuals between subpopulations and dispersal out of the habitat. The significance of these phenomena for population stability and for the survival of the species is discussed.
