An understanding of the dose-effect relationships of ionising radiation for nonhuman biota establishes important baselines for the radiological protection of ecosystems. We used standard laboratory tests to examine the dose-effect relationships of gamma radiation on the survival, growth and reproduction of the earthworm, Eisenia fetida (Oligochaeta). Adult E. fetida were acutely irradiated with...
Background: Cardiovascular disease is one of the major leading cause of death in Iran. There is a strong association between parental history of cardiovascular disease clustering of risk factors in the offspring. Detection and treatment of cardiovascular risk factors since childhood is essential to reduce the incidence of disease in adulthood. This study was performed to identify major cardiova...
We provide descriptions, with illustrations of internal structures, for 18 new species of Pheretima from Mt. Malindang, Misamis Occidental Province, Mindanao Island, Philippines. Among the 18 species, 11 belong to the P. sangirensis species group, characterized by having a pair of spermathecal pores in the intersegmental furrow of 7/8 and lacking penial sheaths in the copulatory bursae: P. macu...
The diffusive oxygen uptake (DOU) of sediments inhabited by Chironomus riparius and Tubifex tubifex was investigated using a planar oxygen optode device, and complemented by measurements of bioturbation activity. Additional experiments were performed within contaminated sediments to assess the impact of uranium on these processes. After 72h, the two invertebrate species significantly increased ...
