Continuous long-term monitoring is important for detecting ecological changes and understanding their causes, including anthropogenic impacts such as climate changes and eutrophication. Nonetheless, such long-term population studies have been rare, e

Interactive toxic effects between heavy metals were investigated using a sea urchin (Anthocidaris crassispina) bioassay. An effluent from an abandoned mine showed significant inhibitory effects on embryo development as well as producing specific malf

Around the western part of Teshima Island in Kagawa Prefecture, various types of industrial waste were dumped illegally for about 20 years. The dumped wastes amount to a total of approximately 500,000 tons. The biological monitoring of coastal seawat

The toxicity of the polluted waters originating from a disused lead mine was evaluated using both sea urchin bioassays and heavy metal analysis. Samples from three polluted waters (a seawater and two freshwaters) were collected from the mine area and

Sea urchins (fully mature: large, mature: medium and maturing: small) were cultured for 2 weeks in seawater containing nonylphenol (NP). The GT ratio (=100·gonad volume/test volume) was measured for all sea urchin samples that were then classified i
