The emission of a specific blend of volatiles in response to Mythimna separata (herbivore-induced plant volatiles, HIPVs) plays a great ecological role by priming neighbouring plants. Maize plants placed downwind of infested, conspecific plants showed reduced larval development not only immediately after exposure to HIPVs but also when receiver plants were(More)
Exposure of tomato plants to volatile chemicals emitted from common cutworm (Spodoptera litura)-infested conspecifics led to accumulation of the glycoside, (Z)-3-hexenyl vicianoside. Accumulation of (Z)-3-hexenyl vicianoside in the exposed plants has adverse impacts on the performance of the common cutworms. The aglycon of (Z)-3-hexenyl vicianoside is(More)
In Lake Tega, Japan, the shift of dominant algal species was caused as a result of discharging water from the adjacent river into the lake. The transition from cyanobacteria (mainly the genus Microcystis) to diatoms (mainly the genus Cyclotella) resulted in a disappearance of algal blooms. Although some environmental conditions such as flow rate, nutrient(More)
