Feeding deterrence of Azolla in relation to deoxyanthocyanin and fatty acid composition (2002)
Cohen, Michael F., Meziane, Tarik, Tsuchiya, Makoto, Yamasaki, Hideo
Higher levels of deoxyanthocyanins in Azolla fronds correlated with feeding deterrence against adult Lymnea swinhoei snails and Polypedates leucomystax tadpoles. After 7 days in co-culture, the...
