Discussion

  • tN data has been adusted such that they are monotoneous

Facts

  • D.leuchtenbergianum: W in mug = 5.0713 (L in mm)^1.0456 (no eggs) (Ref: CulvBouc1985)
  • 3-4 juvenile instars in females (Ref: Boik2005)
  • dry-weight: ln (W in mug) = 1.023 + 2.099 * ln (L in mm) (Ref: LemkBenk2003)
  • parthenogenetic reproduction; continuous moulting; cladocerans reach maturity in 3-8 moults (Ref: Wiki)
