Experimental evidence of early costs of reproduction in conspecific viviparous and oviparous lizards.

abstract：:Recent work [Ecoscience (2000) vol. 7, 395-397] suggests that the burying beetle Nicrophorus pustulatus may have undergone a remarkable host shift, exploiting snake eggs rather than carrion as resources for breeding. We conducted behavioural and physiological experiments to examine the hypothesis of a host shift and t...

However, some groups such as lizards appear constrained in the evolution of morphological specializations associated with specialized diets.
