Selective nectar robbing in a gynodioecious plant (Glechoma longituba) enhances female advantage.

abstract：:Viviparity, the bearing of live young, has evolved well over 100 times among squamate reptiles. This reproductive strategy is hypothesized to allow maternal control of the foetus' thermal environment and thereby to increase the fitness of the parents and offspring. Two hypotheses have been posited to explain this phen...
