    Seagrasses cheat on sex!

    Survival at geographic range edges, where organisms are often at the limits of their physiological tolerances, can trigger unusual responses in reproduction. Sinclair et al. describe the first observations of pseudoviviparous shoots in the marine angiosperm, Posidonia australis. Unfertilized flowers cheated and ‘switched’ to plantlet development. Multilocus genotypes showed these plantlets were genetically identical to […] More
