    When is a land plant not a land plant?

    When it’s an eelgrass. OK, this needs some explanation. A popular notion is that the kingdom Plantae is essentially synonymous with the term land plants. And that is understandable; after all, this group of organisms is arguably all about the conquest of the land and adaptations to a terrestrial existence by entities that had previously […] More

    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

    Modelling seagrass growth and development

    Transplanting seagrasses can help restore ecologically important and threatened marine ecosystems. Based on the L-system formalism, Renton et al. present a functional–structural plant model of seagrass growth that integrates data collected from short-term trials and experiments for Posidonia australis. They use the model to conduct an evaluation of different transplanting strategies and find that reasonable long-term […] More
