    I should note that traditionally, Laminaria has been placed in the Phaeophyceae, but some taxonomists now recognize the Laminariaceae as its own family.

    In other aquatic news, I just received the following press release: Study Shows Ocean “Deserts” are Expanding.
    (someone seems to have signed me up for US NOAA press releases, because I don’t remember doing so)

    Sorry, but I have to say this…”Well, DUH!” About removing a holdfast facing the incoming waves versus facing the shore.
    We are avid DYIers, and have done a lot of construction. You can notch or make a hole in a beam or joist at the topside without compromising the structural integrity. Notching on the bottom side, the side that is being stretched the most as the weight pushes down from above, is a big no-no and compromises the ability of the beam or joist to take the weight.
    And I am sure there are many other examples. Cutting the side under the most tension is always a good way to destroy the structure.

    What is the second picture?

    Katherine – Of course it is intuitive that the holdfast should be reinforced on the wavefacing side but without an actual experiment this will only ever remain an intuition. Furthermore the fact that the organism can direct it’s development so as to compensate for this force is quite an amazing discovery and provides further avenues of research.

    I enjoyed this article very much. The idea of growth rings in kelp makes me want to go out into my Texas woods and find other things (besides trees) that might have growth rings. lol! Fascinating and insightful. Loved learning that kelp can withstand such strong forces. Amazing.

    I realize this comment comes a year late, but I believe the second picture illustrates the annual rings discussed in the text.
