    Hi Giles,

    I read the abstract. However, in personal observations, I have seen large amount of daphnia trapped by the Utricularia. Naturally, this paper was no doubt well researched, but I do think that daphnia and similar organisms do play a large roll in the plants diet in most circumstances. Here in the "natural" artificial conditions of the water surrounding my bog and in the pond in my backyard, I have often observed traps containing upwards from 3 or 4 daphnia in them.

    Though I could see the plants benefiting from algal growth inside the traps, this seems to me as more of a side effect beneficial in years of food shortage, rather than a primary food source.

    Don't know if this really helps any, but I thought I'd add it.

    I could only see two pics (?) but they were beautiful and fascinating. Nice job, as always, Noah. [img]http://www.**********.com/iB_html312/non-cgi/emoticons/smile.gif[/img]

    Interesting discussion too.

    I had deleted some of the pictures from my account since this discussion started in August due to space limitations, but I uploaded them again for you or others who may have missed the original posting/discussion.

    As to my last comment, here is a picture of plants in my backyard, traps filled with daphnia which naturally thrive in the water that the utrics grow in.

    -that algae would be a more important food source than daphnia seems odd to me, considering the considerable amount of daphnia trapped by the plants. However, these conditions, it must be observed, are in my backyard, not in the wild, where daphnia sources could be considerably lower.

    There is a way to find out, if anyone wants a thesis. I read an abstract recently about research which used carbon isotope testing to support the hypothesis that ampullaria get much of their nutrition from leaf detritus.

    Great photos! What elevation was this lake at?
