    Or just set up a security cam to film a lowii that you grow outdoors (you'd have to live in the right climate). Set it on a motion sensor (that would have to be one sensative sensor&#33[img]http://www.**********.com/iB_html/non-cgi/emoticons/wink.gif[/img] and see who visits the pitchers.
    Ok, so that's not very practical....

    Well Troy, yes it would prove that!, but remember if Lowii is evolving to just catch poo and nothing else, then it is putting itself at risk of being extinct. In nature this could happen in very isolated areas. Thus, you may never find this to be the case. Anything that give any hints that Lowii prefers poo than regular insects would prove Charles Clarke right!!.

    I could also argue that the reason why Lowii catches a lot of poo is because its pitchers are very wide at the top. So it is a matter of increasing lowii's chances. the same should apply to N. ephippiata.

    Another point to consider is that this plant is found in more than one area: Trus madi, kinabalu and i forgot the third one. I am sure birds go through all these areas and fly over the same areas where other types of nepenthes are. If Lowii is developing a selective advantage over the other types of Neps, It may have become a predominant population in the wild.

    My theory is that they N. Lowii evolved to feed on insects and feces. If it strictly was designed for eating...poo...then it would make the 'honey' ever more irresitable to birds...and not just insects...anyways..this plant is awsome...

    Augustin,

    you have to prove this first! And only then the rest of your logic might be valid. I have to agree with Troy that a field study would yield scientific valuable results.

    Hi all:

    Yes Joachim, everything mentioned here is still a hypothesis. But I am not convinced that by finding poo in Lowii's pitcher means that this is its preferred food. Perhaps it is the most common, but it may not be the ideal diet.

    It happens to humans too!. If you go to a different country and you start consuming the local food, does not mean it is your preferred food, just the more abundant under certain circumstances. I wonder if these places are deprived of birds, could Lowii still survive or die without poo??.

    Augustin,

    To talk about 'preferred food', as if N. lowii can make some sort of conscious decision about what it does or doesn't like to eat is anthropomorphism at its worst. CPs have evolved strategies which enable them to advantageously compete for niche space by supplementing their nutrient intake by the means capturing prey. They don't choose their food or express any preferences, but they can evolve means (trap shape, colour, attractants etc) which tend to attract a particular type of prey over others.

    The fact is that large quantities of bird poo has been found in the pitchers of this species and it seems reasonable to me that the plants may have evolved the strategy of attracting birds for this purpose. Until someone does the laborious long-term field studies, in a remote and hostile environment (at great cost too! ), it remains a hypothesis, quite a good one too, in my opinion. If you don't like it, get a botany degree and some post-graduate experience in plant ecology, find some funding and trek off to Borneo for a few months hard work. Then when you have disproved the hypothesis, publish it and convince others of your findings. There is nothing wrong with the hypothesis, its just a reasonable idea, waiting to be investigated.

    Let's relate to the Venus flytrap, you think it was specifically evolved to catch just flys? Nope whatever it can get it's green little nippers on it takes.

    Evaluation on a pitcher plant whatever falls in it takes advantage of. You must also remember if the plants in cultivation were/are evolving to catch bird feces then they would begin dieing off in thousands of collections world wide and I know quite few people who have mature lowii and they have no contact with feathered friends whatsoever, just bugs and maybe mild fertilzer.
