The quantitative ecology section needs revising. Either parametric statistics should be avoided OR data are transformed to conform to the assumptions of a parametric test. I think more references are needed to justify the points being made and to guide readers to places where they can look up advice on how best to analyse parasitic data.Emble64 (talk) 12:26, 30 September 2011 (UTC)
the section headed value is dubious. It inherently assumes that diversity somehow has an absolute intrinsic 'value'; of course this is entirely a human and subjective imposition of value-statements. The best that can be said is that parasites may have 'effects' at the large population and ecosystem levels, and to note what predictions have been made. However, even this is slightly spurious, since these are entirely hypothetical 'benefits', as far as I am aware the speculations being made in this section have never been substantiated. Use of words like "noble" in the description are also loaded with absolute value-judgements which are incompatible with biological science. I suggest this short section be reworked or removed.
Are parasites genuinely unable to be from the same species as their host(s) (which is what this article states)? What about parasitic twins? Heck, what about embryos and early fetuses? Futurist110 (talk) 01:15, 7 July 2013 (UTC)
Most parasites are specialized, infecting species with a certain physiology. I tend to think, however, that the generalisation is undue. If you could please quote the sentence that stated that it would be nice.
As for parasitic twins - irrelevant since this is not actually part of a lifecycle, and the so-called "parasitic twin" is not actually developed.
As for fetuses etc.: Don't stop there - let's talk about children in general! François Robere (talk) 15:16, 8 July 2013 (UTC)
I've edited the section titled "host defense." I've added more material, but still kept the content to a minimal since most of the detailed mechanism of host/parasite interactions are located on other wiki pages. Let me know what you all think.
