I believe it's a pretty highly contested subject, though, especially considering that it depends heavily on how we measure biodiversity in the first place.<br /><br />Plants, on the other hand, are well known for blatantly ignoring most of the patterns and standards that we find in other organisms, so I wouldn't be at all surprised if what applies to animals doesn't apply to plants (though, on that note, how does one best define 'smaller size' in an organism without determinate growth?)Christopher Taylorhttps://www.blogger.com/profile/11075565866351612441noreply@blogger.comtag:blogger.com,1999:blog-5460788270738656369.post-48282350019740172882017-02-25T06:00:35.326+11:002017-02-25T06:00:35.326+11:00I also was intrigued by the idea of more diversity...I also was intrigued by the idea of more diversity with smaller size. I think it does not apply to plants, at least I don't see that pattern ... ??
