Hi, Xuguorui:<br /><br />I have uploaded your edited document, and I hope that you find the suggestions helpful. If you have any questions, please send a message to me via Editor World.<br /><br />A fascinating&nbsp;and valuable&nbsp;study! I carefully reviewed your document and I'm confident there&nbsp;are no typos.&nbsp;Although I was careful not to change the content of your paper, please review it carefully, and run spell-check using your dictionary language. I found three instances of S. Alternaflora&nbsp;which I changed&nbsp;to S. Alterniflora. If I was mistaken, please correct.<br /><br />It is probably best to read the comments in the&nbsp;margins first, before reviewing&nbsp;the&nbsp;document&nbsp;with no markups.<br /><br />Good luck with your dissertation. It reads&nbsp;very well to this non-expert!<br /><br />Best wishes - George (TypeRighter)<br />I am usually available for editing between 6:00 am and 10:30 pm (EST). If my status is set to 'unavailable', you can still reach me via Editor World.<br /><br />Don't forget:<br /><br />TRACK CHANGES<br />When you open a document containing tracked changes, it appears in the Final Show Mark-up view.
