In the "Modern Context section of Effects of climate change on plant biodiversity, there are no citations. I am not sure if the author wrote the section from their own knowledge, or if that counts as a form of plagiarism. In the Change in distributions section, there are too old sources that are used to support the sentence about plant ranges shifting, but I think there must be more current examples of range shift. I also noticed in the Talk that comments, and I am assuming changes, have not been occurring on a regular basis. I think that maybe the effects of climate change on plants may not be a popular topic for Wikipedia readers?
