Hello, Manci.
I am a Brazilian master student in Aveiro University, Portugal.I wonder if you would authorize me to use your images of Ziziphus lotus (L.) Lam. So that I use them to illustrate, with watercolor, my master’s work.
I would like to add that the University’s Department of Biology admits the possibility that my work will be published.
Therefore, if you authorize the use of the image, you will also have to admit that possibility. In any case, I would give you enough credits for the availability of the photographic image.
