Life is made up of fights, battles, wars, etc. The best doesn't always win, but the victories that come from personal and professional struggles have a greater academic connotation. I was fortunate enough to receive guidance for both my undergraduate and master's degrees from two excellent professionals from the Emilio Goeldi Museums of Pará. Today, as a university professor, I have an idea of the importance of making the right choice in what you want to achieve. To all those who contributed directly and indirectly to this research, my thanks.
