My basic interest in submission is to add my voice regarding the direction of research for the genus Drosophila, especially for Puerto Rico, and especially regarding environmental-evolutionary issues. (Incidentally, I find it confusing that you seem to use the word "Drosophila" both for the genus and for the species Drosophila melanogaster).
My and my students' research interest, for most of my career, has been the evolution of reproductive strategies in the cardini group of species, especially the dunni subgroup, and I believe that the environmental-evolutionary aspects of Drosophila research, of necessity concerned with species other than Drosophila melanogaster as well as the latter, is a critical subject during this period in human history, where in the US as well as quite a few other countries, the strongest political forces appear to scorn any interest in biodiversity and climate change.
