Introduction
I am a biologist, interested in understanding how nature works, passionate about discovering natural landscapes and their living organisms across my country, Algeria. I am mainly studying how populations react to global change and how this affects their long-term viability. Ongoing research includes a project on aquatic ecology with respect to the study of aquatic macroinvertebrates in Algeria. (2) assess mechanisms responsible for changes in biodiversity (3) assess the role of macroinvertebrate
