Dr. Ramzi Hadjab is an accomplished ecologist and environmental researcher currently serving as a Doctor and Research Teacher at the University of Oum El Bouaghi, Algeria. With a Ph.D. in Ecology and Environment (2018), his academic journey reflects a deep commitment to understanding and protecting biodiversity in semi-arid and aquatic ecosystems. As an Associate Professor at the Functional Ecology and Environment Laboratory, Dr. Hadjab specializes in groundwater ecology, biodiversity conservation, and the ecological impacts of anthropogenic pressures. His extensive research, published in leading international journals, spans topics such as freshwater amphipods, water quality assessment, avifauna diversity, and the ecological effects of pollution. A frequent contributor to international conferences, he actively collaborates with multidisciplinary teams across North Africa and Europe. Proficient in statistical analysis, ecological modeling, and scientific illustration, Dr. Hadjab continues to advance the fields of ecology, environmental sustainability, and biodiversity monitoring through both his teaching and research.

C. Shiva Shankar is a dedicated Senior Research Fellow at the Zoological Survey of India, specializing in taxonomy, molecular systematics, and ecology of aquatic beetles, fishes, and freshwater crabs. He has significantly contributed to biodiversity documentation through the discovery of new species and first records in India. His doctoral research on aquatic beetles of the Eastern Ghats has generated more than 500 DNA barcodes, marking the first molecular systematic study of aquatic beetles in the country. He has authored over 15 peer-reviewed publications, book chapters, and a co-authored book on threatened fauna. His expertise spans DNA barcoding, water quality analysis, GIS and GPS field surveys, and museum specimen curation. With extensive fieldwork across Indian ecosystems, he has collected and identified over 95 species of aquatic beetles, including rare and endemic taxa. He has successfully submitted over 600 DNA sequences to NCBI, strengthening global biodiversity databases. Beyond research, he actively participates in national conferences, workshops, and biodiversity initiatives, enhancing collaborative conservation efforts. Recognized for his hard work, leadership skills, and self-motivation, he is committed to advancing aquatic biodiversity science. His career vision is to contribute to global research excellence while promoting sustainable management of freshwater ecosystems.
