On planet Earth, most organisms draw their life-fuel from the Sun. Our plant life uses photosynthesis to convert the Sun’s rays into food, and our animal life forms consume these plants either directly or indirectly. The fact that the Sun is absolutely essential to life on Earth has led many scientists to conclude that a […]
Single celled prokaryotic microbes, such as bacteria and archaea, control almost every aspect of our daily lives, from our individual health to the elemental cycles that maintain the global biosphere. A major challenge for microbial ecologists is cataloging the vast diversity of prokaryotic life on Earth and connecting this diversity with specific functions, such as […]
It was no ordinary fishing trip. In May 2011, Denis Tweddle, an honorary research associate of the South African Institute for Aquatic Biodiversity (SAIAB), led an expedition to collect little-known fishes from the remote rivers of southern Malawi. As an International Barcode of Life postdoctoral fellow at SAIAB, I joined the expedition to collect genetic […]
