However, conservation usually focuses on one or few species at a time. This means that it often doesn’t mesh well with biodiversity maintenance, which requires considering the balance of all species in a given habitat. By managing a system based on the needs of … Continue reading Managing biodiversity: Indigenous knowledge, elephants, and the repercussions of intervention

Biodiversity and human health

Over 250 million years ago, cataclysmic volcanic activity wiped out nearly all life on earth. 65 million years ago, a meteor impact in the Yucatán drove the dinosaurs to extinction. In the past 540 million years of earth’s history, paleontologists have identified five mass extinction events in which over 75% of Earth’s species have died during a relatively short period of time [1]. Unfortunately, it … Continue reading Biodiversity and human health

This was an event so remarkable in earth’s timeline that it would set the stage for the evolution of complex organisms, from sponges to the human body we each reside in. These complex life forms eventually … Continue reading Grand Evolutionary Transitions: The eruption of multicellularity

Understanding Life on the Prairie through Ecological Networks

by Jaclyn Long figures by Wei Wu Grasslands are a type of ecosystem that make up over a quarter of the earth’s land. These habitats are often found in between deserts and forests, and are characterized by low levels of rainfall and regular fires. In North America, grasslands are usually called prairies. The rich soil held in place by grass roots makes them particularly useful for … Continue reading Understanding Life on the Prairie through Ecological Networks

Lights. Camera. Action! How the Hawaiian bobtail squid brings a creative vision to its maritime world of small big screens

by Edward Chenfigures by Jovana Andrejevic On a sunny, nondescript Hawaiian day, a Vibrio fischeri bacterium arises the same as on most other nondescript days: homeless. It hurries along on a ride to work. No, not by car. Not onboard a trolley either. Yes! The great, dynamic Pacific Ocean current. Currency-free and open to all, it’s the road to opportunity and fortune for aquatic hard … Continue reading Lights. Camera. Action!
