Human bycatch happens when cameras that are meant to study nature end up taking pictures of people. Usually, this is caused by camera traps. They work by taking pictures when they detect motion. Scientists place them in nature or on drones to get pictures of wildlife. What happens to the p...
What is an ecological niche? Is it common to find two species occupying the same ecological niche in a functioning ecosystem? What happens when two species occupy overlapping niches? What is predator-prey coevolution? What makes an organism invasive when it's moved...

We need to accomplish three goals: stop overfishing; reduce bycatch; and protect marine habitat. Scientists working closely with economists, lawyers and policy experts can achieve tangible results for the oceans. Examples in the Philippines and other countries have demonstrated how to rebuild fish popu...
