Young polar bears are often the most vulnerable to detrimental effects of pollutants. To learn more about levels of mercury in polar bear cubs and their mothers, scientists measured total […]
Big Fish Eats Little Fish: Biomagnification of Natural Toxins
Naturally occurring poisons produced by some microorganisms can concentrate to dangerous levels in carnivorous fish, just like man-made pollutants do. In this study, researchers travelled to the Republic of Kiribati to investigate how ciguatoxins, responsible for ciguatera fish poisoning, are transferred between species in a complex reef ecosystem.
