Lead ammunition used by hunters has us all in its sights

Written by

Dr Arnemo has teamed up with scientists worldwide to draw attention to the fact that hunting and lead ammunition remains a significant source of lead exposure in humans and wildlife.

For millions of people, game meat is their primary source of protein, but if the animal is shot using lead (Pb) ammunition, its meat can be toxic. The lead in the ammunition also finds its way into wildlife, ecosystems, and the global food chain, taking the poison far beyond the gun barrel. There are non-lead alternatives, but hunters are slow […]

Scalloped hammerhead sharks have more complex migratory routes than expected

Written by

By assessing their migratory routes, the researchers ensure that populations of the scalloped hammerhead shark are protected through conservation and management tools.

Using a new method to study migratory routes of scalloped hammerhead sharks, Dr Claire Coiraton and Dr Felipe Amezcua, based at the National Autonomous University of Mexico, identified a more complex picture than previously thought. It turns out that not all sharks follow the same pattern of movements, with some preferring to stay in coastal areas while others opt for […]
