Many large mammals have lost genetic diversity, often thanks to the actions of people shrinking their populations. The implications can be severe because without genetic diversity, a population does not have a “genetic database” to fall back on to adapt to environmental change. The Iberian lynx (Lynx pardinus) is no stranger to this reduction in diversity. Human…

Dying coral reefs, rainforests transforming into savannas, grasslands turning into deserts – these are ecosystem “tipping points”, boundary lines we’re desperate not to cross.
