Summary:
Researchers in Mexico say the mighty Mayan civilization that thrived in central America for 2700 years from 1800 BC, might have been brought down by climate change. Based on research deep underground, the scientists say there's evidence of long-term drought during the period of population decline.

The Rewilding of California Wolf Territory

The Rewilding of California Wolf Territory

FORA.tv (Dec. 18, 2014) — The Rewilding of California Wolf Territory California Academy of Sciences - California Academy of Sciences What would it be like to live in a world with no predators roaming our landscapes? Would their elimination bring about a pastoral, peaceful human civilization? Or in fact is their existence critical to our own, and do we need to be doing more to assure their health and the health of the landscapes they need to thrive? In this talk, Cristina Eisenberg delivers a compelling call for the necessity of top predators in large, undisturbed landscapes, and shows us how a continental-long corridor-a "carnivore way"-provides the room they need to roam and disperse. Along the way we will follow in the footsteps of six large carnivores-wolves, grizzly bears, lynx, jaguars, wolverines, and cougars-on a 7,500-mile wildlife corridor from Alaska to Mexico along the Rocky Mountains. Backed by robust science, Eisenberg shows how their well-being is a critical factor in sustaining healthy landscapes and how it is possible for humans and large carnivores to coexist peacefully and even to thrive. University students in natural resource science programs, resource managers, conservation organizations, and anyone curious about carnivore ecology and management in a changing world will find a thoughtful guide to large carnivore conservation that dispels long-held myths about their ecology and contributions to healthy, resilient landscapes.
