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.

3D Laser Mapping 'Weighs' Trees

3D Laser Mapping 'Weighs' Trees

Reuters - Innovations Video Online (Jan. 14, 2015) A laser scanning technique is being developed by scientists to 3D map the structure of trees in order to determine the biomass and carbon stocks in forests more accurately than by other methods. The authors of the study hope their research will provide better understanding of the role of forests in reducing man-made CO2 emissions and give an effective framework for climate policymakers.

Coral Reef Competitive Advantage Through Mimicry

Coral Reef Competitive Advantage Through Mimicry

FORA.tv (Jan. 30, 2012) Join us to welcome new curator on the ichthyology team, Dr. Luiz Rocha. Dr. Rocha's research interests center on the evolution, biogeography, and ecology of coral reef fishes. His overarching goal is to understand what drives the extremely high biodiversity found in tropical reefs. He has embarked on numerous expeditions around the world, including the Philippines, Indonesia, Australia, Polynesia, Micronesia, the Caribbean, South America, and Africa. His field work in Sao Tome was covered by National Geographic in 2008, and he appeared in a Science Channel documentary in 2009 discussing the effects of radiation at Bikini Atoll.
