Extinction of a species is not just a permanent loss of biological diversity, but may have ripple effects as co-dependent species suffer from the absence of what may be linked predator-prey relationships.    Astrobiology Magazine -- The global extinction crisis ignores thousands of affiliated species that are also at risk of being wiped out, making the list of endangered species much larger and more serious than originally thought, says a study produced in part at the University of Alberta...
