Study Maps What Mammal World Would Be Like Without Humans 

By James Eng | August 24, 2015 If it weren’t for the presence of humans, elephants and rhinos would likely be roaming across Europe today, and North and South America would also be flush with a variety big mammals. That’s the conclusion of a study that projects what a world map of mammals would look like if Homo sapiens had never existed. The researchers say that much of the world would resemble the Serengeti of Africa, virtually the last place on Earth that’s home to a high …

The role of species competition in biodiversity

… diversification dynamics as increases in size predispose the development of hypercarnivory behaviors and selective feeding. These adaptive constraints place canids in danger of extinction by restricting their possible sources of food. Via a Bayesian analytic framework, the researchers have determined that the two extinct subfamilies that form the basis of their study were ultimately wiped out by the competitive effects of other carnivore clades, previously considered a rare occurrence, but …
