Big animals’ extinction forever alters environment, study shows

… them,according to a joint report by UC Berkeley, Stanford University, California State University Sacramento and the University of Chile. “Ecological studies have shown that if you pull out a top predator or a key herbivore today, you get dramatic change in the ecosystem,” said Anthony Barnosky, a UC Berkeley professor of integrative biology and the study leader. “Our study makes it clear that in the past, such changes have lasted for thousands of years. These extinctions really do …

What the animal world would look like if humans never existed

… during the last Ice Age was mostly due to the spread of humans rather than climate change. “Last year we published another study, which along other studies, clearly suggested that humans were a massive driver in the large extinction which occurred near the end of the last ice age,” lead study author and postdoctoral fellow in bioscience Soren Faurby told Foxnews.com. “During this work we started talking about just how big the effects of humans was and how the world would have been …

Cushion plants harbour tiny mountain worlds inside

… domes too. Within each cushion plant’s structure is a totally different world – a sheltered microcosm with moderate temperatures, higher moisture and good soil. “They form a shape that can be compared to a turtle,” says Fabien Anthelme of the French Institute for Development Research based in La Paz, Bolivia, who studies alpine plants. “It allows them to develop their own microenvironment, which is moist, warm and rich in nutrients.” Working in the Altai …
