Interaction between species is greater towards the tropics, lowlands

Researchers from the University of British Columbia conducted one of the largest field experiments to investigate the Darwinian theory that species located in the tropics and lower elevations interact more with other species than anywhere else in the world. And, as stated in Science Advances, the team ultimately proved the theory true. "Theory predicts that interactions among species — like predation and competition — will be strongest in the warm, productive, biodiverse ecosystems of the tropics and at low elevations," said lead author Anna Hargreaves, formerly …
