Soil food webs grow more varied in farmland and tropics, global analysis reveals

Phys · · 579 words · By University

An international research team led by the University of Göttingen analyzed over 17,000 soil samples to study trophic diversity in soil animal communities. The study found that feeding diversity is higher in agricultural ecosystems and tropical regions compared to woodlands and temperate regions, suggesting that environmental stressors may force animals to broaden their diets.
