Abstract Plant competition for soil resources is common in
semiarid rangelands. Plants have various, alternative mechanisms to
deal with soil resource acquisition. They include (1) length, weight
and proliferation of roots, (2) root length density, and (3) root colonization
by arbuscular mycorrhiza. In rangelands of Argentina, plants
are exposed to herbivory after natural fires. As a result, knowledge
on how these disturbances impact root traits is important for outlining
guidelines focused on rangeland management and improvement.
Our aim was to analyze the effects of defoliation after a controlled
burning on root traits (1) to (3) on… More >
