Interactive effects between plant functional types and soil factors on tundra species diversity and community composition
Abstract Plant communities are coupled with abiotic factors, as species diversity and community composition both respond to and influence climate and soil characteristics. Interactions between vegetation and abiotic factors depend on plant functional types (PFT) as different growth forms will have d...

Abstract Plant communities are coupled with abiotic factors, as species diversity and community composition both respond to and influence climate and soil characteristics.
