Soil Mesofauna Responses to Fire Severity in a Sclerophyllous Forest in Central Chile

Forest fires may have severe impacts on the aboveground biodiversity and soil chemical and biological properties. Edaphic organisms are highly sensitive to disturbances and are typically used to measure the magnitude of these events. Overall, little is known about the responses of these organisms to...
