You have found the Ulanowicz et al. paper inconsistent, misleading and terminologi-cally incorrect. This is very bad, I agree.
Flow processes in soils are closely related to groundwater quality often affected by human activities. Because hydrological models usually lack explanatory power, direct visualization of flow paths in dye tracer infiltration studies has become a standard tool in soil hydrology. These experiments provide images of dye-stained paths in soils and help… (More)
