Almirón M. G., Martínez Carretero E. E., Navas Kaluza M. D., Rothis L. M., Linking hydrological, geomorphological and biological properties in hyper-arid conditions: Distribution processes of a dominant clonal cactus by run-off, Austral Ecology, 2019, 44(2):209-215, doi: 10.1111/aec.12665
A field experiment on the transport of Tephrocactus aoracanthus segments by water runoff after downpours. It tracked 30 marked segments in a channel and 30 beyond its reach, taking microrelief and interception by shrubs into account. The paper describes transport over hundreds of metres and changes in position after successive rains.
