To grasp our present situation, however, it's necessary to distinguish between naturally recurring planetary disturbances and the planetary responses to human intervention.
Combined with enhanced food availability because of cycles of resuspension and deposition caused by recurring hydrodynamic disturbance, these factors may explain the tighter positive relation between nematode structural diversity and trophic conditions in sediments at the Gollum stations compared to the Whittard Canyon.
