Resilience |
Ability of the ecosystem to absorb a change in oxygen
diffusivity without tipping to the alternative ecosystem
state. |
Resilience of the oxic state |
Ability of the ecosystem to absorb a
decrease in oxygen diffusivity without shifting
from oxic to anoxic. Resilience is therefore higher when
the oxic-anoxic tipping point is at
lower oxygen diffusivity. |
Resilience of the anoxic state |
Ability of the ecosystem to absorb an
increase in oxygen diffusivity without shifting
from anoxic to oxic. Resilience is therefore higher when
the anoxic-oxic tipping point is at
higher oxygen diffusivity. |
Dominant group |
Functional group that dominates a given ecosystem state
(oxic state: cyanobacteria; anoxic state: sulfate-reducing bacteria and
phototrophic sulfur bacteria). |
Suppressed group |
Functional group that is inhibited in a given
ecosystem state and therefore has zero or low abundance (oxic state:
sulfate-reducing bacteria and phototrophic sulfur bacteria; anoxic
state: cyanobacteria). |
Collapse trajectory
|
Trajectory with increasingly unfavourable conditions for a given
functional group, leading to its collapse.
(cyanobacteria: trajectory of decreasing oxygen diffusivity;
sulfur bacteria: trajectory of increasing oxygen diffusivity)
|
Recovery trajectory
|
Trajectory with increasingly favourable conditions for a given
functional group, leading to its recovery.
(cyanobacteria: trajectory of increasing oxygen diffusivity;
sulfur bacteria: trajectory of decreasing oxygen diffusivity)
