A line on a diagram or map connecting points of equal gradient or inclination.
- ‘When resources synergistically improve performance, combinations yielding equal benefits are represented by an isocline that is convex to the origin.’
- ‘The isocline and full system analyses show similar patterns when there is variation in performance.’
- ‘Because this would change the slope of the isocline, it could be an important mechanism promoting coexistence when habitat selection is constrained.’
- ‘The null isoclines give the threshold of zero growth for each of the two species, and their intersection specifies the equilibrium point.’
- ‘For example, one might assess whether the distance along a river or a topographic isocline is more biologically relevant than distance ‘as the crow flies.’’
Late 19th century (denoting an isoclinal line or fold): from Greek isoklinēs equally balanced from klinein to lean, slope.
