A timelapse of the leaves of O. triangularis closing at night. The recording is at ~750x actual speed and covers a 1.5 hr period of time. The leaves of O. triangularis move in response to light levels, opening in high ambient light (in the day) and closing at low light levels (at night). During this movement, the leaflets fold at the level of ...

At lowered light levels the leaves fold down; timelapse recorded at ~750x actual speed and covering a 1.5 hr period of time. In biology , nastic movements are non-directional responses to stimuli (e.g. temperature , humidity , light irradiance ) that occur more rapidly than tropisms and are usually associated with plants .
Note this darkening is "fake", it is approximately 1/4 the actual lowering in light levels over this time period. - Zephyris Talk 23:52, 16 June 2010 (UTC) Support This is one of the few good videos Hive001 contact 08:14, 13 June 2010 (UTC) Weak support. This video doesn't blow me away, but it's got fairly high EV and is of acceptable quality.
