Leopard Gecko Photoperiod
The photoperiod is the time a Leopard gecko dragon
is exposed to light over a period of 24 hours. The Leopard gecko photoperiod has an effect on growth, but more
importantly, the day night rhythm of these animals.
Leopard Gecko Photoperiod Sensor
Leopard geckos have a so-called pineal gland
in the top of their head. It is also called a "third eye" which
is sensitive to visible light exposure. During the day, when
visible light is at its most, hormones are secreted by this
gland. When this hormone is low (i.e. when the day length is
relative short, and the evenings are relative long) the lizard's brain picks up that its winder. When there is a sudden
change in concentration from low to high (i.e. during spring)
the these hormones stimulate sex glands to secrete sex hormones.
Leopard Gecko Photoperiod In Captivity
To create a "natural" photoperiod in
captivity the natural lights shining into the container or the
gecko lighting should be on for about forteen
hours per day during the summer period. During winter this time
can be reduced to twelve hours per day. Commercially available
timers can be
used to automate the light cycle.
