Photoperiod In Gammarus Setosus
The abiotic factor that we plan to investigate and study is the light intensity. The length of the photoperiod in a Gammarus setosus’s habitat is linked to them being able to successfully grow and reproduce (Steele & Steele, 1970). The Gammarus setosus contain modified cilia, which are the primary sensory receptors in several photoreceptors (Steele, 1986). There have also been studies that show that the reproductive cycle of a female Gammarus setosus can be faster or slowed down by the photoperiod (Steele, Steele, & MacPherson, 1977). Furthermore, there is also evidence that photoperiod has an influence on the timing of the reproductive cycle (Steele et al., 1977). The less exposure to a specific amount of photoperiod (light) leads to an increase
in development (Steele et al., 1977). Exposure to a lengthened amount of photoperiod (light) leads to inhibition (Steele et al., 1977). The scientific research question of our study is do different types and amounts of light intensities have an affect on the Gammarus setosus’s movement? My prediction is that the Gammarus setosus will produce more movement when there is less amount of light intensity.
