BIO202H5 Lecture Notes - Lecture 54: Corpus Allatum, Pineal Gland, Pituitary Gland
Document Summary
Sensitive to seasonal changes in photoperiod and temperature. Timing of season reproduction has an effect on reproductive success (fitness) of an anima. Outlines of light from the environment is processed by the body. Input and integration of light: eyes and brain: hormonal integration: brain, corpora allata, prothoracic glands. Input and integration of light: deep brain and retina: hormonal integration: pineal, hypothalamus, pituitary. This year was an early year for the return of the red-winged blackbirds to our campus (first record was the week before reading week). I believe that this occurred because we had a sudden warm period during the winter which likely triggered the return of the red-winged blackbirds. However, because this warm period was quickly replaced by colder weather, it was not good for them to return so quickly, since the weather got cold after reading week ended.
