Tropical Deciduous Forest  Temperatures are hot year-round, averaging 25–39ºC. Rainfall is substantial, at around 130–280 cm per year, but the dry season is distinct, often 2–3 months or longer. 

Closer to the Tropics of Cancer and Capricorn Much of India consists of tropical deciduous forest, containing teak trees. Because of the distinct dry season, many of the trees in tropical deciduous forests shed their leaves.

Feedback mechanisms suppress signaling by the PKA pathway:

1. Intrinsic GTPase activity of Gαs

2. PDE acts to hydrolyze cAMP to 5′-AMP

3. By BARK
