Rap1 recruits Sir4 on acetylated histones, then recruits both its binding partner Sir3 and the HDAC Sir2. 
Sir3 and Sir4 then interact directly with histones H3 and H4. Once Sir3 and Sir4 have bound to histones H3 and H4, 
Sir2 deacetylates histones
Sir2-dependent deacetylation represses transcription.

The fundamental niche of a species is the range of abiotic conditions under which species can persist. 
This includes the range of temperature, humidity, and salinity conditions that allow a population to survive, grow, and reproduce.
