While BoT, Utter Dark, Astral Corruption and like should automatically void NAP, I do not see other spells end NAP unless specified clearly in NAP agreement. BoT and alike all directly damage other players (friendly or not). So it is considered offensive spell casted to your land. I do not see Arcane Nexus and especially FoA automatically end NAP. But you can always say that when you sign NAPs.
