The analogy between the arithmetic of varieties over number fields and thearithmetic of varieties over function fields is a leading theme in arithmeticgeometry. This analogy is very powerful but there are some gaps. In this notewe will show how the presence of isotrivial varieties over function fields (theanalogous of which do not seems to exist over number fields) breaks thisanalogy. Some counterexamples to a statement similar to Northcott Theorem areproposed. In positive characteristic, some explicit counterexamples tostatements similar to Lang and Vojta conjectures are given.
