Letkbe a field of characteristicq,a smooth geometrically connected curve defined overkwith function field. LetA/Kbe a non-constant abelian variety defined overKof dimensiond. We assume thatq= 0 or > 2d+ 1. Letp≠qbe a prime number anda finite geometrically Galoisand étale cover defined overkwith function field. Let (τ′,B′) be theK′/k-trace ofA/K. We give an upper bound for the-corank of the Selmergroup Selp(A×KK′), defined in terms of thep-descent map. As a consequence, we get an upper bound for the-rank of the Lang–NérongroupA(K′)/τ′B′(k). In the case of a geometric tower of curves whose Galoisgroup is isomorphic to, we give sufficient conditions for the Lang–Nérongroup ofAto be uniformly bounded along the tower.
