  We determine the scalar field evolution of a braneworld localized black hole
with both dark matter and dark energy components, obtained within a dynamical
and continuous embedding formalism by use of Nash's theorem. We further extract
the associated quasinormal modes for both de Sitter-Schwarzschild-Dark matter
and anti-de Sitter-Schwarzschild-Dark matter solutions, for the different
causal structures (one, two or three horizon spacetimes) given by the space of
parameters. By comparison with standard General Relativity solutions, we infer
possible observable astrophysical differences, and remark on modifications to
previous AdS/CFT correspondence scenarios.
