  We report on several new results using anisotropies of UHECRs. We improve and
extend the work of Ding, Globus and Farrar, who modeled the UHECR dipole
assuming sources follow the dark matter distribution, accounting for
deflections in the Galactic and extragalactic magnetic fields but using a
simplified treatment of interactions during propagation. The work presented
here employs an accurate and self-consistent treatment of the evolution of
composition during propagation, allows for and explores the impact of "bias" in
the relation between UHECR sources and the dark matter distribution, and
investigates the possible generation of arrival-direction-dependent composition
anisotropies. Limits on the source number density consistent with the observed
anisotropies are derived for the case where UHECR sources follow the dark
matter distribution, and compared to a homogeneous source distribution case.
