Environmental gradients often lead to the parallel evolution of populations and species. To what extent do such gradients also lead to parallel evolution of the sexes? We used guppies (Poecilia reticulata) to examine the parallel and independent (sex-specific) aspects of population divergence in response to predation and habitat features. Geometric(More)
We report on a search for the trilepton decay signature from the associated production of supersymmetric gaugino pairs, ˜ x 6 1 ˜ x 0 2 , within the context of minimal supersymmetric models that conserve R parity. This search uses 95 pb 21 of p ¯ p data taken at p s ෇ 1.8 TeV with the D0 detector. No evidence of a trilepton signature has been found, and a(More)
