A classic example of reproductive character displacement, presumed to be caused by reinforcing selection, is flower-color variation in the native Texas wildflower Phlox drummondii. By contrast, “reproductive character displace- ment” refers to trait evolution stemming from selection to lessen sexual interactions between species and, accordingly, acts on traits associated with reproduction (e.g., sexual signals or female mate preferences) (Brown and Wilson 1956; Crozier 1974). 0000045940 00000 n @W:9)_ho>$N.-g#EH`jThUYZOiko/1\0J] This hypothesis predicts divergences restricted to regions of sympatry in partially overlapping species, but such “reproductive character displacement” has rarely been confirmed. +3jNS.uT)Wn+F!K=oSI\\g6%[1'k&K/(CnKSs(Djc[QId+90sW5,Wg-Vs:rBYkS_--fhj=a\tR1qT[U&@3;/`FuE(5NA`\ng\n/TFRYPKW9po=V;bcr eh.C?2. ,FhE3mh*mSep)HTQdcn@O4QE^?#1`IWO"1:dX=&;[JG6_WbbJHpo_'*keY2K@-shG *#HcDTJpHR SijR^.bHgckX*$fLecQ,!971GA*6BH5mbp&pjH/"I49D1Hf"">SrKohDCnRVM8nGe lSh<1IMLGC53rM2#?_!+=j+)]MK/0ca.R:HQ8Z=)e-7`6\*s[&,a(fdrrpAiZj_]^jZ8 KU2a`OrDg&6Q7,Lh2u!r)b)nS@pVY7*OhY\q(4.
