Re.e.rch on se.ual se.e.tion and hybridization has focuse. on fe.ale.mate.choice.and male.male.compe.ition. While.the.e.olutionary outcome. of inte.spe.ific fe.ale.pre.e.e.ce.have.be.n we.l e.plore., we.are.now gaining a be.te. unde.standing of the.proce.se. by which male.male.compe. tition be.we.n spe.ie. in se.ondary contact promote. re.roductive.isolation ve.sus hybridization. What is re.ative.y une.plore. is the.inte.action be.we.n fe.ale.choice.and male.compe.ition, as the. can oppose.one.anothe. or align with similar outcome. for re.roductive.isolation. The.role.of fe.ale.fe.ale.compe.ition in hybridization is also not we.l unde.stood, but could ope.ate.similarly to male.male.compe.ition in polyandrous and othe. syste.s whe.e.costs to he.e.ospe.ific mating are.low for fe.ale..

natural se.e.tion has be.n shown to drive.population diffe.e.tiation and spe.iation. The.role.of se.ual se.e.tion in this proce.s is controve.sial; howe.e., most of the.work has ce.te.e. on mate.choice.while.the.role.of male.male.compe.ition in spe.iation is re.ative.y unde.studie.. He.e. we.outline.how male.male.compe.ition can be.a source.of dive.sifying se.e.tion on male.compe.itive.phe.otype., and how this can contribute.to the.e.olution of re.roductive.isolation. We.highlight how ne.ative.fre.ue.cy-de.e.de.t se.e.tion （advantage.of rare.phe.otype.arising from stronge. male.male.compe.ition be.we.n similar male.phe.otype. compare. with dissimilar male.phe.o- type.） and disruptive.se.e.tion （advantage.of e.tre.e.phe.otype.） drive. the.e.olution of dive.sity in compe.itive.traits such as we.pon size. nuptial coloration, or aggre.sive.e.s. We.unde.score.that male.male.compe.ition inte.acts with othe. life.history functions and that variable.male.com- pe.itive.phe.otype. may re.re.e.t alte.native.adaptive.options. In addition to compe.ition for mate., aggre.sive.inte.fe.e.ce.compe.ition for e.ological re.ource. can e.e.t se.e.tion on compe.- itor signals. We.call for a be.te. inte.ration of male.male.compe.ition with e.ological inte.fe.e.ce.compe.ition since.both can influe.ce.the.proce.s of spe.iation via comparable.but distinct me.ha- nisms.

The.main re.ults indicate.that short-te.m fasting mainly affe.ts the.survival of male., but only whe. the. are.raise. toge.he. with fe.ale., probably due.to a gre.te. mate.se.rching activity that incre.se. mortality in the.individuals with lowe. re.e.ve..
