Experimental test of predation's effect on divergent selection during character displacement in sticklebacks.
Ecological character displacement is common in nature but the mechanisms causing divergence are not well understood. The contributions of ecological interactions other than competition have received little attention. We conducted a pond experiment to explore the contribution of both competition and predation to character divergence in threespine stickleback species. We estimated the strength of...
متن کاملDeclining interspecific competition during character displacement: Summoning the ghost of competition past
Prevailing theories of biotic diversification incorporate resource competition as a leading cause of divergence between new species. In support of this, many cases of divergent character displacement between close relatives (congeners) are known. Yet, experimental tests of underlying mechanisms are uncommon. In a pond experiment with threespine sticklebacks (Gasterosteus spp.), we tested the pr...
متن کاملFrequency dependent natural selection during character displacement in sticklebacks.
We know little about how natural selection on a species is altered when a closely related species consuming similar resources appears in its environment. In a pond experiment with threespine sticklebacks I tested the prediction that divergent natural selection between competitors is frequency-dependent, changing with the distribution of phenotypes in the environment. Differential growth and sur...
متن کاملEcological character displacement and speciation in sticklebacks.
We present evidence of ecological character displacement among species of threespined sticklebacks that inhabit small lakes of coastal British Columbia. Geological data suggest that the populations resulted from multiple divergence and speciation events over the past 13,000 yr. In lakes with two species, one is invariably "limnetic" in morphology and habitat, and the other is "benthic." Other l...
متن کاملReproductive character displacement of male stickleback mate preference: reinforcement or direct selection?
Reproductive isolation can evolve between species as a byproduct of adaptation to different niches, through reinforcement, and by direct selection on mating preferences. We investigated the potential role of direct selection in the reproductive isolation between sympatric species of threespine sticklebacks. Each sympatric pair consists of a small-bodied limnetic species and large-bodied benthic...
