Individual colour patches as multicomponent signals
Colour patches are complex traits, the components of which may evolve independently through a variety of mechanisms. Although usually treated as simple, two‐dimensional characters and classified asExpand
The role of interspecific interference competition in character displacement and the evolution of competitor recognition
The extent to which interspecific interference competition has contributed to character evolution is one of the most neglected problems in evolutionary biology. When formerly allopatric species comeExpand
Extensive population genetic structure in the giraffe
BackgroundA central question in the evolutionary diversification of large, widespread, mobile mammals is how substantial differentiation can arise, particularly in the absence of topographic orExpand
A possible non-sexual origin of mate preference: are male guppies mimicking fruit?
In most animals, the origins of mating preferences are not clear. The ‘sensory–bias’ hypothesis proposes that biases in female sensory or neural systems are important in triggering sexual selectionExpand
Environmental Change, Phenotypic Plasticity, and Genetic Compensation

When a species encounters novel environmental conditions, some phenotypic characters may develop differently than in the ancestral environment. Most environmental perturbations of development areExpand
INTRASEXUAL COMPETITION ALONE FAVORS A SEXUALLY DIMORPHIC ORNAMENT IN THE RUBYSPOT DAMSELFLY HETAERINA AMERICANA

  • 1 October 1996
I studied the sex‐limited red spots on the wings of male rubyspot damselflies (Hetaerina americana) in relation to territoriality and fitness in the wild. Both observational and experimental (wingExpand
RAIN FOREST CANOPY COVER, RESOURCE AVAILABILITY, AND LIFE HISTORY EVOLUTION IN GUPPIES
Life history traits in guppies (Poecilia reticulata) vary geographically along a predator assemblage gradient, and field experiments have indicated that the association may be causal; guppiesExpand
SEXUAL SELECTION AND SURVIVAL SELECTION ON WING COLORATION AND BODY SIZE IN THE RUBYSPOT DAMSELFLY HETAERINA AMERICANA

  • 1 October 1996
I review methodological problems that can lead to false evidence for selection on secondary sexual characters and present a study of selection in rubyspot damselflies (Hetaerina americana) thatExpand
CAROTENOID LIMITATION AND MATE PREFERENCE EVOLUTION: A TEST OF THE INDICATOR HYPOTHESIS IN GUPPIES (POECILIA RETICULATA)
Abstract Under the indicator models of mate choice, female preferences evolve to exploit the condition-dependence or “indicator value” of male traits, which in turn may cause these traits to evolveExpand
Carotenoid scarcity, synthetic pteridine pigments and the evolution of sexual coloration in guppies (Poecilia reticulata)
Carotenoid–based sexual coloration is the classic example of an honest signal of mate quality. Animals cannot synthesize carotenoid pigments and ultimately depend on dietary sources. Thus, inExpand
