ABSTRACT Egg-mimic, or lollypop darters comprise four species in which breeding males develop large knobs supported by attenuated rays above the second dorsal fin. These structures are presumably the product of sexual selection via female mate choice behavior. I investigated female preference for male fin knobs in three species of egg-mimic darters by experimentally removing fin ornamentation from one of a pair of males and allowing a female to choose between the experimental (non-knobbed) and…

Incipient second dorsal fin egg mimics in the spottail darter, Etheostoma squamicepsl
TLDR
The results suggest that female choice is weak or absent in early stages of knob evolutionary development, and that another mechanism such as genetic drift or an alternate function for knobs may be necessary to produce the larger knobs found in other species.
Disentangling Female Mate Choice and Male Competition in the Rainbow Darter, Etheostoma caeruleum
TLDR
Male interactions, in the form of guarding, appear to play a larger role in determining male mating success than does female choice, and there were no significant correlations between overt aggression and male spawning success.
An Ethological Analysis of the Breeding Behavior of the Fantail Darter, Etheostoma flabellare
TLDR
A model describing the probability of any sequence of behaviors between an egg's deposition and its fertilization and that courtship behaviors occurred through all phases of the spawning events found that the largest males in the study were the only males to successfully mate with females.
Male-male interactions and their influence on the mating behavior and success in the fountain darter, Etheostoma fonticola
TLDR
It is suggested that male size influences dominance relationships in E.fonticola but not mating success, and association preferences in male and female Etheostoma fonticola do not reveal a size preference for same sex or opposite-sex individuals.
Body shape variation in two species of darters (Etheostoma, Percidae) and its relation to the environment
TLDR
The results indicate that even subtle and gradual environmental variation can induce substantial variation in phenotypes on a relatively small spatial scale.

Environmental variation can shape phenotypic variation in organisms. Most evidence for trait differentiation along environmental gradients comes from analyses of dichotomous habitat types that differ…

Egg-mimicry as a mating strategy in the fantail darter, Etheostoma flabellare: females prefer males with eggs
TLDR
Examination of female preference in the fantail darter found that females preferred males with eggs over males without eggs, and males with egg-mimics over males Without eggs, so it appears that female preference for males already guarding eggs may have led to the evolution of specialized egg-Mimicking morphology in males.
Variation in Egg-Mimic Size in the Guardian Darter, Etheostoma oophylax (Percidae)
TLDR
Egg mimics in Etheostoma (Catonotus) oophylax appear before the beginning of the breeding season and reach maximum size in the middle of the season when most spawning activity is expected, and choice of resources, that is, presence or absence of eggs in the nest site, may be more important to females than choice of male.
Morphology and Adaptive Significance of Fin Knobs in Egg-clustering Darters
The fleshy knobs that develop on the fins of breeding male, egg-clustering darters in the subgenera Boleosoma and Catonotus of Etheostoma lack mucous cells. Thus, they probably do not function in…
Truth in Advertising: The Kinds of Traits Favored by Sexual Selection
TLDR
The truth in advertising model describes a mechanism of sexual selection to account for the evolution of the kinds of traits used by males of polygynous species to compete for and attract mates and deemphasizes the traditional dichotomies between the effects ofsexual selection and natural selection.
