selection on a floral color polymorphism in the tall morning glory (ipomoea purpurea): transmission success of the alleles through pollen.the w locus, a codominant locus influencing floral pigment intensity in the tall morning glory, ipomoea purpurea, is polymorphic throughout the southeastern united states. previous studies suggest that this polymorphism is actively maintained by balancing selection, and that increased selfing accompanied by lack of pollen discounting ("fisher effect") may act to protect the white allele when it is rare. processes that act to protect the dark allele and thus stabilize the polymorphism in conjunct ...199728568811
sexual selection, space, and speciation.a fisherian model of sexual selection is combined with a diffusion model of mate dispersal to investigate the evolution of assortative mating in a sympatric population. females mate with one of two types of polygynous males according to a male's display of one of two sex-limited, autosomal traits; these male traits may be associated with differential phenotypic mortalities. through a fisherian runaway process, female preferences and male traits can become associated in linkage disequilibrium, le ...199728568798
the evolution of mate preferences for multiple sexual ornaments.males of many species use multiple sexual ornaments in their courtship display. we investigate the evolution of female sexual preferences for more than a single male trait by the handicap process. the handicap process assumes that ornaments are indicators of male quality, and a female benefits from mate choice by her offspring inheriting "good genes" that increase survival chances. a new handicap model is developed that allows equilibria to be given in terms of selection pressures, independent o ...199428568273
the darwin-fisher theory of sexual selection in monogamous birds.males of monogamous birds often show secondary sexual traits that are conspicuous but considerably less extreme than those of polygynous species. we develop a quantitative-genetic model for the joint evolution of a male secondary sexual trait, a female mating preference, and female breeding date, following a theory proposed by darwin and fisher. good nutritional condition is postulated to cause females to breed early and to have high fecundity. the most-preferred males are mated by early-breedin ...199028568205
population divergence in sexual ornaments: the white forehead patch of norwegian pied flycatchers is small and unsexy.models of sexual selection suggest that populations may easily diverge in male secondary sexual characters. studies of a spanish population of the pied flycatcher, ficedula hypoleuca, and a swedish population of the closely related collared flycatcher, f. albicollis, have indicated that the white forehead patch of males is a sexually selected trait. we studied the white forehead patch of male pied flycatchers (n = 487) in a norwegian population over seven years. males with large forehead patches ...199928565517
perspective: the theories of fisher and wright in the context of metapopulations: when nature does many small experiments.we critically review the two major theories of adaptive evolution developed early in this century, wright's shifting balance theory and fisher's large population size theory, in light of novel findings from field observations, laboratory experiments, and theoretical research conducted over the past 15 years. ecological studies of metapopulations have established that the processes of local extinction and colonization of demes are relatively common in natural populations of many species and theor ...199828565332
sexual selection by the handicap mechanism.the handicap mechanism of sexual selection by female choice has been strongly criticized because it does not cause sexual selection to reinforce viability selection and it cannot account for the origin of mating preferences. however, several models indicate that the handicap mechanism can have important effects when operating in conjunction with fisher's mechanism in polygynous populations. these models have been criticized because they require that fitness remains heritable indefinitely. i deve ...198928564247
the evolution of costly mate preferences i. fisher and biased mutation.fisher's runaway process is the standard explanation of the evolution of exaggerated female preferences. but mathematical formulations of fisher's process (haploid and additive diploid) show it cannot cause stable exaggeration if female preference carries a cost. at equilibrium female fitness must be maximized. our analysis shows that evolutionary stable exaggeration of female preference can be achieved if mutation pressure on the male character is biased, that is, mutation has a directional eff ...199128563819
a stochastic simulation study on speciation by sexual selection.a two-locus multi-allele sexual isolation model incorporating mutation and genetic drift which was first proposed by nei et al. (1983) is studied here. one locus controls the male mating character, and the other controls female receptivity. all females are assumed to have equal mating success. therefore, the frequencies of female receptivity alleles are changed by mutation, drift, and hitchhiking with male character alleles. without hitchhiking, development of sexual isolation between allopatric ...198528563651

medical image classification based on multi-scale non-negative sparse coding.with the rapid development of modern medical imaging technology, medical image classification has become more and more important in medical diagnosis and clinical practice. conventional medical image classification algorithms usually neglect the semantic gap problem between low-level features and high-level image semantic, which will largely degrade the classification performance. to solve this problem, we propose a multi-scale non-negative sparse coding based medical image classification algori ...201728559133
