Sexual dimorphism in flowering phenology traits may have evolved under sexual selection and vector-mediated selection. The conspicuous sexual dimorphism and sex-specific selection pressures in flowering phenology traits have been investigated mainly in entomophilous dioecious plants, whereas little is known about this in anemophilous plants.

Sexual dimorphism often arises as a response to selection on traits that improve a male's ability to physically compete for access to mates. In primates, sexual dimorphism in body mass and canine size...
Understanding the mechanisms causing phenotypic differences between females and males has long fascinated evolutionary biologists. An extensive literature exists on animal sexual dimorphism but less i...
Tropical plant species are already suffering the effects of climate change and projections warn of even greater changes in the following decades. Of particular concern are alterations in flowering phe...

Phenology is a harbinger of climate change, with many species advancing flowering in response to rising temperatures. However, there is tremendous variation among species in phenological response to w...

Disturbances in sexual desire and the psychophysiologic changes that characterize the sexual response cycle and cause marked distress and interpersonal difficulty. (APA, DSM-IV, 1994)
The selection or choice of sexual partner in animals. Often this reproductive preference is based on traits in the potential mate, such as coloration, size, or behavioral boldness. If the chosen ones are genetically different from the rejected ones, then NATURAL SELECTION is occurring.
A sexual disorder occurring in a person 16 years or older and that is recurrent with intense sexually arousing fantasies, sexual urges, or behaviors involving sexual activity with a prepubescent child (generally age 13 or younger). (from APA, DSM-IV, 1994).
The processes of anatomical and physiological changes related to sexual or reproductive functions during the life span of a human or an animal, from FERTILIZATION to DEATH. These processes include SEX DIFFERENTIATION; SEXUAL MATURATION; and changes during AGING.
This discipline concerns the study of SEXUALITY, and the application of sexual knowledge such as sexual attitudes, psychology, and SEXUAL BEHAVIOR. Scope of application generally includes educational (SEX EDUCATION), clinical (SEX COUNSELING), and other settings.
The World Health Organization (WHO) definition of sexual health; "the state of physical, emotional, mental and social well-being related to sexuality; it is not merely the absence of disease, dysfunction and infirmity. Sexual health requires a posit...
