Pre-copulatory choices drive post-copulatory decisions: mechanisms of female control shift across different life stages
BackgroundThe ‘wallflower’ hypothesis proposes females mate indiscriminately to avoid reproductive delays. Post-copulatory mechanisms may then allow...

Condition-dependent differences in male vibratory pre-copulatory and copulatory courtship in a nuptial gift-giving spider
AbstractCondition-dependent secondary sexual traits and signals are often crucial for mate choice decisions. Nuptial gifts, provided by the male to...

Mediterranean Spur-thighed Tortoises (Testudo graeca) exhibit pre-copulatory behavior particularly under specific experimental setups
The pre-copulatory behavior of the Mediterranean Spur-thighed Tortoise ( Testudo graeca ), especially the means by which males and females find each...

Do male reproductive traits evolve at the intraspecific level in response to the amount of placentotrophy in a genus of viviparous fishes?
Placentotrophy is a particular type of maternal provisioning to develo** embryos, in which mothers actively provide nutrients via complex placental...

Effect of rearing density on the expression of fitness-related traits in male sand field crickets (Gryllus firmus)
Rearing density has profound effects on life-history decisions for develo** organisms because, for example, it can foreshadow the sexual...

Predaceous Diving Beetle Sexual Systems
Diving beetles have an impressively diverse array of morphological and behavioral attributes associated with sexual systems. These include anatomical...

Despite genetic isolation in sympatry, post-copulatory reproductive barriers have not evolved between bat- and human-associated common bedbugs (Cimex lectularius L.)
BackgroundThe common bedbug Cimex lectularius is a widespread ectoparasite on humans and bats. Two genetically isolated lineages, parasitizing...

Reproductive behaviour of predaceous ladybirds (Coleoptera: Coccinellidae): A review
Sexual activities of predaceous ladybirds (Coleoptera: Coccinellidae) involve complex interactions. Hence, we reviewed information on pre-mating,...

Reddish male swallows have short sperm
Sexual selection favors the evolution of pre-copulatory sexual traits such as ornamentation and post-copulatory sexual traits such as long sperm, but...

Cryptic Mate Preference in Male Bicyclus anynana Butterflies
While male mate choice has received sparse attention in comparison to female choice, it occurs often in insects. In addition, male insects may...

Influence of artificial selection for duration of death feigning on pre- and post-copulatory traits in male Tribolium castaneum
In many animals, investment in anti-predator traits can affect reproductive success. Conversely, males that invest more resources in mating success...

Female-limited X chromosome evolution reveals that lifespan is mainly modulated by interlocus rather than intralocus sexual conflict
AbstractSexual dimorphism in somatic investment may be shaped by two distinct forms of sexual conflict; under intralocus sexual conflict (IASC),...

Differential allocation in a gift-giving spider: males adjust their reproductive investment in response to female condition
BackgroundWhen males are selective, they can either reject low-quality females or adjust their reproductive investment in response to traits that...

Lack of Female Preference for Nuptial Gifts May Have Led to Loss of the Male Sexual Trait
Evolutionary loss of sexual traits may occur if the forces that maintain those traits weaken or disappear. Females may evolve resistance or a change...

Reproductive behavior, seasonality, and distribution of three devil ray species (Mobula mobular, M. thurstoni, and M. munkiana) in the Southern Gulf of California, Mexico
We examined the reproductive behavior (courtship and mating), seasonality and its distribution in three Mobula species, spinetail, bentfin, and...

Do males that experience weapon damage have greater reproductive potential than intact males in polygynous scenarios?
AbstractMales with damaged weapons often lose intraspecific contests; however, recent research suggests these males may use post-copulatory means to...

Mating behaviour of the large-head resin bee Heriades truncorum (Megachilidae: Osminii) suggests female plastic strategy in selection of a mating partner and male quality assessment
Behavioural courtship display and size of males are two attributes often used by females to select a mating partner. According to sexual selection,...

Timing matters: female receptivity and mate choice in the zebrafish (Danio rerio)
AbstractFemale choice has been documented in many animal taxa, and how we test it has been refined through years of studies on the topic. However,...

Lack of discrimination of sex and maturity of conspecifics in the copulation attempts of the male stalk-eyed fly, Sphyracephala detrahens (Diptera: Diopsidae)
Among insects, males have evolved the ability to discriminate potential mates to avoid vain mating attempts. In Diptera, courtship and mating...

Spermatophore retention may accommodate sexual signal loss in Pacific field crickets
AbstractSexual signals are gained and lost over evolutionary time. While signal gain has obvious fitness benefits, signal loss should present...
