A male-specific doublesex isoform reveals an evolutionary pathway of sexual development via distinct alternative splicing mechanisms
The doublesex / mab-3 related transcription factor ( Dmrt ) genes regulate sexual development in metazoans. Studies of the doublesex ( dsx ) gene in...

Chemical cues in the mating behavior of a highly polygynous bird
Visual and auditory signals are well-established components of avian courtship, but the role of chemical signaling remains poorly understood,...

Cellular diversity and gene expression profiles in the male and female brain of Aedes aegypti
BackgroundAedes aegypti is a medically-important mosquito vector that transmits arboviruses including yellow fever, dengue, chikungunya, and Zika...

Reproductive Behavior and Stridulatory Communication in Sternochetus mangiferae (Coleoptera: Curculionidae: Cryptorhynchinae)
Sternochetus mangiferae (Coleoptera: Curculionidae) is an important pest of mango trees around the world. This work aimed to investigate the...

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...

Reproductive behavior analysis in the annual killifish Austrolebias nigripinnis (Regan, 1912) (Cyprinodontiformes: Rivulidae)
Annual killifish have an annual life cycle unique among vertebrates. Adults lay desiccation-resistant eggs in the soil of the temporary pools they...

Problem Solving, Ballet Courtship and the Fox Alarm: How Do Cranes Communicate with Each Other?
The crane pair that again nested where they had been robbed of their eggs the previous year worried me more and more, because there was no meadow at...

Listening in: the importance of vibratory courtship signals for male eavesdrop** in the wolf spider, Schizocosa ocreata
AbstractMultimodal courtship signals may compensate for environmental interference or loss of signals in some sensory modes but may also increase...

Influence of female cuticular hydrocarbon (CHC) profile on male courtship behavior in two hybridizing field crickets Gryllus firmus and Gryllus pennsylvanicus
BackgroundThe hybridizing field crickets, Gryllus firmus and Gryllus pennsylvanicus have several barriers that prevent gene flow between species....

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...

Male age and sexual experience affect male mating behavior in the hawthorn spider mite, Amphitetranychus viennensis
As is reported, in species with first-male sperm precedence, male age and previous sexual experience play crucial roles in male mating behavior. In...

Late mating behaviour in European brown bears
Brown bears ( Ursus arctos ) usually mate in spring throughout their global range, although a few cases of breeding activity are known in late summer...

Carotenoid skin ornaments as flexible indicators of male foraging behavior in a marine predator: Variation among Mexican colonies of brown booby (Sula leucogaster)
Carotenoid-dependent ornaments can reflect animals’ diet and foraging behaviors. However, this association should be spatially flexible and variable...
-
Reproductive effort affects subsequent horn growth in sexually dimorphic male ungulates
Trade-offs between reproductive effort and subsequent growth in males are not well explored, despite their relevance in questions of individual...
-
Background contrast affects detection and recognition of courting wolf spiders by intended and unintended receivers
We used video playback of courting male Schizocosa ocreata wolf spiders to examine responses of intended receivers (conspecific females) and...

Behavioral ecology in co-occurring territorial males of the pupfishes, Garmanella pulchra and Cyprinodon artifrons, at reciprocally asymmetric densities in a mangrove floodplain
Two cyprinodontids, Garmanella pulchra and Cyprinodon artifrons , coexist in a small mangrove floodplain on the Yucatan Peninsula, enabling comparison...

Same-sex sociosexual behaviour is widespread and heritable in male rhesus macaques
Numerous reports have documented the occurrence of same-sex sociosexual behaviour (SSB) across animal species. However, the distribution of the...

Multiple phenotypic traits predict male mating success in a critically endangered frog
AbstractComplex sexual signals spanning multiple sensory modalities may be common in nature, yet few studies have explored how combinations of...

Male Mating Strategy and Preference for Females of Different Maturity Stages in the Small Water Strider, Microvelia iriomotensis (Heteroptera: Veliidae)
Precopulatory mate guarding behavior is a common strategy among males of many species. Although this behavior increases male reproductive success, it...

A shift in the paradigm? A male-specific lactone increases the response of both sexes of the olive fruit fly Bactrocera oleae to the food lure ammonium bicarbonate
The olive fruit fly Bactrocera oleae (Rossi) (Diptera: Tephritidae) is a key pest species of wild and cultivated olive trees worldwide. Contrarily to...
