Functional morphology of immature mating in a widow spider [PDF]

Frontiers in Zoology, 2021
Background Mating generally occurs after individuals reach adulthood. In many arthropods including spiders, the adult stage is marked by a final moult after which the genitalia are fully developed and functional.

Alternative mating tactics in brown widow spiders: mating with or without male self-sacrifice does not affect the copulatory mechanism. [PDF]

Front Zool
Background Male self-sacrifice during mating is one of the most extreme forms of male reproductive investment. In two species of widow spiders (genus Latrodectus), males trigger sexual cannibalism by “somersaulting” into the fangs of the female after ...

Pre-copulatory choices drive post-copulatory decisions: mechanisms of female control shift across different life stages

BMC Ecology and Evolution, 2023
Background The ‘wallflower’ hypothesis proposes females mate indiscriminately to avoid reproductive delays. Post-copulatory mechanisms may then allow ‘trading up’, favouring paternity of future mates.

Transcriptome profiling of sexual maturation and mating in the Mediterranean fruit fly, Ceratitis capitata. [PDF]

PLoS ONE, 2012
Sexual maturation and mating in insects are generally accompanied by major physiological and behavioural changes. Many of these changes are related to the need to locate a mate and subsequently, in the case of females, to switch from mate searching to ...

Dynamic Changes in the Phenotype of Dendritic Cells in the Uterus and Uterine Draining Lymph Nodes After Coitus

Frontiers in Immunology, 2020
Dendritic cells (DCs) are essential for successful embryo implantation. However, the properties of uterine DCs (uDCs) during the implantation period are not well characterized.

Does Male Care, Provided to Immature Individuals, Influence Immature Fitness in Rhesus Macaques? [PDF]

PLoS ONE, 2015
Among many mammals, maternal care strongly impacts infant survival; however, less is known about whether adult males also affect infant fitness. Paternal care is expected when providing care enhances offspring survival and reproduction, which likewise ...

First documentation of putative mating behavior in blue sharks (Prionace glauca) reveals a potential reproductive area in the Northeast Atlantic [PDF]

Web Ecology
Reproductive behavior in sharks remains poorly understood, with direct observations of mating reported in only a few species. The blue shark (Prionace glauca) is a widely distributed, placental viviparous species, yet direct evidence of mating behavior ...

MAT1-1-3, a Mating Type Gene in the Villosiclava virens, Is Required for Fruiting Bodies and Sclerotia Formation, Asexual Development and Pathogenicity

Frontiers in Microbiology, 2020
Villosiclava virens is the prevalent causative pathogen of rice false smut, a destructive rice disease. Mating-type genes play a vital role in the evolution of mating systems in fungi.
