The ontogeny of sexual size dimorphism of a moth: when do males and females grow apart? [PDF]

open access: yesPLoS ONE, 2014
Sexual dimorphism in body size (sexual size dimorphism) is common in many species. The sources of selection that generate the independent evolution of adult male and female size have been investigated extensively by evolutionary biologists, but how and ...

Sexual Dimorphism in Fin Size and Shape in Bluefin Killifish [PDF]

open access: yesEcology and Evolution
Sexual dimorphism provides insight into how trait optima differ between males and females, despite their shared genome. Measuring sexual dimorphism can help identify which traits have been shaped by sexual selection. While fish morphology has been widely

Sexual Dimorphism in Maxillary Canine Dimensions among Kosovo Population: A CBCT Analysis [PDF]

open access: yesActa Stomatologica Croatica
Dental sexual dimorphism, particularly in maxillary canines, is one of the most reliable markers for sex determination in forensic and anthropological contexts.

Ethnic variability of growth processes through the prism of sexual dimorphism of body dimensions (based on data of early and first childhood children) [PDF]

open access: yesВестник археологии, антропологии и этнографии, 2023
. The study deals with the process of forming of the level and vector of sex somatic differences through early and first childhood, specific peculiarities of sexual dimorphism at 3–6 years of age as compared to the sexual dimorphism of adults, ethnic ...

The function and evolution of a genetic switch controlling sexually dimorphic eye differentiation in honeybees

open access: yesNature Communications, 2023
Sexual dimorphism results in widely diverse animal forms, but sexual determination is generally attributed to a single gene in animal models. Here they find that the glu gene regulates sexual dimorphism of honeybee eyes, demonstrating diversification of ...

Sexual dimorphism in shell shape: is Pomacea canaliculata an exception or an example among Neotropical apple snails? [PDF]

open access: yesAnais da Academia Brasileira de Ciências, 2023
Sexual dimorphism has often been recorded in apple snails (Caenogastropoda Ampullariidae), but reports are concentrated in a few species, either invasive or with biocontrol potential, which sugests some taxonomic bias.

Variation in craniomandibular morphology and sexual dimorphism in pantherines and the sabercat Smilodon fatalis. [PDF]

open access: yesPLoS ONE, 2012
Sexual dimorphism is widespread among carnivorans, and has been an important evolutionary factor in social ecology. However, its presence in sabertoothed felids remains contentious.

Intra- and Interspecific Variation in Sexual Dimorphism Patterns of Mud Crab Genus Scylla Along the Equatorial Region

open access: yesFrontiers in Marine Science, 2021
Sexual dimorphism is generally obvious in brachyurans, and sexual dimorphism between species is of a higher degree to allow separation of trophic niches compared to the lower intraspecific variations between sexes.

Feeding ecology and sexual dimorphism in a speciose flower beetle clade (Hopliini: Scarabaeidae) [PDF]

open access: yesPeerJ, 2018
The relationship between feeding ecology and sexual dimorphism is examined in a speciose South African monkey beetle clade. We test whether feeding and mating at a fixed site (embedding guild) is associated with greater levels of sexual dimorphism and ...
