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

Sexual dimorphism in autoimmunity [PDF]
Journal of Clinical Investigation, 2015 Autoimmune diseases occur when the immune system attacks and destroys the organs and tissues of its own host. Autoimmunity is the third most common type of disease in the United States. Because there is no cure for autoimmunity, it is extremely important to study the mechanisms that trigger these diseases.

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

Can diet niche partitioning enhance sexual dimorphism? [PDF]
, 2022 Classic evolutionary theory suggests that sexual dimorphism evolves primarily via sexual and fecundity selection. However, theory and evidence are beginning to accumulate suggesting that resource competition can drive the evolution of sexual dimorphism ...

The ontogeny of sexual size dimorphism of a moth: when do males and females grow apart? [PDF]
PLoS 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 Osteoclasts [PDF]
Cells, 2020 Osteoclasts are the principal mediators of bone resorption. They form through the fusion of mononuclear precursor cells under the principal influence of the cytokines macrophage colony stimulating factor (M-CSF, aka CSF-1) and receptor activator of NF-κB ligand (RANKL, aka TNFSF11).
