Sexual dimorphism in innate immunity [PDF]
To establish whether variation in innate immunity, as measured by the level of tumor necrosis factor (TNF) in lipopolysaccharide (LPS)-stimulated whole-blood culture, is related to sex or HLA.Normal volunteers (72 women, 159 men) completed questionnaires and donated peripheral blood specimens.

Ground beetles in multiple species vary greatly in the expression of the shape on sexual traits, resulting in a sexual shape dimorphism as a consequence of sexual selection differences.

Sex differences in selection arise for at least two possible reasons: (1) differences originating from anisogamy—the Darwin‐Bateman paradigm—and (2) competition‐driven ecological character displacement (ECD), agnostic of anisogamy.

SEXUAL SIZE DIMORPHISM IN STONE MARTEN (MARTES FOINA, ERXL. 1777) FROM SARNENA SREDNA GORA MTS (BULGARIA) [PDF]
Sexual dimorphism in body size measurements of 65 stone martens was investigated in winter periods (10.12.- 01.03) 2013 to 2017. There was found sexual dimorphism in body size of Stone Marten from Central Bulgaria: males were larger than females.

Filling the gaps in ecology of tropical tiger beetles (Coleoptera: Cicindelidae): first quantitative data of sexual dimorphism in semi-arboreal Therates from the Philippine biodiversity hotspot [PDF]
Background Sexual dimorphism, driven by sexual selection, leads to varied morphological distinctions in male and female insects, providing insights into selection pressures across species. However, research on the morphometric variability within specific

Sexual dimorphism in Ramapithecinae [PDF]
The Ramapithecinae are an extinct, mainly Miocene group of hominoids comprising the genera Sivapithecus and Gigantopithecus. Ouranopithecus and Ramapithecus are other included genera, here regarded as invalid ...

Symmetry is related to sexual dimorphism in faces: data across culture and species. [PDF]
Many animals both display and assess multiple signals. Two prominently studied traits are symmetry and sexual dimorphism, which, for many animals, are proposed cues to heritable fitness benefits. These traits are associated with other potential benefits,

Sexual dimorphism in campylobacteriosis
SUMMARYSexual dimorphism in infectious diseases whereby disease incidence is more prevalent in one gender has been reported repeatedly in the scientific literature. Both behavioural and physiological differences have been suggested as a cause of this gender bias but there is a paucity of data to support either of these viewpoints.

Sexual dimorphism in the South American water snake Helicops polylepis (Serpentes: Dipsadidae)
Sexual selection, fecundity selection and ecological divergence have been the main explanations proposed for the origin and maintenance of sexual dimorphism.
