Sexual dimorphism in campylobacteriosis

open access: yesEpidemiology and Infection, 2007
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.

Evolution of sexual size dimorphism in mammals: Sexual or natural selection? [PDF]

open access: yes, 2023
Sexual size dimorphism may have evolved through two processes: sexual or natural selection. The sexual selection theory states that males compete for mate monopolization and larger males can sire more offspring than smaller ones—factors that resulted in ...

open access: yesParasites & Vectors, 2015
Background Sexual dimorphism in animals has been studied from different perspectives for decades. In 1874 Darwin hypothesized that it was related to sexual selection, and even after nearly 140 years, when additional empirical data has become available ...

Sexual dimorphism in innate immunity [PDF]

open access: yesArthritis & Rheumatism, 2002
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.

Measuring the Inter and Intraspecific Sexual Shape Dimorphism and Body Shape Variation in Generalist Ground Beetles in Russia

open access: yesInsects, 2020
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.

A lack of sexual dimorphism in width-to-height ratio in White European faces using 2D photographs, 3D scans, and anthropometry [PDF]

open access: yes, 2012
Facial width-to-height ratio has received a great deal of attention in recent research. Evidence from human skulls suggests that males have a larger relative facial width than females, and that this sexual dimorphism is an honest signal of masculinity,

Understanding the evolution of ecological sex differences: Integrating character displacement and the Darwin‐Bateman paradigm

open access: yesEvolution Letters, 2019
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]

open access: yesTrakia Journal of Sciences, 2019
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.
