Host sexual dimorphism and parasite adaptation [PDF]
, 2012 In species with separate sexes, parasite prevalence and disease expression is often different between males and females. This effect has mainly been attributed to sex differences in host traits, such as immune response.

International Forum of Allergy &Rhinology, EarlyView.ABSTRACT Background Bitter taste receptors (T2Rs) function in the innate immune defense of the sinonasal mucosa; however, the genetic association between the TAS2R gene family and chronic rhinosinusitis (CRS) remains understudied in Asian populations.

Sexual dimorphism of head, teeth, flipper and body size in northern elephant seals (Mirounga angustirostris) throughout ontogeny [PDF]
Royal Society Open ScienceSexual dimorphism, the difference in appearance between males and females of the same species, can shape physiology, behaviour and fitness. Yet, few species have age- and sex-specific data to characterize its development.

The Anatomical Record, EarlyView.Abstract The oval window (OW) is an opening connecting the inner and middle ear. Its area has been shown to consistently scale with body mass (BM) in primates, and has been used alongside semi‐circular canal (SCC) size to differentiate Homo sapiens and fossil hominins, including Paranthropus robustus.

Sexual dimorphism in the incidence of human cancers
BMC Cancer, 2019 Background Sex differences in the incidences of cancers become a critical issue in both cancer research and the development of precision medicine. However, details in these differences have not been well reported.

The Anatomical Record, EarlyView.We describe the functional anatomy of masticatory muscles in nine opossums, finding a generalized anatomical pattern with differences related to skull morphology. Variation in quantitative myological data and estimated bite force was mostly related to size, and the increase in bite force supports dietary diversification associated with size increase ...

Sexual Selection for Male Mobility in a Giant Insect with Female‐Biased Size Dimorphism [PDF]
, 2008 Female-biased size dimorphism in which females are larger than males is prevalent in many animals, but the factors causing this pattern of dimorphism are still poorly understood.

The Anatomical Record, EarlyView.Abstract Domesticated European rabbits (Oryctolagus cuniculus) have long been chosen as laboratory model organisms. Despite this, there has been no definitive study of the vertebral musculature of wild rabbits. Relevant descriptions of well‐studied veterinary model mammals (such as dogs) are generally applicable, but not appropriate for a species ...

Sexual dimorphism for juvenile body weight in chickens divergently selected for 8-week body weight
Frontiers in PhysiologyThere is a dearth of literature on the genetics of sexual dimorphism for juvenile body weight in meat-type chickens given its biological and economic relevance. Herein, we report the sexual dimorphism for 4- and 8-week body weights in White Plymouth Rock
