Skull Ontogeny and Sexual Dimorphism
The skull ontogeny and sexual dimorphism of the plains vizcacha, Lagostomus maximus, is here described from quantitative approaches. The quantitative...
-
Dimorphism and Pathogenesis in Mucor Species
Many pathogenic fungi are dimorphic, in which they switch the morphology between yeast and filamentous forms. This dimorphism has been observed in...
-
Sexual dimorphism of the human fetal pelvis exists at the onset of primary ossification
Human adolescent and adult skeletons exhibit sexual dimorphism in the pelvis. However, the degree of sexual dimorphism of the human pelvis during...

Sexual dimorphism in chronic respiratory diseases
Sex differences in susceptibility, severity, and progression are prevalent for various diseases in multiple organ systems. This phenomenon is...

Sigmoid allometries generate male dimorphism in secondary sexual traits: a comment on Packard (2023)
The detection of male dimorphism has seen numerous statistical advances. Packard has recently criticized a widely used method, reanalyzing data from...

Female preferences for dominant frequency in frogs: constraints and impact on sexual size dimorphism
AmbotuyFavoring males’ specific sexual signals, female preferences play a major role in frogs’ evolutionary process by selecting traits linked to...

Sexual dimorphism in the tardigrade Paramacrobiotus metropolitanus transcriptome
BackgroundIn gonochoristic animals, the sex determination pathway induces different morphological and behavioral features that can be observed...

Sexual dimorphism in the Hungarian golden jackal population: analysing body and skull size and shape
Defining species within the Canidae family is challenging due to morphological convergence, behavioral plasticity, traditional taxonomic limitations,...
-
Influence of sexual dimorphism and dichromatism on reproductive success in a rare native cactus
Identifying plant sexual dimorphic traits is critical in advancing our knowledge on plant–pollinator interactions. For example, dimorphism in floral...

The evolution of sexual dimorphism in Chondrichthyes: drivers, uncertainties, and future directions
Sexual dimorphisms are abundant in natural systems; however, their ecological and evolutionary significance have largely been neglected with respect...

Intraspecific divergence of sexual size dimorphism and reproductive strategies in a polytypic poison frog
Intraspecific variation in body size, both among populations and between sexes, is an important factor influencing life-history strategies. This...
-
Covariation between protandry and sexual size dimorphism is age specific in songbirds
In many migratory songbirds, males arrive earlier at stopover sites and at the breeding grounds (‘protandry’) and older birds precede younger ones,...

Variation in size and shape: sexual dimorphism in the southern banded newt, Ommatotriton vittatus (Caudata: Salamandridae)
One of the main factors creating intraspecific morphological variation, sexual dimorphism (SD) could be expressed as adult male and female animals...

Variation of sexual dimorphism and asymmetry in disease expression of inflammatory arthritis among laboratory mouse models with different genomic backgrounds
Sex difference has shown in the arthritis diseases in human population and animal models. We investigate how the sex and symmetry vary among mouse...
-
The Dynamic Ontogenetic Shape Patterns of Adaptive Divergence and Sexual Dimorphism
The interplay between ecological diversification and sexual dimorphism has been largely overlooked in the literature. Sexually dimorphic species...

Sexual dimorphism and the multi-omic response to exercise training in rat subcutaneous white adipose tissue
Subcutaneous white adipose tissue (scWAT) is a dynamic storage and secretory organ that regulates systemic homeostasis, yet the impact of endurance...

Sexual Dimorphism, Deactivation of Plant Defense, and Attraction of Conspecifics in the Four-Eyed Red Milkweed Beetle (Tetraopes tetrophthalmus)
Herbivorous insects frequently exhibit sexual dimorphism in body size and a variety of other traits. Such differences often lead to distinct...

Transcriptome analysis of sexual dimorphism in dorsal down coloration in goslings
BackgroundIn day-old Hungarian white goose goslings, there is a noticeable difference in dorsal down coloration between males and females, with...
-
Pelvic sexual dimorphism and its association with cranial morphology in Neotropical spiny rats (Rodentia, Echimyidae)
Pelvic morphology in mammals is shaped by several factors, including the functional commitment with parturition. Due to this, some mammalian clades,...

The evolution of body coloration in dung beetles: diel activity and sexual dimorphism
Animal colouration may evolve due to its effects on predator avoidance, reproduction and thermoregulation, and is likely influenced by the organism’s...
