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,...
-
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...

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...

Sexual selection leads to positive allometry but not sexual dimorphism in the expression of horn shape in the blue wildebeest, Connochaetes taurinus
Sexual selection is thought to be an important driver of adaptation, speciation and extinction. Empirically testing these predictions across...

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...

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...

Relative importance of the environment and sexual dimorphism in determining shell shape in the Amazonian freshwater mussel Castalia ambigua (Unionida: Hyriidae) along a hydrological gradient
Shell shape variation of the freshwater mussel Castalia ambigua in relation to environmental and genetic drivers remains unresolved in South America....

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...

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,...

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,...

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...

Sex Ratio, Sexual Dimorphism, and Wing Geometric Morphometrics in Species of Trypoxylon Latreille, 1796 (Hymenoptera: Crabronidae)
Studying the nesting biology of wasp and bee species provides valuable insights into the ecology and evolution of these insects, shedding light on...

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...

Craniodental Sexual Dimorphism Among Hylobatids
Sexual dimorphism has been widely documented in primates, however craniodental sexual dimorphism among hylobatids has not been well researched. In...

Sex Inversion, Sexual Dimorphism, and Morphological Differences of Spicara flexuosa (Sparidae)
AbstractMale and female Spicara flexuosa (Rafinesque, 1810) may be considered as two distinct stocks whose population can be monitored and managed...
-
Sexual dimorphism in Athene cunicularia: are visual cues clues?
Sexual dimorphism occurs when males and females of a given species are clearly distinguishable from one another, regarding size, color, or shape, and...

Sexual dimorphism in toothed whales (Odontoceti) follows Rensch’s rule
Rensch’s rule entails that male-biased sexual size dimorphism scales allometrically with body size and is assumed to generally apply to polygynous...

Sexual dimorphism in the fish Dormitator maculatus (Teleosti: Eleotridae) from Alvarado Lagoon, Veracruz, Mexico
The shape of the urogenital papilla is used to visually determine the sexual dimorphism of Dormitator maculatus . However, it is occasionally not...

Sexual Dimorphism in the Ontogeny of the Black Forest–Steppe Adder (Pelias berus nikolskii (Vedmederja, Grubant et Rudaeva 1986), Serpentes, Viperidae) from Voronezh Oblast, Based on Traditional Measurements
AbstractMales and females of the black forest–steppe adder ( Pelias berus nikolskii ) inhabiting Voronezh oblast, apart from differences in tail...

Evolutionary allometry of sexual dimorphism of jum** performance in anurans
Sexual dimorphism is a common feature in animals, yet the degree of sexual dimorphism is not constant across taxa. Sometimes the magnitude of sexual...
