A non‐invasive geometric morphometrics method for exploring variation in dorsal head shape in urodeles: sexual dimorphism and geographic variation in …
The study of morphological variation among and within taxa can shed light on the evolution
of phenotypic diversification. In the case of urodeles, the dorso‐ventral view of the head …

Overall trends vs. individual trajectories in the second‐to‐fourth digit (2D: 4D) and metacarpal (2M: 4M) ratios during puberty and adolescence
Objectives The second‐to‐fourth digit ratio (2D: 4D ratio) can be assumed a valid indicator
of sexual differentiation, provided that it is stable once it develops, or eventual changes …

Flesh and bone: An integrative approach towards sexual size dimorphism of a terrestrial salamander (genus Salamandrina)
P Pogoda, A Kupfer - Journal of Morphology, 2018 - Wiley Online Library
Males and females face different selection pressures due to a sexually biased investment
into reproduction. This often results in different morphologies. Sexual size dimorphisms …

Mixed Sex Effects on the Second‐to‐Fourth Digit Ratio of Túngara Frogs (Engystomops pustulosus) and Cane Toads (Rhinella marina)
Sexual dimorphism in the ratio of digit lengths has been correlated to behavioral,
physiological, and morphological traits in a variety of taxa. While sexual dimorphism in the …

Digit identity matters: origin and evolution of sexual dimorphism in the digit lengths of tropidurid lizards
Sexual dimorphism in digit lengths reflects phenotypic evolution mediated by developmental
steroids. Differences in the identity of the sexually-dimorphic digit may evolve if the …

Side-specific effect of yolk testosterone elevation on second-to-fourth digit ratio in a wild passerine
Second-to-fourth digit ratio is a widely investigated sexually dimorphic morphological trait in
human studies and could reliably indicate the prenatal steroid environment. Conducting …

Digit ratio in the common spadefoot toad Pelobates fuscus (Anura: Mesobatrachia: Pelobatidae): patterns and correlations
Digit ratio (DR or 2D: 4D), an indicator based on the relative length of the second and fourth
digits, has been linked to embryonic sex hormone levels and is regarded as a biomarker for …

Absence of sex differences in digit ratio in nestlings of the White Stork Ciconia ciconia, a monomorphic bird species
Capsule There were no statistically significant differences in digit ratio between male and
female chicks of the White Stork Ciconia ciconia. Aims To test the hypothesis that the ratio of …
