Phenotypic plasticity determines differences between the skulls of tigers from mainland Asia
Tiger subspecific taxonomy is controversial because of morphological and genetic variation found between now fragmented populations, yet the extent to which phenotypic plasticity or genetic variation affects phenotypes of putative tiger subspecies has not been explicitly addressed. In order to assess the role of phenotypic plasticity in determining skull variation,... -

Distinguishing the victim from the threat: SNP‐based methods reveal the extent of introgressive hybridization between wildcats and domestic cats in Scotland and inform future in situ and ex situ management options for species restoration
The degree of introgressive hybridization between the Scottish wildcat and domestic cat has long been suspected to be advanced. Here, we use a 35‐SNP‐marker test, designed to assess hybridization between wildcat and domestic cat populations in Scotland, to assess a database of 295 wild‐living and captive cat samples, and test...Senn, Helen ; Ghazali, Muhammad ; Kaden, Jennifer ; Barclay, David ; Harrower, Ben …

Rensching cats and dogs: feeding ecology and fecundity trends explain variation in the allometry of sexual size dimorphism
The tendency for sexual size dimorphism (SSD) to increase with body mass in taxa where males are larger, and to decrease when females are larger, is known as Rensch's rule. In mammals, where the trend occurs, it is believed to be the result of a competitive advantage for larger males,...Johnson, P J ; Noonan, M J ; Kitchener, Andrew C ; Harrington, L A ; Newman, C …

Sexual size dimorphism in musteloids: An anomalous allometric pattern is explained by feeding ecology
Rensch's rule states that sexual size dimorphism (SSD) increases with body size in taxa where males are larger, and decreases when females are larger. The dominant explanation for the trend is currently that competitive advantage for males is greater in larger individuals, whereas female size is constrained by the energetics...Noonan, M J ; Johnson, Paul J ; Kitchener, Andrew C ; Harrington, L A ; Newman, C …
