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 …

Brain size of the lion (Panthera leo) and the tiger (P-tigris): implications for intrageneric phylogeny, intraspecific differences and the effects of captivity
Intraspecific encephalization of the lion and the tiger is investigated for the first time using a very large sample. Using cranial volume as a measure of brain size, the tiger has a larger brain relative to greatest length of skull than the lion, the leopard and the jaguar. The Asian...Yamaguchi, Nobuyuki ; Kitchener, Andrew C ; Gilissen, E ; Macdonald, David W
