Sexual dimorphism in lizards is determined by ecological and environmental factors.
Broadly distributed species may show variation in patterns of sexual dimorphism toward …

Morphology and resource use have a significant influence on lizard population dynamics. In
this study, sexual dimorphism and feeding ecology were assessed in a population of …

Determining the age of any species allows it to be analyzed from the ontogenetic,
demographic, and ecological perspectives. In the present study, we tested the hypothesis …

Populations and chromosomal races of a species often show variation in life-history
characteristics due to phylogeny and environmental factors. We analysed variation in snout …

The goal of this study is to describe patterns of reproductive activity and associated
characteristics in a lizard community from an arid environment in the southern Chihuahuan …

Variation in life history traits can arise from both genetic and environmental factors. We
investigated reproductive activity and variation in some life history traits among four lizard …

Populations of the same species that inhabit contrasting environments may be subject to
different selection pressures, promoted by the local environment. Therefore, the individuals …

Personality defined as individual differences in behavioural traits, which are consistent
through time and across situations, has been observed among individuals of the same …

We analysed size (snout–vent length, SVL), body mass, reproductive cycles, and
reproductive characteristics (litter size) of a population of the viviparous lizard Abronia …

We attempted to identify the factors influencing size and shape dimorphism between sexes,
as well as among populations and species in the Sceloporus scalaris group (Sceloporus …
