Sex, Age, and Population Density Affect Aggressive Behaviors in Island Lizards Promoting Cannibalism
Island populations may evolve distinct behavioral repertoires as a response to the conditions of insular life. Strong intraspecific competition is typical in insular lizards and may include cannibalism.

ABSTRACT The development and maintenance of sexually dimorphic behavior often depends on gonadal steroids. Interspecific variation in the magnitude of behavioral sex differences may be mediated by differences in steroid action on neural circuits controlling behavior.

The Interplay of Ontogeny and Phylogeny at the Transcriptome Level of the Tetrapod Heart
The main stages of development during which species‐specific heart anatomy is determined in the ontogeny of representative tetrapods. Transcriptomic similarity is expected earlier in development before heart anatomy diverges. ABSTRACT The tetrapod heart is characterized by three chambers in amphibians and non‐avian reptiles, as opposed to four in birds,

Abiotic constraints on the activity of tropical lizards
Summary 1. Many tropical ectotherms are considered vulnerable to anthropogenic climate change because they have evolved to become thermal specialists. Indeed, several recent studies have suggested that even small increases in mean operative temperature ...

The impact of gigafire on vegetation structure, terrestrial vertebrate abundance and diel activity
Fire regimes are shifting around the world due to climate and land‐use change, resulting in an increased frequency of large and severe wildfires. However, the impact of extreme wildfire events on animal species remains poorly understood. Particularly lacking is an understanding of how fire affects animal behaviour.
