The human-assisted movement of species beyond their native range facilitates novel interactions between invaders and native species that can determine whether an introduced species becomes invasive and the nature of any consequences for native commun

The mechanisms that mediate the interaction between the thermal environment and species ranges are generally uncertain. Thermal environments may directly restrict species when environments exceed tolerance limits (i.e. the fundamental niche). However

The Common Wall Lizard (Podarcis muralis) has existed in southwestern British Columbia since 1967, but expanded its range rapidly in the last decade. In 2006, P. muralis was thought restricted to 4 populations on southeastern Vancouver Island: 3 on t

In response to conditions that threaten homeostasis and/or life, vertebrates generally increase production of glucocorticoid hormones, such as corticosterone (CORT), which induces an emergency physiological state referred to as the stress response. G

Bite force capacity is a directly related performance correlate of head shape and is an integrative measure of performance in capturing and handling prey, fighting, and mating, especially for males. We investigated head shape and bite force dimorphis

Among 21 species for which information is available (out of ca. 100 extant species), three diploglossines, five gerrhonotines, and six anguines attend their eggs during incubation, implying that parental behavior might be synapomorphic for the more i

Introduced species represent one of the greatest potential threats to persistence of native species. Therefore, it is important to understand the ecology of introduced species in order to develop appropriate mitigation strategies if required. In this

Many reptiles have different habitat requirements for different activities (e.g., hibernation and nesting/gestation) that may not be satisfied by a single location. Suitable habitat may not only be limited, but also fragmented, making it difficult fo

Minimising predation risk is critical to fitness in all animals. For animals that utilise retreat sites as an anti-predator strategy, there are many factors that influence retreat site selection an...

Strike-induced chemosensory searching (SICS), including a post-strike elevation in tongue-flick rate (PETF) and searching movements following experimental removal of prey from the predator's mouth, is demonstrated to occur in an anguid lizard, Elgari
