ABSTRACT Physiological mechanisms underlie behavioural responses that have important implications for individual fitness. While personality variation is well established in reptiles, the underlying physiological are less understood. Studies on lizards yielded mixed results regarding relationships between traits and parameters, with syndromes, particularly connection physiology, remaining largely unexplored. We assessed relationship thermal Liolaemus multimaculatus , considering sex as an intervening factor. Exploration boldness were compared familiar novel substrates, we correlations preference locomotor performance. found no repeatability any of studied, contrast to performance which exhibited high repeatability. Our do not support occurrence a syndrome, correlation was exploration. Exploratory behaviour differed substrates sexes, females being more exploratory than males. More explorative individuals, females, enhanced at lower temperatures, revealing inverse within observed thermal‐behavioural type. Intersexual differences lizard can be attributed both ecological pressures mechanisms. Intraspecific syndromes increase species' niche, potentially favouring its adaptability environmental change. Previous studies independently explored pressures. However, comprehensive understanding how these interact influence outcomes remains elusive.

Abstract Life history theory emphasizes that finite resources result in allocation trade-offs among the competing interests of self-maintenance, growth, reproduction, and survival. Environmental conditions, particularly during development, can influence these life trade-offs, leading to coupling physiological behavioural traits with strategies. Thus, populations may vary pattern trait covariation, clustering along a fast-slow continuum, termed extended pace-of-life syndrome (POLS) theory. We aimed test how variation ecological conditions their association behaviour physiology by comparing captive bred wild-collected southern rainforest sunskink ( Lampropholis similis ). The skinks were offspring wild-caught skinks, all tests conducted laboratory. found groups differed, on average, growth rate, body condition, thermal preferences, sprint performance, activity. Counter our expectation, exhibited faster pace relative captive-bred despite experiencing more challenging environmental conditions. Furthermore, not detected, nor correlated form syndrome. Studies are needed identify proximate mechanisms causing they lead coupling, or decoupling, traits. Such information will provide vital insight into forces drive evolution

Global warming may accelerate the process of biological invasions, and invasive species that can quickly adapt to new environments will have a negative impact on native species. Animal personalities significant implications for ecology evolution.

ABSTRACT The human‐mediated transportation of stowaway individuals to non‐native regions is a major driver new biological invasions, and the post‐establishment spread invader in its introduced range. In order for successfully establish region, they must survive harsh conditions during journey (e.g., extreme temperatures, cramped spaces, lack food) arrive good condition. However, few studies have investigated impact human‐assisted on behaviour individuals. Here, we examined whether transportation, via both air road, impacted activity exploratory invasive delicate skink ( Lampropholis delicata ). We exposed skinks either flights commercial airliner (total ~2.5 h flight time, car transport to/from airport), or 3 drive car. found that although temperatures experienced by were more variable than those control group lizards, temperature transit remained well within thermal tolerances species. Human‐assisted only had relatively minor skink: plane did not influence behaviour, increased activity, but behaviour. capacity stowaways cope with stress associated key factor success species introductions, subsequent invasion. As such, there should be greater focus behaviours facilitate potential invaders early stages introduction process.
