conditions”. There is also a possibility that genetics are primarily responsible for the variations. The colours of male lizards can vary, but they are usually orange only, yellow only, orange surrounded by yellow, or grey only throats. The colours can also vary in degree of intensity and are due to different lineages, northern and southern. Males with orange throats tend to be more aggressive when it comes to defending their territory. It is still unclear how the lineages of females impact the expression of their colours especially since females from wither lineage tend to have the same colouration. From this, it can be concluded that throat colour in these lizards is polymorphic, specifically in determining whether the phenotype is yellow or orange. Although both colours are polymorphic, the yellow colour is also greatly influenced by environment and levels of testosterone present. Polymorphism and environmental factors play major roles in colour expression, but it is impossible to say which one is more significant without genomic analysis and linkage mapping.

have not interacted with one another. When encountering a male that he had encountered before aggression was significantly lower. Repeated interactions were shown to more effective in limiting aggression between males. If there has already been a previous encounter, it is less likely that the individual will be a threat to the livelihood or territory of that male. Being able to recognize which lizards they have already encountered gives lizards the opportunity to limit costly interactions. They are able to tell which individuals they have already won or lost to. To distinguish between individuals, the lizards use physical characteristics as opposed to chemical or behavioral cues. This species uses colouration of the throats to distinguish between lizards, similar to how scientist do in experiments. When researchers controlled for throat colouration, it was more difficult for lizards to determine if they had already encountered the lizard. There were similar levels of aggression for familiar and unfamiliar males.

shows that the season in which the females lay the eggs is good indicator of which sex will be seen in the hatchlings and body size, also known as temperature-dependent sex determination. Very low incubation temperatures are often associated with slower, less developed hatchlings. If incubated at a suitable temperature, hatchlings will have a higher body mass. These individuals will also have a higher probability of reproductive success especially in terms of clutch size and offspring body mass. Studies suggest that body mass is also influenced by the length of incubation. Eggs laid closer to the beginning of the season have more time to develop thus giving them more of an opportunity to gain more body mass. On the other hand, those laid later in the season do not have the same opportunity. Larger body sizes provide an advantage to males and females. Males are better able to defend their territories, and females have higher

females. Both southern and northern males are more likely to be rejected by northern females. Southern males also prefer to mate with southern females because they share the same lineage. This suggests that preferences by either sex are driven by behavioral differences regionally. These lizards primarily prefer to mate with partners that are in the same region geographically. Overall, it appears that speciation is primarily driven by sexual selection with neither sex being more selective than the other.

The optimal time for mating in this species is two to three weeks after the females emerge from hibernation. Eggs are typically laid from September to October with most of them being laid earlier in the period. 438:, segmentation, and colouration. Another group also had similar granularity, segmentation, and colouration that differed from the first group. There were very few lizards with in-between phenotypes. However, within the categories, there still is slight variation in the shades of colours of the lizards. Because throat colouration is a discrete trait, it is highly 615:
susceptible to predators. The lizards are least conspicuous when their colour matches the abundant rock colour of their region. When individuals are placed in the opposite region, they are at a much more conspicuous/noticeable. However, individuals can still use behavioral tactics to protect themselves from predators even though they stand out more.

grazing animals impact the population as well. Constant grazing from animals like sheep, cattle, and feral goats reduce the areas where the lizards can hide and live. With fewer hiding places, they are more susceptible to predation. This, in conjunction with human land clearing, causes much less genetic variation within the species.

sexual success. Therefore, the prevalence of bright-coloured throats is maintained in this population of lizards. Based on the conflicting benefits of dull and bright-coloured throats, it is understandable that both morphs have been maintained in this species. Each trait gives a lizard a different evolutionary advantage.

Although there is a lot of diversity in throat colours, the colour variants in the throats are discrete, meaning the morphologies of individual lizards could be placed into specific categories After using objective methods to identify the colour morphs, statistical tests were run.

The intensity of colours in these lizards indicates the amount predation they are susceptible to. As expected, individuals with more brightly coloured bodies are at a higher risk of predation, because they are more easily spotted. In these habitats, the rocks in which the lizards bask are darker, so

Another indicator of aggression is the presence of black chest patches. Males with these patches are not only more aggressive but also more likely to initiate and win fights.

In these lizards, northern males are considered more aggressive than southern males. Orange, northern males are the most aggressive, and southern males are the least aggressive. But, regardless of lineage, males can differentiate their aggression. Aggression occurs at a higher rate when two males

However, bright-coloured throats also give the lizards a fitness advantage because the bright-coloured throats attract more females, and therefore those males are more likely to reproduce. Although the bright-coloured throats increase the likelihood of being eaten by predators, they also increase
