How will global warming affect egg-laying and live-bearing species? We asked one of the most extraordinary lizards in the world

By Iván Beltrán Environmental temperature determines many important aspects of an animal’s life. In ectotherms, commonly known as ‘cold-blooded’ animals, the temperature experienced during embryonic development significantly impacts a hatchling’s physiology and behaviour. For instance, nest temperatures determine offspring sex in turtles and crocodilians and affect body size in squamates, a group comprised of lizards […]

Do I, or don’t I? Are lizards capable of inhibitory control?

Blog post by Sebastian Hoefer We often think of reptiles as somewhat simple – entirely driven by instinct and the basic need for survival. That is where the expression “Reptilian Brain” comes from. It is certainly true that the anatomy of the reptile brain is different from that of mammals, however, we do not know […]

Competing through eating: lessons from a lizard

Post by Isabel Damas One way invasive species can have a major impact on ecosystems, is by threatening native species, particularly through competition for resources. Animals typically use two strategies to out-compete their opponents: they can be directly aggressive (termed interference competition), or they can indirectly out-compete rivals by consuming more resources (exploitative competition). Our new […]

Dispatches from the field: following the Sulawesi Forest Turtle

Note, this field work formed the basis for Angela’s Masters thesis. By Angela Simms I wasn’t sure what to expect on the first night searching for the Sulawesi Forest Turtle. As little as 30 minutes into the stream walk, our local guide spots a large male perched on the edge of the clear shallow flowing […]

Blue-tongue lizards are born smart, at least as smart as their parents!

By Birgit Szabo As children we have much to learn after we are born. We learn to walk, to talk, to develop our social skills, and when we start school we learn how to read, write and do maths. ​Humans, and many other animals, are considered altricial, meaning that juveniles need to be taken care […]

Hot off the press! An invasive lizard species can learn from other species

Check out our new paper on social learning in the Italian wall lizard, Podarcis sicula. This work formed part of Isabel Damas’ PhD thesis, and it was a huge effort! The question of what makes an invasive species successful compared to other species, that may fail to gain a foothold in a new location, is […]

What tree skinks know about change: A story in colour and shape

Note from Martin Whiting: This blog posts details a chapter of Birgit Szabo’s PhD recently published in Animal Behaviour and represents an enormous amount of work. Birgit did a 9-month cognition experiment, which could be the longest lizard cognition experiment thus far conducted. (Let us know if it isn’t!) The work is in collaboration with […]

Come on a tour of The Lizard Lab

This is a behind-the-scenes video tour of the lab. We will show you our research facilities, some of our study animals, and our lizard enclosures. This video was entirely put together by Cooper Van De Wal. Cooper is a student at Macquarie and volunteers in the lab. He also has his own, highly successful YouTube […]
