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 . . . → Read More: How will global warming affect egg-laying and live-bearing species?

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 . . . → Read More: Competing through eating: lessons from a lizard

Up for a fight or doing a runner, for a lizard it could be in their genes

Animals often instinctively assess their environment, and display innate behavioural responses. For example, many newly born reptiles and fish know how to respond to predators – knowing when to “fight” and when to “flee” – right after hatching out of their eggs! Innate behavioural responses, especially in times of peril, may be the difference . . . → Read More: Up for a fight or doing a runner, for a lizard it could be in their genes

The Bluetongue interviews

There was some interest in our recent paper on bluetongue lizards (blueys) and why they have this amazing blue tongue, which is actually a UV-blue tongue. (See our previous blog post.)

Why blue tongue? A potential deimatic display has been uncovered in blue-tongue skinks

An enduring question among fans of blue-tongue lizards is why the blue tongue? Why have such an outrageously coloured tongue, given that the vast majority of lizards have a regular old pink tongue? Blueys (bluetongue skinks) are something of an Australian icon. They are part of Australian folklore and most Australians have encountered them . . . → Read More: Why blue tongue?

Dispatches from the field: new adventures with endangered crocodile lizards and oriental garden lizards

It’s been a very busy year, which explains why I am only now writing this blog post from my trip to China earlier this year (May-June). I had the amazing opportunity of seeing one of the world’s most endangered lizards—the crocodile lizard (Shinisaurus crocodilurus), in the wild, and working with one of the largest . . . → Read More: Dispatches from the field: new adventures with endangered crocodile lizards and oriental garden lizards

Turn up the colour: male frogs use bright colours to avoid confusion at the pond

Imagine being a frog during the chaos of the breeding season and navigating the gathering crowds around the pond.
