We are excited to present the very first "Youngzine Live!" series by Aaron Reedy. Aaron and the rest of the team are working on a National Geographic funded Lizard Project and are passionate about bringing science from the field to classrooms. Meet the 3 members of the team here.

From March 28 to April 10, they will be providing field updates from the islands of Florida, and answering questions from Youngzine readers and classrooms. Be sure to check out this page everyday, read the latest blogs and tweets, and ask any questions that come to your mind!

Aaron Reedy will be doing live sessions with interested children/classrooms on his return. If you would like to participate, please send us an email at editor@youngzine.com

Day 5 & 6: Lots of Lizards!

Anole Eating Anole!

Today we had another first for the Lizard Project.  While on island H capturing lizards, we found a green anole eating a brown anole.  While other people had previously observed this happening, we had not seen this on our islands, until today. 

As I was looking for lizards, some rustling on a nearby palm frond got my attention.  Expecting it to be a lizard to noose, I crouched down ready to capture it.  Thats when I found an adult green anole munching on a hatchling brown anole. The brown anole was still alive and struggling, but looked like the struggle was going to be futile.  This was an exciting find for us.

We found eggs!

Earlier this week I wrote a post about a nest-site choice study that Aaron and Dan had done in the lab. However, anole nests are notoriously difficult to study in the field- very little is known about anole nesting. However today, we found two anole eggs on one of our islands, which was very exciting for us.

Reptiles have varied reproductive  strategies.  Some give live birth, which is known as viviparity. Most reptiles, however, are oviparous, which means they lay eggs.  And most of these oviparous reptiles lay many eggs in a single clutch.  Anoles, however, lay a single egg at a time.  We are not certain why anoles lay only one egg, but this is a question some evolutionary biologists have studied.  One hypothesis is that the female can escape predators more easily by only carrying one egg at a time. There are many other intriguing hypotheses, however.

Whatever the reason, we were excited to find two anole nests (which consisted of one egg each!). Check it out
