Not too much has been happening lately. I have noticed that Philipa hasn't actually been spending all of her time out and about. She seems to have a pretty balanced schedule, between lounding in the fern fronds and sleeping in it's base. I've yet to actually see her hunt, but i'm sure she does, by the size of her belly. Either she has been secretly hunting while I'm not there, or she might be pregnant. If she is pregnant, then I have a whole new batch of issues to deal with with the tank. We'll just have to wait and see what happens.
This morning I was finally able to get some shots of Mr. Bugg wandering around aimlessly. He seems to be doing pretty well for himself dispite all of the recent drama. Not surprisingly, I'm pretty sure he's noctournal, judging by the fact that I only ever observe him just before he dissapears into his log for the day.

Jan. 8/09 The Death of John...
Two days ago (Jan 6) John died...
Along with his death I noted the absence of almost all crickets in the system. I believe the cause for this, and the cause for John's death, is due to the rise and then rapid fall in the number of crickets.
Sometime in December, I noted that there were juvenile crickets in the tank, meaning that they were successful in breeding. That means that the number of crickets rose. The crickets seem to eat the plants. Both dead and alive, meaning that the more crickets there are, the less cover there is. Consequently, the lizards would be able to hunt them far more effectively and before the grass could regrow enough cover, the crickets were gone.
With not enough crickets to sustain both lizards, the bigger one, Philipa, took control of the fern (most likely the last good hiding place for the crickets and the lizards alike) and forced John to look elsewhere. This explains why John was always visible and why Philipa was almost never out.
Since John's death Philipa has been making herself far less scarce, which leads me to believe that the main reason for her hiding was to defend her territory. either that, or she is eating too many crickets, still, and soon the tank will be dead. However I will not let another lizard die. I'm going to intervene next time if this happens again, now that I know what to look for.
If her past hiding was to defend her territory, then that opens up a whole new set of questions and possibilities about the psychology and social behavior of these lizards.
If I have a repeat of what happened over the Christmas Break, instead of trying the same technique again, I'm going to rearrange the tank so that there are more ferns, since the fern seems to be the focal point of almost all the lizards' behaviors.

It's been going really slow lately... Not much change at all... The fern seems to be doing well. The ammount of dead leaves and stems on it seem to be diminishing slowly. It must like the tank...

| It's been a while. Not too much has changed though... I've seen a bit less of John lately. He's been sleeping more in the fern. The beetle is still living in the end of the log. One of the holding tank lizards died... I'm not sure why... Other than that though, not much has really changed at all... |

Monday December 8 2008
Ok so once again it's been too long. The lizards have been out a lot lately. I have noticed some new grass growing though beyond where the grass was growing before. This is a surprise to me, I would have thought that grass would have grown wherever it could have already and not be able to spread... just a thought. I did also notice the beetle is still out and about.

Dec. 1/08
So this moring I noticed there are a fair few dead crickets. There are three dead, full grown crickets. This is good news though because crickets die once they breed. I also noticed several tiny pinhead crickets running around. I'm hoping that this means there are more baby crickets sleeping, since I'm relatively sure that crickets are noctournal.
So this is great news! The crickets are breeding!

Nov. 29/08
I woke up this morning to find both the lizards in the Eco tank sleeping perfectly ballanced on the fronds of the fern, like little iguannas. This does make me wonder if I'm getting real natural responses out of them... would they be so comfortable if they had some predators like wild lizards? of course that's pretty much irrelivant to the project and there's no way I would ever test that theory without actually going to Asia to research them in the wild. (Something I'd personally love to try).
I also noticed a fairly large beetle in there. Probably about a centimeter long in total. He must have come from the dirt... But he looks a lot like a superworm beetle. Maybe one snuck past me when I was initially setting up the tank....
We'll see.
