Posted: 07 Jan 2006 Hi, I have been doing a common lizard project and to add to my discussion i was hoping that someone might be able to tell me how far or large an area a common lizard will travel to find food and basking sites? i realise this will vary from site to site but i did mine on a typical heath dominated by purple moor grass. Also if anyone is interested i have done a comparison to see if the lizards preferred one material type over the other (Corrugated iron and roofing felt) but there seems to be no significant preference even though, with the help of data loggers, i have got some quite good comparisons in terms of the materials thermal properties. and finally,It would seem that the lizards seen basking and the lizards seen on my encounter surveys showed very different peaks in the temperatures at which they were active, perhaps suggesting that the ones seen on the encouter surveys were foraging after basking? has anyone else seen this difference in the activities... picked up by the different methods?
thanks Brent |

Posted: 19 Jan 2006 I think you've hit on something for which there is a lack of a lot of solid data. Beebee and Griffiths (2000) say that they range over 'considerable distances' and mention an ability to return 'home' after a displacement of up to 100 m from a colony focus and add 'presumably because thay know their way'.
