My Dear Richard,

Firstly, you have a very strange definition of the term "myth". For what it is worth, almost 20 years of field and laboratory studies, fully repeatable, backed up by sound biology, reinforced by hundreds of clininal case studies seems to me to be stretching the terms somewhat!

Precisely why and how protein levels in food result in pyramiding are extremely straightforward to comprehend, and you can indeed repeat the experiments yourself. You are correct in stating that some aspects of the biological interractions are quite complex - but this is, I fear, what has led your conclusions astray. You simply do not seem to understand what is really going on in terms of the nutrition/environment interface.

I shall expound shortly at some length to shed a bit more light on this, as it is plainly confusing to many...

However, before I do so, perhaps I could request your forbearance in explaining the following:-

1. One population of T. g. graeca in S. Morocco. 30% of the population live in the Opuntia hedgerows next to planted fields of French beans and Alfalfa. All of these tortoises have classic "pryamiding" with evidence of very high growth rates and lumpy shells. The remaining tortoises live in uncultivated field borders and exhibit normal growth. You explanation, please?

2. What is the mechanism/link between a) Temperature and growth b) Humidity/Hydration status and growth?

As you seem so determined to "prove" that I'm wrong, the least you can do is enlighten me as to why you think you are right! .

Regards,
