I see what you are getting at, but I don’t think it is that straight forward.More to this point...don’t veiled chameleons only survive for one season, maybe two in the wild? Well in captivity, even in an outdoor enclosure we’ve removed pretty much all natural causes of death, stress, and most disease. Maybe they are naturally less robust after around a year or so of age? It’s very interesting we can keep them “healthy” for 8 or more years in captivity, but are these goals realistic? Maybe optimal wild conditions aren’t optimal for longevity? Just food for thought.
For one in the wild there are a multitude of micro and macro environments to choose, so they would go where is best for them.
As for them dying at one or two seasons, is not due to their weakness. If you look at satellite imagery of the area. Yarim to Ibb is the area too look at. During the dry season there is nothing, very bare and exposed. Also at this time other predictors are hungry because much of their pray is gone. This coupled with the lack of insects at that time of year, means you better be able too maximize the good times if you hope to survive.
In fact only the ones that are best adapted to maximize their short time propagate.
Many animals we keep are like this, especially some fish. They have short wild lifespans, but can live long in captivity. This is because they are seasonal. But if kept in the right season they can live long.
All animals will be extremely adapted for their environment, they have to be. Life is too hard in the wild already.
