Posso aggiungere qualcosa sulle yniphora...
Il furto ad Ampijoroa nel 1996 è stato grave ma non gravissimo: sono sparite 75 tartarughe, di cui 73 erano baby, e solo due le femmine adulte (sarebbe stato ben peggio il contrario, visto che questa specie impiega vent'anni a maturare). Circa la metà dei piccoli sono stati recuperati, ed il totale delle nascite (al 2004) era di 224.
Le prime 20 subadulte nate in cattività sono state messe in semi-libertà (recinti controllati e trasmettitori radio) nel 2005; l'obiettivo è di rilasciarne 80 in quattro anni.
Nell'Aprile del 2005 è stato aperto un nuovo villaggio a Mangily-Ifaty, sotto l'egida del SOPTOM di Devaux; oltre alle yniphora segue anche le Pyxus arachnoides.
Ciao
Thanks for informations, dear Alessandro. I am affraid, independing of new breeding station for G. yniphora in Mangily-Ifaty, situation will become worst from day to day, not better. The only right captive bred of this species, like in many others could provide safe future of it. No other solution available!
I will add some interesting photo in this discussion now, and independing they will appear very beautifull, I am not so satisfied in them, and by my point of view, this work could destroy endangered species, too. It is HYBRIDISATION in Tortoises!!!
Maybe, it is not right place to speak about it - there are two other discussion in this matter on Tarta Forum, i.e. T.H.B. albina, and copia of Sg. "Vinci" T. H.... On first discussions, we are speaking about color Mutations in Tortoises, and, as I can see, many participants in this disscusion are speaking very negatively about captive bred of color Mutations in Tortoises and Turtles?!
It is slightly strange to me, because I love color Mutations in Tortoises very much, both natural and artifficial, i.e. captive born. They are also God's product and God's gemms, and they are existing because God like to do it. So, because born, they should survive, and breeders should take enough care in them. Due to their rarity, they become much expensive, but where is problem in it?
Many different animals species survived in the wild, due to their great potential to give various color Mutations. It is 100% truth!!! As you know very well, there is big quantity of different color Mutations in Ring-necked Parakeets (Psittacula krameri), Alexandrine Parakeets (Psittacula eupatria), all Australian Parakeets (Rosellas species, Red-rumped Parakeets, Neophemas), and newly in Galah Cockatoos (Eolophur roseicapillus), too, as well in Indian Blue Peacock (Pavo cristatus), Golden Pheasant (Chrysolophus pictus), etc.., etc... All of above mentioned are abundant in the wild, due nobody is having interest to buy wild catched specimens in their natural color. There are many different color Mutations available by breeders, and people are interesting to buy some new colors for their own bred, to work in genetics of new colors, etc..., etc... And, we cannot treat these people as idiots and ignorants. They are working nothing bad against nature, and nothing bad agains species with high Mutations potential available. No, they are increasing number of specimens of each species like this significatory, many new breeders are appearing each year, etc....
To me, much bigger problem is hybridization between different species, or different subspecies of the same species. It could be very big problem, and it is having very negative implication to nature surely. As example, I am near to be sure, it is very difficult to find right Italian Pernice Rossa (Alectoris rufa) in Italy, due to their hybridization with French or Spain subspecies of it. The same could be with Italian Starna (Perdix perdix) and many other species worldwide.
So, making hybridization with different subspecies of Hermann's Tortoises, we will have not very soon right Hermann's subspecies available, and we will lost knowledge about them. The same is with hybridization of T. graeca subspecies (there are so many of them), Marginated T. subspecies, Russian T. subspecies, etc..., etc...
I do not know why people are doing this, but it is surely unnecessary, and totaly wrong. It could be interesting maybe (as well as matting of domestic Fowl by Guinea Fowl as example), but what is value of final result!? What we will receive? Who is interesting to have it as his pet animals, favorite animals or breeding animals!?
Anyway, the people do not love natural products as color Mutations in live animals species, but - they love to crossing them each other.
Yes, products could appear very beautifull, but anyway - UNVALUABLE!!! Check the attached photos, please:

It will not help survival of G. yniphora surely, and give nothing positively to G. radiata, too!
