You always know better anyway don't you

I can fully understand how nuanced this subject is and of course not one size fits all however my focus is to encourage anyone who will listen to not just accept the zoo is the final and only answer but to exhaust all other avenues and if some form of captivity or semi captivity of wildlife then it must be preferred to do that in country of origin if possible.In our case (which I admit is a highly unusual one), in contrast to what you have said about the prevalence of hybridization and disease in animals in captivity / zoos our focal species are actually subject to far greater pressures from hybridization with Callithrix jacchus and Callithrix pencillata and disease outbreaks such as yellow fever in the wild. These in fact ARE the principal threats to the species in the wild.
So much so in fact that some form of ex-situ management (in zoos or otherwise) may be even required to prevent the genetic extinction of our species from hybridization with the invasive species that I have mentioned or metapopulations being literally wiped out by yellow fever. Regarding, the case of one of our two focal species, the buffy tufted marmoset (Callithrix aurita), we have so far found that the most genetically pure individuals are actually held ex-situ within zoos.
I am mentioning this specifically in the context of this debate because you have raised the issue of both disease and hybridization. I think our case here in Brazil clearly illustrates that it is far more nuanced a topic than you suggest it to be.
Thank you for your comment and yes i do mean from a animal welfare point. This is from my own experiences and knowledge of watching animals in zoos for many years and of course some of the latest research from people like Bob Jacobs of Colorado University .....Considering the poor enclosures 99% of animals in zoos it is not really surprising.Damian, am I correct if I say that with "sub standard" you mean insufficient from an animal welfare point of view?
If so, I'm (again) interested to hear from you on what metrics (behavioural, endocrinological, etc.) you base the assertion on that a substantial part, of not all, zoo animals suffer from living in a zoo.
Thank you for your comment. I have given the name of Amos Courage at Port Lympne to quite a few people who have asked for this research and not one has bothered to reach out. We spent a lot of time researching these points of hybrids disease and genetically bottle necked species and anyone who needs to learn more has that contact info.Quite a few people in this thread have asked you to cite at least some of the CE mammal species in European collections whose captive populations you suggest are mere hybrids, and thus far you haven't answered this question - it is somewhat difficult for the members of this site to disprove claims which are never actually expanded on by yourself when asked.
On a related note, you have also yet to acknowledge the point made by several people in this thread that the categories of "Extinct in the Wild", "Endangered" and "Threatened" also include species which are of conservation significance, not merely "Critically Endangered" - as such, the number of species in captivity requiring no conservation action is rather lower than the 95% cited interchangeably for CE and unthreatened species.
Anyhow, good to see this overall discussion going a bit more smoothly now.
In this category if they are not able to be re wilded then i would hold species only for there lifetime.Out of curiosity, what should be done with all the non-subspecific individuals in captivity? They can be lions as well as turquoise tanagers, both of them non rewildable am I right?
This is based on what is beginning to happen with some zoos around the world like Barcelona and a couple of zoos in France where they are being shut down or taken over with a focus on re wilding. Secondly thousands of people reach out to me and friends with a similar goal and shared goals. There is also rumblings in the political spectrum about the future of zoos. As i said it is just a headwind today but the movement is building. I know of at least two documentaries being made as well which will only add to the pressure and i have no doubt will unrest the listless public on this subject who will start to be more demanding of the results of zoos.Hope this helps and thank you for your interestCan you elaborate on this? What evidence is it based on? How will this ‘storm’ materialise? And what is it based on?
no but in your case almost certainlyYou always know better anyway don't you

And how exactly does the research of Bob Javobs proves anything about animal welfare? I fail to find a comparative study between wild and captive individuals. In general I fail to find much comparative studies between wild and captive individuals, and one about cetaceans that I found actually found lowered stress levels for captive animals compared to wild animals. Seen as the logical zero-hypothesis would be that animals in zoos would have equal stress levels as those in the wild, I'm very curious what studies you have found that actually disprove this zero-hypothesis in a negative way.Thank you for your comment and yes i do mean from a animal welfare point.

Barcelona intention is to re wild as many animals as possible according to the council that own it which is fantastic and we are aiming to help them achieve this Point Scorff and doing a very good job in a very difficult situation and again we are helping them in any way possible and although they had some earlier problems that are getting themselves organised.Sadly millions of people are completely mislead by zoos by the lies and myths but believe me that is changing and not to soon in my humble opinion. Thank you for your commentBarcelona continues to function as a zoo. Zoo de Pont-Scorff in France which was taken over by a group with an apparent focus on re-wilding is currently a complete shambles which is unable to take care of its animals. Thousands of people might reach out to you but millions go to zoos, recognise their worth and support their work.
If it's so easy to find his research, why can't I find no published studies from him about this subject?Thank you for your comment.

I did not say it was easy to find .. I said if you want to know how we came to our conclusions reach out to Amos Courage at Port Lympne who carried out this work for us ...If it's so easy to find his research, why can't I find no published studies from him about this subject?

It took me a few seconds to find this: https://www.researchgate.net/scientific-contributions/Amos-Courage-2009832524. I just keyed 'Amos Courage' into Google.If it's so easy to find his research, why can't I find no published studies from him about this subject?

I did found those studies yes, but they don't answer the question. You gave that name as an answer to hybrid animals in zoos and inbreeding/outbreeding depression in zoos, this doesn't prove anything of that.It took me a few seconds to find this: https://www.researchgate.net/scientific-contributions/Amos-Courage-2009832524. I just keyed 'Amos Courage' into Google.
If it's so obvious, then point out which study you believe to be so important. If you want to be taken serious you really have to be a little bit less vague. I did found some non-scientific articles about a lone elephant and a lone orka, but you can't seriously think that those are representative of the zoo population?Have you read it ? I think its pretty obvious
I can fully understand how nuanced this subject is and of course not one size fits all however my focus is to encourage anyone who will listen to not just accept the zoo is the final and only answer but to exhaust all other avenues and if some form of captivity or semi captivity of wildlife then it must be preferred to do that in country of origin if possible.
that's great but i was referring to the research he did on zoo collectionsIt took me a few seconds to find this: https://www.researchgate.net/scientific-contributions/Amos-Courage-2009832524. I just keyed 'Amos Courage' into Google.
Bob Jacobs study Heading ..the neural cruelty of captivity is a great start.If it's so obvious, then point out which study you believe to be so important.
