Animal News

Very recently, Hannover Zoo in Germany have opened their new 'Amphibium', a house dedicated to amphibians. It includes all sorts of interesting exhibit types for these animals - not only some very large tanks, but some that are at least partly open-topped, a view into the breeding tanks and, perhaps most interesting, a large walk-in greenhouse for tropical frogs. I'd love to have enough pieces to make something like this in the game.

A video about the construction of the house can be seen here:

It's such a great house, I definitely have to visit Hannover this year, it's been ages since I was there. The pictures and videos are so exciting.
Amphibians are still very underrepresented in zoos which is a pity as they are the most endangered class of vertebrates and we desperatley need more breeding programmes due to the chytrid fungus. Luckily there have been some progress regarding amphibian breeding programs in the last couple of years with more and more zoos participating. Still, we need way more exhibitions dedicated to amphibians in zoos, so I hope Hannover's Amphibium can be a role model for other zoos.
 
Just read through the annual report of 2023 of both Berlin zoos and there is one very, very interesting information about future developments that I want to share here.
I heard rumours before - or let's call it half offical information - but now it's official (and still a little unbelievable for me): Tierpark Berlin is going to build a gigantic new breeding complex for white rhinos but not for the Southern ones, they'll do it for the Northern ones!
Seems weird because the subspecies is functionally extinct (only two infertile females left) but for a few decades now the Leibniz Institute for Zoo and Wildlife Research (which site is located just next to the Tierpark) is working on bringing back this subspecies with the help of embryo transfer using Southern white rhino cows as surrogate mothers. The embyros are "produced" in the laboratory with sperm and egg cells they got from Nothern white rhinos when there were more specimens left, those were deep frozen for a time the technique is better (and this time apparently is now).
Last year or so they had a kind of success when successfully transplanting a first embryo into a female Southern white rhino cow in a Belgian zoo. Unfortunately there was an abort a few weeks or months into the pregnancy but the transfer itself worked and they apparently are very, very close to a complete breakthrough.
So, this new planned enclosure hopefully means we won't have to wait that long to see a new generation of Northern white rhinos on this planet.:love:
I guess they'll get some Southern white rhinos at first and those will be used as the surrogate mothers for the new Nothern white rhinos and then those will be the founders for a new Nothern white rhino population.
All in all very exciting news, I guess!
 
Here are some more information about the first successful embryo transfer: https://www.izw-berlin.de/en/press-...he-northern-white-rhinos-from-extinction.html
(I was a little bit wrong though, the white rhino cow used for the embryo transfer is one living in Kenya but the eggs came from a Belgian rhino and there was no abort but the female died being pregnant).
So, this first embryo transfer was done with a Southern white rhino embryo but the next step is attempting an embryo transfer with a Northern white rhino embryo.
This sentence by Prof Dr Hildebrand: "It comes just in time to achieve a pregnancy for northern white rhinos: we want the offspring to live together with Najin and Fatu for years to learn the social behaviour of its kind. Although embryos can be stored in liquid nitrogen for a very long time, we are in a rush to bring a northern white rhino baby to the ground – with this proof of concept it can become a reality in two to three years." :love:
That's so exciting!

😍 That's absolutely amazing. I hope this will work. So nice to see so much Stuff about bringing back extinct Animals recently (well, actually only that one and Colossal Bio Sciences, but before that, everything was only Text that you could read about past Experiments : Pyrenean Ibex, Gastric Brooding Frog. But this might work, not only because those Animals are closer to their Surrogates but also because there is probably new important Knowledge and technical Improvements nowadays)
 
Excellent news! The Iberian Lynx has improved from Endangered to Vulnerable on The IUCN Red List. The population has increased exponentially from 62 mature individuals in 2001 to 648 in 2022. Today, the total population, including young and mature lynx, is estimated to be more than 2,000.

Fantastic news! Thanks for sharing. I didn't know the population increased that much.
