No special meaning, they simply rebranded after rebuilding the entire zoo.
The ruhr zoo (cause its in the ruhr area) was really old and just a mess.
Habitats wernt up to welfare standards, the buildings needed renovations, it was quite ugly, all that jazz, so the zoo decided to completly rebuild and rebrand the zoo, resulting in props the most modern zoo germanys with cohesive theming and not a single bad habitat all throughout.
Its actually quite the interesting story, as the zoo at first funded the renovation of the lion and spotted hyena habitats themselfs, which live in a connected habitat where they can be let into the others habitat for enritchment (ofcourse not at the same time). This first habitat was presented to investors who absolutly loved, it so with a backing of the city, local bank and multiple food concerns they set out to rebuild the zoo in 4 distinct themed areas, africa, alaska, asia and a petting zoo styled after a traditional farm.
Over the next 10 years, one after the other the thematic areas where opend, with the first open year in 2004 only displaying the petting zoo, lions, hyenas and a display for african domestics, alasca opening the next in 2005, africa in 2006 and asia in 2010.
This is an old zoo map from 2005 and its really interesting to compare.

Since then not much has changed from the big picture perspective, with the largest new addition being a penguin habitat in the africa section and otherwise mostly just a general reduction of animals kept in multispecies inclosures with fore example the zoos marabous, egyptian fruit bats and griffon vultures not being there anymore, but there was also a bunch of nice smaller additions, for example dwarf mongooses, prariedogs and lots of stuff in their tropical house. They also opend up a turtle garden with african spurred tortoises and a mix of pet terrapins that they adopted from local shelters.
Biggest dissapointment propaply would be the demolition of the binturong habitat, but is how it is.
But yeah theres a reason that this zoo has kept the title of best german zoo since its completion in 2010 and i really doubt that they will stop winning that title each year anytime soon.
