Alternately, Nearctic, Neotropical, Palearctic, Paleotropical (Afrotropical + Indomalayan), Indopacific (Australasian + Oceanian), and Antarctic.

I’ve binged watched videos about this, and have always wanted to make a video about it. You nailed it

Thank you, Pranav! It's a very interesting topic, and there is always room for more coverage of topics. I still have more to learn about this too. So please bring your unique perspective to this topic! Thanks for watching again this week!

Really great showcase of the eight biogeographical regions, the floral kingdoms are another interesting way of breaking up biology, I think New Zealand is in the Antarctic Floral kingdom, and southern africa is its own thing. Best JJ

Thank you, JJ! I'm always happy when a video gets your stamp of approval. It was interesting to see the different ways that people have tried to put natural systems into categories. This one seemed logical. There are probably a million edge cases that drive biogeographers crazy. Thanks for watching!

Thank you this has helped me gain a better understanding of the realms for my assignment

Hi Bethany! I'm glad you found this helpful. There is so much out there to learn! Thanks for watching!

You are such a great explainer. Thanks for the effort you put into your content.

Thank you, Rafael! I was so happy to find out my crazy animal observation had some theoretical support. I appreciate you taking the time to learn!

Thank you for the kind words, Nitish! There are so many interesting things to learn about birds, and the world in general. Thanks for watching!

Technically, the Grizzly hasn’t been isolated for long enough to split from Palearctic populations of Brown Bears; therefore, they are still the same species. Since the Palearctic and Nearctic have regularly been connected together throughout the Cenozoic, some species (Gray Wolf, Brown Bear, Red Fox, Moose, Caribou, Northern Pike) are the same in both realms, and others have only recently diverged (Red Deer and Elk, European and American Bison, Eurasian and Canada Lynx, etc.) In the case of flighted birds, more species are shared than with, say, mammals, due to their higher mobility: Red Crossbill, Pine Grosbeak, Common Raven, Golden Eagle, Northern Goshawk, Green-winged Teal, Mallard, Greater Scaup, etc. However, there are even more unique species on either side, creating a new mystery. Perhaps this is for the same reason there are more bird species than mammals, but more research needs to be done.

Hi Vernon! What an interesting observation! If birds could thrive in either realm, and they can freely move between the two, why have the majority of birds not made that movement? You're right, more research *is* needed. I also noticed the Grizzly Bear thing late in editing, so I put a subliminal correction at 1:34. :)

If I ask it is zoogeotrphical realms or only geographical realms because somewhere I read there are six zoogeographical realms

Hi Smruti! That's These are the biogeographic realms as defined by Miklos Udvardy. Many different people have worked on zoogeographic realms and most have defined six of those. The six zoogeographic realms are broadly similar, just drop the Antarctic and Oceanian realms. I've been thinking about Udvardy's scheme so much that it feels weird to leave them out, but I can see the reasons for each. Antarctica's animals could probably all be defined as marine species, and Oceanian species are descended from one of the other realms. For me, the eight realms make more sense, but it's interesting to learn about the differences between classification schemes. Thanks for watching again this week!

we could have had 9 like in Norse mythology, we were so close to greatness!

Hi Marco! Maybe we can add one, like species on the moon, to get the full 9! Species would have very different growth there. And having a space realm would be pretty great. There are also 23 saltwater biogeographic realms. The barriers of continents and temperature are much more profound in the ocean, so there are more isolated pockets. Thanks for watching again this week!

Some ecologists have suggested splitting Madagascar from the Afrotropic, splitting Central America from the Neotropic (as the Panamanian), splitting Japan and much of China from the Palearctic (as the Sino-Japanese), and splitting North Africa and the Middle East from the Afrotropic and Palearctic (as the Saharo-Arabian).

I may be dumb but shouldn't Madagascar be it's own realm?

@BioBush

Hi Matthias! I have been thinking about your comment for a while, and agree that Madagascar qualifies in every way. It has been separated geographically for ~90 million years and has unique, endemic plants and animals as a result. *Maybe* the reason it's lumped together is because Madagascar's evolutionary history is a sample of Africa's evolutionary history? But the Oceanian realm is the same situation, being a sample of species from other realms. I don't actually know the reason why Madagascar (or New Zealand, the Galapagos, etc.) are not separate realms. There is more to learn on this subject! Thanks for watching again this week!

@@BioBush watching is always a pleasure..also Europa, and asia could been spilt apart and maybe even those two could be split in to smaller realms maybe we should make sub-realm...like shara has totally different animals depending on if there is coast and or water... example nile crodile in Egypt...but this may be a discussion like how many continents are there , and should pluto become a planet again? (I my opinion pluto is a planet and the voteing on was not scientific at all )

Before you make your next video, I need to make sure you understood Ecotasia’s “Does Biodiversity Matter” video. What do you think about biodiversity? Is the term useful? Tell me your thoughts.

Hi Vernon! I thought about your comment for a while. My comment on that video sums up, "I think there are going to be pros and cons of each environmental philosophy." I have an idea on how to demonstrate the ecosystem stability argument. Thanks for bringing up the video, because it would be interesting to bring that into the mix of ideas. Thanks for watching, Vernon!

I have a bird that’s heart could you make a video how to help birds it’s a black little bird a black beck and it’s just a baby

Hi Darryl! I'm so glad you want to take care of this little bird! The #1 thing to do is watch if the parents are taking care of it. #2 is try to get it back in its nest. #3 is call a licensed wildlife rehabilitator in your area. Unfortunately, raising baby birds at home almost never goes well for the bird. I'll put all this in a video someday, but that's the quick answer for your situation. Best of luck as you try to help this bird!
