Even MORE Islands That Aren't Islands

Today we take another look at isolated environments to learn how islands can arise even when surrounded by vast seas of desert!

Here are the sources and further reading for the Dhofar Mountains section of the video, they didn't all fit in the description:

Common AtlasPro W. Never would have guessed Antarctica had its own species or so many of them. Keep up the great work 💪

Another "Island" that might interest you would be Lake Hévíz in Hungary.
It is a Thermal Lake that runs off in a warm stream, therefore creating an "Island" of unique plants and animals that
live in the year round warm waters. I'm pretty sure other thermal streams and lakes around the world create similar "Islands".

Not only is the tip of Baja California a biogeographic island, but it was also a linguistic island in the pre-Columbian era. The area discussed in the video was inhabited by a people called the Pericú, and their language appears to have been a language isolate, that is, a language with no known relatives. That means that the Pericú language can be considered endemic to the tip of Baja California. Besides the Pericú, several other Indigenous languages were spoken in the southernmost third of Baja California, including Guaycura/Waykuri and Monqui. Since the languages of central and northern Baja are known to belong to the Yuman family, which extends into California and Arizona, the southern third of Baja California can be considered a linguistic island in the anthropological geography of North America.

i don't know if you consider that as an oasis but in the south of greenland in a valley there is a remainder of what used to be greenlandic forests. We found this forest in the Qinngua Valley if you want to look at it

📍 Submarine groundwater discharges are understudied. There are a few underwater oasis of freshwater that have endemic brackish species.

In my home country Mozambique, there is a bird called Black-headed Apalis, the species can be found in some specific areas throughout the country, in lowland and riverine forests. The interesting fact is that a subspecies of the bird (as of now it has not been published yet) lies in a small forestry area close to the ocean in Inharrime ( specifically the forest occupied by the lodge Dunes de Dovela). It differs from the original species, in color, while the normal has pinkish legs and white eyes, this one has red legs and red eyes. I was lucky to have been able to spot it a few times during my time there. The forest there is full of birds ! It would be interesting to understand what makes that small location a haven for life to thrive in!

This man is insanely passionate about geography and I love it. He's making the kind of stuff that I would have gone mad for as a teenager. I used to spend hours looking through atlases and would wonder about all the little details I was seeing. Then I would do the same when I got my first internet connection - spending ages on a website showing aerial and satellite photographs of the world, called TerraServer, before Google Maps existed. To see a regular person making high-quality videos about all these places, with facts and footage included, is just beyond cool! Thank you for all your great work. Please keep it up - it's a breath of fresh air!

Three Australian examples I can think of:
1. The Antartic Beech or Nothofagus Moorei - a Gondwanic reminant that clings to the highest peaks of the Lamington Platau, Lamington National Park and Mount Barney National Park, where the climate is still cool and moist enough for them to survive, as the Australian contenent slowly drifts further north.
2. The King's Fern, with fronds 2-3 m long, that grows in the cool damp conditions in Ward's Canyan - A side canyan of Carnarvon George, Carnarvon George National Park, in semi arid centeral Queensland.
3. The Wollemi Pine, a recently discovered living dinosaur! Found in a remote canyan in Wollemi National Park, NW on Sydney. This tree was previously only known of from its fossels.

Thanks Sadiq for inspiring this video!

This channel has such a good niche topic. It’s always very well researched, scripted, and edited. Excited for what’s next

If you need more isolates to explore, you should look into ecosystem on the abyssal plane, like Foodfalls, Brine Pools, and Hydrothermal vents!

📍 Devils Hole Pupfish (Cyprinodon diabolis). This species is endemic to Devils Hole, a geothermal water-filled cavern located in Death Valley National Park. The Devils Hole Pupfish is considered one of the rarest fish species in the world due to its extremely limited habitat and population size.

The Sierra de Laguna could be influenced by being an actual island a long time ago. Differences would be sustained by it's continued isolation, but could it be that species are instead becoming closer to other populations, as mixing is more likely?

Greetings From Mexico, in Ensenada Baja California,

Ideas like this, new kinds of islands, bring about questions. Where I live, my home, is within a deep rain shadow and creates a near desert where I live. Where on the other side of the mountains is a rain forest.
Literally where I live endemic life likely exists but it's normal for me.
Makes my small world seem bigger is my point. (Thank you for opening my mind.)

Oh wow, oasis in Antartica is quite unexpected

[SirFloofy]

And so my favorite biology/geology saga continues. Also Sadiq, love the isolates idea.

Mannnn, you need to upload videos more often - this satisfies the inner geography nerd within me more than any other channel on YT, you actually do some solid research and probe such interesting topics of special interest compared to everyone else. Great work as always
