The BIOGEOGRAPHY of the Ice Age

During the Ice Age, not only was the landscape of the Earth drastically different from what it is today, but so were the animals you'd find walking along side our ancestors. Just a few thousand years ago the world was filled with megafauna, or giant animals, and every continent held a collection of unique species unlike anything that remains alive in modern times.
Join me as I take us through some of the fascinating biogeography of the most recent Ice Age!

    Sebastian Martinez in addition, the land in the Southern Hemisphere is much closer to the equator than the land in the northern hemisphere. The southern tip of S America is only 56 degrees below the equator, whereas 56 degrees north is still below much of Siberia and Canada. And, as he mentions in the video, equatorial regions were relatively unchanged.

    First of all, Europe's glacial refuges were much smaller. Compare the landmass of Iberia, Italy and the Southern Balkans plus Anatolia and the Caucasus (Western Palearctic, belongs to the European biogeogrphical region) to Southern China, India and South-East Asia. Plus Iberia, Italy and the Balkans would have all been isolated due to glacial ice sheets in the Pyrenees, Alps and the Dinaric mountains. Smaller refuges means smaller population sizes, smaller population sizes means increased vulnerbility to e.g. human hunting. And then even in South Asia with its extensive habitat for megafauna Stegodon (a browsing proboscid), Plaeoloxodon namadicus (a huge elephant), Palaeoloxodon naumanni (Japanese elephant), a giant tapir, several water buffalos, Hexaprotodon (basically a hippo) and more went extinct.

    As Nero Bernardino said, the ozone layer is usually in some kind of equilibrium. Whatever dissipates or vanishes through natural processes, gets also replenished through natural processes. We disrupted this equilibrium with the large-scale production and release of chlorofluorocarbons (hydrocarbons with chlorine and/or fluorine atoms) into the atmosphere. They were used as aerosols (i.e. the gases in spraying cans etc.), in refrigerating, and as solvents. These chemicals also react with ozone in the upper atmosphere and bind the ozone, thereby depleting the ozone layer. Starting in the late 70s, and esp. with the Montreal Protocol in 1987, the countries of the world agreed to severely reduce the use of chlorofluorocarbons, and today, we nearly stopped using them. Therefore, the ozone layer started to return to its normal state, slowly closing the gap.

    They were not very destructive though. On a big scale invention of oxygenic photosynthesis increased organic matter production many times compared with earlier chemosynthesis and anoxygenic photosynthesis. Biodiversity and amount of matter and energy available to biosphere as a result increased. Also, oxygenation of atmosphere happened very slowly, over the millions of years, and microorganisms can reproduce and evolve really fast, so I doubt many huge taxa died out, there were probably more than enough species in every big taxon to either adapt to oxygen, or find anaerobic niche. Most bacterial and archeal phyla diverged before the oxygenation, and they (many many of them we still see today) still survived. If most phyla died out during oxygenation, we would see "bottleneck" - only few phyla diverging before oxygenation, and most diverging after it from only few taxa, which survived the event

It can also help understand how a big change over a small time can have large effects that are difficult, and most likely impossible, to reverse. Climate change and loss of biodiversity will surely have massive effects and someone might even be able to make a video like this in just 100 years looking back at how insanely different the world was in just 1800.

    It likely wasn't. The reality is that the areas with the least decline in megafauna are the areas where the climate changed the least, and the areas where the climate changed the most suffered the greatest losses. South America's vast taiga plains turned into a rainforest, Eurasia and North America radically rearranged there biospheres as the vast sheets of ice retreated. Even when we look at Australia, likely half of the forested area of the ancient continent is under water today. In contrast, Africa's deserts are still in basically the same places, Indomalasia's rainforests are still in basically the same places (except where we've chopped them down). Grasslands & forests have shrunk or grown, but are still in basically the same places.

Most domesticated plants and animals would have a terrible time if humans went extinct. That said, I think you’re still right about being cozier with humans makes animals more successful, especially for pests and weeds. I expect rats, Argentine ants, and tumbleweeds would do just as well if we went extinct right now.

    That would explain the event if the Weichselian transition (the last major climate change that ended the last Ice Age and started the current Holocene) was a one-off event. Unfortunately this is far from reality. During the whole Quaternary (Pleistocene + Holocene) the earth experienced as many as 8 such climate changes, i.e. prolonged Ice Ages periodically interrupted by warm interglacial periods, yet the effects on the megafauna were negligible in that they didn't cause nearly as much interuption and didn't produce megafaunal mass extinctions. Actually, the last of these interglacials (that is to say the last before the current Holocene), the Eem interglacial roughly 130.000 years ago, was both longer and warmer than the current Holocene, yet the mammoth-steppe fauna survived throughout without trouble. Similarly, temperate faunal assemblages such as the European Palaeoloxodon-fauna (straight-tusked elephant, two Rhinocerus-species, deer etc.) respectively its ecological predecessors (southern mammoth and different rhino-species) survived throughout all glacial peaks, some of which were more pronounced than the last one that coinceded with the extinction of for instance the straight-tusked elephants, without trouble, even though they were restricted to small refuges. This is a major flaw in the climate-change argument, and I don't see it being adequately adressed by those who claim the climate did the megafauna in.

I read - can't quite recall where - that for a time the first humans and megafauna from Eurasia to make it into North America were actually trapped in Beringia/Alaska as the steppes had fully retreated from mainland Eurasia before the glaciers had opened up enough in Alaska for them to make their way into the rest of North America.

This is why you have the existence of Dwarf mammoths along the islands near Siberia and Alaska. Also, I read somewhere that while there were a few waves of humans that colonized the Americas, the Native Americans of today came from possibly just one core group of maybe 10,000 Ancient Beringian people that crossed over 20,000 years ago. The lineage does exists in Siberia but seperates from native Americas 17,000 years ago. Seems at some point when humans existed in the area there was a short lived "decent" land bridge, but its was probably not as lush and inviting as it may have been during that pre-human time when animals moving back and forth between the two continents. I think if the land bridge was more lush and long lasting you would have more human diversity in the Americans.

They went south from Alaska before going east.

    That makes more sense. You know how small the human population was back then? No way people back then with stone spears extinct animals. The land mass to population ratio , would cause many animals to live without even seeing a human once. Killing big animals with $3000 carbon fiber crossbow is very hard let alone a stone tip spear. "Grab the spear son we are off the extinct the 1000lb cave bears and tigers and chase down the horses and mammoths." WTF?

    You mean the impact event that happened long after the megafaunal extinctions in Australia, Asia, and Europe already happened? Also, humans of that time had bows, blow-darts, serrated throwing spears & knives, fire, and quite possibly dogs (depending on whether you trust the genetic or archeological dates nore).

In fact, there is plenty of sunlight available in the growing season (summer) as it is polar day at this time. Plus, tundra vegetation includes lichens, grasses and shrubs and not limited by mosses (see Circumpolar Arctic Vegetation Map). Perhaps, you meant polar desert (it also includes lichens)?

    @@XavionofThera That's simply not right by definition and current understanding. Just know that glaciations as a whole are considered ice ages. Likewise, glacial and interglacial periods are part of the glaciation. The known 4 major Ice ages lasted for several hundred million years. Glacial and interglacial periods last 40 to 100 thousand years. A glacial period itself is not an ice age. The ice age we are currently experiencing is the pliocene-quaternary glaciation and it "just" started a mere 2,5 million years ago (which is minuscule in terms of ice age periods). I'll just leave you with a copypaste and the link to an article which explains it rather well. "What is an Ice Age? Scientists have known for some time that the Earth goes through cycles of climatic change. Owing to changes in Earth’s orbit, geological factors, and/or changes in Solar output, Earth occasionally experiences significant reductions in its surface and atmospheric temperatures. This results in long-term periods of glaciation, or what is more colloquially known as an “ice age”. These periods are characterized by the growth and expansion of ice sheets across the Earth’s surface, which occurs every few million years. By definition we are still in the last great ice age - which began during the late Pliocene epoch (ca. 2.58 million years ago) - and are currently in an interglacial period, characterized by the retreat of glaciers." www.universetoday.com/74714/what-is-an-ice-age/ Nice username by the way, made me chuckle.

    In my opinion, this is why we should try and restore the ice age “mammoth steppe” biome, by restoring this habitat we can introduce animals that survived the ice age (Bison, Musk ox, wild horses) and make a habitat suitable for them again. In the far distant future we may even de-extinct mammoths or woolly rhinos and have them roaming the far north once again.

    1. It wasn't a coincidence that the Panama land bridge coincided with the onset of the ice age -- it halted a warm current from the Caribbean up the west side of North America, thus triggering the ice age. 2. It was mathematically impossible for humans to kill all those megafauna in such a short period of time. The Younger Dryas catastrophe was the more likely culprit.
