While doing research for an upcoming blog post, I was reading a paper about how megafauna may have reduced woody cover in South America during the Pleistocene, and how today’s dry forest there could more closely resemble savannah if they were still around1. That gave me an interesting thought-there’s a lot of dry seasonal forest […]
There are few places on the planet as distinctive as Australia. With its isolated geographical location and iconic landscapes, it captures the imagination of people the world over. Picturesque red deserts, glistening beaches, and Eucalyptus woodlands may provide its most characteristic scenery, but arcane rainforests, snow-covered mountains, and much more can be found on the

The world was a very different place during the height of last ice age-known as the Last Glacial Maximum(LGM)-with very different climates, landscapes, and floral and faunal distributions compared to our current epoch, the Holocene. The exact chronology of this period varies according to the source but it is generally considered to be the point

They were a group of big-game hunters with distinctive hunting tools that allegedly bypassed formidable glaciers through an inland ice-free
If you’re well-versed in Pleistocene ecology, you’ve almost certainly heard about the steppe-tundra, also known as the mammoth steppe. During the Last Glacial Period, this biome covered vast parts of three continents: Europe, Asia, and North America. The name “steppe-tundra” refers to the fact that it contained a unique mixture of steppe and tundra species,
