The Best Biome

In this month's Best Biome, Nicole tells the story of a grassland ecosystem so rare and so endangered that neither of her co-hosts had any idea it existed! We're talking about the once-ubiquitous canebrake ecosystems of the eastern United States, which were quite literally American bamboo forests, complete with their own prehistoric red pandas. Find out what happened to the unique rivercane landscape, and what's being done to save ...

Our view of nature is often constrained by the idea of competition: life as a zero-sum game, where the victorious survive, and the defeated fade into extinction. But not every relationship in life is competitive! Sure, as living things, we must always be aware of our enemies, but our survival is just as closely tied to our social entanglements- our family, friends, neighbors, and communities.

In a rebuttal to the hyper-competitive ...

Phytoremediation. A fun word to say, but what does it mean? Turns out it's quite simple: using the superpower many plants naturally have to heal our wonderful Earth from terrible soil contaminants. Allan pulls us off the dark abyss edge that is our current world to deliver a wonderful tale of plants.

The Best Biome finally reps reptiles properly as Nicole tells us all about an enormous lizard of the South American grasslands. Buckle up for voracious appetites, raging hormones, and an unexpected peek into the evolution of endothermy. This is: the world's hottest reptile.

This month on The Best Biome, Rachel takes us on a trip to the wetter, saltier cousin of grasslands: seagrass meadows! Is she making a desperate reach to connect the dots, or is she absolutely right that "seagrass meadows are the grasslands of the oceans?" Decide for yourself, dear listener, and get ready to think more about seaweed than you have in a while. Plus, there's manatees! A very special episode awaits.

The grasslands of Japan are beautiful, full of volcanos, and revered by the people living there. Japan's unique model of conservation method of Satoyamas is one we wish the US would model - one where people push to thrive alongside the environment, not claim or set it aside. Allan hosts this episode and the five minute math break in the middle has been severely shortened (though stick around past the credits for a bit more).

In the final episode of the season for The Best Biome we lay out some concerns we have for the conservation of our beloved grasslands under a second term of the Trump administration. It's a hard discussion, but one we felt we needed to have. And boy was it a long one. If you don't feel up to listening now, we understand, though we still recommend you check out the action items at the end (see timestamps below to skip there). Much ...

A big animal can make big changes in their environment... and cause big problems for the people who live alongside it. African Elephants have a fascinating relationship to the savanna and the people who call it home, where it is equal parts feared and revered. The world of elephant conservation is complicated, and in this episode, Nicole examines the nuanced stories of these beautiful beasts and the conflicts that surround them.

Happy Halloween from your grasslands PR Team! This month, Rachel confronts one of her worst childhood fears to bring us a tale of the strange and slithering: a group of animals so odd and cryptic that the existence of many species was only confirmed after their habitat was bulldozed. We're delving into the fascinating world of worm lizards, a world full of unknowns that still begs to be explored. After all, how can we learn about ...

Possibly the best episode of all time (according to me, Rachel). Allan gives us EVERYTHING. Great science, high quality takes, crying with laughter, investigative reporting and red string conspiracy boards. To what end?? Drafting porcupines, well-known "tree-lovers," into the Best Biome (grasslands). Potentially. Hear us out!

Bees know more than you. Okay, that may be a slight exaggeration, but they definitely know more than you realize! From complex problem solving to tool use to wing-sparkle navigation, bees illuminate our understanding of insect cognition. In this episode, Nicole invites us to perceive the world as our buzzy, bumbly friends might, in beautifully smooth 240 fps.

Desertification is a major threat to many grasslands, so let's study the best real-world example: The Horqin Grassland, aka the Horqin Sandy Lands. How has this landscape changed over time, what can it teach us about the future of arid grasslands, and which approaches by Inner Mongolia and China to fight desertification give us hope? We love a hopeful story, and this certainly is one.

We get patriotic (kinda) in this special episode where all three hosts work together to petition for new national symbols for the US of A. New floral emblem, new national symbol, and a brand new category all-together. Why do we love non-native national symbols? Who knows. Do better, America.

The fastest land animal in North America, second fastest in the world: the graceful, wonderful, pronghorn. Nicole shares all the reasons these icons of the American prairie are truly the best from their evolutionary history to their epic stare battles between each other and rump flashes to warn of predators.

The conservation story of Canada's polar-vortex-loving Wood Bison is one of colossal mistakes, stacked odds, and (to our gleeful surprise) hope and optimism. These animals have survived drowning, disease, and hybridization, and have gone on to... success? Allan explores this topic in today's episode.

It's snowy and getting colder where we're at, but that doesn't mean you shouldn't go outside. Rachel gives a compelling argument as to why winter is the best time of year for birding and gives insight into the Christmas Bird Count: a citizen science project dating back over a hundred years.
