2024 is going to be another year of the cicada, with the emergence of two periodical cicada groups, or broods (Brood XIII and Brood XIX), at the same time, roughly in late April to early May.

Now, throughout much of the world, cicadas serenade us in summer afternoons - you might be familiar with that, and wonder “what’s the big deal”.

But in a few special locations, periodical cicadas emerge on a specific cycle, every 13 or 17 years. These emergences are like clockwork - somehow these insects know exactly when to emerge from the ground, in synchrony with each other, across a vast geography.

But it gets better still. Multiple species of cicada emerge together, sometimes in massive numbers approaching 1.5 million per acre of land.

And weirder still, these same species might emerge on a totally different schedule, offset by years, in areas a few hundred miles away.

What’s going on here? Well, this is just the start when it comes to the amazing aspects of cicadas. And today’s guest, Dr. Chris Simon, is perhaps the world’s expert on Cicadas. She joined me for an incredible wide-ranging discussion all the way from New Zealand.

Dr. Simon has been studying cicadas for decades. She is a Professor in the Department of Ecology and Evolutionary Biology, and has a list of accolades so long that I could spend several minutes reading them.

So get ready to learn why these broods of cicadas emerge as they do, how glaciation influenced their locations, why 13 year cicadas tend to occur further south than 17 year cicadas, and of course, how you can see them too.

You can find more about Dr. Simon at cicadas.uconn.edu. And if you are interested in helping contribute to research on cicadas, download the cicada safari app from Apple or Google. More on that in the episode.

When it comes to understanding nature, it often seems like the ocean surface - that undulating reflective layer of water - is more like an impenetrable curtain than just a layer of water.

There is just so much we don’t know about, and are too quick to dismiss, all because we can’t easily observe what’s going on down there.

Thankfully, octopuses are having a renaissance in popular culture, and as a result, serve as sort of an ambassador to the oceans. And this is in no small part due to the efforts of my guests today, Sy Montgomery and Warren Carlyle.

Sy Montgomery is the author of Soul of the Octopus and Secrets of the Octopus, among her many works.

And Warren Carlyle is the founder of OctoNation, a nonprofit octopus fan club boasting over a million members, and they have information on and photos and videos of nearly every octopus species on Earth.

Today we discuss just how incredible octopuses - and I admit, standard words like amazing and incredible just seem to fall short when describing these creatures.

They can contort and fit through tiny holes, change their color and texture in the blink of an eye, they can reason, some can use tools, and they are incredibly strong. They range in size from a kernel of corn to 300 pounds.

We cover a range of topics, but we delve deepest into exploring their intelligence. This, coupled with their distinctive lifestyle, physiology, and abilities, often leaves us humans astounded.

Sy and Warren had a new book, Secrets of the Octopus, released on March 19 2024, and are contributing to an exciting three part National Geographic TV series coming out on Earth Day 2024.

You can find Sy at symontgomery.com, and check out Warren’s efforts at octonation.com and @octonation on most social media platforms.

Get ready for a jaw-dropping and mind bending discussion about octopuses with Sy Montgomery and Warren Carlyle.

My guest today is Dr. Rae Wynn-Grant. Dr. Wynn-Grant is the co-host of Mutual of Omaha’s Wild Kingdom, is a wildlife ecologist and affiliated researcher at the UC Santa Barbara Bren School of Environmental and Science Management.

She’s also an author, with her new memoir entitled “Wild Life” coming out on April 2.

Today we discuss Dr. Wynn-Grant’s unique and inspiring personal journey into wildlife ecology, her awakening to the world of environmental justice, triggered by Hurricane Katrina, as well as some of her active research pursuits, including her work with bears and mountain lions that seem to have a propensity for visiting the beach.

I really enjoyed both the book and the conversation today, because Dr. Wynn-Grant has so many facets of her story that I can relate to, and that I find inspiring, and I think you will too.

Find Dr. Wynn-Grant on Instagram, Facebook, TikTok, or her website.

Have you ever seen a fuzzy looking ant? Maybe it looked like a little pipe cleaner with fuzzy red or yellow hair?

If so, you probably saw a velvet ant. And here’s the thing - it’s not even an ant at all. They’re wingless wasps, and they often turn up along hiking trails, roadsides, and sometimes even in your backyard! And if you haven’t seen one, hit pause and check out the show notes on naturesarchive.com for a few photos.

What’s more, these wasps have quite the reputation and an amazing natural history.

With me today is Dr. Joseph Wilson, an evolutionary ecologist and associate professor of biology at Utah State University. Dr. Wilson is also the co-author of the new book, Velvet Ants of North America, as well as the wildly popular The Bees in Your Backyard.

I reached out to Dr. Wilson because I’ve always been fascinated with velvet ants, but found precious little information about them. I purchased the book and reached out to Dr. Wilson, and he graciously agreed to share some of his knowledge.

For example, did you know that some velvet ants have an auditory warning? And half of velvet ants are nocturnal? We discuss why we seem to usually see velvet ants deterministically wandering near trails, why they are often - and inaccurately - called cow killers, and more.

But I couldn’t have a chat with Dr. Wilson and not talk bees, so we kick things off with some discussion of bees, buzz pollination and more before transitioning to velvet ants.

Find Dr. Wilson on The Bees in Your Backyard, Facebook, Instagram, and Twitter.

In nature, tree physiology is like the engine that keeps forests running smoothly, similar to how human physiology keeps our bodies going. Just as we study how our bodies' metabolism, respiratory systems, and other systems work to keep us healthy, biologists can look at tree physiology to understand how trees grow, use energy, and cope with challenges in their environment.

Today’s guest, Dr. Lucy Kerhoulas, is an Associate Professor of Forest Ecophysiology at Cal-Poly Humboldt. She specializes in the forest physiology of northwestern California, which includes redwoods, Douglas fir, oaks, and more.

Today Dr. Kerhoulas explores various aspects of forest physiology including how they  adapt to different conditions such as fire and drought. She delves into the scientific tools used to study how trees respond to environmental changes, including measuring carbon isotopes in tree tissues to assess impacts of drought. And this understanding of carbon isotope preferences provides interesting insights into historical atmospheric carbon levels, dating back hundreds of years. In fact, this is sometimes called “the smoking gun”, because it provides strong evidence of fossil fuel contributions to atmospheric carbon.

Dr. Kerhoulas also discusses how trees can share resources and signal each other during times of stress, possibly creating a cooperative environment within a forest.

This was a jam-packed discussion, and I hope you enjoy it.

You’re in for a treat today - it’s like two episodes in one.

My guest today is Allasandra Valdez, a botanist working on her PhD in plant physiology in  Cornell University’s Ecology and Evolutionary Biology department. Allasandra also has a background studying invasive species, and is the creator and host of The Happy Botanist podcast.

Today’s wide-ranging discussion touches on everything from studying plants' response to climate change through looking at carbon 13 isotopes, to invasive species including the Hemlock wooly adelgid, to the surprising behaviors of an invasive grass called Johnson Grass.

We also discuss Allasandra’s work in science communication and her podcast, The Happy Botanist.

As you know, my Jumpstart Nature organization seeks to amplify great work being done by others, and after meeting Allasandra and learning about her work and her vision, I felt that she fit the bill. So the last 30 minutes or so of today’s episode is a re-share of one of her episodes with Dr. Dan Katz. Dr. Katz studies airborne pollen - specifically allergenic pollen. If you’ve ever wondered why some pollen causes so much havoc, or if those pollen forecasts you sometimes see on the local weather are accurate, stay tuned to learn more.

Find Allasandra on Instagram and TikTok, and her podcast is on all of the usual podcast services, and the web at The Happy Botanist podcast.
