In this episode of The Southern Naturalist, Dr. Bob and Dr. Aimée Thomas explore the slimy, strange, and surprisingly intelligent world of slime molds — with a special focus on the infamous Fuligo septica, also known as dog vomit slime mold. Despite its less-than-appealing nickname, this bright yellow protist is a marvel of biology.

Slime molds are cosmopolitan species, meaning they can be found all over the world — from your backyard mulch pile to deep forest floors. While F. septica takes center stage, we also explore a range of other slime mold species and what they reveal about the natural world.

These unique organisms have long defied easy classification. Though they’re often mistaken for fungi, slime molds are actually protists — a fascinating group of life forms that blur the lines between what we think we know about cells, movement, and even behavior.

We discuss how scientists use slime molds to study things like traffic flow and network optimization, how some slime molds can “solve” mazes, and how their behavior continues to baffle researchers. You'll also hear about the strange folklore that surrounds slime molds across cultures and why these humble blobs have captured the human imagination for centuries.

Whether you're a slime mold skeptic or a full-blown myxomycophile, this episode is a deep dive into the gooey, brainy, and totally bizarre world of some of nature’s most overlooked organisms.

In this episode of The Southern Naturalist, Dr. Bob and Dr. Aimée Thomas explore the fascinating science behind why some trees, like the Japanese magnolia, burst into bloom before their leaves emerge. Why do these early bloomers put on their floral show in the chill of February? How does this strategy benefit them in the grand cycle of nature? Join us as we dive into the evolutionary and ecological reasons behind this stunning phenomenon, with a special focus on the southern landscapes where these trees thrive.

Dr. Bob and Dr. Aimee Thomas dive into the prehistoric world of the alligator gar, a true living fossil that has roamed North America's waters for over 100 million years. With its armor-like ganoid scales, air-breathing swim bladder, and ambush predator instincts, this ancient giant has remained virtually unchanged since the age of the dinosaurs. But despite its primeval legacy, the alligator gar is often misunderstood and even maligned. Join us as we uncover the fascinating evolution, ecological role, and conservation challenges of this Jurassic-era relic.

Did you know that bull sharks have been found in rivers 1,800 miles away from the ocean?

In this episode we are joined by Dr. Martin O'Connell, a scientist who has extensively researched sharks and other marine species. We dive into the history of bull shark encounters in Lake Pontchartrain and other estuarine areas. We also explore WHY these sharks come into the lake, their role as an apex predator, and our own feelings about swimming in the same bodies of water with these fascinating creatures.

In this episode we dive into the natural history of Cuban treefrogs (Osteopilus septentrionalis), how they compare to our native green treefrog (Hyla cinerea) and how they recently became established in Louisiana. Dr. Bob has been on the pulse of this frog invasion and identified some of the first visitors to Louisiana in the 1980s! Naturally, we compare the cuban treefrog to other invasive species in the area, such as the brown anole (Anolis sagrei), the greenhouse frog (Eleutherodactylus planirostris) and nutria rat (Myocastor coypus). We get into the condumrum of invasive species… how do we deal with them?
