    Codi Lazar is a Professory of Geology at California State University San Bernardino and a passionate and utterly hilarious geologist. In this episode, we get into the weeds talking about a wide variety of topics such as how limestone forms, why some plants might be restricted to it, what "serpentinite" is, what's in story for the state of Nevada in the next few dozen million years, how related the granite that's beneath Joshua Tree National Park might be to the granite in the Sierra Nevadas (very), the former love affair between the African continent, Scottland, Newfoundland and Appalachia, and much more.

    The genus Baccharis is one of the largest and most diverse in the Composite Family, Asteraceae. It originated in South America a few dozen million years ago and has diversified and spread throughout South and North America and adapted to a variety of different habitats due to a number of key innovations such as tufted trichomes that secrete sticky wax, the abundant production of wind-dispersed seeds, and rapid growth, among other traits. When I was working for the railroad and frequently visiting abandoned industrial corridors in California, the genus Baccharis was one of the only native plants that was able to hold its own amidst the concrete, pollution and toxic soil of former industrial sites.

    Today we talk with Baccharis researcher Gustavo Heiden from Southern Brazil about his research and study of this tough and remarkable genus, where it originated and what makes it so successful.

    Plant Anatomy, Again with Dr. Jim Mauseth

    Did you know that the distal ends and tips of roots are the only parts doing any absorption? What the hell are cortical bundles and why did cacti evolve them? How can cactus roots grow so quickly after a rain and what do we mean by "root spurs"? How does the South American parasitic plant Tristerix aphylla behave like a fungus when it grows inside its host plant? And if you still don't understand what the hell Parenchyma is, here's your chance for a refresher.

    Dr. Jim Mauseth taught plant anatomy and botany for 30 years at UT Austin and literally wrote a textbook on the subject. He's also written a few other books and over a hundred research papers studying the anatomy of plants with an emphasis on cacti, and has traveled to South America and Mexico studying the family on numerous occasions. In this episode we go deep on plant tissues, plant cells, cellular components, plasmodesmata, cell membranes and how the a plant is technically only one single cell when you really get down to it...

    A reminder that the previous podcast episode on plant tissues covers some of the terminology in this episode, such as the 3 main tissue types : epidermal tissues, ground tissues (parenchyma, collenchyma, sclerenchyma) and vascular tissue (xylem and phloem). I highly suggest listening to that episode first or at least pausing the podcast if you're unclear about some of the terminology. Remember that tracheids and vessel elements apply only to xylem (which only moves water) and "sieve tubes", "companion cells" and "sieve plates" apply only to phloem (which only moves sugars and photosynthates).

    The 3 ground tissues are : parenchyma (primary walls only, large intercellular spaces, alive at maturity), collenchyma (only produces primary cell walls with thickened and re-inforced corners, alive at maturity), sclerenchyma (primary and secondary cell walls, dead at maturity).

    A reminder: the ads on this podcast (as well as most podcasts) are terrible. You can get AD-FREE versions of this podcast episode on the crime pays patreon (https://www.patreon.com/CrimePaysButBotanyDoesnt)

    In this episode:
    We talk about the three main types of tissue systems in plants :

    Dermal (trichomes, guard cells)
    Ground (Parenchyma, Collenchyma, Sclerenchyma) &
    Vascular (xylem and phloem)

    What the hell are these tissues? Whatta they mean? Whatta they do?

    Christ Best is the State Botanist with US Fish and Wildlife Service for the state of Texas, a position he has held for 30 years. He has extensive knowledge of plants in the Rio Grande Valley of South Texas, specifically. He has worked with numerous rare and endangered plant species including Physaria thamnophila, Asclpeias prostrata, Thymophylla tephroleuca and many more. He has also worked with mycorrhizae on cactus roots, propagating rare and endangered species, and navigating the sometimes tenuous relationship with private landowners in the state. In this episode we talk about propagating rare plants, fostering symbiotic relationhips between roots and beneficial fungi and bacteria in the soil microbiome by intentionally innoculating plants in propagation, endangered plants, peyote conservation (or lack there of), how geology can affect the plant species that occur in an area, and what random but interested people can do for plant conservation.
