Variegation among leaves is a fascinating phenomenon. Though plant breeders have accentuated this trait in a variety of cultivated plants, variegation does occur naturally as well. Its function isn't well understood for most species either. Such is the case for two species of wild ginger in the genu…
Islands are hotbeds for unique biodiversity. Strange and unique island plants form the foundation of strange and unique ecosystems. Sadly, the human hand has not been kind to Earth's island ecosystems, especially in recent times. The introduction of invasive species like rats, cats, and goats have b…
The Adirondack Mountains are home to a remarkable diversity of plant species. Situated in northern New York, these mountains are harsh enough that they foster a thriving alpine community. Despite their ability to handle some of the worst weather conditions, alpine plants can be quite sensitive to hu…
While there have been some recent set-backs within science and climate research and disturbing news about NOAA, there is also continuing efforts on responding to climate change. During my travels to Mozambique and Ghana, I could sense a real appreciation for knowledge, and an eagerness to learn how …
Invasive species reduce native biodiversity and hinder an ecosystem's ability to support life, including our own. Managing invasive species can be very challenging, but that doesn't intimidate people like Dr. Mike Schuster. Learn how he and his colleagues are using the ecological principal of biotic…
Grasslands and fire are essentially inseparable. For the most part, grassland can't exist without periodic burns. But, are the beneficial effects of fire the same for all plants? How do the effects of fire change across scales? These are the kinds of questions Dr. Jared Beck and his colleagues are t…
Plants cannot run away from the herbivores that eat them, therefore plants have evolved numerous strategies to defend themselves from being consumed. Plant defenses are as varied as the plant kingdom and the ways in which they operate will blow your mind. We are joined by Dr. Rupesh Kariyat who stud…
Coral reefs are powerful, resilient ecosystems supporting 25% of all marine list and over a billion people globally. But these ecosystems are fragile and pollution is one of the most immediate threats they face. While climate change grabs headlines (and is still very important), local pollution is d…

Domestication is a spectrum, especially for botanical crops. Regardless of where a plant is on that spectrum, it nevertheless has a wild origin. Understanding those origins can not only help us understand the plants better, but also our history as a species as well as open the door to future possibi…

Sedges are a complex group of plants in the family Cyperaceae. Within this family lies the genus Carex, which boasts ~2000 species found in all kinds of habitats. From specialists to generalists, there seems to be no lifestyle the sedges have not experimented with. But how did all this sedge diversi…
Last week, Amazon Conservation Co-Founder Dr. Adrian Forsyth joined our Peruvian sister organization, Conservación Amazónica-ACCA, for a special event to celebrate the launch of the Spanish edition of his book, Tropical Nature (Naturaleza Tropical), which transforms the ecological complexity of trop…
Scientists from Scripps Institution of Oceanography at the University of California San Diego were able to ‘hear’ the impacts of a marine heatwave and even economic slowdowns by analyzing 15 years of ocean sounds recorded off the coast of Southern California. The recordings, collected between 2008 a…
Fish make hanging motionless in the water column look effortless, and scientists had long assumed hovering was a type of rest. Now, a new study reveals that fish use nearly twice as much energy when hovering in place compared to resting. The study, led by scientists at the University of California S…
What do witch hazel seeds and a speeding bullet have in common? Acceleration! Join me and Justin Jorge as we explore the ecomechanics of seed dispersal in Loropetalum chinense, Hamamelis virginiana and Fortunearia sinensis. This episode was produced in part by Heidi, Kristin, Luke, Sea, Shannon, Tho…

Over multiple generations of CMIP models Arctic sea ice trend predictions have gone from much too stable to about right. Why? The diagnostics highlighted in our model-observations comparison page are currently all temperature based, and show overall that climate models have being doing well on these…
Say "old growth" and we all too often picture ancient forests with large, gnarly trees. However, forests aren't the only habitat types that can reach old growth status. Prairies, savannas, and woodlands can be old growth too and it is vital that we both protect and learn from them as they are one of…
Any organism that ephemeral gravel puddles home must be ready to deal with extremes. That is what makes snorkelwort (Gratiola amphiantha) and its aquatic neighbors so darn cool. It's what also makes it so very rare. Join me and Anna Wyngaarden as we take a deep dive into how she is trying to solve s…
The world of aquatic plants is incredibly diverse, yet our ties to land make it difficult to fully appreciate these organisms. Their glory and splendor is best observed in their underwater realm. This is why aquascaping is such an incredible hobby. Planted aquariums provide you with a unique view of…
Pinesap (Monotropa hypopitys) produces no leaves nor any chlorophyl. It “eats” fungi and can be found growing in many areas around the globe. It flowers in spring, fall, and summer and noby really knows if it is a single species or many. Despite its uniqueness, relatively little scientific attention…
This episode celebrates moths as pollinators. We ignore or even malign moths at our own peril. Dr. Stephen Robertson joins us to talk about how even crop pests can act as important pollinators. From their bewildering numbers to the ways they interact with daytime pollinators, Dr. Robertson will open…
The High Arctic is not a place you go looking for forests today. It is extremely harsh, cold, and nearly void of most forms of plant life. However, that has not always been the case. The Eocene Epoch was a period where Earth was much hotter than it is today and forests flourished at the poles. This …
Oceana’s Dr. Kimberly Warner explains what you need to know about the tiny plastic particles. When we think about plastic pollution in the ocean, we might picture plastic bottles and bags strewn across beaches, floating atop waves, or endangering marine wildlife. But there is also a more insidious s…
Imagine diving into clear blue water. Schools of fish dart past. Coral fans sway gently with the current. And then you see it—a net, tattered and tangled, drifting like a shadow. Silent. Suspended. Deadly. This is ghost gear. And it’s one of the most lethal forms of plastic pollution in the ocean. …

Knowing what we don't know can be as important as knowing what we do. Even highly charismatic plants like orchids harbor many mysteries in need of investigation. Join me and Dr. Adam Karrenmans as we discuss his new book "Demystifying Orchid Pollination" and learn why paying attention to nature at a…
If a volcano erupts underwater and no one is around to see it, does it actually happen? Turns out, 80% of volcanic activity occurs in the sea, but it often receives less attention than its aboveground counterparts. Fortunately, one underwater volcano is bringing the discussion to light. Hundreds o…
Preparing for a second Trump administration in the United States, Oceana’s Beth Lowell reflects on past lessons and future plans. In polarized times, how do you bring people together to protect and restore the oceans? BL: Thankfully, protecting the oceans isn’t a divisive issue. In every public …
Sometimes the differences between species are vast (e.g., a maple and an oak) but other times they are subtle to the point of requiring a trained eye and essentially learning a new language. So-called cryptic species are extremely challenging to understand, but that is why spending time in the field…
Restoring healthy wetlands isn't an easy task. Often times, altered hydrologic cycles means wetlands no long act like they once did. Nevertheless, the many ecological and cultural benefits of functioning wetlands means that wetland restoration is certainly worth the time, money, and effort. Join me …
Plants ARE habitat and that doesn't stop when they die. Countless species of microbes, fungi, arthropods, and more not only take up residence in dead plant material but also require it to complete their lifecycle. My guest today is Dr. Amy Zanne and she spends a lot of time thinking about the things…
What wetland scene would be complete without a few cattails? The genus Typha is synonymous with wetlands yet as you will hear in this episode, we know so little about them. Joining us is Dr. Pam Geddes from Northeastern Illinois University to talk to us about her work on cattail invasion ecology. Wh…
