Abraham Halsey and the New York Lyceum: Uncovering the origins of New York botany
Abraham Halsey and the New York Lyceum: Uncovering the origins of New York botany
Abraham Halsey was a founding member of the New York Lyceum and published the first checklist of New York City lichens in 1823. It was the first work focused on lichens in North America. Halsey's collection, along with the rest of the Lyceum's vast holdings, has been believed destroyed in a tragic 1866 fire that consumed a city block of Manhattan. Join Dr. James Lendemer as we resurrect the legacy of this pioneering naturalist, his rediscovered herbarium and shed light on the little-known origins of New York botany. The talk will highlight the wealth of irreplaceable information in New York State botanical co...

How do species interactions shape the evolution of flowers? A study of California native annual wildflowers in the genus Clarkia. Darwin famously identified that species interactions in a “tangled bank” could influence how species evolve.

Adventures with Arbuscular Mycorrhizal Fungi: Host regulation under combinatorial nutrient stress
Просмотров 2,9 тыс.Год назад
Arbuscular mycorrhiza (AM) are a class of mutualistic, plant root-associated fungi that are believed to have helped make the terrestrialization of modern land plants possible. As an obligate mutualist, AM are dependent on their host plants for carbon in the form of photosynthesis-derived sugars and fatty acids. In return, AM are able provide mineral nutrients, such as phosphorus and nitrogen, t...
Not All Bad: Gyromitrin mycotoxin has a limited distribution in edible false morels (Gyromitra)
Просмотров 804Год назад
False morels (Gyromitra spp.) are iconic fungi primarily for what they are not - morels (Morchella spp.), the highly sought after, wild foraged mushrooms. Every morel hunter is taught to recognize and avoid false morels because they may carry a mycotoxin called gyromitrin (acetaldehyde N-methyl-N-formylhydrazone). While there are only a few deaths associated with gyromitrin in recent times, poi...
The pollen virome of wild plants and its association with floral trait variation and land use
Просмотров 1292 года назад
Pollen is a unique vehicle for viral spread. Pollen-associated viruses hitchhike on or within pollen grains and are transported to other plants by pollinators. They are deposited on flowers and have a direct pathway into the plant and next generation via seeds. To discover the diversity of pollen-associated viruses and identify contributing landscape and floral features, we performed a species-...
The Biology Behind Zombie-Ant Fungi
Просмотров 5972 года назад
The ability to infect insects arose multiple times along the evolution of Fungi. However, none have shown such broad and sophisticated strategies to infect, persist and transmit spores than the so-called “Zombie-Ant Fungi”. These fungi evolved the ability to make their hosts to leave the colony, climb up to a summit position on plant parts and bite onto the substrate. The infected ant remains a...
Cytogeographic, morphological, and genetic variation of the cactus Cylindropuntia leptocaulis
Просмотров 1072 года назад
Polyploidy (i.e., whole genome duplication), hybridization, and reticulate evolution have long been recognized as key mechanisms of speciation in the plant family Cactaceae. Polyploidy can result in reproductive isolation, changes in genetic diversity, breeding system discrepancies and gene regulation effects, which consequently can lead to shifts in morphology, physiology, and ecological bread...

Excellent
Could that bacteria that lives inside the fungi be acting like our mitochondria? Thank you for your brilliant exchange!!!
Excellent presenter and fascinating topic =) Thank you for sharing such high quality content
I just came here to check how many views such a presentation would have. Maybe an easier title would result in more views?
The toxin Gyromitrin, is water soluble, and has a boiling point of 289 °F. The people who survived eating it prepare the false morels in a bath of salt water before frying it in oil or lard at a temp of 350 °F. The salt in the water will leech the toxin Gyromitrin out of the false morel and slightly dehydrate them. Then you can put them in a bath of fresh water with no salt to rehydrate the mushroom tissue. You can also dehydrate them afterwards to draw the remaining toxins out further. But the salt bath seems to be enough for pre-cooking preparation as long as the cooking temperature is above 300 degrees Fahrenheit. At a temperature of 289 °F, the remaining toxin will start to fry out of the mushroom tissue and into the air. Real morels have a small amount of this toxin too and is the reason one should not eat morels raw or one will get diarheah, nausea, and vomiting in about 12 hours. With this information, we suggest one prepare your mushrooms in large batches. Make the water as salty as the sea to leech out the toxins. You can then boil them in fresh water if you want to be extra safe. Although, boiling at boiling point of water at 212 °F isn't sufficient to gas out the toxin. Dehydrating the mushrooms for 3 days may help. But these step after the salt bath do not appear to be necessary for those who consume false morels by traditional methods. After the salt bath, you can drench them in flour and then deep fry them up at a temp of 350 °F.
i got brunnea and one that looks more like the korfii. logan county ohio. also ate the brunnea just some salt water to get rid of any bugs. rinsed. and fried up with eggs veggies and seasonings. did not try eating the korfii looking one since i am unsure on I.D.
Do you have a picture of the brunnea?
@@DallasFeys several pictures. some found in the wild some found in the skillet lol
Well I got good news for you: The gyromitrin-bearing species, G. esculenta group, doesn’t occur in Ohio. G. esculenta group likes cooler climates, either in the mountains or in the far north (like central-northern Michigan, New England, etc.)
I actually started the germination process on 12 Nymphaea Cerulea seeds today
What is with teachers like this that repeat the evolutionary talking point, which has not context to today, as none of us were there and don’t really know if it happened they way they say.
Thank you for the amazing presentation!
The evolution of the species is a sequence, son, parents, grandparents and so on so forth. The sequence logically can not be infinite therefore the debate "creation or evolution" is a false dichotomy. The truth is the universe was created from an eternal entity superior to oneself and it evolves according to the natural laws. An eternal or uncreated entity is not the same as an eternal or infinite sequence of causes and effects. The most important and urgent question is "is atheism a logical fallacy?". Atheism is a logical fallacy that assumes God is the religious idea of the creator of the creation to conclude wrongly no creator exists because a particular idea of God doesn’t exist. God is necessary because logically it is impossible the existence of the creation or finitude without the creator or infinitude. Atheism is the belief immune to arguments that all reality is creation. Creation is what has a beginning of existence. If you understood God is necessary would you live lying deceiving innocent and vulnerable children defending an idea without any arguments? I am not talking about faith, but logic and reason.
First of all, thank you for such an insightful lecture on AMF. I was wondering if you could tell me how the rice plants were inoculated with the AMF? I'd love to know more on how to successfully inoculate trees at a large scale in the wild. Also, still trying to figure out how AM survives/moves to the next tree when a tree dies 😅
Excellent talk. Very helping.
This is fascinating, I’m totally dorking out on this.
Terrific presentation, so cool that someone is working on this stuff!
12 minutes in and still waiting for someone to address the topic. Already there has been misinformation by the guest speaker. Well I'm already this far in I guess I'll keep watching.
we have chapters on all of our videos so you can skip the introductions and go right to the lectures! hopefully you kept watching :)
what misinformation was there in the first 12 minutes?
