Geeks lecture better than the professionals🤔

Really great paleobotany presentation. Also, I had not heard of the fungal infestation defence of warm blooded animals before.

👍⭐⭐⭐⭐⭐

Didn't even talk about the plants of the ediacarin period

Fantastic information thank you

Great lecture! Thx

The grove of jewel weed has been mowed down by the city along with other Lake Atalanta wildflower "gardens". 😪

Hello i have an urgent question: When the plant life exploded in the carbonferous and the CO2 was reduced drasticly from the atmosphere, why did the temperatures not change? Only untill ~50 millions later with the Karoo ice age? At 18:40 it is said that the CO2 reduction is caused by the few cambrian plants and this lead to the Andean-Saharan glaciation. That is not only uncertain but unlikely in it's drastic effect and not in line with the jurassic CO2 decline with temperature rise for example. The cold itself is the major reductor of CO2 due to the absorbing oceans. The real reason for these drsatic temperature changes is the continetal distribution. When Antarctica left the south pole in the permian, the hot mesozoic began and when Antarctica turned back to the pole, our ice age began. Snow can not accumulate to large ice shields on the open seas.

When will the inventory be published?

So interesting ! Thank you.

What a wonderful addition to the Awards program. And how wonderful it has been to have known Eric and Milane throughout the years. Thank you for recognizing those who have brought so much knowledge and warmth to ANPS. The idea of honoring a partnership is just especially appropriate.

The universe seems to have provided everything needed for the development of life on all levels.

Great presentaion! I will habe to watch again!

Well done, interesting. Thank you, I will save it for reference.

Great presentation! The pictures were very detailed and the inclusion of lots of background color made them very nice to look at. Thank you for the information on historical resources and for your contribution to keeping native plants in the public consciousness.

If human disturbance and invasive species are always hand in hand. Which, I think we can agree that they are. And humans, along with invasive species, are dcreasing the availible land for native plants. Then what role do you see humans playing in conservation if 'invasive' and 'weed' descriptors are, in your words, "mental constucts"? Are you suggesting that there is less existential threat to native species than previously thought? Or that invasives can be equally beneficial to our ecosystems and nonhuman individuals?

Excited to see this.

Another fantastic overview of basic botanical terms that can be taken into the field and actually used! Thanks so much.

excellent, I taught myself mushrooms (the poisonous ones first) over 50 years ago, but this was mostly new and more interesting information to me, I am gonna go look and see if I can find if Jay Justice has anything else up online.

Lecture catering to my current interest. I was specially interested of Devonian plants. Carboniferous had also fascinating shapes.

By far the most useful, concise and practical introduction to plant ID I've come across on the web. Thanks so much!

I don't hold with your statement that cold bloodedness killed off the "reptiles" at the Cretaceous-Paleogene extinction and allowed the warm blooded mammals to rise. Dinosaurs were not reptiles for one thing. There is a difference between a reptile and a dinosaur. Furthermore, there is strong evidence that dinosaurs were warm blooded. The atmosphere and the nuclear winter-like conditions after the impact killed off most things and it was the fact that mammals were burrowers that allowed their continued existence not their warm bloodedness.

Thank you sir.For this informative video..Respect from Bangladesh...❤

I just love listening to these kinds of videos

The picture in 16.30 from early Devonian, painted by Z.Burian, was the first picture about paleozoic plants I have ever seen. It was in an old paleo book from the 1950s wich belonged my grandpa, but I loved it! Of course there were a lot of wrong things in this book, so all the Silurian and early Devonian plants were called by the same name "psilophytales". But there were many beautiful pictures from the Devonian and Carboniferous in this old book, and they made me getting interested in paleontology and paleobotanic. And the Carboniferous is still one of my most favourite periods in earth history, I would love to have some of the trees like sigillaria or lepidodendron in my garden. And also some Devonian plants, like Asteroxylon or archeosigillaria....😊 I would also like to know more about the Evolution of the angiosperms in the mesozoic, but there are still a lot of unclear things I guess... Best wishes to you all from Germany, and I hope to see more of your videos!

Imagine rummaging through boxes and boxes of plant fossils, and helping yourself to whichever one you fancy.

Benton and Washington counties? That's not northwest Arkansas

Great information!

"promosm"

That was fascinating! Just one point of critique; To have the Eric Fusilier visible in a box at the margin of the slides would make it easier to follow the presentation. As I am a typical member of the ape family, eye contact helps me to focus my concentration. Anyway, thanks and greetings from Munich, Germany.

Who in the world would have thought that In the Archean Eon stromatolites had to pay for oxygen! Wonder what currency they used?

Thank you so much, Eric et al. I learned a lot. 🙏

So helpful!

Doc….you totally remind me of Rick from Rick & Morty…voice act bro.

Very informative and beautifully presented. The content is well organized and the way Doc build up momentum the things start percolating deep into the mind. If possible, share the pdf of this presentation. Best wishes

Very thought provoking presentation. Well worth my time. Thank you, ANPS!

Sir, you are long-winded. you need to stop this babbling and get to the jist of things

Very cool pic of the LiDAR view of the waterway change😎

Nice job, Caity. I appreciate your hard work and dedication to conduct and complete your research. Pictures and video added a nice touch to help us really identify with the island. And for the referral to Quapaw Canoes! Sounds like a nice outing to plan.

Every time I listen to a presentation by Dr. Abbott I learn more than the time before. At first, it seems overwhelming, but the underlying concepts eventually make a lot of sense. My favorite parts of this particular presentation are his self-effacing sense of humor when he shares his own struggles with pronunciation of tongue twisting words and his willingness to admit he, too, is still learning all the time. He remains an inspiration to me and I am so grateful for his willingness to share his expertise with laymen like myself.

Great information but I fear it would take me years of study to master this. My Latin background helps but only slightly.

LOVE THIS! thanks for part 1 recording! I’ll be on the live part 2! :)

Thank you so much for uploading these videos. It's a great way to open up the community to citizens and involve everyone interested in the nature around them

Cherrie-Lee Phillip Cherrie-Lee Ph This was my introduction to plant taxonomy and I totally loved it! Thank you.
