Good job, Amanda. It's always good to refresh the basics.

WOW! I graduated in Biology in 2001. I recall how it was difficult to get any information without resourcing to our library. and teachers showing off their cell phones, because they were the first to buy some. It was literally the Stone Age. Thanks for the video.

Getting u well

Thanq so many ch mam .superb explanation

Nice 👍 please explain in gujarati

I support and respect your courage . The contribution you are making through these videos are extremely helpful. Thank you and I wish you will continue the tradition for the welfare of future biologists. Even though there are not many views in your videos but remember the fact that the process of creating a history begins from the cave only where u are alone .😊 Thanks you 🙏

.no homospory or heterospory 😮

❤❤❤❤❤

You should make shorts on bio /zoology. So you get more audience

Plz more videos on zoology. ♥️ from india

Soo nice explanation dear 💕💕💕💕💕

Very helpful!

Wow 😮😮🎉❤❤ I love it 💕

I love this video - ferns are my favorite plants and this is such a well made, professional overview , very good job. I do have one thing to say about lycophytes though - just because I also love paleontology - for sure, modern lycophytes are all small, but during the paleozoic there was the order lepidodendrales (which i think are probably most closely related to spikemosses?), which could get enormous, i think some specimens are estimated at like 130 ft tall. I don’t think they had true wood though, more of a stiff stem like structure. It’s not necessarily a criticism that you didn’t include them in the video, I just think that they’re cool.

Superb

Most useful video

Louder n clear

i dont understand the problem or the science behind it or know how much sense proposed solutions make. im sure there are situations where it doesnt matter if invasive species are grown, like in a pot on your property where it will never spread anywhere

Great detailed video Very informative Very professional Thank you

Great video!

First of all thank you for all the videos you publish. I do field recording so this one is good to have an overall overview of biophony. Nowadays we could add a parameter which is the presence of human disturbance. How are biophony and antropophony related, how do animals respond to the loudness of traffic for example, how can whales and others keep their communication with that much of sound pollution coming from boats as sound travels more freely in water. And there is the part of sound that we humans simply do not hear: ultrasound. I have many ultrasound activity in some recordings that are not in the human hearing range. This can be pitched down but I like to keep it the way it is and accept the flaw in our hearing capacities. Again keep up the work you do. I came here for the ferns and now I have been looking at several videos!

Can you upload more videos of botany for example - related to Anatomy, Morphology, plant physiology. Thnks for this video, excellent work. Regards - Rajesh ( from India🇮🇳)

the first one on comment,it is very teaching i appreciate you with subscribing!!!!

Awesome, thank you so much

Im a gymnosperm ally!

All night long she was a young gametophyte.

I like moss.

Well explained ❤

Now I understand the plant world so much better.

These Beck Bio videos are terrific: concisely informative, visually rich, and entertaining. Please continue making them.

I thought ferns were polypodiophyta so I looked it up and it's saying pteridophytes includes polypodiophyta, as well as lycopodiophyta, and equisetophyta. I've never heard the term "pteridophyte" before. Thank you for sharing. They didn't say anything about psilotophyta. Would that be included in pteridophytes?

thanks for a nice explanation!

Finally the algorithm serves me up something decent

Thanks 👍🏻
