Community Ecology and Landscape Ecology

With a better understanding of population ecology, we are ready to zoom out and look at community ecology, which involves interactions between species, as well as landscape ecology, which will broaden our understanding of ecosystems. How are communities structured? What are ecological webs? What is resource partitioning? Or succession? What about the urban-rural gradient? So much to talk about!

I learn more about science in a day by watching Dave's videos than I do in a whole week at high school. Thank you so much for being born Dave. People like you are a symbol of hope and a great inspiration for young people who want to get into science. You deserve to be the next Carl Sagan or the next Bill Nye and you deserve to have as many subscribers as Mr. Beast. Keep making the world smarter, and never stop fighting flat earthers and young earth creationists.😊

Education must be bad in the usa. This is part of the biology lessons in the Netherlands. We have a different school system. But this is teached in the higher levels of education in the schools after primary school.

@@palantir135Education isn’t great here, and it’s worse in poorer communities. Additionally, ‘homeschooling’ curriculum is problematic. Especially those with religious or conspiracy theorist parents who are science deniers- their children are taught to scientists are liars. Young earth, flat earth, secret alien overlords and so on- those children can’t be exposed to the real sciences or they won’t follow their parents belief systems. These videos are also good for people as refreshers, and they are laid out simply enough to understand, no matter the level of education…or prior indoctrination.

Professor dave is perfect for students who already have an idea of the topics, it really helps to solidy knowledge. But to learn anew a real class is always better

Thank you Dave! I love your videos. Informational videos are the best, they really deserve more views. It's sad to see so little interest

I’m starting to learn sciences outside of psychology to gain a better understanding of this world. Dave makes things digestible and not formidable like the environment in a classroom. Maybe I’m not bad at biology and teachers are bad at teaching! Thanks, Dave!

The funniest enviromental change I ever heard of. was when they whent out to check for the enviromental damage a Armoured regiment had. they found a rare herb that only grows where the ground have been torn up. so it grow their because of the regiment.

Somehow, I doubt this, but if you have a reference or link to such a plant, I'd love to read about it.

@@glennpearson9348 It's fairly common in Germany. There are a lot of former training grounds for combined arms exercises that stopped being used decades ago. The effects of tanks plowing through the area have created very special conditions that allow certain species of lizards, frogs, insects and so on to thrive. Once the tanks stopped rocking through the plains, those species had it much tougher or their niche stopped existing altogether. I shit you not, there's nature preserves in Germany where some dude gets paid to drive around in a demilitarized tank every couple of weeks, to maintain those niches. You can actually pay money to ride the tank, I did that with a few friends a couple years ago.

@@h.a.9880 Yep, I've done that too back when I lived in (West) Germany (1981 - 1985). However, there's a difference between creating a habitat that makes it easier for indigenous species to proliferate (e.g., insects that are already there, but do better when the ground is torn up), and creating a habitat that allows an invasive species to proliferate (e.g., a rare herb that "only grows when the ground has been torn up"). Like I said, a reference would be helpful. I'd really like to read more about it.

Hi, Dave. Could you look at _Unzicker's Real Physics?_ He's friends with Sky Scholar, whom you debunked years ago. Remember when Sky Scholar said that the Sun is liquid metallic hydrogen? Unzicker gives a justification for that. Unzicker also thinks the universe isn't expanding. It would be interesting to look at him.

Hey professor dave, I’ve got a question. I came across a flat earth video, and they were claiming the tilt of the earth contradicts the fact that the equator should be the hottest place on earth, thus the earth is flat. Now obviously this is bullcrap, and there is a logical explanation on it, but I can’t find a super clear one. Can you help me out on this one please? Thank you. Edit: fixed spelling error

@themasterone16 6 ай бұрын

I think they are looking at the average annualvtemperature of the equator. However, if you take a look at the average winter or summer temperature of the earth, you'll see it's shifted. Correct me if I'm wrong.

Ah, yes. The glories of urban sprawl. Professor Dave, maybe you'll eventually do a series on how local government works, including a spotlight on planning and zoning commissions. If you want to get to the bottom of urban sprawl, start there. Thanks for the latest ecology installment!

Hello Professor Dave, I was wondering if you could recommend a very comprehensive organic chemistry textbook for me because I would love to have a reference to get back to every once in a while?
