I'm a first year PhD student studying for my qualifying exam in a little over a month, this was an amazing review of my Classical Ecology course last semester! Thank you so much!
This randomly showed up in my recommended videos and I'm so grateful! I've missed crash course so much and as a master student in marine ecology I enjoy learning more about the history of my subject
Crash Course: *The Savior of all High School Students*
Indeed
I would not have survived my college world history class and 2 required psychology courses without crash course.
I graduated from high school way back in the pre-9/11 era, but I still watch these vids to help keep myself from getting stupider.
Hey Crash Course! I would just like to state a tiny thing that was wrong. At around 5:30 you said that Teddy Roosevelt created the NPS, but the NPS was created in 1916 and TR was president in 1901-1908, therefore the NPS was created by President Woodrow Wilson, not Teddy. Although he didn't create the NPS, Theodore was a big conservationist creating nearly 5 new National Parks during his presidency. Sorry, the National Park Nerd in me came out and I just wanted to let you guys know!
He did dedicate the first national monument, Devil's Tower... but yes you're right.
Teddy also had part in the start of the United States Forest Service
my boi you are damn right, didnt even pay attention to these
E
The study of the ecosystem and how taking one element out or inserting an invading species changes the entire system. Thanks, Hank
Crash Course Ecology was the first Crash Course series I ever watched. I binged the whole series in one coffee-fueled night. This brings back fond memories :)
What if the Earth were just a big, sophisticated computer, and we were all part of an outrageously complex program designed to calculate the Ultimate Question of Life, the Universe, and Everything!?! 😉
(Sorry, just felt compelled to bring-up _Hitchhiker's_ for a second.)
I don't take bio anymore but I still enjoy watching these
Hello dad
yeah same here :)
Go home Dad, you're drunk.
This has been my favorite series yet
Even though I don't study Ecology, I study English. I know I'm going to love this series
Considering you study English, that was not a very well formed sentence.
@@chloebutler8438 Amm that was informal writing. And I don't have to please you. That was me commenting on my favorite TH-camrs' channel
Communities all the way down.
This is my Biology's Class topic😎💓
yes thank you for the ecology representation, i feel like people treat us like we are a joke : (
Thanks for great course! You not only show the history of science but also tell how our world changes with effort of different people. It is inspiring!
I make my own dinosaur documentaries. They sort of deal with ecosystems but they also connect with the Jurassic park story.
Ecology is a great subject to take in school! 🔥🔥🔥🔥🔥🔥🔥🔥🔥
CC Systems Theory (and why it matters).
i want a humboldt-episode! please please!
How dare you speak about the origins of ecology without mentioning Alexander von Humboldt! He inspired both Darwin and Haeckel greatly :(
Yes thank you!! I was just about to post that! It's a pity his name is largely forgotten these days even when he influenced so many others back in his day
yeeees, humboldt! he was amazing!
Right!! So disappointed to see he hasn't been mentioned once in this entire series!! :(
Good stuff, I feel proud to know that I study in the school Odum founded.
This explains so much about how the offices of the different research groups are located vis a vis each other at my uni
seeing this title and wanting to beco,e am ecologist when i "grow up" is really exciting
Amazing summary of the history of ecology! As an ecology phd, I learned a lot!
Really helped with my school work. "Hank the best"
I love learning about science it makes me feel better when I learn more about Charles Darwin :)
Hello Crash Course, I have a question: Will this History of Science include Social Sciences or only Hard Sciences?
Impressive and digestive way of Presentation. Fan of this Channel. Trying to reach the level soon.
You quoted haeckel without ever talking about Alexander Von Humbold, the scientist that Haeckel was referring to when he created the term and also the scientist that inspired Darwin to go on his world adventure...
Disappointed at how USA-centric all your examples are, e.g. national parks, but as an Aussie studying a Masters of Ecology, this was a great episode.
Excelente question! !why don't we have more pics about esrth from space!!!!????
It's a small detail but I'd argue that the field of ecology started earlier than the Cold War with the rise of rangeland management in the western states and territories after the tragedy of the commons lead to the Taylor Grazing Act in 1932. Before then we had the likes of Aldo Leopold (shout out to mah boy) and Gifford Pinchot investigating and observing how anthropogentic use influenced the ecology of an area. The Taylor Grazing Act created a field of employment where there were people specifically dedicated to balancing use and function on a landscape, really kick starting the field of ecology in my opinion. This did expand during the cold war era, however, when the Multiple Use Act was passed in 1960, the Rangeland Improvement Act, and the creation of NEPA.
Awesome episode! I've chimed in a few times to critique or comment or nit pick, but I have nothing really but praise for this episode. It's a good overview.
Looks like there's going to be another one. Hoping to see some mention of the idea of a food web (or the introduction of tropic models as a term), which this episode danced around but didn't quite have time for. It's a little on the philosophy side, but a mention on the limitations and drawbacks of conservation ecology and some of the new alternative ideas would be cool. And, of course, because I'm formally trained in this subject and heavily biased, a discussion on the difference between the cyclical nature of natural systems as opposed to the linear operations of human systems and the inevitable conflict between these two would knock my socks off.
I know it's already made, though, and I'm sure it's going to be good even if it doesn't say exactly what I might have.
Another master piece. I'm glad to learn.
BIOGEOCHEM IS MY FOCUS!
Hank you should visit Grigore Antipas muzeum ^^
Thanks for the history course of ecology. A good summary.
Progress is impossible without change, and those who cannot change their minds cannot change anything.
They can change other people's minds.
People who change their minds a lot tend not to accomplish much, either.
Well done, CrashCourse.
Amazing video. Thanks for upload these contents, following you guys!
Not only did Odum teach at UGA, he founded the Odum School of Ecology to make ecology an independent form of study!!! Source: I got my degree there :)
Yall need to get a sturdy desk.
4:12 I see what you did there with the just a theory.
No mention of Charles Elton?
Nice work
Great episode!
Go Dawgs!!!
The noosphere idea was founded by Pierre de teilhard chardin. Him and his buddy henri burgsen
That idea is interesting
Very interesting!
Hi, I would be so happy if you could tell me which program do you use for creating your videos animations, I think they are amazing. Could you do that?
Thanks, I think that what you do is amazing.
Time for ecology 😍😎
Google Murray Bookchin
Great video, Keep up the good work Crash Course :)
Oh
IT IS ECOLOGY DAY, MY DUDES
ecology is fascinating!
I'm sure Heckel (or Hekel) was more than a hype-man.
So.... will we get a history of Paleontology? Since we skipped it as an episode here, how about an entire series... Crash Course Paleontology!
What happened to crash courses intro?
Earth System Science: is this science that could answer the question "how does the earth uphold its life sustaining mechanisms?"
Historical ecology encompasses all of the data, techniques, and perspectives from paleoecology; land-use history from archival and documentary research; and long-term ecological research and monitoring extended over decades. Multiple, comparative histories from many locations can help evaluate both cultural and natural causes of variability and characterize the overall dynamic properties of ecosystems (Swetnam et al. 1999).
In fact, twentieth-century trends suggest that disregarding history can be perilous. Examples include the emergence of increasingly severe wildfire activity in the western United States and the role of extreme drought in triggering forest dieback and accelerated soil erosion in the American Southwest.
Human-generated changes must be constrained because nature has functional, historical, and evolutionary limits. Nature has a range of ways to be, but there is a limit to those ways, and, therefore, human changes must be within those limits. (Christensen et al. 1996)
A primary objective of historical ecology is to help define the various limits, the natural range of variability for ecological systems (Swetnam et al. 1999). In this way, applying historical knowledge guides and constrains resource management actions to sustainably mesh with those limits.
Environmental history research concentrates on the patterns and causes of ecological changes in the landscapes of these southwestern mountain ranges. It includes extensive work on historic, ground-based photographs for this area, with relocation and retaking of photographs that were taken as long ago as 1880 by the Bureau of Biological Survey, U.S. Geological Survey, USDA Forest Service, early archaeologists, and others.
These episode gives e brief information of ecology. How the nonliving and living things is related to each other. It also shows that in every actions of the living things have effects in the nonliving things. For me this episode is telling us that the knowledge we have about the ecology is must be applied to save our ecosystem.
Ecology is all about study of environment. It became a discipline while science continue studying life and the non-living things that affect life like water and soil. Vernadsky pioneered ways to analyse nature historically. One was the geochemistry, or using the methods of chemistry to understand minerals, another was biogeochemistry which analyses living and non-living processes. The3 scientist use experiments to generate mathematic models tracing the flow of energy from non-living source into primary producers, primary consumers, meat eaters and eaters of dead things. However, our environment is very important because it will contribute in the field of science like the living and non-living things.
Ecology is the study of the interactions of living organisms with their environment. Ecologists study within several biological levels of organization, which include organism, population, community, and ecosystem. I find this very essential to study since it seeks to explain the life process where in it is fact that we're included to it since I believe that everything is interconnected. What we do will be the product of what is happening right now.
Ecology by definition states that it involve studying the life and the nonliving things that affect life like soil and water. Answering why is it significant to us? Because it helps us understand how the world works. It provides useful evidence on the interdependence between people and the natural world, as well as the consequences of human activity on the environment.
Here are some of the questions answered by British Ecological Society:
Can we conserve a habitat and its biodiversity?
Yes. Ecology provides the essential basis for nature conservation. Maintaining a mosaic of habitats ensures the survival of a rich variety of species.
Can we predict the ecological effects of pollution and climate change?
Governments and citizens around the world are increasingly aware of the consequences of atmospheric pollution and climate change. In large-scale experiments, plants and animals are exposed to carefully controlled atmospheres and different ecological conditions. Scientists use this information to understand how they respond to pollution levels, and make predictions about future climate change.
Can we fish the ocean without depleting its riches?
It is possible, but does depend on where we are in the world. In the Antarctic, the marine ecosystem is currently managed as a whole under an international agreement to conserve living resources.
How does forest destruction affect bird populations?
About one third of forest bird species cannot live in small remnants of forests. The smaller birds such as the forest robin will use patches as small as 10 ha and the largest species, such as the brown-cheeked hornbill, need patches bigger than 10 square km.
Should mangroves be protected?
Mangroves play a number of ecological roles from fixing sediments to acting as nursery site for young fish. Mangrove forests are also a source of food, medicine and firewood for local populations.
Ecology time? I thought it was pizza time
CC Clemens?
Correction: soil is living.
Go check out Peter Joseph.
Someone (even a non CCer) should do CC Bernatsky or something.
cough cough Vernatsky, of course I know that cough cough (I totally did not).
Just discovered you today; it's very interesting courses, thank you! But, can you talk normally with slower pace and less monotonous? I find that with your speaking style so much information just easily slipping away.. thank you..
🤣
Chaos theory?
No Alexander von Humboldt? Tisk tisk
But wait, you didn't mention my favorite scientist! I'm so mad I will reply to all comments and tell them that Tesla is better than any scientist from this video.
Wassup
Great Episode. Are you going to do Social Engineering?
Sounds like someone applied the power of distribution and transformation on the planet? ??
I'm here for a quiz. :3
This would’ve been really helpful like...last week....
Who knows noosphere from STALKER game
"memento mori"
Here before 500 views?
idk, making sicc memes is pretty important
You look tired Hank. Are you okay?
I made a song about the history of science as it pertains to ecology!@
Don’t forget the Paris Climate Agreement! Oh wait..
😥
Im early, I wish I could think of a good science joke.
Wellcom to my channal for seance
If you want your dream job, get your degree in ecology!
Great channel 👍655👍👍👍👍👍
Eighteenth!
Stop making that noise whenever the graphics change; it's annoying and very distracting, especialy when it happens several times in a row. 😒
Shouldn't meteorology be part of ecology?
The climate is of a essential importance in ecology, but it's another thing. Ecology has its focus on how >living< things interact with each other and the enviroment.
I guess you could say these scientists were a bunch of...Eco Geeks.
1th
wow
Prvi
First
Most boring ep!
