Is there a good way to actually find the parameters alpha, Beta, etc… online for a pair of predator and prey? I’ve tried searching for over an hour and couldn’t find anything that’s just a table of values more or less. Every video and article just brings up this equation but not the method to actually obtaining the parameters and how to model it
Dear professor you explained it well but I got a point why you put positive sign in the predator eqquation if there is no prey so i think the growth rate will go decline I mean negative sign there should be instead of positve sign
The predator population will grow in size by feeding on the prey, the positive sign indicates that the more the predator interacts with the prey population they feed and grow in size
@@EndlessEngineering Yes, but more eating means less prey after the act of eating, thus next time Predators will be hungry, there will be less prey to eat, so some Predators will die The guy above is right, and we also have this written as he says in our school documents. - delta * Y More predators you have, less food they get, leading to decrease in predators after time as they have insufficient food If your equations were right and lets say we talk about wolves and sheep, wolves would eventually eat out all the sheep, gets overpopulated and then they would all die because they would have eaten all the sheep before, but this is not how it works. Both populations amounts are correlated.
@@spellweavergeneziso Thank you for the clarification of the question. Yes you are right, the equation could be written as -delta * Y. But I did not assume that delta would be a positive constant, it could be negative in the equation that I wrote. This is a good discussion, and I thank you both for pointing this out. You are both correct that if the predator had a positive rate of growth as a function of its size it will overpopulate.
@@EndlessEngineering aha this is so funny, dude just admit ur wrong. If u didn't assume that the constants were positive why would u bother making the rate of deaths in the prey equation negative.
Is there a way to create a function based on what happens when the predator reaches a carrying capacity due to competition for remaining prey and disease? Is there a way to adapt these more simplified functions to model that regulation?
Hey Emily. I am not aware of a method to do that, but I imagine it would be through building a model of how the rate of predation (encounter) changes in events like disease and other factors

Hi Kadem, Thanks for your comment. The goal of this video was just to show how modeling can take on different forms, upcoming videos will deal with examples on systems that behave like this one or in a similar way.
Hell yah I'm gonna hit the thumb up. You explained way better in 8 min than my Differential Equations teacher did in 18 min. Thanks
Thanks for watching! Glad you found the video useful
YOU are writing BACKWARDS.... Impressive!
i believe he did a normal writing which issss backword to us but normal to him then mirrored it from middle line then it looks normal to us
@@xornchaoroy4613 But if that were true, then the writing would be on the left side of the screen and not the right one, correct?
i know Im kinda off topic but do anybody know a good place to stream newly released movies online?
@Gabriel Jordan Try flixzone. Just google for it =)
@Gabriel Jordan I would suggest Flixzone. You can find it on google =)
Very well-explained. Thanks for sharing, brother.
Thank you for watching! Glad you found it useful
Just what I need and you deliver, man you are brilliant!
can you explain in more details exactly what the different constants represent? i didnt quite understand that part

doing god's work, THANK YOU
Thanks for watching! Glad you found it useful
Really amazing explanation.
The delta factor must be negative sign. Otherwise how will it depict decreasing predator population when prey = 0?
This is a case that for here in the abscence of another both increase exponentially

More predators you have, less food they get, leading to decrease in predators after time as they have insufficient food

For interactions why we use x.y why we not like as x.y^2,x^2.y ...etc

감사합니다.
good job 👍🏼

the predator equation is in opposite: xy - y
I wish you made an example about system that behaves like that
