The colonization of an island habitat is when a species not previously from that island, migrates to that island, and inhabits it. The further the island from the mainland, the lower the species diversity. This happens because the closer the island is to the mainland, the easier it is for species to travel to it, and so more species can, but as we look at further islands, fewer and fewer species are capable of traveling large distances to colonize them, and so there is less species diversity.
The relationship displayed by the graph at 5:00 is described as being very linear. It is not. This graph uses a log scale on both axes. Each increment is 10x the previous increment. 1, 10, 100, 1000, etc. Log-log graphs are used to find the exponent of power functions like y = Ax^k. The slope of the graph gives you the power, this graph has a slope of less than one, so the graph would be upwards sloping, and downwards curving, similar to a square root function. The graph has to flatten out as island size increases because there is a limit to the number of unique new niches you can add with increasing size.
Good catch and great explanation of a log based scale! I should have only described island size and number of species as having a direct relationship, not a linear one.
Hey Mr. Smedes! Thanks for the video. How would you have answered part (A) of the practice FRQ? Just want something to look off of as I score my own response. Thanks once again!
Hi your vids are always so gooood, a piece of feedback is to make it more simple because im a freshman doing APES and theres lots of vocab i dont know haha
when you say mainland, do you mean the biggest island between a whole bunch, like the best one or most successful? Or does it have a different meaning?

Mr Smedes you truly are the Greatest of all time thank you for helping me pass
Oh my god!!! These videos are saving my life!!! I love you man!!!!

I'm going to touch you
Omg these videos are literally saving my life ! You explain so well! Just what I needed . Thanks .
Great video! really well explained - currently studying for my apes final. (came from searching the topic up)
@@Mr.Smedes all multiple choice, however, our unit tests typically have an frq portion and a multiple choice section
MR SMEDES UR THE GOAT TYSM

For part A the answer would be
Your slides make the class so much easier. but where can I get the slides?

I’m a senior and I still don’t understand the vocab😭
when you say mainland, do you mean the biggest island between a whole bunch, like the best one or most successful? Or does it have a different meaning?
very useful thank you!
Do we need to know the different zones on the island like arid zone, transition zone etc.
A very big thanq
My mama hates me
same
😢
kind of random to say.
:(
