AS Biology - Biodiversity and sampling OVERVIEW (OCR A Chapters 11.1-5)

Ch.11 Biodiversity can be largely split into two halves: 11.1-5 and 11.6-8. This video covers the first half, focusing on the different types of biodiversity and sampling techniques. For details, you can refer to the chapter number that is written next to the different "bubbles" on the mind map.

***Please keep in mind that this is an overview where I covered the most important points within the chapters. I do recommend reading through the textbook after watching the video to ensure you've really understood the content well. For some parts, I've selected some key examples to illustrate and elaborate, as this chapter is extremely wordy, I've opted for a slightly smarter way of studying, which is to pick some examples to learn well and just be aware of the rest to save "memory space" in my brain...***

[roxers]

it isn't a line transect at 14:50 it should be a belt transect.

[elinakoulias]

hi, i don’t think you have to learn the simpson index equation, i think it is provided. please can you confirm this?

[ddd]

Just to clarify, at 14:41 isn't the sampling method described an interrupted belt transect - as opposed to a line transect?
