BIODIVERSITY & calculating INDEX of DIVERSITY. Human impact and definitions for A-Level Biology

[@yusufi1962]

Hey I just finished all your Year 1 content. Its really helped me to absorb and retain the content. Ive also noticed that you actively respond to all your students comments and cater for any requests they have. Its awfully kind of you and I hope they appreciate it. On their behalf and mine, your videos have helped us greatly. Thank you !!

[@MissEstruchBiology]

Awww thank you! Really pleased you are finding all the videos so helpful 😀

[@bval4365]

one hour until my year 1 mock exam and i feel like ive learnt more from this playlist than what my teachers have taught in the past year so THANKS!!!

[@madooha8966]

Really glad I found your channel your videos are so helpful simple and to the point I also love that you address topics in biology that many people over look such as how to interpret statistics in biology looking forward to more content 🙌

[@MissEstruchBiology]

So glad to hear you are finding the videos helpful. How did you find my channel? Let me know if you have any content requests.

[@madooha8966]

Miss Estruch I found your channel through a quick KZbin search for a specific topic I will definitely be sharing with my friends also I’m a year 12 student and recently we’ve started year 13 content for aqa starting with photosynthesis so maybe some more year 13 based content would be good as I’m a little worried about learning the new content by myself I know year 13 content is a little on the heavy side 😬 especially because we don’t have the textbooks either to have something to refer to when trying to learn. thank you for asking x

[@MissEstruchBiology]

Hello, I few people have mentioned they are now on Photosynthesis so I will pump this higher up the priority list. I do have a photosynthesis required practical and respiration, when you get onto that bit. I will try my best to get some thing on LDR and LIR up within the fortnight

[@samanthamurillo247]

Thanks for this! I am currently writing a lab report and came across your video as I need to know how to compute for the diversity index. The explanation is very simple but easy to understand. The table also helps.

[@MissEstruchBiology]

Good luck with your lap report. Glad it has helped 😊😊

[@AM-hn7gj]

Hi, do you have a video for 3.4.7 investigating diversity?

[@mhasanp196]

Thank you sooo much. I love how your videos are concise and easy to understand. I now understand how to use the index of diversity formula.

[@MissEstruchBiology]

yay so pleased it helped 🙌

Thanks for the talk about Index of Diversity,Now i really now not confuse at that formula!

[@MissEstruchBiology]

Glad it helped 😚

[@HUVideoer]

The last part is also great for AS/A level marine science. thanks

[@MissEstruchBiology]

aww amazing , so pleased it fit that course too. Sounds an exciting A level!

Is there a video on standard deviation, which is part of the diversity content in Topic 4?

[@rahulsangha8908]

haha awww so happy my videos are helping you

[@akuawinnie9957]

Hello, 2:9 would you suggest that we remember all of the farming techniques along with their compromises or is it sufficient to just remember 2-3?

[@MissEstruchBiology]

2 or 3 should be fine, it may be more application based questions linked to this

[@akuawinnie9957]

@@MissEstruchBiology ok thanks ☺

[@sarimiari1389]

Great videos, but wish that you organise the playlist in the same order as the text-book

[@MissEstruchBiology]

Glad they help you! I will get onto changing the order according to common teaching order (each textbook will have slightly different order)

[@MissEstruchBiology]

All reorganised :D Hope that helps with your studies, and thanks for the feedback.

thank you so much you're the best for making these videos! and your are very beautiful by the way!

Thank you so much lockdown online learning had me confused now I understand

[@MissEstruchBiology]

So glad you're feeling more confident now during online learning!!

[@uwotm8770]

hi miss thanks for the video, i just wanted to ask if you could please clarify the species definition in many textbooks, where it says "a species is a group of organisms that can interbreed and produce fertile offspring" - doesn't interbreeding mean organisms from different species breeding together and doesn't that then produce infertile offspring? it doesn't make any sense

[@uwotm8770]

i thought inbreed was the correct term to use for breeding within the same species

[@MissEstruchBiology]

Hello, inbreed is breeding within the same family. Interbreeding is between the difference races of species. I know what you are saying, I don't like the use of 'interbreed' as that often means between different species. I phrase it as 'when individuals breed to create fertile offspring' instead.

do we need to know SIMPSONS index of diversity? its different...

[@MissEstruchBiology]

the formula used in this video is the one that is from the AQA specification to use

[@PatriciaChoufani]

@@MissEstruchBiology okay thank you

[@FemboyEconomics1]

Why have you done the calculation upside down?

[@MissEstruchBiology]

At which point? The formula given here is the one stated in the AQA specification

[@FemboyEconomics1]

@@MissEstruchBiology In class we are given D= 1 - (sigma n(n-1) / N(N-1))

[@yusufi1962]

It may be good use for some students if you would walk through some practice questions going through each topic and talking us through how to answer them and where the marks are given. 🤷🏽‍♂️

[@MissEstruchBiology]

Good idea! So far I've just done this for skill based but I could do it by topic 😊

[@hs6585]

Yess pls! 😅

[@abrahamadeyemi5484]

Keep it up

[@MissEstruchBiology]

thank you

[@MakueiDuteJothdit]

It's more understandable

[@JDennison-u3d]

Formula is upside down? Index of diversity should be an answer between 0 and 1. this example the answer should be 180/600 = 0.3! Not 3.3

[@MissEstruchBiology]

Not for Simpsons index of diversity, there are different formula out there, but this is what AQA state
