Becoming A Master – Alpha Diversity


Week 30

Hello friends! This week I have been all about the alpha diversity statistics so I thought I would tell you about how and why I’m doing it. Alpha biodiversity is effectively a way of working out the biodiversity in a local area. This can be done within a quadrat or within sections of a transect. For my dissertation I am looking at the alpha biodiversity of each of my hedgerows in my study.

To do this I’m using some software called EstimateS and I put in my results and then it uses different formula to find different alpha biodiversity scores. There can be different scores as lots of different studies have developed different mathematical formula to work out the biodiversity. Each formula is more effective for different types of study. For example a study looking at insect species richness may find a different formula gives a more accurate representation of alpha biodiversity than a study looking at salt marsh plants. I have four different formula to choose from and hopefully by next week I will have settled on one to use.

It’s been another heavy computer week but I did head home to Cornwall this weekend (why this blog is a little late) to run around the fields and check up on my hedgerows.

Hope you’ve enjoyed this little update and a little lesson on statistics!
