How are Shannon Wiener values used in the Wilcoxon rank sum test?

I have six ecosystems in two substrate categories (Triplicates essentially). I have determined shannon wiener index values for each ecosystem and also for the two categories separately. I have done this for two separate sets of data that were sampled in two separate years. Is it possible to statistically compare the development of the biodiversity between each of the categories i.e., the development of biodiveristy in ecosystem 1 between the two years, using the shannon wiener values somehow? Are there any other tests that could work? I am aware of the hutcheson t test however, some of my data is not normally distributed.

I would really appreciate some help!

I have 6 ecosystems, 3 of which are substrate A and the other 3 are substrate B. each ecosystem has about 10 species. I have calculated a simpsons value for each ecosystem and a simpsons value for each substrate. I would like to statistically compare the two index values of substrate A and B, is this possible in any way? Since I would like to statistically compare the biodiversity between the two substrates, what is the best way to go about this?

I have the data of every avian species I saw at 38 study sites within one month, to calculate the biodiversity of each study site should I use Simpsons index or Shannons Index? or another one?

I was wondering if you could suggest how to analyze insect community (multivariate) data collected across multiple sites and time points. Specifically, I aim to assess differences in community composition between Treatment and Control conditions.

What are my options regarding:

I’m aware of Multivariate Time Series analysis applied in fields like Finance and likely many other approaches that could be relevant. However, I am struggling to determine the most appropriate method for my case.

If you have experience in this area or can recommend a good blog, tutorial, or resource, I would greatly appreciate your suggestions.

Thank you for your time!

Any answer my question

Dear,

Normally the Shannon-Weaver index and Simpson index are correlated.

However, in my study on the diversity of 2 bacterial communities following results were obtained.

Shannon-Weaver index:

X: 2.72

Y: 2.83

Inverse Simpson index:

X: 5.50

Y: 8.14

My question is if these results are plausible, or should I not trust them?

Kind regards

Ecosystem Services (Elsevier) is open to receive proposals for new innovative Special Issues. Ecosystem Services is a high rank journal, among the 15 best in environmental sciences (6.1 impact factor 2023), ranked Q1. Our position gives high visibility to the articles we publish.

Special Issues are articles collections (12 or more) that share well-defined, scientifically innovative and coherent aims and scope. For an overview of present and past SI please visit the journal's webpage.

If you are interested in proposing an appealing and high-quality topic for a special issue in Ecosystem Services journal, please send to me a one-page description of the SI aims and scope, including the team of guest editors (3-5). We will carefully assess the proposal in terms of scientific quality and aims and scope. The scope has to be clear around a framing conceptual outlining that gathers together an article collection with sufficient coherence.

Looking forward to hearing from you!

I'd like to run a Habitat Suitability Model (HSM) for seagrass in Scotland using Maxent. I have ~30 years of presence data and yearly averages for temperature and salinity. I'd like to try to match the presence points to this yearly environmental data (i.e. samples from 1999 use yearly environmental data from 1999, and samples from 2005 use yearly environmental data from 2005). Is this possible? I'll be running the code in R so any links to code/tutorials that do this would be appreciated.
