Hello, I am trying to evaluate the functional diversity (FEve, Fdiv, Fdis) of a community of fish contrasting the data obtained in different years, my question is: the calculation of the indices can be done in the same data matrix and compare the data obtained or each year must be calculated individually and subsequently compare the results?
You must use the same single big data matrix, otherwise you will not capture interactions between year :)
Good question and good idea. Do you want to try your methods for tropical urban plant communities? Could you tell me your email address for more details if you like. Happy national day. Thanks.
Andrew Paul McKenzie Pegman Hello, thank you very much, my particular goal is to observe if there were differences in functional diversity over the years, not so much the interactions between the years.
Kechang Niu Hello, thank u,yes, my particular goal is to observe if there were differences in functional diversity over the years
Artëm Sozontov Hello, thank you very much for the answer, yes, I have a base of traits (ecomorphological and ecological) and abundances for all the sp found in the years of sampling (in each year it was collected in 3 different months and in each collection there were 4 points of sampling), and I am just trying to contrast if there were differences in functional diversity throughout these years.
Carlos Blas over the years is the same as between years. Both terms compare years. Your question said you wanted to compare years. You need all the data in the same file so you include all interactions between years
Yes, it is a Beta delta-time comparison. It is crucial that the methodology that you use to get your data in each year is entirely the same. Nice question!
