Here are my data:
A) 9 different creeks.
B) 3 different treatments (Intensively grazed, Extensively grazed, Ungrazed)
C) Sampling: fish, insects, "crabs & shrimp" (let's call this group shellfish) and benthos
D) There are 3 creeks for each treatment.
E) All samples are from one event.
a) Fish (one catch/creek).
b) Insects (6 traps/creek).
c) Shellfish (one catch/creek).
d) Benthos (3 samples/creek)
I want to examine if the treatment influences the diversity for each sampled group as for the totality of all groups. I want to use the Shannon Diversity Index, abundance and richness.
What steps should I follow in R to accomplish this? I would really appreciate a step-by-step approach since I am very new to R.
Thank you for any imput!!!
So far I only know that I will need the "BiodiversityR" package. I would need step-by-step instructions.
