Good Day R-Sig-Geo Friends, I am interested in testing whether sister species pairs (species with trait A vs species with trait B) have significant differences in niche breadth.
To do this, I have generated for each species pair 100 Maxent bootstrap replicates. For each of these replicates I have calculated the niche breadth using Levins' B from ENMTools. Now I would like to use these values for a significance test. Is it incorrect to use a t-test to look for difference between species pairs due to the lack of independence of the replicates? Is it better to use a nonparametric test? If so, why and what should the sample size be and which test? Finally, I am also interested to know whether groups of species with trait A and groups of species with trait B have differences in niche breadth. Using the same data above, what is the most appropriate statistical test and appropriate sample size? Sample data: species A species B0.168581128 0.0924769420.138468258 0.0975361750.16412658 0.1076619820.16371685 0.1032603730.162732326 0.1217574970.129050784 0.1130964890.126583781 0.1149817320.176855441 0.0993640140.257605323 0.1037768860.182453389 0.1082939280.175081388 0.106879389 Thanks for reading and I am very interested to know your suggestions.
