    Controlling the influence of variation in a factor

    I sampled communities in different habitats along a continental margin. Depth is a strong structuring factor in the ocean. To mitigate or control the influence of the depth factor and in a comparison of habitats, would it make more sense to perform a 2-way ANOVA with with depth as random or an...

Sampling was conducted on 5 sites along 1 transect (~ 500 - 2200 m), 5 sites on another transect (~500 - 1800 m), and 3 sites on another transect (~ 770 - 1000...

    I am trying to run a taxonomic distinctness analysis and I keep encountering a data inconsistency error. After running a check, the program tells me what data cells are inconsistent in my aggregation file. But when I review those cells, I do not see what the problem is. Is there anyone available...
