I am trying to identify the subset of non-gelatinous zooplankton species that show correlation with jellyfish species. I have abundance data for
non-gelatinous zooplankton species. While the jellyfish data are presence-absence data.
I am wondering how I can run a forward selection process in Canoco 5 to do so?
Any help would be highly appreciated.
I think that if you have no data of jellyfish, you can't reveal that zooplankton related with jellyfish species. And if you want to research zooplankton relationship with jellyfish, you just need run pearson analyse with spss
If you convert your zooplankton abundance data to presence-absence, then you can correlate it with jellyfish data to see if there is a relationship. If there is zero abundance, then the species is absent. If abundance is > 0, then the species is present. Then you can see if the zooplankton are associated with the jellyfish :)
Dear Andrew, Thanks for your guidance. I am still wondering which of methods in Canoco5 should be employed to do so.
You are welcome. You could just do the Pearson correlation as Chengxue Ma recommended :)
Canoco 5.0 is a good and easy program to be used in studies aimed at assessing functional trends among communities.
we have recently publish a paper in Agriculture, Ecosystems and Environment in which CANOCO 5.0 was used. Although the study was addreced to develov a theorical response-effect trait framework, if you check the MM section you can check how CANOCO 5.0 was used
