I am looking at a test that would work with the data I have available and what would help assess my current hypothesis.
I have access to data of American mink (Neovison vison) and Eurasion otter (Lutra lutra), and potentially have data sets for prey species such as the European rabbit( Oryctolagus cuniculus ), and Water vole ( Arvicola amphibius ). These data sets vary in length, however are all long term data sets collected by a recording organisation that gains records through public, and experts confirming.
I also have access to habitat maps of the study area.
I'm trying to find a statistic test that I can use to assess if the American Mink have had a shift in habitat preference based on the increase of the Eurasian otter population.
I am also trying to find another statistic test to see if there is a relationship between the habitat of prey and predator.
Anyone able to help?
Hi Ethan Henderson look for test like presence or absence; linear regression and correlation tests. Try to organize a table that can relationship of the prey with the habitat and the presence of the predator. In the linear regression, you can atribute a number of individuals of the prey and predator and establish whether the number of the one this categories varies depending on the number of the other.
And you can do principle component analysis. But you must adjust the data for any bias such as differences in methodology or duration of study and try to obtain copyright, otherwise you could see the data published by someone else too
