Niche conservation in copepods between ocean basins

This dataset provides the necessary data to test for niche conservatism as demonstrated in the article \"Niche conservatism in copepods between ocean basins; 10.1111/ecog.05690\". 

Our study examined niche conservatism (i.e. a species' niche remains stable in space and time) between populations of the same species of marine copepod in different ocean basins. We used two approaches to test for niche conservatism which can be defined as a Princpial Component Analysis (PCA) and Environmental Niche Model (ENM) method. Niches may differ by virtue of the fact that the available environmental conditions do not overlap. This can be addressed by first establishing a baseline or a null model that quantifies how far a niche would be expected to differ by chance based on the environmental conditions in both areas. We used six environmental variables to define the environmental niche (sea surface temperature - SST °C, Salinity, mixed layer depth - MLD (m), bathymetric depth (m), chlorophyll-a - chl...
