Taxonomic Distinctness of Demersal Fishes of the California Current: Moving Beyond Simple Measures of Diversity for Marine Ecosystem-Based Management
Figure 5
Taxonomic distinctness versus depth for different latitude zones.
(A–D) AvTD and (E–H) VarTD. Latitude zone given in panes (A–D) corresponds with panes (E–H). Data were analyzed with Generalized Additive Models. Solid lines represent the smoothed trend. Broken lines are ±1 s.e. The data points shown are the residuals around the smoothed term. The y-axis is the smoothed parameter and its estimated degrees of freedom from the GAM. * = p<0.05, ** = p<0.01, *** = p<0.001.
