To understand the impact of data sampling biases and quality concerns in global-scale models, this team used all available GBIF-mediated data for fish species from marine-only orders to compare four common procedures. Their findings suggest that, as long as researchers clean the original data, correct for autocorrelation and account for obvious underestimations in species richness, the work of improving both data quantity and quality may matter more in accurately predicting distributions than the development of sophisticated mathematical models.
Clean global data may matter more than complex models
This study suggests that simple data cleaning and correction may improve modeled distribution predictions more than developing sophisticated mathematical models.
