From a statistical point of view, we interpret the data as a marked point pattern, where the sampling locations form a point pattern and the measurements taken in those locations (i.e., species abundance or occur‐ rence) are the associated marks. Inference and prediction of species distribution is performed using a Bayesian approach, and integrated nested Laplace approximation (INLA) methodology and software are used for model fitting to minimize the compu‐ tational burden. We show that abundance is highly overestimated at low abundance locations when preferential sampling effects not accounted for, in both a simulated example and a practical application using fishery data. This highlights that ecologists should be aware of the potential bias resulting from preferential sampling and ac‐ count for it in a model when a survey is based on non‐randomized and/or non‐sys‐ tematic sampling. | Versión del editor: | https://doi.org/10.1002/ece3.4789 | URI: | http://hdl.handle.net/10261/326373 | DOI: | 10.1002/ece3.4789 | ISSN: | 2045-7758 |
