TLDR
In this article, the authors address the question of whether incorporating spatial autocorrelation (SAC) in data affects estimates of model coefficients and inference from statistical models, and show that these biased estimates and incorrect model specifications have implications for predicting species occurrences under changing environmental conditions.Abstract:
Aim Spatial autocorrelation (SAC) in data, i.e. the higher similarity of closer samples, is a common phenomenon in ecology. SAC is starting to be considered in the analysis of species distribution data, and over the last 10 years several studies have incorporated SAC into statistical models (here termed ‘spatial models’). Here, I address the question of whether incorporating SAC affects estimates of model coefficients and inference from statistical models.
Methods I review ecological studies that compare spatial and non-spatial models.
Results In all cases coefficient estimates for environmental correlates of species distributions were affected by SAC, leading to a mis-estimation of on average c. 25%. Model fit was also improved by incorporating SAC.
Main conclusions These biased estimates and incorrect model specifications have implications for predicting species occurrences under changing environmental conditions. Spatial models are therefore required to estimate correctly the effects of environmental drivers on species present distributions, for a statistically unbiased identification of the drivers of distribution, and hence for more accurate forecasts of future distributions.read more

TL;DR: In this paper, the authors describe six different statistical approaches to infer correlates of species distributions, for both presence/absence (binary response) and species abundance data (poisson or normally distributed response), while accounting for spatial autocorrelation in model residuals: autocovariate regression; spatial eigenvector mapping; generalised least squares; (conditional and simultaneous) autoregressive models and generalised estimating equations.

TL;DR: In this article, the performance of three different simultaneous autoregressive (SAR) model types (spatial error = SAR err, lagged = SAR lag and mixed = SAR mix ) and common ordinary least squares (OLS) regression when accounting for spatial autocorrelation in species distribution data using four artificial data sets with known (but different) spatial auto-correlation structures.

TL;DR: It is shown that low-velocity areas are essential refuges for Earth’s many small-ranged species and the association between endemism and velocity was weakest in the highly vagile birds and strongest in the weakly dispersing amphibians, linking dispersal ability to extinction risk due to climate change.

Habitat Suitability and Distribution Models
TL;DR: In this article, the authors introduce the key stages of niche-based habitat suitability model building, evaluation and prediction required for understanding and predicting future patterns of species and biodiversity, including the main theory behind ecological niches and species distributions.
Journal ArticleDOI
Regression analysis of spatial data
TL;DR: The issues that need consideration when analysing spatial data are described and illustrated using simulation studies and the simulation-based approach provides much stronger evidence for comparative analysis than assessments based on single or small numbers of data sets.

TL;DR: This work compared 16 modelling methods over 226 species from 6 regions of the world, creating the most comprehensive set of model comparisons to date and found that presence-only data were effective for modelling species' distributions for many species and regions.
