Potential changes in the distribution of Carnegiea gigantea under future scenarios [PDF]

open access: yesPeerJ, 2018
Over the last decades several studies have identified that the directional changes in climate induced by anthropogenic emissions of greenhouse gases are affecting the ecology of desert ecosystems.

blockCV: an R package for generating spatially or environmentally separated folds for k-fold cross-validation of species distribution models

open access: yesbioRxiv, 2018
When applied to structured data, conventional random cross-validation techniques can lead to underestimation of prediction error, and may result in inappropriate model selection.

A problem with variable selection in a comparison of correlative and process‐based species distribution models: Comments on Higgins et al., 2020

open access: yesEcology and Evolution, 2021
Comments are presented on an article published in October 2020 in Ecology and Evolution (“Predictive ability of a process‐based versus a correlative species distribution model”) by Higgins et al. This analyzed natural distributions of Australian eucalypt

Clustering Species With Residual Covariance Matrix in Joint Species Distribution Models

open access: yesFrontiers in Ecology and Evolution, 2021
Modeling species distributions over space and time is one of the major research topics in both ecology and conservation biology. Joint Species Distribution models (JSDMs) have recently been introduced as a tool to better model community data, by ...

Multi-Scenario Species Distribution Modeling [PDF]

open access: yesInsects, 2019
Correlative species distribution models (SDMs) are increasingly being used to predict suitable insect habitats. There is also much criticism of prediction discrepancies among different SDMs for the same species and the lack of effective communication about SDM prediction uncertainty.

Delineating generalized species boundaries from species distribution data and a species distribution model [PDF]

open access: yesInternational Journal of Geographical Information Science, 2013
Species distribution models (SDM) are commonly used to provide information about species ranges or extents, and often are intended to represent the entire area of potential occupancy or suitable habitat in which individuals occur. While SDMs can provide results over various geographic extents, they normally operate within a grid and cannot delimit ...

Spatial Evaluation of Machine Learning-Based Species Distribution Models for Prediction of Invasive Ant Species Distribution

open access: yesApplied Sciences, 2022
Recent advances in species distribution models (SDMs) associated with artificial intelligence (AI) and increased volumes of available data for model variables have allowed reliable evaluation of the potential distribution of any species.

Dealing with overprediction in species distribution models: How adding distance constraints can improve model accuracy

open access: yes, 2020
Species distribution models can be affected by overprediction when dispersal movement is not incorporated into the modelling process. We compared the efficiency of seven methods that take into account spatial constraints to reduce overprediction when ...

A comprehensive evaluation of predictive performance of 33 species distribution models at species and community levels

open access: yesEcological Monographs, 2019
A large array of species distribution model (SDM) approaches has been developed for explaining and predicting the occurrences of individual species or species assemblages.

Potential distributional shifts in North America of allelopathic invasive plant species under climate change models

open access: yesPlant Diversity, 2022
Predictive studies play a crucial role in the study of biological invasions of terrestrial plants under possible climate change scenarios. Invasive species are recognized for their ability to modify soil microbial communities and influence ecosystem ...
