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.

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.

Species distribution models have limited spatial transferability for invasive species.

open access: yesEcology Letters, 2020
The reliability of transferring species distribution models (SDMs) to new ranges and future climates has been widely debated. Biological invasions offer the unique opportunity to evaluate model transferability, as distribution data between species ...

Understanding drivers of species distribution change: a trait-based approach [PDF]

open access: yes, 2013
The impacts of anthropogenic environmental change on biodiversity are well documented, with threats such as habitat loss and climate change identified as causes of change in species distributions.

Used-habitat calibration plots: a new procedure for validating species distribution, resource selection, and step-selection models [PDF]

open access: yes, 2018
“Species distribution modeling” was recently ranked as one of the top five “research fronts” in ecology and the environmental sciences by ISI's Essential Science Indicators (Renner and Warton 2013), reflecting the importance of predicting how species ...

Modelling species distributions using regression quantiles [PDF]

open access: yesJournal of Applied Ecology, 2007
Summary Species distribution modelling is an important and well‐established tool for conservation planning and resource management. Modelling techniques based on central estimates of species responses to environmental factors do not always provide ecologically meaningful estimates of species–environment relationships and are being increasingly ...

Distribution modelling of the endangered spotted Greenshank (Tringa guttifer) in a key area within its winter range

open access: yesGlobal Ecology and Conservation, 2020
The Spotted Greenshank (Tringa guttifer) is one of the most threated shorebird species in the world, but key environmental characteristics associated with its presence are still not well understood. Here we summarised historical records and recent survey

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 ...

The Role of Behavioral Dynamics in Determining the Patch Distributions of Interacting Species [PDF]

open access: yes, 2007
The effect of the behavioral dynamics of movement on the population dynamics of interacting species in multipatch systems is studied. The behavioral dynamics of habitat choice used in a range of previous models are reviewed.

A theoretical framework for upscaling species distribution models

open access: yesMethods in Ecology and Evolution, 2023
Species distribution models (SDM) have become one of the most popular predictive tools in ecology. With the advent of new computation and remote sensing technology, high‐resolution environmental data sets are becoming more and more common predictors in ...
