Journal ArticleDOI

Very high resolution interpolated climate surfaces for global land areas.

TL;DR: In this paper, the authors developed interpolated climate surfaces for global land areas (excluding Antarctica) at a spatial resolution of 30 arc s (often referred to as 1-km spatial resolution).
Journal ArticleDOI

WorldClim 2: new 1-km spatial resolution climate surfaces for global land areas

TL;DR: In this paper, the authors created a new dataset of spatially interpolated monthly climate data for global land areas at a very high spatial resolution (approximately 1 km2), including monthly temperature (minimum, maximum and average), precipitation, solar radiation, vapour pressure and wind speed, aggregated across a target temporal range of 1970-2000, using data from between 9000 and 60,000 weather stations.
Journal ArticleDOI

Effects of sample size on the performance of species distribution models

TL;DR: In this article, a broad suite of algorithms with independent presence-absence data from multiple species and regions were evaluated for 46 species (from six different regions of the world) at three sample sizes (100, 30 and 10 records).
Journal ArticleDOI

The ability of climate envelope models to predict the effect of climate change on species distributions

TL;DR: This article evaluated the ability of CEMs to predict species distributions under different climates by comparing their predictions with those obtained with a mechanistic model (MM), in which the distribution of a species is modeled based on knowledge of the species' physiology and the potential distributions of 100 plant species were modeled with an MM for current conditions, a past climate reconstruction (21000 years before present) and a future climate projection (double preindustrial CO2 conditions).
