Aim The area under the receiver operating characteristic (ROC) curve (AUC) is a widely
used statistic for assessing the discriminatory capacity of species distribution models. Here, I …

Ecological niche models represent key tools in biogeography but the effects of biased
sampling hinder their use. Here, we address the utility of two forms of filtering the calibration …

It is thought that species abundance is correlated with environmental suitability and that
environmental variables, scale, and type of model fitting can confound this relationship. We …

Species distribution models (SDM) are commonly used to obtain hypotheses on either the
realized or the potential distribution of species. The reliability and meaning of these …

Abstract Aim Species distribution models (SDMs) have emerged as essential tools in the
equipment of many ecologists, useful to explore species distributions in space and time and …

The need to understand the processes sha** population distributions has resulted in a
vast increase in the diversity of spatial wildlife data, leading to the development of many …

The wild boar is an important crop raider as well as a reservoir and agent of spread of swine
diseases. Due to increasing densities and expanding ranges worldwide, the related …

Aim Intercomparison of mechanistic and empirical models is an important step towards
improving projections of potential species distribution and abundance. We aim to compare …

Abstract Aims:(1) To present a statistically based classification of Azorean natural zonal
vegetation;(2) to characterize the main features of this vegetation and (3) to present the first …

Oceanic islands host a high proportion of the world's endemic species. Many such species
are at risk of extinction owing to habitat degradation and loss, biological invasions and other …
