Beyond a Climate-Centric View of Plant Distribution: Edaphic Variables Add Value to Distribution Models

Beyond a Climate-Centric View of Plant Distribution: Edaphic Variables Add Value to Distribution Models

Both climatic and edaphic conditions determine plant distribution, however many species distribution models do not include edaphic variables especially over large geographical extent. Using an exceptional database of vegetation plots (n = 4839) covering an extent of ∼55,000 km2, we tested whether the inclusion of fine scale edaphic variables would improve model predictions of plant distribution...

Plant Phenology And Distribution In Relation To Recent Climate Change

Seductive Simulations? Uncertainty Distribution Around Climate Models

This paper discusses the distribution of certainty around General Circulation Models (GCMs) – computer models used to project possible global climatic changes due to human emissions of greenhouse gases. It examines the trope of distance underpinning Donald MacKenzie’s concept of ‘certainty trough’, and calls for a more multi-dimensional and dynamic conceptualization of how uncertainty is distri...

A simple post-hoc method to add spatial context to predictive species distribution models

Methods to incorporate spatial context into species distribution models (SDMs) are underutilised, with predictions usually based only on environmental space and ignoring geographic space. The goals of this study were to demonstrate a relatively simple post-hoc method to include spatial context in SDMs and to quantify the improvement over purely niche-based models. The method involved producing ...

Aspects of Value Distribution Theory in Several Complex Variables

BY WILHELM STOLL During the last fifty years value distribution in one complex variable has been established as one of the most beautiful branches of complex analysis. In several variables, value distribution was slow to grow up. Only a few people were concerned and many obstacles had to be overcome. However, recently, the theory has gained wide recognition. The outlook for the future is bright...
