Testing the accuracy of species distribution models using species records from a new field survey

Species distribution models are a very popular tool in ecology and biogeography and have great potential to help direct conservation efforts. Models are traditionally tested by using half the original species records to build the model and half to …

Biodiversity economics: the value of pollination services to Egypt

Pollinator populations are under severe pressure worldwide because of man-made intensification in land use, including the use of pesticides and fertilizers. The majority of wild and crop plants are fully or partially dependent on pollinators for …

Climate-based models of spatial patterns of species richness in Egypt’s butterfly and mammal fauna

Aim: Identifying areas of high species richness is an important goal of conservation biogeography. In this study we compared alternative methods for generating climate-based estimates of spatial patterns of butterfly and mammal species richness. …

Effect of characteristics of butterfly species on the accuracy of distribution models in an arid environment

Species distribution models show great promise as tools for conservation ecology. However, their accuracy has been shown to vary widely among taxa. There is some evidence that this variation is partly owing to ecological differences among species, …
