Geographical Characteristic

Isolation is a fundamental geographical characteristic that plays an important role in invasion ecology. However, risk mapping for established non-native species currently tends to ignore isolation, and instead focuses on the risk of population growth through the use of species distribution models. By focusing on how geographical isolation can be used to improve invasive species risk assessments this paper aims to: (i) provide a brief review of how methods to quantify isolation have developed, (ii) describe least-cost modelling as one approach to quantify isolation, (iii) promote catchment area mapping as a method of continuous isolation mapping that can improve invasive species risk assessments that may currently only consider risk from population growth, and (iv) discuss ways in which geographical isolation could be modified to control invasive species.

And Control

Invasive species, those that are nonnative and cause economic damage, are one of the main threats to ecosystems around the world. Ambrosia beetles are some of the most common invasive insects. Currently, severe economic impacts have been increasingly reported for all the invasive shot hole borers in South Africa, California, Israel, and throughout Asia. This 7-page fact sheet written by Demian F. Gomez, Jiri Hulcr, and Daniel Carrillo and published by the School of Forest Resources and Conservation describes shot hole borers and their biology and hosts and lists some strategies for prevention and control of these pests. http://edis.ifas.ufl.edu/fr422
