Virtual Issue: The Southern Hemisphere

Edited by Mike Hutchings, David Gibson and Richard Bardgett
JULY 2009

The editors of Journal of Ecology are pleased to present this Virtual Issue on The Southern Hemisphere in recognition of the 2009 10th International Congress in Ecology in Brisbane, Australia. This Virtual Issue is a selection of 20 papers published in Journal of Ecology over the last three years. All studies were either carried out by ecologists based in the southern hemisphere or were conducted in a southern hemisphere country, including Argentina, Australia, Chile, Gabon, New Zealand, South Africa and Tanzania. Topics range from studies of physiological stress, plant interactions, and population demography, to community and ecosystem dynamics. Important concepts of current interest include efforts to understand and predict invasive species, global patterns of plant form, and the effects of climate change on Antarctic mosses. While most of the studies are on vascular plants, others are on algae or fungi. It is clear that some of the most compelling and important ecological studies are being conducted today in the southern hemisphere, and many of these are published in Journal of Ecology.

The papers included in this Virtual Issue reflect the international scope and range of Journal of Ecology. The journal is the oldest ecological journal in the world, published continuously since 1913 by the British Ecological Society. The Journal of Ecology is truly one of most important ecological journals available, having an Impact Factor in 2008 of 4.260 and being ranked 17th of 124 ecological journals. Moreover, the Journal of Ecology was recently recognized by the Special Libraries Association as being in the top 100 most influential journals in Biology and Medicine in the last 100 years.

We invite you to read and share with colleagues the papers in this Virtual Issue, visit the journal website, consider taking out a subscription if you don’t have one already, and submit your best work to the journal for potential publication.
