Aims and Scope

More information

Global Change Biology exists to promote understanding of the interface between all aspects of current environmental change that affects a substantial part of the globe and biological systems.

The journal publishes primary research articles, technical advances, research reviews, commentaries and letters.

Global Change Biology defines global change as any consistent trend in the environment - past, present or projected - that affects a substantial part of the globe. Examples include:

Southern Oceans and Climate Change Southern Oceans and Climate Change

This invited article by Andrew J. Constable and coauthors reviews changes in Southern Ocean habitats, the direct effects those changes will have on marine life and priorities for future work. Habitats will not change uniformly around the continent, particularly sea-ice. Those lower on the food chain are expected to move south. The northern extent of Antarctic krill and finfish will depend on their tolerance to warming oceans and changes to productivity. Ocean acidification will negatively affect calcifying organisms, as well as Antarctic krill. Marine mammals and birds may be affected by changes in the location of food.


Methane Emissions from Amazonian RiversMethane Emissions from Amazonian Rivers

Methane is an important greenhouse gas and we know little about its natural emission from rivers to the atmosphere. Henrique O. Sawakuchi and coauthors show the results of fluxes between water and air, measured with static chambers deployed in the Amazon mainstem and its major tributaries during both high and low water seasons. The measurements indicate that the Amazon alone releases to the atmosphere significant amounts of methane -corresponding to 22-28% of the global river methane emissions- much higher than previous estimates.

High Altitude Competition for Habitat High-altitude Competition for Habitat

In mountainous regions, climate change is forcing many animal populations to higher elevations where it is cooler. Tom H.E. Mason and his coauthors show that Alpine chamois, a species of mountain goat-antelope, can avoid moving to higher altitudes by spending less time feeding when it is hotter. However, the presence of domestic sheep – which compete with chamois for food – pushes chamois to much higher elevations, where their habitat is scarcer. Thus, the effects of interactions with competing species outweigh those expected from future climate change. Appropriate management of livestock might mitigate for climate change impacts on this and similar species.
