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:

Global Change BiologyCarbon resilience of a neotropical forest

Highlight: Global changes may intensify fires in Amazonia by altering forest microclimate and fuel dynamics. To isolate the effects of fuel loads, the authors manipulated fine fuel loads in a fire experiment located in southeast Amazonia. They show that fine fuel load accumulation increased the likelihood of larger understory fires. However, they also show that increased fine fuel loads alone are unlikely to create threshold conditions for high-intensity, catastrophic fires during non-drought years, given that wood increment increased in response to the experimental fires.

Global Change BiologyOpen Access: Trends in ocean biogeochemistry

Climate change is affecting the ocean's biogeochemistry, such as its pH and oxygen levels. Detecting these changes is not simple. Part of the difficulty is that the climate change signal can be 'hidden' by the natural variability. To separate the signal from the noise needs long data records. But how long? And where are the effects most likely to be observed soonest? Here researchers assess where and for how long the ocean should be observed to detect climate change effects in ocean biogeochemistry.

Global Change BiologyParasites in the sheep and goat industry

Gastrointestinal helminth parasites (worms) are a major economic and welfare concern in the global sheep/goat industry. The immature worms outside the host are sensitive to temperature and moisture. Therefore climate change could alter future levels of infection and disease. A mathematical model was developed for the blood-feeding worm Haemonchus contortus to map potential infection levels in Europe based on different climate change scenarios. An increase in infection potential was predicted throughout Europe and an altered seasonal pattern of infection was predicted in northern Europe. This could affect the sustainability of sheep/goat farming if farmers are unable to adapt.
