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 BiologyGlobal hotspots for marine debris ingestion by sea turtles

Plastic pollution has rapidly become one of the major threats to global marine conservation. Nearly 700 species are at risk from ingestion and entanglement, and sea turtles are among the most heavily impacted species. We conducted a risk assessment to determine which factors are most relevant in predicting plastic ingestion by sea turtles, and in which geographic regions sea turtle populations are most at risk. We found hot spots of high risk to turtles, and discovered that this risk is increasing over time. Young, oceanic turtles and olive ridley turtles are most at risk of plastic ingestion.

Global Change BiologyBiotic homogenization due to urbanization

Urbanization is one of the major current land-use changes in many parts of the world. Since 2008 more than 50% of human population is cities. It is thus very likely that urbanization has a major impact on biodiversity. Yet, the consequences of urbanization for insect diversity are poorly understood. The study shows, that from city to city one finds similar insect species, whereas from rural area to rural area the composition of insect species changes more, in particular of specialist species. This shows that on a large scale urbanization leads to a loss of biodiversity.

Global Change BiologyCO2 mitigates the impact of heat on coffee

It is believed that the coffee crop is threatened by the predicted global warming conditions, but it is virtually unknown how the coffee plant responds to the interaction of high air [CO2] and temperature. It was herein demonstrated that elevated [CO2] mitigates the impact of heat via a global strengthening of the carbon assimilatory machinery. Therefore, predictions concerning the impacts of climate change scenarios on the coffee crop should consider the role of CO2 as a key player in heat tolerance, and future perspectives on the sustainability of the coffee crop should not be as catastrophic as previously predicted.
