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:

Distribution shifts of 2 woody speciesDistribution shifts of two woody species

Changes in global climate are altering ecological conditions for many species, and its consequences are typically most evident at the very edge in distribution of a species, where range expansions or contractions may occur. Luis Matías and Alistair Jump studied differences in the demography, growth, reproduction investment and herbivory damage of Scots pine and Common juniper populations through altitudinal and latitudinal gradients covering their complete distribution range. Populations at the lowermost altitude presented older individuals, higher mortality, decreased growth and lower reproduction than at the upper limit. This trend was maintained across latitude, suggesting an upland and northern displacement of the studied species.

Heat waves alter community structureHeat waves alter community structure

Gang Ma and coauthors used laboratory and field experiments, analysis of field observations, and a meta-analysis to determine how extreme events influence the structure of natural communities. Using aphids, their results indicate that changes in frequency and intensity of extreme high temperatures can alter the structure of natural communities over time, and that these changes are driven by a multitude of varying responses of species to high temperatures. They highlight the importance of understanding how extreme events affect the life-history of species for predicting the impacts of climate change at the individual and community level.

Changes in crop phenology across long periods of time and large scales is important in understanding the effects of climate change on crops. Here, maize observations at 112 stations across China from1981–2009, were used to investigate maize phenology changes, as well as any relations to temperature changes and cultivar shifts. The results show that maize production is adapting to climate change by shifting sowing dates and adopting cultivars that have longer growing periods. These findings can guide further maize management options under a changing climate.
