Biodiversity increases the resistance of ecosystem productivity to climate extremes
Data from experiments that manipulated grassland biodiversity across Europe and North America show that biodiversity increases an ecosystem’s resistance to, although not resilience after, climate extremes.
Ocean impact on decadal Atlantic climate variability revealed by sea-level observations
The circulation of the North Atlantic Ocean, interpreted via the sea level gradient along the US coast, is found to respond to atmospheric drivers from the North Atlantic Oscillation, and in turn influences the oceanic temperature changes…
Island Biogeography, the Effects of Taxonomic Effort and the Importance of Island Niche Diversity to Single-Island Endemic Species.
Island biogeography theory is fundamentally reliant on measuring the number of species per island and hence has taxonomy at its foundation. Yet as a metric used in tests of the theory, island species richness (S) has varied with time according to the…
Animal geographies II. Methods
Animal geographies challenge not only the place and placing of the human and the animal but, critically, the methods we use to engage with both in relation. This second review considers the various methodological implications of a more-than-human…
Human geography and archaeology
This essay explores the scope for greater engagement between human geographers and archaeologists, by taking a first step towards identifying convergences in theoretical development and possible topics for dialogue. Focusing on culturalgeography and…
Onset of Antarctic Circumpolar Current 30 million years ago as Tasmanian Gateway aligned with westerlies
Neodymium isotopes from fossil fish teeth and tectonic reconstructions show that the deep Tasmanian Gateway opened up about 33 million years ago and that the Antarctic Circumpolar Current arose 30 million years ago, when the gateway probably moved…
The contribution of outdoor air pollution sources to premature mortality on a global scale
Investigation of premature mortality by seven emission sources of atmospheric pollutants shows that outdoor air pollution, mostly by fine particulate matter, leads to more than three million premature deaths per year worldwide, which could double by…
Grassland biodiversity bounces back from long-term nitrogen addition
The negative effect of increasing atmospheric nitrogen (N) pollution on grassland biodiversity is now incontrovertible1, 2, 3. However, the recent introduction of cleaner technologies in the UK has led to reductions in the emissions of nitrogen…
Increases in tropical rainfall driven by changes in frequency of organized deep convection
An increase in the frequency of organized deep convection—essentially a large aggregation of heavily precipitating and largely stratiform clouds—is behind most of the recent increases in tropical precipitation.
Global separation of plant transpiration from groundwater and streamflow
Soil water is usually assumed to be equally available for all purposes, supplying plant transpiration as well as groundwater and streamflow; however, a study of hydrogen and oxygen isotopes from 47 globally distributed sites shows that in fact the…
The effects of life history and sexual selection on male and female plumage colouration
Classical sexual selection theory1, 2, 3, 4 provides a well-supported conceptual framework for understanding the evolution and signalling function of male ornaments. It predicts that males obtain greater fitness benefits than females through multiple…
Agriculture: Increase water harvesting in Africa
Meeting global food needs requires strategies for storing rainwater and retaining soil moisture to bridge dry spells
Do we really have a choice?
The bioeconomy and
future rural pathways
Expectations and contradictions in the rural, played out through small-scale farming, the pervasive nature of globalization, discourses of food security, new productivism and escalation in global land grabs have been shown in previous reports to…
Sustainability: Transfer project cannot meet China's water needs
Better local water management is the way to keep pace with escalating demands, not pumping water across the country, warn Jon Barnett and colleagues.
