Will earlier springs throw nature out of step?

09.02.2010
The recent trend towards earlier UK springs and summers has been accelerating, according to a study published today (9 February 2010) in the scientific journal Global Change Biology.

The collaborative study, involving scientists from 12 UK research institutions, universities and conservation organisations, is the most comprehensive and rigorous assessment so far of long-term changes in the seasonal timing (phenology) of biological events across marine, freshwater and terrestrial environments in the UK.

Led by Dr Stephen Thackeray and Professor Sarah Wanless of the Centre for Ecology & Hydrology, the research gathers together more than 25,000 long-term phenology trends for 726 species of plants and animals. More than 80% of trends between 1976 and 2005 indicate earlier seasonal events. The study considers a diverse array of organisms including plankton, plants, insects, amphibians, fish, birds and mammals. On average, the seasonal timing of reproduction and population growth has become earlier by more than 11 days over the whole period, but change has accelerated in recent decades.

The research shows that there are large differences between species in the rate at which seasonal events have shifted. Changes have been most rapid for many organisms at the bottom of food chains, such as plants and the animals that feed upon them. Predators have shown slower overall changes in the seasonal timing of their life cycle events. However, the seasonal timing of reproduction is often matched to the time of year when food supply increases, so that offspring receive enough food to survive. A key question is whether animals higher up the food chain will react to the faster rates of change in the plants and animals they feed upon, or whether they will fail to do so and become less successful at rearing their offspring.

Dr Thackeray said, "This is the first time that data have been analysed with enough consistency to allow a meaningful comparison of patterns of changing seasonal timing in the UK among such a diverse range of plants and animals."

Professor Wanless said, "It is important to realise that this analysis doesn't identify which predator-prey relationships are most at risk of disruption due to changes in timing. What it does do is highlight that the recorded changes need urgent investigation, particularly for species with high economic or conservation importance."

Co-author Richard Smithers of the Woodland Trust said, "Phenology is 'the canary in the cage'. The results of this new study make real our changing climate and its potential to have profound consequences for the complex web of life."

The research was funded by the Natural Environment Research Council and carried out by staff from the Centre for Ecology & Hydrology, Woodland Trust, Butterfly Conservation, University of Cambridge, Rothamsted Research, Marine Scotland, Royal Holloway University of London, Sir Alister Hardy Foundation for Ocean Sciences, Freshwater Biological Association, People's Trust for Endangered Species, British Trust for Ornithology, and the National Pollen and Aerobiology Research Unit University of Worcester. Two of the research team, originally based at the Centre for Ecology & Hydrology, have since moved to Poznan University of Life Sciences in Poland and the Natural Environmental Research Institute in Denmark.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
