Parasites fail to halt European bumblebee invasion of the UK

04.06.2014

A species of bee from Europe that has stronger resistance to parasite infections than native bumblebees has spread across the UK, according to new research at Royal Holloway, University of London.

The study, published today (Wednesday 4th June 2014) in the Journal of Animal Ecology, shows that tree bumblebees have rapidly spread despite them carrying high levels of an infection that normally prevents queen bees from producing colonies.

The species arrived in the UK from continental Europe 13 years ago and has successfully spread at an average rate of nearly 4,500 square miles – about half the size of Wales – every year.

Researchers collected tree bumblebee queens from the wild, checked them for parasites and then monitored colony development in a laboratory.

Despite the bees having low genetic diversity and high levels of a nematode parasite that usually castrates other species, 25 per cent of the queens were able to produce offspring.

Scientists believe the spread of tree bumblebees could have both positive and negative impacts on native bees.

"Since its arrival to the UK, the tree bumblebee has been rapidly spreading despite high levels of this castrating parasite", said researcher Catherine Jones, from the School of Biological Sciences at Royal Holloway.

"Bees are essential to our food chain and the populations of our native bumblebees have declined in recent decades. The arrival of tree bumblebees could be hugely beneficial to us by absorbing parasite pressure from our native species, as well as helping to pollinate wild plants and crops."

Professor Mark Brown, from the School of Biological Sciences at Royal Holloway, added: "While these findings show promising signs for bee populations in the UK, we still don't know whether there could be any negative impacts if the bumblebees compete for food or nesting sites. Further research should focus on how our native bees are affected and the pollination services that this new species provides."

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...
