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: Computational high-throughput screening finds hard magnets containing less rare earth elements

Permanent magnets are very important for technologies of the future like electromobility and renewable energy, and rare earth elements (REE) are necessary for their manufacture. The Fraunhofer Institute for Mechanics of Materials IWM in Freiburg, Germany, has now succeeded in identifying promising approaches and materials for new permanent magnets through use of an in-house simulation process based on high-throughput screening (HTS). The team was able to improve magnetic properties this way and at the same time replaced REE with elements that are less expensive and readily available. The results were published in the online technical journal “Scientific Reports”.

The starting point for IWM researchers Wolfgang Körner, Georg Krugel, and Christian Elsässer was a neodymium-iron-nitrogen compound based on a type of...

Im Focus: Atomic precision: technologies for the next-but-one generation of microchips

In the Beyond EUV project, the Fraunhofer Institutes for Laser Technology ILT in Aachen and for Applied Optics and Precision Engineering IOF in Jena are developing key technologies for the manufacture of a new generation of microchips using EUV radiation at a wavelength of 6.7 nm. The resulting structures are barely thicker than single atoms, and they make it possible to produce extremely integrated circuits for such items as wearables or mind-controlled prosthetic limbs.

In 1965 Gordon Moore formulated the law that came to be named after him, which states that the complexity of integrated circuits doubles every one to two...
