The research has revealed that despite few animals or plants surviving the millennia of freezing cold and ice, the Irish stoats had real staying power. The Irish lineage of these small carnivores that eat mice, rabbits and birds is unique according to the research.
The scientists reached their conclusions by studying the wiry mammal’s DNA collected from museum collections and gamekeepers.
Explaining the research findings, Dr Robbie McDonald, Manager of Quercus at Queen’s, explained: “These tenacious carnivores probably survived the extreme cold at the peak of the last Ice Age by living under the snow and eating lemmings, just as they do in Greenland today.
“Irish stoats are a diverse and ancient lineage, this study provides the first compelling evidence that a species of mammal found in Ireland today actually survived throughout the worst of the Ice Age weather.
“The Irish fauna is a very unusual mix of native and introduced species, but we tend to overlook the unique nature of the Irish gene pool of many species, such as stoats and hares. This work helps identify which species should be a priority for conserving the Irish natural heritage.”
Genetic research has found that the Irish lineage of stoats is about 23,500 years old, compared to the British lineage, which is about 12,000 years old.
Stoats are found over a wide range of temperature conditions ranging from warm temperate to artic. While they currently occur in the high Artic of Greenland and Canada, feeding on lemmings, it is known from fossils that lemmings survived in Ireland providing a potential food supply during the Last Glacial Maximum (LGM).

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.
Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...
A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
