Most of us dont pay much attention to earthworms but maybe we should. New research suggests that non-native earthworms are radically changing the forest floor in the northern U.S., threatening the goblin fern and other rare plants in the process.
This is "the first research to show that exotic earthworms are harmful to rare native vegetation in northern forests," says Michael Gundale of Michigan Technological University in Houghton, who presents this work in the December issue of Conservation Biology.
About 10,000 years ago, glaciers pushed the range of North American earthworms southward and today the only earthworms found in most of Minnesota are non-native species introduced from Europe. Some of these earthworms eat the top part of the soil (a layer of decomposing litter called the forest floor) and this could endanger the goblin fern, a rare species that grows mostly underground.
Found only in the upper Great Lakes region, goblin ferns live between the forest floor and the underlying mineral soil. Because these tiny ferns only send up leaves briefly during the summer (and often dont emerge at all), they are thought to get some of their energy from fungi in the forest floor instead of by photosynthesizing.

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...
