In this study the possibilities of the North American oak (Quercus rubra L.) as an afforestation alternative in the Basque Country Autonomous Community were investigated. The aim was to expand the range of possibilities in forestry production, avoiding monospecific plantations but, at the same time, meeting the needs of the current economy on the basis of sustainable development.
The study centred on 6 plantations of various ages in Bizkaia, firstly studying the wealth of epigeous fungi (based on sporocarps) as well as of hypogeous fungi (as ectomycorrhizals). Over a three-year period of sampling, 111 high-value species of macromycetes were studied; being grouped in 7 orders (Agaricales 60%, Russulas 18%, Boletals 14%, Polyporals 4%, Pezizales 2%, Cantharelles 1% and Phalalles 1%). The mature plantations, apart from showing a greater specific wealth, have proved to be more homogenous amongst each other than the non-mature ones. As regards ectomycorrhizals, 90 morphotypes have been described: 6 of these were identified at a species level; 1 was ascribed to a hitherto unknown morphotype and 7 to a genus. As regards the number of morphotypes, no differences were observed between mature and non-mature plantations. Winter turned out to be the season with the greatest number of morphotypes and of ectomycorrhizals types, followed by the autumn.
Also, the infective potential of the soils of the plantations was evaluated and it was observed that plantlings of 1 or 2 saps can be mycorrhized by the inoculum present in both mature and non-mature plantations.

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.
A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
