therefore contributing to better movement of genes and a successful regeneration of these trees.
But, what do voles do with the attacked acorns by beetle larvae? There is not just an answer and depends on the fact that larvae has gone out or has stayed in the acorn. Acorns whose larvae had emerged out were rapidly rejected by voles barely touching, moving or storing them. These acorns were exposed on the ground and failed to thrive in a new tree.
However, those acorns in which the larva was still inside the fruit were moved and stored by voles. The study1 reveals that voles liked these larvae (rich in proteins) and feed on them, decreasing the harm produced by these worms over the acorns. Therefore, voles scattered and buried these acorns that finally contributed to generate new plants. The fact that the larva was still inside resulted definitive for the near future of the acorn, and therefore, the future of oak forests.
The nature maintains its compensation mechanisms and, an apparent harmful beetle can be attractive to voles that, at the same time, releases acorns from this enemy and help them to thrive thanks to its rich substance what allows them to survive winter and maintain this favorable relationship between vole and acorn.
These results reveal that we do not know ye the behavior of those ecosystems that we aim to preserve. The knowledge of multiple existing interactions among animals and plants are essential to know what should be protected and how our forests should be protected.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
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.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
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...
