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.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
