The vegetable species of Sierra Nevada are the 30% of Spain’s floral richness and they are impoverishing due to the maintenance with heavy plant of the ski runs. Soil erosion is increasing and the loss of biodiversity gets worse, as 80 of the more than 2,000 vascular plants present are endemic of this massif.
This new experiment, whose results will be published in the next issue of the Central European Journal of Biology, will permit “to recover the spoiled areas, improve the present restoration methodology of the vegetable cover and landscape integration, and favour the preservation of biodiversity in such a fragile area such as Sierra Nevada”, explains to SINC Francisco Serrano Bernardo, main author of the study and Researcher in the field of Environmental Technologies.
The scientists studied two native bushy species of Sierra Nevada, among other taxons: Genista versicolor Boiss (Leguminous) and Reseda complicata Bory (Resedacea), whose ecological niche is, above all, in the ski resort and its environment.
In order to manage the recovery in its natural environment, the researchers wanted to know “some environmental requirements such plants need to optimize their germination and growth processes”. The main problem of bushes is that, in the short term, “they do not manage to regulate themselves to recover their biodiversity naturally”.Seeds growing in the laboratory
Treatments with different vegetable growth regulators (auxins, gibberellins, cytokinins and ethylene) were applied to the seeds “to improve germinative and growth percentages in laboratory and make easier the later transfer and application of the results to the ski resort”, the researcher says.
Seeds germinated and grew successfully in the laboratory. According to Serrano, the effectiveness of the regulators has been tested in aspects such as the formation of the radical system, stem elongation, cotyledon expansion (simple leaves which feed the plant) or leaves appearance.
Once the treatments are applied to the field, they are expected to “favour the recovery of the vegetable cover in a space of time considerably lower to that needed without any intervention”, the experts say.

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
