Researchers from the Mediterranean Institute for Advanced Studies (IMEDEA-CSIC) focussed on the period from 1994 to 2007 to study the persecution of the ten species of birds most often admitted to the recovery centres. The abandonment of rural life and the decrease in hunting are the reasons for the end to the war against wildlife.
Alejandro Martínez-Abraín is the main author and a researcher at the IMEDEA. "The concentration of the human population in large cities means that we no longer perceive countryside animals as enemies; the hunting of birds has also fallen as a result of the increase in awareness of the urban population through the media", he indicated to SINC.
In the study, recently published in the Zoological Society of London's Animal Conservation, 1,050 birds admitted to the La Granja de El Saler rehabilitation centre in Valencia were analyzed (55% diurnal birds of prey, 25% nocturnal birds of prey and 20% aquatic birds) in order to verify whether there has been a fall in the number of animals admitted as a result of direct persecution. The centre is dependent on the Regional Government of Valencia and is one of the largest in Spain.
This phenomenon is directly connected to the decrease in hunting. "The number of licences has fallen by 33% between 1991 and 2000 in the Autonomous Community of Valencia and the markedly downward trend is continuing", indicated Daniel Gold, who has also participated in the study.
According to Martínez-Abraín, "this is a historic moment, as the whole history of humanity has been a history of a fight against nature to survive". The separation between industrialized human beings and nature, due to urban development, means that we no longer perceive wildlife as a problem.
New threats appear
Nevertheless, in spite of the fact that the fight against animals is reaching its end in southern Europe, "we still affect wildlife in a significant manner. The fauna continues to suffer, in equal or greater measure, the indirect consequences of economic development. The collateral damage now causes more harm than the objectives of war themselves, as the metaphor goes", declared the researcher.
As for direct persecution, the illegal use of poison has increased in recent years in some autonomous communities. "But economic development is the latest and main threat to animals", declared Martínez-Abraín. Collisions and electrocutions on electricity cables, animals getting killed in wind turbines and run over on roads and the tremendous development of infrastructures fragment the territory, with serious demographic consequences in the mid and long terms.
According to Martínez-Abraín, in order to reduce the negative impact on wild animals, it is necessary "to continue increasing our ethical valuation of the conservation of biodiversity. There still remains a lot to do, and it must be done soon because we are losing our genetic heritage (the result of millions of years of evolution along an unrepeatable course) at breakneck speed", concluded the scientist.

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.
In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...
A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.
By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
