Despite of that, no study ever proposed key broad-scale regions for conserving these species till now. Rafael D. Loyola and his colleagues propose now a priority set of areas for the conservation of frogs and toads in Latin America.
The study, published in this week’s PLoS ONE, is unprecedented in terms of not only the proposition of key-conservation areas, but also because it shows that the inclusion of species biological traits, such as reproductive modes, affects the performance of area-prioritization analyses.
Loyola and coauthors separated 700 frog and toad species into two major groups: those that exhibit an aquatic larval stage (tadpoles) during its life-cycle and those that do not. They find regions of particular importance for each of these groups and combined the results to attain a set of priority areas for the conservation of species. These regions are concentrated in the Andes and Central America, with some important areas also appearing in Mexico and Brazil.
The researchers suggest that if frog and toad developmental modes are not considered most regions essential for preserving species with tadpoles will be lost, leading to inefficient conservation strategies for these animals and to the lost of the Latin America’s unique natural heritage.

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.
In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...

For the first time, scientists have succeeded in studying the strength of hydrogen bonds in a single molecule using an atomic force microscope. Researchers from the University of Basel’s Swiss Nanoscience Institute network have reported the results in the journal Science Advances.
Hydrogen is the most common element in the universe and is an integral part of almost all organic compounds. Molecules and sections of macromolecules are...
