Wildlife need more complex travel plans

21.10.2008
A new UC Davis study says that people trying to help nature by designing corridors for wildlife need to think more naturally.

"Human beings tend to think in terms of regular, symmetrical structures, but nature can be much more irregular," said UC Davis postdoctoral researcher Matthew Holland, the study's lead author. "We found that symmetrical systems of corridors may actually do less good for natural communities than designs with some randomness or asymmetry built in."

Corridors are physical connections between disconnected fragments of plant and animal habitat. A corridor can be as big as a swath of river and forest miles wide that links two national parks, or as small as a tunnel under an interstate highway.

Without such connections, animals cannot travel to food, water, mates and shelter. Plants cannot disperse their pollen and seeds to maintain healthy, genetically diverse populations.

Designing and implementing corridors (sometimes called corridor ecology or connectivity conservation) is a new subfield in environmental science. Holland's research is among the first to help land managers and community planners designing corridors to know what will work and what will not.

Holland's co-author is UC Davis theoretical ecologist Alan Hastings. Hastings is one of the world's mostly highly regarded experts in using mathematical models (sets of equations) to understand natural systems. His analyses have shed light on environmental issues as diverse as salt marsh grass invasions in San Francisco Bay; climate change and coral reefs; and marine reserves and fish populations. In 2006, Hastings received the Robert H. MacArthur Award, the highest honor given by the Ecological Society of America.

Im Focus: Manipulating Electron Spins Without Loss of Information

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.

For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...

Im Focus: The proton precisely weighted

What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.

To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
