Even plants benefit from outsourcing

10.11.2008
The answer to successful revegetation of native flora is in sourcing genetically diverse seed not necessarily relying on remnant local native vegetation to provide seed.

“A common belief is that local native plants are the best source of seed for revegetation projects,” says Dr Linda Broadhurst from CSIRO, Australia’s national science agency.

“It has been presumed that local seed is adapted to local conditions and therefore it would provide the best results for restoration projects.”

“However, the research shows that where vegetation loss is high and across large areas, ‘local’ seed sources are often small and isolated and can be severely inbred resulting in poor seed crops or low quality seed.”

“This can lead to germination failure and poor seedling growth.”

Land and water degradation resulting from vegetation clearance is a global problem. Effective restoration techniques are essential in reducing the damage and improving the environment.

In an effort to help, Dr Broadhurst and her colleagues have published a review on the issues associated with collecting seed for broadscale restoration projects in the new journal Evolutionary Applications (Volume 1, Issue 4).

The review covers the appropriateness of using ‘local’ seed, how much seed and the types of populations that should be sampled, and the impact that over-harvesting might have on remnant populations.

“The current emphasis on using local seed sources for revegetation will, in many cases, lead to poor restoration outcomes,” says Dr Broadhurst.

“Our findings show that seed sourcing should concentrate less on collecting from local environments and more on capturing high quality and genetically diverse seed.”

“This will ensure that restored populations have ample genetic diversity to respond to changing environments over the coming decades.”

The review, titled ‘Seed supply for broadscale restoration: maximising evolutionary potential’ is published in Evolutionary Applications in October 2008. DOI: 10.1111/j.1752-4571.2008.00045.x

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....

Im Focus: Chemical reactions in the light of ultrashort X-ray pulses from free-electron lasers

Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.

Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
