California’s native grasses can be restored

10.09.2002


A research project to restore native grasslands to a reserve in California has yielded some promising results. The native grasslands may only need to be reseeded with native seeds without having to first eradicate the invading plants from Europe, according to a presentation at the recent annual Ecological Society of America meeting by researchers from the University of California, Santa Barbara and the University of Minnesota.



The research team included Eric Seabloom, of the National Center for Ecological Analysis and Synthesis (NCEAS) at UCSB; Stan Harpole of the University of Minnesota; Jim Reichman of NCEAS at UCSB; and David Tilman, also of Minnesota.

"We used experimental seed introductions of native and exotic species to investigate one of the most dramatic plant invasions worldwide, the invasion of 23 percent of California by annual plant species introduced from Mediterranean Europe," said Seabloom. The experiments were conducted at Santa Barbara County’s Sedgwick Reserve, part of the UC Natural Reserve System which is managed by UC Santa Barbara.


Reichman, the director of NCEAS, said that the researchers found that the "native plants are actually better competitors than the invasives, but that the seed availability of natives is extremely low – probably due to grazing and drought 150 years ago."

He explained that when the researchers provided seeds of native grasses, they were competitively superior to the exotic species.

"This is encouraging news," said Reichman, "because it suggests that in many places, providing seeds will be enough to re-establish native species; there may be no need to exclude the invasives first, a profoundly difficult task."

Im Focus: New interactive machine learning tool makes car designs more aerodynamic

Scientists develop first tool to use machine learning methods to compute flow around interactively designable 3D objects. Tool will be presented at this year’s prestigious SIGGRAPH conference.

When engineers or designers want to test the aerodynamic properties of the newly designed shape of a car, airplane, or other object, they would normally model...

Im Focus: Robots as 'pump attendants': TU Graz develops robot-controlled rapid charging system for e-vehicles

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.

Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....

Im Focus: The “TRiC” to folding actin

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.

Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...

Im Focus: Lining up surprising behaviors of superconductor with one of the world's strongest magnets

Scientists have discovered that the electrical resistance of a copper-oxide compound depends on the magnetic field in a very unusual way -- a finding that could help direct the search for materials that can perfectly conduct electricity at room temperatur

What happens when really powerful magnets--capable of producing magnetic fields nearly two million times stronger than Earth's--are applied to materials that...

Im Focus: World record: Fastest 3-D tomographic images at BESSY II

The quality of materials often depends on the manufacturing process. In casting and welding, for example, the rate at which melts solidify and the resulting microstructure of the alloy is important. With metallic foams as well, it depends on exactly how the foaming process takes place. To understand these processes fully requires fast sensing capability. The fastest 3D tomographic images to date have now been achieved at the BESSY II X-ray source operated by the Helmholtz-Zentrum Berlin.

Dr. Francisco Garcia-Moreno and his team have designed a turntable that rotates ultra-stably about its axis at a constant rotational speed. This really depends...
