“With the results we present in this article, we’ve rewritten the entire history of Amazonia in terms of the development of its biodiversity,” says Alexandre Antonelli from the University of Gothenburg’s Department of Plant and Environmental Sciences, and scientific curator at the Gothenburg Botanical Garden (Sweden).
Amazonia’s wealth of species is by far the greatest in the world. Although researchers have long suspected that the diversity of the Amazonian rainforest was affected by the Andes, the causal links have been unclear until now, and there have been a wide range of scientific theories on the origins of the species found there.COMPARED DATA FOR 65 MILLION YEARS
“We suspected from some scattered fossils and dated species trees that the Amazonian diversity arose after the separation from Africa. So we looked at the whole period. I worked mainly on coordinating a survey of DNA-based studies of the relationships between different species of plants and animals. We’ve examined hundreds of scientific publications and have found that very few of the genera are as young as people thought.”GREATEST BIODIVERSITY IN CONNECTION WITH THE ANDES
“We were surprised that there was such a strong link between the formation of the Andes and the diversity in Amazonia,” says Antonelli, who was born in Brazil. “The area was considered a kind of paradise where evolution could take place undisturbed, but this hasn’t been the case at all – a lot has happened in the region.”
The article Amazonia through time: Andean uplift, climate change, landscape evolution, and biodiversity was published in the journal Science on 12 November. The 18-strong team behind the article includes researchers from the Netherlands, Switzerland, Spain, the UK, Sweden, Brazil, Colombia, Panama, Venezuela and the US.Subscribers can download the article from: www.sciencemag.org/cgi/content/short/330/6006/927, or a copy can be requested from Alexandre Antonelli (see below for contact information).
The results were presented at a seminar in Amsterdam, the Netherlands, on the same day: www.science.uva.nl/ibed/home.cfmFor further information, please contact: Alexandre Antonelli, Department of Plant and Environmental Sciences, University of Gothenburg, and Gothenburg Botanical Garden

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
