100,000 More Plants Than Previously Thought - endangered?

25.06.2002


A new study reveals a far greater diversity of plants on earth than previously estimated. Writing in the latest Plant Talk magazine (published on 12 June), leading botanist and conservationist Dr David Bramwell calculates that there are around 422,000 species of flowering plants (termed Angiosperms) in the world. Until now, most scientists had worked from a much lower figure of some 270,000 or 320,000 species.



The increased estimate shows that there is an even more urgent need to complete the global inventory of plant diversity. Much of this botanical wealth is in parts of the world where species-rich tropical and Mediterranean habitats are disappearing the fastest.

Dr Bramwell said, "The plant kingdom is even richer than we thought. It is even more urgent to find the people to identify the species and classify them before it is too late."


The increased tally does not make the loss of endangered species any less serious. Indeed, this new calculation indicates that many more species than previously thought are threatened with extinction. Using his new figures, Bramwell estimates that at least 94,000 plant species are under threat.

The new estimate greatly boosts the argument that more resources should be allocated to the classification and conservation of plant diversity. The world faces a declining community of taxonomists (the scientists who identify and classify plants), of people able to identify plants in nature and of those who can teach others how to do so. At the same time, the crisis of biodiversity loss is growing, not diminishing.

Commented Plant Talk editor Hugh Synge, "Botanical inventory is slowing down just at the time when it needs to be speeded up, when the loss of vegetation makes it ever more urgent."

Im Focus: In best circles: First integrated circuit from self-assembled polymer

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

Im Focus: Hybrid optics bring color imaging using ultrathin metalenses into focus

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.

But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...

Im Focus: Stem cell divisions in the adult brain seen for the first time

Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.

The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...

Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters

Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
