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: Powerful IT security for the car of the future – research alliance develops new approaches

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

Im Focus: LZH showcases laser material processing of tomorrow at the LASYS 2018

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
