New species of sedge found in UK triggers search for new populations

08.02.2007
New species suggests stormy times ahead
Species of sedge new to the UK is discovered in Scotland

Botanists at Edge Hill University, the UK’s newest University, have discovered a population Carex salina (Salt-marsh sedge), near Morvich on the west coast of Scotland, in the UK for the first time. Scientists from the University are calling on members of the public to help them search for other populations of this species. Identification keys and recording forms are available from the University’s website.

‘We are really keen to enlist the help of others in looking for this species of sedge that, as far as well can tell, is new to the UK,’ said Dr Paul Ashton, Senior Lecturer in Biology at Edge Hill University. ‘It is entirely possible that this plant has been on our shores for many years and just overlooked, but we will never know that unless people help us with our study. If we discover that Salt-marsh sedge is entirely new to the UK it will be a very exciting find that will enrich our knowledge of British flora.’

The new species of sedge was discovered by Keith Hutcheon on 2 July 2004, while undertaking a National Vegetation Classification survey of the Kintail Estate for the National Trust of Scotland. Sedge are typically grass-like plants but are most easily separated from grasses and rushes by their triangular stems. It was originally thought that the sedge was the species Carex recta, (Estuarine sedge) the only other UK species of sedge likely to be found in the area that can withstand such high levels of salt water.

Dr Paul Ashton and Dr Mary Dean, from Edge Hill University, began the process of identifying the specimens that were collected. After consultation with colleagues from Canada and Norway they came to the conclusion that the species must be Carex salina, which is found in both those countries but never before seen in the UK.

Salt-marsh sedge is thought to be a result of hybridisation between two other plants Carex paleacea (Beach sedge) and Carex subspathacea (Cold Sea sedge), however neither of these parent species are present in the UK botanical record. It is thought that the Scottish location is the first area in the world where Salt-marsh sedge is apparently growing outside of the ranges of parental species. Botanists at Edge Hill are trying to research the reason for its appearance on UK shores; it could have originated in Scotland by long distance dispersal, alternatively it may have arisen in situ and the parent species are now extinct, or are still present in the UK but are currently undetected.

If migration of this species from the colder, stormier climates like those on the coast of Norway and North America has taken place the presence of Carex salina could be an indication of stormier times ahead for the UK coast. Botanists need to first establish whether there are other populations of this hybrid species, or of its parents, in the UK before investigation into migration and possible climate repercussions can take place. However, two scientists cannot carry out this survey on their own, which is why the website has been set up to enlist the help of the botanical enthusiasts in sampling possible populations.

This survey will take place over 3 years and results will inform future studies into sedge species, and their related habitats on the UK coastline.

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: 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...
