Measuring ‘impact’ - news of highly downloaded papers

There are many ways these days to measure the impact of scientific publications but it’s always nice to be told that people are actually downloading your paper (of course, whether they read it or not is a different matter!).

Various scientific journals have collated all kinds of statistics covering activity in 2014 - some have now published lists of their most downloaded articles.

Members of CEH’s Plant-Soil Interactions group (based at our Lancaster site) figure prominently in the top download list from Global Change Biology Bioenergy. The group, which has conducted research on bioenergy for a number of years, including on projects such as ELUM and Carbo-Biocrop, are lead or co-authors on 4 of the 15 most downloaded GCB Bioenergy articles in 2014.

Well done to all involved!

The CEH staff and students are highlighted in bold:
Can biochar reduce soil greenhouse gas emissions from a Miscanthus bioenergy crop?

Modelling the carbon cycle of Miscanthus plantations: existing models and the potential for their improvement
Andy D Robertson, Christian A Davies, Pete Smith, Marta Dondini and Niall P McNamara
Meanwhile another CEH-led paper, "Horizon-scanning for invasive alien species with the potential to threaten biodiversity in Great Britain", was one of the top 15 most downloaded articles from the Global Change Biology journal last year. Lead author Dr Helen Roy told us the news was very exciting, and said she was delighted that the research had been of such interest.

This prescient paper was published before sightings of the Quagga mussel and Asian shore crab were confirmed in Britain later in 2014. There were also some unconfirmed sightings of raccoons. Interestingly, being published in May 2014, it is one of the more recent publications on the list! A 2002 article on climate change effects on insect herbivores, co-authored by former and current CEH staff members, was also among the top 15 downloaded from GCB. Again, well done to all the authors!

Ladybirds, fungi and alien invaders

Dr Helen Roy reveals why she is fascinated by Hesperomyces virescens and Harmonia axyridis.

Of all species on Earth it is the parasites that seem to receive least appreciation for their intrinsic beauty. Yet they are exquisite. I have been fascinated by parasites for many years, particularly fungal pathogens of insects. I began my exploration of these intriguing fungi through studies on an obligate parasite of aphids – Pandora neoaphidis. The intricate fungal structures of this delicate (and lethal) fungus when viewed under the microscope are simply beautiful but perhaps even more inspiring are the amazing ways in which this fungus interacts so intimately with the host aphids it infects. It can alter the behaviour of aphids in dramatic ways even affecting the communication between aphids to enhance transmission.

Ladybirds also play a part in the dispersal of this aphid-pathogenic fungus but they are also host to their own fungal parasites too.

Recently Katie Murray, a PhD student based at the University of Stirling but who I have the pleasure of also supervising, found one of the most quirky groups of fungi infecting Harmonia axyridis (harlequin ladybird) in London - the Laboulbeniales. The species of fungus is called Hesperomyces virescens and has previously been studied within Adalia bipunctata (2-spot ladybird) in London.

I met Katie, and her co-supervisor Matt Tinsley, the day after she had made her discovery. The fungus utterly captivated us all. The small yellow fruiting bodies that protrude from infected individuals are striking. The supervisory meeting was dominated by our lively and excitable speculations on the life-history of this fungi and specifically the extent of the epidemic that Katie had stumbled upon. We have so many questions and so few answers.

We are now hoping that people across the UK can help us unravel the mysteries of this unique parasite by contributing to a new parasite survey. As harlequin ladybirds move into people’s homes this winter we are encouraging them to submit photographs, count how many ladybirds they spot and how many appear to have the fungal infection. You can find out more details about Laboulbeniales fungi and take part in the parasite survey here.

Dr Helen Roy is an Ecological Entomologist, working within the Biological Records Centre at the Centre for Ecology & Hydrology. She also leads the UK Ladybird Survey.

More information about the appeal for citizen scientists to help in mapping the fungal epidemic can be found on the CEH News Centre.

Invasive alien quagga mussel arrives in UK

The invasive alien quagga mussel (Dreissena rostriformis bugensis) has arrived in the UK. The mussel was found in Wraysbury Reservoir and the Wraysbury River, a tributary of the River Colne, near Egham, Surrey.

Top threat


Earlier this year a CEH-led invasive alien species horizon scanning exercise identified the quagga mussel as the top ranking threat to the UK’s biodiversity. The study, published in Global Change Biologyconcluded that the mussel poses a high risk because it is an ecosystem engineer with the potential to disrupt the ecological function of freshwater environments.

The horizon scanning exercise was carried out by scientists from more than 20 research institutes and universities with expertise on invasive alien species. It aimed to collate a list of invasive alien species not yet established within Britain but anticipated to arrive, establish and threaten biodiversity within five years.

Other high risk species


In addition to the quagga mussel the exercise identified a further 29 high risk species, including the Sacred ibis, the Brush clawed shore crab, the Asian hornet, and the American water-milfoil. Since the paper was published, the first UK record of the non-native Asian shore crab (Hemigrapsus sanguineus), which was included in the top 10 potential threats, has been received.

How to record sightings


An alert system operates within the UK for invasive species. The latest species alerts can be found here. If you see the quagga mussel or any other invasive alien species of concern, please report your sighting via iRecord: http://www.brc.ac.uk/irecord/enter-non-native-records

More information


The horizon scanning exercise was published in the scientific journal Global Change Biology. The paper is open access.

Dealing with invasive non-native species - new EAC report

Updated 16 April

The Environmental Audit Committee (a UK Commons Select Committee) report on invasive non-native species was published this morning and has been widely reported within the UK media including BBC Online, the Guardian and the Daily Mail.

In response to publication Dr Helen Roy of the Centre for Ecology & Hydrology said, "It is critical that we increase our understanding of the threat to biodiversity posed by invasive non-native species. People can play a major part through surveillance by reporting sightings of concern to the GB Non-Native Species Information Portal."

Current species alerts include Asian hornet, Killer shrimps and Quagga mussel. More information on the GB Non-Native Species Information Portal hosted by the Non-Native Species Secretariat.

Professor James Bullock of CEH leads an EU wide project on on invasive ragweed. Common ragweed is an alien species which is highly invasive across Europe and has harmful impacts on a range of sectors, especially human health and agriculture. A recent report on the project can be downloaded here (large >20mb pdf).

Original post

Tomorrow morning, Wednesday 16 April, the Environmental Audit Committee (a UK Commons Select Committee) will publish a report on invasive non-native species. The report concludes an inquiry by the Committee that examines the government's policy on invasive species and the implications of the European Commission's draft EU Directive on "the prevention and management of the introduction and spread of invasive alien species".

Dr Helen Roy from the Centre for Ecology & Hydrology (CEH) gave oral evidence to the committee on 22 January 2014. Dr Roy's research covers the dynamics of invasive non-native species and their effects on native biodiversity. She chairs the COST Action ALIEN Challenge project which involves 27 countries in work to ensure a fair exchange of high quality and reliable data and information on invasive non-native species. She also leads a project to produce a comprehensive information portal on non-native species in Great Britain and manages updates to the DAISIE (Delivering Alien Invasive Species Inventories for Europe) database. Dr Roy has previously blogged on invasive species research for us (Invasive Alien Species: From Data to Decisions) and Planet Earth Online (Aliens descend on Britain).

The Report will be available on the Committee’s website from 00.01 am approximately, on Wednesday 16 April 2014.

Natural Hazards Science Area

CEH's new Science Strategy identifies three interdependent, major societal and environmental challenges: Securing the Value of Nature, Building Resilience to Environmental Hazards, and Managing Environmental Change. We're delivering our strategy by Science Areas and underpinning activities, and over the next few weeks we are profiling these on our blog.

In this post we focus on our Natural Hazards Science Area, which includes some of our work on floods and droughts. Natural hazards also include threats from parasites, pathogens and invasive species, and threats from natural air pollution incidents.




Natural hazards are of increasing concern for humanity because of population growth and increased societal vulnerability due to trends in urbanisation and land-use change. They have been identified by the National Security Review as some of the most significant risks to the UK in terms of economic, social and environmental consequences.

A key demand is to improve our prediction and estimation of natural hazards and develop knowledge to better manage and minimise their impacts on our society, economy and environment.


Hydro-meteorological science is an important element of our research. Within CEH we have teams of scientists working on furthering our understanding of hydrological processes, water resources, water information management, hydrological status and reporting, the climate system, hydrological modelling and risk, and hydrological modelling and forecasting. Our science and data played a key role in informing UK operational agencies during the recent flooding events.


Our future research objectives include the development of physical and statistical models to better quantify the current and future risks from extreme rainfall and floods at multiple temporal and spatial scales. We are also developing web-based tools for seasonal forecasting of river flows to support flood and drought management in the UK and overseas.

What is a drought? - read more on the CEH website

CEH also has an important research role in helping to develop solutions to tackle problems caused by biological invasions.


We are working on methods to supply predictions of their arrival and spread, underpinned by rigorous risk assessment. We will deliver new systems to predict the arrival of invasive non-native species with particular focus on their pathways of arrival, spread and associated disease pathogens.

A look at ladybirds, drugs and floods - CEH paperblog 9

For our first paperblog of 2014 we take a look at ladybirds, drugs and floods.

We start with three new papers highlighting different aspects of ladybird research (although the invasive Harlequin ladybird (Harmonia axyridis) figures prominently in each!).

In a paper in Biological Invasions, Richard Comont and colleagues from CEH and Rothamsted Research explore the relative importance of life-history and resource-use traits, as well as climate, habitat and the impact of the Harlequin ladybird, in driving local extinction and colonisation dynamics across 25 ladybird species. They found that the only factor that both increased the local extinction likelihood and reduced colonisation likelihood was urban land cover, while ecological overlap with the Harlequin ladybird greatly increased extinction rates.

Richard was also lead author of the paper "Escape from parasitism by the invasive alien ladybird, Harmonia axyridis", published in Insect Conservation and Diversity. The astonishing success of the Harlequin ladybird in Britain has given researchers a unique opportunity to investigate a key ecological theory, the Enemy Release Hypothesis. You can find out more in our news story, Harlequin ladybirds escape enemies while native species succumb.

Both studies above featured Dr Helen Roy (@UKLadybirds) as a co-author. Helen also features on the final ladybirds paper we highlight, in PLOS ONE, in which scientists used radar data to reveal the astonishing heights (up to ~1100 metres) and speeds (up to ~60 km per hour) of ladybird flight paths. Average flight time was estimated to be 36.5 minutes, although flights of up to two hours were observed. The results have important implications for predicting long-distance dispersal of these important aphid predators (the paper is open access).

We move from ladybirds to the aquatic environment, in particular the presence of pharmaceuticals in the wider aquatic environment, an area of growing concern and research. "The apparently very variable potency of the anti-depressant fluoextine" (you may have heard of one of its trade names, Prozac) is examined in an open access paper in Aquatic Toxicology. Professor Andrew Johnson of CEH is a co-author. The researchers admit that not very much can be concluded at the moment, as the apparent variability in sensitivity of different aquatic species prevents a consensus being reached. It will take years and a lot more reproducible research to answer the question of whether it presents an environmental risk.

Anticancer drugs are the focus of another paper, again featuring Prof Johnson as well as CEH colleagues Neville Llewellyn and Richard Williams. In "Prioritising anticancer drugs for environmental monitoring and risk assessment purposes", published in Science of the Total Environment, scientists establish a shortlist of drugs that can 'breakthrough' to receiving waters, being sufficiently persistent to warrant inclusion in environmental screening programmes.

We finish with a new floods research paper published in Natural Hazards and Earth System Sciences which attempts to reassess flood frequency for the Sussex Ouse by including historical information. Systematic flood level readings from 1960 and accounts detailing past flood events within the catchment are compiled back to c.1750. This extended flood record provides an opportunity to reassess estimates of flood frequency over a timescale not normally possible within flood frequency analysis. The researchers say their findings support calls for greater use of historical flood information in flood frequency analysis, as a means by which uncertainty can be reduced in high magnitude flood estimation. The paper is still in the discussion stage and is open for comments until 13 February.

The Harlequin ladybird, Harmonia axyridis: time for global collaboration

International cooperation is very important in preventing and controlling the spread of invasive species globally, as Helen Roy and Peter Brown of the UK Ladybird Survey explain in a guest blog:

It is almost ten years since the Harlequin ladybird, Harmonia axyridis, was first recorded in the UK. This invasive alien species is native to Asia and so it is particularly poignant for us to have been invited to speak at the International Congress on Biological Invasions hosted at Qingdao*, China.

We're taking part in a session entitled "Harmonia axyridis: time for global collaboration" and feel privileged to be here representing the UK Ladybird Survey, alongside the Centre for Ecology & Hydrology and Anglia Ruskin University. During our time in China we are presenting research spanning predator-prey and natural enemy interactions through to host plant and habitat associations. All possible because of the records collated by the UK Ladybird Survey.

The online UK Ladybird Survey (including the Harlequin Ladybird Survey) was launched in 2005 following the arrival of the harlequin ladybird in the UK. We could not have imagined the response - tens of thousands of people from across the UK have contributed records of the harlequin ladybird and native species of ladybird. These observations have been invaluable in providing a unique insight into the ecology of this invader and the effects it is having on native species.

The threat posed by invasive alien species is widely recognised and the harlequin ladybird provides a model system for exploring invasion biology making the data collected through the UK Ladybird Survey extremely valuable . The success of the online survey has also provided the inspiration for the development of a system for reporting many other alien species in Britain. 

One aim of our visit to China is to strengthen collaborations with researchers from around the world, and in particular to forge links with scientists working here. We hope to build on our understanding of how the ecology of the harlequin ladybird differs in its native and invaded ranges.

The harlequin ladybird is a dominant species in China as it is within the invaded range. Today we had the opportunity to observe, with excitement, the harlequin ladybird on the seafront trees of Qingdao. It was a fitting conclusion to a very productive and worthwhile trip.

Biodiversity indicators and the Biological Records Centre

The 2013 update to the UK Biodiversity Indicators has just been published on the JNCC website.
 
CEH scientists working within the Biological Records Centre contribute to several of the indicators, building on our wealth of knowledge and links to most of the UK's wildlife recording schemes. In particular, for 2013, our scientists have contributed to development of the new index on the status of priority species (C4a).

Dr Nick Isaac of CEH explains more:

"The new indicator C4a uses data from national surveys, such as the UK Butterfly Monitoring Scheme. The index provides an annual summary of the abundance of 210 mammal, bird, butterfly and moth species, all of which have been identified as priorities for the four national conservation agencies. This property makes this index much more sensitive than the old C4, in which species were categorised as declining, stable or increasing based on expert opinion."

"In addition, we also produced a supplementary index based on distribution data. These 'biological records' are not collected in a standardised way, which makes the data extremely noisy and liable to produce biased estimates of species trends. Within the Biological Records Centre, we've invested heavily in trying to understand this bias, and to extract a meaningful signal of change from the noise in the data. This investment has now paid off, because we're now able to report on the status of  taxonomic groups, such as bees, that lack standardised monitoring schemes."

"Both the abundance and distribution-based indicators show a decline of 50-60% since 1970, reinforcing the message that conservation agencies have their work cut out to prevent more species from going extinct."

More details of the C4a indicator can be found in the technical report, "Status of threatened species - status of priority species".

Other UK biodiversity indicators with CEH involvement include:

  • C6. Insects of the wider countryside (butterflies) population (data from CEH's joint stewardship of the UK Butterfly Monitoring Scheme with Butterfly Conservation)
  • C2. Habitat Connectivity (Countryside Survey data)
  • B6. Pressure from Invasive species (reflecting our work with the National Biodiversity Network)
  • B5. Pressure from Pollution
  • C7. Plants of the wider countryside (data from CEH's Countryside Survey)

CEH science also played a key role in the 2011 National Ecosystem Assessment, which is the basis of Indicator D2. Biodiversity and ecosystem services (terrestrial).

Ragweed models and Bird Island measurements - CEH paperblog 6

In our latest paperblog, we first highlight two new papers resulting from a European Commission-funded project to assess and control the spread and effects of Common ragweed in Europe. Accurate models are needed to forecast the progress and impact of alien invasive species. For Common ragweed Ambrosia artemisiifolia such forecasts are extremely important as the species is a serious crop weed and its airborne pollen is a major cause of allergy and asthma in humans.

Newly published in Global Change Biology, Dan Chapman leads the paper, "Phenology predicts the native and invasive range limits of common ragweed", collaborating with CEH colleague Prof James Bullock and researchers from the UK, Austria and South Africa. Their study shows that phenology can be a key determinant of species' range margins, and thus integrating phenology into species distribution models can offer great potential for the mechanistic modelling of range dynamics.

Dan and James are co-authors of a second paper entitled "An operational model for forecasting ragweed pollen release and dispersion in Europe", published in Agricultural and Forest Meteorology and led by the Finnish Meteorological Institute. This study produces the first European-scale simulation of ragweed pollen concentrations. The modelling illustrates the potential for a relatively localized invasive species to produce impacts on human health at a continental scale.

The remote Bird Island in the south Atlantic is home to large seabird and seal colonies, including Macaroni and Gentoo penguins, and Antarctic fur seals. Our NERC colleagues British Antarctic Survey have a research station there. A new open access paper in Atmospheric Chemistry and Physics involving the Max Planck Institute for Chemistry, CEH, BAS and Kings College looks at how Bird Island's fauna are influencing the composition and characteristics of remote marine aerosol measured on the island. Many aspects of marine aerosol systems are not yet fully understood, but a detailed understanding is essential to quantify more fully the role of marine aerosol in the functioning of the Earth system.

The study, which saw the first stationary deployment of an aerosol mass spectrometer to a field site in the sub-Antarctic, generally found the aerosol to be less acidic than in other marine environments due to the high availability of ammonia from local fauna emissions.

Finally, we highlight a paper by Professor Colin Neal who recently retired from the Centre for Ecology & Hydrology but who remains a research fellow of the organisation. Colin's invited commentary in Hydrological Processes discusses "Catchment water quality: the inconvenient but necessary truth of fractal functioning", drawing on his long-term research, particularly at the Plynlimon catchments in Wales (data freely available from the CEH Information Gateway).

Making ecology count at the INTECOL Congress, London

The 11th INTECOL Congress, the world's largest international ecology meeting, comes to London next week (18-23 August 2013) as part of the centenary celebrations of the British Ecological Society, and Centre for Ecology & Hydrology scientists and PhD students will be there!

The theme of this year's Congress is "advancing ecology and making it count". It's a very significant event: the ecological science to be presented covers everything from aquatic ecology to island biogeography to species interactions, through a series of 43 symposia, 31 workshops, 56 oral sessions, 11 plenary talks, 500 posters, as well as social events and scientific trips. More than 2000 ecologists from 67 countries will be attending. Details of all the sessions can be found on the INTECOL website or with the very useful app produced for the conference.

We highlight just some of the CEH participants below to give a little taste of our own ongoing research in the field of ecology.

Stephen Thackeray, a lake ecologist based at our Lancaster site, is among those scientists who will deliver a keynote talk in one of the symposia. Stephen, who is currently coordinating the NERC-funded phenology project "Shifting seasons, climate change & ecosystem consequences", will present on Friday on trophic asynchrony: definitions, drivers and consequences in aquatic and terrestrial systems. The phenology symposium looks at perspectives from ecosystems across the International Long Term Ecological Network.

Busy both organising and presenting during the week is ecologist Matt Heard. Along with Adam Vanbergen of CEH, who is science coordinator of the Insect Pollinators Initiative, and Simon Potts, University of Reading, Matt has organised a symposium for Thursday entitled "Threats to an ecosystem service: evaluating multifactorial pressures on insect pollinators". The keynote at the symposium will be delivered by Claire Kremen of the University of California.

Pressures on pollinators are a global concern



During the symposium, Matt will present results from a project led by Claire Carvell of CEH that is aimed at helping to understand the effects of land management and habitat structure on bumblebee behaviour and colony dynamics. Additionally, Matt is involved in a separate session on Wednesday on the theme of agricultural ecology, when he will talk about how agri-environment scheme management enhances wildlife diversity and abundance at different scales.

Michael Pocock, co-author of the recent Guide to Citizen Science, is organising a workshop on citizen science to take place on Thursday afternoon. This will give participants the opportunity to hear about some of the leading technologies in citizen science and to try out some for themselves, maybe even be inspired to collaborate on some new ideas. Michael, who co-leads the Conker Tree Science project and who researches the complexity of ecological networks, will also be presenting a talk in a separate session that will look at the diversity of environmental and ecological citizen science.

Helen Roy, coordinator of the UK Ladybird Survey and another co-author of the Guide to Citizen Science, will also be involved in the workshop. Helen also has a separate talk on scanning for aliens in a session on invasive species which she will also chair.

Other CEH scientists presenting throughout the week include Owen Mountford on assessing the quality of agri-environment agreements, Ed Rowe on predicting effects of nitrogen pollution on soils, Danny Hooftman on mapping ecosystem services and biodiversity, Tom Oliver on impacts of climatic extremes, Gary Powney on species distribution change, Rosie Hails on population dynamics and Nick Isaac on trends in the status of UK biodiversity.

county over 70 years were mapped for a CEH study.


Importantly, an event like INTECOL also gives the opportunity for a number of our PhD students to present details of their projects in both talks and poster sessions. Those giving talks include Philip Martin, CEH and Bournemouth University, who will present "Carbon pools recover more quickly than plant biodiversity in tropical secondary forests", and Andrew Cole, CEH and Lancaster University, who will present on climate change and plant diversity effects on grassland function.

Good luck to everyone taking part, especially those who are travelling long distances to share details of their work. If you're not at INTECOL itself, keep your eyes peeled for press coverage of some interesting new science. Meanwhile, the hashtag to follow on Twitter is #INT13.

Reflections on the science underpinning the EU Biodiversity Strategy

Science underpinning the EU 2020 Biodiversity Strategy
CEH is involved in a number of cross-European partnerships and initiatives – international collaboration is a major feature of our science. One such initiative is ALTER-Net (a Long-Term Biodiversity, Ecosystem and Awareness Research Network), which comprises 26 partner institutes from 18 European countries. ALTER-Net integrates research capacities across Europe: assessing changes in biodiversity, analysing the effect of those changes on ecosystem services and informing policy makers and the public about this at a European scale.
Together with the European Commission, ALTER-Net has organized a major conference which has been taking place in Ghent, Belgium this week, during which participants are discussing the implementation of the 2020 European Biodiversity Strategy. Specifically, conference members are looking for scientifically sound, evidence-based recommendations on how to implement and realize the strategy. More than 200 scientists from 66 research institutes and more than 25 countries are taking part – not only is CEH among those helping to organise the event, along with Belgian lead organisers INBO, we also have scientists speaking during the main programme, and have organised some of the side events.
The location for the conference is an Augustinian monastery, probably an ideal place to “retreat” to for focused thought and discussion (the whole conference lasts for four days).
Outcomes
The conference recommendations will be presented to EU policy makers and it is expected they will form a starting point for the European Platform on Biodiversity Research Strategy (EPBRS) meeting to be held under the Irish EU Presidency in Dublin in May.
Why an EU 2020 Biodiversity Strategy?
After the overall failure of the previous European strategy to halt the loss of biodiversity by 2010, the EU adopted a new strategy in 2011, with a 2050 vision and a 2020 headline target. This 2020 target was defined as:
"Halting the loss of biodiversity and the degradation of ecosystem services in the EU by 2020, and restoring them in so far as feasible, while stepping up the EU contribution to averting global biodiversity loss."
The EU 2020 Biodiversity Strategy includes six mutually supportive and interdependent targets that respond to the objectives of the 2020 headline target:
1. Conserving and restoring nature
2. Maintaining and enhancing ecosystems and their services
3. Ensuring the sustainability of agriculture, forestry and fisheries
4. Combating invasive alien species
5. Addressing the global biodiversity crisis
6. Contributions of other environmental policies and initiatives
In a series of workshops, groups of scientists and policy makers will discuss the targets, before presenting their recommendations during the final plenary session on Thursday afternoon (April 18 2013).
More about the conference can be found on the ALTER-Net website. Dr Terry Parr from CEH was one of the speakers during Tuesday morning's plenary session on  "Biodiversity, ecosystems and sustainability - how to maintain, enhance and convince in the future". Others taking part in the session included the Finnish research institute SYKE, IRSTEA of France, the European Commission's DG Environment, and the University of Paris-Sud. On Wednesday, Dr Helen Roy of CEH will take part in a session focused on invasive alien species, while on the same day Dr Andrew Sier of CEH leads a side event which will look at developing new initiatives for ALTER-Net to undertake.
Get updates from the event on Twitter using #ALTERNetConf. More information on CEH's international collaborative work can be found on our main website.

Invasive Alien Species: From Data to Decisions

Guest blog by Dr Helen Roy, Ecological Entomologist at the Centre for Ecology & Hydrology, who is a coordinator of the DAISIE (Delivering Alien Invasive Species Inventory for Europe) project.
Invasive Alien Species (IAS) pose a major threat to biodiversity, society, human-health, well-being and the economy. In Europe the economic impact is estimated as 12.5 billion eurosbut extrapolated costs suggest it is over 20 billion euros annually.  Europe has committed to tackling IAS through the recently published EU Biodiversity Strategy to 2020.
Over the next three days (12-14 September 2012) scientists will gather at Neobiota 2012 (taking place in Pontevedra, Spain) - a conference dedicated to research on invasive alien species.  The theme of Neobiota, from data to decisions, provides a perfect context for providing an update on DAISIE (Delivering Alien Species Inventories for Europe). 
DAISIE is an online database providing information on alien species in Europe.  It is unique in many regards.  It is the most comprehensive database on alien species providing information on more than 12,000 alien species**.  It also represents a community of dedicated experts committed to addressing the threat of invasive alien species through the provision of high quality and relevant information available for all.

DAISIE is maintained by the NERC Centre for Ecology & Hydrology (CEH) but relies on collaboration with many alien species experts across Europe to ensure it remains current.  The time, commitment and enthusiasm of the DAISIE alien species experts is inspiring.  So it is with a sense of pride that Jan Pergl (Institute of Botany ASCR, Czech Republic) and I will relaunch DAISIE at Neobiota today (12 September). 
We will have an opportunity to reflect on the many successes of DAISIE, from peer-reviewed publications and books, to the major part DAISIE has played in contributing to strategies on invasive alien species over the last few years.  It is also a time to look forward and to highlight the future role of DAISIE as an information system that will both underpin effective decision making across Europe and provide a rich resource for researchers and invasion biologists. 
We look forward to welcoming new alien species experts to the DAISIE community and invite them to contribute to this impressive database.

** What is an alien species? Alien species, also known as exotic, introduced or non-native species, are species, subspecies or lower taxon occurring outside of the range they occupy naturally or could not occupy without direct or indirect introduction or care by humans. Although the majority of alien species cause no harm, some alien species spread very rapidly and can harm biological diversity, human health, and/or economic and aesthetic values. These harmful species are called invasive alien species. More information at DAISIE.

The impacts of invasive species

News emerged this week linking the presence of invasive Burmese pythons with a severe decline in mammal populations in the Everglades national park in Florida. The scientific study, led by US scientists and published in Proceedings of the National Academy of Sciences, suggests the pythons have had a remarkable impact within just eleven years of their establishment as an invasive species in the 1.5 million acres park. In some areas, foxes, rabbits, raccoons and opossums have all but disappeared and the pythons have also been recorded as consuming deer and alligators. In their native habitats they predate animals the size of leopards.

  The pythons in question are obviously large creatures with appetites to match and the scientists are working to understand how they influence community structure in complex ecosystems. Scientists in the UK are doing similar work, although our invasive non-native species generally influence the environment on a smaller scale. Well known examples that regularly appear in the UK national press include Grey squirrels, the Harlequin ladybird and Himalayan balsam.

Through one such project, Recording Invasive Species Counts , scientists hope to improve their understanding of the ecology and distribution of a number of species recognised as invasive, non-native species that are now established in Britain. It is co-ordinated by the National Biodiversity Network and the Biological Records Centre (part of CEH), in partnership with recording schemes for the animals and plants. (The project is funded by Defra).

The RISC project encourages members of the public to send in their sightings of a number of different species including muntjac deer, the chinese mitten crab and signal crayfish. While Britain has a great tradition of biological recording with well-established monitoring schemes for many different taxonomic groups, non-native species are under-recorded because in many cases they have not been the primary interest of researchers. We would encourage you to help change that by sending in your sightings! The evidence will prove valuable in the future, not just for ecologists but anyone with an interest in managing or enjoying the environment.
