A new research monologue has been published co-written by Professor Nick Gray, a member of the Botany Department. Microbiology of Waterborne Diseases: Microbiological Aspects and Risks is published today by Academic Press, New York (ISBN: 9780124158467). The book reviews current knowledge on drinking water pathogens highlighting their microbiology, clinical features, survival in the environment, risk assessment, and their control. The book is co- written by some the leading researchers in the area: Steve Percival (Honorary Professor of Microbiology at the University of Liverpool and at the University of West Virginia), Marylynn Yates (Professor of Environmental Microbiology at the University of California, Riverside), David Williams (School of Dentistry, at Cardiff University) and Rachel Chalmers (Director of the Cryptosporidium Reference Unit, Public Health, Wales). The book is divided into sections covering bacteria, protozoa, and viruses. Other sections detail methods for detecting and identifying waterborne microorganisms, and the ways in which they are removed from water, including chlorine, ozone, and ultraviolet disinfection. Professor Nick Gray has written two of the six key sections dealing with the control of pathogens and the impact of global warming and climate change on waterborne diseases.Steven Percival

A free conference on Agriculture and Future Weather Patterns is being held in the Teagasc Food Research Centre, at Ashtown, Dublin on Thursday the 5th December 2013.
The government has set ambitious targets for Irish Agriculture under the banner of Food Harvest 2020, with a 50% increase in milk production targeted along with an increase in the output value of beef by 40% and sheep by 20% by 2020. While this is good news for the agricultural sector achieving these goals is very dependent on how our climate is going to evolve. The fodder crisis during the winter and spring of 2012-13 is a good example of how production and weather are linked. This free conference will:
- Update stakeholders on the most current assessments of climate and future weather volatility
- Provide an assessment of the impact of the recent fodder crisis on agriculture and lessons learned
- Unveil exciting new research in monitoring grass growth and providing decision -support
- Identify stakeholder needs in terms of building on-farm adaptive capacity
There is no charge for the conference, but registration is essential. To register please email your name, organisation and contact details to: firstname.lastname@example.org

|Charlotte Darling, who currently works with the |
Bureau of Land Management in Wyoming,
In a major article in US News the problem of the lack of fully trained botanists and the impact that this will have in so many areas from agriculture and forestry to biofuel production is explored. The lack of plant scientists will severely hamper our ability to tackle global warming and adapt to climate change. What is clear is that we need to further develop and invest in Plant Sciences as an academic subject in order to be able to cover all the important areas it underpins and develop the research based solutions that we need for food, fuel and climate security. The article explains that the current trend is to make Plant Science a minor subject in larger and less specialized biological sciences courses which seems crazy if Governments and universities take these issues seriously. For us to train the very best plant scientists they need to be part of research led botany departments and for that to happen universities have to wise up about future priorities and quickly.

Intensive agricultural practices can be responsible for the loss of farmland biodiversity, and have knock-on consequences for the delivery of ecosystem services which benefit humans. Recent research as part of the SIMBIOSYS project, led by Jane Stout in the School of Natural Sciences and Trinity Centre for Biodiversity Research, has quantified the effects of growing bioenergy crops on biodiversity and ecosystem services in Ireland. PhD student, Jesko Zimmermann, working with Prof Mike Jones, showed that even just two years after planting Miscanthus (a fast growing perennial grass grown for biofuel), a significant amount of carbon was already sequestered into soils (published in Global Change Biology Bioenergy). Furthermore, contrary to expectation, planting Miscanthus did not lead to significant losses in existing soil organic carbon stocks (published in European Journal of Soil Science). Jesko’s work also showed that within-crop patchiness of Miscanthus has a significant impact on payback time for initial investments by farmers and might reduce gross margins by about than 35% (published in Global Change Biology Bioenergy). Another PhD student, Dara Stanley, working with Jane Stout, investigated the effects of energy crops on pollinators and pollination and found that exclusion of pollinators from oilseed rape resulted in approximately 30% decrease in seed number and weight, equivalent to nearly €4 million per annum (published in Journal of Insect Conservation). Furthermore, Dara’s work showed that a wide range of pollinating insects use bioenergy fields (published in Journal of Applied Ecology) and that bees from more than 800 bumblebee colonies are attracted to individual oilseed rape fields (published in PLoS ONE). These studies, together with others by post-docs Jens Dauber and David Bourke who also worked on the SIMBIOSYS project, have substantially advanced understanding of the interactions between bioenergy crops and farmland biodiversity. The final report of the EPA-funded SIMBIOSYS project is available here.

|The 2013 Plant Science undergraduates|
Each year the incoming junior freshmen (third year students) have introductory field course to learn some basic techniques, as well as to get to know each other. This year it was based in and around the Wicklow Mountains National Park and was enjoyed by students and staff alike. The first few days were filled with bright sunshine and that made the excursion to, and work on, Liffey Head Bog (the source of the River Liffey) very pleasant indeed: in fact it was almost too hot. The field work was combined with two overnight stays in Glendalough allowing the woodlands nearby to be investigated as well as the local pubs! Later days were spent at Avoca exploring the mining area and on the coast at Bull Island looking at estuarine and sand dune vegetation and some of the management issues dealing with a nature reserve right in the centre of the City.

There isn’t much you can tell plant science researcher Jesko Zimmerman about the biomass crop Miscanthus or elephant grass. It is widely grown throughout the EU as a commercial energy crop, which can be used for combined heat and power generation or converted into biofuel such as ethanol. However, according to Jesko, bioenergy crops put us into somewhat of a dilemma, or a trilemma as David Tilman and colleagues put it in their noteworthy 2009 paper in the journal Science, ‘Beneficial biofuels -the food, energy, and environment trilemma’. The interesting conclusion of that paper being that bioenergy can work, if it is done right.

This raised three questions that Jesko is very interested to finding answers to: (i) Why are they not growing in these areas, (ii) how much yield is being lost, and (iii) how is the economic feasibility of growing Miscanthus affected?
As no yield data was available for these fields, we had to measure the amount of cropped area (and therefore yield) lost due to patchiness using aerial photography, which showed an average reduction in biomass yield of 13.7%. The economic loss was calculated using life-cycle assessment tools to compare the gross margin for each field if the full potential yield is realised and if yield loss due to patchiness is taken into account. The results showed that farmer’s gross margins were reduced by up to 35 %. The question what caused the patches has not been directly answered. However, the aerial images do give some indications. Miscanthus rhizomes are directly planted into the soil and parallel lines of linear patches indicate problems while planting the crop due to jamming in the mechanical planter, which has been confirmed by farmers. Single large patches indicate localised issues such as areas of water logging while widely spread small patches appear to originate from planting rhizomes that did not survive storage. Generally it could be shown that patchiness may not be an immediate problem for farmers, but that addressing the issue could have significant economic benefits. While the cause of patchiness was not directly investigated, it can be said that taking more care when planting should reduce the crop patchiness. More details of this can be found in Jesko’s recent paper in Global Change Biology Bioenergy. ‘Assessing the impact of within crop heterogeneity (‘patchiness’) in young Miscanthus × giganteus fields on economic feasibility and soil carbon sequestration’.

|Cambodia's forests are under constant threat of deforestation|
The first lecture is by Professor Ida Theilade who is Senior Researcher at the University of Copenhagen’s Centre for Forest, Landscape and Planning. She is also a member of IUCN Species Survival Committee on threatened trees. Her talk is on Evergreen forest types in Cambodia: floristic composition, ecological characteristics and conservation status. Even if you are unsure about plants, then this will give you an interesting insight into biodiversity and conservation and the images are going to be fantastic. She also works on the REDD process (reduced emissions from deforestation and forest degradation) with focuses on how to design projects to benefit not only the climate but also biodiversity and forest dependent people. Like many other countries conservation of forests is a very politicized issue, so this will be a very interesting insight into the problems that surround it.
Talks take place every Friday afternoon in the Botany Lecture Theatre at 3 pm starting on the 4th October with tea and cake afterwards. I know you might be a bit nervous about just turning up...but YOU are very welcome to come along and we especially would love to meet and talk to any new students. If you need some more information contact email@example.com

The quick answer is that we need the very best people to become plant scientists in order to address the most serious and challenging problems facing mankind and the global ecosystem.
Plants provide us with food, biofuels, fibre for clothing, and medicines. They provide us with shelter, buffer us from extreme weather, regulate the oxygen balance in the atmosphere and sustain our global diversity. In fact plants sustain all life on Earth. The challenges thrown up by global warming and a rapidly developing population, set to hit between 10 to 12 billion by 2050, will be solved largely by plants and that means plant scientists.
Currently we are desperately short of plant scientists and for that reason they are among the top science earners coming after doctors and dentists in terms of average starting salary.
The opportunities are enormous allowing you to specialize in biochemistry, physiology, genetics, systematics, conservation and many more areas, in fact plant scientists are to be found working at the forefront of all science areas. So whether you enjoy lab work or being outdoors, developing new products, growing food or biofuels, whether its research or business, plant sciences can offer you enormous opportunities. New industrial initiatives using plants include anti-cancer drugs, biodegradable plastics, biodiesel from algae, healthier sugars, that’s not to mention advances in cereal and crop production, as well as forestry, all developed by plant scientists. Plants offer us sustainable alternatives to feeding the global population and dealing with climate change. Are you up for the challenge?
If interested why not have a look at this list of 100 important questions that urgently need to be addressed by the next generation of plant scientists. This list was drawn up by scientists from the Royal Botanic Gardens, Kew, the John Innes Centre, the Natural History Museum, the Royal Horticultural Society, universities, agriculture and industry. Perhaps with more plant scientists we really can make a difference and really tackle hunger, poverty and climate change. Have a look at some of our past students or make an appointment to talk to one of us.
