Eyjafjallajökull: Lessons from the Past
The relatively modest eruption of Eyjafjallajökull last year resulted in travel chaos for 10.5 million passengers and cost the airline industry some £1.7 billion. This was the first eruption of Eyjafjallajökull for 190 years and its awakening renewed expectations that its neighbouring volcano, Katla, might well also erupt in the near future. Katla erupts on average twice a century, whilst Eyjafjallajökull has only erupted four times in the past 1500 years. Katla last erupted in 1918 and it is expected that its next eruption will be much larger than Eyjafjallajökull’s. The hazards from such an eruption could include jökulhlaups up to 100 times larger than those seen in 2010 and substantial tephra production. Geomorphological and tephrochronological studies suggest that eruptions of Eyjafjallajökull have coincided with eruptions from Katla. As well as providing valuable information about past eruptions, fluctuations of glacial limits can also be identified. Tephrochronology is an invaluable tool for volcanological, geomorphological and glacial studies in Iceland.

Effects of Insect Pathogenic Fungi and Ectomycorrhizal Fungal Inoculation of Birch Seedlings on the Survival of Otiorhynchus Larvae in Icelandic soils
Icelandic foresters have been charged with increasing forest cover from current levels of around 1.5% to 5% of land area in the next four decades. Forest regeneration involving both non-native conifers and native downy birch (Betula pubescens) is being mainly achieved through nursery seedling transplantation but variable establishment success rates have been attributed to root herbivory by weevil larvae of a number of opportunistic Otiorhynchus spp. (Order: Coleoptera; Family: Curculionidae). With the increasing withdrawal of common chemical insecticides from registration, more sustainable pest control measures are now being prioritised. In order to assess the potential of a novel multi-fungal biological control strategy, experiments involving factorial inoculation of birch seedlings with root symbiotic ectomycorrhizal fungi and the insect pathogenic fungus (Metarhizium anisopliae) in controlled pot experiments and field trials were carried out. Early reductions in root herbivory and improved seedling survival rates detected in single and dual inoculation treatments were found to be also dependent on soil and site characteristics that point to the involvement of further biotic and abiotic factors in pest control success. The data not only highlights the great potential for biological control of these invertebrate herbivores but also the urgent need for a better understanding of multitrophic host-pest-microbe-soil interactions in development of sustainable plant pest control strategies.

theWeather Club £10 offer on World Meteorological Day
To celebrate World Meteorological Day, theWeather Club are offering introductory membership for only £10.
theWeather Club launched by the Royal Meteorological Society last September normally retails at £25, but for one day only you can receive the full range of benefits for only £10.
Being a member of the club will allow you to become part of a community of people for whom the weather is more than just something that happens outdoors. Our members are gardeners, walkers, outdoor enthusiasts, meteorologists, and people who happen to have a close interest in the world around them. The club provides a fantastic source of information about this most fascinating and topical of subjects.
What does membership include?
Membership includes a welcome pack including a copy of the beautiful magazine – theWeather which retails at £4.95, a set of weather postcards; a collectable A-Z of weather and climate; and a Galileo thermometer worth £15. Your membership entitles you to free copies of the quarterly magazine, theWeather, and the collectable A-Z of weather posted out to you, access to exclusive web content and to our members’ forum, plus exclusive offers from partner companies.
Take advantage of this offer by logging onto www.theWeatherClub.org.uk on Wednesday 23rd March and joining online or calling 0118 956 8500.

Sustainability & Global Systems Session this week
Hi all,
I will be 15 minutes late arriving to the start of the 1pm lecture this week.....this is because I am involved in the University Open Day and will not get away from the Geoffrey Manton building until at least 1pm.
Please take a comfort break after Research Design & Methods and we will start the session at 1:20pm
Thanks
Mark
