SEEN 1.7

Dear all,
Please have a scroll down and click on any links that you find interesting. Now that term has started I’m expecting a lot of links to be sent in! It doesn’t have to be articles, you can send in links to interesting websites or you-tube clips.
Reminder – Date for your diary
For the last 2 years recent SBS graduates have been involved in collaborative projects with Southampton City Council and Hampshire & Isle of Wight Wildlife Trust. The findings from this year’s projects will be presented onWednesday 9th February from 2pm in Building 32/1015. The projects being presented are:
– the effect of lighting on Southampton Common on bats
– monitoring the great-crested newts on Southampton Common
– comparison of methods to enhance bumblebee diversity in agricultural environments
– comparison of artificial reptile refugia
– the extent and management of invasive non-native plants in the New Forest.
Involvement in the scheme has greatly enhanced the career prospects of previous researchers. Third years, please attend as we will be looking for researchers to continue the monitoring projects from June.
First and second years, you should also attend to find out more about volunteering, work experience, work placements and third year project opportunities with local organisations. Although graduation may seem a long way off employers will be interested to see what experiences you have gained at university, apart from your degree. It may also help you to decide on a career path after graduation.

  • A Slime mould that is a farmer – slime moulds are amazing social amoebae which take on different forms (no one really knows how this is controlled). One type has been found to harvest bacteria rather than hunt it.

        Cuckoos are also responding to climate change by changing the species of bird they egg-dump in.
        Avian brood parasitism involves many traits, so switching host is only selected for when there is an adaptive advantage.
        This study does not look at climate change but shows just how good cuckoos are at manipulating their hosts
        You can read a quick guide to vocal mimicry in Current Biology here: http://download.cell.com/current-biology/pdf/PIIS096098221001451X.pdf
        In another study on parasites, gut microbes have been found to influence the behaviour of mice. The proposed mechanism is that the microbes alter the    expression of a gene which is involved in the production of serotonin, whose site of action is the brain, therefore having neurological and resultant    behavioural effects.

  • From Lex, a mutualistic relationship between bats and pitcher plants – it seems the pitcher plant isn’t as carnivorous as originally thought as it feeds on bat faeces in return for providing a roost for tiny bats
  • We hear quite a lot about the trade in exotic wild animals (go to the CITES website to find out more). However, there is also a trade in rare plants. These plants are rare in their natural environment but may no longer be rare elsewhere due to horticulture. The production of hybrids may also threaten rare plants in their natural environment. Read more about the state of things in the US here:http://www.nature.com/nature/journal/v469/n7331/full/469465a.html
  • Studying deforestation – in Malaysia the upcoming replacement of forest with an palm oil plantation is being studied every step of the way. All aspects of the ecosystem will be studied, to see whether palm oil is a “green” way to boost the economy. What do you thin? There are comments for and against at the bottom.   http://www.nature.com/news/2011/110128/full/news.2011.56.html
  • Breaking evolutionary law – a study published in Evolution suggests that traits once lost may evolve once again, breaking Dollo’s law.
  • Orangutan genome reveals details about human divergence from other great apes, and the evolution of the chimpanzee
Careers
  • Lex emailed 2nd year students with a project opportunity:
Dear 2nd year biologists and zoologists,
I’ve been made aware of an opportunity to do your 3rd year research project on butterflies on Alderney. This might be the perfect opportunity for an ecologically-minded student who would like to do field work, but for whatever reason has decided not to go to the tropics.
If interested, please contact Mel Broadhurst (ecologist for the Alderney Wildlife Trust) directly:
Cheers, Lex
  • There is funding available for Biology-related travel from the Society of Biology: The Society of Biology is offering generous student fellowships for overseas travel connected to biology. The £500 awards are open to Student Associate and Associate AMSB member of the Society, non-members can apply providing they have submitted a fully paid application. Student membership costs just £23 and members receive a number of benefits including access to journals, events and networking opportunities. The fellowships provide an excellent opportunity for students to pursue biological study, teaching or research overseas. Full details are available on their website – http://www.societyofbiology.org/education/careers/travellingfellowship
Species of the week
For Joel, the army ant Eciton burchellii. It’s estimated that around 300 species actually *depend* on E. burchellihttp://www.springerlink.com/content/73352r3v38605u6g/fulltext.html
Looking forward to hearing from you!
