PDRA: molecular approaches for building highly-resolved networks

Postdoctoral Research Assistant (Ecology & Evolution)

Reference: 

FS0065

Campus: 

Hull

Faculty/Area: 

Faculty of Science and Engineering

Department: 

School of Biological, Biomedical and Environmental Sciences

Salary: 

£31,331 to £36,298 per annum

Post Type: 

Full Time

Closing Date: 

Friday 20 December 2013

We wish to appoint a suitably qualified and experienced Postdoctoral Research Assistant to develop molecular approaches for understanding forest insect community dynamics and species interactions.

The PDRA will work jointly with the Biological Conservation (Dr. Darren Evans: tinyurl.com/oxjfuhf) and Evolutionary Biology (Dr. Dave Lunt: davelunt.net) Groups within the School of Biological, Biomedical and Environmental Sciences and with Forest Research, the Research Agency of the Forestry Commission (Dr. Nigel Straw). The post is funded by Forestry Commission England and the successful candidate will develop molecular approaches to determine forest insect host-parasitoid interactions with a particular focus on oak processionary moth (OPM; Thaumetopoea processionea), an invasive species that is highly damaging to oak trees and which poses health risks to humans.  The PDRA will join a successful team using sensitive molecular tools to construct and analyse highly resolved species interaction networks. The successful candidate will benefit from excellent research facilities and a dynamic research environment within the two closely interacting groups.

A primary goal of the project is to employ DNA barcoding to identify the hymenopteran parasitoids of OPM and shared hosts. Potentially these could be harnessed as a natural form of pest control. The structure of these food-webs will be analysed using ecological network analysis. The application of evolutionary and environmental genomics is a research strength of the groups and there is considerable scope for the PDRA to develop next generation sequence (NGS) meta-barcoding approaches to characterise forest community composition more broadly.

The successful applicant will collaborate closely with Forest Research and other partner organisations and will be supported in developing independent fellowship proposals. He/She will have a PhD in an appropriate biological discipline, substantial experience in molecular ecology, strong quantitative skills, evidence of work of publishable quality, excellent oral and written communication skills, demonstrable ability to work as an effective team member and be reliable, self-motivated and well organized. Experience of NGS analysis and ecological network analysis using R is desirable, but not essential.

Interviews are anticipated to be held in mid January.

The position is fixed term for 2 years.

 To discuss this role informally, please contact Dr Darren Evans, E d.evans-Cu7FvJMYcQGHXe+LvDLADg@public.gmane.orgk or Dr Dave Lunt, E d.h.lunt-t9rsHg3KcLk@public.gmane.org.uk

Multiple species traits in freshwater food webs – a new paper

Dear colleagues,


I would like to make you aware of our new paper about the role of species traits for predator-prey interactions in freshwater food webs that is now published in the latest issue of the Journal of Animal Ecology. You can download the paper here:


https://www.researchgate.net/publication/250920991_Foraging_and_vulnerability_traits_modify_predator-prey_body_mass_allometry_freshwater_macroinvertebrates_as_a_case_study?ev=prf_pub


We conducted laboratory experiments with a range of predatory aquatic insects and their prey and found that the strength of predator–prey interactions depends not only on predator and prey body size but also on their foraging and vulnerability traits. We quantified these effects by fitting recently developed multiple-trait food web models of Rossberg et al. (2010) and Rohr et al. (2010). Our results imply that the inclusion of multiple species traits could help us predict interactions strength in food webs more accurately than solely on the basis of body mass.


Klecka J. & Boukal D.S., 2013: Foraging and vulnerability traits modify predator-prey body mass allometry: freshwater macroinvertebrates as a case study. Journal of Animal Ecology 82: 1031–1041.


Best regards,

Jan Klecka

Update to Release of GoMexSI ver 1.0

Hi to all,

  First, I want to thank all of you who have emailed and/or visited and registered on the GoMexSI website.  There has been a really great response!!

  It is frustrating that we have so much more data that needs to be served and it just takes a lot of time to extract, edit and post it. Please be patient.

  Some updates:

                We have added 1,438 predator-prey interactions to the database since Sep 3rd  as a result of our NOAA IEA funding – more is on the way shortly.

                We have recently received notification of funding through NOAA MARFIN (3 yrs) and NOAA CIMAS (1 yr), both of which have data extraction components.

                We have added a large number of people to the email list, either ones that I realized I had missed or from the registrations on the webpage.  Please, if you want to be dropped from this list, let us know.

                In the future we are planning to implement a method to periodically send updates when new data is available or other newsworthy events may have occurred concerning the database/webpage.

Below is the release announcement we sent out one month ago, Sep 3, 2013, for those who have not seen it.

New software release announcement

September 3, 2013 at 1300 PM CDT

The GoMexSI team is pleased to announce the release of the GoMexSI Database and Informatics tool Beta Version 1.0.

While we recognize that we have a long way to go both in data entry and database functionality, we feel it important to announce this release of GoMexSI to a wider audience, thus increasing the visibility of GoMexSI, garnering further useful feedback, and through networking, further increase our visibility.  There are still a number of contributed datasets yet to be added to the database, and a number of enhanced functions that are planned for future releases.

Recently we have added much functionality, including some new features as follows:

  • Predator or prey searches refined by a specific species.

  • Location based spatial queries based on user defined parameters.

  • Raw data downloads in CSV format.

  • Food web visualizations inside of the Exploration mode.

  • Direct links to EOL for each species returned from the query.  

Some features to look for in the next version will include:

  • All text in both Spanish and English.

  • Search by common name, both Spanish and English.

  • More robust CSV downloads with many more data fields.

  • Enhanced spatial query page with locations of available data on the map.

  • Direct links to Fishbase for each fish species in the database.

  • More data!!

  • Response to requests from users, if possible.

Please contact Dr. James Simons for more information or if you are interested in contributing data to GoMexSI.

We would like to thank all of those who have put time and energy into this project, specifically:

If you are interested in any of the software used to support the GoMexSI project, please view our GitHub

 page.

Please pass along this announcement to others you feel may have an interest in the GoMexSI database.

Finally, please provide us with comments, suggestions, or criticisms.

Thanks, the GoMexSI Team!!

New book on food webs

Dear All

I am happy to announce the launch of 

  Food Webs and Biodiversity: Foundations, Models, Data
  Wiley, 396 pages
  http://eu.wiley.com/WileyCDA/WileyTitle/productCd-0470973552.html

The book develops a comprehensive theory of food webs with a special
emphasis on the biodiversity that food webs harbour.  The ideas was to
develop food-web theory from "first principles", i.e., by introducing
a few basic concepts anchored in observations and building the theory
step by step from these concepts.  

One of the surprising results obtained is that species richness
declines by an approximate factor 3 with each trophic level, in
excellent agreement with observations.

Hope you find the book interesting and useful!

Best,
Axel
