Trophic niche-space imaging

Dear Colleagues,

Theoretical Ecology just published 

"Trophic niche-space imaging, using resource and consumer traits",
http://link.springer.com/article/10.1007%2Fs12080-014-0229-5

by Leo Nagelkerke and myself. 

A preprint can be found here:
http://axel.rossberg.net/paper/Nagelkerke2014TheoEcol_NicheSpaceImaging_preprint.pdf

In case you fancy trying some "nichespace photography" on your own,
here http://foodwebs.info/NagelkerkeRossberg2014-RCode.zip is a link
to R-code and data files that we used, since for some reason they did
not make it onto the journal page, yet.

Please feel free to contact me or Leo with any comments or questions.

Best wishes,
Axel

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Abstract:

The strength of trophic (feeding) links between two species depends on
the traits of both the consumer and the resource. But which traits of
consumer and resource have to be measured to predict link strengths,
and how many? A novel theoretical framework for systematically
determining trophic traits from empirical data was recently
proposed. Here we demonstrate this approach for a group of 14 consumer
fish species (Labeobarbus spp., Cyprinidae) and 11 aquatic resource
categories coexisting in Lake Tana in northern Ethiopia, analysing
large sets of phenotypic consumer and resource traits with known roles
in feeding ecology. We systematically reconstruct structure and
geometry of trophic niche space, in which link strengths are predicted
by the distances between consumers and resources. These distances are
then represented graphically resulting in an image of trophic niche
space and its occupancy. We find trophic niche to be
multi-dimensional. Among the models we analysed, one with two resource
and two consumer traits had the highest predictive power for link
strength.  Results further suggest that trophic niche space has a
pseudo-Euclidean geometry, meaning that link strength decays with
distance in some dimensions of trophic niche space, while it increases
with distance in other dimensions. Our analysis not only informs
theory and modelling, but may also be helpful for predicting trophic
link strengths for pairs of other, similar species.

Post Doc position Theoretical Community Ecology

Dear collaegues,

I am happy to announce the following position (also attached) and look forward to suitable applications:

Post-Doc Position in Theoretical Community Ecology at Potsdam, Germany

Pending final approval of funding we offer a full time position for 3 years with a potential second funding period of 3 more years at the department of Ecology/Ecosystem Modelling at Potsdam University (German salary scale E 13, 100%). The position is available within the recently established Priority Programme “Flexibility matters: Interplay between trait diversity and ecological dynamics using aquatic communities as model systems” (www.DynaTrait.de) funded by the German Science Foundation (DFG). We are seeking a highly motivated and productive scientist who is interested and capable of contributing to a modelling team closely interacting with experimentalists conducting laboratory food web experiments. She/he should have strong research interests in community and trait-based ecology (e.g. dynamics of predator-prey and multi-trophic systems), and in the role of adaptability for system dynamics in particular (e.g. via eco-evolutionary dynamics). The work includes developing and analyzing predator-prey and food web models which account for ongoing mutual adaptations of trait values among interacting organisms related to corresponding experiments.
The ideal candidate holds a Ph.D., has an excellent publication record in the field of theoretical ecology and ecological modelling and comprehensive skills in working with systems of differential equations. Prior Post-Doc experience, skills in time-series analysis and interest in co-supervising students is highly welcome. The modelling team, consisting of Post-Docs, Ph.D. and Master students, is supervised by Prof. Dr. Ursula Gaedke and Prof. Dr. Horst Malchow (Univ. Osnabrück) and provides a very stimulating research environment for promoting theoretical ecology by modelling and empirical studies. The position may be suitable to strive for a Habilitation. Fluency in English is essential but gaining some control of the German language is expected. Potsdam (near Berlin, Germany) is an attractive town of about 170,000 inhabitants.  It is an UNESCO world heritage and due to its close vicinity to Berlin covers a broad spectrum of all kinds of cultural activities.
For further information please visit http://www.uni-potsdam.de/en/ibb/researchgroups/ fullprofessors/ecology-and-ecosystem-modelling.html or contact U. Gaedke (gaedke <at> uni-potsdam. de). Applications should include a statement of motivation, a detailed CV with the list of publications, contact details of academic referees and degree certificates. Please send them electronically, if possible as a single file, to U. Gaedke. The position is open until it gets filled. The “12-years-rule” does not apply for this position.

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.

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:
