Workshop in the Broads

Lake BESS research on the importance of water connectivity for healthy shallow lakes in the Upper Lough Erne, Northern Ireland and in the Broads, England, was presented to the Broads stakeholders yesterday. The event hosted by the Broads Authority.

This was an opportunity to discuss how our research will be translated into actions in the Broads where multiple major restoration projects are happening.

Carl Sayer gave an inspirational talk comparing the lake ecology and aquatic vegetation of the Upper Lough Erne region and The Broads.

Lake BESS preliminary results presented in Liverpool

Here is a short summary of the talk we gave yesterday, at the Aquatic biodiversity and ecosystems conference held at the University of Liverpool, where we asked the question: Does connectivity between lakes enhance biodiversity resilience to eutrophication in the Upper Lough Erne area and in The Broads? A talk based on the same research was delivered in Baltimore, USA for the 100th Annual Meeting of the Ecological Society of America – see this post.

methods in the fieldOur data was a compilation of lake surveys in both lake districts and for two time periods: the 1980 and recent time (thanks you to all our partners who were willing to share their data, by the way!). Each lake survey comprises of:

  • Extensive botanical work, recording aquatic plants from the open water and the marginal zone, and
  • Collecting water samples that are later analysed in the lab for phytoplankton abundance, concentration of nutrients such as phosphorus and water chemistry in general.

Our data shows that nutrient pollution drives ecosystem functioning in both regions and during both time periods. This reminds us on the importance of good policies to protect freshwaters while maintaining thriving agriculture.

phtoplanktonThe situation with biodiversity is a bit different as it appears to be influenced both by the local conditions (lake size and shape, nutrients status) and landscape-wide connectivity. One main difference between the Upper Lough Erne lakes and the Broads is that flood connectivity in the Upper lough Erne is a major factor structuring in the aquatic plant communities there. Does this induce greater resilience? remains a pending question we are working on.

All these results are being written up into a scientific article, so please get in touch if you’d like to discuss or report them!

Lake BESS to present results: 100th Ecological Society of America annual meeting, Baltimore, USA

Lake BESS is looking forward to going to the 100th Ecological Society of America (ESA) annual meeting in Baltimore! We have a talk scheduled Friday August 14th 2015 during the session “COS 142: Habitat Structure, Fragmentation, Connectivity”.logo

This is a very exciting opportunity to present our work asking the question: Does connectivity increase resilience of biodiversity against eutrophication in networks of shallow lakes? Our talk will be the only one focusing on freshwater in an collection of oral papers otherwise dedicated to ecological connectivity.

We will be using aquatic plant surveys conducted between 1983 and 2014 in our two study areas: The Broads, England, UK, and the Upper Lough Erne area, Northern Ireland, UK, and we will identify the relative importance of:

  • connectivity between lakes,
  • local water chemistry
  • lake morphology
  • and other factors

to explain the aquatic vegetation patters in the two lake districts during two time periods.

The comprehensive programme of the conference is available here online program and our abstract can be read there.

UK and Ireland Lakes Network conference 4th-5th March 2015

The UK and Ireland Lakes Network meeting was taking place in Abergavenny, South Wales, yesterday and the day before. This was a great opportunity for Lake BESS to meet other people working with lakes, hear about their activities and introduce our research.

In addition to many inspirational talks, we got very insightful feedback regarding our research project, following Ambroise Baker’s presentation. Thank you to Catherine Duigan from Natural Resources Wales for sharing this picture tweeted during the conference.
