Please follow the link below for more details about the London Freshwater Group meeting, March 18th 2016. A programme packed with fab freshwater talks, including one about Lake BESS by Ambroise Baker.
And a link to the Group’s website.
All our readers will be interested in this new research project in which all Lake BESS researchers are involved. We will be taking freshwater landscape-scale conservation into a whole new level!
Hello! This is the first of many blogs from the scientists behind a multi-million pound NERC funded project studying the interactions between connectivity and stressors in freshwater habitats.
We are blogging from our first meeting involving all collaborators on the project at CEH Lancaster (conveniently located halfway between Stirling and London).
We don’t have breaking scientific discoveries just yet, but have been discussing how to best implement and coordinate our study across Britain and efficiently use our areas of expertise.
Stay tuned for news of new team members, where and what we’ll be sampling and general freshwater related musings.
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.
We are inviting any interested Broads stakeholder to take part to our workshop on Lake Connectivity, Biodiversity and Ecosystem Services in the Broads, England.
At this occasion, we would like to share the findings of our Lake BESS research project and we will have a special focus on the Broads. We are keen to share our work with local stakeholders working on and around lakes in the area so our research can be useful to anyone concerned.

Following the previous post, this is just to let you know that our trip to Northern Ireland was very successful. It gave us a chance to discuss our research results with many partners, stakeholders and members of the public. The interest we met makes us hope that our research will find direct applications on the ground.
We would like to thank the many people who made this trip possible at the Fermanagh and Omagh District Council, Waterways Ireland, the Northern Ireland Environmental Agency and Queen’s University Belfast.
We are organising two events in Northern Ireland to share our results with local stakeholders.
For both events there will be a presentation of our results and plenty of time for Q&As and discussion.
We would like to share our research findings with local stakeholders working on and around Upper Lough Erne’s satellite lakes so our research can be useful to those most concerned.
Please let us know if you would like to come by email: ambroise.baker [ at] ucl.ac.uk or with a message at the bottom of this page; and do not hesitate to forward this invitation to anyone you think could be interested.
The BBC reported today that Fermanagh is the happiest place in the UK according to a recent survey by the ONS. Is there a link with the exceptional freshwater biodiversity levels we found during our work in the Upper Lough Erne region, part of Co. Fermanagh? Our Lake BESS work is only a preliminary step towards answering such fundamental question: a whole new research agenda lies ahead of us to better understand the value of nature and ecosystems in what is often referred to as coupled human-environment systems.
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.
Our 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:
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.
The 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!
The 100th ESA annual meeting was a great experience! It was an opportunity to present our work, of course, but what I really enjoyed was the breadth and depth. The breadth of ecological topics represented was exceptional – speak about biodiversity!- and the depth of the talks and of the understanding within each subfield was phenomenal.
I would like to highlight three researchers and their talks. There were many other remarkable ones but these actually tie well together in what I would call a list obstacles for our societies to deal effectively with the biodiversity crisis and with ecological issues in general.
Stephen Jackson from the University of Arizona, USA, presented five major challenges for ecology. Among those, three could be labelled as governance challenges within ecological research – whether within academic institutions or in the way academics interacts with decision makers and land managers.
Two others were more directly related to our science. Stephen notably put an emphasis on the difficulties related to defining nature in a context of ever-changing conditions – and in a context of omnipresent human pressure.
This last point was further developed by Jens-Christian Svenning from Aarhus University, Denmark. It was divided into three categories: disequilibrium dynamics, novel ecosystems and trophic cascade. These three ecological phenomena remind us how much ecosystem function in a complex way. As a result of this complexity, ecosystems have futures that are extremely difficult, if not impossible, to predict.
Jens-Christian presented several compelling examples to illustrate his talk and I would refer anyone interested to his publication list.
Finally, Shannon Hagerman, from the University of British Columbia, Canada, provided a wider framework explaining the origin of these institutional and ecological challenges.
Shannon’s work focusses on the values underlying expert opinion in biodiversity science and claims that today’s novel impact created by human activities not only threatens biodiversity in a direct way (as we all understand it) but it also deeply questions the values that have hitherto guided conservation actions.
It can be postulated that this crisis of values within the field of conservation at large creates obstacles for us to deal effectively with the biodiversity crisis itself and with ecological issues in general.
This is a very simplified synthesis of these three talks, that certainly does not do them justice, and the opinions expressed are mine. Ambroise, Sheffield, UK, August 27th 2015
The BESS resilience workshop on June 18th and 19th was a great success with over twenty attendees, mostly BESS researchers but also JNCC and Welsh government representatives.
We also had two special guests, Volker Grimm and Hanna Weise from the Helmholtz Center for Environmental Research, Leipzig, Germany, who presented fascinating background information about ecosystem resilience. Volker was a pioneer in trying to understand how the notion of resilience can be applied in ecology and his 1997 seminal paper is worthwhile a read.
The first day’s discussions were focussed on defining resilience, while in the second day we explored the multiple ways that can be used to measure ecosystem resilience.
It was very enlightening to hear different researchers from different BESS projects explain how ecosystem resilience was relevant to their work. The diversity of opinion was absolutely overwhelming! To such an extent that after two days of lively discussion it became very difficult to produce a short summary or a take-home message.
There was however two important points most attendees agreed upon:
