I simply can’t wait for the Festival of Ecology in Dec 2020, an all online event that replaces the British Ecological Society’s traditional in-person annual meeting this year. BES events are always a huge source of inspiration with talks from researchers around the World, discussions, and an opportunity to meet with long-time-no-see colleagues.
In addition, this year I am going to present some of my work on megafauna with a 15-mins talk:
Reviving the function of extinct megafauna: inspiration from the past
It was exciting to hear that our abstract was accepted for an oral presentation at this conference dedicated to aquatic plants. The research presented attempted to explain the decline in diversity of emergent aquatic plants in the Upper Lough Erne area, Northern Ireland, UK and related change to landscape connectivity. This presentation was supported by NERC through my two postdoc projects, Lake BESS and Hydroscape.
BESS – Biodiversity & Ecosystem Services Sustainability – was a £15M 2011-2017 research programme funded by NERC, the UK research council concerned with the natural environment. This conference was a wrap up event co-organised with the BES, the British Ecological Society and hosted by the Water Research Institute at Cardiff University.
It was a great opportunity to present results from our Lakes BESS project, my first postdoc, and interact with a fun bunch of researchers with similar interests. It was also a chance to learn about the tremendous research advances in the field of biodiversity and ecosystem services achieved by BESS researchers and others.
The most thought-provoking talk was delivered by Kai Chan from the University of British Columbia, Canada. He defended ideas published in his 2016 PNAS paper:
Chan et al 2016. Why protect nature? Rethinking values and the environment PNAS 113 (6) 1462-1465. doi:10.1073/pnas.1525002113
His talk aimed to demonstrate that relational values drive biodiversity and ecosystem services protection, in addition to the commonly accepted intrinsic and instrumental values of nature.
Was the audience convinced? His talked certainly sparked great interest and numerous questions. For sure there is an empty gap to be filled around the classic divide between protecting the environment for its intrinsic value or for very utilitarian reasons. This simplistic intrinsic-instrumental value scheme is simply not sufficient anymore.
However, I remain to be convinced ‘relational values’ completely fill this gap – and even I remain to fully comprehend what is meant by ‘relational values’ – a notion I am not familiar enough with, as an ecologist.
The other outstanding talk I would like to highlight here is that of Elena Bennett from McGill University, Canada. She demonstrated with practical example from work carried out by her lab how ecosystem services can inform multifunctional landscape management.
She also finished her talk by reminding us about the “importance of the contributions of both nature and human action to the provision of services”, i.e. the natural environment does not simply provide us with what we need, quite the reverse ecosystem services also strongly depend on us working with nature, in a co-production.
Many other contributions could be mentioned here, including a whole session dedicated to ecological resilience. Our Lake BESS presentation was well received judging by the positive comments people shared.
My talk title was: Landscape connectivity is important for lake ecosystem function and biodiversity and I am pleased to share slides from the introduction and conclusion:
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.
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:
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.
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!
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”.
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
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.
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.
On Thursday morning, we visited the beautiful Llangors Lake, the largest natural lakes in South Wales. A fab occasion to network away while enjoying the great outdoors!
Thank you to the UK and Ireland Lakes Network and to Natural Resources Wales for organising this conference and giving us a chance to present our work.
