WTT Blog - Tagged with salmonid

A part of Jonny Grey's role as a Professor in Practice is to forge links with the academic community and facilitate research projects. It was serendipitous timing last year when Lizzie Thomas contacted WTT, asking if we had any data relating to our numerous restorations - Jonny's 'TROUT project, Tackling Resilience On Underperforming Tributaries, was just beginning to bear fruit. Lizzie is a Zoology graduate from the University of Southampton and has just completed her MSc research in Ecology, Evolution and Conservation at Imperial College, London. She was particularly interested in understanding the effects of habitat restoration on salmonids given their ecological and economic value and, here, summarises the findings from her thesis.

NoWPaS, the International (formerly Nordic) Workshop for PhD and post-doctoral fellows working on anadromous Salmonids, is an annual workshop which consists almost entirely of early career researchers (ECRs) with a focus on PhD students. The workshop, which is organised by a committee of PhD students, allows a small group ECRs to present their research programme and ideas, along with any results that they might have already collected. WTT Research & Conservation Officer, Jonny Grey, was our man in the thick of it at the NoWPaS 2019 meeting, held at the Scottish Centre for Ecology and the Natural Environment (SCENE), the University of Glasgow’s field research station.

Quite a few of our guest bloggers recently have been at the same conference. Unfortunately, I could only follow the key scientific revelations via Twitter from afar but I have been alerted to some work of which I was previously unaware, so I am hoping to establish contact with those people and perhaps they will contribute a blog or two in the near future. Here, Jess Marsh (she of the water crowfoot and salmonid community research) has kindly offered to tell us briefly about NoWPas.

A week after the 14th annual NoWPaS workshop was wrapped up in spectacular style with a traditional Finnish nuotio, or campfire, we are reflecting on an inspiring week of exciting salmonid research, new experiences and friendships.

'Tis the season to bash balsam - if you don't know how to, check out the definitive guide from WTT chum, Theo Pike, for guidance! Timely then for a new blog focussing on invasive plants. Alex Seeney from the Centre for River Ecosystem Science (CRESS) at the University of Stirling, is battling with balsam and knotweed from a more academic angle, and below gives an overview of some his research to date. This valuable work is supported by Scottish Natural Heritage.

Some of the most diverse and complex habitat types in aquatic systems are found at the interface between terrestrial and aquatic communities – the riparian zone. These diverse, dynamic systems provide an ecologically important buffer between land and water, and as such they are of particular importance to the health and quality of the waterways they border.

Asa White gets to call wading around in the Bourne Rivulet work! Our research interests in chalk streams have some parallels. While I am curious as to how a colourless, odourless gas (methane) contributes to the fuelling of their food webs, Asa is trying to understand how an equally invisible chemical is affecting invertebrate and fish life. Here, he outlines his research plans and offers up the experience of electric fishing - read on! 

Watercress is native to the chalk streams of southern England, and has been harvested for millennia. In the early 19th century, the advent of the railway made commercial production viable for the first time. A growing London market supplied by trains (the famous ‘Watercress Line’ being one) led to an explosion in the number of watercress farms throughout the south of England. Historically, watercress was grown in gravel beds irrigated by water diverted from chalk streams, but hygiene concerns now oblige growers to irrigate their beds using fresh water abstracted from boreholes. In both instances, the water used to irrigate the beds is discharged into adjacent chalk streams.
