Felix Eissenhauer, a PhD student at the University of New Brunswick, will be giving a seminar entitled “Ecology of the American eel (Anguilla rostrata) in a large tidal and hydropower-regulated river” over Zoom  https://kau-se.zoom.us/j/65816884688 at 13:15 CET on December 5, 2023.

Felix’s work focuses on the ecology of the American eel in the Wolastoq River, a large tidal and hydropower-regulated river in Canada. He is studying how a hydropower dam affects the recruitment of eel elvers and using mark-recapture methods to assess their population size and demographics. Further, Felix uses acoustic telemetry to study the depth and thermal habitat use and the seasonal migration behaviour of yellow eels in the Wolastoq River.

You are welcome to join this seminar

On Tuesday, 6th December at 14:15 CET, David Aldvén from Vattenfall AB will be giving a seminar about Hydropower and biodiversity. This will be live over zoom (https://kau-se.zoom.us/my/kaubiology) and on KAU Campus in Room 5F416. You are all invited to attend.

Johan Watz (Associate Professor at University of Karlstad Biology Department) together with others from the department, DHI Sverige and Fortum Sverige have recently published an article with VATTEN- Journal of Water Management and Research. The article, entitled ” HOW MUCH WATER DO SEA TROUT NEED? A COMPARISON BETWEEN A CORRELATIVE AND AN INDIVIDUAL-BASED MODEL TO PREDICT EFFECTS OF FLOW ON STREAM FISH POPULATIONS” used both a correlative model and an individual-based fish habitat model called InSTREM 7 as a management tool to assess water requirements for salmon and trout in a river reach located below Blanka-ström hydropower plant in river Emån, Sweden.

Jacqueline Hoppenreijs, Lutz Eckstein and Lovisa Lind have a new paper out! It describes the different pressures of human activities on boreal riparian vegetation. They collected information from 182 scientific papers, books and reports and found that there are factors that are already damaging many rivers, such as hydropower (Figure 1), and factors that will become more important in the future, such as the climate crisis. More importantly, they found that these and other processes interact in ways that we don’t understand yet, simply because they’ve hardly been studied.

They combined all the effects of the pressures in one conceptual model (Figure 2), to help researchers, managers and everyone else who might be interested to ask more relevant research questions and balance different management measures with each other, so that riparian zones and the land and water around them can be protected better.
