Short film: The hyporheic zone

Posted by Daniel Nyqvist | Nyheter

The hyporheic zone –  the region beneath the river bottom – is home to a wide range of minute life forms and processes of high importance for the ecology of the river. Learn more in the short film Secret Life of Rivers:

John Piccolo, researcher at Karlstad University, recently published an article in Journal for Conservation of Nature about value in natureThe paper is titledIntrinsic values in nature: Objective good or simply half of an unhelpful dichotomy?”. In the abstract John Piccolo writes: ”Two generations of conservationists and philosophers have built a strong case for intrinsic values in nature; they are the basis of the normative postulates of conservation biology. I argue that the recognition of intrinsic natural value is a fundamental and non-negotiable aspect of an eco-evolutionary worldview. Recently, relational values, “preferences, principles, and virtues associated with relationships”, have been proposed as a third category of values in nature, which may help to resolve the debate between instrumental and intrinsic valuation. By depicting intrinsic values as part of an unhelpful dichotomy between anthropocentric and ecocentric values, the current assessment of relational values fails to adequately account for the modern philosophical view of intrinsic natural value. The recognition of intrinsic natural value is not merely an academic exercise, but rather a vital aspect of conservation of the biosphere; recognition of value entails the obligation to do what is right, i.e., protect the good. Any attempt to reframe the discussion about values and environmental protection through more formal recognition of relational values will need to more clearly address how relational and intrinsic values coexist and how they can jointly form the basis for nature conservation.”

Tomorrow (Tuesday), February 28, David Aldvén from the University of Gothenburg and Vattenfall AB, will give a seminar titled ”Downstream migration of anadromous brown trout”. David Aldvén finished his PhD with a thesis titled ”Migration in anadromous brown trout”. The frame of his thesis is available online here.

The seminar will be given at 13:30 in room 5F416 on Karlstad University. Everyone is welcome to attend!

Fish Passage 2017 – International Conference on Engineering and Ecohydrology for Fish Passage will be held in Corvallis, Oregon, USA on June 19-21 2017. The confererence ”…promises to be an important international forum for researchers and practitioners to exchange findings and experiences on fish passage issues.

Fish Passage 2017 will be of interest to researchers, educators, practitioners, funders, and regulators who have an interest in advancements in technical fishways, nature-like fishways, stream restoration and stabilization, dam removal, and the myriad of funding, safety, climate change, and other socio-economic related issues surrounding connectivity projects.

This is a three-day conference with concurrent sessions in engineering, biology, management and monitoring techniques. The conference will also feature plenary talks, professional networking opportunities, and a poster session. Independently offered short courses, workshops and tours will be available immediately before and/or after the conference.”

Plenary speakers will be say’ay’ – John Eli Sirois, Futoshi Nakamura, Tony Farrell, Paul T. Jacobson, and Kurt D. Fausch. Read more about the plenary speakers here. Also, pre-conference short courses and post-conference tours are available. Read more about the conference at www.fishpassageconference.com.

John Piccolo recommends the short film ”Lahontan Cutthroat Trout: A prehistoric legend returns”. The film briefly discusses the restoration of cutthroat trout to Pyramid Lake and the Truckee River in Nevada, USA. This strain of cutthroat trout was assumed extinct until remnants of the population were found in streams in neighboring Pilot Peaks. This started great efforts to re-introduce the socially and culturally important fish population to the lake. Watch the film here:

Dokumentären ”Tana älv – mellan tre länder” (”Tanaelv – den beste elva” på norska) ligger just nu uppe på SVT-play. FIlmen handlar om laxen i älven och människorna runt den. Forskare, förvaltare, husbehovsfiskare och repressentanter för turistfisket kommer till tals. Älven – och dess biflöden – är hem för en mängd lokalt anpassade laxpopulationer och fisketrycket måste minskas för att skydda hotade laxpopulationer. Detta skapar både lokala och internationella konflikter.

A postdoc position in the ecology of river restoration is open for applications at Karlstad University: ”The main duty of the position is to conduct research on the effects of dam removal and the installation of fish-friendly turbines on river connectivity and ecology. Intact river connectivity is essential for many organisms in running water, and especially so for organisms that move between different habitats to complete their life cycle, such as many migratory fish species. Many rivers are modified by dams such as hydroelectric power plants. Dams disconnect river stretches and habitats, thereby reducing dispersal and migration possibilities for fish, benthos, and plants, with negative effects on individuals, populations, and communities. The post-doctoral candidate will be expected to evaluate the effects of complete dam removal and installation of fish-friendly turbines as measures to improve connectivity in rivers.”. The deadline for applying is February 28.

Last Tuesday, Ewa Orlikowska, PhD-student at Swedish University of Agricultural Sciences, gave a seminar titled ”Gaps in ecological research on the world’s largest internationally coordinated network of protected areas: A review of Natura 2000” at Karlstad University. The seminar is available online upon request. Send an e-mail to john.piccolo@kau.se to get access to the seminar.

The papers Gaps in ecological research on the world’s largest internationally coordinated network of protected areas: A review of Natura 2000 and Contribution of social science to large scale biodiversity conservation: A review of research about the Natura 2000 network, both by Orlikowska et al. relate to the seminar content.
