Karlstad University has an opening for a PhD position in aquatic conservation biology. The project will focus on “Resolving production bottlenecks for the European eel”. Conserving biodiversity is one of the major challenges in applied aquatic ecology. The European eel functions as a flagship species in marine and freshwater conservation, and its population collapse is of major concern for ecologists, fishers and managers.
The aim of the PhD project is to identify:
(i) relationships between yellow eel habitat use, growth, behavior and survival.
(ii) effects of habitat characteristics and the surrounding landscape on eel large-scale movements within freshwater systems.
(iii) functioning downstream passage solutions at hydropower plants for a wide range of silver eel phenotypes.
The position is full-time for four years. Doctoral students may also be assigned departmental duties, such as teaching, which will extend the period of employment accordingly.
Last day to apply is 5 June 2019.
A PhD position in biology (community and food web ecology) is now open for application at Karlstad University. The project will focus on evaluating the ability of forested buffer strips to maintain cross boundaries fluxes between streams and riparian ecosystems.
The aim of the PhD project is to (i) analyse the link between riparian forest buffer width and functional diversity of riparian predator communities, (ii) define optimal buffer zones for conservation of riparian ecosystem functions, based on food web complexity and ecological niches (using stable isotopes) and (iii) use DNA-barcoding to study variation in prey preference with varying buffer width and test stable isotopes as a tool to assess riparian ecosystem functions in forestry affected landscapes.
The position is full time for four years but may be extended if department duties such as teaching (maximum 20 % of a full-time position) are included.
Last application date is 14 March 2019.
Two PhD positions (1: vegetation ecology, 2: ecosystem function/host-parasite interactions) are now open for applicants at Karlstad University. Both positions are full time for five years within the River Ecology and Management (NRRV) research group and include 80 % research and 20 % department duties (mainly teaching).
The applications for both positions close on 31 January 2019.
PhD position in vegetation ecology
The project will study which factors control diaspore dispersal and plant community composition along boreal streams, which in turn may have cascading effects on functional plant diversity and ecosystem functioning. The specific research questions to be addressed will be decided in consultation with the candidate. Areas of particular interest are (1) the effects of local and landscape-scale factors for plant species composition and diversity and cascading effects on ecosystem functioning and (2) studies of factors promoting or constraining plant dispersal along streams.
Ecosystem function/host-parasite interactions
The position will focus on either the role of mussels for ecosystem function or host-parasite interactions. Areas of interest are (1) the role of mussels for stream ecosystem function and (2) host-parasite interactions between mussels and their host fish. The specific research questions to be addressed will be decided in consultation with the candidate.

A position as “Associate senior lecturer in biology with research focus on stream habitat modelling and environmental flows” at Karlstad University is now open for application. The position is a fixed-term full-time employment for four years.
“For the first three years the position will be approximately 80% research and 20% teaching. Teaching will include courses in the undergraduate and master programs in Biology. The main duty of the position is to conduct research on the effects of habitat degradation, restoration, and streamflow on stream fish populations with a focus on regulated rivers. The successful candidate will be expected to evaluate the effects of habitat and stream flow on fish distribution, growth and abundance employing advanced ecological modelling. The candidate will be the main researcher in the new project: “Advanced ecological modelling for prioritizing environmental flows and habitat restoration in regulated rivers”. The project is a collaboration between Karlstad University and key actors in river restoration including world-leading modeling consultants DHI Sweden AB, and hydropower companies Vattenfall AB Fortum AB, and Sydkraft AB.”

Hydropower dams block migration routes and disrupt longitudinal connectivity in rivers, thereby posing a threat to migratory fish species. Various fish passage solutions have been implemented to improve connectivity with varying success. For downstream migrating fish, low sloping turbine intake racks are used to guide fish to bypasses. Current knowledge, however, is based on hydropower plants with intake capacities <72 cm. There is also a trade-off between electricity generation and fish guidance (smaller bar spacing – better for fish, larger bar spacing – better for hydropower). Currently, gap widths/bar spacings of 10-20 mm are recommended but behavioral guidance effects open up the possibility of larger bar spacings.
During spring, Karlstad University in collaboration with Vattenfall and NINA, will experimentally study the behavior and passage performance of downstream migrating salmon smolts approaching a variety of low sloping intake racks. The experiments will be conducted in a new large experimental flume – Kungsrännan – at the Vattenfall hydraulic laboratory in Älvkarleby, Sweden. We will study the passage behavior and performance of smolts for alpha racks – inclined from the bottom up – and beta racks – angled from one side of the channel to the other – with different gap-widths (15-30 mm).
For this, we are looking for one interested and ambitious assistant to join us in Älvkarleby. The assistant will be salaried and is needed from mid-April to mid-June. Housing in the area can be provided. Are you interested in joining us? Contact Olle Calles for more information.
NRRV is looking for a part-time project assistant to work with the endangered thick-shelled river mussel (Unio crassus).
