Magnus Huss
My research focuses on how individual development and body growth governs ecological dynamics in fish communities and aquatic ecosystems, and often in the context of environmental change. I work in a wide array of study systems, including lakes and the Baltic Sea. Methods include experiments, observations and mathematical modeling.

Teaching

I am leading the postgraduate course in Fish and Fisheries Ecology and the MSc course Ecology for Fish Management and Conservation

I also teach on several other courses in e.g. Applied Conservation Biology (BSc), Sustainability Ecology (BSc) and regularly on postgraduate courses on topics such as community ecology and scientific writing.

 

Research

Many of the projects I am currently working on aims to add understanding about how interacting human pressures and climate change may impact aquatic resources  by linking physiological responses to community-level impacts. 

Specific study topics include:
  -  Implications of environmental gradients for coastal food-web processes
  -  Fish community responses to rising temperatures and darker waters
  -  Aquatic food web efficiency and climate change

Supervision

PhD-students:

Viktor Thunell 2016 - (co-supervisor) Effects of warming and fishing on fish community dynamics

Jingyao Niu 2020 - (co-supervisor) warming-induced evolution in fish

Former PhD students:

Philip Jacobson 2015-2020. Predator-prey interactions, salmon population dynamics and bioaccumulation

Renee Van Dorst 2016-2020. Fish community responses to rising temperatures and darker waters

Max Lindmark 2016-2020 (co-supervisor) How trophic interactions mediate physiological responses to climate change

Ulrika Beier 2013-2016 (co-supervisor) Habitat selection and indirect interactions in fish communities

Regularly supervise MsC students, e.g. on topics such as effects of warming, browning and eutrophicaiton on fish and aquatic food webs
