Type of course

Master course for biology students - mandatory for MSc students specializing in Freshwater Ecology and open for all MSc students in biology.

Students from freshwater and marine ecology or other Master programs at the department (AMB) will be prioritized. The admission will take place during the first lecture. First lecture is mandatory. 

The course is limited to 16 students due to the capacity of the field course.

The course is also available as a singular course.

Admission requires a Bachelor`s degree (180 ECTS) or equivalent qualification, with a major in biology of minimum 80 ECTS.

Course overlap

If you pass the examination in this course, you will get an reduction in credits (as stated below), if you previously have passed the following courses:

BIO-308 Fish ecology - ecological interactions 10 stp

Course content

The course deals with ecological interactions with special emphasize on aquatic (i.e., freshwater and marine) systems. Ecological niche, competition, predation, parasitism, and food webs are central topics, and key principles and theories in relation to these concepts and interactions are addressed. The dynamic aspects of the interactions are focused, also considering effects of species introductions and other biomanipulations and ecological impacts. Lessons include a combination of lectures presenting basic theory and seminars for discussions of relevant literature. The seminars are compulsory and based on thorough preparations from the students. A compulsory field course gives the students hands-on experience with ecological studies in subarctic lakes and intertidal rocky shores.  

The required safety training for the field course will be given as part of the teaching.
