Course objectives: Course provides a comprehensive overview of classical and contemporary aspects of freshwater algae biology and ecology and takes full advantage of excellent range of aquatic habitats to provide a sound introduction to their recognition, identification and ecology. Emphasis will be placed on the use of the microscope and taxonomic keys for the identification to generic and species level and their ecological importance. The course focuses on how to get grip with identification, and the broader aspects of algal morphology, structure, reproduction, and classification. The aim of the course is to provide a broad training in identification and ecology of all freshwater algal groups, with the emphasis on more common algae and those used for monitoring. Related topics, such as practical techniques, aspects of monitoring and implications of the EC Water Framework Directive, will be introduced into the course. This course will also address the needs of aquaculturists, fishery biologists, research students, conservationists, contract agency staff and others with an interest in identifying freshwater and terrestrial algae. Our combined expertise ensures that we are able to comprehensively cover all the ecologically most important algal groups.
Enrolment requirements and required entry competences for the course: Basic knowledge of algae and the basics of ecology. Autonomy in the use of computer programs: word processing (Word), tabular and graphical processing of numerical data (Excel), an image presentation (PowerPoint), and a system of e-learning.
Learning outcomes:
at the level of the study programme to which the course contributes: After completing the study program, students will have highly specialized theoretical and practical knowledge that forms the basis for originality in developing and or applying ideas. Shows a critical awareness of the diagnosis of problems based on research, bringing together knowledge from new or interdisciplinary fields. Develop new skills in response to new knowledge and techniques. Demonstrates leadership and innovation in work and study contexts that are unfamiliar, complex and unpredictable and that require solving problems involving many interacting factors. Critically reflects on the strategic work of the team. Show independence in the direction of learning and a high level of understanding of the learning process. Arguments to communicate project results and methods of professional and general audiences using appropriate techniques
at the level of the course: Apply the acquired knowledge: 1 the distribution of abiotic and biotic factors in shallow and deep lakes, 2 methods of field research and laboratory work with plankton, 3 process results in the appropriate computer programs, 4 analyze and explain the results of research and experiment to assess the degree of trophic state or saprobity aquatic ecosystems, the seasonal dynamics of plankton and its role in aquatic ecosystems food chains, 5 present and explain the results of analysis and research, 6 work collaboratively in the research, analysis and presentation of results, 6 restoration aquatic ecosystems
Course content broken down in detail by weekly class schedule (syllabus):
Course provides a broad training in identification and ecology of all freshwater algal groups, with the emphasis on more common algae used for monitoring in water quality as well as BQE (Biological Quality Element) for the EUWFD (Water Framework Directive).
