It will cover algal systematics, biogeography and taxonomy; will address algal physiological and ecological aspects, and will discuss algal responses to human dimension issues such as global change, nutrient cycling, biogeochemical products and toxicity with an emphasis on marine macroalgae. Course description The course employs active learning and sometimes group strategies to increase students’ engagement. Learning will be achieved through lectures, invited speakers and different learning strategies that will provide information on biological concepts as well as methods for the study and use of algae. Objectives 1- Provide students with a basic knowledge of the evolution, taxonomy and biogeography of major algal groups. This will be achieved by critically reading scientific literature and analyzing particular cases. 2- Provide students with a good understanding of the anatomical, morphological and physiological features of major algal groups. This will be achieved through active learning exercises and linking structure and function aspects of algae. 3- Prepare students to critically analyze the role of algae in ecological processes related with global change. This will be achieved by understanding algal responses to global change analyzing study cases.

  • Mechanisms of Photoacclimation on Photosynthesis Level in Cyanobacteria
    5 Mechanisms of Photoacclimation on Photosynthesis Level in Cyanobacteria Sabina Jodłowska and Adam Latała Department of Marine Ecosystems Functioning, Institute of Oceanography, University of Gdańsk, Gdynia Poland 1. Introduction Cyanobacteria are oxygenic photoautotrophic prokaryotes, which develop in many aquatic environments, both freshwater and marine. They successfully grow in response to increasing eutrophication of water, but also because of shifts in the equilibrium of ecosystems (Stal et al., 2003). Cyanobacteria possess many unique adaptations allowing optimal growth and persistence, and the ability to out-compete algae during favorable conditions. For instance, many species are buoyant due to the possession of gas vesicles, some of them are capable of fixing N2, and unlike algae, which require carbon dioxide gas for photosynthesis, most cyanobacteria can utilize other sources of carbon, like bicarbonate, which are more plentiful in alkaline or high pH environments. The cyanobacteria live in a dynamic environment and are exposed to diurnal fluctuations of light. Planktonic species experience differences in irradiance when mixed in the water column (Staal et al., 2002), whereas mat-forming cyanobacteria are exposed to changes in light intensity caused by sediment covering or sediment dispersion. Such rapidly changing environmental factors forced photoautotrophic organisms to develop many acclimation mechanisms to minimize stress due to low and high light intensities. High irradiance may damage photosynthetic apparatus by photooxidation

Course Objectives: to survey the various organisms collectively classified as algae, on a comparative basis. Structure, reproduction and evolution will be stressed. Because many algae have economic significance, there will also be an emphasis on the uses of algae. This will emphasize the use of algae as dynamic, model organisms for experimental biology - a topic that will be experienced firsthand in laboratory. Grading and Organization: there will be two “midterm” examinations and a final examination. Although exams will be designed to be completed in much less time, a three-hour period is reserved for each, so that time constraints will not be a factor. Each exam will be worth 100 points. There are no make-up examinations. An additional 50 points will be assessed in lab, based upon the quantity and quality of participation, and on specific in-lab exercises. The final grade will be determined on the basis of the total 350 points.
