T\u00e4ss\u00e4 pro gradu -tutkielmassa selvitettiin, miten l\u00e4mpeneminen ja rehev\u00f6ityminen vaikuttavat kasviplanktonin kuuden eri p\u00e4\u00e4ryhm\u00e4n kasvunopeuksiin. Jokaisesta ryhm\u00e4st\u00e4 valittiin 1\u20132 lajia, joiden kasvua seurattiin nelj\u00e4ss\u00e4 erilaisessa k\u00e4sittelyss\u00e4. L\u00e4mpenemisen vaikutusta kasvuun selvitettiin kahden eri l\u00e4mp\u00f6tilan (18 ja 23 \u00baC), ja rehev\u00f6itymisen kahden eri fosfaattipitoisuuden (20 ja 80 \u03bcg/l) avulla.

As a result of climate change and human activities, surface water temperatures have risen, and there have been changes in nutrient availability. The purpose of this master\u2019s thesis was to investigate how warming and eutrophication affect the growth rates of six different main groups of phytoplankton. From each group, 1\u20132 species were selected, the growth of which was monitored in four different treatments. The effect of warming on growth was tested by using two different temperatures (18 and 23 \u00baC), and eutrophication with two different phosphate concentrations (20 and 80 \u03bcg/l). Contrary to the hypotheses, temperature and phosphate concentration did not affect the growth rates of all the species used in the work. In addition, cyanobacteria did not benefit most from higher temperature, nor did r-strategists from higher phosphate, as hypothesized. It could be concluded that algae rich in nutritional value could be better competitors than expected as the surface water temperatures rise, and eutrophication occurs. This thesis provided species-specific information on the response of phytoplankton to temperature and phosphate concentration. Based on the thesis, the phosphate content of water bodies in particular will determine the structure of phytoplankton communities and which phytoplankton species will become more common. As the climate continues to warm, it is especially important to pay attention to the nutrient content of water bodies.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2022-12-20T05:43:52Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2022-12-20T05:43:52Z (GMT).
