<\/path><\/svg><\/span><\/path><\/svg><\/span>Comparing diatom communities between the different stream mat types of the McMurdo Dry Valleys, Antarctica (supervisor: Tyler J. Kohler)<\/span><\/div>

The McMurdo Dry Valleys of Antarctica are one of the coldest and driest places on Earth. Yet, glaciers melt here every summer during the 24-hour sunlight, creating meltwater streams that serve as an oasis for life in an otherwise barren landscape. In these streams, three major community types are present, referred to as ‘mat types’: green mats (formed by chlorophytes), black mats (formed by the cyanobacterial genus Nostoc<\/em>), and orange mats (formed by the filamentous cyanbacterial genera such as Phormidium<\/em>). All three mat types also harbor diatoms, which are unicellular algae representing some of the greatest diversity of any organismal group in Antarctica. These mat types occupy different parts of the streambed, and have different responses to varying hydrological conditions. Thus, as the climate warms, it is likely that some mat types will become more common than others, potentially favoring some diatom taxa, and creating climate change ‘winners’ and ‘losers’. Therefore, the objective of this Masters thesis will be to compare diatoms from these three different mats types, which were collected over various streams from the McMurdo Dry Valleys in the 2024-2025 summer. The project will be carried out in collaboration with investigators from our department, as well as will colleagues in the United States.<\/p><\/div><\/div>\n<\/div>\n<\/div><\/div>\n\n\n\n

<\/path><\/svg><\/span><\/path><\/svg><\/span>Stream microbial communities and the River Continuum Concept (supervisor: Tyler J. Kohler)<\/span><\/div>

The River Continuum Concept is a conceptual framework that describes how lotic ecosystem characteristics change from small headwaters to large rivers. While its predictions have been well explored in terms of physico-chemical characteristics, benthic algae, organic matter composition, and macroinvertebrate communities, much less attention has been directed towards applying this \u2018traditional\u2019 framework to microbes, despite their disproportionately high taxonomic and functional diversity in stream ecosystems. Here, I would like a student to evaluate the literature in terms of microbial diversity (both taxonomic [i.e. species] and functional [i.e. genes]) in streams, and how these current data align with predictions made by the River Continuum Concept and its derivatives, such as the Serial Discontinuity Concept, Flood-Pulse Concept, etc.).

<\/path><\/svg><\/span><\/path><\/svg><\/span>Extracellular enzymes as a tool to investigate freshwater organic matter utilization and nutrient limitation (supervisor: Tyler J. Kohler)<\/span><\/div>

Extracellular enzymes are used by microbes to acquire important elements, such as carbon, nitrogen, and phosphorus, from organic matter. Thus, understanding controls on different enzyme classes and their associated activities are important for predicting nutrient limitation, as well as processes such as organic matter decomposition and remineralization. This is timely given widespread eutrophication from nutrient loading, as well as climate change due to ongoing carbon emissions. For this thesis, I would like a student to investigate how extracellular enzymes operate in streams and lakes, summarize common field and lab methodologies for measuring their activity, explain how they can be used in water quality monitoring, and what these data can ultimately tell us about the ecosystems they are analyzed from.

Do your internship with us:<\/h3>\n\n\n\n

We have interns in our lab regularly, so feel free to contact us<\/a> in case of interest. In our lab, you may learn different light and electron microscopy techniques, microbial culturing and permanent slide preparations, molecular biology techniques (for both microbial cultures and environmental DNA), phylogenetic and community data analysis and\/or fieldwork. We usually do not have devoted funds for interns, though, so external funding to cover your living costs in Prague (e.g., via EU’s Erasmus+<\/a> programme) are usually needed. <\/p>\n\n\n\n
