Peatland Ecology Working Group

Peatland Ecology Working Group

We are an informal working group concerned with peatland ecology. We combine expertise in plant ecology/ecophysiology and soil biology in our research topics, allowing us to combine different approaches to gain a comprehensive understanding of peatland ecosystem functioning. The group brings together not only some members of the Department of Ecosystem Biology and the Department of Experimental Plant Biology, but also people from other institutions.

One of the directions of our research is to evaluate the impact of long-term drainage and revegetation on the functioning of different peatland types (bogs, fens, spruce mires) with a focus on vegetation, organic matter quality, nutrient transformations, microbial community composition, production and emissions of greenhouse gases. Monitoring the impact of hydrological revitalization on the restoration of basic ecosystem functions of peatlands aims to identify suitable ecological indicators to evaluate the revitalization success.

Another topic is how plants have adapted to the specific environment of peatlands and how they influence peatland development. Our focus is on Sphagnum, i.e. moss ecosystem engineers, which often have a determining influence on the process of peat deposition. Therefore, in addition to the ecology and physiology of peatland plants, we also focus on the biochemical properties of their dead biomass from which peat is formed.

We also focus on interactions in the soil–plant–atmosphere continuum in ecosystems with organic soils. We study plant biomass and nutrient allocation patterns, and the quantity and quality of plant inputs (litter, root exudates) to the soil. We thus link above- and belowground plant processes to understand how changing environmental and management conditions may impact the processes and functioning of these ecosystems.

We are involved mainly in research of peatlands in the Bohemian Forest mts., in cooperation with the Šumava National Park, but also with other institutions. Within the framework of international cooperation we have participated in research of peatlands in various European countries. Selected long-term monitored sites in Šumava are also part of the Global Peatland Microbiome Project.

  • Applicants whose score in the entrance examination tests will be less than 70 % but greater than or equal to 50 %, ranked according to the percentage score achieved in the entrance examination; if the entrance examination consists of more than one test, the arithmetic average of the percentages is used.

 

  1. Applicants with special needs

An applicant with special needs (with a disability, chronic illness, or other health problems) has the right to use the support measures and services provided by the university during the entrance examination and, if accepted, also during their study. If they wish to assert this claim, they must select the option YES in the column “Consideration of special needs” in the online application form. After fulfilling all the administrative requirements associated with the application for study they will be contacted by the staff of the Support Centre for Students with Special Needs and acquainted with the next steps. More detailed information can be obtained on the centre's website (www.centrumssp.jcu.cz), by email (This email address is being protected from spambots. You need JavaScript enabled to view it.) or by telephone (00420 389 036 026). It is also possible to consult with the staff of the centre about the suitability of choice of a study programme before submitting an application for study.

Account No.: 104725778 / 0300
Identifier used for domestic payments (“Variabilní symbol”): 6020106

  1. Decision of admission/ non-admission

A written decision of admission or non-admission will be sent to every candidate immediately after an evaluation of the overall order of the candidates has been made (late June – early July). If the candidate does not agree with a decision of non-admission for study, they have the right to request that the Dean review the decision, this request is to be submitted to the Dean within 30 days of the decision being delivered. If the Dean refrains from changing the decision, the request is to be passed on for review by the Rector of the University of South Bohemia in České Budějovice. The decision of the Rector is final. A request for a review of the decision may only be justified by a statement that there was an incorrect evaluation of the fulfilment of the conditions detailed in Paragraphs 3 and 4. In all other cases, the request for review is considered as unjustified. In order to attain the necessary material for their argument, the candidate has the right to examine the documentation used by the Dean in making the decision. The candidate, however, does not have the right to examine the documentation of the other candidates or the records of the panel.

 

  1. Final provisions

The Czech language version of this Decision is binding for the admission procedure.

These conditions for admission to study on the Bachelor’s study programme of Biological Chemistry at FSci USB were approved by the Academic Senate of FSci USB on 25 November 2023.

The Laboratory of Analytical and Environmental Chemistry

In our laboratories, we mainly deal with the analysis of various samples using liquid and gas chromatography or atomic absorption spectrometry. We analyse water samples, soil, cigarette butts, plant materials, extracts from animal faeces, as well as selected substances in blood, serum and urine samples. In toxicity studies, we cooperate with the Department of Ecosystem Biology of our faculty and with the Department of Zoology, Fisheries, Hydrobiology and Apiculture of the Mendel University in Brno (Czech Rep.).

Besides developing and implementing the analytical methods, we are interested in environmentally oriented research in two directions:

  • the environmental fate of substances e.g. from cigarettes butts;
  • photodegradation of widely prescribed drugs under light conditions relevant to natural surface waters and toxicity tests of the photoproduct mixtures.

Our analytical laboratory is equipped with LC-UV/FLD/ECD instrument, LC-MS (linear ion trap) instrument, GC-FID/ECD (electron capture detector), and GC-MS instrument with triple quadrupole and flame atomic absorption spectrometer.  An UHPLC-Q-TOF instrument is planned to be purchased at the beginning of 2024. In the course of preparing samples for analysis, various techniques are used, of note the possibility of using ASE (Accelerated Solvent Extraction) should be mentioned. Irradiation of samples in photochemical studies is performed in the photochemical reactor Rayonet R100.

Over the last few years, we have introduced and validated various analytical methods. The details about individual analysed substances and methods are summarised in the Table.
