Table A3.
Mean water temperature (°C) and light intensity (Lx) during diel intervals under various field and laboratory conditions between 2016–2018. Data are displayed for each day of experiment separately. Cercarial emergence during the longest parts of the natural photoperiod in summer (day interval in August) and autumn (night interval in October) are divided into half and termed as Day 1, Day 2 and Night 1, Night 2. Data marked in yellow represent additional data illustrating/simulating natural thermo- and photo-conditions in the field or a climatic chamber (note that cercarial emergence was not investigated according to these temperature and light conditions; see Materials and Methods for experimental conditions).
