The paper presents the germination of different types of gyrogonites of Chara intermedia A. Braun 1836. The study material was collected from the surface layer of sediments (sediment gyrogonites) and from dead C. intermedia specimens inhabiting a post-excavation pit. As a result of a low level of water and seasonal drying, two morphological types of gyrogonites taken from the thallus were distinguished: fully ripe gyrogonites and gyrogonites in oosporangium remains. The highest germination rate was recorded for the sediment gyrogonites. At the end of the experiment, about 28% of germinating gyrogonites originating from sediments were observed. The value of this parameter was over 3-fold higher than that of fully ripe gyrogonites produced by the thallus and more than 5-fold higher in relation to gyrogonites in the oosporangium remains. The results of this experiment indicate that the germination of the two morphological types of gyrogonites taken from plants depends on the degree of their maturity and can take place under limited light conditions. Drying of charophyte thallus in shallow water bodies may have a significant impact on the degree of maturity of gyrogonites, their morphological differentiation, and sediment seed bank characteristics.

“…The majority of stands with Chara vulgaris and C. globularis in streams of Central Europe were identified by good water transparency and richness in calcium with high conductivity and pH (Bornette & Arens 2002, Velasco et al 2003, Blaženčić 2014, Caisová & Gąbka 2009, Urbaniak et al 2011. These species are relatively common on heterogeneous substrates dominated by gravel and sand habitats found in shallow parts of streams (0.5 m depth).…”

“…This species is a very useful indicator in shallow or very shallow habitats and mesotrophic rivers, but it is not often observed in lakes (Gąbka 2009). In standing waters and in mires, the presence of C. vulgaris and C. globularis is related to fertile habitats, particularly those rich in calcium (Gąbka 2009, Urbaniak et al 2011, Langangen 2013, Blaženčić 2014. Indeed, at shallow sites, C. vulgaris tolerates a high trophic status of water and elevated salinity (Gąbka 2009).…”

I n t e r n a t i o n a l J o u r n a l o f O c e a n o g r a p h y a n d H y d r o b i o l o g y AbstractThe study focused on the relationships between charophytes and the surrounding species composition and environmental factors in a lowland stream (Flinta stream, Western Poland). A total of 32 vegetation plots (4 m × 4 m) and 13 environmental variables were tested. Detrended correspondence analysis (DCA) and canonical correspondence analysis (CCA) were used to describe the relationships between the species composition and the selected variables. Dominance curves of aquatic plants, response curves (GAMs model) of charophytes and other macrophytes to the velocity gradient (the most important environmental factor, the Monte Carlo test) were prepared. In this study, 2 species of charophytes were recorded: Chara vulgaris and Chara globularis and 5 other co-occurring macroscopic algae, 2 mosses and 10 vascular plants. In the studied stream, charophytes occupied the separate niche. Chara vulgaris stands with moss vegetation were found in stream sections with the highest velocity of the water current (0.29 m s -1 mean), and the Chara globularis (with dominantPotamogeton species), preferred sections with the smallest water current velocity (0.19 m s -1 mean).Charophytes seem to respond to ecological gradients differently from mosses and vascular plants. These differences are related to current velocity, pH, conductivity and organic matter in bottom sediments, and to the niche differentiation associated with them.
