La presencia de esporas de helechos asociada a la aparicion del alga Gloeotrichia, asi como a la del indeterminado 'Leiospherae', tambien relacionado con el mundo algal, nos indica que existirian unas condiciones de humedad mas o menos constantes o incluso que se producirian encharcamientos puntuales en la cavidad.
The most conspicuous forms, visible with the naked eye, were Gloeotrichia echinulata (J.
Besides the whole lake measurements, its individual basins were also analysed, particularly since Gloeotrichia and Anabaena preferred the northern eutrophic part, L.
It should be noted that the genus Gloeotrichia consisted of only one planktonic species in the lake (G.
Microcystis, TP, and Fe formed a quite close group; Aphanizomenon, residual algae (others), and TN the other somewhat diffusive group, where Anabaena was linked with temperature and Gloeotrichia with water level and with temperatures over 22[degrees]C.
According to the data for 15 years, the main cyanobacterial genera appeared in the open water on the following days of the year: Anabaena 167th day (mid-June), Microcystis 176th day, Aphanizomenon 177th day, and Gloeotrichia 180th day (end of June).
Gloeotrichia echinulata is common in well-mixed mesotrophic and eutrophic lakes found at temperate latitudes (Karlsson-Elfgren et al.
2008), Anabaena and Aphanizomenon appear in plankton in late May-early June, Gloeotrichia from middle June to late July, Microcystis in late July, peaking in August in different lakes of middle latitudes.
the summer peak is comprised of cyanobacteria (alternately the genera Gloeotrichia, Anabaena, Aphanizomenon, and Microcystis).
