“…Diesing in freshwaters has been increased during the last three decades and currently the species is claimed to be common phytoplankton dominant in many brown-coloured lakes (Cronberg et al, 1988;Lepisto¨et al, 1994;Wille´n, 2003;Laugaste and No˜ges, 2005). The species blooms were sometimes followed by the reports on skin problems in people who had bathed in such lakes (Cronberg et al, 1988;Hongve et al, 1988;Lepisto¨et al, 1994).…”

“…It was suggested that an intensive development of the alga is an effect of the acidification (Cronberg et al, 1988;Hansson, 1996), the increased phosphorus and ammonium loading (Lepisto¨and Saura, 1998;Hehmann et al, 2001), the increased dissolved organic carbon or fulvic acid concentrations (Findlay et al, 2005;Rengefors et al, 2008) and the extension of the growing season due to the global warming .…”

-Using data from nine lakes, sampled between 2002 and 2010, as well as literature we have analysed blooms of Gonyostomum semen (Ehr.) Diesing in a new spreading area (Polesie region, Central-Eastern Poland). We tried to determine habitat suitability for high biomass of the species, including both physicochemical and morphometric features. High biomass of Gonyostomum ( > 1.4 mg.L x1 ) was found in three groups of coloured water bodies: (a) very small ( < 0.002 km 2 ) peat pits with low pH values and mineral content; (b) larger ponds with neutral pH values and intermediate conductivity; (c) natural lakes with intermediate parameters in terms of area, pH and mineral content. There were no statistical differences regarding the values of the species biomass among the groups of lakes. Gonyostomum biomass was closely positively correlated with water colour, whereas it was weakly negatively correlated with lake area and depth. The results show that G. semen in a new spreading area bloomed in a broad spectrum of freshwater habitats.

“…3). Thus, Gonyostomum semen, dominant in Comprida Lagoon during Period I, can be recognized as a representative species of group Q, which is common in humic lakes of high latitudes (Cronberg et al 1988), usually having low calcium contents and acidic waters . This species was also found forming bloom in a shallow, humic artificial pond in a Brazilian tropical region (M. Menezes, unpublished data).…”

RESUMO -(Composição e grupos funcionais do fitoplâncton de uma lagoa costeira tropical húmica, Brasil). Este trabalho apresenta a composição e os grupos funcionais do fitoplâncton da lagoa Comprida, uma lagoa costeira tropical húmica localizada no sudeste brasileiro. Foi registrado um total de 28 táxons distribuídos em oito divisões taxonômicas: 26% Heterokontophyta, 21% Chlorophyta, 21% Cyanophyta, 14% Bacillariophyta, 14% Cryptophyta e 4% Prymnesiophyta. Vinte e três táxons foram identificados em nível específico e intraespecíficos, dos quais quatro constituem novos registros para o Brasil e dois para o estado do Rio de Janeiro. O fitoplâncton da lagoa Comprida esteve constituído por alguns flagelados, mas também por organismos picoplanctônicos eucariontes e procariontes, cianobactérias filamentosas e algumas diatomáceas. A biomassa foi menor que a comumente encontrada em outros sistemas lacustres e mostrou uma notável variabilidade temporal. Em relação aos grupos funcionais, as populações foram agrupadas em oito grupos: Q, Z, E, N, X 3 , X 2 , S 1 e Y, muitos dos quais típicos de sistemas oligo ou mesotróficos, tolerantes a baixas concentrações de nutrientes e sensíveis a baixos valores de pH.Palavras-chave: fitoplâncton, trópicos, sistemas húmicos, lagoas costeiras, grupos funcionais, sudeste do Brasil ABSTRACT -(Phytoplankton composition and functional groups in a tropical humic coastal lagoon, Brazil). This paper presents the composition and functional groups of the phytoplankton from Comprida lagoon, a tropical humic coastal Lagoon located in Southeast Brazil. A total of 28 taxa was found, distributed in eight taxonomic divisions as follows: 26% Heterokontophyta, 21% Chlorophyta, 21% Cyanophyta, 14% Bacillariophyta, 14% Cryptophyta, and 4% Prymnesiophyta. Twenty-three taxa were identified at the specific and infraspecific levels, from which four are new records for Brazil and two for Rio de Janeiro State. Phytoplankton of the Comprida lagoon was comprised of several flagellates, but also eukaryote and prokaryote picoplankton, filamentous cyanobacteria and several diatoms. The biomass was lower than that found in other lacustrine systems, and showed remarkable temporal variability. According to the functional-group approach, the populations formed eight groups: Q, Z, E, N, X 3 , X 2 , S 1 and Y, most typical of oligo-or mesotrophic systems, tolerant to nutrient deficiency and sensitive to increased pH.

“…Diesing is a bloomforming flagellate species that often occurs in humic lakes across Europe. During the last three decades, the number of reports on blooms of this alga in European freshwaters has increased (Cronberg et al, 1988;Lepistö et al, 1994;Noges & Laugaste, 2002;Willen, 2003;Rengefors et al, 2012;Pęczuła, 2013;Karosiene et al, 2014). The factors enabling the expansion and blooming of Gonyostomum semen are still under discussion.…”

“…The factors enabling the expansion and blooming of Gonyostomum semen are still under discussion. Among the hypothesized drivers for the observed increased distribution and abundance are eutrophication (Eloranta & Palomäki, 1986;Hongve et al, 1988;Laugaste, 1992;Lepistö & Saura, 1998), acidification (Cronberg et al, 1988;Korneva, 2000;Hansson, 2000), calcification of acid lakes (Hutorowicz, 1993), increased dissolved organic carbon (DOC), and fulvic acid concentrations (Findlay et al, 2005;Rengefors et al, 2008), as well as the extension of the growing season related to the climate change (Rengefors et al, 2012), and the alternations in planktonic food webs (consisting of a fall in the abundance of filter-feeding Cladocera) (Hansson, 2000;Hehmann et al, 2001).…”

The influence of glucose and peat extract additions on the spring recruitment of Gonyostomum semen from the sediments

2014

The effect of two various forms of DOC on the Gonyostomum semen recruitment from sediments was conducted under experimental laboratory conditions. We tested the hypothesis that DOC is a factor enhancing spring recruitment of the species by exposing sediments from a humic lake with a 17-year bloom history, to three various DOC additions (two solutions of glucose and one solution of a peat extract). Sediments and lake water were incubated for 14 days at 16°C, in 14:10 h light:dark cycle, with germling and adult cell abundance ascertained in the water every third day, and water parameters every seventh day. Our important findings were that (1) Gonyostomum recruitment was uneven and the period of germination was relatively short; (2) all treatments significantly affected germling occurrence; however, sugar-derived DOC seemed to suppress the recruitment, whereas peat extract improved it. Due to the additional phosphorus load in peat treatment (against phosphorus-free sugar treatments), it is likely that it played a major role in the observed differences, however, our results did not exclude the potential role of peatderived DOC forms. In conclusion, we proposed that Gonyostomum expansion is supported by enhanced recruitment from sediment seed banks related to water chemistry alterations, driven by the climate change.
