“…Microscopy, HPLC pigments and molecular analysis with either chloroplast 16S rRNA or 18S rRNA each provide useful ways to identify the factors driving differences in the taxonomic composition of microbial communities among sites, sampling times or experimental treatments. It is unusual to apply all five methods in a single study, but previous studies have used pairs of methods to differentiate communities: fluorescence (pigments) and microscopy ( Lévesque et al, 2020 ); 18S rRNA/18S rRNA genes and microscopy ( Gao et al, 2018 ; Rimet et al, 2018 ; Minerovic et al, 2020 ); and chloroplast 16S rRNA and microscopy ( Eiler et al, 2013 ; Bennke et al, 2018 ). In the present study, 18S rRNA and chloroplast 16S rRNA offered better resolution for the separation of the samples among lakes and sample period than microscopy, as observed elsewhere ( Yan et al, 2007 ).…”

“…Urbanization is often associated with eutrophication, and species characteristic of urban lakes are therefore often bloomforming cyanobacteria (Napiórkowska-Krzebietke and Dunalska, 2015;Lévesque et al, 2020). Anthropogenic factors such as logging and pasture development can also select for specific phytoplankton traits (e.g., pigment composition in relation to N:P ratio and heterotrophy; Loewen et al, 2021).…”

Changes in the Community Structure of Under-Ice and Open-Water Microbiomes in Urban Lakes Exposed to Road Salts

2021

Salinization of freshwater is increasingly observed in regions where chloride de-icing salts are applied to the roads in winter, but little is known about the effects on microbial communities. In this study, we analyzed the planktonic microbiomes of four lakes that differed in degree of urbanization, eutrophication and salinization, from an oligotrophic reference lake with no surrounding roads, to a eutrophic, salinized lake receiving runoff from a highway. We tested the hypothesis that an influence of road salts would be superimposed on the effects of season and trophic status. We evaluated the microbial community structure by 16S rRNA sequencing for Bacteria, and by four methods for eukaryotes: 16S rRNA chloroplast analysis, 18S rRNA sequencing, photosynthetic pigment analysis and microscopy. Consistent with our hypothesis, chloride and total nitrogen concentrations were among the most important statistical factors explaining the differences in taxonomic composition. These factors were positively correlated with the abundance of cryptophytes, haptophytes, and cyanobacteria. Ice-cover was also a major structuring factor, with clear differences between the winter communities and those of the open-water period. Nitrifying and methane oxidizing bacteria were more abundant in winter, suggesting the importance of anaerobic sediment processes and release of reduced compounds into the ice-covered water columns. The four methods for eukaryotic analysis provided complementary information. The 18S rRNA observations were strongly influenced by the presence of ribosome-rich ciliates, but revealed a much higher degree of taxonomic richness and greater separation of lakes, seasonal changes and potential salinity effects than the other methods.

“…Dicho de otro modo, los grupos funcionales del fitoplancton (Kruk et al, 2010) han permanecido bastante constantes a largo plazo, dominando los grupos III (organismos filamentosos con aerotopos), IV (organismos de tamaño medio sin funcionalidades especiales) y V (flagelados unicelulares). En cualquier caso, el tipo de flora planctónica es similar a la encontrada en ambientes lacustres urbanos de China (Chen et al, 2020) y en el grupo-3 de ambientes estancados urbanos de la zona de Quebec, que incluye lagos y embalses de aguas permanentes en zonas residenciales (Lévesque et al, 2020).…”

El Lago de la Casa de Campo fue desecado en 2018 y desde su reinundación a comienzos del año siguiente se estudiaron la colonización del fitoplancton y los factores que condicionaban su dinámica durante un ciclo anual. En los primeros meses tras el relleno del lago, el morfotipo más frecuente fue el de los flagelados sensu lato y la riqueza de taxones resultó aproximadamente constante, pero la biomasa total se mantuvo baja. A partir de junio, las dos últimas variables aumentaron notablemente, dominando las Clorofitas Chlorococcales y las Cianofitas. Los principales factores de control físico-químico de la biomasa total pudieron ser el carbono orgánico disuelto y el nitrógeno orgánico. Los escasos datos disponibles, registrados en otros años, parecen excluir al zooplancton como factor de control. El origen principal de la colonización fitoplanctónica fue el humedal del Valchico, situado a unos 5 kilómetros aguas arriba, y verosímilmente se debió a la zoocoria por Anátidas.
