- Abstract
Current -omics methods allow the collection of a large amount of information that helps in describing the microbial diversity in nature. Here, and as a result of a culturomic approach that rendered the collection of thousands of isolates from 5 different hypersaline sites (in Spain, USA and New Zealand), we obtained 21 strains that represent two new Salinibacter species. For these species we propose the names Salinibacter pepae sp. nov. and Salinibacter grassmerensis sp. nov. (showing average nucleotide identity (ANI) values < 95.09% and 87.08% with Sal. ruber M31T, respectively). Metabolomics revealed species-specific discriminative profiles. Sal. ruber strains were distinguished by a higher percentage of polyunsaturated fatty acids and specific N-functionalized fatty acids; and Sal. altiplanensis was distinguished by an increased number of glycosylated molecules. Based on sequence characteristics and inferred phenotype of metagenome-assembled genomes (MAGs), we describe two new members of the genus Salinibacter. These species dominated in different sites and always coexisted with Sal. ruber and Sal. pepae. Based on the MAGs from three Argentinian lakes in the Pampa region of Argentina and the MAG of the Romanian lake Fără Fund, we describe the species Salinibacter pampae sp. nov. and Salinibacter abyssi sp. nov. respectively (showing ANI values 90.94% and 91.48% with Sal. ruber M31T, respectively). Sal. grassmerensis sp. nov. name was formed according to the rules of the International Code for Nomenclature of Prokaryotes (ICNP), and Sal. pepae, Sal. pampae sp. nov. and Sal. abyssi sp. nov. are proposed following the rules of the newly published Code of Nomenclature of Prokaryotes Described from Sequence Data (SeqCode). This work constitutes an example on how classification under ICNP and SeqCode can coexist, and how the official naming a cultivated organism for which the deposit in public repositories is difficult finds an intermediate solution.

Figure S1. Geographical distribution of the six locations studied here and their inter-location distances (given in the table). The distances given in each location refer to Mallorca. The hypersaline here are: Mallorca (Es Trenc and S’Avall and separated by 3.5 km) and Santa Pola in Spain, Fără Fund in Romania, Great Salt Lake (USA), Pampa (Laguna Colorada Chica and Laguna Colorada Grande, separated by 23 Km), and Lake Grassmere (New Zealand). Table S1. Statistics of Salinibacter MAGs recovered using different bioinformatic tools. MAGs selected for further analysis and taxonomic classification are marked in red. Text S1: In addition to the taxonomic study, here we assessed the different tools SPADES and MegaHIT assemblers, and MetaBAT binning tools selecting contigs with length > 2,000 pbs or > 5,000 pbs to retrieve the best quality MAG (Sup. Table S1). We observed that different tools and combinations rendered different qualities of the MAGs. The selection of contigs with length > 5,000 pbs binning rendered MAGs with a lower genome size, lower completeness and similar contamination. From the FF metagenome (Romania), the highest quality MAG was retrieved using the assembler SPADES and MetaBAT binning tool using a minimum contig length of 2,000 pbs. From CCH and CG metagenomes (Argentina), the highest quality MAGs were retrieved using the assembler MegaHIT and MetaBAT binning tool using a minimum contig length of 2,000 pbs (Sup. Table S1).

- Abstract
The intensity and frequency of storms are projected to increase in many regions of the world because of climate change. Storms can alter environmental conditions in many ecosystems. In lakes and reservoirs, storms can reduce epilimnetic temperatures from wind‐induced mixing with colder hypolimnetic waters, direct precipitation to the lake's surface, and watershed runoff. We analyzed 18 long‐term and high‐frequency lake datasets from 11 countries to assess the magnitude of wind‐ vs. rainstorm‐induced changes in epilimnetic temperature. We found small day‐to‐day epilimnetic temperature decreases in response to strong wind and heavy rain during stratified conditions. Day‐to‐day epilimnetic temperature decreased, on average, by 0.28°C during the strongest windstorms (storm mean daily wind speed among lakes: 6.7 ± 2.7 m s−1, 1 SD) and by 0.15°C after the heaviest rainstorms (storm mean daily rainfall: 21.3 ± 9.0 mm). The largest decreases in epilimnetic temperature were observed ≥2 d after sustained strong wind or heavy rain (top 5th percentile of wind and rain events for each lake) in shallow and medium‐depth lakes. The smallest decreases occurred in deep lakes. Epilimnetic temperature change from windstorms, but not rainstorms, was negatively correlated with maximum lake depth. However, even the largest storm‐induced mean epilimnetic temperature decreases were typically <2°C. Day‐to‐day temperature change, in the absence of storms, often exceeded storm‐induced temperature changes. Because storm‐induced temperature changes to lake surface waters were minimal, changes in other limnological variables (e.g., nutrient concentrations or light) from storms may have larger impacts on biological communities than temperature changes.

- Abstract
In many regions across the globe, extreme weather events such as storms have increased in frequency, intensity, and duration due to climate change. Ecological theory predicts that such extreme events should have large impacts on ecosystem structure and function. High winds and precipitation associated with storms can affect lakes via short‐term runoff events from watersheds and physical mixing of the water column. In addition, lakes connected to rivers and streams will also experience flushing due to high flow rates. Although we have a well‐developed understanding of how wind and precipitation events can alter lake physical processes and some aspects of biogeochemical cycling, our mechanistic understanding of the emergent responses of phytoplankton communities is poor. Here we provide a comprehensive synthesis that identifies how storms interact with lake and watershed attributes and their antecedent conditions to generate changes in lake physical and chemical environments. Such changes can restructure phytoplankton communities and their dynamics, as well as result in altered ecological function (e.g., carbon, nutrient and energy cycling) in the short‐ and long‐term. We summarize the current understanding of storm‐induced phytoplankton dynamics, identify knowledge gaps with a systematic review of the literature, and suggest future research directions across a gradient of lake types and environmental conditions.

La laguna Chascomús es un típico lago somero, eutrófico y turbio de la Pampa Deprimida. Se encuentra permanentemente mezclada y presenta un grado elevado de homogeneidad espacial. La alternancia entre períodos de déficit y de exceso de agua, característica de la región, determina que la laguna sufra ciclos periódicos de sequía e inundación. Las primeras crónicas indican que a principios del siglo XX la laguna era turbia y que las primeras matas de vegetación habrían aparecido después de las inundaciones de 1913 y 1914. Hacia mediados del siglo XX, Chascomús se encontraba en un estado de aguas claras y colonizada de manera profusa por macrófitas. En ese momento, aproximadamente 60% de la biomasa de peces correspondía al pejerrey (Odontesthes bonariensis). En las últimas décadas, esta condición se modificó y en la actualidad la laguna está estabilizada en un estado turbio en el que la producción primaria fitoplanctónica es muy alta y se encuentra limitada por luz. La biomasa de fitoplancton representa el 75% del carbono de la columna de agua y predominan las cianobacterias nanoplanctónicas. Estudios de campo y experimentos en mesocosmos indican que la transparencia del agua está controlada por la cantidad de radiación incidente a través de una retroalimentación negativa con la producción primaria. La biomasa fitoplanctónica elevada se mantiene debido a la ausencia de un control efectivo por parte del zooplancton herbívoro. Como resultado de la presión de depredación que ejerce la comunidad actual de peces, la composición del zooplancton no presenta filtradores eficientes (e.g., Daphnia y otros cladóceros de gran tamaño). En la actualidad el pejerrey representa un porcentaje muy bajo de la biomasa total de peces (0.04%), mientras que los micrófagos omnívoros, como el sabalito (Cyphocharax voga), son dominantes. La dominancia del sabalito no sólo explicaría la baja abundancia del zooplancton, sino que al mismo tiempo contribuiría a evitar o retardar la consolidación del material sedimentado. Laguna Chascomús is an eutrophic, turbid, shallow lake typical of the Flooding Pampa region of Argentina. This shallow lake is permanently mixed and displays a high degree of spatial homogeneity. The cyclical periods of excess and shortage of rain, characteristic of this area, result in periodic drying and flooding events. According to newspaper articles published during the first half of the XX century, the lake was originally turbid. The first patches of rooted vegetation appeared after the 1913 y 1914 floods. During most part of the XX century the lake remained in a “clear”, vegetated state. During this period the dominant fish species was the silverside (pejerrey), Odontesthes bonariensis, which accounted for over 60% of the total fish catches (in biomass). Instead, by the end of the latest century the lake shifted to a turbid state that persisted until present. Currently, the phytoplankton primary production is limited by light and its values are among the highest ones reported for natural aquatic systems. In light limited systems, the transparency may be expected to be controlled by the amount of incident light, through a negative feedback loop with primary production. These predictions have been confirmed, both in mesocosm experiments and “in situ”. The phytoplankton biomass, dominated by nanoplanktonic cyanobacteria accounts for 75% of the total amount of carbon in the water column. The equilibrium predicted by the light limitation theory could not hold if the model assumptions were violated. This situation could happen if the phytoplankton biomass were controlled by herbivore zooplankton. However, such a control of primary producer by herbivores seems to be precluded due to the absence of large-sized zooplankton grazers, presumably due to the composition of the fish assemblage. In contrast to earlier reports of the 1960, the proportion of pejerrey biomass is presently quite low (0.04%), while presently the community is dominated by omnivore microphagous, such as the sabalito (Cyphocharax voga). The dominance of sabalito could not only explain the composition of the zooplankton community, but it also could contribute to prevent or delay the consolidation of sediments.
