La grande majorité des indices biotiques utilisant les diatomées sont basés sur la sensibilité à la pollution des espèces. Cela constitue un frein à leur utilisation car l’identification taxonomique au niveau de l’espèce est complexe, longue, coûteuse et source d’erreurs. Afin de rendre le processus d’identification plus simple, des indices biotiques basés sur des niveaux taxonomiques supérieurs à l’espèce, comme le genre, ont été mis au point. Mais la perte d’informations associée à la réduction de la résolution taxonomique est susceptible de rendre ces outils moins efficaces. Une approche alternative et plus récente propose de baser la simplification, non pas sur la taxonomie, mais sur la phylogénie. Cette approche fait implicitement l’hypothèse qu’il existe un signal phylogénétique dans les préférences écologiques des espèces, c’est à dire que deux espèces phylogénétiquement proches sont davantage susceptibles de présenter des réponses écologiques similaires que deux espèces prises au hasard. Si un tel signal existe, il implique une possible redondance phylogénétique dans les outils de bioindication existants, en particulier ceux basés sur les niveaux taxonomiques les plus fins. L’objectif est de mettre à profit ce signal pour simplifier l’évaluation écologique des milieux aquatiques. Ce travail s’attache à développer cette approche chez les diatomées et se décompose en trois parties. Nous présentons d’abord un nouveau package R entièrement dédié à l’analyse du signal phylogénétique et à l’étude de la distribution des valeurs de traits dans les phylogénies. Nous démontrons ensuite la présence d’un signal phylogénétique pour de ii Résumé nombreux traits écologiques chez les diatomées d’eau douce. Ces traits sont les optimums écologiques de 127 espèces pour un ensemble de paramètres physico-chimiques, mesurés pendant huit ans dans des cours d’eau de l’est de la France. Nous montrons que le signal est variable en fonction des traits mais que la niche écologique des espèces étudiées est, de manière générale, dépendante de la phylogénie. Dans une troisième partie, nous pro- posons une méthode pour extraire des clusters d’espèces partageant des traits similaires tout en étant phylogénétiquement proches. Nous mettons en œuvre cette méthode sur des données de sensibilités aux pollutions pour démontrer les possibilités de simplifica- tion des indices biotiques basés sur les diatomées en prenant en compte la redondance phylogénétique. Nos résultats tendent à montrer que le potentiel de simplification en utilisant la phylogénie comme guide est significatif. Summary Diatoms are micro-algae commonly used to assess the ecological quality of freshwa- ters. Most of the biological indices using diatoms are based on species sensitivity to pollutions. This constitutes an obstacle to the use of diatoms in ecological assessment because taxonomical identification at species level is difficult, time consuming, costly and source of errors. To avoid this problem, scientists developed biological indices based on higher taxonomical levels like the genus. However, the loss of information caused by the taxonomical resolution decrease can make these methods less efficient. A more recent alternative proposes to use the phylogeny to simplify ecological assess- ment methods. This approach makes the implicit hypothesis that there is a phylogenetic signal for species ecological preferences, i.e. that closely related species are more likely to share similar ecological preferences than species taken randomly. If such a signal exists, it may mean that there is a phylogenetic redundancy in bioassessment tools, especially the ones which are based at species level. The aim is to exploit this signal to simplify the biological assessment of aquatic ecosystems. This work aims to develop this approach with diatoms and is divided in three parts. First, we introduce a new R package dedicated to the analysis of the phylogenetic signal and to study traits values patterns in phylogenies. In a second part, we demonstrate the presence of phylogenetic signal for many ecological traits in freshwater diatoms. These traits are the ecological optima of 127 species for a set of physical and chemical parame- ters. They were estimated from data collected during 8 years in rivers in eastern France. We show that the strength of the signal varied significantly from one trait to another but, iv Summary overall, diatoms ecological niches are related to the phylogeny. Finally, in a third part, we introduce a new method to extract clusters of species sharing similar traits and being phylogenetically related. We apply this method on pollutions sensitivities data in order to demonstrate the possibility to simplify biological indices based on diatoms by taking account of phylogenetic redundancy. Our results suggest that phylogenetic approaches offer a scope for simplification without an important loss of ecological information.

Insights into global planktonic diatom diversity: Comparisons between phylogenetically meaningful units that account for time Teofil Nakov, Jeremy M. Beaulieu, and Andrew J. Alverson Department of Biological Sciences University of Arkansas 1 University of Arkansas, SCEN 601 Fayetteville, AR 72701 Abstract Metabarcoding has offered unprecedented insights into microbial diversity. In many studies, short DNA sequences are binned into consecutively higher Linnaean ranks, and ranked groups (e.g., genera) are the units of biodiver- sity analyses. These analyses assume that Linnaean ranks are biologically meaningful and that identically ranked groups are comparable. We used a meta-barcode dataset for marine planktonic diatoms to illustrate the limits of this approach. We found that the 20 most abundant marine planktonic diatom genera ranged in age from 4 to 134 million years, indicating the non- equivalence of genera because some had more time to diversify than others. Still, species richness was only weakly correlated with genus age, highlighting variation in rates of speciation and/or extinction. Taxonomic classifications often do not reflect phylogeny, so genus-level analyses can include phylogenet- ically nested genera, further confounding rank-based analyses. These results underscore the indispensable role of phylogeny in understanding patterns of microbial diversity.

The associated heterotrophic or autotrophic bacteria play vital roles in regulating algal growth, production, and physiology. In this study, we investigated the detailed bacterial community structure associated with the growth of S. dohrnii’s using high-throughput sequencing-based on 16S rDNA. Our results demonstrated that Bacteroidetes (48.04%) and Pro- teobacteria (40.66%) in all samples accounted for the majority of bacterial populations. There was a significant linear regression relationship between the abundance of bacterial phyla and culture time. Notable shifts in bacterial community composition were observed during algal growth: Flavobac- teriales accounted for the vast majority of sequences at the order level. Furthermore, the relative Citation: Liu, Y.; Kan, J.; Yang, J.; S. dohrnii Noman, M.A.; Sun, J.

Here, a combination of microscopy and high-through- put DNA sequencing was used to examine morphologi- cally cryptic and pseudo-cryptic species in the diatom genus Skeletonema from the Long-Term Plankton Time Series in Narragansett Bay (NBay), where Skele- tonema is ecologically important, comprising up to 99% of microplankton cells in surface waters. The 28S rDNA from mock phytoplankton communities compris- ing known species was amplified and sequenced using newly developed Skeletonema-specific primers. The relative abundances of species in the sequence data did not match expected abundances, suggesting that 28S copy number can vary greatly, even among closely related diatom species. The 28S rDNA was also ampli- fied from 75 field samples collected from 2008 to 2013. High-throughout DNA sequencing revealed seasonal varia- A total of 7 Skeletonema species were identified, in- tion (2008–2013) in morphologically cryptic species diversity cluding 5 newly detected species from NBay.

Theriot Salinity is a significant barrier to the distribution of diatoms, and though it is generally understood that diatoms are ancestrally marine, the number of times diatoms independently colonized fresh waters and the adaptations that facilitated these colonizations remain outstanding questions in diatom evolution. Resolving the exact number of freshwater colonizations will require large-scale phylogenetic reconstruction with dense sampling of marine and freshwater taxa. A more tractable approach to understanding the marine–freshwater barrier
