2. 1. Novel insights into protist diversity and niche adaptation using single cell transcriptomics

   Author : Henning Onsbring; Thijs J. G. Ettema; Alastair Simpson; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Protists; microbial eukaryotes; cultivation-independent methods; single-cell RNA sequencing; phylogenomics; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

   Abstract : Protists are a polyphyletic group of microbes that represents the vast majority of eukaryotic diversity. Despite this, most sequencing efforts targeting eukaryotes have been focused on animals, fungi and plants. READ MORE

4. 2. Environmental sequencing to infer patterns of eukaryotic evolution : Combining long-read and short-read metabarcoding

   Author : Mahwash Jamy; Fabien Burki; Micah Dunthorn; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Protists; eukaryotes; environmental sequencing; ribosomal DNA; PacBio; long-read metabarcoding; phylogenetics; salt barrier; habitat evolution; eukaryotes evolution; evolutionary rate; Apicomplexa; pathogen; Biology with specialization in Systematics; Biologi med inriktning mot systematik;

   Abstract : Our view of eukaryotes is biased towards plants, animals, and fungi. But the vast majority of eukaryotic diversity is microbial in nature. These microbial eukaryotes are key players in all ecosystems on earth and are collectively known as protists. READ MORE

5. 3. Pelagic microorganisms in the northern Baltic Sea : Ecology, diversity and food web dynamics

   Author : Johnny Berglund; Agneta Andersson; Ramon Massana; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; resource limitation; predation limitation; microbial food web; heterotrophic microorganisms; nanoflagellates; ciliates; protists; resource heterogeneity; chrysomonads; chrysophytes; group-specific PCR-DGGE primers; Baltic Sea; Marine ecology; Marin ekologi;

   Abstract : Heterotrophic microorganisms are important for the flow of carbon and nutrients in the sea. Bacteria, nanoflagellates and ciliates are relevant components of the pelagic food web. In order to be able to predict the outcome of e.g. READ MORE

6. 4. Microbial evolution: patterns of diversity in aquatic protists

   Author : Ramiro Logares; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; dinoflagellates; biodiversity; lakes; Evolution; diversification; microbes; biogeography;

   Abstract : Little is known about how microbes diversify in nature. In contrast to the more studied multicellular organisms, microbes can have a) huge population sizes, b) high reproductive rates and c) long-distance dispersal. These characteristics can affect their tempo and mode of diversification in ways that still need to be understood. READ MORE

7. 5. Ancient roles of non-coding RNAs in eukaryotic evolution : contributions from social amoebae and other protists

   Author : Lotta Avesson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : RNAs not coding for proteins, non-coding RNAs (ncRNAs) have many important roles in all kingdoms of life. Especially in eukaryotes, the regulatory functions of ncRNAs have been suggested as a major force in the evolution of complex traits. READ MORE
