1. 41. Images from unmanned aircraft systems for surveying aquatic and riparian vegetation

   Författare :Eva Husson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Aquatic and riparian vegetation in lakes, streams, and wetlands has important ecological and regulatory functions and should be monitored to detect ecosystem changes. Field surveys are often tedious and in countries with numerous lakes and streams a nationwide assessment is difficult to achieve. LÄS MER

3. 42. Evolution of the G protein-coupled receptor signaling system : Genomic and phylogenetic analyses

   Författare :Arunkumar Krishnan; Helgi Schiöth; Torgeir Hvidsten; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; GPCRs; G proteins; Sensory system; Signal transduction; Olfaction; Chemosensation; Hemichordates; Sponges; Porifera; Bilaterians; Holozoans; Fungi; Opisthokonts; Bioinformatics; Bioinformatik;

   Sammanfattning : Signal transduction pathways mediated by G protein-coupled receptors (GPCRs) and their intracellular coupling partners, the heterotrimeric G proteins, are crucial for several physiological functions in eukaryotes, including humans. This thesis describes a broad genomic survey and extensive comparative phylogenetic analysis of GPCR and G protein families from a wide selection of eukaryotes. LÄS MER

4. 43. Exploration of microbial diversity and evolution through cultivation independent phylogenomics

   Författare :Joran Martijn; Thijs J.G. Ettema; Andrew Roger; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cultivation independent genomics; metagenomics; single-cell genomics; metagenomic binning; phylogenetics; phylogenomics; phylogenetic artefacts; comparative genomics; gene tree-species tree reconciliation; rRNA amplicon sequencing; Tara Oceans; origin of mitochondria; Alphaproteobacteria; Rickettsiales; Haloarchaea; endosymbiosis; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

   Sammanfattning : Our understanding of microbial evolution is largely dependent on available genomic data of diverse organisms. Yet, genome-sequencing efforts have mostly ignored the diverse uncultivable majority in favor of cultivable and sociologically relevant organisms. LÄS MER

5. 44. Genomics of Arbuscular Mycorrhizal Fungi : Expanding knowledge, one assembly at a time

   Författare :Merce Montoliu-Nerin; Anna Rosling; Hanna Johannesson; Nicolas Corradi; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; genomics; arbuscular mycorrhizal fungi; phylogenomics; DNA; evolution; Bioinformatics; Bioinformatik; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

   Sammanfattning : Most life forms that inhabit Earth today are still unknown or are difficult to study. Accessing their DNA can give us information of their biology, ecology, and evolution, even when unculturable. The research here presented focused on method development for genomic research of non-model organisms. LÄS MER

7. 45. Genomics of Sorocarpic Amoebae

   Författare :Sanea Sheikh; Sandra L. Baldauf; Matthew W. Brown; Uppsala universitet; []
   Nyckelord :;

   Sammanfattning : Sorocarpy is the aggregation of unicellular organisms to form multicellular fruiting bodies (sorocarps). This thesis is about the two best-known groups of sorocarpic amoebae, Dictyostelids and Acrasids.Paper I describes assembly and analysis of a multigene dataset to identify the root of the dictyostelid tree.
