Lipid profiles of deep-sea organisms
… used to elucidate elements of the ecology of organisms from Mid-Atlantic and Juan de Fuca Ridge hydrothermal vents and shrimp from below a permanent oxygen minimum zone. Lipid profiles of these organisms from extreme deep-sea environments are compared. Lipid profiles of adult Mid-Atlantic …

Comparing organisms on the level of metabolism
… To improve our understanding of the phenotype of organisms it is of great value to analyze not only individual genes, but also these interaction networks. In particular the growing amount of publicly available data on metabolic pathways as well as of functional annotation data for sequenced …

How marine organisms cope with changing climate
… the oceans are becoming warmer and more acidic. Organisms need to adjust to such environmental changes and display a variety of mechanisms to maintain their fitness in novel conditions. These adjustments can operate at various levels of biological organisation: from cellular levels to organismal …

Mapping the Spatial Transcriptome Across Whole Organisms
This study utilizes Expansion Sequencing (ExSeq) to thoroughly investigate the spatial transcriptome of the Caenorhabditis elegans (C. elegans) body. Beyond mapping gene distribution within individual specimens, this research sequences multiple C. elegans to identify both shared and distinct …

Evolutionary and ecological genomics in deep-sea organisms
Hydrothermal vents and coral ecosystems are conspicuous biological hotspots in the deep-sea. These ecosystems face increasing threats from human activities. Having thorough taxonomic inventories as well as understanding species’ relatedness, diversity, connectivity patterns, and adaptive potential …

The Evolution of Social Organisms: Modelling Reproduction Strategy
… more detail at the transition from unicellular organisms to multicellular organisms, I model the macrocyst stage in the slime mould Dictyostelium. I consider how the macrocyst stage may be an early example of collective reproduction in protozoa. Here individuals aggregate to be ingested by a …

Sphingolipid synthases of Toxoplasma gondii and other organisms
Toxoplasma gondii is an obligate intracellular protozoan parasite of the phylum Apicomplexa, and toxoplasmosis is an important disease in immuno-compromised individuals - especially AIDS patients, organ transplant recipients and patients receiving anti-cancer chemotherapy. Toxoplasmosis also has …

Software Systems for Automated Manufacturing of Engineered Organisms
… test and produce new genetically modified organisms at very large scales. Automation systems are often employed at these large scales to manage and execute laboratory operations. A current challenge in the field is how to automate organism engineering during the discovery phase of research …

Dynamic Mutation Rates and Extinction in Sexual Organisms
I analyzed the dynamics of the mutation rate in both finite and infinite randomly-mating populations. Germ-line mutator alleles, alleles that increase the genomic mutation rate, frequently occur when mutations alter the structure or regulation of genes involved in DNA repair, a fraction of the …

Microaerobic requirements of camplobacter species and related organisms
A novel microaerobic incubator in which oxygen, carbon dioxide, hydrogen and nitrogen can be combined at different concentrations was used to investigate the gaseous requirements of Campylobacter species and Arcobacter species. Optimum gaseous incubation conditions were identified for all test …

The Effects of Benthic Organisms on Intertidal Sediment Erodibility
… intertidal sandflats, the dispersal of juvenile organisms can rely on bedload transport, a critical process during small-scale disturbance recovery. The erosion of surface sediments is also vital to benthic-pelagic coupling, where resuspended microbes and organic material become available to …

Forming magnetic chain with the help of biological organisms
… bacteria are one of the most interesting microorganisms, in which the assembly of nanoparticles occurs. These microorganisms are a heterogeneous group of gram negative prokaryotes, which all show the production of special magnetic organelles called magnetosomes, consisting of a magnetic …
