  1. 1. The circadian clock in annuals and perennials coordination of Growth with Environmental Rhythms

    Detta är en avhandling från Umeå : Umeå Universitet, Institutionen för fysiologisk botanik

    Författare :Mikael Johansson; Umeå universitet.; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; circadian clock; arabidopsis; populus; NATURAL SCIENCES Biology Cell and molecular biology Molecular biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi Molekylärbiologi; TECHNOLOGY Bioengineering Plant biotechnology; TEKNIKVETENSKAP Bioteknik Växtbioteknik; NATURAL SCIENCES Biology Organism biology Plant physiology; NATURVETENSKAP Biologi Organismbiologi Växtfysiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : Since the first signs of life on planet earth, organisms have had to adapt to the daily changes between light and dark, and high and low temperatures. This has led to the evolution of an endogenous time keeper, known as the circadian clock. LÄS MER

  3. 3. Circadian Rhythms in Moth Sex Pheromone Communication

    Detta är en avhandling från Chemical Ecology and Ecotoxicology, Department of Biology, Lund University

    Författare :Germund von Wowern; Lunds universitet.; Lund University.; [2006]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physiology of invertebrates; växtparasitologi; Entomologi; plant parasitology; Entomology; Ecology; Ekologi; locomotor activity; social synchronisation; PDH; corazonin; PBAN; pheromone response; sex phermone; Lepidoptera; Ryggradslösa djurs fysiologi; calling behaviour; circadian rhythm;

    Sammanfattning : Sex pheromone communication and related physiological processes are regulated by circadian clock mechanisms in many moth species. This thesis includes studies of circadian rhythms in sexually relevant behaviours and communication in the Egyptian cotton leafworm Spodoptera littoralis, the turnip moth Agrotis segetum, the Indian meal moth Plodia interpunctella and the Mediterranean flour moth Ephestia kuehniella.

  4. 4. Circadian rhythms in the auditory system

    Detta är en avhandling från Stockholm : Karolinska Institutet, Dept of Physiology and Pharmacology

    Författare :Vasiliki Basinou; Karolinska Institutet.; Karolinska Institutet.; [2016]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Circadian clocks have been found in numerous cell types and tissues of the body, allowing organisms to coordinate their daily biological functions. They generate cycles of behavioral and physiological processes with a period length of ~24h, which are synchronized to the rotation of the Earth and the subsequent daily changes in illumination, temperature and humidity.

  5. 5. Multiple neurotransmitter inputs modulate circadian clock neurons in Drosophila

    Detta är en avhandling från Stockholm : Zoologiska institutionen

    Författare :Yasutaka Hamasaka; Stockholms universitet.; [2006]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; circadian; Drosophila; neurotransmitter; G-protein coupled receptor; NATURAL SCIENCES Biology Cell and molecular biology Neurobiology; NATURVETENSKAP Biologi Cell- och molekylärbiologi Neurobiologi;

    Sammanfattning : Most animals have endogenous circadian clocks, which drive daily rhythms in behavior and physiology to adapt to daily cycles of the environment. Several sets of neurons have been identified as circadian pacemakers (clocks) in the brain of Drosophila melanogaster, but the neuronal circuits and neurotransmitters signalling circadian information are poorly known.
